Electrophysiological Changes of Sensory Nerves in Patients with Type-2 Diabetes Mellitus of Different Duration
Background: Peripheral neuropathy is a common complication of diabetes mellitus. Among the diabetic neuropathiessymmetrical sensory polyneuropathy is the most common one. Abnormalities of sensory nerve conduction are featuresof diabetic nerve damage. Significant association has been found between electrophysiological parameters of sensorynerves and duration of metabolic derangement in patients with diabetic neuropathy. Objectives: The present study wasdesigned to characterize nerve conduction abnormalities of sensory nerves in subjects with type 2 diabetes mellitus ofdifferent duration and also to assess whether duration of diabetes has any influence on the sensory nerve function.Methods: Forty-four type 2 diabetic subjects were included in two groups:- Group B1 consisted of 23 diabetic subjectshaving duration of diabetes for 5-10 years (shorter duration) and Group B2 consisted of 21 diabetic subjects havingduration of diabetes for 10-15 years (longer duration). Twenty-five age and BMI matched healthy subjects withoutfamily history of diabetes were included as Group A (control) subjects. Sensory nerve conduction velocities, actionpotential amplitudes and latencies of ulnar and sural nerves were measured by a standard NCV-EMG equipment. Result:No significant changes in sensory nerve conduction parameters were observed in the group of diabetic subjects havingshorter duration of diabetes. In the diabetic group with relatively longer duration of diabetes some of the sensory nerveconduction parameters were affected. Among them S SNAP and S NCV were significantly (P<0.01 and <0.05 respectively)reduced in diabetic group with relatively longer duration of diabetes. Conclusion: The results of the study indicated thatneuronal dysfunction for sensory nerves appears after a prolonged exposure to hyperglycemia; there may also be somegenetic and biochemical basis (other than hyperglycemia) for early sensory sparing in type 2 diabetic population ofBangladesh.DOI: 10.3329/bsmmuj.v3i1.5507BSMMU J 2010; 3(1): 9-1
Electrophysiological Changes of Sensory Nerves in Patients with Type-2 Diabetes Mellitus of Different Duration
A comparison of MITS counseling and informed consent processes in Pakistan, India, Bangladesh, Kenya, and Ethiopia
Globally, more than 5 million stillbirths and neonatal deaths occur annually. For many, the cause of death (CoD) is unknown. Minimally invasive tissue sampling (MITS) has been increasingly used in postmortem examinations for ascertaining the CoD in stillbirths and neonates. Our study compared the counseling and consent methods used in MITS projects in five countries in Africa and south Asia. Key informant interviews were conducted with researchers to describe the characteristics and backgrounds of counselors, the environment and timing of consent and perceived facilitators and barriers encountered during the consent process. Counselors at all sites had backgrounds in social science, psychology and counseling or clinical expertise in obstetrics/gynecology or pediatrics. All counsellors received training about techniques for building rapport and offering emotional support to families; training duration and methods differed across sites. Counselling environments varied significantly; some sites allocated a separate room, others counselled families at the bedside or nursing stations. All counsellors had a central role in explaining the MITS procedure to families in their local languages. Most sites did not use visual aids during the process, relying solely on verbal descriptions. In most sites, parents were approached within one hour of death. The time needed for decision making by families varied from a few minutes to 24 h. In most sites, extended family took part in the decision making. Because many parents wanted burial as soon as possible, counsellors ensured that MITS would be conducted promptly after receiving consent. Barriers to consent included decreased comprehension of information due to the emotional and psychological impact of grief. Moreover, having more family members engaged in decision-making increased the complexity of counselling and achieving consensus to consent for the procedure. While each site adapted their approach to fit the context, consistencies and similarities across sites were observed
Healthcare Facilities as Potential Reservoirs of Antimicrobial Resistant Klebsiella pneumoniae:An Emerging Concern to Public Health in Bangladesh
The emergence of virulent extended spectrum β-lactamase producing Klebsiella pneumoniae (ESBL-KP) including carbapenem-resistant Klebsiella pneumoniae (CRKP) in hospital-acquired infections has resulted in significant morbidity and mortality worldwide. We investigated the antibiotic resistance and virulence factors associated with ESBL-KP and CRKP in tertiary care hospitals in Bangladesh and explored their ability to form biofilm. A total of 67 ESBL-KP were isolated from 285 Klebsiella pneumoniae isolates from environmental and patient samples from January 2019 to April 2019. For ESBL-KP isolates, molecular typing was carried out using enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR), antibiotic susceptibility testing, PCR for virulence and drug-resistant genes, and biofilm assays were also performed. All 67 isolates were multidrug-resistant (MDR) to different antibiotics at high levels and 42 isolates were also carbapenem-resistant. The most common β-lactam resistance gene was bla(CTX-M-1) (91%), followed by bla(TEM) (76.1%), bla(SHV) (68.7%), bla(OXA-1) (29.9%), bla(GES) (14.9%), bla(CTX-M-9) (11.9%), and bla(CTX-M-2) (4.5%). The carbapenemase genes bla(KPC) (55.2%), bla(IMP) (28.4%), bla(VIM) (14.9%), bla(NDM-1) (13.4%), and bla(OXA-48) (10.4%) and virulence-associated genes such as fimH (71.6%), ugeF (58.2%), wabG (56.7%), ureA (47.8%) and kfuBC (28.4%) were also detected. About 96.2% of the environmental and 100% of the patient isolates were able to form biofilms. ERIC-PCR-based genotyping and hierarchical clustering of K. pneumoniae isolates revealed an association between environmental and patient samples, indicating clonal association with possible transmission of antimicrobial resistance genes. Our findings can help in improving patient care and infection control, and the development of public health policies related to hospital-acquired infections
COVID-19 among staff and their family members of a healthcare research institution in Bangladesh between March 2020 and April 2021 : a test-negative case–control study
Objective To identify factors associated with COVID- 19 positivity among staff and their family members of icddr,b, a health research institute located in Bangladesh. Setting Dhaka, Bangladesh. Participants A total of 4295 symptomatic people were tested for SARS-CoV-2 by reverse-transcription PCR between 19 March 2020 and 15 April 2021. Multivariable logistic regression was done to identify the factors associated with COVID- 19 positivity by contrasting test positives with test negatives. Result Forty-three per cent of the participants were tested positive for SARS-CoV-2. The median age was high in positive cases (37 years vs 34 years). Among the positive cases, 97% were recovered, 2.1% had reinfections, 24 died and 41 were active cases as of 15 April 2021. Multivariable regression analysis showed that age more than 60 years (adjusted OR (aOR)=2.1, 95% CI 1.3 to 3.3; pwere tested negative. Conclusions The study findings suggest that older age, fever, cough and anosmia were associated with COVID- 19 among the study participants.publishedVersionPeer reviewe

Biomarkers of Prostatic Cancer: An Attempt to Categorize Patients into Prostatic Carcinoma, Benign Prostatic Hyperplasia, or Prostatitis Based on Serum Prostate Specific Antigen, Prostatic Acid Phosphatase, Calcium, and Phosphorus
Prostatitis, BPH, and P.Ca are the most frequent pathologies of the prostate gland that are responsible for morbidity in men. Raised levels of PSA are seen in different pathological conditions involving the prostate. PAP levels are altered in inflammatory or infectious or abnormal growth of the prostate tissue. Serum calcium and phosphorus levels were also found to be altered in prostate cancer and BPH. The present study was carried out to study the levels of PSA, PAP, calcium, and phosphorus in serum of patients with Prostatitis, BPH, or P.Ca and also to evaluate the relationship between them. Males in the age group of 50–85 years with LUTS disease symptoms and with PSA levels more than 4 ng/mL were included. A total of 114 patients were analyzed including 30 controls. Prostatitis in 35.7% of cases, BPH in 35.7% of the cases, and P.Ca in 28.57% of the cases were observed. Thus, the nonmalignant cases constitute a majority. PSA, a marker specific for prostatic conditions, was significantly high in all the diseases compared to controls. A rise in serum PSA and PAP indicates prostatitis or, in combination with these two tests, decreased serum calcium shows advanced disease
Antibiotic Usage and Resistance in Food Animal Production: What Have We Learned from Bangladesh?
Irrational and inappropriate use of antibiotics in commercial chicken and aquaculture industries can accelerate the antibiotic resistance process in humans and animals. In Bangladesh, the growing commercial chicken and aquaculture industries are playing significantly important roles in the food value chain. It is necessary to know the antibiotic usage practices and antibiotic resistance in food animal production to design rational policies, guidelines, and interventions. We conducted a narrative review to understand the level of antibiotic usage and resistance in food animal production in Bangladesh. Information about antibiotic usage in different food animal production systems, including commercial chickens and aquaculture in Bangladesh is inadequate. Only a few small-scale studies reported that the majority (up to 100%) of the broiler and layer chicken farms used antibiotics for treating and preventing diseases. However, numerous studies reported antibiotic-resistant bacteria of public health importance in commercial chicken, fish, livestock, and animal origin food. The isolates from different pathogenic bacteria were found resistant against multiple antibiotics, including quinolones, the third or fourth generation of cephalosporins, and polymyxins. Veterinary practitioners empirically treat animals with antibiotics based on presumptive diagnosis due to inadequate microbial diagnostic facilities in Bangladesh. Intensive training is helpful to raise awareness among farmers, feed dealers, and drug sellers on good farming practices, standard biosecurity practices, personal hygiene, and the prudent use of antibiotics. Urgently, the Government of Bangladesh should develop and implement necessary guidelines to mitigate irrational use of antibiotics in food animals using a multi-sectoral One Health approach
Why Bangladeshi nurses avoid 'nursing': Social and structural factors on hospital wards in Bangladesh
In response to concerns that nurses spend less than 6% of their time on direct patient care, this study explored factors that influence nurses' behaviour in the provision of 'hands on' care in hospitals in Bangladesh. Through in-depth interviews with female nurses and patients and their co-workers in six hospitals, we identified conflicts between the inherited British model of nursing and Bangladeshi societal norms. This was most evident in the areas of night duty, contact with strangers, and involvement in 'dirty' work. The public was said to associate nursing activities with commercial sex work. As a consequence, their value on the 'bride market' decreases. To minimise the stigma associated with their profession, nurses in government hospitals distance themselves from patients, using nurse surrogates in the form of patients' relatives and hospital support workers to carry out their work. These adaptations are supported and sustained through unofficial activities developed over time within hospitals. In contrast nurses in NGO hospitals give more direct patient care themselves and do not rely on carers as much because of tight supervision and limited visitor hours. Initiatives undertaken to improve the quality of patient care, such as enlarging the nursing workforce or providing clinical instruction, which do not take into account the prevailing culture in hospitals and social conflicts faced by nurses, are unlikely to succeed. Fundamental decisions on how to care for the sick in Bangladesh are required. If the present nursing curriculum is followed, adequate supplies, supervision and accountability are prerequisites for its implementation.Bangladesh Social conflict Cultural values Nurse-patient relationship Qualitative research
