Study of Serum Electrolytes (Sodium and Potassium) Abnormalities in Acute Stroke.

Stroke is the common cause of death and disability worldwide, as well as in Bangladesh. Serum electrolytes abnormalities or dyselectrolytaemia is one of the major acute complications of stroke. Dyselectrolytaemia or serum electrolytes (sodium and potassium) abnormalities are more common in patients with acute stroke that can be easily measured. The study was planned to find out the serum electrolytes (sodium and potassium) abnormalities in acute stroke patients. This cross-sectional study was conducted in the Department of Neurology and Medicine, Mymensingh Medical College and Hospital from January 2019 to June 2020. Total 84 purposively selected patients with acute strokes were evaluated following informed written consent. Diagnosis was confirmed by neuroimaging of brain. Moreover, serum electrolytes level was measured for each patient. Data were collected by interviews, clinical examinations & laboratory investigations of the patients using a case record form and analysis was carried out by the help of SPSS 25.0. Mean age of the patients with acute strokes were 57.65±15.79 years. About two thirds (60.7%) of the patients were male and the remaining (39.3%) were female. Sodium imbalances were observed in 32.2% and potassium imbalances in 25.0% cases. About 66.7% haemorrhagic strokes patients and 42.2% ischaemic strokes patients had dyselectrolytaemia (p<0.05). More than twenty eight percent (28.6%) of all stroke patients had hyponatraemia, which was more common (35.9%) among haemorrhagic strokes patients (p<0.05). Of all stroke patients 21.4% had hypokalaemia, which was more common (28.2%) in haemorrhagic strokes patients (p<0.05). This study reveals that, serum electrolytes (sodium and potassium) abnormalities are more common in haemorrhagic than ischaemic strokes, which is mainly hyponatraemia and hypokalaemia.

The Mortality After Release from Incarceration Consortium (MARIC): Protocol for a multi-national, individual participant data meta-analysis.

INTRODUCTION: More than 30 million adults are released from incarceration globally each year. Many experience complex physical and mental health problems, and are at markedly increased risk of preventable mortality. Despite this, evidence regarding the global epidemiology of mortality following release from incarceration is insufficient to inform the development of targeted, evidence-based responses. Many previous studies have suffered from inadequate power and poor precision, and even large studies have limited capacity to disaggregate data by specific causes of death, sub-populations or time since release to answer questions of clinical and public health relevance. OBJECTIVES: To comprehensively document the incidence, timing, causes and risk factors for mortality in adults released from prison. METHODS: We created the Mortality After Release from Incarceration Consortium (MARIC), a multi-disciplinary collaboration representing 29 cohorts of adults who have experienced incarceration from 11 countries. Findings across cohorts will be analysed using a two-step, individual participant data meta-analysis methodology. RESULTS: The combined sample includes 1,337,993 individuals (89% male), with 75,795 deaths recorded over 9,191,393 person-years of follow-up. CONCLUSIONS: The consortium represents an important advancement in the field, bringing international attention to this problem. It will provide internationally relevant evidence to guide policymakers and clinicians in reducing preventable deaths in this marginalized population. KEY WORDS: Mortality; incarceration; prison; release; individual participant data meta-analysis; consortium; cohort.

Performance of Haematological Parameters in Early Diagnosis of Clinically Suspected Neonatal Sepsis.

Neonatal sepsis is one of the major health problems throughout the world and major cause of morbidity and mortality in developing countries. Positive blood culture considers the gold standard for confirmation of neonatal sepsis, but it does not provide rapid diagnosis. So this study was designed to find out the performance of haematological parameters in early diagnosis of neonatal sepsis. The objective of the study was to evaluate the performance of haematological parameters individually and in combination in early diagnosis of neonatal sepsis. It was a cross-sectional study conducted at neonatal ward, SCANU and obstetric ward of Rangpur Medical College Hospital from January 2014 to December 2015. A total of 70 neonates clinically suspected to have features of sepsis were included in this study. Another 70 healthy term neonates were included in the study as reference group. Blood sample were obtained to estimate TLC, ANC, immature neutrophil count, degenerative changes in PMNs, platelet count, I/T and I/M ratio. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the individual test and tests combination were calculated. Among the haematological parameters, performance of combined tests had high sensitivity, specificity, with PPV and NPV. Among the individual tests I/T and I/M ratio had high sensitivity (95%), specificity (85%, 90%), PPV (90%, 75%) and NPV (90%). There were 22 out of 70 neonates (31.42%) who had culture proven sepsis. Among 22 culture proven sepsis most commonly found organism were Escherichia Coli 12(54.5%) followed by Klebsiella 3(13.63%), Proteus 3(13.63%), Staphylococcus aureus 2(9.9%) and Salmonella 2(9.9%). There is no ideal test for diagnosis of early diagnosis of neonatal sepsis haematological parameters is useful adjunct test in identifying clinically suspected neonatal sepsis.

Dipstick Method versus Spot Urinary Protein Creatinine Ratio for Evaluation of Massive Proteinuria in Childhood Nephrotic Syndrome.

Measurement of massive proteinuria is vital for diagnosis of childhood Nephrotic syndrome. Quantification of 24 hours urinary protein is the gold standard test. Dipstick method of urinary protein measurement gives instant result for massive proteinuria. Spot urinary protein creatinine ratio measurement is variable. This was a hospital based prospective cross sectional study done at Department of Paediatric Nephrology, Rangpur Medical College Hospital from January 2014 to December 2015 to evaluate accuracy of dipstick method versus spot urinary protein-creatinine ratio in estimation of massive proteinuria in childhood nephrotic syndrome. Total 100 children diagnosed as Nephrotic syndrome fulfilling the inclusion and exclusion criteria were enrolled into the study. After collection of spot urine sample, proteinuria was estimated by dipstick method and same sample was sent to laboratory for measuring protein creatinine ratio. All data were collected in individual predetermined case record form and analyzed by SPSS version 17.Dipstick had sensitivity 97%, specificity 70%, positive predictive value 96.7%, negative predictive value 77% and efficacy 95%. There was a significant correlation between spot urinary protein creatinine ratio and dipstick testing of Nephrotic range of proteinuria (p<0.05).The dipstick result of proteinuria significantly correlates with spot urinary protein creatinine ratio. Dipstick method of urinary protein measurement yields accurate result instantly.

Adherence to antipsychotic medication among homeless adults in Vancouver, Canada: a 15-year retrospective cohort study.

PURPOSE: The purpose of this study was to investigate the level of adherence to antipsychotic prescription medication in a well-defined homeless cohort over a 15-year period. We hypothesized that adherence would be well below the recommended threshold for clinical effectiveness (80 %), and that it would be strongly associated with modifiable risk factors in the social environment in which homeless people live. METHOD: Linked baseline data (including comprehensive population-level administrative prescription records) were examined in a subpopulation of participants from two pragmatic-randomized trials that investigated Housing First for homeless and mentally ill adults. Adherence to antipsychotic medication was operationalized using the medication possession ratio. Multivariable logistic regression was used to estimate effect sizes between socio-demographic, homelessness-related and illness factors, and medication possession ratio. RESULTS: Among the 290 participants who met inclusion criteria for the current analysis, adherence to antipsychotic prescription was significantly associated with: history of psychiatric hospitalization; receipt of primary medical services; long-acting injectable antipsychotic formulations; and duration of homelessness. Mean medication possession ratio in the pre-randomization period was 0.41. Socio-demographic characteristics previously correlated with antipsychotic non-adherence were not significantly related to medication possession ratio. CONCLUSIONS: This is the first study to quantify the very low level of adherence to antipsychotic medication among homeless people over an extended observation period of 15 years. Each of the four factors found to be significantly associated with adherence presents opportunities for intervention. Strategies to end homelessness for this population may represent the greatest opportunity to improve adherence to antipsychotic medication.

The prevalence and geographic distribution of complex co-occurring disorders: a population study.

AIMS: A subset of people with co-occurring substance use and mental disorders require coordinated support from health, social welfare and justice agencies to achieve diversion from homelessness, criminal recidivism and further health and social harms. Integrated models of care are typically concentrated in large urban centres. The present study aimed to empirically measure the prevalence and distribution of complex co-occurring disorders (CCD) in a large geographic region that includes urban as well as rural and remote settings. METHODS: Linked data were examined in a population of roughly 3.7 million adults. Inclusion criteria for the CCD subpopulation were: physician diagnosed substance use and mental disorders; psychiatric hospitalisation; shelter assistance; and criminal convictions. Prevalence per 100 000 was calculated in 91 small areas representing urban, rural and remote settings. RESULTS: 2202 individuals met our inclusion criteria for CCD. Participants had high rates of hospitalisation (8.2 admissions), criminal convictions (8.6 sentences) and social assistance payments (over $36 000 CDN) in the past 5 years. There was wide variability in the geographic distribution of people with CCD, with high prevalence rates in rural and remote settings. CONCLUSIONS: People with CCD are not restricted to areas with large populations or to urban settings. The highest per capita rates of CCD were observed in relatively remote locations, where mental health and substance use services are typically in limited supply. Empirically supported interventions must be adapted to meet the needs of people living outside of urban settings with high rates of CCD.

The Cedar project: prevalence and correlates of HIV infection among young Aboriginal people who use drugs in two Canadian cities.

INTRODUCTION: During the past decade, the number of Aboriginal people diagnosed with HIV in Canada has grown more than any other ethnicity. Whereas the majority of infections are related to injection drug use, factors that explain elevated risk and transmission of HIV among Aboriginal young people who use illicit drugs are not well understood. STUDY DESIGN: Observational study. METHODS: The Cedar Project is an observational study of Aboriginal youth living in Vancouver and Prince George, BC. Eligibility criteria include age (14-30 years) and self-reported use of non-injection or injection drugs at least once in the month before enrolment. Between October 2003 and April 2005, 512 participants were recruited and completed a questionnaire administered by an Aboriginal interviewer. Multivariable logistic regression analysis was used to model the independent association of demographic and behavioural variables of individuals with HIV infection. RESULTS: Of the participants, 235 resided in Prince George and 277 in Vancouver. Among the 276 participants that used injection drugs, HIV prevalence was significantly higher in Vancouver (17% vs. 7%) but HCV prevalence was higher in Prince George (62% vs. 57%). In Vancouver, 40% of injectors reported daily heroine use compared with 12% in Prince George. In contrast, Prince George participants were more likely to report daily injection of cocaine compared with those in Vancouver (37% vs. 21%). A higher percentage of Prince George participants reported having difficulty accessing clean syringes (22% vs. 8%). History of non-consensual sex, residing in Vancouver and duration of injection drug use were independent factors associated with increased risk of HIV infection. CONCLUSIONS: HIV and HCV prevalence are elevated in young Aboriginal drug users residing in Vancouver and Prince George. Heterogeneity exists in these locations with respect to drug of choice and access to clean syringes. Prevention and treatment programs are urgently required in this population.

Impact of country of origin on drug-resistant tuberculosis among foreign-born persons in British Columbia.

SETTING: Provincial tuberculosis (TB) services, British Columbia, Canada. OBJECTIVES: To estimate the risk of drug resistance among foreign-born TB patients and to identify risk factors associated with drug resistance. DESIGN: Using the provincial TB database, we examined all culture-positive foreign-born TB patients for the years 1990-2001. The risk of having a drug-resistant isolate was estimated according to country and region of origin. RESULTS: Of 1940 foreign-born patients identified, 247 (12.7%, 95%CI 11.3-14.3) cases had isolates resistant to at least one of the first-line drugs, with 160 (8.3%) isolates showing monoresistance, 24 (1.2%) multidrug resistance (resistance to at least isoniazid and rifampin) and 63 (3.3%) polyresistance (resistance to two or more drugs, excluding MDR). Country-specific analysis showed that immigrants from Vietnam (adjusted OR 2.12, 95%CI 1.37-3.27) and the Philippines (adjusted OR 1.71, 95%CI 1.10-2.66) had a significantly higher risk of resistance than other immigrants. In addition, the risk was the highest for younger TB patients and patients with reactivated disease (adjusted OR 2.12, 95%CI 1.09-4.09). CONCLUSION: The risk of drug resistance was the highest among foreign-born patients from Vietnam and the Philippines. These findings should assist clinicians in prescribing and tailoring anti-tuberculosis regimens for immigrants more appropriately.

A population-based study of risk factors for drug-resistant TB in British Columbia.

SETTING: Provincial tuberculosis (TB) services, British Columbia, Canada. OBJECTIVE: To investigate risk factors associated with resistance to anti-tuberculosis drugs in British Columbia and to determine if there are differences in risk factor characteristics among different resistance categories. DESIGN: Using population-based data from provincial TB services, all patients with positive culture for Mycobacterium tuberculosis from 1990 to 2001 were identified and included in the study. Logistic regression analyses were performed to assess risk factors for drug resistance. RESULTS: Among 3041 eligible TB cases, 295 (10%) were found to be drug-resistant. Significant risk factors for resistance were younger age, foreign birth, ethnicity, reactivated TB and place of initial diagnosis. Foreign-born subjects (OR 3.18, 95%CI 2.26-4.49) were three times more likely to present with resistance than Canadian-born subjects. Among ethnic groups, Chinese (OR 2.32, 95%CI 1.51-3.57), South-East Asian (OR 2.92, 95%CI 1.88-4.52) and Other Asian subjects (OR 4.40, 95%CI 2.77-7.01) were 2-4 times more likely to present with resistance than Caucasians. Reactivated cases (OR 2.69, 95%CI 1.91-3.77) were three times as likely to have resistance as new cases. CONCLUSION: These results document and quantify the risk of drug-resistant disease in a large population-based cohort, and highlight patient groups who should be identified as at risk for drug-resistant disease in the industrialised world.
