Levocabastine ameliorates cyclophosphamide-induced cardiotoxicity in Swiss albino mice: Targeting TLR4/NF-κB/NLRP3 signaling pathway.

Cyclophosphamide (CP), although a potent anti-cancer drug, causes cardiotoxicity as a side effect that limits its use. Hence, a specific medicine that can lower cardiotoxicity and be utilised as an adjuvant in cancer treatment is very much needed. In this light, we intended to assess the protective potential of levocabastine (LEV) on CP-induced cardiotoxicity in Swiss albino mice. Mice were administered LEV (50 and 100 µg/kg, i.p.) daily for 14 days and CP at 200 mg/kg, intraperitoneally once on the 7th day. On the 15th day, mice were weighed, blood withdrawn then sacrificed and hearts were removed to estimate various biochemical and histopathological parameters. CP 200 mg/kg significantly increased cardiac troponin T, LDH, CK-MB, interleukin-1ß, IL-6, TNF-α, TBARS, nitrite, and decreased CAT, GSH, and SOD levels, thus, manifested cardiac damage, inflammation, oxidative stress, and nitrative stress, cumulatively causing cardiotoxicity. CP also elevated the expression of various markers including cleaved caspase-3, NF-κB, TLR4, NLRP3, and fibrotic lesions in cardiac tissues, whereas decreased hematological parameters (RBCs, platelets, and Hb) to confirm cardiotoxicity. LEV and fenofibrate (FF) treatment reversed these changes towards normal and showed a significant protective effect against CP. The results showed the protective role of LEV in restoring CP-induced cardiotoxicity in terms of inflammation, apoptosis, oxidative stress, cardiac injury and histopathological damage. Thus, levocabastine can be used as an adjuvant to cyclophosphamide in cancer treatment but a thorough study with various animal cancer models is further needed to establish the fact.

Assessment of South Asian Pediatric Acute Kidney Injury: Epidemiology and Risk Factors (ASPIRE)-a prospective study on "severe dialysis dependent pediatric AKI".

BACKGROUND: Pediatric acute kidney injury (AKI) is a global health concern with an associated mortality risk disproportionately pronounced in resource-limited settings. There is a pertinent need to understand the epidemiology of pediatric AKI in vulnerable populations. Here, we proposed a prospective study to investigate the epidemiology and associated risk factors of "severe dialysis dependent AKI" in children among South Asian nations which would be the first and largest of its kind. METHODS: The ASPIRE study (part of PCRRT-ICONIC Foundation initiative) is a multi-center, prospective observational study conducted in South Asian countries. All children and adolescents ≤ 18 years of age who required dialysis for AKI in any of the collaborating medical centers were enrolled. Data collection was performed until one of the following endpoints was observed: (1) discharge, (2) death, and (3) discharge against medical advice. RESULTS: From 2019 to 2022, a total of 308 children with severe AKI were enrolled. The mean age was 6.17 years (63% males). Secondary AKI was more prevalent than primary AKI (67.2%), which predominantly occurred due to infections, dehydration, and nephrotoxins. Common causes of primary AKI were glomerulonephritis, hemolytic uremic syndrome, lupus nephritis, and obstructive uropathy. Shock, need for ventilation, and coagulopathy were commonly seen in children with severe AKI who needed dialysis. The foremost kidney replacement therapy used was peritoneal dialysis (60.7%). The mortality rate was 32.1%. CONCLUSIONS: Common causes of AKI in children in South Asia are preventable. Mortality is high among these children suffering from "severe dialysis dependent AKI." Targeted interventions to prevent and identify AKI early and initiate supportive care in less-resourced nations are needed.

Returning personal genetic information on susceptibility to arsenic toxicity to research participants in Bangladesh.

BACKGROUND: There is growing consensus that researchers should offer to return genetic results to participants, but returning results in lower-resource countries has received little attention. In this study, we return results on genetic susceptibility to arsenic toxicity to participants in a Bangladeshi cohort exposed to arsenic through naturally-contaminated drinking water. We examine the impact on behavioral changes related to exposure reduction. METHODS: We enrolled participants from the Health Effects of Arsenic Longitudinal Study who had (1) high arsenic (≥150 µg/g creatinine) in a recent urine sample and (2) existing data on genetic variants impacting arsenic metabolism efficiency (AS3MT and FTCD). We used genetic data to recruit three study groups, each with n = 103: (1) efficient metabolizers (low-risk), (2) inefficient metabolizers (high-risk), and (3) a randomly-selected control group (NCT05072132). At baseline, all participants received information on the effects of arsenic and how to reduce exposure by switching to a low arsenic well. The two intervention groups also received their arsenic metabolism efficiency status (based on their genetic results). Changes in behavior and arsenic exposure were assessed using questionnaires and urine arsenic measures after six months. RESULTS: Clear decreases in urine arsenic after six months were observed for all three groups. The inefficient group self-reported higher levels of attempted switching to lower arsenic wells than the other groups; however, there was no detectable difference in urine arsenic reduction among the three groups. Participants showed strong interest in receiving genetic results and found them useful. The inefficient group experienced higher levels of anxiety than the other groups. Among the efficient group, that receiving genetic results did not appear to hinder behavioral change. CONCLUSION: Returning genetic results increased self-reported exposure-reducing behaviors but did not have a detectable impact on reducing urine arsenic over and above a one-on-one educational intervention.

Rates of adverse clinical events in patients with chronic kidney disease: analysis of electronic health records from the UK clinical practice research datalink linked to hospital data.

BACKGROUND: Further understanding of adverse clinical event rates in patients with chronic kidney disease (CKD) is required for improved quality of care. This study described baseline characteristics, adverse clinical event rates, and mortality risk in patients with CKD, accounting for CKD stage and dialysis status. METHODS: This retrospective, noninterventional cohort study included data from adults (aged ≥ 18 years) with two consecutive estimated glomerular filtration rates of < 60 ml/min/1.73 m2, recorded ≥ 3 months apart, from the UK Clinical Practice Research Datalink of electronic health records obtained between January 1, 2004, and December 31, 2017. Select adverse clinical events, associated with CKD and difficult to quantify in randomized trials, were assessed; defined by Read codes and International Classification of Diseases, Tenth Revision codes. Clinical event rates were assessed by dialysis status (dialysis-dependent [DD], incident dialysis-dependent [IDD], or non-dialysis-dependent [NDD]), dialysis modality (hemodialysis [HD] or peritoneal dialysis [PD]), baseline NDD-CKD stage (3a-5), and observation period. RESULTS: Overall, 310,953 patients with CKD were included. Comorbidities were more common in patients receiving dialysis than in NDD-CKD, and increased with advancing CKD stage. Rates of adverse clinical events, particularly hyperkalemia and infection/sepsis, also increased with advancing CKD stage and were higher in patients on HD versus PD. Mortality risk during follow-up (1-5-year range) was lowest in patients with stage 3a NDD-CKD (2.0-18.5%) and highest in patients with IDD-CKD (26.3-58.4%). CONCLUSIONS: These findings highlight the need to monitor patients with CKD for comorbidities and complications, as well as signs or symptoms of clinical adverse events.

Seroprevalence and haemato-biochemical effects of bovine leucosis in buffalo, Punjab, Pakistan.

Enzootic bovine leucosis is caused by bovine leukaemia virus (BLV), a Deltaretrovirus belonging to the family Retroviridae. BLV causes huge economic losses to the dairy industry in the form of decreased milk production, premature culling, and poor reproductive performance of the animals. The aim of the present study was to determine the seroprevalence of BLV infection in buffalo in two districts of Punjab, Pakistan. A total of 384 samples were collected and analysed using a commercial indirect enzyme-linked immunosorbent assay (ELISA) to investigate the seroprevalence of BLV through the detection of the anti-BLV gp51 antibody. A predesigned data questionnaire proforma was employed to find out the association of risk factors with disease. Overall, 18.2% of buffaloes were seropositive for BLV in the study population. The results revealed a significant association (P < 0.05) of age with BLV infection. Furthermore, milk yield and pregnancy had a significant association with the seroprevalence of BLV infection in buffalo whereas no significant association was found with sex, breeding, and health status. Biochemical and oxidative stress markers revealed a significant decrease in liver enzymes alanine transaminase (ALT) and aspartate transaminase (AST), glutathione peroxidase (GPX), and superoxide dismutase (SOD) in seropositive animals as compared to healthy animals. It is concluded that BLV has a considerable prevalence in buffalo in Punjab, Pakistan and there is a dire need to investigate the disease epidemiology at both national and international levels and strategies should be developed to implement an effective control program.

Impact of graded levels of coated calcium butyrate on growth performance and serological indices during pre-weaning stage in Holstein calves.

The study aimed to analyze the impact of calcium butyrate supplementation in calf starter on growth performance indices associated with early rumen development to decrease the volume of milk or milk replacer feeding and enhance early starter intake in Holstein calves. For this purpose, twelve Holstein calves were randomly assigned into three treatments (n = 4/treatment); a control without coated calcium butyrate, T1, and T2 treatments supplemented with coated calcium butyrate 3 g and 6 g per day/head, respectively. Body weight was measured at days 7, 14, 21, 28, 35, 42, 49, and 56 of the trial, and the average daily weight gain and feed conversion ratio were determined. Blood samples were collected at 14, 28, 42, and 56 days of trial for serological parameters. Gut morphometry was performed at the end of trial at slaughtering by collecting duodenal samples. Furthermore, the meat was also evaluated for its quality parameters including pH and tenderness after slaughtering. The results indicated that the feed intake, average daily weight gain, feed conversion ratio, and gut morphometric parameters involving villus height and crypts depth of calves were improved in coated calcium butyrate-supplemented groups. Furthermore, the supplementation of calf starter with coated calcium butyrate significantly enhanced serum concentrations of glucose and total protein. Besides, Beta hydroxy butyrate (BHBA) levels of blood were also found to be elevated in both treatment groups. However, it was revealed that coated calcium butyrate supplementation had no significant effect on meat quality parameters. In conclusion, the supplementation of calf starter with coated calcium butyrate could improve calf performance.

Arsenic exposure from drinking water and endothelial dysfunction in Bangladeshi adolescents.

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide, with ∼80% of CVD-related deaths occurring in low- and middle-income countries. Growing evidence suggests that chronic arsenic exposure may contribute to CVD through its effect on endothelial function in adults. However, few studies have examined the influence of arsenic exposure on cardiovascular health in children and adolescents. To examine arsenic's relation to preclinical markers of endothelial dysfunction, we enrolled 200 adolescent children (ages 15-19 years; median 17) of adult participants in the Health Effects of Arsenic Longitudinal Study (HEALS), in Araihazar, Bangladesh. Participants' arsenic exposure was determined by recall of lifetime well usage for drinking water. As part of HEALS, wells were color-coded to indicate arsenic level (<10 µg/L, 10-50 µg/L, >50 µg/L). Endothelial function was measured by recording fingertip arterial pulsatile volume change and reactive hyperemia index (RHI) score, an independent CVD risk factor, was calculated from these measurements. In linear regression models adjusted for participant's sex, age, education, maternal education, land ownership and body weight, individuals who reported always drinking water from wells with >50 µg/L arsenic had a 11.75% lower level of RHI (95% CI: -21.26, -1.09, p = 0.03), as compared to participants who drank exclusively from wells with ≤50 µg/L arsenic. Sex-stratified analyses suggest that these associations were stronger in female participants. As compared to individuals who drank exclusively from wells with ≤50 µg/L arsenic, the use of wells with >50 µg/L arsenic was associated with 14.36% lower RHI (95% CI: -25.69, -1.29, p = 0.03) in females, as compared to 5.35% lower RHI (95% CI: -22.28, 15.37, p = 0.58) in males for the same comparison. Our results suggest that chronic arsenic exposure may be related to endothelial dysfunction in adolescents, especially among females. Further work is needed to confirm these findings and examine whether these changes may increase risk of later adverse cardiovascular health events.

D-pinitol attenuates isoproterenol-induced myocardial infarction by alleviating cardiac inflammation, oxidative stress and ultrastructural changes in Swiss albino mice.

Cardiovascular diseases are the most disturbing problems throughout the world. The side effects of existing drugs are continuously compelling the scientist to look for better options in terms of safety, efficacy and cost-effectiveness. Our study is also a move in this direction. We have chosen D-pinitol to see its cardioprotective role in isoproterenol-induced myocardial infarction in Swiss albino mice. Grouping was made by dividing mice into eight groups (n = 6). Group I, control; Group II, isoproterenol (ISO) (150 mg/kg, i.p.); Group III, D-pinitol (PIN) (25 mg); Group IV, PIN (50 mg); Group V, PIN (100 mg) per kg per oral, respectively with ISO; Group VI, PIN per se (100 mg D-pinitol only); Group VII, Propranolol (PRO) (20 mg/kg/oral) with ISO; and Group VIII, PRO per se (20 mg/kg, p.o.). After 24 h of the last dose, the blood sample was collected for biochemical parameters, then mice were, killed through cervical dislocation under anaesthesia and cardiac tissue was collected for biochemical, histopathological and ultrastructural evaluation. Administration of ISO in mice altered the level of antioxidant markers, cardiac injury markers and inflammatory markers, which were significantly restored towards normal by D-pinitol at the dose of 50 and 100 mg. 25 mg of D-pinitol dosage, did not produce significant cardio protection. The histopathological and ultrastructural analysis further confirmed these findings. Our study showed that D-pinitol significantly protected myocardial damage which was induced by ISO and reverted oxidative stress and inflammation considerably.

The double burden of maternal overweight and short stature and the likelihood of cesarean deliveries in South Asia: An analysis of national datasets from Bangladesh, India, Maldives, Nepal, and Pakistan.

BACKGROUND: The aim was to investigate: (a) whether there is an association between the maternal double burden of overweight and short stature and the risk of cesarean delivery and (b) whether socioeconomic status (SES) acts as a moderator in the association between the maternal double burden of overweight and short stature and the risk of cesarean birth (CB). MATERIALS AND METHODS: The data for this study were obtained from the nationally representative Demographic and Health Survey databases of five South Asian countries. The analyses were based on responses from married women between 15 and 49 years of age. The risk of CB was the primary outcome, while the maternal double burden of overweight and short stature (coexistence of overweight and short stature) was the exposure of interest. RESULTS: Maternal double burden of overweight and short stature was significantly associated with 179% higher likelihood of undergoing CB in South Asia (SA), with 304%, 200%, 167%, 155%, and 125% higher likelihood of undergoing CB in Nepal, Pakistan, India, Maldives, and Bangladesh, respectively. Findings also demonstrated that mothers belonging to low SES groups with a double overweight and short stature burden were not uniquely disadvantaged. CONCLUSIONS: A significant marker in SA of higher risk of CB is the maternal double burden of overweight and short stature. The negative effect of the maternal double burden of overweight and short stature extends across all economic backgrounds in relation to the risk of CB. It is not limited to poor mothers who suffer from the double burden of overweight and short stature.

Ulva fasciata, a green alga, attenuates the kidney and liver dysfunctions in rats induced by acetaminophen.

Acetaminophen (AAP) is an analgesic-antipyretic drug which is considered safe at recommended dose, but its overuse may induce renal and hepatic injuries. Marine macro algae have great potential against drug-induced renal and hepatic dysfunctions. The present study described the reno-protective and hepato-protective effects of the ethanol extract of an edible green alga Ulva fasciata and its fractions (n-hexane, chloroform and methanol) against AAP toxicity. In the 1st set of experiment, rats were divided into five groups. Of which two were treatment groups beside three controls, the first treatment group was given ethanol extract of U. fasciata alone and the second group was given the same extract with AAP. In the 2nd set of experiment, rats were divided into nine groups, of which three treatment groups administered n-hexane, chloroform and methanol fractions of ethanol extract of U. fasciata respectively while other three treatment groups received the same fractions individually with AAP. On the 11th day, rats were decapitated after 12 h of fasting from both sets, blood samples were collected for assessment of biochemical parameters and kidney tissues were used for determination of oxidants and antioxidants. Histopathological assessment was also done in kidney tissues. A single dose of AAP (600 mg/kg) affected kidney markers including creatinine, urea and blood urea nitrogen (BUN) and hepatic enzymes. Ethanolic extract of U. fasciata normalized kidney and liver markers in AAP intoxicated rats. AAP also reduced glutathione (GSH) in kidney tissues and altered kidney architecture, which were improved by ethanolic extract and chloroform soluble fraction of U. fasciata. A total of 14 polyunsaturated fatty acids were identified from chloroform soluble fraction of U. fasciata by GC-MS and assumed these may be involved in protective activities of U. fasciata.

Ameliorative effect of Spatoglossum asperum and its solvent fractions against acetaminophen-induced liver dysfunction in rats.

Acetaminophen (APAP) is a widely consumed drug for pain management and treatment of pyrexia. However, beyond its recommended dose, it becomes harmful for health and may induce acute liver dysfunction. Current work is designed to ameliorate the APAP induced liver toxicity which was induced in rats by giving intra-peritoneal injection of APAP (800mg/kg) dissolved in 40% polyethylene glycol at day 1 and day 14. APAP dosed/intoxicated rats orally administered either with ethanol extract of Spatoglossum asperum (200mg/kg) and its fractions including n-hexane, chloroform and methanol soluble in a dose of 150mg/kg each daily for 14 days in their respective groups. APAP dosed rats showed remarkable elevation in hepatic biomarkers viz., alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenases, total bilirubin, pro-inflammatory cytokines interleukine-6 and apoptotic protein (caspase-3). In addition, hepatic oxidative stress (lipid per oxidation and indirect nitric oxide) and antioxidant biomarkers (glutathione peroxidase, catalase and reduced glutathione) were also altered. Whereas APAP dosed rats treated with ethanol extract of S. asperum and its fractions showed amelioration in concentration of hepatic enzymes, pro-inflammatory cytokines, apoptotic protein and reduction in hepatic oxidative stress by decreasing the lipid peroxidation, indirect nitric oxide and uplifting the activities of antioxidant enzymes and protein.

Best practices for detection, assessment and management of suspected immune-mediated liver injury caused by immune checkpoint inhibitors during drug development.

Immune checkpoint inhibitors (ICIs) have shown significant efficacy in patients with various malignancies, however, they are associated with a wide range of immune-related toxicities affecting many organs, including the liver. Immune-mediated liver injury caused by checkpoint inhibitors (ILICI) is a distinctive form of drug induced liver injury (DILI), that differs from most DILI types in presumed underlying mechanism, incidence, and response to therapeutic interventions. Despite increased awareness of ILICI and other immune-related adverse effects of ICIs reflected by recent guidelines for their management in post marketing clinical practice, there is lack of uniform best practices to address ILICI risk during drug development. As efforts to develop safer and more effective ICIs for additional indications grow, and as combination therapies including ICIs are increasingly investigated, there is a growing need for consistent practices for ILICI in drug development. This publication summarizes current best practices to optimize the monitoring, diagnosis, assessment, and management of suspected ILICI in clinical trials using ICI as a single agent and in combination with other ICIs or other oncological agents. It is one of several publications developed by the IQ DILI Initiative in collaboration with DILI experts from academia and regulatory agencies. Recommended best practices are outlined pertaining to hepatic inclusion and exclusion criteria, monitoring of liver tests, ILICI detection, approach to a suspected ILICI signal, causality assessment, hepatic discontinuation rules and additional medical treatment.

Edaravone and benidipine protect myocardial damage by regulating mitochondrial stress, apoptosis signalling and cardiac biomarkers against doxorubicin-induced cardiotoxicity.

Background: Doxorubicin (DOX) is a potential chemotherapeutic agent but its use is restricted due to cardiotoxicity. Edaravone is a potent-free radical scavenging agent used in cerebral ischaemia. Benidipine is a triple calcium channel blocker.Objective: We investigated the potential cardioprotective effects of edaravone and benidipine alone and their combination against DOX-induced cardiotoxicity. Cardiotoxicity was induced by administering six equal injections of DOX (2.5 mg/kg) on alternative days for 2 weeks.Result: DOX-treated group showed significant increase level of lipid peroxide and decrease in antioxidant status along with mitochondrial enzymatic activity. Cardiotoxity effect of DOX illustrated by significantly increased the cardiac biomarkers such as Cardiac troponin-I, Brain natriuretic peptide, Creatine kinase-MB in serum. Significant increased activation of TNF-α, Caspase-3 activity and myocardial infarct size in DOX-treated group. Histopathological evaluation also confirmed the DOX-induced cardiotoxicity. Pretreated with edaravone and benidipine was significantly attenuated level of thiobarbituric acid reactive substance, endogenous enzymes, mitochondrial enzyme activities and cardiac biomarkers. Furthermore, pretreated group showed decreased activation of TNF-α, Caspase-3 activity along with reduction in the myocardial infarct size. Histopathological evaluation also strengthened the above results.Conclusion: Taken together these results suggest that the pretreated with edaravone and benidipine have potential protective effect against DOX-induced cardiotoxicity.

Ameliorative effect of nerolidol on cyclophosphamide-induced gonadal toxicity in Swiss Albino mice: Biochemical-, histological- and immunohistochemical-based evidences.

Cyclophosphamide (CP) is commonly used as antineoplastic and immunosuppressant drug with noticeable gonadotoxic profile. Nerolidol (NER) is a sesquiterpene with potent antioxidant and anti-inflammatory properties. Thus, the present study was designed to explore its possible gonadal protective potential against cyclophosphamide-induced testicular, epididymal, seminal and spermatozoal toxicities. Animals were divided into five groups: control (normal saline for 14 days), treatment group (NER 200 and 400 mg/kg, p.o) for 14 days along with a single dose of cyclophosphamide (200 mg/kg, i.p) on 7th day, toxic and Per se groups (cyclophosphamide 200 mg/kg i.p) on 7th day and NER 400 mg/kg for 14 days respectively. Animals were sacrificed on the 15 day, and body weight, weight of reproductive organs, testosterone level, sperm count, biochemical parameters, histopathological and immunohistochemical studies were performed in the testes, epididymis and in the serum. CP administration induced oxidative stress, nitrative stress, inflammation, reduced testosterone level, sperm count, increased expression of MPO and caused histological aberrations in the testes, epididymis and seminal vesicles. CP caused reduced sperm count, sperm motility and testosterone level which got reversed upon treatment with nerolidol in a dose-dependent manner. Nerolidol thus acted as a gonadoprotective molecule and prevented the gonadotoxicity of CP.

Association between temperature, humidity, and COVID-19 outbreaks in Bangladesh.

This study aimed to determine the association between average temperature and humidity with COVID-19 pandemic in Bangladesh. This study included 9,455 confirmed cases during the observation period (March 08, 2020 to May 03, 2020). The peak spread of COVID-19 occurred at an average temperature of 26 °C. We find, under a linear regression framework, high temperature and high humidity significantly reduce the transmission of COVID-19, respectively. It indicates that the arrival of summer and rainy season in Bangladesh can effectively reduce the transmission of the COVID-19. However, it is unlikely that the COVID-19 pandemic diminishes by summer since Bangladesh still have a high coronavirus transmission. Therefore, other public health interventions such as social distancing are still important for blocking the COVID-19 transmission.

Hypolipidemic potential of sterol containing fractions of Jolyna laminarioides: a brown alga.

Solvent fractions (n-hexane, cholorofrom, methanol) and fractions containing sterols of Jolyna laminarioides was evaluated in triton-induced and high-fat-diet induced hyperlipidemic rats. Oral administration of J. laminarioides significantly reduced the elevated level of serum total cholesterol, triglycerides and LDL-c, both in triton induced and high fat diet induced hyperlipidemic rat models with increased serum HDL-c. Chloroform: methanol fraction (2:1) and n-hexane fraction containing sterol showed promising results in reducing LDL-c. The methanol fraction showed hypolipidemic effect by increasing HDL-c (90%). The extracts and fractions of the seaweed also decreased the increased level of cardiac and hepatic marker enzymes beside lowering lipid profile. J. laminarioides exhibited high anti-hyperlipidemic effects both in triton induced and high fat diet induced hyperlipidemic rats.

Hypoglycemic potential of some seaweeds from Karachi coast of Pakistan.

Hypoglycemic activity of ethanol extracts and polysaccharides of seaweeds were studied in Sprague Dawley rats. Based on primary screening of ethanol extracts of 10 seaweeds, three Spatoglossum variabile, Stokeyia indica and Sargassum swartzii were selected for further study and polysaccharides were also extracted from them. Ethanol extracts and polysaccharides were administered to alloxan-induced diabetic rats and glucose level, liver and cardiac enzymes were determined. Antidiabetic activity of ethanol extract of three seaweeds S. swartzii, S. indica and S. variabile caused more than 30% reduction in blood glucose after 6 hours atleast on one dose level (2 mg/200 g and/or 10 mg/200 g body weight) in normal and alloxan diabetic rats. Polysaccharides of these three seaweeds also showed anti-diabetic activity after 6 hours atleast on one dose level (1mg/200 g and/ or 2mg/200g body weight) in normal and alloxan diabetic rats. Seaweed extracts and their polysaccharides caused slight alteration in liver and cardiac enzymes like Serum Glutamate Oxaloacetate Transaminase (SGOT), Serum Glutamate Pyruvate Transaminase (SGPT) and Alkaline Phosphatase (ALP).

Mobile-health tool to improve maternal and neonatal health care in Bangladesh: a cluster randomized controlled trial.

BACKGROUND: In Bangladesh, the targets on reduction of maternal mortality and utilization of related obstetric services provided by skilled health personnel in Millennium Development Goals 5 remains unmet, and the progress in reduction of neonatal mortality lag behind that in the reduction of infant and under-five mortalities, remaining as an essential issue towards the achievement of maternal and neonatal health targets in health related Sustainable Development Goals (SDGs). As access to appropriate perinatal care is crucial to reduce maternal and neonatal deaths, recently several mobile platform-based health programs sponsored by donor countries and Non-Governmental Organizations have targeted to reduce maternal and child mortality. On the other hand, good health-care is necessary for the development. Thus, we designed this implementation research to improve maternal and child health care for targeting SDGs. METHODS/DESIGN: This cluster randomized trial will be conducted in Lohagora of Narail District and Dhamrai of Dhaka District. Participants are pregnant women in the respective areas. The total sample size is 3000 where 500 pregnant women will get Mother and Child Handbook (MCH) and messages using mobile phone on health care during pregnancy and antenatal care about one year in each area. The other 500 in each area will get health education using only MCH book. The rest 1000 participants will be controlled; it means 500 in each area. We randomly assigned the intervention and controlled area based on smallest administrative area (Unions) in Bangladesh. The data collection and health education will be provided through trained research officers starting from February 2017 to August 2018. Each health education session is conducting in their house. The study proposal was reviewed and approved by NCCD, Japan and Bangladesh Medical Research Council (BMRC), Bangladesh. The data will be analyzed using STATA and SPSS software. DISCUSSION: For the improvement of maternal and neonatal care, this community-based intervention using mobile phone and handbook will do great contribution. Thus, a developing country where resources are limited received the highest benefit. Such intervention will guide to design for prevention of other diseases too.

Association between high-risk fertility behaviours and the likelihood of chronic undernutrition and anaemia among married Bangladeshi women of reproductive age.

OBJECTIVE: To explore the association between high-risk fertility behaviours and the likelihood of chronic undernutrition, anaemia and the coexistence of anaemia and undernutrition among women of reproductive age. DESIGN: The 2011 Bangladesh Demographic and Health Survey, conducted from 8 July to 27 December 2011. SETTING: Selected urban and rural areas of Bangladesh. SUBJECTS: A total of 2197 ever-married women living with at least one child younger than 5 years. Exposure was determined from maternal reports of high-risk fertility behaviours. We considered three parameters, maternal age at the time of delivery, birth order and birth interval, to define the high-risk fertility behaviours. Chronic undernutrition, anaemia and the coexistence of anaemia and undernutrition among women were the outcome variables. RESULTS: A substantial percentage of women were exposed to have a high-risk fertility pattern (41·8 %); 33·0 % were at single high-risk and 8·8 % were at multiple high-risk. After adjusting for relevant covariates, high-risk fertility behaviours were associated with increased likelihood of chronic undernutrition (adjusted relative risk; 95 % CI: 1·22; 1·03, 1·44), anaemia (1·12; 1·00, 1·25) and the coexistence of anaemia and undernutrition (1·52; 1·17, 1·98). Furthermore, multiple high-risk fertility behaviours appeared to have more profound consequences on the outcome measured. CONCLUSIONS: Maternal high-risk fertility behaviours are shockingly frequent practices among women in Bangladesh. High-risk fertility behaviours are important predictors of the increased likelihood of women's chronic undernutrition, anaemia and the coexistence of anaemia and undernutrition.

Assessing the link between witnessing inter-parental violence and the perpetration of intimate partner violence in Bangladesh.

BACKGROUND: We aimed to examine the influence of witnessing father-to-mother violence on: 1) perpetration of intimate partner violence (IPV); and 2) endorsement of attitudes justifying wife beating in Bangladesh. METHODS: This paper used data from the 2007 Bangladesh Demographic Health Survey. The analyses were based on the responses of 3374 ever-married men. Exposure to IPV was determined by men's self-reports of witnessing inter-parental violence in childhood. We used adjusted binary logistic regression models to assess the influence of exposure on husbands' perpetration of IPV and their endorsement of attitudes justifying wife beating. RESULTS: Nearly 60% of men reported violent behaviour towards an intimate partner and 35.7% endorsed attitudes justifying spousal abuse. Men who witnessed father-to-mother violence had higher odds of reporting any physical or sexual IPV (adjusted OR [AOR] = 3.26; 95% CI = 2.61, 4.06). Men who had witnessed father-to-mother violence were also 1.34 times (95% CI = 1.08, 1.65) more likely endorse attitudes justifying spousal abuse. CONCLUSIONS: Committing violence against an intimate partner is an all too frequent practice among men in Bangladesh. The study indicated that men who had witnessed father-to-mother violence were more likley to perpetrate IPV, suggesting an intergenerational transmission of violence. This transmission of violence may operate through the learning and modelling of attitudes favourable to spousal abuse. In support of this, witnnessing inter-parental violence was also associated with the endorsement of attitudes justifying spousal abuse. Our findings indicate the continued importance of efforts to identify and assist boys who have witnessed domestic violence and suggest such efforts should aim to change not just behaviours but also attitudes that facilitate such violence.
