Outcomes in transcatheter aortic valve replacement (TAVR) patients requiring red blood cell transfusion: A nationwide perspective.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) can be complicated by anemia due to periprocedural bleeding, hemolysis, vascular events, or significant bleeding associated with antiplatelet therapy. OBJECTIVE: We used the National Inpatient Sample (NIS) database to study the outcomes of patients who underwent TAVR and developed significant anemia requiring red blood cell (RBC) transfusion. METHODS: This is a retrospective cohort study utilizing the NIS database from 2016 to 2017. We identified patients who underwent TAVR and required RBC transfusion using ICD-10 and PCS-10 codes. The primary outcome was all-cause inpatient mortality, and the secondary outcomes were the cost of hospitalization and length of stay (LOS). Student t-test, Chi-square, and ANOVA were utilized for statistical analysis where applicable. Multivariate logistic regression was used to adjust for potential confounders. STATA 15.0 was utilized for data analysis. RESULTS: A total of 18,325 patients underwent TAVR in 2016-2017. Among them, 6.7 % of patients required RBC transfusion. Patients were relatively older in the transfusion group (81 yrs vs 79 yrs; p < 0.001). The mean cost of hospitalization was higher in the transfusion group (283,153 USD vs 208,939 USD; p < 0.001). The mean length of stay (LOS) was higher in the transfusion group (9.0 days vs 4.3 days; p < 0.001). Patients in the transfusion group had higher inpatient all-cause mortality compared to patients without transfusion (6.1 % vs 1.3 %; odds ratio 4.94; p < 0.001, 95 % CI 3.7-6.4). Inpatient mortality and LOS didn't differ by race or sex in the transfusion group. All-cause mortality, LOS, and cost of hospitalization were independently increased by transfusion after adjusting for potential confounders i.e. sex, race, hospital teaching status, hospital region, heart block, pacemaker, arrhythmias, heart failure, diabetes, pulmonary hypertension, CKD, and others using multivariate logistic regression. CONCLUSION: In patients undergoing TAVR, blood transfusion was associated with adverse outcomes including increased mortality, length of stay, and cost of hospitalization. The role of careful patient selection, judicious use of antiplatelets, anticoagulants, and pre-procedural optimization of anemia needs further investigation to optimize patient outcomes.

Comparative Study of Treatment Outcome with Tenofovir Alafenamide and Entecavir in Patients with HBV Related Acute on Chronic Liver Failure.

Major causes of acute insult in Hepatitis B virus related acute on chronic liver failure in the Asian region are reactivation of Hepatitis B virus and super infection with hepatitis A and E virus (ACLF). Anti viral therapy should be started as soon as possible in the ACLF patients at presentation while waiting for confirmation by HBV DNA level. This randomized controlled trial was carried out at the Department of Hepatology, BSMMU, Bangladesh from September 2019 to august 2020 with Hepatitis B virus related ACLF patient. This trial was conducted among twenty seven HBV acute on chronic liver failure patient to compare Child Turcotte pugh (CTP) score, Model for end stage liver disease (MELD) score, Asia Pacific Association for study of Liver (APASL) ACLF Research consortium (AARC) score, survival of the patients and HBV DNA level at 3 months with antiviral therapy between tenofovir alafenamide (25mg) and entecavir (0.5mg) group. CTP score, MELD score and AARC score were significantly (p<0.05) decline from baseline to all subsequent follow-up at 1st (at 7 days), 2nd (at 14 days), 3rd (at 30 days) and 4th (at 90 days) in each group but non significant (p>0.05) difference occurred between two group. All twenty seven patients had detectable HBV DNA level at pre-treatment and all survived patients became undectable at 4th, 90 days follow-up. Total 10 patients (37.07%) were survived at 90 days follow-up, out of them seven patients (70.0%) were in tenofovir alafenamide group and three patients (30.0%) were in entecavir group which was statistically significant (p<0.05) in between two group. Hepatic encephalopathy and hepatorenal syndrome were most common causes of death in both groups. Both drugs tenofovir alafenamide and entecavir significantly improves liver functions but the former one is superior regarding survival.

Clinico-epidemiological Characteristics of the Physician Affected with Covid-19.

Coronavirus disease 2019 (Covid-19) disease have been associated with significant mortality amongst doctors globally including Bangladesh. To delineate the clinico-epidemiological characteristics of the physician affected with Covid-19 was the objective of the study. This cross-sectional 'Facebook' based survey was conducted in the period of August 2020 to September 2020. Snowball sampling methods was followed. A total of 151 physicians affected with Covid-19 participated in this survey. Self-reported perceived severity scale (zero meaning not severe at all and ten denoting the most severe) was used. Collected data were analyzed by SPSS 25.0. Among the participants, the majority were male, 98(64.9%). The most prevalent affected age groups were 24-35 years 131(86.8%). Approximately 45.0% worked in COVID dedicated hospital. Entry-level physicians (Medical Officer or Assistant Surgeon) were the most affected 117(94.4%). One-third of the physicians had at least the one co-morbidity. Bronchial asthma, obesity and diabetes were the most frequent. Predominate symptoms of the infection were fever 94(62.3%), cough 94(62.3%) and myalgia 92(60.9%). Half of the participants had sore throat, anosmia, gastro-intestinal symptoms and one-third of the patients developed dyspnea. Perceived severity of the symptoms ranged between 2 and 6. The pattern of drug use to prevent the Covid-19 showed no uniformity. However, intake of Zinc, Vitamin C, Vitamin D, antihistamine and Ivermectin was found in 74.8%, 67.5%, 41.7%, 49.0% and 37.7% respectively. As the current pandemic continues to evolve, physicians must be equipped with appropriate knowledge, skills and must be cautious on the prevention measures against Covid-19.

Subarachnoid Hemorrhage as a Presentation of Hemophilia: A Case Report.

A young boy presented with features of non-traumatic Subarachnoid hemorrhage (SAH) with hematemesis and melaena. He has had past history of prolonged bleeding following cut injury even requiring blood transfusion after circumcision. On examination, he was found confused, severely anemic, with presence of neck rigidity and painful swelling of right knee joint. But no positive family history was found. Non-contrast CT scan showed SAH. Cerebral angiography showed no aneurysm but knee joint had features of hemarthrosis. He was resuscitated and hemophilia was diagnosed on the basis of clinical suspicion of clotting factor assay. Specific treatment started in collaboration with Department of Hematology. This is a rare presentation of hemophilia as well as very uncommon cause of non-traumatic non-aneurysmal SAH.

Serum Lipid Profile and Its Association with Newly Diagnosed Hypertensive Patients in Bangladesh.

Clustering of hypertension, dyslipidemia, and other metabolic abnormalities is increasing the burden of non-communicable diseases, especially cardiovascular disease. The objective of this study was to explore the pattern of lipid profiles in newly diagnosed hypertensive patients attending Shaheed Mansur Ali Medical College, Dhaka, Bangladesh from August 2020 to December 2020. A total of 59 newly diagnosed hypertensive patients were studied through a cross-sectional approach. Prior to the study, ethical clearance was ensured, and informed written consent was obtained. A pre-structured questionnaire was used for data collection. Collected data were analyzed using SPSS 24.0 version. Slight male preponderance (54.2%) was observed along with an average age of 45 years among studied patients. Raised levels of total cholesterol (TC), triglyceride (TG), and low-density lipoprotein (LDL) were observed in 91.5%, 98.3%, and 88.1% of patients accordingly. Low level of high-density lipoprotein (HDL) was observed in 47.5% of the patients. Mean TC, TG, LDL, HDL were 286.11±347.37, 311.74±122.76, 163.27±33.67 and 38.29±6.66 mg/dl, respectively. Almost all patients were obese. There is no correlation between the serum lipid profile and blood pressure of the patients. Dyslipidemia was highly prevalent among newly diagnosed hypertensive patients.

Mayer-Rokitansky-Kuster-Hauser Syndrome Presented with Diabetes Mellitus and Primary Amenorrhea: A Case Report.

Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a rare congenital disorder that affects the female reproductive system and is characterized by an underdeveloped or absent uterus and vagina. A 17-year-old unmarried female was admitted into the Department of Endocrinology, Mymensingh Medical College Hospital, Bangladesh in November 2023 for evaluation of primary amenorrhea and poorly controlled diabetes mellitus. She was the 5th issue of non-consanguineous marriage delivered at term by normal vaginal delivery. Her growth pattern and developmental milestones were normal. She had no history of galactorrhea, chronic or cyclic pelvic pain, thyroid dysfunction, excessive exercise, psychiatric illness, or drug abuse. There was no history of such type of illness in her family. She was diagnosed with diabetes mellitus two years back without classic symptoms, and at that time, her blood glucose was 22 mmol/L. She was prescribed metformin and gliclazide. She had no history of hypoglycemia, hyperglycemic crises, or hospital admission. On examination, her body build and nutritional status were normal. Anemia, jaundice, edema, dehydration, lymphadenopathy, acne, hirsutism, acanthosis nigricans, abdominal striae and vitiligo were absent. Her blood pressure was 110/70 without the postural drop, thyroid gland was not enlarged, anthropometric measurements were normal and BMI was 18.4 kg/m2. Her tanner stage was P5 & B4. Genital examination revealed normal female external genitalia, and a blind vaginal pouch was found. Other systemic examinations revealed no abnormality. On laboratory reports, her blood glucose was uncontrolled (HbA1c-10.2%) with glycosuria. Thyroid function test and gonadal hormones were normal. Ultrasonogram of the abdomen revealed uterus, cervix, and upper part of the vagina are absent, and an ectopic left kidney.

Consensus-Based Guidelines for Acute Myeloid Leukemia Management in Gulf Cooperation Council Countries: Addressing Unmet Regional Needs and the Changing AML Landscape.

PURPOSE: AML is a heterogeneous hematologic malignancy. Region-specific recommendations for AML management can enhance patient outcomes. This article aimed to develop recommendations for the Gulf Cooperation Council (GCC) countries. METHODS: Ten AML panel members from Kuwait, Oman, Qatar, and the United Arab Emirates (KOQU) participated in a modified two-round Delphi process. The panel first identified the unmet regional needs and finalized a list of core variables. Next, they voted on iterative statements drawn from international recommendations and provided feedback via a questionnaire. Consensus voting ≤70% was discussed, and additional clinical decision making statements were suggested. At round closure, a consensus vote took place on revised statements. RESULTS: The panel reached ≥97.8% consensus on AML management. The panel agreed to use international risk stratification categories for personalized treatment of AML. The presence of ≥10% blasts for recurrent genetic abnormalities was required for a diagnosis of AML. Key consensus was reached for different treatment stages. The panel noted that older patients pose a challenge because of poor cytogenetics and genetic anomalies and require different treatment approaches. The panel recommended venetoclax-hypomethylating agents; fludarabine, cytarabine, idarubicin, and granulocyte colony-stimulating factor; and targeted therapy for AML relapsed/refractory disease. Supportive care is considered on the basis of prevailing organisms and drug resistance. CONCLUSION: The GCC KOQU's consensus-based recommendations for managing AML include an evidence-based and region-specific framework.

PD-L1 and PD-L2 Expression in Different Tumor Stages and Types of Malignant Salivary Gland Neoplasms: A Single-center Experience.

There is a limited amount of data on the role of programmed cell death ligand (PD-L) -1 and PD-L2 in salivary gland carcinomas. We aimed to evaluate the prognostic value of PD-L1 and PD-L2 expressions, which are closely related to immune mechanisms, with respect to salivary gland tumor types and stages. Data from patients with salivary gland masses surgically removed between 2006 and 2021, diagnosed with a malignant salivary gland neoplasm, were retrospectively analyzed. Immunoreactivity for PD-L1 and PD-L2 was performed on resection materials. The mean age of 90 patients was 52.1±18.8 and 46.7% were male. Overall, 55.6% of patients were diagnosed with adenoid cystic carcinoma (ACC), 23.3% with mucoepidermoid carcinoma (MEC), 16.7% with acinic cell carcinoma (AciCC), 3.3% with ductal carcinoma (DC), and 1 patient with pleomorphic adenoma ex carcinoma (PA-ex-CA). In all, 52% of ACC, 12% of AciCC, 24% of MEC, and 12% of DC cases were at stage IV. The tumor diameter, frequencies of lymphovascular invasion, metastasis, positive surgical margin, recurrence, and mortality rates of patients at stages III and IV were significantly larger than those at stages I and II (P<0.05). The percentages of tumor cell score (TCS) and immune cell score (ICS) for PD-L1 were significantly higher among patients with MEC compared with those with other types of tumors (P=0.0011). However, the percentages of combined score (CS) for PD-L1 and tumor cell score for PD-L2 were comparable among tumor types (P>0.05). No significant difference was found in these scores for PD-L1 between tumor stages (P>0.05), but for PD-L2, all patients at stage I had TCS <1% for PD-L2, while all patients at stages II and III, and 92% of patients at stage IV had TCS ≥1% (P<0.0001). High expression of PD-L1 was mostly observed in MEC cases (P=0.0016), while all patients with AciCC had a low PD-L1 expression level (P=0.0206). The mean tumor diameter, rate of lymphovascular invasion, perineural invasion, metastasis, positive surgical margin, recurrence, type of treatment, mortality, and TILs ratio did not differ significantly according to PD-L1 expression level (P>0.05). The percentage of tumor-infiltrating lymphocytes was comparable among negative and positive PD-L1 scores according to both 1% and 5% threshold values (P>0.05). High PD-L1 expression is rare in AciCC, while PD-L1 expression is high in MEC. Our findings underline the importance of future screening for PD-L1 and PD-L2 before patients undergoing immunotherapies in all salivary gland tumors.

Outcomes of extracorporeal blood purification with oXiris® membrane in critically ill patients: A systematic review and meta-analysis.

PURPOSE: To evaluate the efficacy of the novel oXiris® membrane in critically ill adult patients. METHODS: We systematically searched MEDLINE, EMBASE, and CENTRAL from inception to 01/06/2023 for relevant randomised controlled trials (RCTs) and non-randomised studies of intervention (NRSI). The primary outcome was overall mortality. Random effect meta-analyses were conducted in RevMan 5.4.1. Study quality was evaluated using Cochrane's risk of bias tool. (PROSPERO: CRD42023389198). RESULTS: Ten studies (2 RCTs and 8 NRSIs) with 481 patients were included. None had low risk of bias. Treatment using oXiris® was associated with reduced overall mortality (RR 0.78, 95%CI 0.62-0.98; p = 0.03; 6 NRSI). One RCT reported 28-day mortality, finding no significant difference between groups. Besides, pooled NRSIs results showed significant reductions in SOFA scores, norepinephrine dosage, and several inflammatory biomarkers (C-reactive protein [CRP], lactate, and interleukin-6 [IL-6]) post oXiris® treatment. However, other clinical outcomes (ICU and hospital length of stay, mechanical ventilation duration) were similar between groups. CONCLUSION: In critically ill patients, the use of oXiris® membrane was associated with reduced overall mortality, norepinephrine dosage, CRP, IL-6, lactate levels, along with improved organ function. However, the certainty of evidence was very low, necessitating high-quality RCTs to further evaluate its efficacy in this population.

Early experience of using regional citrate anticoagulation for continuous renal replacement therapy in critically ill patients in a resource-limited setting.

AIM: Despite the superiority of regional citrate anticoagulation (RCA) in continuous renal replacement therapy (CRRT), its application is limited in resource-limited settings. We aim to explore the cost and safety of RCA for CRRT in critically ill patients, compared to usual care. METHODS: This prospective observational study included patients requiring CRRT in a tertiary intensive care unit (ICU) from February 2022 to January 2023. They were classified to either the RCA or usual care groups based on the anticoagulation technique chosen by the treating physician, considering contraindications. The CRRT prescription follows the institutional protocol. All relevant data were obtained from the ICU CRRT-RCA charts and electronic medical records. A cost analysis was performed. RESULTS: A total of 54 patients (27 per group) were included, with no demographic differences. Sequential Organ Failure Assessment score and lactate levels were significantly higher in the usual care group. The number of filters used were comparable (p = .108). The median filter duration in the RCA group was numerically longer (35.00 [15.50-56.00] vs. 23.00 [17.00-29.00] h), but not statistically significant (p = .253). The duration of mechanical ventilation, vasopressor requirement, and mortality were similar, but the RCA group had a significantly longer ICU stay. The rate of adverse events was similar, with four severe metabolic alkalosis cases in the RCA group. The RCA group had higher total cost per patient per day (USD 611 vs. 408; p = .013). CONCLUSION: In this resource-limited setting, RCA for CRRT appeared safe and had clinically longer filter lifespan compared with usual care, albeit the increased cost.

Prolonged vs Intermittent Infusions of ß-Lactam Antibiotics in Adults With Sepsis or Septic Shock: A Systematic Review and Meta-Analysis.

Importance: There is uncertainty about whether prolonged infusions of ß-lactam antibiotics improve clinically important outcomes in critically ill adults with sepsis or septic shock. Objective: To determine whether prolonged ß-lactam antibiotic infusions are associated with a reduced risk of death in critically ill adults with sepsis or septic shock compared with intermittent infusions. Data Sources: The primary search was conducted with MEDLINE (via PubMed), CINAHL, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov from inception to May 2, 2024. Study Selection: Randomized clinical trials comparing prolonged (continuous or extended) and intermittent infusions of ß-lactam antibiotics in critically ill adults with sepsis or septic shock. Data Extraction and Synthesis: Data extraction and risk of bias were assessed independently by 2 reviewers. Certainty of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation approach. A bayesian framework was used as the primary analysis approach and a frequentist framework as the secondary approach. Main Outcomes and Measures: The primary outcome was all-cause 90-day mortality. Secondary outcomes included intensive care unit (ICU) mortality and clinical cure. Results: From 18 eligible randomized clinical trials that included 9108 critically ill adults with sepsis or septic shock (median age, 54 years; IQR, 48-57; 5961 men [65%]), 17 trials (9014 participants) contributed data to the primary outcome. The pooled estimated risk ratio for all-cause 90-day mortality for prolonged infusions of ß-lactam antibiotics compared with intermittent infusions was 0.86 (95% credible interval, 0.72-0.98; I2 = 21.5%; high certainty), with a 99.1% posterior probability that prolonged infusions were associated with lower 90-day mortality. Prolonged infusion of ß-lactam antibiotics was associated with a reduced risk of intensive care unit mortality (risk ratio, 0.84; 95% credible interval, 0.70-0.97; high certainty) and an increase in clinical cure (risk ratio, 1.16; 95% credible interval, 1.07-1.31; moderate certainty). Conclusions and Relevance: Among adults in the intensive care unit who had sepsis or septic shock, the use of prolonged ß-lactam antibiotic infusions was associated with a reduced risk of 90-day mortality compared with intermittent infusions. The current evidence presents a high degree of certainty for clinicians to consider prolonged infusions as a standard of care in the management of sepsis and septic shock.

A Novel Cyclin-Dependent Kinase 13 Variant and Unusual Association of Situs Inversus Partialis in a Child From Bahrain: A Case Report and Literature Review.

Cyclin-dependent kinase 13 (CDK13)-related disorder is a rare autosomal dominant disease caused by pathogenic variants in the CDK13 gene. This disorder was found to be related to several clinical features, including structural cardiac anomalies, developmental delay, anomalies of the corpus callosum, and a variety of facial dysmorphisms. In addition, feeding difficulties and neonatal hypotonia might also present. The diagnosis of this disorder is based on molecular genetic testing to detect the causative pathogenic variants. Here, we report a case of a one-year-old girl from Yemen, residing in Bahrain, with a CDK13-related disorder who was found to have an unusual association of abdominal situs inversus along with multiple structural cardiac anomalies, including atrial septal defect, ventricular septal defect, patent ductus arteriosus, interrupted inferior vena cava, bilateral superior vena cava, mild coarctation of the aorta, dilated coronary sinuses, and mild regurgitation in the tricuspid valve. Moreover, facial dysmorphism including medial epicanthal folds, posteriorly rotated ears, and a depressed nasal bridge was also noted. Further assessment showed a delay in reaching developmental milestones, including speech and motor delay. The patient also presented with recurrent episodes of upper respiratory tract infections, acute bronchiolitis, and lobar pneumonia which required admission to the intensive care unit and ventilation. The last infection episode was at the age of one year. Thereafter, the patient underwent cardiac repair of the ventricular septal defect followed by no more infection episodes until the age of one year and two months. The diagnosis of CDK13 was confirmed by a whole exome sequencing test which demonstrated a novel missense variant in exon 14 of the CDK13 gene as a variant of uncertain significance in a heterozygous state.

Factors affecting severity and prognosis of traumatic brain injury among Bangladeshi patients: An institution based cross-sectional study.

OBJECTIVE: Traumatic brain injury (TBI) proves to be an obstacle for Bangladeshi patients due to the lack of facilities and specialist doctors in regional sections of the country. This study aimed to record different attributes of Bangladeshi TBI patients over a year i.e., their injury characteristics, treatments received and understand their impacts on the severity of TBI. METHOD: This cross-sectional study was carried out among 280 TBI patients treated in a tertiary care hospital in Dhaka. The physicians determined TBI's severity and prognosis as per the Glasgow Coma Scale (GCS) and Glasgow Outcome Score (GOS) respectively. RESULTS: Most TBI patients were male (76.1%) and aged between 18 and 50 years (52.2%), as in previous studies in South Asian countries. However, the prevalence of TBI due to road traffic accidents (RTAs) was much higher (67.9%) than in the earlier studies in South Asia. Additionally, more patients suffered from severe TBI (29.3%) and moderate TBI (35.7%), and a higher percentage of patients went through surgery (56.8%) compared to previous studies. A significant association of demographic (residence) and clinical characteristics (consciousness after injury, CT scan findings and treatment type) with the severity of TBI was found in bivariate analysis. It also revealed the significant dependence of clinical characteristics (TBI etiology, post-injury consciousness, treatment type and TBI severity) on TBI prognosis. Multivariate analysis showed that patients who were unconscious after TBI and with evident brain injury observed in CT scans have a substantially higher risk of having moderate or severe TBI than mild TBI. Moreover, patients with TBI due to RTAs or falls, evident brain injury in CT scans, post-surgical seizure, and moderate or severe TBI have a significantly higher risk of getting a more unfavorable TBI prognosis than moderate disability. CONCLUSIONS: In this study, RTAs were found to be the major cause of TBI. Additionally, some variables were identified as possible determinants of TBI severity and prognosis among Bangladeshi patients. The correlation of these variables with TBI should be further studied with the hopes that steps will be taken to reduce TBI incidents and improve its management to reduce the overall burden.

Quality Indicators in Adult Critical Care Medicine.

Quality indicators are increasingly used in the intensive care unit (ICU) to compare and improve the quality of delivered healthcare. Numerous indicators have been developed and are related to multiple domains, most importantly patient safety, care timeliness and effectiveness, staff well-being, and patient/family-centered outcomes and satisfaction. In this review, we describe pertinent ICU quality indicators that are related to organizational structure (such as the availability of an intensivist 24/7 and the nurse-to-patient ratio), processes of care (such as ventilator care bundle), and outcomes (such as ICU-acquired infections and standardized mortality rate). We also present an example of a quality improvement project in an ICU indicating the steps taken to attain the desired changes in quality measures.

Statistical analysis plan for the replacing protein via enteral nutrition in a stepwise approach in critically ill patients (REPLENISH) randomized clinical trial.

BACKGROUND: The optimal amount and timing of protein intake in critically ill patients are unknown. REPLENISH (Replacing Protein via Enteral Nutrition in a Stepwise Approach in Critically Ill Patients) trial evaluates whether supplemental enteral protein added to standard enteral nutrition to achieve a high amount of enteral protein given from ICU day five until ICU discharge or ICU day 90 as compared to no supplemental enteral protein to achieve a moderate amount of enteral protein would reduce all-cause 90-day mortality in adult critically ill mechanically ventilated patients. METHODS: In this multicenter randomized trial, critically ill patients will be randomized to receive supplemental enteral protein (1.2 g/kg/day) added to standard enteral nutrition to achieve a high amount of enteral protein (range of 2-2.4 g/kg/day) or no supplemental enteral protein to achieve a moderate amount of enteral protein (0.8-1.2 g/kg/day). The primary outcome is 90-day all-cause mortality; other outcomes include functional and health-related quality-of-life assessments at 90 days. The study sample size of 2502 patients will have 80% power to detect a 5% absolute risk reduction in 90-day mortality from 30 to 25%. Consistent with international guidelines, this statistical analysis plan specifies the methods for evaluating primary and secondary outcomes and subgroups. Applying this statistical analysis plan to the REPLENISH trial will facilitate unbiased analyses of clinical data. CONCLUSION: Ethics approval was obtained from the institutional review board, Ministry of National Guard Health Affairs, Riyadh, Saudi Arabia (RC19/414/R). Approvals were also obtained from the institutional review boards of each participating institution. Our findings will be disseminated in an international peer-reviewed journal and presented at relevant conferences and meetings. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04475666 .

Satisfaction and Quality of Life in Patients Who Underwent Post Massive Weight Loss Body Contouring Procedures: A Tertiary Center Experience in Bahrain.

Background: Incidence of body contouring surgeries (BCS) rose significantly to overcome problems resulted from post-Bariatric Surgery (BS). We aimed to evaluate satisfaction level and quality of life (QOL) in patients' post-BCS. Methods: In this retrospective prospective study, patients who underwent BCS in Plastic Surgery Department, Salmaniya Medical Complex, Bahrain, in 2017-2018, were enrolled. Demographic and anthropometric data were collected. BS-group's QOL and satisfaction level were assessed using a questionnaire. Results: Of 929 plastic surgery admissions, 316 (34%) were for BCS (249 patients). Fifty-eight (28%) patients underwent 82 BS were recruited, mostly females (n=42, 72.4%). The mean age was 37.4±9.6 years. Excess abdominal skin was the most area of concern (n=50, 86.2%). Median pre-BCS body mass index was 26.9 (interquartile range: 25.6-29.8) kg/m2. Most patients were overweight (n=26, 44.8%). Abdominoplasty was the commonest BCS (n=172, 50.6%). This was also the case in 82 BCS in post-BS group (n=38, 46.3%). In post-BS group, post-operative complications were noted in 25/82 (30.5%) patients with wound problems being the most frequent (n=14, 17.1%). Most patients rated their experience as better in all questionnaire domains and most (n=45, 54.9%) rated their satisfaction level as excellent. Older age gave better overall satisfaction (P<0.001) while employed patients had better overall QOL (P=0.012) and self-confidence (P=0.048). Females had better satisfaction with body appearance (P<0.001) while those underwent abdominoplasty or breast surgeries had lower physical activity (P=0.042). Conclusion: This study showed improvement in patient's QOL post-BCS with excellent overall satisfaction, findings that could be affected by age, sex, and occupation.

Practice and Predictors of Do-Not-Resuscitate Orders in a Tertiary-Care Intensive Care Unit in Saudi Arabia.

Introduction: The objective of this study was to describe Do-Not-Resuscitate (DNR) practices in a tertiary-care intensive care unit (ICU) in Saudi Arabia, and determine the predictors and outcomes of patients who had DNR orders. Methods: This retrospective cohort study was based on a prospectively collected database for a medical-surgicalIntensive CareDepartment in a tertiary-care center in Riyadh, Saudi Arabia (1999-2017). We compared patients who had DNR orders during the ICU stay with those with "full code." The primary outcome was hospital mortality. The secondary outcomes included ICU mortality, tracheostomy, duration of mechanical ventilation, and length of stay in the ICU and hospital. Results: Among 24790 patients admitted to the ICU over the 19-year study period, 3217 (13%) had DNR orders during the ICU stay. Compared to patients with "full code," patients with DNR orders were older (median 67 years [Q1, Q3: 55, 76] versus 57 years [Q1, Q3: 33, 71], p < 0.0001), were more likely to be females (43% versus 38%, p < 0.0001), had worse premorbid functional status (WHO performance status scores 4-5: 606[18.9%] versus 1894[8.8%], p < 0.0001), higher prevalence of comorbid conditions, and higher APACHE II score (median 28 [Q1, Q3: 23, 34] versus 19 [Q1, Q3: 13, 25], p < 0.0001) and were more likely to be mechanically ventilated (83% versus 55%, p < 0.0001). Patients had DNR orders were more likely to die in the ICU (67.8% versus 8.5%, p < 0.0001) and hospital (82.4% versus 18.1%, p < 0.0001). On multivariable logistic regression analysis, the following were associated with an increased likelihood of DNR status: increasing age (odds ratio (OR) 1.01, 95% confidence interval (CI) 1.01-1.02), higher APACHE II score (OR 1.09, 95% CI 1.08-1.10), and worse WHO performance status score. Patients admitted in recent years (2012-2017 versus 2002-2005) were less likely to have DNR orders (OR 0.35, 95% CI 0.32-0.39, p < 0.0001). Patients with DNR orders had higher ICU mortality, more tracheostomies, longer duration of mechanical ventilation and length of ICU stay compared to patients with with "full code" but they had shorter length of hospital stay. Conclusion: In a tertiary-care hospital in Saudi Arabia, 13% of critically ill patients had DNR orders during ICU stay. This study identified several predictors of DNR orders, including the severity of illness and poor premorbid functional status.

Pediatric and adult liver transplantation in Bahrain: The experiences in a country with no available liver transplant facilities.

BACKGROUND: Liver transplantation (LT) is a life-saving procedure for patients with end-stage liver disease and has become the standard and most effective treatment method for these patients. There are many indications for LT that vary between countries and settings. The outcome of LT depends on the available facilities and surgical expertise, as well as the types of liver graft donors available. AIM: To assess the clinical characteristics of patients from Bahrain who underwent LT overseas, and analyze factors affecting their survival. METHODS: In this retrospective cohort study, we reviewed the medical records and overseas committee registry information of all pediatric and adult patients who were sent overseas to undergo LT by the Pediatric and Medical Departments of Salmaniya Medical Complex and Bahrain Defence Force Hospital via the Overseas Treatment Office, Ministry of Health, Kingdom of Bahrain, between 1997 and 2023. Demo graphic data, LT indication, donor-recipient relationship, overseas LT center, graft type, post-LT medications, and LT complications, were collected. Outcomes measured included the overall and 5-year LT survival rate. Fisher's exact, Pearson χ2, and Mann-Whitney U tests were used to compare the pediatric and the adults' group in terms of clinical characteristics, donor-recipient relationship, medication, complications, and outcome. Survival analysis was estimated via the Kaplan-Meier's method. Univariate and multivariate analyses were used to detect predictors of survival. RESULTS: Of the 208 eligible patients, 170 (81.7%) were sent overseas to undergo LT while 38 (18.3%) remained on the waiting list. Of the 170 patients, 167 (80.3%) underwent LT and were included in the study. The majority of the patients were Bahraini (91.0%), and most were males (57.5%). One-hundred-and-twenty (71.8%) were adults and 47 (28.3%) were children. The median age at transplant was 50.0 [interquartile range (IQR): 14.9-58.4] years. The main indication for pediatric LT was biliary atresia (31.9%), while that of adult LT was hepatitis C-related cirrhosis (35.0%). Six (3.6%) patients required re-transplantation. Most patients received a living-related liver graft (82%). Pediatric patients received more living and related grafts than adults (P = 0.038 and P = 0.041, respectively), while adult patients received more cadaveric and unrelated grafts. Most patients required long-term immunosuppressive therapy after LT (94.7%), of which tacrolimus was the most prescribed (84.0%), followed by prednisolone (50.7%), which was prescribed more frequently for pediatric patients (P = 0.001). Most patients developed complications (62.4%) with infectious episodes being the most common (38.9%), followed by biliary stricture (19.5%). Tonsilitis and sepsis (n = 12, 8.1% for each) were the most frequent infections. Pediatric patients experienced higher rates of infection, rejection, and early poor graft function than adult patients (P < 0.001, P = 0.003, and P = 0.025, respectively). The median follow-up time was 6.5 (IQR: 2.6-10.6) years. The overall survival rate was 84.4%, the 5-year survival rate, 86.2%, and the mortality rate, 15.6%. Younger patients had significantly better odds of survival (P = 0.019) and patients who survived had significantly longer follow-up periods (P < 0.001). CONCLUSION: Patients with end-stage liver disease in Bahrain shared characteristics with those from other countries. Since LT facilities are not available, an overseas LT has offered them great hope.

An international multidisciplinary consensus on pediatric metabolic dysfunction-associated fatty liver disease.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is highly prevalent in children and adolescents, particularly those with obesity. NAFLD is considered a hepatic manifestation of the metabolic syndrome due to its close associations with abdominal obesity, insulin resistance, and atherogenic dyslipidemia. Experts have proposed an alternative terminology, metabolic dysfunction-associated fatty liver disease (MAFLD), to better reflect its pathophysiology. This study aimed to develop consensus statements and recommendations for pediatric MAFLD through collaboration among international experts. METHODS: A group of 65 experts from 35 countries and six continents, including pediatricians, hepatologists, and endocrinologists, participated in a consensus development process. The process encompassed various aspects of pediatric MAFLD, including epidemiology, mechanisms, screening, and management. FINDINGS: In round 1, we received 65 surveys from 35 countries and analyzed these results, which informed us that 73.3% of respondents agreed with 20 draft statements while 23.8% agreed somewhat. The mean percentage of agreement or somewhat agreement increased to 80.85% and 15.75%, respectively, in round 2. The final statements covered a wide range of topics related to epidemiology, pathophysiology, and strategies for screening and managing pediatric MAFLD. CONCLUSIONS: The consensus statements and recommendations developed by an international expert panel serve to optimize clinical outcomes and improve the quality of life for children and adolescents with MAFLD. These findings emphasize the need for standardized approaches in diagnosing and treating pediatric MAFLD.

Redox signalling in plant-nematode interactions: Insights into molecular crosstalk and defense mechanisms.

Plant-parasitic nematodes, specifically cyst nematodes (CNs) and root-knot nematodes (RKNs), pose significant threats to global agriculture, leading to substantial crop losses. Both CNs and RKNs induce permanent feeding sites in the root of their host plants, which then serve as their only source of nutrients throughout their lifecycle. Plants deploy reactive oxygen species (ROS) as a primary defense mechanism against nematode invasion. Notably, both CNs and RKNs have evolved sophisticated strategies to manipulate the host's redox environment to their advantage, with each employing distinct tactics to combat ROS. In this review, we have focused on the role of ROS and its scavenging network in interactions between host plants and CNs and RKNs. Overall, this review emphasizes the complex interplay between plant defense mechanism, redox signalling and nematode survival tactics, suggesting potential avenues for developing innovative nematode management strategies in agriculture.
