Introduction Hysterectomy is a common surgical procedure in women, and oophorectomy may also be performed with the hysterectomy. The objective of this study was to identify clinical indications and pathological findings in hysterectomies, performed for gynecological causes, in women of reproductive age (15-49 years) and to determine if oophorectomy or ovarian conservation was performed with the hysterectomy as well as the pathological findings in the ovaries. Methods This cross-sectional study was conducted in the department of Pathology at Dow Medical College in Karachi, Pakistan, from September 2017 to December 2018. Data were recorded from the pathology reports of hysterectomy specimens received in the department. Data of hysterectomies performed for gynecological causes in women of reproductive age group were selected and analyzed, using Microsoft Excel (Microsoft, Redmond, Washington) and SPSS version 20 (IBM Corp., Armonk, New York). Data of women more than 49 years and obstetric hysterectomies were excluded.
The wheat plant requires elevated phosphorus levels for its normal growth and yield, but continuously depleting non-renewable phosphorus reserves in the soil is one of the biggest challenges in agricultural production worldwide. The Phosphorus Starvation Tolerance 1 (PSTOL1) gene has been reported to play a key role in efficient P uptake, deeper rooting, and high yield in rice. However, the function of the PSTOL1 gene in wheat is still unclear. In this study, a total of 22 PSTOL1 orthologs were identified in the wheat genome, and found that wheat PSTOL1 orthologs are unevenly distributed on chromosomes, and these genes were under strong purifying selection. Under different phosphorus regimes, wheat PSTOL1 genes showed differential expression patterns in different tissues. These results strengthen the classification of Pakistan-13 as a P-efficient cultivar and Shafaq-06 as a P-inefficient cultivar. Phenotypic characterization demonstrated that Pakistan-13 wheat cultivar has significantly increased P uptake, root length, root volume, and root surface area compared to Shafaq-06. Some wheat PSTOL1 orthologs are co-localized with phosphorus starvation’s related quantitative trait loci (QTLs), suggesting their potential role in phosphorus use efficiency. Altogether, these results highlight the role of the wheat PSTOL1 genes in wheat P uptake, root architecture, and efficient plant growth. This comprehensive study will be helpful for devising sustainable strategies for wheat crop production and adaptation to phosphorus insufficiency.
Diabetes mellitus is one of the commonest chronic diseases, resulting in a lot of complications including a diabetic foot ulcer. Diabetic foot ulcers (DFU) including the risk to progress to amputation, also deteriorate the quality of life of the patients and their care givers. Diabetic foot ulcers not only affect the physical health-related quality of life (HRQoL) of patients but the social, psychological and economic aspects of the patient's life are also affected. Research studies have shown that factors such as female gender, obesity, presence of Peripheral Vascular Disease and stressful life events further decrease the quality of life in patients with diabetic foot ulcers. This editorial advocates that diabetic foot ulcers being a huge burden on the healthcare system also deteriorate the quality of life of patients.
Clinical research bridges patients' unmet medical need with innovative medicines, increases knowledge acquisition by clinicians, and creates solutions to improve the sustainability and quality of the Canadian health care system and economy. The Canadian Institutes of Health Research and the Canadian Lung Association have recently raised concerns over declining research activities within the Canadian respiratory community. While there are currently >3000 ongoing clinical trials in Canada, the number of trials investigating common respiratory diseases is unknown. The objective of the present study was to monitor the trends in industry- and non-industry-sponsored respiratory clinical trials in Canada from 2001 to 2011. Trialtrove 2012 (Citeline, an Informa UK business), a database containing summarized clinical trial information regarding pharmaceutical products, was searched using common chronic respiratory disease terms: "allergic rhinitis", "asthma", "chronic obstructive pulmonary disease (COPD)", "cystic fibrosis", "respiratory infections", "pulmonary fibrosis" and "smoking cessation". Over the past 10 years, the number of respiratory clinical trials conducted in Canada has increased (4.49 per year; P=0.004). From 2001 to 2011, the majority of trials were performed in asthma, followed closely by respiratory infections and COPD. Over the past decade, the number of trials investigating COPD and respiratory infections increased (P<0.05), while asthma trials showed a declining trend since 2007. Of the clinical trials performed during this 10-year period, the majority were in phase III, with a significant increase in the number of phase II trials (2.49 per year; P=0.008). However, certain trends observed are concerning and warrant further monitoring in the coming years.
Introduction Emergency obstetric hysterectomy (EOH) is a life-saving procedure which involves the surgical removal of uterus and is usually performed for uncontrollable maternal hemorrhage when all other conservative management has failed. This study was conducted to evaluate the histopathological findings in the EOH specimen received in the department of pathology. Methods This hospital-based cross-sectional study was conducted in the Histopathology Laboratory, Department of Pathology, and Dow Medical College (DMC) from September 2017 to December 2018. The histopathological findings in the EOH specimen were recorded and data was analyzed. Results Ninety-six cases of EOH were received. The incidence of emergency obstetric hysterectomy was 58.37/10,000 deliveries. The mean age of patients was 30.59 years (range 20-45 years). The main histopathological findings were placenta accreta spectrum in 61 (63.54%) cases, cervical tear in eight (8.33%), uterine rupture in seven (7.29%) and endomyometritis in six (6.25%) cases. In the placenta accreta spectrum, placenta accreta was the most frequent diagnosis in 23 (23.96%) of cases, placenta increta in 17 (17.71%), placenta percreta in 10 (10.42%) cases. Seven (7.29%) cases of placenta percreta and four (4.17%) cases of placenta accreta were diagnosed in association with placenta previa. Twenty placentas were received with the hysterectomies, of these eight (40%) placentas showed infarction and six (30%) had intervillous fibrin, both findings were suggestive of uteroplacental insufficiency, while three (15%) placentas had normal histology. Ovaries were received with the hysterectomies in 11 (11.46%) cases. Mature cystic teratoma was diagnosed in two (2.08%) ovaries while the majority of ovaries were normal on histology. Conclusion Placenta accreta spectrum is the leading histopathological finding in the EOH specimen. Regular antenatal follow-1 2 1 1 3 4 4 4
