Background And Aims: Acute pancreatitis (AP) frequently presents in emergency departments and poses challenges in predicting severity and mortality. Established scoring systems like Ranson criteria, Acute Physiology And Chronic Health Evaluation II (APACHE) II, and Bedside Index of Severity in Acute Pancreatitis (BISAP) have varying effectiveness. Lactate dehydrogenase (LDH), an enzyme released during tissue damage, shows promise as a marker for organ injury in AP.

forms a gel-like biofilm in the Foley's catheter (FC) causing tenacious biofouling and severe urinary tract infections (UTIs). For the first time, a spice extract-based antifungal lock therapy (ALT) has been developed to inhibit the gel matrix in FC. Aqueous extracts of garlic, clove, and Indian gooseberry were used as ALT lock solutions and tested against biofilm-forming multidrug-resistant clinical isolates of .

  • Estimates indicate significant variation in R&D costs, with 20 large firms comprising 80.8% of patient-months and showing lower costs per patient-month compared to smaller firms.
  • A novel methodology was used to analyze R&D costs per drug, focusing on discrete units of activity related to clinical trials and using data from 268 US publicly traded drug developers.
  • The study found that R&D costs per new drug averaged around $1.31 billion, with a lower median cost of $708 million, highlighting a skewed distribution of expenses related to drug development.

Introduction: Immunogenicity continues to be a challenge for development and clinical utility of monoclonal antibodies, and there are gaps in our current ability to prevent anti-drug antibody development in a safe and antigen-specific manner.

Methods: To mitigate immunogenicity of monoclonal antibodies administered subcutaneously, O-phospho-L-serine (OPLS)-the head group of the tolerance-inducing phospholipid, phosphatidylserine-was investigated as an immunoregulatory adjuvant.

Results: Formulations of adalimumab, trastuzumab or rituximab with OPLS showed reduction in relative immunogenicity in mice compared to vehicle formulations, indicated by reduced anti-drug antibody development and significant reductions in CD138+ plasma cell differentiation in bone marrow.

Background: This study evaluates the fracture resistance of apical plugs created from Biodentine and mineral trioxide aggregate (MTA) in thicknesses of 3 and 5 mm within simulated open apex tooth models.

Methods: Fifty human maxillary central incisors were obtained from a pool of freshly extracted teeth. In order to replicate open apices without cavity preparation, ten teeth in the control group received apical-to-coronal preparation with Peeso reamers.

Background: Pulp capping is a vital dental procedure used to preserve the vitality of teeth affected by deep caries lesions without irreversible pulpitis. The use of modern bioceramic materials has enhanced the predictability of vital pulp therapy (VPT).

Aim: This study aimed to assess the clinical success of Biodentine, modified NeoPutty mineral trioxide aggregate (MTA), and calcium hydroxide (Ca(OH)2) as pulp capping materials for indirect pulp capping in carious primary teeth.

  • The WHO declared COVID-19 a public health emergency in January 2020 and a pandemic in March 2020, prompting NIMHANS to launch a national helpline to address mental health issues during this crisis.
  • An analysis of 70 helpline callers revealed that 71.1% were aged 60-70, 38.6% had preexisting mental illnesses (mainly anxiety and sleeplessness), and many faced additional medical issues.
  • The study found that telephonic interventions, including supportive psychotherapy and information about COVID-19, were effective in addressing the mental health concerns of the elderly during the pandemic.

The occurrence of morphological deviations in root canal anatomy is challenging and can influence treatment outcomes. While mandibular second molars typically have 2 roots and 3 canals, a unique case emerged in a 23-year-old Indian male with a symptomatic permanent left mandibular second molar showing three distal, two mesial canals, and two roots. The tooth presented as non-mobile but tender on percussion.

Objective: A feared complication of aminoglycoside treatment is ototoxicity, which is theorized to be attributed to the production of aminoglycoside-induced reactive oxygen species. Previous studies using animal models have suggested that numerous therapies targeting reducing oxidative stress may prevent ototoxicity from aminoglycosides. However, few clinical studies have been conducted on these antioxidants.

Article Synopsis
  • - Sarcopenia, a condition involving muscle loss, is common in men with liver cirrhosis and has negative effects on health, including increasing the risk of hepatic encephalopathy (HE); androgen receptor agonists (ARAs) like LPCN 1148 show potential to address these issues but their effectiveness and safety in this demographic were previously unclear.
  • - In a phase 2 trial, men with cirrhosis and sarcopenia were given either LPCN 1148 or placebo for 24 weeks, with results indicating that those taking LPCN 1148 had a significant increase in muscle mass (measured by CT scans) and experienced fewer episodes of serious HE compared to the placebo group.

  • - RLYB212 is a human monoclonal antibody in clinical trials aimed at preventing maternal alloimmunization to fetal platelet antigen HPA-1a, which can cause fetal and neonatal alloimmune thrombocytopenia (FNAIT).
  • - A target-mediated drug disposition (TMDD) model was developed to analyze how RLYB212 interacts with both the drug's pharmacokinetics (PK) and the dynamics of HPA-1a-positive platelets in HPA-1b/b volunteers.
  • - Simulations using the TMDD model identified a dosing regimen of 0.06 mg RLYB212 with a loading dose of 0.12 mg as optimal, ensuring drug levels remain below
