ABSTRACT

Acute myocardial infarction (AMI) patients characterize a large proportion of admissions in coronary care unit and their management and risk stratification is of immense importance. Hypomagnesemia is a long-term risk factor for incident of both myocardial infarction and arrhythmia. We assessed whether serum magnesium levels at admission is associated with arrhythmias and in-hospital mortality in patients with acute myocardial infarction (AMI). The aim of the study was to evaluate the prognostic implications of serum magnesium level in patients with acute myocardial infarction. This cross-sectional observational study was conducted in the department of cardiology in Mymensingh Medical College Hospital from October 2017 to March 2019. Total 259 acute myocardial infarction patients were included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group-I: Patients with acute myocardial infarction with serum magnesium ≥1.82mg/dl. Group-II: Patients with acute myocardial infarction with serum magnesium <1.82mg/dl. Serum magnesium level was measured on admission, and the incidence of in-hospital major cardiac events was assessed. In this study mean serum magnesium level of Group-I, Group-II were 2.21±0.14mg/dl, 1.60±0.15mg/dl respectively. It was statistically significant (p<0.05). In-hospital outcomes of the study group revealed that low risk group patients were uneventful outcome during hospitalization period, they had no any complication. In Group-I patient, 9(4.8%) were developed arrhythmias, 26(13.9%) were developed heart failure, 9(4.8%) were developed cardiogenic shock and 3(1.6%) were died and in Group-II patient, 44(61.10%) developed arrhythmias, 9(12.50%) were developed heart failure, 7(9.7%) were developed cardiogenic shock and 12(16.7%) were died out of them which was statistically significant (p<0.05). Mean duration of hospital stay of the study population according serum magnesium level was in Group-I, 4.27±0.68 days, in Group-II, 5.84±1.05 days which was statistically significant (p<0.05). In conclusion patient with serum magnesium level less than 1.82mg/dl increased the risk of in-hospital arrhythmia and death.

ABSTRACT

Sedentary lifestyle are spreading worldwide because of lack of available spaces for exercise, increased occupational sedentary behaviors such as office work and the increased prevalence of television and video devices. Increased incidence of sedentary lifestyle and obesity in developed and developing countries is one of the major risk factors for the development of cardiovascular diseases. This study was undertaken to analyze the differences in anthropometric and cardiovascular parameters in sedentary and non-sedentary male subjects. This analytical type of cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2021 to June 2022. This study consisted 50 male employees of 25-60 years who worked in an office were study group (Group II) and control group Group-I) consisted of 50 male age matched physical laborers. BMI was calculated as weight in kilogram divided by the height in meter square i.e. kg/m². Blood Pressure was measured by indirect auscultatory method with an aneroid sphygmomanometer. Statistical analysis was done by using Student’s un-paired ‘t’ test. Values expressed as mean ± standard deviation. P value was taken as significant at 5 percent confidence level. The mean±SD BMI in kg/m² of Group I and Group II were 21.90±2.22 and 29.32±3.13 respectively. The mean±SD systolic blood pressure of Group I and Group II were 112.20±6.79 and 145.10±8.11 and mean±SD diastolic blood pressure of Group I and Group II were 72.80±5.73 and 91.00±5.05 respectively. The BMI and blood pressure were increased in sedentary group compared to non-sedentary group. From the study, it appears that the risk for cardiovascular disease is increased in sedentary workers.

ABSTRACT

The prevalence of diabetes mellitus is a significant global public health concern, particularly in emerging nations like Bangladesh. Bangladesh is already overrun with non-communicable diseases while still battling communicable diseases. About 90.0% of all cases of diabetes that have been diagnosed are type 2 diabetes. High calorie diet, age, sedentary lifestyle and obesity are the main risk factors for type 2 diabetes. Different micronutrients have been linked to an increased incidence of diabetes in addition to existing risk factors. The goal of the study was to assess the serum levels of calcium and magnesium in people with type 2 diabetes mellitus and compare them to those in healthy controls. This cross-sectional study was conducted from July 2018 to June 2019 at the Mymensingh Medical College, Mymensingh, Department of Biochemistry in cooperation with the Department of Endocrinology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Purposive (non-random) sampling was used to pick the subjects based on inclusion and exclusion criteria. This study had 100 individuals in total. Out of them, 50 people with type 2 diabetes mellitus who had been diagnosed were chosen as cases, and another 50 people who appeared to be in generally good health were chosen as controls. Serum calcium and magnesium levels were measured for this study’s analytical purposes. The mean±SD was used to express all values. The statistical package for social science (SPSS), a Windows application, was used to conduct the statistical analyses. Using the Student’s unpaired ‘t’ test, the statistical significance of the difference between the case and control groups was assessed. Following comprehensive analysis, it was discovered that type 2 diabetes mellitus patients had considerably lower mean serum calcium (in case group was 8.46±0.63 and control group 8.86±0.64mg/dl) and magnesium levels (in case group was 2.09±0.42 and control group 2.24±0.16mg/dl) than healthy controls. According to the results of the current investigation, patients with type 2 diabetes mellitus had significantly altered serum calcium and magnesium levels. As a result, the study’s hypothesis was accepted.

ABSTRACT

Hypertension or elevated blood pressure is a serious medical condition that significantly increases the risks of heart, brain, kidney and other diseases. An estimated 1.28 billion adults aged 30-79 years worldwide have hypertension, most (two-thirds) living in low- and middle-income countries. An estimated 46.0% of adults with hypertension are unaware that they have the condition. In Bangladesh, 21.3 million of the adult population has hypertension and that is 21.0% of total population. About half of them (48.7%) with hypertension are diagnosed and 34.9% are under treatment. One of the global targets for non communicable diseases is to reduce the prevalence of hypertension by 33.0% between 2010 and 2030. This study was done to evaluate the effects of hypertension and to find out the major complications occurring due to hypertension. This analytical type of cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from January 2021 to December 2021. A total number of 120 male subjects, age ranged from 20-59 years was included in this study. Among them, sixty (60) hypertensive subjects were taken as study group (Group II) and sixty (60) ages matched normotensive adult male subjects were taken as control group (Group I). The results were calculated and analyzed by using Statistical package for social science (SPSS). Anthropometric measurements such as height and weight were taken in meter and kilogram respectively. Systolic and diastolic blood pressure were measured by Aneroid Sphygmomanometer (ALPK2, Japan), laboratory analysis of fasting serum total cholesterol by CHOD-POD method, fasting serum triglycerides by GPO-POD method. In this study we found that in study group Mean±SD of body mass index (29.36±2.60, p<0.001), fasting serum total cholesterol (232.05±11.18, p<0.001) and fasting serum triglycerides (180.67±19.44, p<0.001) which were significantly increased with comparison to control group. It’s concluded from this study we recommended that routine estimation of these parameters is important for prevention of complication related to hypertension for leading a healthy life.

ABSTRACT

The oral contraceptive pill, ‘the pill’, was introduced in the starting of the 1960s. Presently, worldwide about 100 million women are current users of combined hormonal contraceptives (COC) most frequently used in the western world. The most frequently used agents are a combination of drugs containing both the estrogen and progesterone. This combination is considered to be highly efficacious, generally considered 99.9% and a use effectiveness of 97.0% to 98.0%. This study was done to evaluate the changes of Body Mass Index (BMI) and Blood pressure ( BP) in combined oral contraceptive pill users in comparison to non- users. This cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2021 to June 2022. Total number of 120 reproductive aged women, age ranged from 15-55 years was included in this study. Among them, sixty (60) combined oral contraceptive pill users subjects were taken as study group (Group II) and sixty (60) age matched oral pill non users subjects were taken as control group (Group I). Data were expressed as mean±SD and statistical significance of difference among the group was calculated by unpaired students’ ‘t’ test and Pearson’s correlation coefficient test. The mean±SD of BMI of control group (Group I) and study group (Group II) were 22.50±1.50 kg/m² and 27.64±1.28 kg/m² respectively. In study group (Group II) BMI was increased. Result is statistically highly significant (p<0.001). The mean±SD of systolic blood pressure of control group (Group I) and study group (Group II) were 111.17±8.51 mm of Hg and 127.50±6.14 mm of Hg respectively. In this study the mean±SD of diastolic blood pressure of control group (Group I and study group (Group II) were 75.58±5.05mm of Hg and 87.00±4.89 mm of Hg respectively. In study group (Group II) diastolic blood pressure was increased. Result is statistically highly significant (p<0.001). So the assessment of this parameter is important for early detection and prevention of complication related to combined oral contraceptive pill use for leading a healthy life.

ABSTRACT

Polycystic ovary syndrome (PCOS) is a polygenic and multifactorial condition, regarded as the most common endocrine abnormality of women in reproductive period. It is commonly assumed that insulin resistance, hyperandrogenism and obesity significantly influence the pathophysiological process of PCOS. This study was designed to estimate hormonal parameters in different phenotypes of PCOS. The cross sectional descriptive type of observational study was carried out at Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2018 to June 2019. Data were collected from purposively selected 107 patients with PCOS by interview, clinical examination and laboratory investigations using a pretested case record form. Data were analyzed by computer software, SPSS-version 22.0. Hormonal parameters in different phenotypes of PCOS were compared with ANOVA test. Phenotype A was found in highest number (59.8%) followed by phenotype B (14.9%), phenotype D (14.0%) and phenotype C (11.2%). Biochemical hyperandrogenism was observed highest in phenotype A (57.8%) followed by phenotype B (36.4%) and phenotype C (6.1%). Biochemical or clinical hyperandrogenism was not observed among patients of phenotype D. Altered LH:FSH ratio was high in phenotype A (14.1%) and Phenotype B (2.8%). Increased serum prolactin level was found highest in phenotype A (10.3%) and increased serum TSH was found highest in phenotype D (4.7%). Statistically significant difference was observed among levels of serum testosterone of different phenotypes (p<0.001). Hormonal derangements among different phenotypes reflect the severity of reproductive dysfunction and metabolic aberrations. Screening for metabolic risks of diverse phenotypes is important to detect and prevent long term health consequences of PCOS.

ABSTRACT

BACKGROUND AND OBJECTIVES: High-risk infant follow-up programs (HRIFs) are a recommended standard of care for all extremely low birth weight (ELBW) infants to help mitigate known risks to long-term health and development. However, participation is variable, with known racial and ethnic inequities, though hospital-level drivers of inequity remain unknown. We conducted a study using a large, multicenter cohort of ELBW infants to explore within- and between-hospital inequities in HRIF participation.

METHODS: Vermont Oxford Network collected data on 19 503 ELBW infants born between 2006 and 2017 at 58 US hospitals participating in the ELBW Follow-up Project. Primary outcome was evaluation in HRIF at 18 to 24 months’ corrected age. The primary predictor was infant race and ethnicity, defined as maternal race (non-Hispanic white, non-Hispanic Black, Hispanic, Asian American, Native American, other). We used generalized linear mixed models to test within- and between-hospital variation and inequities in HRIF participation.

RESULTS: Among the 19 503 infants, 44.7% (interquartile range 31.1-63.3) were seen in HRIF. Twenty six percent of the total variation in HRIF participation rates was due to between-hospital variation. In adjusted models, Black infants had significantly lower odds of HRIF participation compared with white infants (adjusted odds ratio, 0.73; 95% confidence interval, 0.64-0.83). The within-hospital effect of race varied significantly between hospitals.

CONCLUSIONS: There are significant racial inequities in HRIF participation, with notable variation within and between hospitals. Further study is needed to identify potential hospital-level targets for interventions to reduce this inequity.

ABSTRACT

Objective: This study aims to evaluate the potential impact of addressing goals-of-care (GOC) with selected patients in the emergency department (ED), GOC documentation, hospital utilization, and patient satisfaction. Method: This is a single-center, retrospective, and prospective, observational convenience-sample study. ED registered nurses (ED RNs) received standardized GOC conversation training. Their selection criteria included a selection interview, a minimum of 3 years of ED clinical experience, and current employment in the ED. ED RNs used a standardized GOC questionnaire. Patient inclusion criteria included age ≥18 years and one or more of the following: chronic kidney disease ≥ stage III, congestive heart failure with an ejection fraction ≤ 40%, chronic obstructive pulmonary disease with home oxygen use, and/or malignancy with metastasis. GOC conversations were recorded in the electronic medical record (EMR). Physician Orders for Life-Sustaining Treatment (POLST) forms were completed as appropriate. Select individual patient data for the 12 months prior to the conversation were compared with the following 12 months. Results: Over 6 months, 94 of 133 patients who were approached consented to the GOC discussion with the RN. All 94 enrolled patients had their GOC recorded into the EMR. One-third already had a completed POLST form prior to ED arrival. 50% without a POLST on ED arrival left with a completed POLST. Eighty-four patients survived the index visit and 46 patients survived to study completion. Patient satisfaction with the interaction was high: In the cohort who survived past the index visit, 95% rated their experience at 4/5 or 5/5 (Likert scale, 5: strongly agree, 1: strongly disagree). In the survival-to-study completion cohort, 100% rated their experience as 4/5 or 5/5. Subsequent median ED visits decreased by 15% (1.0-4.0 interquartile range). There were no statistically significant changes in hospitalizations (both decreased by 25%, 0-3.0) or intensive care unit admissions (0%, 0-0). Conclusions: An ED RN-led GOC conversation had high patient satisfaction and 100% GOC documentation in the EMR. There was a significant increase in ED POLST form completion. There were no significant changes noted in subsequent hospitalizations, length of hospitalization, or intensive care unit utilization.

ABSTRACT

BACKGROUND: Members of racial and ethnic minority groups have been disproportionately impacted by coronavirus-2019 (COVID-19). The objective of the study is to describe associations between race and ethnicity on clinical outcomes such as need for mechanical ventilation and mortality.

METHODS: Retrospective cohort study of patients with severe COVID-19 infection admitted within a large, not-for-profit healthcare system in the mid-Atlantic region between March and July, 2020. Patient demographic data and clinical outcomes were abstracted from the electronic health record. Logistic regressions were performed to estimate associations between race and ethnicity and the clinical outcomes.

RESULTS: The study population (N = 2931) was stratified into 1 of 3 subgroups: non-Hispanic White (n = 466), non-Hispanic Black (n = 1611), and Hispanic (n = 654). The average age of White, Black, and Hispanic patients was 69 ± 17.06, 64 ± 15.9, and 50 ± 15.53 years old, respectively (P < .001). Compared to White patients, Black and Hispanic patients were at increased odds of needing mechanical ventilation due to COVID-19 pneumonia (odds ratio [OR] Black = 1.35, 95% confidence interval [CI] = 1.04 to 1.75, P < .05; OR Hispanic = 1.43, 95% CI = 1.06 to 1.93, P < .05). When compared to White patients, Hispanic patients were at decreased odds of death (OR = 0.45, 95% CI = 0.32 to 0.63, P < .001). However, when adjusting for age, there were no statistically significant differences in the odds of death between these groups (adjusted OR [aOR] Black = 1.05, 95% CI = 0.80 to 1.38, P = .71; aOR Hispanic = 1.10, 95% CI = 0.76 to 1.60, P = .62).

CONCLUSION: Our analysis demonstrated that Hispanic patients were more likely require mechanical ventilation but had lower mortality when compared to White patients, with lower average age likely mediating this association. These findings emphasize the importance of outreach efforts to communities of color to increase prevention measures and vaccination uptake to reduce infection with COVID-19.
