Evaluation of the efficacy of convalescent plasma in moderate to severe COVID-19 during 2020-2021: a retrospective observational study.

Convalescent plasma therapy (CPT) is one of the treatment modalities used for COVID-19. Initial smaller studies showed the usefulness of CPT in COVID-19, but larger studies showed that it is not effective. This is a retrospective observational study conducted between 1st June 2020 and 31st July 2021 at a tertiary hospital in Noida, India.

Tribally led planetary health education in southeast Alaska.

Limited reporting of Indigenous-led planetary health education programmes has constrained efforts to expand planetary health education, in Indigenous communities and beyond, despite urgent need. Although incorporation of Indigenous knowledge and cultures cannot be standardised, showcasing successful programmes could reveal good practices and aid replicability. In this Personal View, we highlight how shellfish toxin education programmes, designed and organised by the Sitka Tribe of Alaska, reduce local environmental health risks and support youth in pathways towards careers in planetary health.

Adverse Events during Intrahospital Transport of Critically Ill Patients: A Multicenter, Prospective, Observational Study (I-TOUCH Study).

Background: Critically ill patients are frequently transported to various locations within the hospital for diagnostic and therapeutic purposes, which increases the risk of adverse events (AEs). This multicenter prospective observational study was undertaken to determine the incidence of AEs related to intrahospital transport, their severity, and their effects on patient outcomes.

Patients And Methods: We included consecutive unstable critically ill patients requiring intrahospital transport, across 15 Indian tertiary care centers over 5 months (October 11, 2022-February 20, 2023).

Helmet NIV in Acute Hypoxemic Respiratory Failure due to COVID-19: Change in PaO/FiO Ratio a Predictor of Success.

In acute respiratory failure due to severe coronavirus disease 2019 (COVID-19) pneumonia, mechanical ventilation remains challenging and may result in high mortality. The use of noninvasive ventilation (NIV) may delay required invasive ventilation, increase adverse outcomes, and have a potential aerosol risk to caregivers. Data of 30 patients were collected from patient files and analyzed.

Intensive Care in India in 2018-2019: The Second Indian Intensive Care Case Mix and Practice Patterns Study.

Background: We aimed to study organizational aspects, case mix, and practices in Indian intensive care units (ICUs) from 2018 to 2019, following the Indian Intensive Care Case Mix and Practice Patterns Study (INDICAPS) of 2010-2011.

Methods: An observational, 4-day point prevalence study was performed between 2018 and 2019. ICU, patient characteristics, and interventions were recorded for 24 hours, and ICU outcomes till 30 days after the study day.

High-flow Tracheal Oxygenation: A New Tool for Difficult Weaning.

Unlabelled: High-flow tracheal oxygenation (HFTO), a modification of high-flow nasal cannula (HFNC), has been used in tracheostomized patients but only rarely for weaning. We present two cases on prolonged mechanical ventilation (PMV) where HFTO assisted weaning.

Noninvasive Ventilation-assisted Bronchoscopy in High-risk Hypoxemic Patients.

Background And Aims: Hypoxemic patients undergoing fiber-optic bronchoscopy (FOB) are at risk of worsening of respiratory failure requiring mechanical ventilation due to FOB procedure itself and its complications. As patients with respiratory failure are frequently managed by non-invasive ventilation (NIV); feasibility of FOB through NIV mask has been evaluated in some studies to avoid intubation. We describe here our own case series.

Complement 7 Is Up-Regulated in Human Early Diabetic Kidney Disease.

There is a temporal window from the time diabetes is diagnosed to the appearance of overt kidney disease during which time the disease progresses quietly without detection. Currently, there is no way to detect early diabetic nephropathy (EDN). Herein, we performed an unbiased assessment of gene-expression analysis of postmortem human kidneys to identify candidate genes that may contribute to EDN.

Improving Transitions to Postacute Care for Elderly Patients Using a Novel Video-Conferencing Program: ECHO-Care Transitions.

Purpose: Within 30 days of hospital discharge to a skilled nursing facility, older adults are at high risk for death, re-hospitalization, and high-cost health care. The purpose of this study was to examine whether a novel videoconference program called Extension for Community Health Outcomes-Care Transitions (ECHO-CT) that connects an interdisciplinary hospital-based team with clinicians at skilled nursing facilities reduces patient mortality, hospital readmission, skilled nursing facility length of stay, and 30-day health care costs.

Methods: We undertook a prospective cohort study comparing cost and health care utilization outcomes between ECHO-CT facilities and matched comparisons from January 2014-December 2014.

Extension for Community Healthcare Outcomes-Care Transitions: Enhancing Geriatric Care Transitions Through a Multidisciplinary Videoconference.

Objectives: To examine whether a novel videoconference that connects an interdisciplinary hospital-based team with clinicians at postacute care sites improves interprofessional communication and reduces medication errors.

Design: Prospective cohort.

Setting: One tertiary care medical center and eight postacute care sites.

Voriconazole-Induced Periostitis & Enthesopathy in Solid Organ Transplant Patients: Case Reports.

Background: Voriconazole is frequently used to treat fungal infections in solid organ transplant patients. Recently, there have been reports suggesting that prolonged voriconazole therapy may lead to periostitis.

Aim: Here we present two cases of voriconazole-induced periostitis in solid organ transplant patients.

Impact of bronchoalveolar lavage multiplex polymerase chain reaction on microbiological yield and therapeutic decisions in severe pneumonia in intensive care unit.

Purpose: The purpose of the study is to evaluate the impact of adding bronchoalveolar lavage multiplex polymerase chain reaction (M-PCR) to conventional cultures (CC) on microbiological yield and therapeutic decisions in adult intensive care unit patients with pneumonia and severe sepsis or septic shock.

Material And Methods: In this retrospective case-control study, bronchoalveolar lavage cultures were taken for control (58 patients, 58 admissions) and study arms (57 patients, 58 admissions). Bronchoalveolar lavage M-PCR was sent simultaneously for the latter.

Pathogenesis of preeclampsia.

Purpose Of Review: Preeclampsia is a gestational kidney disease characterized by glomerular endothelial injury, leading to maternal hypertension and proteinuria. If not addressed promptly, there is significant maternal and fetal morbidity and mortality. When severe, this disorder can cause hepatic and neurologic dysfunction.

The tick salivary protein sialostatin L2 inhibits caspase-1-mediated inflammation during Anaplasma phagocytophilum infection.

Saliva from arthropod vectors facilitates blood feeding by altering host inflammation. Whether arthropod saliva counters inflammasome signaling, a protein scaffold that regulates the activity of caspase-1 and cleavage of interleukin-1β (IL-1β) and IL-18 into mature molecules, remains elusive. In this study, we provide evidence that a tick salivary protein, sialostatin L2, inhibits inflammasome formation during pathogen infection.

The impact of low serum sodium on treatment outcome of targeted therapy in metastatic renal cell carcinoma: results from the International Metastatic Renal Cell Cancer Database Consortium.

Background: Hyponatremia has been associated with poor survival in many solid tumors and more recently found to be of prognostic and predictive value in metastatic renal cell cancer (mRCC) patients treated with immunotherapy.

Objective: To investigate the influence of baseline hyponatremia in mRCC patients treated with targeted therapy in the International Metastatic Renal Cell Carcinoma Database Consortium.

Design, Setting, And Participants: Data on 1661 patients treated with first-line vascular endothelial growth factor (VEGF) or mammalian target of rapamycin (mTOR) targeted therapy for mRCC were available from 18 cancer centers to study the impact of hyponatremia (serum sodium level <135 mmol/l) on clinical outcomes.

Oncogenic PI3K mutations lead to NF-κB-dependent cytokine expression following growth factor deprivation.

The phosphoinositide 3-kinase (PI3K) pathway is one of the most commonly misregulated signaling pathways in human cancers, but its impact on the tumor microenvironment has not been considered as deeply as its autonomous impact on tumor cells. In this study, we show that NF-κB is activated by the two most common PI3K mutations, PIK3CA E545K and H1047R. We found that markers of NF-κB are most strongly upregulated under conditions of growth factor deprivation.

Trafficking and proteolytic processing of RNF13, a model PA-TM-RING family endosomal membrane ubiquitin ligase.

RING finger protein 13 (RNF13) is a ubiquitously expressed, highly regulated ubiquitin ligase anchored in endosome membranes. A RING domain located in the cytoplasmic half of this type 1 membrane protein mediates ubiquitination in vitro but physiological substrates have not yet been identified. The protein localized in endosomal membranes undergoes extensive proteolysis in a proteasome-dependent manner, but the mRNA level can be increased and the encoded protein stabilized under specific physiological conditions.

Calcium channel blocker overdose: experience with amlodipine.

Amlodipine overdose is only scarcely reported from India. We report two cases of near fatal Amlodipine overdose managed in our ICU with fluid, vasopressors, calcium infusion and Glucagon. Literature is reviewed and other treatment modalities discussed.

Neutrophil transmigration under shear flow conditions in vitro is junctional adhesion molecule-C independent.

Endothelial cell junctional adhesion molecule (JAM)-C has been proposed to regulate neutrophil migration. In the current study, we used function-blocking mAbs against human JAM-C to determine its role in human leukocyte adhesion and transendothelial cell migration under flow conditions. JAM-C surface expression in HUVEC was uniformly low, and treatment with inflammatory cytokines TNF-alpha, IL-1beta, or LPS did not increase its surface expression as assessed by FACS analysis.
