Association of Posterior Reversible Encephalopathy Syndrome (PRES) with Preeclampsia with Severe Symptoms and Eclampsia in South East Part of Bangladesh.

Posterior reversible encephalopathy syndrome (PRES) is a pathology seen not only in precelampsia with severe symptoms and eclampsia but in a varicty of diseases/ conditions. With the availability of neuroimaging, it is possible to know the exact underlying Central nervous system (CNS) pathology in preeclampsia with severe symptoms and eclampsia and thus therapy can be targeted. Preeclampsia with severe symptoms and eclampsia remains to be an important cause of maternal morbidity and mortality in both the developing and developed world. The objective of this study was to evaluate the association of Posterior reversible encephalopathy syndrome (PRES) by MRI (Magnetic resonance imaging) with preeclampsia with severe symptoms and eclampsia in south east part of Bangladesh. This cross-sectional observational study was performed among women suffering from preeclampsia with severe symptoms and eclampsia who attended at Obstetrics & Gynaecology department of Chittagong Medical College Hospital (CMCH), Bangladesh from January 2021 to June 2021. According to inclusion/exclusion criteria 50 samples were taken by convenient sampling for this study. A detail history was taken and complete general physical and gynecological examination was performed. Required data was collected through preset questionnaire. Neuroimaging reports were reviewed by both neurologist and radiologist. Data was analyzed by using windows based computer software device, SPSS 25.0. Results obtained from this study will be used to make a statement regarding aggressive management for cerebral vasospasm in severe preeclampsia and eclamptia related PRES. PRES has been reported to be reversible but late recognition or incorrect treatment can cause irreversible brain damage. Institution of early treatment leads to resolution of symptoms without any neurologic deficit and thus reduces maternal morbidity and mortality. PRES is a cliniconeuroradiologic entity. This study can aware doctors regarding prompt diagnosis of PRES in peripartum period among patient suffering from preeclampsia with severe symptoms and eclampsia by imaging aside clinical findings. A conclusive decision can be made to improve the outcome in this potentially life threatening but reversible condition.

Gut dysbiosis, inflammation and type 2 diabetes in mice using synthetic gut microbiota from diabetic humans / Disbiose intestinal, inflamação e diabetes tipo 2 em camundongos usando microbiota intestinal sintética de humanos diabéticos

The study was aimed to assess impact of high fat diet (HFD) and synthetic human gut microbiota (GM) combined with HFD and chow diet (CD) in inducing type-2 diabetes (T2D) using mice model. To our knowledge, this is the first study using selected human GM transplantation via culture based method coupled dietary modulation in mice for in vivo establishment of inflammation leading to T2D and gut dysbiosis. Twenty bacteria (T2D1-T2D20) from stool samples of confirmed T2D subjects were found to be morphologically different and subjected to purification on different media both aerobically and anerobically, which revealed seven bacteria more common among 20 isolates on the basis of biochemical characterization. On the basis of 16S rRNA gene sequencing, these seven isolates were identified as Bacteroides stercoris (MT152636), Lactobacillus acidophilus (MT152637), Lactobacillus salivarius (MT152638), Ruminococcus bromii (MT152639), Klebsiella aerogenes (MT152640), Bacteroides fragilis (MT152909), Clostridium botulinum (MT152910). The seven isolates were subsequently used as synthetic gut microbiome (GM) for their role in inducing T2D in mice. Inbred strains of albino mice were divided into four groups and were fed with CD, HFD, GM+HFD and GM+CD. Mice receiving HFD and GM+modified diet (CD/HFD) showed highly significant (P<0.05) increase in weight and blood glucose concentration as well as elevated level of inflammatory cytokines (TNF-α, IL-6, and MCP-1) compared to mice receiving CD only. The 16S rRNA gene sequencing of 11 fecal bacteria obtained from three randomly selected animals from each group revealed gut dysbiosis in animals receiving GM. Bacterial strains including Bacteroides gallinarum (MT152630), Ruminococcus bromii (MT152631), Lactobacillus acidophilus (MT152632), Parabacteroides gordonii (MT152633), Prevotella copri (MT152634) and Lactobacillus gasseri (MT152635) were isolated from mice [...].

Camundongos que receberam a dieta modificada com HFD e GM + (CD / HFD) mostraram um aumento altamente significativo (P < 0,05) no peso e na concentração de glicose no sangue, bem como um nível elevado de citocinas inflamatórias (TNF-α, IL-6 e MCP-1) em comparação com os ratos que receberam apenas CD. O sequenciamento do gene 16S rRNA de 11 bactérias fecais obtidas de três animais selecionados aleatoriamente de cada grupo revelou disbiose intestinal em animais que receberam GM.

Deprescribing proton pump inhibitors: evidence-based clinical practice guideline

OBJECTIVE: To develop an evidence-based guideline to help clinicians make decisions about when and how to safely taper or stop proton pump inhibitors (PPIs); to focus on the highest level of evidence available and seek input from primary care professionals in the guideline development, review, and endorsement processes. METHODS: Five health professionals (1 family physician, 3 pharmacists, and 1 gastroenterologist) and 5 nonvoting members comprised the overall team; members disclosed conflicts of interest. The guideline process included the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach, with a detailed evidence review in in-person, telephone, and online meetings. Uniquely, the guideline development process included a systematic review of PPI deprescribing trials and examination of reviews of the harm of continued PPI use. Narrative syntheses of patient preferences and resource-implication literature informed recommendations. The team refined guideline content and recommendation wording through consensus and synthesized clinical considerations to address common front-line clinician questions. The draft guideline was distributed to clinicians and then to health care professional associations for review and revisions made at each stage. A decision-support algorithm was developed in conjunction with the guideline. RECOMMENDATIONS: This guideline recommends deprescribing PPIs (reducing dose, stopping, or using "on-demand" dosing) in adults who have completed a minimum of 4 weeks of PPI treatment for heartburn or mild to moderate gastroesophageal reflux disease or esophagitis, and whose symptoms are resolved. The recommendations do not apply to those who have or have had Barrett esophagus, severe esophagitis grade C or D, or documented history of bleeding gastrointestinal ulcers. CONCLUSION: This guideline provides practical recommendations for making decisions about when and how to reduce the dose of or stop PPIs. Recommendations are meant to assist with, not dictate, decision making in conjunction with patients.
