For patients who have received corticosteroids anxiety symptoms grief cheap 5mg emsam amex, there should have been an interval of 3 weeks between the last dose of corticosteroids and the scan anxiety symptoms light sensitivity purchase emsam 5 mg on-line. The centralized reading center was blinded to the treatment assignment and the reading was performed in the absence of clinical information anxiety medication over the counter cheap emsam 5mg with amex. Following unblinding subjects were eligible to enter an open label treatment period if the investigator determined that the subject could benefit from continued (for those who were on ocrelizumab) or initiation of treatment with ocrelizumab anxiety and high blood pressure effective emsam 5 mg. Patients who discontinued treatment for any reason were to be followed up for at least 48 weeks after the last infusion in the Safety Follow-Up Period with visits every 12 weeks until 48 weeks had elapsed since the last infusion of study drug anxiety symptoms belching emsam 5mg on-line. The full schedule of assessments during the blinded treatment phase is shown in Table 99 anxiety symptoms in children facts for families discount emsam 5mg free shipping. Symptoms must have persisted for more than 24 hours and could not be attributable to confounding clinical factors such as a fever, infection, injury, or adverse reactions to concomitant medications. Episodic spasms, sexual dysfunction, fatigue, mood change or bladder or bowel urgency or incontinence did not suffice to establish a relapse. It should be noted that all patients with new neurological symptoms defined at a visit or over the phone should have been referred to the Examining Investigator unless the Treating Investigator considers the symptoms consistent with an intensification of neurological symptoms from a transient systemic infection. The following laboratory results were provided to the Treating Investigator because they were Criteria for Retreatment with Ocrelizumab (See Section 6. Confirmation of disability progression was required at a regularly scheduled visit that was at least 12 weeks after the initial disease progression. An interim data lock was to occur when the last patient had completed the Week 120 assessment. If additional treatment cycles were instituted due to lower than anticipated disease progression rates at 120 weeks, then the interim data lock was to occur when approximately 253 sustained disability progression events had occurred. An additional analysis comprising of both safety and efficacy endpoints was planned at the end of the follow-up period to investigate the maintenance of the treatment effect and/or the potential for a withdrawal effect. An assessment that occurred within 30 days after a protocol-defined relapse was not to be used for confirmation of sustained disability progression. Reviewer Comments: Note that for the primary analysis a progression could begin at a relapse. For patients who had an initial disability progression but who did not have a confirmatory visit at the time of the interim database lock the primary analysis assumes that these patients did not meet the criteria for confirmed progression. The proportion of patients with sustained disability progression was to be estimated using Kaplan-Meier methodology. The overall hazard ratio was to be estimated using a stratified Cox regression model with the same stratification factors used in the stratified log-rank test above. The sponsor subsequently proposed the "cleaning" process in an amendment dated February 25, 2013. Secondary efficacy endpoints were tested in the hierarchical order listed above, if the primary endpoint and each preceding endpoint reached the significance level of 0.

Ocrelizumab causes significant depletion of circulating B-lymphocytes soon after infusion. This review assesses the effectiveness of ocrelizumab despite unresolved manufacturing problems that prevent consistent production of a potent and stable product that may delay approval. As it is, the trial results count events that may not have occurred, show inconsistencies among important subgroups, and lack independent confirmation. In addition, there are problems with trial conduct and reasons to suspect the quality of the data. Infusion reactions, malignancies, infection, and depression-associated events are the most significant adverse events for both indications. Relapsing multiple sclerosis Two 800-patient adequate and well-controlled clinical trials provide substantial evidence of effectiveness. Over two years, the proportion of patients with disability progression events is 40% less, 15. Nevertheless, the high and unbalanced drop-out rates in the two trials (17% vs 11%, and 23% vs 14%, Rebif vs ocrelizumab) and the high percentage of disclosing side effects in the Rebif groups are likely to have introduced bias in clinical assessments and postrandomization medical care decisions. The bias increases the uncertainty about the point estimates of the relative effect of ocrelizumab compared to Rebif for relapse rate and the rate of disability progression events. The statistical reviewer notes that in a pre-specified sensitivity analysis that corrected for potential bias introduced by imputation, the p-value for the trial increased from 0. Slightly more women on ocrelizumab experienced poor outcomes compared to those on placebo. All the treatment effect occurred by 18 weeks or after the patients had been in the trial for two years and the number of active participants began to diminish rapidly. At these early and late times, there is variability in trial participation and investigators and patients lack experience with the protocol procedures. Without imputed events or observations carried forward, all secondary clinical outcomes show no significant beneficial effect using the trial hierarchy. With at least 20% dropout, fewer than 195 subjects completed the trial in the control group. An alternative conclusion would be that the results are extremely weak and do not provide evidence of a meaningful clinical effect. The trial results count events that may not have occurred, are inconsistent among important subgroups, and lack independent confirmation. In addition, there are reasons to suspect the quality of the data an, in women, there is no evidence of beneficial effect to balance the potential risk of breast cancer. Clinical data quality issues include a 20% or greater dropout rate and poor of the primary outcome variable, a lack of confirmatory evidence, and an apparent lack of treatment effect in women in general and, for all patients, for a period of two years beginning after the first 18 months of treatment. Background Document Purpose the task for this secondary review is to consolidate the reviews from the different disciplines and make recommendations for approval and labeling. The safety reviewers have decided that labeling and a required study of cancer incidence after approval will alleviate their concerns about malignancy. The evidence of the effectiveness was weakened by the failure of the study to withstand an important sensitivity analysis on un-imputed data, which is commonly used as the standard primary data for disability progression endpoint. She also mentions that ocrelizumab had no treatment benefit numerically or statistically among female patients and identifies weaknesses in the analysis of the Timed 25-Foot Walk Test, a secondary clinical outcome. Symptoms include relapsing episodes of diminished sensory or motor function that can be disabling and usually resolve within one month. Some patients have a relatively benign course; others become severely disabled after only a few years. In general, evidence of an effect on disability progression during the two-year exposure in most Dr. Extavia is Betaseron under another name and Glatopa is a generic form of Copaxone. Therefore, the links between the two forms of the disease remain the subject of ongoing research. In some of these labels, all the disability outcomes are not statistically significant but all labels describe at least one trial that showed a statistically significant effect (p-value less than 0. The team has identified serious concerns with drug product stability and potency at the time of the filing meeting. The team sent information requests to the applicant and made a site visit in order to resolve these problems. They have found no satisfactory resolution to the drug substance manufacturing and potency issues. One of the issues is degradation of one of the drug product excipients (polysorbate 20) and drug product stability. She concluded that ocrelizumab is not approvable because, at the time of her review, she could not confirm that the product used in the reproductive toxicology studies is comparable to the product used in the pivotal clinical studies and to the product intended for market. If the products are not comparable, then the applicant may need to repeat some of the nonclinical studies. Ocrelizumab causes B-cell depletion within 14 days of treatment without apparent loss of humoral immunity. General clinical pharmacology: absorption Ocrelizumab is for intravenous infusion. General clinical pharmacology: distribution the estimated volume of distribution for the central compartment is 2. Pathway of elimination, half-life, and excretion the initial time-dependent clearance is 0. Drug-drug interactions the clinical pharmacology review team does not anticipate any drug-drug interactions because ocrelizumab is a monoclonal antibody. He found no significant discrepancies between his own analyses and those of the sponsor. The evidence of the effectiveness was weakened by the failure of the study to withstand an important sensitivity analysis using only un-imputed data. The results of the single trial submitted as substantial evidence show a statistically significant but clinically small benefit that does not withstand a critical sensitivity test. Weaknesses in the results, conduct, and design preclude the single trial from providing substantial evidence of effectiveness. Each of the two sections describes pertinent features of the trial designs, presents trial results as reported by the sponsor, and then describes uncertainties in the evidence. The protocols have a double-dummy design because of different routes of administration: patients self-inject Rebif subcutaneously three times per week and receive ocrelizumab 600mg by intravenous infusion every six months. On entry to the studies, patients were in good general health and had experienced at least either two clinically apparent relapses within 2 years or one within 1 year prior to screening. For selection, investigators did not count relapses that occurred less than 30 days before the screening examination. Both trials use the same definitions of relapse and 12-week disability progression, which are the major clinical events used to determine efficacy. The pre-specified analysis for confirmed disability progression at 12 weeks was the pooled analysis of outcome events from the two trials. The table shows the independent results from each trial because the analyses for both trials showed statistical significance when analyzed separately. The p-value for the pooled analysis of disability progression confirmed at 12 weeks is 0. Figure 1 is a survival curve showing the proportion with confirmed disability progression lasting at least 12 weeks. Rodichok found that both of these disability scales had similar baseline values and both did not change significantly by week 96. The dropout rates were as low as 10% and as high as 23% in the 4 arms of the 2 trials. In each trial, there were more dropouts in the Rebif group (6% and 9% for trial 21092 and 21093, respectively; see Table 2). The ratio of the dropout rate to the absolute difference in the proportion of patients free of relapse at 96 weeks in the 4 arms of the trials ranged from approximately 1. These ratios indicate that the information lost because of dropout introduces a moderate amount of uncertainty about the trial results. In other words, unknown events that would have occurred in patients who dropped out could have produced a moderate change in the results. There is more uncertainty in the Rebif arms of the trial because of the higher dropout rates. The difference between treatment arms indicates the dropout may have been due, in some degree, to decisions informed by knowledge of treatment arm or post randomization events. Rodichok and Yan, this review concludes that, despite concerns about dropout and bias due to treatment-disclosing side effects, evidence from two adequate and well-controlled trials supports the conclusion that ocrelizumab reduced the annualized relapse rate in patients with relapsing multiple sclerosis compared to Rebif. Ocrelizumab also reduced the proportion of patients who experienced episodes of disability progression lasting 12 weeks or longer, a secondary outcome. The date of the first version of the statistical analysis plan is December 20, 2013, 36 a year after randomization of the last patient on December 27, 2012, and 6 months after Version D of the protocol, dated June 15, 2012, came into effect. For adequate power, there must be 253 disability events to detect the planned treatment difference. The trial was to end 120 weeks after randomization of the last patient unless 253 disability progression events had not occurred. The number of patients randomized is 102 patients more than the 630-patient sample size that the protocol specifies. In the study report, the applicant uses imputed values and reports a p-value of 0. This means that all the secondary outcomes, except 24-week disability progression, achieved only nominal statistical significance because of the pre-specified hierarchy.

The varied pathologic subtypes, for the most part at present, do not materially affect the dose or field decisions to be made in this disease. Respiratory gating techniques and image guidance techniques may be appropriate to minimize the amount of critical tissue (such as lung) that is exposed to the full dose of radiation. Initial management will usually require chemotherapy (in a variety of different acceptable regimens), followed by assessment of response, leading to an appropriate choice of doses and fields of radiation therapy. Chemotherapy alone may be appropriate for early stage non-bulky disease, with radiation therapy reserved for relapse.

Radiation is not medically necessary in the definitive or adjuvant treatment of renal cell cancer 140B Fractionation I. In the palliative setting, up to 20 fractions is medically necessary 142B Techniques I. A partial nephrectomy can be used in the treatment of early stage renal cell cancer while an open radical nephrectomy is used with locally advanced disease. There is no benefit with radiotherapy in the adjuvant or neo-adjuvant setting in the treatment of renal cell cancer (Escudier, 2014). In an individual with unresectable disease or recurrent disease, radiation can be utilized to improve local control (Mourad, 2014). However, there are no prospective studies examining this issue, and current standard of care for patients with inoperable localized renal cell cancer include radio frequency or cryo-ablative therapies (Mourad, 2014). For nonmetastatic adrenocortical cancer, adjuvant radiation can be considered for an individual with high risk of recurrence including one with positive margins, ruptured capsule, large size (> 7 cm), or high grade (Sabolch, 2015). Adjuvant radiation therapy improves local control after surgical resection in patients with localized adrenocortical carcinoma. Definitive external beam photon radiation therapy is medically necessary for an individual with either: 1. Preoperative (neoadjuvant) external beam photon radiation therapy is medically necessary for an individual with either: 1. Postoperative external beam photon radiation therapy is medically necessary for an individual with one or more of the following: 1. Palliative external beam photon radiation therapy is medically necessary in an individual with: 1. Definitive external beam photon radiation therapy is medically necessary for an individual with: 1. Limited stage disease, defined as disease which is limited to the thorax and that can be entirely encompassed in a radiation field 2. Extensive stage disease in which all systemic disease (metastases) has complete or near-complete resolution with chemotherapy B. Local control and 2-year survival were better with 60 Gy in 6 weeks compared with lower doses. Cisplatin-vinblastine for two cycles followed by thoracic external beam photon radiation therapy to a dose of 60 Gy in 6 weeks was compared with the same external beam photon radiation therapy alone in 155 randomized patients. By accounting for tumor motion on an individualized basis, smaller margins can be utilized thereby decreasing exposure to normal lung tissue. One approach to this problem is the use of respiratory gating or breath-hold technique. Gating the treatment with the respiratory cycle or treating with breath hold can help to reduce the planning target volume or avoid marginal miss. With this technique temporal changes in tumor position and anatomy are incorporated into the treatment planning process. External beam photon radiation therapy delivery that adjusts in real-time to changes in tumor and normal anatomy holds further promise to decrease the necessary tumor margin and exposure to uninvolved lung. With this technique, the intensity of the beam is spatially varied in real time and delivery is accomplished using multiple fields at different angles or with rotational arc therapy. The primary disadvantage is that a greater volume of normal tissue gets low doses. Since the normal lung has low tolerance to even small doses, this technique is not appropriate in the majority of cases of locally advanced non-small cell carcinoma. There was a trend towards increased treatment-related deaths in the highdose population (8 vs. Following publication of the official results of 0617, several additional analyses of the data emerged which have provoked controversy in the literature. In their evaluation of pulmonary toxicity, the authors stated no difference in survival. Grade 3 esophagitis, dysphagia, weight loss and cardiovascular toxicity were not different. In their editorial, they questioned whether the 0617 analysis was a true planned secondary evaluation and noted that interstitial lung disease, as well as other risk factors, were not taken into account. Kong and Wang (2015) reviewed the non-dosimetric risk factors for radiation induced pulmonary toxicity. Age, sex, smoking status, pre-existing lung disease, pulmonary function, tumor location, volume stage, biologic and genetic factors, may also play a strong role in radiation treatment toxicity and possible outcomes. Similarly, in assessing cardiac effects, current cardiac status and potential cardiac risk factors should be taken into account in trial design. However, with improvements in modern staging and more generalized use of multimodality therapy, there may be subsets of individuals with clinical N2 disease who might benefit from surgery. Attempts have been made to "downstage" individuals with preoperative chemoradiotherapy. The dose of radiation in the preoperative setting is generally 45 Gy in25 fractions of external beam photon radiation therapy. Similarly, respiratory gating techniques may also be helpful, particularly for lower lobe primary tumors. In the entire group of patients, there was a 7% absolute reduction in survival for patients who received external beam photon radiation therapy. The trials included in the meta-analysis have a variety of serious pitfalls, including the inclusion of ineligible patients, inadequate staging work-up, inclusion of node-negative patients, and techniques that today would be expected to produce deleterious outcomes. In many of the trials, opposed off-cord lateral fields were used, which exposes a significant volume of normal lung to intolerable radiation volume, dose per fraction and total doses. Additionally, systemic therapy was not used, and improved local control is more likely to translate into a survival benefit if effective systemic therapy is available. An individual with N2 disease is likely to achieve a significant local control benefit from postoperative external beam photon radiation therapy, and with modern techniques the individual may accrue a survival benefit. Patients were randomized to 30 Gy in 15 fractions versus observation after definitive local therapy. Results of effects on neuropsychological function and quality of life are not yet available. An individual with hilar nodal involvement should be treated with standard fractionation. Patients with central tumors can experience excessive toxicity when higher fraction sizes and fewer fractions. Oligometastatic presentations/genetic variants 152B Lung cancer may present in an intermediate phase where cancer may be limited to the primary region with three or fewer metastatic sites that are also amenable to definitive treatment. Requests for definitive radiation treatment to the primary site will be considered on a case-by-case basis. As such, circumstances may present where a more protracted radiation therapy regimen may benefit these patients rather than a short-term palliative regimen when substantial benefit has been gained from systemic therapy. The use of radiation therapy in this setting will also be reviewed on a case-by-case basis. In addition, external beam photon radiation therapy is effective in the palliation of symptoms due to local tumor, such as hemoptysis, cough, or imminent endobronchial obstruction. There was no difference between arms, and 60% of patients achieved symptom relief. Similar palliation was seen in both arms, although patients in the 20 Gy arm had longer median survival. The Medical Research Council compared 17 Gy in 2 fractions (one per week) with 30 Gy in 10 fractions over 2 weeks. Hemoptysis was relieved in 86% of patients, cough in approximately 60% of patients, and pain in approximately 50% of patients. Therefore, data supports the use of short hypofractionated regimens, and there is generally no Radiation Therapy Criteria V2. Concerns regarding neurocognitive defects are obviated by avoiding high dose per fraction treatment and concurrent chemotherapy. In selected individuals with extensive disease, a shorter course, such as 20 Gy in 5 fractions may be appropriate. Higher doses have not proved beneficial and are associated with more neurocognitive deficits. In the few cases of clinical stage T1-T2N0 disease, surgery establishes the diagnosis and effectively removes the primary tumor. Such individuals should also be staged with mediastinoscopy, and if mediastinal lymph nodes are negative, chemotherapy alone can be entertained. Concurrent chemo-radiotherapy leads to improved survival as compared with sequential therapy. Standard external beam photon radiation therapy fractionation consists of either 45 Gy given at 1. Local thoracic external beam photon radiation therapy for individuals with extensive stage disease is not an established approach, however, in selected individuals it may be considered, such as those with clinically apparent disease only at the primary site and complete response elsewhere.

Medical management should include both sedation with benzodiazepines and pain relief with narcotics. Narcotics alone may be insufficient in the management of air hunger and respiratory distress at the end-of-life. Habituated patients or those who are difficult to sedate are candidates for evaluation by Anesthesia/Pain Management specialists. Because of the unique nature of the palliative care environment, medication dosing frequently differs from usual recommendations for analgesia or conscious sedation in neonates. It is important to anticipate the acute symptoms expected when a patient is extubated. First doses of medication should be given prior to extubation, and an adequate level of sedation should be achieved to avoid patient air hunger. All medications other than those needed to promote comfort should be discontinued, unless otherwise requested by the family. Exceptions may include anti-epileptics, which offer seizure control and provide some level of sedation but should not be considered the primary sedative. If the infant was receiving neuromuscular blockade prior to the transition to comfort care, special attention should be paid to assure patient comfort under any residual paralytic effect. Of note, morphine has several advantages over other narcotics in end-of- life care, and is especially effective at decreasing shortness of breath and air hunger. Fentanyl bolus dosing may not provide adequate pain control for a dying infant secondary to its short half-life. Infants receiving a fentanyl infusion should also receive a bolus morphine dose immediately prior to discontinuation of support, or in the event of observed distress. Pharmacologic Management at the End f Life consult with a member of Critical Care Medicine due to their expertise in assessing brain death. Transitioning to Conventional Ventilation, Decreasing Ventilatory Support, and Removal of Endotracheal Tube If the infant has been maintained on high frequency oscillatory ventilation, they should be transitioned to conventional ventilation to facilitate parental holding and bonding prior to extubation. The ventilator settings may be gradually decreased over a short period of time to assure that pain management and sedation is adequate; if the infant appears uncomfortable the titration of medications should be increased prior to the removal of the endotracheal tube. There is no need to monitor blood gases or chest imaging while weaning the ventilator prior to extubation. The process of weaning the ventilator will also increase hypoxemia and hypercarbia, which may contribute to the level of sedation. Pronouncing the Death the physician of record or fellow acting under the physician of record should always document the time of death in the chart. The family should again be informed that despite all available interventions, the known outcome for their infant remains unchanged. The option of continuing current support to give the parents time for memory-making with their baby may be offered as a bridge to the transition to comfort care. Organ Donation LifeGift Organ Donation Center should be notified within one hour of the patient meeting an imminent death trigger or at cardiac time of death. If the patient is a potential organ donor, LifeGift will "follow" the patient and will consult regularly with the medical team. All cardiac times of death should be called into LifeGift on any patient 19 weeks of gestation or older, and should be documented on the "pink sheet. Per the policy, at least two different services must perform the brain death exam. Along with Neurology, it is advisable to 214 713-906-2377 (mobile) 713-328-0662 (office) epassy@lifegift. The medical examiner is available 24 hours a day, 7 days a week including all holidays. In the State of Texas, notification of the medical examiner is required for all dead children under 6 years of age. If the body is not released, the medical examiner will perform a mandatory autopsy. If the body is released by the medical examiner, parental consent for an autopsy should be discussed shortly after death. Studies have consistently shown that in approximately 30 to 50% of cases, the diagnosis of the infant was changed or new information was found at autopsy. Although autopsies may only be helpful in informing the family predicting recurrence risk in future pregnancies and future diagnostic testing of siblings in 6-10% of cases, the information may still be helpful. Although restrictions may be placed on the extent of the examination, an unrestricted, complete examination will provide the most comprehensive information and will have no impact on an open casket viewing. The procedure is completed within 3 to 4 hours, and the body is available to the funeral home on the same day. In these cases, the pathology department does request that the chest of the infant is included in the evaluation if the parents agree. Genetic testing on blood or tissue may also be obtained without performing a complete autopsy. However, a pathologist is on-call 24 hours a day 7 days a week, and an autopsy may be performed at any time if clinically indicated. Physicians and medical professionals caring for the patient are encouraged to attend the autopsy and discuss specific questions to be addressed with the pathologist. A verbal report is usually available in 72 hours and preliminary results within 7-10 days. The "follow-up" physician is responsible for contacting the family and initiating a post-autopsy consultation. Parents should be provided with a copy of the autopsy report at the time of the meeting. When requesting an autopsy, a copy should be sent to Denita Wallace, as well as the follow-up physician. Or they may want the opportunity to visit with hospital staff who cared for their child. As physicians it is our obligation to aid parents in the grieving process to the extent they desire. The follow-up attending should be the regular daytime attending assigned to the infant, and not necessarily the attending on-call. In the event that a follow-up attending is not identified, Denita Wallace and Frank Placencia will use their discretion in identifying the follow-up attending. The social workers routinely contact all families of deceased infants 1 month after death. At that contact, they will ask the family if they wish to be contacted by the follow-up physician. That information will be forwarded to the follow-up attending who will call interested families and offer to meet with them. It is advisable to have the social worker present during the phone call and meeting to address issues beyond the scope of our training. This meeting is in addition to the autopsy review meeting, which usually happens closer to 2-3 months after death. After the phone call and/or meetings, a note should be entered into the chart for documentation purposes. Hospice care provides a sup- port system for families with children discharged from the hospital with an irreversible or terminal condition. There are no time limits for referral to hospice care, and this care may be provided in a facility or at home. The assigned social worker can help with placement, and should be contacted for all referrals. The family should be instructed to call the hospice rather than emergency personnel in the event of a home death. Hospice and numbness are most intense in the first 2 weeks, followed by searching and yearning from the second week to 4 months, then disorientation from 5 to 9 months, and finally reorganization/resolution at 18 to 24 months. Up to one quarter of bereaved parents may display severe symptoms years after the death of their baby. Perinatal Hospice Some parents confronted with a lethal fetal diagnosis may decide to continue their pregnancy to its natural conclusion. Consideration of hospice care is appropriate if the baby does not expire soon after birth. Funeral Homes the family will be assisted with obtaining a funeral home for their deceased child by the appointed social worker or nursing staff. The nursing staff is guided by a checklist which enables them to deliver care at the time of death in a uniform fashion to each family, including bereavement support materials, a sympathy card, and information on funeral homes in English or Spanish. Support systems for bereaved parents may be weak, and community insensitivity is not uncommon. Bereaved parents often face caring for other children while mourning one or more who died, especially in cases of multiple births with one or more losses. Parents anticipating the death of their child may feel conflicting emotions of relief intermixed with sadness at the time of death. In addition, parents may grieve in different ways, and may not be available to each other as sources of support while experiencing their individual sorrow. Unresolved or delayed grief may result in a complicated grief reaction, and additional stressors including mental illness, low socioeconomic background, or a history of substance abuse can prolong and negatively impact the resolution of grief and integration of the loss. Psychiatric referral should be made for parents or family members experiencing atypical grief patterns. Special Circumstances Relating to Fetal or Infant Death Religious, Cultural, and Socioeconomic Differences Surrounding Death and Grieving Nursing Bereavement Support Checklist Religion and spirituality can be a source of comfort in the midst of loss. Asking open-ended questions such as "What are your beliefs and how can we meet your spiritual needs These stages are denial, anger, bargaining, depression and acceptance and are not always experienced in a linear fashion. The chaplain is trained to make an assessment and provide the family with appropriate spiritual care and religious resources. For some families, eye contact and touch may be expected; for others it may not be appropriate in their culture. Some cultures forbid autopsy, some parents may not wish to hold their dying or dead infant. In families of lower socioeconomic status, they may view the cessation of intervention as a cost-cutting measure aimed at them. It will be necessary to explain to parents that their ability to pay is not the factor that determines goals of care for their child. These type issues exemplify the importance of providing culturally competent care in this setting Telling parents that many caretakers might prefer palliative care for their own infants in the same situation may allow parents to see that their infant is not a subject of discrimination. A hospital-employed medical interpreter should always be used for conversations regarding end-of-life care. If parents consent to an autopsy, the attending neonatologist must write "Requesting autopsy to determine cause of death" in a progress note or attestation of the death note in addition to autopsy consent being filled out appropriately. Each family is provided with bereavement support materials, a sympathy card, and information on the grieving process and support services outside the hospital in English or Spanish prior to discharge. All families that provide contact information with our team receive follow up phone calls and sympathy cards at key points in their grieving process. Self-Care Working with the bereaved makes us aware of our own experienced and feared losses. If we have not appropriately mourned and re-located our own grief, it will be reexperienced in our interactions with families and predispose us to burn-out and compassion fatigue.

Child Life services is a field devoted to the psychosocial needs of hospitalized children and their families. In the nurseries, Child Life focuses on developmental needs of newborns, parent support, parent education, and sibling support and preparation. Specifically, Child Life can provide developmental support for infants identified to be at high risk for developmental delays and can offer hospitalized infants a variety of sensory and motor experiences that may facilitate development. Since infants view Child Life Specialists as safe, they can provide infants with noninvasive tactile stimulation and cuddling. Child Life offers play and development classes for the parents of healthy infants to promote parental involvement and strong parent-infant bonding. Individual support and education can be offered to parents who may have a difficult time attaching to their infant or who seem very scared and uncomfortable about touching and holding their infant. Child Life also can work with siblings who might be concerned about the baby who remains hospitalized.
