Vaginal Uncomplicated Delivery Rate as a Quality Indicator Compared to Cesarean Delivery Rate: A Quantitative Analysis of a Population Database.

OBJECTIVE: The objective of this study is comparing the vaginal uncomplicated delivery (VUD) rate, defined as all vaginal deliveries (including forceps and vacuum) without an adverse maternal or neonatal labour outcome, to the cesarean delivery (CD) rate, as a performance indicator. METHODS: This is a retrospective cohort analysis from a provincial database of all term deliveries by an obstetrician in a single year, excluding diagnoses preventing active labour. Most obstetricians in this jurisdiction practice consultative obstetrics, focused on supporting primary maternity care. We investigated the association of adverse delivery (AD), measured by the adverse outcome index (AOI), with CD and VUD rates. RESULTS: We report 16 620 deliveries by 210 obstetricians, with a vaginal delivery rate of 39.6%, of which 36.6% were operative vaginal delivery. The overall AD rate was 9.9%, and the overall VUD rate was 34%. While the CD and VUD both correlated with mode of delivery, only the VUD rate was correlated to the AD rate. CONCLUSIONS: Quality assurance in obstetrics must balance the needs of two patients based on limited data. Our data shows the shortcomings of the prevailing performance indicator, CD rate, which does not correlate with birth outcomes for the pregnant patient or infant. The VUD rate provides an alternative that assesses both mode of delivery and labour outcomes. Shifting the quality lens to focus on VUD rate will provide a better metric that measures optimal outcomes for pregnant people and their babies. OBJECTIF: Cette étude vise à comparer le taux d'accouchement vaginal sans complications (AVSC), défini comme la proportion d'accouchements vaginaux (y compris par forceps ou ventouse) sans issue maternelle ou néonatale défavorable, au taux de césariennes en tant qu'indicateur de performance. MéTHODE: Il s'agit d'une analyse de cohorte rétrospective de données extraites d'une base de données provinciale sur tous les accouchements à terme pratiqués par un obstétricien dans une année, à l'exclusion des diagnostics empêchant le travail actif. La plupart des obstétriciens de cette province ont une pratique de consultation en obstétrique, principalement pour la prestation de soins de maternité primaires. Nous avons étudié la corrélation du taux d'événements indésirables (EI) à l'accouchement, mesuré par l'indice des issues défavorables (AOI), avec le taux de césariennes et le taux d'AVSC. RéSULTATS: Nous avons recensé 16 620 accouchements réalisés par 210 obstétriciens, pour un taux d'accouchement vaginal de 39,6 %; de ces accouchements vaginaux, 36,6 % étaient des accouchements assistés. Le taux global d'EI était de 9,9 %; le taux global d'AVSC, de 34 %. Alors que la césarienne et l'AVSC sont tous deux corrélés avec le mode d'accouchement, seul le taux d'AVSC est corrélé avec le taux d'EI. CONCLUSIONS: L'assurance de la qualité en obstétrique doit trouver un équilibre entre les besoins de deux patientes sur la base de données limitées. Nos données montrent les lacunes du taux de césariennes comme indicateur de performance dominant, car ce taux n'est pas corrélé avec les issues maternelles ou néonatales. Le taux d'AVSC serait une meilleure option, car il évalue à la fois le mode d'accouchement et les issues de l'accouchement. En considérant la qualité des soins à travers le prisme du taux d'AVSC, on obtiendrait un meilleur indicateur des issues optimales pour les personnes enceintes et leurs bébés.

Reoperation and pain-related outcomes after hysterectomy for endometriosis by oophorectomy status.

BACKGROUND: More research is needed that compares the outcomes between those who underwent a hysterectomy for endometriosis with conservation of one or both ovaries and those who underwent a hysterectomy with bilateral salpingo-oophorectomy. OBJECTIVE: This study aimed to compare the rate and types of reoperations (primary outcome) and use of other pain-related health services (secondary outcomes) among people who underwent a hysterectomy with conservation of both ovaries, those who underwent a hysterectomy with unilateral salpingo-oophorectomy, and those who underwent a hysterectomy with bilateral salpingo-oophorectomy. STUDY DESIGN: This was a population-based, retrospective cohort study of 4489 patients aged 19 to 50 years in British Columbia, Canada, who underwent a hysterectomy for endometriosis between 2001 and 2016. Index surgeries were classified as hysterectomy alone (conservation of both ovaries), hysterectomy with unilateral salpingo-oophorectomy, or hysterectomy with bilateral salpingo-oophorectomy. Reoperation rate was the primary outcome. Secondary outcomes (measured at 3-12 months and 1-5 years after hysterectomy) included physician visits for endometriosis and pelvic pain, prescriptions filled for opioids, and use of hormonal suppression medications and hormone replacement therapy. RESULTS: Reoperation rates were low across all groups, with 89.5% of all patients remaining reoperation free by the end of follow-up (median of 10 years; interquartile range, 6.1-14.3 years). Patients who underwent a hysterectomy alone were more likely to undergo at least 1 reoperation when compared with those who underwent a hysterectomy with bilateral salpingo-oophorectomy (13% vs 5%; P<.0001), most commonly an oophorectomy or adhesiolysis. When oophorectomy as reoperation was removed in a sensitivity analysis, this difference was partially attenuated (6% of hysterectomy alone group vs 3% of hysterectomy with bilateral salpingo-oophorectomy group undergoing at least 1 reoperation). All groups were very similar in terms of rates of physician visits for endometriosis or pelvic pain and the number of days of opioid prescriptions filled. Furthermore, the rate of hormonal suppression medication use was similar among the groups, whereas the rate of prescriptions filled for hormone replacement therapy after hysterectomy with bilateral salpingo-oophorectomy was 60.6% of patients who filled at least 1 prescription at 3 to 12 months after index surgery. CONCLUSION: Patients who underwent a hysterectomy with bilateral salpingo-oophorectomy had a lower reoperation rate than those who underwent a hysterectomy with conservation of one or both ovaries. However, there was little difference between the groups for the secondary outcomes measured, including physician visits for endometriosis and pelvic pain, opioid use, and use of hormonal suppression medications, suggesting that persistent pelvic pain after hysterectomy for endometriosis may not differ substantively based on ovarian conservation status. One limitation was the inability to stratify patients by stage of endometriosis or to determine the impact of endometriosis stage or the presence of adnexal disease or deep endometriosis on the outcomes. Moreover, hormone replacement therapy prescriptions was not filled by about 40% of patients after hysterectomy with bilateral salpingo-oophorectomy, which may have significant health consequences for these individuals undergoing premature surgical menopause. Therefore, strong consideration should be given to ovarian conservation at the time of hysterectomy for endometriosis.

Opportunistic Salpingectomy Between 2017 and 2020: A Descriptive Analysis.

OBJECTIVES: Opportunistic salpingectomy (OS) is the removal of fallopian tubes during another pelvic surgery for the purpose of ovarian cancer prevention. Herein, we describe the rates of OS at the time of hysterectomy and tubal sterilization between 2017 and 2020. METHODS: This study uses the Canadian Institute of Health Information's Discharge Abstract Database and National Ambulatory Care Reporting System for all Canadian provinces and territories except for Quebec between the fiscal years 2017 and 2020. A descriptive analysis on all people aged 15 years and older who had hysterectomies or tubal sterilizations was conducted to determine the proportion of hysterectomies that included bilateral salpingectomy (OS) and the proportion of tubal sterilizations that were OS compared to tubal ligation. RESULTS: There were 174 006 people included in the study. The proportion of hysterectomies that included OS increased from 31.7% in 2017 to 39.9% by 2020. With respect to tubal sterilizations, rates of OS increased from 26.3% of all tubal sterilizations in 2017 to 42.5% in 2020. British Columbia remained the jurisdiction with the highest rates of OS, but rates increased significantly in many jurisdictions, particularly at the time of tubal sterilization. CONCLUSION: The rates of OS have continued to increase in all Canadian jurisdictions following the official Society of Obstetricians and Gynaecologists of Canada recommendation to consider OS in 2015. Assuming that all tubal ligations could have been OS and 75% of hysterectomies with ovarian conservation could have included OS, our data indicate 76 932 missed opportunities for ovarian cancer prevention.

Case-Fatality and Functional Outcome after Subarachnoid Hemorrhage (SAH) in INternational STRoke oUtComes sTudy (INSTRUCT).

BACKGROUND: There are few large population-based studies of outcomes after subarachnoid hemorrhage (SAH) than other stroke types. METHODS: We pooled data from 13 population-based stroke incidence studies (10 studies from the INternational STRroke oUtComes sTudy (INSTRUCT) and 3 new studies; N=657). Primary outcomes were case-fatality and functional outcome (modified Rankin scale score 3-5 [poor] vs. 0-2 [good]). Harmonized patient-level factors included age, sex, health behaviours (e.g. current smoking at baseline), comorbidities (e.g.history of hypertension), baseline stroke severity (e.g. NIHSS >7) and year of stroke. We estimated predictors of case-fatality and functional outcome using Poisson regression and generalized estimating equations using log-binomial models respectively at multiple timepoints. RESULTS: Case-fatality rate was 33% at 1 month, 43% at 1 year, and 47% at 5 years. Poor functional outcome was present in 27% of survivors at 1 month and 15% at 1 year. In multivariable analysis, predictors of death at 1-month were age (per decade increase MRR 1.14 [1.07-1.22]) and SAH severity (MRR 1.87 [1.50-2.33]); at 1 year were age (MRR 1.53 [1.34-1.56]), current smoking (MRR 1.82 [1.20-2.72]) and SAH severity (MRR 3.00 [2.06-4.33]) and; at 5 years were age (MRR 1.63 [1.45-1.84]), current smoking (MRR 2.29 [1.54-3.46]) and severity of SAH (MRR 2.10 [1.44-3.05]). Predictors of poor functional outcome at 1 month were age (per decade increase RR 1.32 [1.11-1.56]) and SAH severity (RR 1.85 [1.06-3.23]), and SAH severity (RR 7.09 [3.17-15.85]) at 1 year. CONCLUSION: Although age is a non-modifiable risk factor for poor outcomes after SAH, however, severity of SAH and smoking are potential targets to improve the outcomes.

Risk of cardiovascular disease among women carrying BRCA mutations after risk-reducing bilateral salpingo-oophorectomy: A population-based study.

OBJECTIVE: Examine the risk of cardiovascular disease (CVD) following risk reducing bilateral salpingo-oophorectomy (RRBSO) among women with BRCA mutations. METHODS: In this retrospective population-based study in British Columbia, Canada, between 1996 and 2017, we compared the risk of CVD among women with known BRCA mutations who underwent RRBSO before the age of 50 (n = 360) with two groups of age-matched women without known BRCA mutations: 1) women who underwent bilateral oophorectomy (BO) for benign conditions (n = 3600); and, 2) women with intact ovaries who had hysterectomy or salpingectomy (n = 3600). Our primary outcome was CVD (a composite (any of) myocardial infarction, heart failure, and/or cerebrovascular disease). Secondary outcomes included a diagnostic code for predisposing conditions (hypertension, dyslipidemia, and/or diabetes mellitus), and use of cardioprotective medications (statins and/or beta-blockers). RESULTS: We report no significant increased risk for CVD between women with BRCA mutations and women who underwent BO (aHR = 1.08, 95%CI: 0.72-1.62), but women with BRCA mutations were less likely to be diagnosed with predisposing conditions (aHR = 0.69, 95%CI: 0.55-0.85). Compared to women without BRCA mutations with intact ovaries who underwent hysterectomy or salpingectomy, women with BRCA mutations had significantly increased risk for CVD (aHR = 1.82, 95%CI: 1.18-2.79) and were less likely to be diagnosed with predisposing conditions (aHR = 0.78, 95%CI: 0.62-0.97) and to fill cardioprotective medications (aHR = 0.88, 95%CI: 0.64-1.22). CONCLUSION: Our results suggest an opportunity for improved prevention of CVD in women with BRCA mutations after prophylactic oophorectomy. Despite the observed lower prevalence of predisposing conditions for CVD and lesser use of cardioprotective medications, this population did not have a lower rate of CVD.

Cardiovascular medications and survival in people with ovarian cancer: A population-based cohort study from British Columbia, Canada.

OBJECTIVES: Research examining survival among people with ovarian cancer following use of statins or ß-blockers has been conflicting. Many studies to date have suffered from immortal time bias and/or had limited power. To address these limitations, we used time-dependent analyses to study the association between statin or ß-blocker use among all people diagnosed with an epithelial ovarian cancer in British Columbia, Canada between 1997 and 2015. METHODS: Population-based administrative data were linked for 4207 people with ovarian cancer. Statin or ß-blocker use was examined using time-dependent variables for any use, cumulative duration of use and by user-group according to whether use was initiated before or after their ovarian cancer diagnosis. Cox proportional hazards models were run to estimate the association between statin or ß-blocker use and survival. RESULTS: Any postdiagnosis use of statins was associated with better ovarian cancer survival in the full cohort (adjusted hazard ratio (aHR) = 0.76, 95% CI 0.64, 0.89) and among women with serous cancers (aHR = 0.80, 95%CI 0.67-0.96). This was primarily driven by new use post-diagnosis (aHR = 0.67, 95%CI, 0.51-0.89), but there was a trend towards better survival among those who continued use from before diagnosis (aHR 0.83, 95%CI, 0.68-1.00). There was no statistically significant association between ß-blocker use and survival. CONCLUSION: Postdiagnosis statin use was associated with improved survival among people with ovarian cancer. Given the consistency of this finding in the literature, we recommend a randomized clinical trial of statin use in people with ovarian cancer.

Establishment of population-based stroke registry in Ludhiana city, northwest India: feasibility and methodology.

BACKGROUND/AIMS: The Indian Council of Medical Research (ICMR) initiated the Task Force Project to evaluate the feasibility of conducting a population-based stroke registry in Ludhiana city, Punjab, Northwest India. METHODS: All first-ever, stroke patients over 18 years from the city of Ludhiana were included in the study from March 26th 2010 to March 25th 2011. Stroke information was collected based on the WHO STEPS approach from the participating hospitals, scan centres and doctors. Modified Rankin Scale (mRS) was administered by telephonic interview at 28 days after stroke. The information on stroke deaths was obtained from the Municipal Corporation (MC) office. RESULTS: A total of 905 first-ever stroke patients were documented. After excluding duplicate cases and patients from outside the city, 493 patients were included. The practical issues identified in data collection from these centres were reluctance to take informed consent, lack of willingness to share the data, difficulty to identify key persons from each centre, retrieving medical records from public hospitals and poor documentation of deaths in MC office. CONCLUSION: Population-based stroke registry was feasible in an urban population with the above methodology. The issues related to feasibility were identified and necessary changes were made for the main phase of the registry.

Palladium­zinc ferrite varnished hydroxyapatite spherocuboids for electrochemical detection of carcinogenic food preservatives.

The demand for processed foods relies heavily on synthetic antioxidants like TBHQ and BHA to prevent spoilage. However, their excessive use poses health risks, prompting regulatory measures in many countries to ensure food safety. In this concern, a proficient electrochemical sensor for the simultaneous detection of tert-butylhydroquinone (TBHQ) and butylated hydroxyanisole (BHA) was designed. A comparatively greener hydroxyapatite (HAP) supported zinc ferrite (ZF) nanosensor was developed with conducting coating of Pd nanoparticles. A consolidated and mechanistic approach was opted to reduce the band gap and agglomeration the magnetic ZF nanoparticles. The interesting spherocuboidal morphology of the synthesized nanocomposite with good porosity enhanced the detection performance of the sensor. The proposed platform displayed good detection limits of both TBHQ and BHA (0.73 and 5.6 nM for TBHQ and BHA, respectively). The nanosensor successfully detected TBHQ and BHA in food samples proved its potential for the development of commercially competitive sensor.

Rational design of Boerhavia diffusa derived CoFe2O4-Carbon dots@Boehmite platform for photocatalysis and ultra trace monitoring of hazardous pesticide and UO22+ ions.

In view of exploiting natural resources for designing of effectual materials in favor of detection and obliteration of water pollutants, a fluorescent nanomaterial (CDBHCF) based on biomass derived carbon dots (CDs) was constructed. The CDs and cobalt ferrite (CF) particles were anchored on boehmite (BH) which served as a support material for CDs. The CDBHCF nanocomposite was prepared via facile hydrothermal treatment for selective recognition of Methyl parathion (MP) pesticide and uranyl ions (UO22+). The corresponding structural, morphological and opto-electronic properties of the nanomaterials have been investigated by different physicochemical techniques. The fluorescent CDBHCF probe was employed to detect extremely low concentration of MP and UO22+ with detection limit of 22.4 nM and 4.4 nM, respectively. Ultimately, the proposed sensing platform was validated through real sample analysis. Besides, CDBHCF nanocomposite was utilized for photocatalytic abolition of Tetracycline (TC) in water samples. Initially, the impact of various operational parameters on the degradation efficiency, including catalyst dosage and initial pH were thoroughly examined. Under optimized conditions, the fabricated CDBHCF nanocomposite demonstrated excellent results for photocatalytic degradation of TC (92 % degradation in 120 min) under visible light illumination. Thus, the proposed strategy delivered an innovative insight for dual purpose of CDBHCF nanocomposite: as a fluorescent probe for real time monitoring and as a photocatalyst for removal of pollutants via simple photocatalytic degradation.

Metformin use and survival in people with ovarian cancer: A population-based cohort study from British Columbia, Canada.

OBJECTIVES: There is an active debate regarding whether metformin use improves survival in people with ovarian cancer. We examined this issue using methods designed to avoid immortal time bias-as bias that occurs when participants in a study cannot experience the outcome for a certain portion of the study time. METHODS: We used time-dependent analyses to study the association between metformin use for all 4,951 patients diagnosed with ovarian cancer in 1997 through 2018 in the province of British Columbia, Canada. Cox proportional hazards models were run to estimate the association between metformin and survival in the full cohort of ovarian cancer patients and among a cohort restricted to patients with diabetes. RESULTS: Metformin use was associated with a 17 % better ovarian cancer survival in the full cohort (adjusted hazard ratio (aHR) = 0.83 (95 %CI 0.67, 1.02)), and a 16 % better ovarian cancer survival for serous cancers patient's cohort (aHR = 0.84 (95 %CI 0.66, 1.07)), although both were not significant. However, a statistically significant protective effect was observed when restricting to the diabetic cohort (aHR = 0.71 (95 %CI 0.54-0.91)), which was also seen among serous cancers (aHR = 0.73 (95 %CI 0.54-0.98)). CONCLUSION: Metformin use was associated with improved ovarian cancer survival. The lack of statistical significance in the full cohort may reflect that diabetes is associated with reduced cancer survival, and thus diabetes itself may offset the benefit of metformin when examining the full cohort. Future research should examine metformin use among non-diabetic ovarian cancer patients.

Dietary patterns in stroke patients in Northwest India.

OBJECTIVES: Little is known about the dietary patterns among stroke patients in India. We explored the dietary patterns in stroke patients and attempted to correlate the dietary patterns with stroke characteristics. METHODS: This hospital-based study was carried out in a tertiary referral centre in Northwest India from March 2008 to September 2009. All first ever stroke (ischaemic and hemorrhagic) patients were interviewed by the dietician using an oral diet questionnaire. The demographic information and risk factors were noted and outcome was assessed after 30 days using modified Rankin scale (≤2 = good outcome). RESULTS: A total of 210 stroke patients were enrolled. The mean age was 60 ± 14 years and 126 (60%) patients were men. Hypertension (167 (79.5%)) was the major risk factor. All patients consumed cereals and beverages. Consumption of other food items in the diet were as follows: milk and milk products (203 (96.7%)), saturated fats (butter, butter oil, cream) (133 (63.3%)), bakery items (139 (66.2%)), fried snacks (116 (55.2%)), fruits (96 (45.7%)), and juices (20 (9.5%)). Large proportion of the patients (112 (53.6%)) consumed more food calories than recommended. Use of fried snacks was significant in patients who consumed alcohol (P = 0.03) and patients who had diabetes mellitus were more likely to use saturated fats (P = 0.01). DISCUSSION: Majority of the patients consumed milk and milk products. Fruits and juices were consumed by a small proportion of patients. Our results provide opportunities for stroke prevention by diet modification.

Cost of stroke from a tertiary center in northwest India.

AIM: We aimed to study the cost of stroke, its predictors, and the impact on social determinants of the family. SETTINGS AND DESIGN: This prospective study was done in the Stroke unit and Neurology clinic between April 2009 and October 2011. MATERIALS AND METHODS: All first ever stroke patients during the study period were enrolled. Direct and indirect costs at admission, at 1 and 6 months follow-up were obtained. The follow-up included information about the patient's poststroke outcome using modified Rankin Scale (mRS), work status, modifications made at home, loan requirement, etc., RESULTS: Two hundred patients were enrolled in this study and final analysis was performed on 189 patients. The mean age was 58 ± 13 years and 128 (67.7%) were men. Majority (54%) were living in a joint family. The mean overall cost of stroke per patient was rupees (INR) 80612 at 6 months. Higher income (P = 0.008), poor outcome (mRS >2) (P = 0.001), and length of hospital stay (P = 0.001) were the cost driving factors of total cost of stroke at 6 months. There was a decline in the requirement of help (P < 0.0001) and need for loan (P = 0.003) at 6 months follow-up. CONCLUSIONS: Direct medical cost or acute care of stroke accounted for a major component of cost of stroke. Poor outcome, length of hospital stay, and higher income were the cost driving factors. The socioeconomic impact on the family decreased at follow up probably due to joint family system.

Appraising the electrocatalytic performance of beta-cyclodextrin embellished supramolecular recognition system for pernicious food colorants.

The current research presents the evaluation of supramolecular proficiency of the designed platform for electrocatalytic determination of pernicious food colorants, amaranth and fast green. The approach involving surface modification of glassy carbon electrode with beta cyclodextrin decorated strontium ferrite reduced graphene oxide nanocomposite (SFrGO-ßCD) to ensure fast and reversible electro-oxidation of hydroxyl groups of the colorant molecules. The synergy between SF and rGO facilitated the sensor with enhanced surface area and conductivity through faradic redox reaction. Tremendous decrease in the obtained values of peak separation potential and impedance as manifested in CV and EIS analysis, enabled by electrostatic interactions between surface functionalities of rGO and ßCD has resulted in the significant augmentation of sensitivity. The value of charge transfer coefficient, number of electrons involved, nature of electron transport process at electrode electrolyte interface during the analysis of electrochemical detection were explored through CV experiments. Food samples analysis (without spiking) utilizing screen printed electrode manifested the sensor as portable device for real time monitoring. Outstanding detection limit (0.022 nM for amaranth and 0.051 nM for fast green), excellent regenerability (Relative standard deviation less than 3%) and apparent recovery rate (above 90%) of the modified electrode presented a colossal potential for the development of sustainable and commercially competitive electrochemical sensor in food sector.

Complementary and alternative medicine treatments among stroke patients in India.

BACKGROUND: Complementary and alternative medicine (CAM) is commonly used by persons with stroke throughout the world, particularly in Asia. OBJECTIVE: The objectives of this study were to determine the frequency of CAM use and the factors that predict the use of CAM in stroke patients. METHODS: This study was carried out in the stroke units of Christian Medical College, Ludhiana, and Sree Chitra Tirunal Institute for Medical Sciences and Technology, Thiruvananthapuram, India, from June 2010 to December 2010. Participants were interviewed using a structured questionnaire (≥ 6 months post stroke). Outcomes were assessed using a modified Rankin Scale (mRS). RESULTS: Three hundred fourteen stroke patients were interviewed; mean age was 57.4 ± 12.9 years, and 230 (73.2%) patients were men. Of 314 patients, 114 (36.3%) had used the following CAM treatments: ayurvedic massage, 67 (59.3%); intravenous fluids, 22 (19.5%); herbal medicines, 17 (15%); homeopathy, 15 (13.3%); witchcraft, 3 (2.7%); acupuncture, 3 (2.7%); opium intake, 10 (8.8%); and other nonconventional treatments, 10 (8.8%). Patients with severe stroke (P < .0001), limb weakness (P < .0001), dysphagia (P = .02), dyslipidemia (P = .007), hypertension (P = .03), or hemorrhagic stroke (P<.0001) and patients with poor outcome (mRS >2;P < .0001) often used CAM treatments. CONCLUSION: More than one-third of the patients in this study opted for CAM. Presence of limb weakness, dysphagia, dyslipidemia, hypertension, hemorrhagic stroke, severe stroke, and poor outcome predicted the use of CAM.

Epidemiology of Young Stroke in the Ludhiana Population-Based Stroke Registry.

Objective: The objective of the study was to determine incidence, risk factors, and short-term outcomes of young stroke in Ludhiana city, Northwest India. Methods: Data were collected on first-ever stroke in patients of age ≥18 years, from hospitals, diagnostic imaging centers, general practitioners, and municipal corporation during March 2011-March 2013 in Ludhiana city, using the World Health Organization Stepwise Approach to Surveillance (WHO STEPS). Outcome was documented using the modified Rankin Scale at 28 days. Results: Of 2948 patients, 700 (24%) were in the age group 18-49 years. Annual incidence in this age group was 46/100,000 person-years (95% confidence interval [CI], 41-51/100,000). Hypertension (84%), diabetes mellitus (48%), and atrial fibrillation (AF) (12%) were found more common in >49 years age group, as compared with 18-49 years age group. Drug abuse (8.7% vs. 6% in age >49 years; P = 0.04) and tobacco intake (8.7% vs. 5.6% in age >49 years; P = 0.02) was more common in young people, that is, 18-49 years age group in comparison to older patients, >49 years age group. Recovery was better in younger subjects (60% vs. 46% in age >49 years P < 0.001). In a multivariable analysis, younger people were more often literate (odds ratio [OR] 2.52; 95% CI, 1.68-3.77; P < 0.001), employed (OR 3.92; 95% CI, 2.20-5.21; P < 0.001), and 374 (60%) had good clinical outcome, modified Rankin Scale <2 at 28 days follow-up as compared with 938 (46%) older patients (OR 1.52; 95% CI, 1.15-2.00; P = 0.003). Conclusion: Hypertension, diabetes mellitus, drug addiction, and tobacco intake were significantly associated with young stroke. Outcome was also better in younger people.

Microbe mediated remediation of dyes, explosive waste and polyaromatic hydrocarbons, pesticides and pharmaceuticals.

Industrialization and human activities have led to serious effects on environment. With the progress taking place in the biodegradation field, it is important to summarize the latest advancement. In this review, we intend to provide insights on the recent progress on the biodegradation of environmental contaminants such as dyes, pesticides, pharmaceuticals, explosive waste and polyaromatic hydrocarbons by microorganisms. Along with the biodegradation of environmental contaminants, toxicity effects have also been discussed.

Bone health after RRBSO among BRCA1/2 mutation carriers: a population-based study.

OBJECTIVE: Examine the risks of fractures and osteoporosis after risk-reducing bilateral salpingo-oophorectomy (RRBSO) among women with BRCA1/2 mutations. METHODS: In this retrospective population-based study in British Columbia, Canada, between 1996 to 2017, we compared risks of osteoporosis and fractures among women with BRCA1/2 mutations who underwent RRBSO before the age of 50 (n=329) with two age-matched groups without known mutations: 1) women who underwent bilateral oophorectomy (BO) (n=3,290); 2) women with intact ovaries who had hysterectomy or salpingectomy (n=3,290). Secondary outcomes were: having dual-energy X-ray absorptiometry (DEXA) scan, and bisphosphonates use. RESULTS: The mean age at RRBSO was 42.4 years (range, 26-49) and the median follow-up for women with BRCA1/2 mutations was 6.9 years (range, 1.1-19.9). There was no increased hazard of fractures for women with BRCA1/2 mutations (adjusted hazard ratio [aHR]=0.80; 95% confidence interval [CI]=0.56-1.14 compared to women who had BO; aHR=1.02; 95% CI=0.65-1.61 compared to women with intact ovaries). Among women who had DEXA-scan, those with BRCA1/2 mutations had higher risk of osteoporosis (aHR=1.60; 95% CI=1.00-2.54 compared to women who had BO; aHR=2.49; 95% CI=1.44-4.28 compared to women with intact ovaries). Women with BRCA1/2 mutations were more likely to get DEXA-scan than either control groups, but only 46% of them were screened. Of the women with BRCA1/2 mutations diagnosed with osteoporosis, 36% received bisphosphonates. CONCLUSION: Women with BRCA1/2 mutations had higher risk of osteoporosis after RRBSO, but were not at increased risk of fractures during our follow-up. Low rates of DEXA-scan and bisphosphonates use indicate we can improve prevention of bone loss.

Transient Ischemic Attack (TIA) Incidence with Geographic Information Systems (GIS) Mapping for Stroke Prevention Interventions.

OBJECTIVES: GIS mapping as a public health tool has been increasingly applied to chronic disease control. While evaluating TIA incidence from an existing regional stroke registry in Ludhiana city, India, we aim to apply the innovative concept of regional TIA GIS mapping for planning targeted stroke prevention interventions. METHODS: TIA patient data was obtained from hospitals, scan centers and general practitioners from March 2010 to March 2013 using WHO-Stroke STEPS based surveillance as part of establishing a population-based stroke registry in Ludhiana city. From this registry, patients with TIA (diagnosed by MRI image-based stroke rule-out, or clinically) were chosen and data analyzed. RESULTS: A total of 138 TIA patients were included in the final analysis. The annual TIA incidence rate for Ludhiana city was 7.13/100,000 (95% confidence interval: 5.52 to 8.74) for 2012-2013. Mean age was 58.5 ± 13.9 years (range: 22-88 years) and 87 (63%) were men. Majority of the TIA cases had anterior circulation TIAs. Hypertension (87.4%) was the most common risk factor. Using Geographic Information System (GIS) mapping, high TIA incidence was seen in central, western, and southern parts and clustering of TIA cumulative incidence was seen in the central part of Ludhiana city. CONCLUSION: Incidence rate of TIA was lower than that expected from a low- and middle-income country (LMIC). TIA GIS mapping, looking at regional localization, can be a novel option for developing targeted, cost-effective stroke prevention programs.

Assessment of malnutrition and enteral feeding practices in the critically ill: A single-centre observational study.

BACKGROUND AND AIMS: Early identification of malnutrition among hospitalised patients is essential to institute appropriate patient-specific nutritional strategies. This study was conducted to evaluate the nutritional status of medical patients at admission to the adult intensive care unit (ICU) and to identify factors which prevent attainment of daily feeding goals in them. METHODS: This was a 1 year prospective, observational study on 200 medical adult ICU patients. The study was carried out based on daily documentation. The primary outcome was the nutritional status of medical Patients at admission to the adult ICU. The tests for statistical analysis used were independent t test, Chi-square test, Fisher's exact test and multivariate logistic regression analysis. RESULTS: Out of the 200 patients in our study, 45%, 48.5% and 9% of patients had mild, moderate and severe malnutrition, respectively, corresponding to subjective global assessment (SGA) rating A,B and C, respectively. The most common reasons for non-attainment of daily feeding goals were delayed feed procurement (17.57%), and feeds being held for procedures (16.36%). The overall mean length of ICU stay was 8.63 ± 7.26 days, and the ICU mortality rate was 47.5% (95/200). Patients with SGA rating B and C at admission had higher risk of mortality in the ICU, with an adjusted odds ratio of 3.54 (95% confidence interval [CI]- 1.71-7.33, P = 0.001) and 11.11 (95% CI-2.26-54.66, P = 0.003), respectively. CONCLUSION: Malnutrition is commonly present at admission among medical ICU patients, and is associated with higher ICU mortality.

Stroke profile and outcome between urban and rural regions of Northwest India: Data from Ludhiana population-based stroke registry.

INTRODUCTION: The objective of this study is to compare the clinical profile, risk factors, type and outcome of stroke patients in urban and rural areas of Punjab, India. METHODS: The primary data source was from the Ludhiana urban population-based stroke registry. The data of first-ever stroke patients with age ≥18 years were collected using WHO stepwise approach from all hospitals, general practitioners, physiotherapy and scan centres between 26 March 2011 and 25 March 2013. RESULTS: A total of 4989 patients were included and out of 4989 patients, 3469 (69%) were from urban areas. Haemorrhagic stroke was seen more in rural as compared to urban regions (urban 1104 (32%) versus rural 552 (36%); p = 0.01). There were significant differences seen in stroke risk factors; hypertension (urban 1923 (84%) versus rural 926 (89%); p = 0.001) and hyperlipidaemia (urban 397 (18%) versus rural 234 (23%); p = 0.001) between two groups. In the multivariable analysis the rural patients were more likely to be younger (age < 40 years) (OR: 1.82; 95% CI: 1.24-2.68; p = 0.002), Sikhs (OR: 2.57; 95% CI: 1.26-5.22; p = 0.009), farmers (OR: 9.41; 95% CI: 5.36-16.50; p < 0.001), housewives (OR: 2.71; 95% CI: 1.45-5.06; p = 0.002), and consumed alcohol (OR: 1.57; 95% CI: 1.19-2.06; p = 0.001) as compared to urban patients. In addition, use of imaging was higher in rural patients (OR: 1.99; 95% CI: 1.06-3.74; p = 0.03) as compared to urban patients. DISCUSSION AND CONCLUSION: In this large cohort of patients, rural and urban differences were seen in risk factors and type of stroke. Stroke prevention strategies need to take into consideration these factors including regional sociocultural practices.
