An ethical analysis of conditional and partially directed live kidney donation among strangers-The Israeli experience.

Living donor kidney transplantation (LDKT) is one of the most effective treatment options for people with end-stage renal disease. Traditionally, LDKT can be either "directed" or "nondirected," based on whether the recipient is specified by the donor. Recently, there has been an increase in conditional and semidirected live kidney donation among strangers, where the donor specifies the characteristics of the recipient whom they wish to donate to. This practice has both gained popularity and sparked controversy in the state of Israel through the nonprofit organization Matnat Chaim. We analyze the ethical implications of this practice by applying traditional principles of medical ethics to conditional LDKT. Although semidirected and conditional LDKT presents some ethical challenges, overall, its practice effectively aligns with core ethical principles. The donors' right to make stipulations respects the donor's autonomy, the practice avoids harm and benefits both donor and recipient, and justice and utility are upheld as the practice specifically benefits marginalized patients and optimizes resource utilization. Finally, we present data from our institution demonstrating how conditional LDKT increased transplantation for all ethnic groups; Jewish recipients of LDKT increased by 151.32% (P = .034) Arab recipients of LDKT increased by 111.11% (P = .036).

Weaker SARS-CoV-2 vaccine responses in nonalcoholic fatty liver disease with advanced liver fibrosis.

Background: SARS-CoV-2 vaccine responses that could harbor potential risks to chronic liver diseased patients. Aims: To assess immune response following Pfizer's SARS-CoV-2 vaccine in patients with different liver fibrosis severities of nonalcoholic fatty liver disease (NAFLD). Methods: Clinical and histological (NAS-score and fibrosis stage) characteristics of NAFLD patients before vaccine were correlated with serologic vaccine responses of two doses of the BNT162b2. Serum SARS-CoV-2 spike immunoglobulins (anti-S) were assessed on day seven following immunization (Liaison assay). Results: The mean-age of patients (n = 157) was 56.9 ± 13.2 years (46.5 % males). 94.8 % had a positive response (anti-S levels ≥ 19 AU/ml). The anti-S cutoff of 200 AU/ml used to separate strong vs. weak responses. A strong response (anti-S titers ≥ 200 AU/ml) was observed in 93/157 (59.2 %) patients with a mean-age of 53.1 ± 13.8 years (45.2 % males). A weak response (anti-S titers < 200 AU/ml) was observed in 64/157 (40.8 %) cases with a mean-age of 62.3 ± 10.2 years (p < 0.0001). The strong response subgroup had lower metabolic comorbidities, including glucose hemostasis, hypertension, and dyslipidemia (p < 0.04). Moreover, the strong response subgroup had fibrosis stages F0-F2 (75.3 % vs. 56.3 %) and lower rates of advanced stages F3-F4 (24.7 % vs. 43.8 %). The F0-F2 subgroups had significantly higher rates of strong responses than the F3-F4 stages. The anti-S ≥ 200 and anti-S ≥ 400 AU/ml response achieved in 66 % and 36.8 % of the F0-F2 population was significantly higher than the 45.1 % (p = 0.006) and 23.5 % (p = 0.05) in the F3-F4 population, respectively. The Fib-4 calculations and Fibroscan evaluations were consistent with histologic fibrosis assessment. Conclusion: Advanced liver fibrosis (assessed by histology, Fib-4, or Fibroscan) is a risk factor for lower response to Pfizer's BNT162b2 vaccine, and patients should be prioritized for the vaccine booster against SARS-CoV-2.

The diagnostic accuracy of endoscopic ultrasound vs. contrast-enhanced computed tomography in local staging of pancreatic adenocarcinoma: a bi-national multicenter study.

BACKGROUND: Identification of pancreatic cancer (PC) local invasion is crucial to optimize patients' selection for surgery. AIMS: To determine the diagnostic accuracy of contrast-enhanced computed tomography (CECT) and endoscopic ultrasound (EUS) in local staging of PC. METHODS: We performed a multicenter study including all patients with PC who underwent surgery. RESULTS: One hundred twelve patients were included. Surgical findings of peri-pancreatic lymph nodes (LN), vascular and adjacent organ involvement were seen in 67 (59.8%), 33 (29.5%) and 19 patients (17%), respectively. The diagnostic performance of EUS was better than CECT in peri-pancreatic LN. The sensitivity, specificity, positive predictive value (PPV) and negative predictive (NPV) of CECT vs. EUS were 28.4%, 80%, 67.9% and 42.9% vs. 70.2%, 75.6%, 81% and 63%, respectively. For vascular and adjacent organ involvement, the sensitivity, specificity, PPV and NPV were 45.5%, 93.7%, 75%, 80.4% and 31.6%, 89.2%, 37.5% and 86.5% for CECT, respectively, vs. 63.6%, 93.7%, 80.8%, 86.1% and 36.8%, 94.6%, 58.3% and 88% for EUS, respectively. Combining both CECT and EUS, the sensitivity for peri-pancreatic LN, vascular and adjacent organ involvement improved (76.1%, 78.8% and 42%), respectively. CONCLUSION: EUS was superior to CECT in local staging. Combined EUS and CECT had a higher sensitivity than either alone.

SARS-CoV-2 vaccine alleviates disease burden and severity in liver transplant recipients even with low antibody titers.

BACKGROUND AND AIMS: We retrospectively assessed the clinical Pfizer's mRNA SARS-CoV-2 BNT162b2 vaccination outcomes and the serologic impact on liver transplant (LT) recipients. PATIENTS AND METHODS: One hundred and sixty-seven LT cases followed between March 1, 2020 and September 25, 2021, and were stratified into two groups: (1) 37 LT recipients after SARS-CoV-2 infection before vaccine era and (2) 130 LT recipients vaccinated with 2 doses without earlier SARS-CoV-2 exposure. Serum SARS-CoV-2 spike immunoglobulins (anti-S) were assessed 7 days following vaccination (Liaison assay). RESULTS: In addition to the 37 nonvaccinated cases (22.2% of total group) who experienced SARS-CoV-2 infection (34 symptomatic and 3 asymptomatic), another 8 vaccinated symptomatic recipients (4.8%) were infected (5 from the third and three from the fourth waves). Three of the 45 infected cases died (6.7%) before the vaccine program. Vaccinated group: of the 130 LT vaccinated recipients, 8 (6.2%) got infected postvaccination (added to the infected group) and were defined as clinical vaccine failure; 38 (29.2%) were serological vaccine failure (total failure 35.4%), and 64.6% cases were serological vaccine responders (anti-S≥19 AU/mL). Longer post-LT interval and lower consumption of immunosuppressants (steroids, FK506, and mycophenolate mofetil) correlated with favorable SARS-CoV-2 vaccine response. Mammalian target of rapamycin inhibitors improved vaccine outcomes associated with lower FK506 dosages and serum levels. Patients with anti-S levels <100 AU/mL risked losing serologic response or being infected with SARS-CoV-2. A booster dose achieved an effective serologic response in a third of failures and most responders, securing better and possibly longer protection. CONCLUSION: Pfizer's BNT162b2 vaccine seems to lessen SARS-CoV-2 morbidity and mortality of LT recipients even with weak serological immunogenicity. Switching mycophenolate mofetil to mammalian target of rapamycin inhibitors might be effective before boosters in vaccine failure cases. A booster vaccine should be considered for nonresponders and low-responders after the second dose.

A DNA methylation atlas of normal human cell types.

DNA methylation is a fundamental epigenetic mark that governs gene expression and chromatin organization, thus providing a window into cellular identity and developmental processes1. Current datasets typically include only a fraction of methylation sites and are often based either on cell lines that underwent massive changes in culture or on tissues containing unspecified mixtures of cells2-5. Here we describe a human methylome atlas, based on deep whole-genome bisulfite sequencing, allowing fragment-level analysis across thousands of unique markers for 39 cell types sorted from 205 healthy tissue samples. Replicates of the same cell type are more than 99.5% identical, demonstrating the robustness of cell identity programmes to environmental perturbation. Unsupervised clustering of the atlas recapitulates key elements of tissue ontogeny and identifies methylation patterns retained since embryonic development. Loci uniquely unmethylated in an individual cell type often reside in transcriptional enhancers and contain DNA binding sites for tissue-specific transcriptional regulators. Uniquely hypermethylated loci are rare and are enriched for CpG islands, Polycomb targets and CTCF binding sites, suggesting a new role in shaping cell-type-specific chromatin looping. The atlas provides an essential resource for study of gene regulation and disease-associated genetic variants, and a wealth of potential tissue-specific biomarkers for use in liquid biopsies.

Effect of Age on Liver Transplantation Recipient Outcomes: Two Centers' Experience.

BACKGROUND: Liver diseases epidemiology has changed with advances in perioperative care. Transplantation at large centers is favorable among older and younger recipients. Local limitations on transplantation for recipients older than 65 years were cancelled in 2014. This study evaluates the effects of age on the transplantation outcome of Israeli patients in the era after removal of the limitations on recipient age. METHODS: This retrospective analysis examined prospective data on patients older than 18 years who underwent liver or liver-kidney transplantation between 2014 and 2019 at 2 transplantation centers. Patients were divided into 4 age groups (group 1: ≤59 years; group 2: 60-64 years; group 3: 65-69 years; and group 4: ≥70 years). Each group's associations of pretransplantation factors with outcome and survival were examined. RESULTS: Two hundred sixty-one recipients underwent 269 transplantations (mean age: 53 ± 12.61 y). There were 181 male (67.8%) and 88 female recipients (67.28%). Overall, 207 patients (79.6%) survived ≥12 months. One-year survival rates were 82.9%, 73.2%, 71.4%, and 93.8% for groups 1 to 4, respectively (not statistically significant; P = .11). One-year graft survival was similar between groups. More patients with chronic obstructive pulmonary disease, diabetes mellitus, or ischemic heart disease tended to survive <12 months. Cardiovascular complication was more common in older groups and affected survival. CONCLUSION: Patient age alone should not be used to deny access to transplantation, which could benefit older nonfrail individuals. However, risk factors such as male sex, chronic obstructive pulmonary disease, ischemic heart disease, diabetes mellitus, and concomitant kidney-liver transplantation should be carefully considered.

The effect of atrophied pancreas as shown in the preoperative imaging on the leakage rate after pancreaticoduodenectomy.

Backgrounds/Aims: The soft texture of the pancreas parenchyma may influence the incidence of pancreatic leakage after pancreaticoduodenectomy (PD). One possible method to assess pancreatic texture and atrophy, is via computed tomography (CT) scan of the abdomen. The purpose of our study was to evaluate the relation between the preoperative CT scan and the incidence of pancreatic fistula after PD. Methods: A retrospective single-center study including patients who underwent PD for a benign and malignant tumor of the periampullary region between the years 2000 and 2016. Demographic and imaging data were analysed and a correlation with the post-operative leak was evaluated. Results: Pancreatic leak was documented in 34 out of 154 (22.1%) patients. All the leakage cases occurred in the preserved pancreas group (33.1% of the total preserved pancreas group alone). No leak was documented in the atrophic pancreas group. This difference between the two groups was found to be statistically significant (p ≤ 0.00001). Conclusions: Atrophic pancreas in the preoperative CT scan may be protective against leakage after PD. These findings may help the surgeon to risk stratify patients accordingly. In addition, the findings suggest that patients with a preserved pancreas may require more protective methods to prevent leakage.

An analysis of 77 cases of pancreatic injuries at a level one trauma center: Outcomes of conservative and surgical treatments.

Backgrounds/Aims: Traumatic pancreatic injury (TPI) is rare as an isolated injury. There is a trend to perform conservative treatment even in patients with complete duct dissection and successful treatment. This study reviewed our 20 years of experience in the management of TPI and assessed patient outcomes according to age group and treatment strategy. Methods: A retrospective analysis of patients diagnosed and treated with TPI at a level-I trauma center from 2000-2019. Patients were divided into two groups: adults and pediatrics. Conservative treatment cases were subjected to subgroup analysis. Level of evidence: IV. Results: Of a total of 77 patients, the mean age was 24.89 ± 15.88 years. Fifty-six (72.7%) patients had blunt trauma with motor vehicle accident. Blunt trauma was the predominant mechanism in 42 (54.5%) patients. Overall, 38 (49.4%) cases had grade I or II injury, 24 (31.2%) had grade III injury, and 15 (19.5%) had grade IV injury. A total of 30 cases had non-operative management (NOM). Successful NOM was observed in 16 (20.8%) cases, including eight (32.0%) pediatric cases and eight (15.4%) adult cases. Higher American association for the surgery of trauma (AAST) grade of injury was associated with NOM failure (16.7% for grade I/II, 100% for grade III, and 66.7% for grade IV injury; p = 0.001). An independent factor for NOM failure was female sex (69.2% in females vs. 29.4% in males; p = 0.03). Conclusions: High AAST grade TPI is associated with a high rate of NOM failure in both pediatric and adults.

Advanced Liver Fibrosis Correlates With Impaired Efficacy of Pfizer-BioNTech COVID-19 Vaccine in Medical Employees.

The Pfizer-BioNTech coronavirus disease 2019 (COVID-19) vaccine has been offered to nonallergic ≥16-year-old Israeli adults since December 19, 2020. Data regarding factors associated with vaccine ineffectiveness are limited. The aim of this study is to assess the impact of hepatic fibrosis on the efficacy of the BioNTech vaccine. Serum severe acute respiratory syndrome coronavirus 2 spike immunoglobulins (S IgG) obtained at least 7 days following vaccination completion was correlated with the prevaccine calculated Fibrosis-4 (FIB-4) score among 719 employees in the Hadassah Medical Center, Jerusalem. Positive vaccine response (S IgG levels ≥ 19 AU/mL) was found in 708 of 719 individuals (98.5%). Vaccine failure (S IgG levels < 19) was found in 11 (1.5%); of these, 7 were immunosuppressed. Mean FIB-4 available in 501 of 708 vaccine responders was 1.13 ± 0.66, mean age 51.4 ± 12.4 years (29.3% males), and mean S IgG titers 239.7 ± 86.1 AU/mL. Similar to the general population, 70.5% had normal FIB-4 (<1.3), 26.8% undetermined FIB-4 (1.3-2.67), and 2.7% advanced FIB-4 (>2.67). When divided into response subgroups, 158 of 501 individuals (30.1%) with IgG titers 19-100 AU/mL had a mean FIB-4 of 1.48 ± 0.82; 198 (39.5%) with IgG titers 101-200 AU/mL had mean FIB-4 of 1.22 ± 0.76; 83 (16.6%) with titers 201-300 AU/mL had mean FIB-4 of 1.04 ± 0.48; 38 (7.6%) individuals with IgG titers 301-400 AU/ml had a mean FIB-4 of 1.08 ± 0.63; and 121 (24.2%) with IgG titers >400 AU/mL had mean FIB-4 of 1.18 ± 0.87. Increased FIB-4, age, and male gender significantly correlated with lower postvaccine IgG titers (P < 0.001). FIB-4 results were confirmed using FibroScan data displaying advanced fibrosis impact on weakened COVID-19 vaccine response. Conclusion: Immune suppression, older age, male gender, and advanced chronic liver disease are risk factors for lower vaccine response. The FIB-4 provides a simple tool to prioritize candidates for third-dose vaccine booster.

Impact of tozinameran (BNT162b2) mRNA vaccine on kidney transplant and chronic dialysis patients: 3-5 months follow-up.

BACKGROUND: Determining the humoral immunogenicity of tozinameran (BNT162b2) in patients requiring chronic renal replacement therapy, and its impact on COVID-19 morbidity several months after vaccination, may guide risk assessment and changes in vaccination policy. METHODS: In a prospective post-vaccination cohort study with up to 5 months follow-up we studied outpatient dialysis and kidney transplant patients and respective healthcare teams. Outcomes were anti S1/S2 antibody responses to vaccine or infection, and infection rate during follow-up. RESULTS: One hundred seventy-five dialysis patients (40% women, 65 ± 15 years), 252 kidney transplant patients (33% women, 54 ± 14 years) and 71 controls (65% women, 44 ± 14 years) were followed. Three months or longer after vaccination we detected anti S1/S2 IgG antibodies in 79% of dialysis patients, 42% of transplant recipients and 100% of controls, whereas respective rates after infection were 94%, 69% and 100%. Predictors of non-response were older age, diabetes, history of cancer, lower lymphocyte count and lower vitamin-D levels. Factors associated with lower antibody levels in dialysis patients were modality (hemodialysis vs peritoneal) and high serum ferritin levels. In transplant patients, hypertension and higher calcineurin or mTOR inhibitor drug levels were linked with lower antibody response. Vaccination was associated with fewer subsequent infections (HR 0.23, p < 0.05). Moreover, higher antibody levels (particularly above 59 AU/ml) were associated with fewer events, with a HR 0.41 for each unit increased in log10titer (p < 0.05). CONCLUSIONS: Dialysis patients, and more strikingly kidney transplant recipients, mounted reduced antibody response to COVID-19 mRNA vaccination. Lesser humoral response was associated with more infections. Measures to identify and protect non-responsive patients are required.

Weight Loss Outcomes and Lifestyle Patterns Following Sleeve Gastrectomy: an 8-Year Retrospective Study of 212 Patients.

PURPOSE: Sleeve gastrectomy (SG) is an effective treatment for extreme obesity; however, long-term weight loss outcomes remain largely understudied. We aimed to examine the long-term weight changes following SG and patient characteristics and lifestyle patterns related to weight loss outcomes. MATERIALS AND METHODS: Data from medical records of patients operated in a tertiary university medical center between 2008 and 2014 were reviewed, along with information derived from a telephone questionnaire. Information included the following: current medical status, medications, side effects, behavior, lifestyle habits, and weight changes. RESULTS: A total of 212 patients (69.3% females) were included, with a median follow-up duration of 8 years post-SG. Mean age and baseline body mass index (BMI) of participants were 39.7 ± 12.0 years and 42.2 ± 4.9 kg/m2, respectively. Mean BMI, percentage excess weight loss, and percentage total body weight loss were 33.1 ± 6.1, 55.5 ± 27.5%, and 21.7 ± 10.7%, respectively. Higher baseline BMI was found to be the strongest independent predictor for insufficient weight loss (OR = 0.90, P = 0.001, 95% CI 0.85, 0.96). Sweetened beverage intake, usage of psychiatric medications, higher initial BMI, and lower age were significant predictors for increased weight gain from nadir weight (P < 0.0001, P = 0.005, P = 0.035, and P < 0.0001, respectively). CONCLUSIONS: SG patients were found to maintain a notable long-term weight loss. Nevertheless, weight regain and insufficient weight loss were prevalent in the long-term post-operative period, and were related to certain lifestyle patterns. Clinical practice should emphasize the relationship between post-operative weight loss outcomes and specific behaviors. Efforts should be made to educate patients on the need for lifelong follow-up and support.

The Effect of a 26-Hour Fast in Living Kidney Donors.

BACKGROUND: Living kidney donation is widely practiced, and short- and long-term outcomes are acceptable. Within the living kidney donor population there are unique ethnic groups who practice customs that affect kidney function. In Judaism, Yom Kippur (Day of Atonement) is a 25- to 26-hour fast practiced yearly. There are no studies describing the effect of this fast on LKDs. METHODS: Living kidney donors were approached via e-mail. Exclusion criteria were conditions considered prohibitive of fasting. Control participants were potential living kidney donors approved by the standard medical evaluation but that had not yet donated. Blood and urine samples were obtained at 3 time points: baseline: 3 months before fast; fasting: 1 hour after fast; and follow-up: 14 days after fast. RESULTS: In total, 85 living kidney donors and 27 control participants were included. Donors were older (42.8 vs 38.8 years) and had a higher baseline creatinine (103 vs 72 umol/L). All other parameters were the same. The percent change between fasting and nonfasting creatinine was smaller in living kidney donors than in control participants (0.12% vs 0.21% change, P = .04). Values of sodium, albumin, and osmolarity were not different between groups. Time from donation did not influence results. CONCLUSIONS: Living kidney donors practicing a day fast showed a different pattern regarding the change in creatinine levels. This pattern cannot be considered hazardous for living kidney donors. The emotional wellbeing of living kidney donors is of utmost importance, and this first report of the safety of a 24-hour fast is reassuring. These findings may be of interest to other religious groups, for example, the Muslim community which observes Ramadan.

The impact of preoperative vitamin administration on skeletal status following sleeve gastrectomy in young and middle-aged women: a randomized controlled trial.

BACKGROUND: The appropriate strategies to minimize skeletal deterioration following bariatric surgeries are inconclusive. This randomized controlled trial evaluated the effect of preoperative vitamin supplementation on bone mineral density (BMD) and biochemical parameters in females post-sleeve gastrectomy (SG). METHODS: Participants were randomized to a 2-month preoperative treatment with a multivitamin and vitamin D 4000 IU/d (intervention arm) or 1200 IU/d (control arm). Preoperative and 12-month postoperative follow-up evaluations included anthropometrics, biochemical parameters, and dual energy X-ray absorptiometry (DEXA). RESULTS: Sixty-two females (median age 29.7 years and median BMI 43.4 kg/m2) were recruited, 87% completed the 12-month follow-up. For the intervention and control arms, significant and similar reductions at 12-months post-surgery were observed in BMD of the hip (-6.8 ± 3.7% vs. -6.0 ± 3.6%; P = 0.646) and of the femoral neck (-7.1 ± 5.8% vs. -7.2 ± 5.5%; P = 0.973). For the intervention compared to the control arm, the 25 hydroxyvitamin D (25(OH)D) increment was greater after 2 months treatment, and vitamin D deficiency rates were lower at 3 and 6-months follow-up (P < 0.016). However, at 12-months postoperative, 25(OH)D values and vitamin D deficiency were comparable between the arms (P > 0.339). Predictors for BMD decline in the total hip were the percentage of excess weight-loss, age>50 years, and lower initial BMI (P ≤ 0.003). CONCLUSIONS: SG was associated with a significant decline in BMD of the hip and femoral neck in young and middle-aged women, and was unaffected by preoperative vitamin D supplementation. Females who are peri-menopausal or with greater postoperative weight-loss should be particularly followed for BMD decline.

Splenic Vein as an Autologous Graft in Traumatic SMV Injuries: A Missed Valuable Alternative.

Traumatic superior mesenteric artery (SMA) and vein (SMV) injuries are rare but often lethal. The ideal management options of traumatic SMV injury are still controversial. Management options include venous repair and ligation. Splenic vein turndown procedure (SVTP) is a rare procedure that has been described in only 6 cases in the literature. Here, we reviewed the literature on the usage of the splenic vein turndown procedure (SVTP) as an alternative option in patients with traumatic SMV injury. METHODS: We performed a narrative review for the available literature on the usage of the splenic vein as an autologous graft in the management of the SMV injury. We included all studies of SVTP in traumatic SMV injuries only. RESULTS: We included only 5 studies. In total, 7 patients underwent SVTP. Five patients presented with a penetrating abdominal vascular trauma (AVT) and 2 patients with a blunt AVT. The advantages of the SVTP include no need for additional incisions to harvest potential autologous grafts, minimally increased operative time, and 1 less anastomotic site compared to other conduit options. CONCLUSIONS: In cases of traumatic SMV injuries with associated splenic or pancreatic injuries that need distal pancreatosplenectomy, surgeons may consider SVTP as an ideal management option rather than primary repair or ligation.

Food Addiction and Binge Eating During One Year Following Sleeve Gastrectomy: Prevalence and Implications for Postoperative Outcomes.

BACKGROUND: Food addiction and binge eating are common among individuals with obesity. However, a paucity of studies prospectively examined the prevalence and implications of food addiction before and post-bariatric surgery. We aimed to examine the prevalence of food addiction and binge eating before and after sleeve gastrectomy (SG) and to assess their associations with behavioral and weight loss outcomes. METHODS: We followed at 3 (M3), 6 (M6), and 12 (M12) months postoperative, 54 women who underwent SG. Data collected including anthropometrics, nutritional intake, food tolerance, and physical activity measures. The Yale Food Addiction Scale and the Binge Eating Scale were used to characterize food addiction and binge eating, respectively. RESULTS: The mean baseline age and BMI were 32.1 ± 11.1 years and 44.9 ± 4.9 kg/m2, respectively. Pre-surgery, food addiction, and binge eating were identified in 40.7% and 48.1% of patients, respectively. The prevalence of food addiction decreased significantly up to M6, but increased to 29.3% at M12. The prevalence of binge eating decreased significantly through the follow-up up to 17.4% at M12. Those who met criteria for food addiction at M12 achieved significantly lower excess weight loss at M12 compared with those not meeting this criterion (P = 0.005). Food addiction scores at M12 negatively correlated with weekly physical activity (r = - 0.559; P < 0.001) and food tolerance scores (r = - 0.428; P = 0.005). CONCLUSIONS: The reduction in food addiction observed at M6 was not maintained at M12. Food addiction at M12 was associated with poorer weight loss, eating, and lifestyle behaviors. Clinical practice should focus on the psychological aspects associated with obesity.

Prognosis and Treatment of Liver Transplant Recipients in the COVID-19 Era: A Literature Review.

Liver transplantation during the COVID-19 pandemic is challenging. Both donor and recipient issues can be influenced by the risks attributed to the pandemic. Allocation policy may need to be modified and criteria may be influenced by local infection rates and availability of medical facilities. Modifying immunosuppression (IS) protocols is controversial and is not evidence-based. In this study, we review the published literature on liver transplant recipients who were infected with COVID-19. A literature review was performed using PubMed, ScienceDirect, and WHO databases to identify relevant English-language articles published up to May 20, 2020. Fifteen articles reported 120 liver transplant recipients who were infected with COVID-19. Only 10 papers with 22 patients reported full encounter characteristics. Four papers reported 23, 17, 13, and 6 patients, respectively, but with minimal data. One paper reported the authors' own 39 patients' characteristics and demographics. The mean age was 58.2 years with 66% males. The most commonly reported presentations in descending order were fever (91%), cough (36.7%), shortness of breath (SOB) (31.8%), and diarrhea (31.8%). Liver transplant patients infected with COVID-19 were maintained on Tac (79%), mycophenolate (MMF) (48.4%), and Prednisone (29.6%) and were managed by reducing MMF in 14.3% of patients and reducing Tac in 14.3% of patients; 28.6% of patients needed ICU admission, 13.6% of patients had died, and the reported general population COVID-19 mortality rate was 3.4%. The clinical presentation of COVID-19 in liver transplant recipients may be different from the general population, with higher rates of severe disease, complications, and mortality.

Practical recommendations for kidney transplantation in the COVID-19 pandemic.

Kidney transplantation at the time of a global viral pandemic has become challenging in many aspects. Firstly, we must reassess deceased donor safety (for the recipient) especially in communities with a relatively high incidence of coronavirus disease 19 (COVID-19). With respect to elective live donors, if one decides to do them at all, similar considerations must be made that may impose undue hardship on the donor. Recipient selection is also problematic since there is clear evidence of a much higher morbidity and mortality from COVID-19 for patients older than 60 and those with comorbidities such as hypertension, diabetes, obesity and lung disease. Unfortunately, many, if not most of dialysis patients fit that mold. We may and indeed must reassess our allocation policies, but this must be done based on data rather than conjecture. Follow-up routines must be re-engineered to minimize patient travel and exposure. Reliance on technology and telemedicine is paramount. Making this technology available to patients is extremely important. Modifying or changing immunosuppression protocols is controversial and not based on clinical studies. Nevertheless, we should reassess the need for induction therapy across the board for ordinary patients and the more liberal use of mammalian target of rapamycin inhibitors in transplant patients with proven infection.

Gastric goblet cell carcinoma concurrent with a neuroendocrine tumor.

Goblet cell carcinoma, a tumor that is assumed to originate from crypt base stem cells, is a distinct type of tumor, that occurs typically in the appendix, however, extra-appendiceal locations were also described in few cases. We herein present a unique case of a 48-year-old male with a diagnosis of primary gastric Goblet cell carcinoma that was initially discovered at the time of an endoscopy performed to evaluate an unremitting abdominal pain that was accompanied by remarkable weight loss; four polypoid fragments of the gastric mucosa were sent for histopathologic examination which showed a moderately differentiated goblet cell carcinoma in addition to classical neuroendocrine tumor. Later, laparoscopic D2 total gastrectomy with appendectomy were performed and confirmed the previously mentioned findings along with a normal histopathology of the appendix.
