High dose versus low dose standardised cranberry proanthocyanidin extract for the prevention of recurrent urinary tract infection in healthy women : a double-blind randomized controlled trial

Introduction: Les infections urinaires (UTI) sont parmi les infections bactériennes les plus communes chez les femmes. Actuellement, les antibiotiques sont le traitement de choix pour la prévention des UTIs. Pourtant, les produits dérivés de la canneberge sont souvent utilisés avec peu d’évidence de leur efficacité. Notre objectif était d’évaluer l’efficacité d’un extrait de canneberge standardisé en proanthocyanidines de type A (PAC) sur la prévention des UTI à répétition. Méthodes: 145 femmes âgées de 18 ans et plus avec antécédents d’UTI à répétition, définie par ≥ 2 UTIs dans les derniers 6 mois ou ≥ 3 UTIs dans les derniers 12 mois, ont participé à notre essai clinique randomisé à double insu. Soixante-douze femmes ont reçu une dose optimale d’extrait de canneberge quantifié et standardisé en PACs (2 x 18,5 mg PACs par jour) et 73 ont reçu une dose contrôle (2 x 1 mg PACs par jour). L’issue principale était le nombre moyen de nouvelles UTIs symptomatiques chez les participantes durant une période d’intervention de 6 mois. Les issues secondaires étaient : 1) évaluer le nombre moyen d’UTI avec pyurie et avec confirmation microbiologique; 2) décrire les effets secondaires d’une dose quotidienne d’extrait de canneberge. Résultats: Sur la période de suivi de 6 mois, le risque d'UTIs symptomatiques n’était pas significativement différent entre les deux groupes (rapport de taux d’incidence 0,76, 95% IC 0,51-1,11 ; rapport de taux d’incidence ajusté pour l’âge 0,85, 95%IC 0,57-1,26). Parmi les participantes ayant eu moins de 5 UTIs dans l’année précédant leur participation, la prise de 2x18,5 mg était associée à une diminution des UTIs symptomatiques comparativement à une prise de 2x1 mg PACs (rapport de taux d’incidence ajusté pour l’âge 0,57,, 95%IC 0,33-0,99). Aucun effet secondaire majeur n’a été rapporté. Conclusion: La prise d’un extrait de canneberge en teneur élevée de proanthocyanidins n’a pas été associée à une réduction du taux d’incidence d'infections urinaires symptomatiques par rapport à un extrait de proanthocyanidines à faible dose. Nos résultats post-hoc suggèrent que la prise d’une dose de 2x18,5 mg PAC par jour pourrait prévenir les UTIs symptomatiques chez les femmes ayant moins de 5 UTIs par année.Background: Urinary tract infections (UTI) are amongst the most common bacterial infections affecting women. Although antibiotics are the treatment of choice for prevention of UTI, cranberry-derived products are often used by women to prevent UTIs, with limited evidence as to their efficacy. Our objective was to assess the efficacy of a cranberry extract capsule standardized in A-type linkage proanthocyanidins (PACs) for the prevention of recurrent UTI. Methods: 145 women aged 18 years or more with a history of recurrent UTI, defined as ≥ 2 UTIs in the past 6 months or ≥ 3 UTIs in the past 12 months were recruited in this randomized, controlled, double-blind clinical trial. Seventy-three women received an optimal dose of cranberry extract standardized in PACs (2 x 18.5 mg PACs daily) and 72 women received a control dose (2 x 1 mg PACs daily). The primary outcome for the trial was the mean number of new symptomatic UTIs in women during a 6-month intervention period. Secondary outcomes were: 1) To evaluate the mean number of new symptomatic UTIs with pyuria and with microbiological confirmation; 2) To describe the side effects of daily intake of cranberry extract. Results: No significant difference in the risk of UTI during the 24-week follow-up period was found between treatment groups (incidence rate ratio 0.75, 95%CI 0.51-1.11, age-adjusted incidence rate ratio 0.85, 95%CI 0.57-1.26). In women who experienced less than 5 UTIs in the year preceding enrolment, the daily consumption of 2x18.5 mg PACs was associated with a decrease in the risk of symptomatic UTIs reported compared to the control dose (age-adjusted incidence rate ratio 0.57, 95% confidence interval 0.33-0.99). No major side effects were reported. Conclusion: High dose twice daily proanthocyanidin extract was not associated with a reduction in the number of symptomatic urinary tract infections when compared to a low dose proanthocyanidin extract. Our post-hoc results reveal that this high dose of proanthocyanidins may have a preventive impact on symptomatic urinary tract infection recurrence in women who experienced less than 5 infections per year

Role of Endoscopic Third Ventriculostomy in Congenital Obstructive Hydrocephalus

Object:  To improve the care of Obstructive Hydrocephalic infants, from six months to twelve months and to evaluate the efficacy and complications of Endoscopic Third Ventriculostomy (ETV). Materials and Methods:  The study was conducted in the Department of Neurosurgery PGMI, Lahore General Hospital, Lahore from July 2007 to June 2008. Total numbers of patients were 30, which were divided into two equal groups. Group A (15 patients) underwent Endoscopic Third Ventriculostomy (ETV) and Ventriculo-peritoneal VP Shunt were done in Group B (15 patients). Cases were selected randomly. Results:  The mean age for Group A was 9 months and for Group B was 8 months Endoscopic Third Ventriculo-stomy (ETV) procedure found successful in older than 8 months of age while ventriculoperitoneal VP Shunt procedure found successful in all age groups. Before procedure mean head circumference for Group A was 50.86 cm and for Group B was 50.84 cm. After one year follow up mean head circumference in Endoscopic Third Ventriculostomy (ETV) Group was 50.18 cm and in VP Shunt Group was 47.38 cm. Primary success in Endoscopic Third Ventriculostomy (ETV) Group was 53.3% (8 out of 15), whereas in VP Shunt Group it was 66.7% (10 out of 15).  Conclusion:  Although results are same in both groups but Endoscopic Third Ventriculostomy (ETV) Group remain shunt free. Endoscopic Third Ventriculostomy seems to be an effective alternative than VP Shunt in the management of Hydrocephalus in infants provided careful patient selection is done and surgeon is competent enough with Endoscopic Third Ventriculostomy technique

Psychological Assessment of Health Care Workers in Intensive Care Units During the COVID-19 Pandemic

ABSTRACT Background Fear and depression are common to any pandemic particularly in healthcare workers as they are in the front line to treat the diseased. Such a state directly affects the performance of the health system and the patients who are seeking care. This study aimed at assessing the psychological effect of COVID-19 among the healthcare workers in the intensive care units of two tertiary care hospitals of Rawalpindi & Islamabad.   Methods It was a descriptive cross-sectional study, conducted over five months i.e., 1st July 2020 to 1st November 2020. Non-probability consecutive sampling technique was used for recruiting health care workers. PHQ-9 tool was used including 9 questions (items) related to the depression due to COVID-19. Other tool Fear of COVID-19 scale was based on 5 points Likert scale as ‘strongly disagree’, ‘disagree’, ‘neutral’, ‘agree’ and ‘strongly agree’. Besides descriptive frequencies, mean and standard deviation, Spearman correlation (r) was applied to check the correlation between fear of COVID-19 with age (years) and professional experience (years).   Results Out of 382 healthcare workers (doctors, nurses & other staff) recruited in the study, around 50% were found to be suffering from severe depression and have developed a fear of the disease. A significant positive correlation was observed between the age of the healthcare worker and the degree of fear of COVID-19 (p<0.05). Similarly, a significant positive correlation was observed between the number of professional experience and the fear of COVID-19 (p<0.05).   Conclusion It is concluded that healthcare workers in ICU are at risk of depression because of fear of COVID-19. The current situation highlights the areas that need attention. Special training or orientation must be arranged for a situation of an outbreak or a pandemic and skills for keeping one’s psychological wellbeing and mental health must be imparted.

Incidence of Venous Thromboembolism in Critically Ill Coronavirus Disease 2019 Patients Receiving Prophylactic Anticoagulation

This article is made available for unrestricted research re-use and secondary analysis in any form or by any means with acknowledgement of the original source. These permissions are granted for the duration of the World Health Organization (WHO) declaration of COVID-19 as a global pandemic.Objectives: One of the defining features of the novel coronavirus disease 2019 infection has been high rates of venous thromboses. The present study aimed to describe the prevalence of venous thromboembolism in critically ill patients receiving different regimens of prophylactic anticoagulation. Design: Single-center retrospective review using data from patients with confirmed severe acute respiratory syndrome coronavirus 2 requiring intubation. Setting: Tertiary-care center in Indianapolis, IN, United States. Patients: Patients hospitalized at international units Health Methodist Hospital with severe acute respiratory syndrome coronavirus 2 requiring intubation between March 23, 2020, and April 8, 2020, who underwent ultrasound evaluation for venous thrombosis. Interventions: None. Measurements and Main Results: A total of 45 patients were included. Nineteen of 45 patients (42.2%) were found to have deep venous thrombosis. Patients found to have deep venous thrombosis had no difference in time to intubation (p = 0.97) but underwent ultrasound earlier in their hospital course (p = 0.02). Sequential Organ Failure Assessment scores were similar between the groups on day of intubation and day of ultrasound (p = 0.44 and p = 0.07, respectively). d-dimers were markedly higher in patients with deep venous thrombosis, both for maximum value and value on day of ultrasound (p < 0.01 for both). Choice of prophylactic regimen was not related to presence of deep venous thrombosis (p = 0.35). Ultrasound evaluation is recommended if d-dimer is greater than 2,000 ng/mL (sensitivity 95%, specificity 46%) and empiric anticoagulation considered if d-dimer is greater than 5,500 ng/mL (sensitivity 53%, specificity 88%). Conclusions: Deep venous thrombosis is very common in critically ill patients with coronavirus disease 2019. There was no difference in incidence of deep venous thrombosis among different pharmacologic prophylaxis regimens, although our analysis is limited by small sample size. d-dimer values are elevated in the majority of these patients, but there may be thresholds at which screening ultrasound or even empiric systemic anticoagulation is indicated.Dr. Khan’s institution received funding from the National Institutes of Health.

Conceptual framework for a cardiac surgery simulation laboratory and competency-based curriculum in Pakistan - a short innovation report

Simulation is a commonly utilized technique in healthcare education as it provides trainees a realistic, but safe, environment to learn a variety of skills. Trainees belonging to fields known for high stakes with low margins for error, such as cardiac surgery, can greatly benefit from simulation-based education. We propose the establishment of the first multi-tier high fidelity cardiac surgery simulation lab with a structured curriculum that will eventually provide multidisciplinary training to promising cardiac surgeons across Pakistan. The simulation lab may also be used for research, grant acquisition and patent development. Our setup will include the following levels of simulation: a simple bench model, a virtual reality simulator and a unique human performance simulator. Our multitiered approach allows for appropriate sequential trainee skill progression. Finally, we hope that our model inspires the development of similar curricula and modules for trainees belonging to other surgica

FREQUENCY OF BONE FRACTURES DETECTED BY PLAIN RADIOGRAPHY AND KEEPING CT AS GOLD STANDARD

Background: The main cause of bone fracture is traffic accidents are (72.2%), falls (11.6%), blunt injuries are (7.7%) and others (5.8%)). About 84 patients were included in our studies. Out of which 21 (25.0%) were females and 63(75.0%) were males. Objective: The objective of this study is to evaluate the frequency of bone fractures detected by plain radiography and keeping CT as gold standard. Methodology: In our cross-sectional study all the patients with fracture undergoing CT and X-Ray were included. Patients with bone surgery were excluded as well as patients who declined to give consent and those who were uncooperative were all excluded. X-ray performed for all the fractures and the complex one sent to CT. The consent form was obtained by patients in this study. We reviewed our data of patients who underwent CT and X-ray. CT (Toshiba 64) was performed from the exact area of fracture and images reconstructed at 3mm and for reporting 5mm for filming. X-ray performed according to the appropriate range of kVp and mAs. All findings of CT were considered by the advice of consultant radiologist. Data was represented with means of standard deviation of frequency and percentage where appropriate. Chi square testing was used to compare CT and X-ray qualitative data. Data was entered into IBM SPSS Statistics 24.0. P-value &lt;0.05 considered the significant. Results: In our study 84 patients were included. Out of which 21 (25.0%) were females and 63 (75.0%) were males and the standard deviation was 0.436. There causes of fracture were 18(21.4%) injury, 8(9.5%) were compression fractures, 54(64.3%) RTA, 2(2.4%) pathologic fractures and 1(1.2%) was sports injury fracture and the standard deviation was .997. Conclusion: Our study concluded that the bone fractures are more common in males than females. The most common cause of bone fractures is RTA (Road Traffic Accidents). Study also concludes that most common type of bone fracture is Transverse bone fracture. CT was more efficient in detecting bone fractures than plain radiography because more fractures were detected on CT than plain radiography.

A nationwide virtual research education program for medical students in Pakistan: Methodological framework, feasibility testing, and outcomes

Introduction: Equipping young medical trainees with fundamental research skills can be a promising strategy to address the need for professionals who can understand and responsibly communicate evolving scientific evidence during a pandemic. Despite an ardent interest to partake in research, most educational institutions in Pakistan and other low-middle income countries have not yet adopted a comprehensive strategy for research skills education. The authors aimed to design and assess the feasibility of implementing the first nation-wide virtual research workshop for medical students in Pakistan. Methods: The course Beginners Guide to Research, designed as a nation-wide virtual research workshop series, was conducted for medical students across Pakistan in June 2020. Four interactive live workshops took place online on alternate days from June 22nd, 2020, to June 27th, 2020, each lasting 1-2 h. Outcomes included: (i) reach, (ii) efficacy as indexed by pre-post change in score pertaining to knowledge and application of research and (iii) self-rated perceptions about understanding of research on a Likert scale. Results: 3,862 participants enrolled from 41 cities and 123 institutions. Enrolled participants belonged to the following provinces: Sindh (n = 1,852, 48.0%), Punjab (n = 1,767, 45.8%), Khyber Pakhtunkhwa (n = 109, 2.8%), Azad Jammu and Kashmir (n = 84, 2.2%) Balochistan (n = 42, 1.1%). We also saw a few registrations from international students (n = 8, 0.2%). Mean (SD) age of enrolled medical students was 21.1 (2.1) years, 2,453 (63.5%) participants were female and 2,394 (62.0%) were from private-sector medical colleges. Two thousand ninety-three participants participants filled out all four pre-test and post-test forms. The total median knowledge score improved from 39.7 to 60.3% with the highest improvements in concepts of research bioethics and literature search (p \u3c 0.001) with greater change for females compared to males (+20.6 vs. +16.2%, p \u3c 0.001) and private institutions compared to public ones (+16.2 vs. +22.1%, p \u3c 0.001). Conclusion: The overwhelming enrollment and significant improvement in learning outcomes (\u3e50% of baseline) indicate feasibility of a medical student-led research course during a pandemic, highlighting its role in catering to the research needs in the LMICs
