The Psychosocial and Spiritual Experiences of Patients with Advanced Incurable Illness in Bangladesh: A Cross-Sectional Observational Study.

CONTEXT: The psychosocial and spiritual needs of individuals with life-limiting conditions in low- or middle-income countries have not been well described. Understanding these needs is important to providing holistic palliative care. AIM: This study aims to better understand the psychosocial and spiritual needs and supports of patients with advanced, incurable illness in Bangladesh. SUBJECTS AND METHODS: Individuals with advanced incurable illnesses (advanced cancer and HIV/AIDS) from a wide geographical distribution across Bangladesh were interviewed about their health status, emotional and spiritual experiences with their illness, coping and support systems, and greatest needs and fears. RESULTS: We interviewed 221 individuals with incurable cancer (82%) or HIV/AIDS (18%). Self-reported health status was poor or very poor for 48%, and 44% reported feeling unhappy all of the time. The majority (61%) rated their current level of unhappiness as 10/10. Spouses (50%), children (15%), and parents (13%) were the most common caregivers. Money and medical care were equally the most common needs (46%). Participants' greatest fears were for the future of their children (38%), being in pain (29%), and dying (28%). CONCLUSIONS: There is a significant burden of psychosocial and spiritual concerns among patients with advanced incurable illness in Bangladesh, with sadness being very frequent and of high intensity. Family and friends provide significant emotional and practical support to patients who are seriously ill, but very few patients access any professional support for these concerns.

Outcomes of "diabetes-friendly" vs "diabetes-unfriendly" ß-blockers in older nursing home residents with diabetes after acute myocardial infarction.

AIMS: To assess whether nursing home (NH) residents with type 2 diabetes mellitus (T2D) preferentially received "T2D-friendly" (vs "T2D-unfriendly") ß-blockers after acute myocardial infarction (AMI), and to evaluate the comparative effects of the two groups of ß-blockers. MATERIALS AND METHODS: This new-user retrospective cohort study of NH residents with AMI from May 2007 to March 2010 used national data from the Minimum Data Set and Medicare system. T2D-friendly ß-blockers were those hypothesized to increase peripheral glucose uptake through vasodilation: carvedilol, nebivolol and labetalol. Primary outcomes were hospitalizations for hypoglycaemia and hyperglycaemia in the 90 days after AMI. Secondary outcomes were functional decline, death, all-cause re-hospitalization and fracture hospitalization. We compared outcomes using binomial and multinomial logistic regression models after propensity score matching. RESULTS: Of 2855 NH residents with T2D, 29% initiated a T2D-friendly ß-blocker vs 24% of 6098 without T2D (P < 0.001). For primary outcomes among residents with T2D, T2D-friendly vs T2D-unfriendly ß-blockers were associated with a reduction in hospitalized hyperglycaemia (odds ratio [OR] 0.45, 95% confidence interval [CI] 0.21-0.97), but unassociated with hypoglycaemia (OR 2.05, 95% CI 0.82-5.10). For secondary outcomes, T2D-friendly ß-blockers were associated with a greater rate of re-hospitalization (OR 1.26, 95% CI 1.01-1.57), but not death (OR 1.06, 95% CI 0.85-1.32), functional decline (OR 0.91, 95% CI 0.70-1.19), or fracture (OR 1.69, 95% CI 0.40-7.08). CONCLUSIONS: In older NH residents with T2D, T2D-friendly ß-blocker use was associated with a lower rate of hospitalization for hyperglycaemia, but a higher rate of all-cause re-hospitalization.

Association of Radiation-Induced Acute Esophagitis With Dosimetric Parameters of Oesophagus in Breast Carcinoma Patients Receiving Supraclavicular Nodal Irradiation.

INTRODUCTION: We conducted this investigation to ascertain the dosimetric properties such as the mean and maximum radiation dosage during radiotherapy as well as the extent of radiation exposure to the esophagus. These factors can potentially impact the development of esophagitis in breast cancer patients undergoing supraclavicular radiation. METHODOLOGY:  From January to June 2023, an observational study was conducted at Bangabandhu Sheikh Mujib Medical University in Bangladesh. The patients received radiation therapy (40.05 Gy in 15 parts) to the chest wall and supraclavicular node for three weeks. We were able to guess the following from the dose volume histogram (DVH) data: the length of the esophagus in the treatment area (i.e., the size of the esophagus that was visible on the planning CT scan), the maximum dose (Dmax), the mean dose (Dmean), and the volume of the 10Gy (V10Gy) and 20Gy (V20Gy) doses that were given to the esophagus. During radiotherapy, patients were checked on once a week, and the radiotherapy oncology group was used to evaluate and grade esophagitis Results: Patients with left-sided breast cancer showed a higher Dmean, Dmax, and length of the esophagus compared to those with right-sided breast cancer. Specifically, the Dmean was 6.7 (±2.1) Gy, the Dmax was 39.2 (±1.5) Gy, and the length of the esophagus was 6.1 (±1.2) Gy. Patients with left breast cancer had elevated V10Gy and V20Gy values for the esophagus, but the difference was not statistically significant. The incidence of V10Gy for right-sided breast cancer and left-sided breast cancer was 4.2% (±2.6%) and 19.8% (±9.2%), respectively. The V20Gy was 2.4% (±0.9%) for right-sided breast cancer and 13.09% (±5.0%) for left-sided breast cancer Conclusion: In conclusion, there is a strong association between the mean oesophageal dose and radiation to the left supraclavicular region following surgery in women with breast cancer and acute esophagitis. We can reduce esophageal toxicity by prescribing dose restrictions and performing precise delineation of the esophagus.

Subtractive genomics study for the identification of therapeutic targets against Cronobacter sakazakii: A threat to infants.

Cronobacter sakazakii is an opportunistic pathogen that has been associated with severe infection in neonates such as necrotizing enterocolitis (NEC), neonatal meningitis, and bacteremia. This pathogen can survive in a relatively dry environment, especially in powdered infant formula (PIF). Unfortunately, conventional drugs that were once effective against C. sakazakii are gradually losing their efficacy due to rising antibiotic resistance. In this study, a subtractive genomic approach was followed in order to identify potential therapeutic targets in the pathogen. The whole proteome of the pathogen was filtered through a step-by-step process, which involved removing paralogous proteins, human homologs, sequences that are less essential for survival, proteins with shared metabolic pathways, and proteins that are located in cells other than the cytoplasmic membrane. As a result, nine novel drug targets were identified. Further, the analysis also unveiled that the FDA-approved drug Terbinafine can be repurposed against the Glutathione/l-cysteine transport system ATP-binding/permease protein CydC of C. sakazakii. Moreover, molecular docking and dynamics studies of Terbinafine and CydC suggested that this drug can be used to treat C. sakazakii infection in neonates. However, for clinical purposes further in vitro and in vivo studies are necessary.

Use of relevancy and complementary information for discriminatory gene selection from high-dimensional gene expression data.

With the advent of high-throughput technologies, life sciences are generating a huge amount of varied biomolecular data. Global gene expression profiles provide a snapshot of all the genes that are transcribed in a cell or in a tissue under a particular condition. The high-dimensionality of such gene expression data (i.e., very large number of features/genes analyzed with relatively much less number of samples) makes it difficult to identify the key genes (biomarkers) that are truly attributing to a particular phenotype or condition, (such as cancer), de novo. For identifying the key genes from gene expression data, among the existing literature, mutual information (MI) is one of the most successful criteria. However, the correction of MI for finite sample is not taken into account in this regard. It is also important to incorporate dynamic discretization of genes for more relevant gene selection, although this is not considered in the available methods. Besides, it is usually suggested in current studies to remove redundant genes which is particularly inappropriate for biological data, as a group of genes may connect to each other for downstreaming proteins. Thus, despite being redundant, it is needed to add the genes which provide additional useful information for the disease. Addressing these issues, we proposed Mutual information based Gene Selection method (MGS) for selecting informative genes. Moreover, to rank these selected genes, we extended MGS and propose two ranking methods on the selected genes, such as MGSf-based on frequency and MGSrf-based on Random Forest. The proposed method not only obtained better classification rates on gene expression datasets derived from different gene expression studies compared to recently reported methods but also detected the key genes relevant to pathways with a causal relationship to the disease, which indicate that it will also able to find the responsible genes for an unknown disease data.

Sumithion induced structural erythrocyte alteration and damage to the liver and kidney of Nile tilapia.

Indiscriminate use of pesticides in agricultural land poses a potential threat to many non-target organisms, including fish. In the present study, we explored the toxicological effects of sumithion on Nile tilapia (Oreochromis niloticus) after exposure at different concentrations (0.0, 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0 mg/L) in triplicate for 96 h. The 96-h LC50 value of the pesticide for the test fish was calculated by probit analysis, which was 2.579 mg/L. We also investigated the haematological parameters, erythrocytic alteration and histopathological responses of Nile tilapia. Red blood cell (RBC) and haemoglobin (Hb) level were significantly declined, whereas white blood cell (WBC) and blood glucose level were increased dramatically in the sumithion treated fish. The frequencies of erythrocytic cellular and nuclear alterations were significantly elevated in the fish after exposure to sumithion compared with the control group. The substantial histopathological alterations were observed in sumithion-exposed fish, including pyknotic nucleus, melano-macrophage centers and severe congestion of blood vessels in the liver and patch degeneration, vacuolation and intense form of pyknotic nuclei in the kidney. Observed alterations in this study exhibit that sumithion negatively impacts on Nile tilapia. It is recommended that the use of this pesticide in the agriculture field be monitored and controlled.

Fatal Infection Caused by Chromobacterium violaceum: A Case Report from a Tertiary Care Hospital in Bangladesh.

Chromobacterium violaceum is a Gram-negative bacterium, found in tropical and subtropical regions. C. violaceum infection rarely occurs, but once occurs, it is associated with significant mortality due to severe systemic infection. Since the first human case from Malaysia in 1927, >150 cases of C. violaceum infection have been reported worldwide. We have described here a fatal case of C. violaceum infection in a tertiary care hospital in Dhaka, Bangladesh. To the best of our knowledge, this is the first case of C. violaceum infection in Bangladesh.

Secondary Prevention Medication Use After Myocardial Infarction in U.S. Nursing Home Residents.

BACKGROUND/OBJECTIVES: Secondary prevention medications are recommended for older adults after acute myocardial infarction (AMI), but little is known about whether nursing home (NH) residents receive these medications. The objective was to evaluate new use of secondary prevention medications after AMI in NH residents who were previously nonusers and to evaluate what factors were associated with use. DESIGN: Retrospective cohort using linked national Minimum Data Set assessments; Online Survey, Certification and Reporting records; and Medicare claims. SETTING: U.S. NHs. PARTICIPANTS: National cohort of 11,192 NH residents aged 65 and older who were hospitalized for an AMI between May 2007 and March 2010, had no beta-blocker or statin use for 4 months or longer before the hospitalization, and survived 14 days or more after NH readmission. MEASUREMENTS: The outcome was the number of secondary prevention medications initiated within 30 days of NH readmission. RESULTS: Thirty-seven percent of residents had no secondary prevention medications initiated after AMI, 41% had 1 initiated, and 22% had 2 initiated. After covariate adjustment, fewer secondary prevention medications were used in older residents (proportional odds ratio (POR) = 0.48, 95% confidence interval (CI)  = 0.40-0.57 for ≥95 vs 65-74); women (POR = 0.88, 95% CI = 0.80-0.96);and those with a do-not-resuscitate (DNR) order (POR = 0.90, 95% CI = 0.83-0.98), functional impairment (dependent or totally dependent vs independent to limited assistance, POR = 0.77, 95% CI = 0.69-0.86), and cognitive impairment (moderate to severe vs no impairment, POR = 0.79, 95% CI = 0.70-0.89). CONCLUSION: More than one-third of older NH residents in the United States do not have any secondary prevention medications initiated after AMI, with fewer medications initiated in older residents; women; and those with, DNR orders, poor physical function, and cognitive impairment. A lack of evidence about the safety and effectiveness of secondary preventions medications in the NH population and unmeasured person-centered goals of care are plausible explanations for these findings.
