1007/s13205-021-02695-x.The development of genome-editing technologies in 1970s has discerned a new beginning in the field of science. Out of different genome-editing approaches such as Zing-finger nucleases, TALENs, and meganucleases, clustered regularly interspaced short palindromic repeats-CRISPR-associated protein 9 (CRISPR/Cas9) is a recent and versatile technology that has the ability of making changes to the genome of different organisms with high specificity. Cancer is a complex process that is characterized by multiple genetic and epigenetic changes resulting in abnormal cell growth and proliferation. As cancer is one of the leading causes of deaths worldwide, a large number of studies are done to understand the molecular mechanisms underlying the development of cancer. Because of its high efficiency and specificity, CRISPR/Cas9 has emerged as a novel and powerful tool in the field of cancer research. CRISPR/Cas9 has the potential to accelerate cancer research by dissecting tumorigenesis process, generating animal and cellular models, and identify drug targets for chemotherapeutic approaches. However, despite having tremendous potential, there are certain challenges associated with CRISPR/Cas9 such as safe delivery to the target, potential off-target effects and its efficacy which needs to be addressed prior to its clinical application. In this review, we give a gist of different genome-editing technologies with a special focus on CRISPR/Cas9 development, its mechanism of action and its applications, especially in different type of cancers. We also highlight the importance of CRISPR/Cas9 in generating animal models of different cancers. Finally, we present an overview of the clinical trials and discuss the challenges associated with translating CRISPR/Cas9 in clinical use.In this study, the submerged culture conditions for exopolysaccharide (EPS) production by Ganoderma cantharelloideum M. H. Liu were screened and optimized, and the physicochemical and biological properties of EPS were investigated. Results showed that the glucose and tryptone were the best C and N sources for the maximum EPS production, respectively. Under the optimal culture conditions, the EPS production achieved 1.60 g/L at day 6 in a 5 L stirred tank reactor. Two purified fractions (i.e., Fr-I and Fr-II) were obtained from the G. cantharelloideum EPS by gel permeation chromatography. Fr-II had a higher yield (87.54%), carbohydrate (95.86%), and protein (3.07%) contents and lower molecular weight (74.56 kDa) than that of Fr-I. Both Fr-I and Fr-II were polysaccharide-protein complexes with different monosaccharide compositions and chemical structures. Fr-II also exhibited stronger radical scavenging abilities, antioxidant capacities, and α-amylase and α-glycosidase inhibitory activities in vitro than that of Fr-I. Therefore, Fr-II obtained from G. cantharelloideum EPS might be explored as potential natural functional components or supplements for applications in food, medicine, and cosmetics.The novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), is responsible for an array of extrapulmonary manifestations, including direct and indirect neurological complications. Currently, all published cases noting pituitary apoplexy in patients with COVID-19 have discovered underlying pituitary macroadenomas. Herein, we describe the first documented case, to our knowledge, of pituitary apoplexy attributed solely to COVID-19 in the absence of other identifiable causes. While much remains to be discovered and understood regarding COVID-19, we discuss the potential pathophysiology of COVID-19-associated pituitary apoplexy and raise awareness of this clinical complication.Background Childhood poisoning is a major health problem. Mostly, it is accidental and associated with low morbidity and mortality. The association between sociodemographic factors and childhood injury rates could be used for improvement to prevent and reduce such injuries. Childhood poisoning is preventable through appropriate education and judicious storage of drugs and household chemicals that might help in reducing and eliminating the accidental ingestion of toxic materials at home. Objectives To recognize the potential risk factors that might be associated with childhood home poisoning in Riyadh City, Kingdom of Saudi Arabia. Design A survey-based questionnaire study. Setting A tertiary care teaching hospital in Riyadh City. Patients and methods A structured questionnaire was created, which included questions on the poisoning incidence, home medication history, and possible risk factors for poisoning and the sociodemographic characteristics, and was disseminated to individuals who visited the King Khalid significant cause of morbidity and possible mortality. Creating health education and prevention programs might help to prevent such serious preventable problems. Limitations The limited number of participants may not reflect the whole population living in Riyadh City, hence, interpretation of the study results might be taken cautiously. Conflict of interest There was no conflict of interest.Background Functional disability in older adults is common and adversely impacts the quality of life. Given the paucity of population-based data, the present analysis attempted to determine the prevalence and factors associated with functional disability in basic activities of daily living (ADLs) among the elderly population in a rural setting of Northeastern state of India Methods A total of 430 elderly were recruited in a population-based cross-sectional study among elderly individuals (≥60 years) during the period 2013-2016 in rural areas of the Dibrugarh district of Northeastern India. The Barthel index was used to measure ADL. Anyone with a Barthel index score less then 100 (or having limitations in one or more ADL items) were considered as having a functional disability. The analysis of variance (ANOVA) test and the binary logistic regression analysis were used to examine the factors associated with functional disability. Results Overall, 43.7% % (Male 42.9%, Female 44.5%) of the participants had a functional disability. Increasing age, being widowed, having no formal education, being underweight (body mass index (BMI) less then 18.5 kg/m2), and increasing numbers of morbidities were significantly associated with functional disability among the elderly in this study in age and gender-adjusted logistic regression analysis. Being ≥80 years was associated with a three-fold greater risk (OR=31.72, 95% CI=1.3-6.91) of functional disability than the youngest age group (60-69 years). On the other hand, the presence of more than five morbidities was associated with a nearly 20 times increased risk (OR=19.61, 95% CI=9.01-42.68) than those with zero to two morbidities. Conclusion A high proportion of the rural elderly residents of Dibrugarh had a functional disability. The study provides epidemiological evidence of the risk factors of functional disability in this setting. This epidemiological information may be useful for developing prevention strategies to reduce the burden of functional disability.Diarrhea is the principal cause of the majority of healthcare utilization. When diarrhea lasts longer than four weeks, it is considered chronic diarrhea. There are several causes of chronic diarrhea, but here we focus on one of the rare causes, known as McKittrick-Wheelock syndrome (MWS). We here present the case of a patient in his seventies with chronic diarrhea, found to have tubulovillous adenoma and diagnosed with McKittrick-Wheelock syndrome. We also discuss the clinical presentation, pathophysiology, and management of MWS.There are several well-described and studied autoimmune diseases that affect different organ systems, and a limited number of these affect the central nervous system. Autoimmune encephalitis represents a disease with a wide spectrum of clinical manifestations and different levels of severity, from mild cognitive impairment to complex encephalopathy. Immune-mediated encephalitis refers to a diverse and rare group of conditions in children associated with nonspecific symptomatology, altered mental state, and recalcitrant seizures. Infectious etiology must be excluded. Immune-mediated encephalitis syndromes could be associated with paraneoplastic or primarily autoimmune mechanisms. The newest scientific advantages have concluded that autoimmune encephalitis may be further divided into different groups of diseases depending on the immune response; examples are antibodies to cell surface proteins, antibodies to intracellular synaptic proteins, T-cell response with antibodies to intracellular antigens, among others. Treatment consists of supportive therapy, ranging from supplemental oxygen, fluid restriction to mechanical circulatory support. Specific treatment includes immunoglobulin infusion, plasmapheresis, and pulse steroid treatment. Prognosis is poor if specific treatment is not timely instituted. The diagnosis of autoimmune encephalitis could be challenging to clinicians due to its diverse clinical features, which can mimic a variety of other pathologic processes. Screening for cancer and proper management that includes immune therapy are fundamental, although some patients will need immune suppression for weeks or months as autoimmune encephalitis may relapse; therefore, follow-up is always necessary.Background Sucking habits are common among children, especially in early childhood. There is, however, controversy about its prevalence probably due to under-reporting. The objective of this study is to analyze the demographic factors, reasons for clinic attendance, and treatment options chosen by parents and health care providers to control digit sucking. Material and methods A retrospective cross-sectional study was conducted including 82 children presented to the paediatric clinic, Teaching Hospital, Batticaloa, with digit sucking over a period of three years from November 2017 to October 2020. The data was analyzed using SPSS version 19.0 (IBM Corp., Armonk, NY, USA). Results Eighty-two children were enrolled in this study. The majority (n=29, 35.4%) of them presented between seven months to two years, and very few (n=3, 3.6%) presented after five years. Female children outnumbered males (50 32). Only 24 (29.3%) mothers had been working and away from home during the daytime whilst the rest were housewivesuld be offered for persisting habitual digit sucking. Four children did not visit the dental department. Conclusions The majority of children presented to the clinic were below three years and females outnumbered males in all age groups. A greater number of children had been using their right hand and thumb. Most of them had the habit of sucking since birth and most of the parents anticipated mal-alignment of teeth due to consequences of sucking. None of them succeeded in stopping the habit of digital sucking with various remedies performed at home by their parents.T-cell prolymphocytic leukemia (T-PLL) is a very rare and aggressive lymphoproliferative disorder. We present a 70-year-old man with complaints of fatigue, low urinary output, and peripheral edema for one month. Objectively, he presented diminished respiratory sounds bilaterally and peripheral edema. Analytical study revealed mild anemia and mild lymphomonocytosis, acute kidney injury, and urinalysis with proteins, leukocytes, erythrocytes, and cylinders. Chest radiography was consistent with pleural effusion. Epigenetics inhibitor Subsequent study showed new onset of thrombocytopenia with a progressive increase of lymphocytosis, in association with inguinal adenopathies and splenomegaly. Immunophenotypic study of peripheral blood and lymph node biopsy were compatible with the diagnosis of T-PLL. Negative serology for human T-cell lymphotropic virus type 1 (HTLV-1) excluded adult T-cell leukemia. Progressive changes in the peripheral blood smear were seen, finally showing the presence of lymphocytes with a cerebriform nucleus, revealing this variant.
