Objective: This study examined the current state of forensic education among child and adolescent psychiatry (CAP) fellowship programs, regarding specific forensic topics, teaching resources, methods, and experiences. The authors aimed to gather and analyze this data to assess the need for additional standardization of forensic psychiatry education in CAP fellowship, such as broader access to resources, and/or inform the development of a standardized curriculum, including milestones, in child and adolescent forensic psychiatry.

Methods: The authors collaboratively developed a survey instrument on child and adolescent forensic psychiatry education, which was then sent to 135 accredited CAP fellowship programs.

A novel continuous thin-film (1.59 mm) serpentine path coiled tube (SPCT) UV system operating at 254 nm wavelength was designed and compared with flow field distribution of whole milk with helical path coiled tube (HPCT) UV system using computational fluid dynamics. The results revealed efficient velocity magnitude distribution at serpentine bend geometric locations of the SPCT UV system.

Mental health professionals routinely advise the public to call 911 in case of an acute mental health crisis to access emergent care and ensure safety. Although there is no national database collection process, available data shows that individuals experiencing an acute mental health crisis and Black youth are both at a significantly elevated risk of being harmed or killed by law enforcement during any encounter. This brief analytic essay explores whether advising the public to call 911 is truly the best practice recommendation for Black youth in a mental health crisis.

The onset of the COVID-19 pandemic has presented unique challenges for inpatient psychiatry units (IPUs). IPUs, especially those caring for children and adolescents, rely heavily on milieu group programming to provide care and supervision for patients, and have had to adapt unit policies and procedures to maintain a therapeutic milieu while minimizing COVID-19 transmission. Simultaneously providing care while preventing transmission of COVID-19 within IPUs is a formidable task, and many IPUs face the additional challenge of treating youth who have been exposed to, or are actively infected with, COVID-19.

Anorexia nervosa is among the most lethal of all psychiatric illnesses and is increasingly prevalent in children and adolescents. There are limited treatment options specifically for youth with severe and enduring illness who decline treatment. Although treatment guidelines increasingly favor outpatient family-based treatments, there is a continued role for inpatient psychiatric treatment and involuntary commitment for high-risk patients.

The impact of ultraviolet light (UV-C) irradiation on oxidative enzymes [Polyphenol oxidase (PPO) and Peroxidase (POD)], free essential amino acids and sensory profile of coconut water were investigated. PPO and POD activities were lost to 94 and 93%, respectively of its original value at fluence level of 400 mJ/cm. Inactivation kinetics of both enzymes were fitted to nonlinear Weibull model with an increase in UV dosage with a high coefficient of determination (R > 0.

Soybean ( (L.)) is the world's most important seed legume, which contributes to 25% of global edible oil, and about two-thirds of the world's protein concentrate for livestock feeding. One of the factors that limit soybean's utilization as a major source of protein for humans is its characteristic soy flavor.

The present study presents a novel method employing Near Infrared Spectroscopy (NIR) for detection of the use of calcium carbide in artificial ripening of mangoes. Use of calcium carbide has been banned in artificial ripening of fruits as it contains traces of arsenic. Mango samples were ripened artificially using calcium carbide and compared with naturally ripened mangoes using NIR spectroscopic wavelength ranging from 600 to 1100 nm.

Introduction: Obstructive jaundice as a result of bile duct tumour thrombus (BDTT) is an unusual clinical entity and an uncommon presenting feature of hepatocellular carcinoma (HCC). This study evaluates the outcome of hepatectomy for HCC with obstructive jaundice as a result of BDTT in non-cirrhotic livers.

Methods: Between 1997 and 2012, out of 426 patients with HCC in non-cirrhotic livers, 39 patients with BDTT (Group I n = 39), who underwent a hepatectomy, were analysed and compared with the non-BDTT group (Group II n = 387).

Background: Postoperative infectious complications in patients undergoing pancreatic surgery are a significant cause for morbidity and mortality. Although synbiotics have beneficial effects on human health, their clinical value in surgical patients remains unclear given a paucity of applicable clinical studies.

Aim: To determine the impact of perioperative synbiotic therapy on postoperative infectious complications, morbidity and mortality in patients undergoing pancreatic surgery for chronic pancreatitis.

Halubai, a traditional Indian sweet is conventionally prepared by soaking and grinding whole cereals/millets to a fine paste, straining it through a cloth and cooking the resultant dispersion until it starts gelatinizing. Cooking is continued further with the addition of jaggery water, stirring constantly with intermittent addition of ghee. This process involves many unit operations, which are energy and time consuming.

Background: Prebiotics and probiotics influence all pathogenic mechanisms of bacterial translocation. Used in combination, they are called synbiotics. Postoperative infective complications in patients undergoing hepatic and pancreatic surgery lead to a significant prolongation of hospital stay and increased costs.

Aim: To analyze the differences in outcomes and the clinical impact following pancreatoduodenectomy (PD) in patients with and without aberrant right hepatic artery (aRHA).

Methods: All patients undergoing PD between January 2008 and December 2012 were divided into two groups, one with aRHA and the other without. These groups were compared to identify differences in the intraoperative variables, the oncological clearance and the postoperative morbidity, mortality and hospital stay.

Background: Massive hemobilia is a rare but potentially life-threatening cause of upper gastrointestinal hemorrhage. In this retrospective analysis, we have evaluated the challenges involved in the diagnosis and management of massive hemobilia.

Methods: Between 2001 and 2011, a total of 20 consecutive patients (14 males) who were treated in our department for massive hemobilia were included in the study and their records were retrospectively analyzed.

Gastrointestinal stromal tumors (GISTs) have been recognized as a biologically distinctive tumor type, different from smooth muscle and neural tumors of the gastrointestinal tract (GIT). They constitute the majority of gastrointestinal mesenchymal tumors of the GIT and are known to be refractory to conventional chemotherapy or radiation. They are defined and diagnosed by the expression of a proto-oncogene protein detected by immunohistochemistry which serves as a crucial diagnostic and therapeutic target.

Article Synopsis
  • Curative treatments for hepatocellular carcinoma (HCC) like surgery and liver transplants are only viable for patients with early-stage tumors; later stages need other therapies.
  • Resection is the primary method offering a chance for cure in HCC, but recurrence is common even after surgery.
  • There’s growing interest in transarterial embolization/transarterial chemoembolization (TACE) for various uses in HCC management, showing promise as both a palliative tool and in combination with other therapies.

Unlabelled: Model fruit pulp-based gels were prepared by varying mango pulp (0% to 50%), sucrose (0% to 20%), and agar (1% to 3%) and according to a response surface experimental design followed by drying at a low temperature of 40 °C upto 15 h in a tray dryer assisted by a dehumidifier. The moisture content, shrinkage (SHR), and rheological parameters (failure strain, failure stress (FS), firmness, and energy for compression) were determined as a function of drying time. The composition of gel, particularly the agar content had a prominent effect on the characteristics of the dried gel.
