Purpose This study aims to empirically examine the factors that are likely to affect tourists’ attitudes to revisit, which, in turn, influence their revisit intentions towards beach destinations. Design/methodology/approach Data were collected through a personal-administered survey of 601 tourists from three leading beach destinations in Bangladesh. Findings The empirical results indicate that perceived destination risks affect neither tourists’ attitudes to revisit nor their revisit intentions. However, tourists’ satisfaction and destination image directly affect both their attitudes to revisit and their revisit intentions. Practical implications The findings of this study contribute to the extension of the body of knowledge, especially in beach tourism settings where the proposed relationships have yet to be studied. Originality/value Coastal-based beach tourism is one of the least researched areas in tourism literature. The relationship between tourist attitude to revisit and revisit intention is exclusive in tourism literature.

Data on morphometrics and performance of 106 Black Bengal goats were collected through an in-depth monitoring survey conducted in 73 families of Gangatia, Borachala and Pachpai villages of Bhaluka Upazila, Mymensingh, Bangladesh using a structured questionnaire. Analyses of variance were performed using the General Linear Model (GLM) procedure under Statistical Package for the Social Sciences (SPSS) version 14.0. Differences between mean values were separated using Duncun’s Multiple Range Test (DMRT). Body weight of goats significantly (p<0.001) differed with age classes and  body condition scores. Average body weight of Black Bengal goat was 14.47±0.48 kg. Body length at was 46.01±0.66 cm. Chest girth significantly (p<0.001) differed with age classes and body condition scores. Average chest girth of Black Bengal goat was 56.10±0.60 cm. Wither height significantly (p<0.001) differed with age classes and body size. Average wither height of Black Bengal goat was 46.41±0.36 cm. Scrotal length and scrotal circumference did not significantly (p>0.05) differ with age classes, villages and body condition. The number of services needed for each conception of Solid Black, Toggenburg pattern and Brown Bezoar goats were 1.32±0.31, 1.08±0.22, 1.25±0.31, 1.01±0.26 and 1.23±0.27, respectively. The lowest kidding interval was observed in Borachala village (169.80±38.11 days) and in Solid Black goats (176.71±36.17 days). The highest litter size was found in does (1.68±0.39) of Gangatia village (1.67±0.51) and in Solid Black goats (1.67±0.54). The lowest abortion rate was found in Solid Black goats (6.14%). The lowest kid mortality was observed in Solid Black goats (10.00%).  Variation observed in morphometric and production traits of indigenous Black Bengal goats indicated an opportunity for their improvement through an in-situ pure breeding program.DOI: http://dx.doi.org/10.3329/bjas.v41i2.14122 Bang.

Background. Cytoadherence and sequestration of erythrocytes containing mature stages of Plasmodium falciparum are central to the pathogenesis of severe malaria. The oral anthelminthic drug levamisole inhibits cytoadherence in vitro and reduces sequestration of late-stage parasites in uncomplicated falciparum malaria treated with quinine.Methods. Fifty-six adult patients with severe malaria and high parasitemia admitted to a referral hospital in Bangladesh were randomized to receive a single dose of levamisole hydrochloride (150 mg) or no adjuvant to antimalarial treatment with intravenous artesunate.Results. Circulating late-stage parasites measured as the median area under the parasite clearance curves were 2150 (interquartile range [IQR], 0–28 025) parasites/µL × hour in patients treated with levamisole and 5489 (IQR, 192–25 848) parasites/µL × hour in controls (P = .25). The “sequestration ratios” at 6 and 12 hours for all parasite stages and changes in microvascular blood flow did not differ between treatment groups (all P > .40). The median time to normalization of plasma lactate (<2 mmol/L) was 24 (IQR, 12–30) hours with levamisole vs 28 (IQR, 12–36) hours without levamisole (P = .15).Conclusions. There was no benefit of a single-dose of levamisole hydrochloride as adjuvant to intravenous artesunate in the treatment of adults with severe falciparum malaria. Rapid parasite killing by intravenous artesunate might obscure the effects of levamisole.

Background The situation of coronavirus disease 2019 (COVID-19) pandemic in the Indian subcontinent is worsening. In Bangladesh, rate of new infection has been on the rise despite limited testing facility. Constraint of resources in the health care sector makes the fight against COVID-19 more challenging for a developing country like Bangladesh. Vascular surgeons find themselves in a precarious situation while delivering professional services during this crisis. With the limited number of dedicated vascular surgeons in Bangladesh, it is important to safeguard these professionals without compromising emergency vascular care services in the long term. To this end, we at the National Institute of Cardiovascular Diseases and Hospital, Dhaka, have developed a working guideline for our vascular surgeons to follow during the COVID-19 pandemic. The guideline takes into account high vascular work volume against limited resources in the country. Methods A total of 307 emergency vascular patients were dealt with in the first 4 COVID-19 months (March through June 2020) according to the working guideline, and the results were compared with the 4 pre–COVID-19 months. Vascular trauma, dialysis access complications, and chronic limb-threatening ischemia formed the main bulk of the patient population. Vascular health care workers were regularly screened for COVID-19 infection. Results There was a 38% decrease in the number of patients in the COVID-19 period. Treatment outcome in COVID-19 months were comparable with that in the pre–COVID-19 months except that limb loss in the chronic limb-threatening ischemia patients was higher. COVID-19 infection among the vascular health care professionals was low. Conclusions Vascular surgery practice guidelines customized for the high work volume and limited resources of the National Institute of Cardiovascular Diseases and Hospital, Dhaka were effective in delivering emergency care during COVID-19 pandemic, ensuring safety of the caregivers. Despite the fact that similar guidelines exist in different parts of the world, we believe that the present one is still relevant on the premises of a deepening COVID-19 crisis in a developing country like Bangladesh.
