An overview of the latest outlook of sulfamate derivatives as anticancer candidates (2020-2024).

Considering the emergence of new anticancer drugs, in this review we emphasized and highlighted the recent reports and advances related to sulfamate-incorporating compounds with potential anticancer activity during the last 5 years (2020-2024). Additionally, we discussed their structure-activity relationship, clarifying their potent bioactivity as anticancer agents. Sulfamate derivatives hold promise as effective therapeutic candidates against cancer. By targeting biological targets associated with the development of cancer, such as steroid sulfatases (STS), carbonic anhydrases (CAs), microtubules, NEDD8-activating enzyme, small ubiquitin-like modifiers (SUMO)-activating enzyme (SAE), cyclin-dependent kinases (CDKs), breast cancer susceptibility gene 1 (BRCA1), and so on, this can furnish small molecules as anticancer lead candidates serving the drug discovery field. For example, compound 2, an STS inhibitor, demonstrated superior activity compared to its reference, irosustat, by fivefold. In addition, compound 21, an SAE, is under phase I clinical trials. Continued research into sulfamate derivatives holds potential for the development of novel therapeutic agents targeting various diseases.

Molecular subtyping and phylogeny of Blastocystis sp. isolated from turkey (Meleagris gallopavo) populations in Penang, Malaysi.

Most poultry farms in Malaysia preferred rearing chickens either for eggs or/and meat than turkeys. This is due to several challenges such as parasitic load and heat stress in rearing turkey. Blastocystis is one of the most common protozoan parasites infecting poultry. As no study was conducted on Blastocystis infection in turkey in Malaysia, this study aims to determine the current status, the morphological characteristics and subtyping of Blastocystis from turkey reared either in closed house or free-range system in Penang, Malaysia. It was found that the prevalence of Blastocystis sp. infection in turkeys were moderately high with 41.6% (25/60) in the closed house and 45.0% (45/100) in free-range system as infection was higher in the female turkeys with no gastrointestinal signs and symptoms. Vacuolar form was the most common form found in the in vitro culture ranged between 5 to 20 µm in diameter with a rough surface coat and undulating cell surface viewed under the scanning electron microscope. Meanwhile, the ultrastructure of the cells from turkey isolates were varies with partially expanded electron-opaque vacuoles to electron-dense in fully distended vacuoles. Interestingly, sequence analysis for 30 positive Blastocystis isolates from turkeys revealed one subtypes with three alleles namely, ST7 allele 99 (73.4%, n=22), ST7 allele 100 (23.3%, n=7) and ST7 allele 101 (3.3%, n=1). Findings from this study added to our understanding on Blastocystis infection in turkey production.

Prevalence of depression among hypothyroid patients attending the primary healthcare and endocrine clinics of King Fahad Hospital of the University (KFHU).

CONTEXT: Hypothyroidism is the most prevalent endocrine disorder worldwide, with a prevalence of 4%-5%. Thyroid hormone has a role in neurological development, and hormone deficiency can be manifested by many neurological signs and symptoms such as behavioral disturbances, anxiety, and depressive symptoms. AIMS: To estimate the prevalence of depression among hypothyroid patients attending primary healthcare and endocrine clinic of King Fahad Hospital of the University (KFHU) and to assess the relationship between depression and different factors. SETTINGS AND DESIGN: A cross-sectional study was conducted to estimate the prevalence of depression among hypothyroid patients attending the primary healthcare and endocrine clinics of KFHU in Al Khobar. MATERIALS AND METHODS: Patients were screened for depression using Patient Health Questionnaire-9 screening tool, in addition to obtaining their sociodemographic data, details of their thyroid function status, and other risk factors for depression. Also, patient medical files were used to obtain the laboratory results. STATISTICAL ANALYSIS USED: Data were analyzed using the Statistical Package for the Social Science (SPSS) version 23. Continuous data were displayed using mean and standard deviation; categorical data were displayed in numbers and percentage. Chi-square test was used to assess the relationship between the variables. A P value of less than 0.05 was considered as statistically significant. RESULTS: It was found that 33.9% of patients were depressed with varying degree of depression. Certain symptoms were found to be associated with higher risk of depression such as fatigue, memory problems, hair loss, and gland enlargement. CONCLUSION: Depression was concluded to be prevalent among hypothyroid patients. And screening for depression among hypothyroid patients is recommended.

Common errors in writing the cause of death certificate in the Middle East.

A death certificate is an official document in which the medical practitioner primarily records the cause of death sequence, the time interval between the onset of the cause of death and death, and personal details of the deceased. Errors in death certificate documentation are not uncommon. We aim to review the common errors in writing the cause of death certificate in the Middle East. For this review, we searched the PubMed database using a comprehensive search strategy to identify studies from the Middle East that reported errors in the cause of death certification from inception to August 17, 2019. Of the 308 items initially identified, 5 were eligible for inclusion. These studies were reported from only a few countries (Saudi Arabia, Iran, Lebanon and Palestine) in the Middle East and did not represent all the countries geographically located in the Middle East. The Middle East is not immune to errors in the medical certification of the cause of death. The absence of the cause of death, inappropriate listing and sequencing of the causes of death, mentioning the mechanism or mode of death instead of the cause of death, absence of time interval between the onset of the cause of death and death, use of abbreviations and symbols instead of formal medical terminology, and absence of the certifying medical practitioner's signature were the commonly death certification errors observed in this regional literature review. Additional studies to assess death certification errors in all the Middle East countries are needed. Efforts should be made to compulsorily include the teaching and learning of the cause of death certification in the undergraduate medical curriculum. Interactive workshops on drafting the cause of death certificate should be periodically conducted for the benefit of the interns and residents.

Reflex Seizures Triggered by Diaper Change in Dravet Syndrome.

Dravet syndrome (DS) is a severe epilepsy syndrome characterized by early onset of multiple types of seizures. We report the first case of reflex seizures triggered by diaper change in a girl at 9 months old and 2 years old with a mutation in the SCN1A gene causing DS. Reflex seizures have been reported in patients with DS provoked by increased body temperature or visual stimulation. The case we report widens the spectrum of triggers causing reflex seizures in children with DS. Cortical hyperexcitability resulting from the genetic defect explains the tendency to experience such reflex seizures.

Retrospective Review of the Adjunctive Use of Pre- Operative Ranibizumab “LUCENTISTM” in the Surgical Management of Diabetic Retinopathy in a Tertiary Referral Hospital in Malaysia

A retrospective case series review was conducted to determine the pre-operative role and safety of pre-operative adjunctive anti-vascular endothelial growth factor (anti- VEGF) agent ranibizumab “LUCENTISTM” in patients with diabetic retinopathy requiring vitrectomy. The study involved twenty consecutive eyes of sixteen patients (age range: 46-72 years; mean 57.5 years) which received intravitreal injection of 0.5 - 1 mg of ranibizumab 3 to 8 days (mean 4.4 days) prior to vitrectomy for diabetic retinopathy. There were no local or systemic post-injection complications. Indications for vitrectomy were retinal detachment (RD) [n=11; 3 combined tractional (TRD) - rhegmatogenous RD (RRD), 8 TRD], TRD with vitreous haemorrhage (VH) (n=3) ,VH (n=8) and vitreomacular traction syndrome (n=1). Inclusion criteria include all consecutive eyes of diabetic patients requiring vitrectomy receiving a first pre-operative injection of anti- VEGF. Pre-operative visual acuity (VA) ranged from 6/36 to light perception. All eyes had minimal to moderate intraoperative bleeding. Post-operative VH in eyes without tamponade or gas tamponade was nil (n=1), mild (n=13) or moderate (n=1). Silicone filled eyes had nil (n=1), moderate (n=3) or severe haemorrhages (n=1). Post-operative VA was unchanged (n=2) (10%), improved (n = 14) (70%) or worsened (n=4). VA was 2/60 or better (n=15) to no light perception (n=1). Two eyes achieved 6/12 or better vision (10%). Ten eyes (50%) had 6/36 or better vision. In conclusion, pre-operative intravitreal ranibizumab is safe and useful in diabetic vitrectomy and appears to help with perioperative bleeding leading to improvement in vision.
