Entamoeba histolytica (E. histolytica) is a protozoan parasite that causes amoebiasis in humans. It is prevalent in developing countries, particularly in areas with inadequate sanitation and limited access to clean water. While some data on the infection in the Malaysian population is available, comprehensive data on the overall prevalence is lacking. Our study aimed to determine the prevalence of E. histolytica in Malaysia through systematic review and meta-analysis using data published up to 2025. Fourteen studies covering diverse population groups from various states in Malaysia, including rural and urban residents, schoolchildren, indigenous communities, and high-risk populations were reviewed. We found an overall pooled prevalence of 7% with high heterogeneity (I² = 92.5%). Prevalence varied widely by state and population subgroup, with higher rates in Pahang (18%) and among aboriginal schoolchildren (16%). Lower prevalence was found among urban residents (2%) and patients with gastrointestinal disorders (2%). There was only a slight difference in prevalence between individuals with co-infections (8%) and those without (7%). Studies using microscopy showed higher prevalence (7%) than molecular methods (4%). This is likely due to the misidentification of non-pathogenic Entamoeba species as E. histolytica when using microscopy. These findings contribute to a better understanding of the epidemiology of E. histolytica intestinal infection in Malaysia. Although the overall prevalence is relatively low, the results highlight the need for continued surveillance and more accurate diagnostic approaches to support targeted control.

Purpose: Immunosuppressive therapy is frequently administered to patients with inflammatory bowel disease (IBD), which may make them more susceptible to infections like hepatitis B. Methods: A cross-sectional study was conducted on patients aged 5–18 years diagnosed with IBD who visited a gastroenterology clinic along with controls who were the same age as the patients with IBD and were healthy overall. A logistic regression analysis using the independent variables of age, sex, race, disease phenotype, surgery, and medications and the dependent variable of adequate hepatitis B surface antibody (HBsAb) titers (>10 mIU/mL) was performed on quantitative serum HBsAb titers. Results: The study enrolled 62 patients, including 37 males and 25 females. Crohn’s disease, ulcerative colitis, and indeterminate colitis were diagnosed in 16, 22, and 24 patients, respectively. Thirty-nine patients were taking corticosteroids at the time of the study, 42 were taking immunomodulators, and four were taking biologics. Compared to 44.7% of the control group, 9.3% of the patients had protective titers. Only 12 out of 62 patients had HBsAb titers greater than 10 million IU/mL. None of the patients who received biologics or corticosteroids and 3.2% of those who received immunomodulators were found to be seroimmuned. Conclusion The younger patients had the highest titers. Patient-specific factors that may impact these low titers include the length of the patient’s illness and the use of immunosuppressants.

In the last quarter of a century, the backdrop of appropriate ambulatory and office-based surgeries has changed dramatically. Procedures that were traditionally done in hospitals or patients being admitted after surgery are migrating to the outpatient setting and being discharged on the same day, respectively, at a remarkable rate. In the face of this exponential growth, anesthesiologists are constantly being challenged to maintain patient safety by understanding the appropriate patient selection, procedure, and surgical location. Recently published literature supports the trend of higher, more medically complex patients, and more complicated procedures shifting towards the outpatient arena. Several reasons that may account for this include cost incentives, advancement in anesthesia techniques, enhanced recovery after surgery (ERAS) protocols, and increased patient satisfaction. Anesthesiologists must understand that there is a lack of standardized state regulations regarding ambulatory surgery centers (ASCs) and office-based surgery (OBS) centers. Current and recently graduated anesthesiologists should be aware of the safety concerns related to the various non-hospital-based locations, the sustained growth and demand for anesthesia in the office, and the expansion of mobile anesthesia practices in the US in order to keep up and practice safely with the professional trends. Continuing procedural ambulatory shifts will require ongoing outcomes research, likely prospective in nature, on these novel outpatient procedures, in order to develop risk stratification and prediction models for the selection of the proper patient, procedure, and surgery location.

There has been an exponential increase in plastic surgery cases over the last 20 years, surging from 2.8 million to 17.5 million cases per year. Seventy-two percent of these cases are being performed in the office-based or ambulatory setting. There are certain advantages to performing aesthetic procedures in the office, but several widely publicized fatalities and malpractice claims has put the spotlight on patient safety and the lack of uniform regulation of office-based practices. While 33 states currently have legislation for office-based surgery and anesthesia, 17 states have no mandate to report patient deaths or adverse outcomes. The literature on office-base surgery and anesthesia has demonstrated significant improvements in patient safety over the last 20 years. In the following review of the proceedings from the PRS Korea 2018 meeting, we discuss several key concepts regarding safe anesthesia for officebased cosmetic surgery. These include the safe delivery of oxygen, appropriate local anesthetic usage and the avoidance of local anesthetic toxicity, the implementation of Enhanced Recovery after Surgery protocols, multimodal analgesic techniques with less reliance on narcotic pain medications, the use of surgical safety checklists, and incorporating “the patient” into the surgical decision-making process through decision aids.

Disseminated microsporidiosis among HIV/AIDS patients is life-threatening. The incidence may be actually higher than what has been reported. This is due to non-specific presentations of the disseminated cases and also the insensitivity of routine diagnostic technique which contribute to delay in the treatment of the disease. In the present study, we report the use of blood specimens to detect circulating microsporidia DNA, which has not been reported for diagnosis of disseminated microsporidiosis. Blood samples from HIV/AIDSpositive patients were collected over a period of one year. These samples were subjected to PCR assay using species-specific primer EBIEF1/EBIER1. Out of 100 patients, seven were confirmed positive for E. bieneusi by PCR. A fragment of 607 bp was successfully amplified. Identification of circulating microsporidia DNA in blood samples may aid in early diagnosis, thereby allows timely administration of anti-parasitic treatment.

Acanthogyrus (Acanthosentis) tilapiae parasites were collected from the intestines of 300 fish belonging to three tilapia species sourced at the River Nile, Giza, Egypt. The proboscis of the parasite was characterized by three rows of hooks that curved towards the posterior of the body. The first row is supported by unmodified hooks. The parasite tegument has a series of alternative folds and a large number of pores. Sensory ganglia are located on the surface of the proboscis and body. Acanthogyrus (Acanthosentis) tilapiae provokes an aggressive host response indicated by hyperplasia of the intestinal goblet cells and focal eosinophil infiltrations. This acanthocephalan parasite shows a highly modified adaptation to its site of host infection.
