Auditory effects and consequences of noise pollution in humans: A scoping review

Published on: 9th November, 2020

OCLC Number/Unique Identifier: 8796529862

Noise is widespread in everyday life and can cause both auditory and non-auditory health impacts. Noise-induced hearing loss remains highly prevalent in occupational settings and is now increasingly caused by exposure to social and environmental noise. Incidence of noise-induced hearing loss (NIHL) has been observed to increase substantially in the recent years. Several advances have taken place in past few years for understanding the molecular basis of NIHL. Our understanding of molecular mechanisms implicated in noise-induced hair-cell and nerve damage has significantly increased. Research in the field of genetics is also advancing at a rapid speed, and several genes linked to NIHL have been discovered. This could help in developing preventive and treatment strategies. This review article focuses on the current research and future trends on auditory effects and consequences of noise pollution in humans, stressing the importance of adequate noise prevention and mitigation strategies as a public health measures.

Association between obesity profile and non-alcoholic fatty liver by race/ethnicity

Published on: 19th January, 2021

OCLC Number/Unique Identifier: 8897963456

NAFLD is characterized by accumulation of fat in the liver that can lead to health complications. Previous studies have found the obesity phenotype and its components to be risk factors for the development of NAFLD. This study aims to examine the relationship between the obesity phenotype and NAFLD among each racial-ethnic group. We analyzed data from the NHANES III survey (1988-1994). The obesity phenotype was defined based on BMI and metabolic syndrome. NAFLD was defined by abdominal ultrasounds among non-alcoholics with no infection or taking drugs affecting the liver. A higher prevalence of NAFLD was found among the metabolically unhealthy obese group (43.1%) and the metabolically unhealthy overweight (29.4%) than the metabolically unhealthy normal weight (11.8%). Mexicans-Americans had higher odds of NAFLD relative to whites (adjusted odds ratio (AOR) = 1.3, 95% confidence interval (CI) = 1.01-1.9, p = 0.04). The metabolically healthy obese phenotype was associated with NAFLD (p > 0.05) in the overall sample and in Whites. The metabolically healthy overweight was associated with NAFLD only among Mexican-American (p < 0.05). Metabolically unhealthy overweight or obese had higher odds of NAFLD relative to the metabolically healthy normal weight and this relation is consistent in all the racial/ethnic groups (p < 0.05). Metabolically healthy overweight and obese individuals had a high chance of NAFLD and it varied by race/ethnicity. Healthcare providers should pay more attention to care for those who are part of the metabolically healthy overweight or obese group especially among the Mexican-American population.

The Role of Genetic Mutations in the HPGD & SLCO2A1 Genes in Pachydermoperiostosis Syndrome

Published on: 1st May, 2025

Pachydermoperiostosis, also known as Primary Hypertrophic Osteoarthropathy (PHO), is a rare genetic disorder. The three main features are: enlarged fingertips (clubbing), thickened facial skin (pachydermia), and excessive sweating (hyperhidrosis). PHO is characterized by problems with skin and bone growth. Patients with PHO usually have coarse facial features with oily, thick, grooved skin on the face, joint pain, enlarged fingertips and toes, and hyperhidrosis of the hands and feet. Symptoms vary individually; however, men generally present with more severe manifestations. X-rays can help check for features that are not noticeable to the naked eye. There are two genes that are associated with PHO: the HPGD gene, located on the long arm of chromosome 4 at 4q34.1, and the SLCO2A1 gene, located on the long arm of chromosome 3 at 3q22.1 - q22.2. Mutations in the HPGD gene are inherited in an autosomal recessive manner, and the condition is sometimes abbreviated as PHOAR1 or Touraine-Solente-Gole syndrome.

Explicating the presentations of Acanthamoeba keratitis with special concern in the COVID-19 pandemic ambient

Published on: 18th March, 2021

OCLC Number/Unique Identifier: 8987259294

This article presents an overview of information regarding Acanthamoeba keratitis per epidemiology, host-pathogen interactions, clinical manifestations, risk factors, environmental implications, diagnosis, treatment and management as well as COVID-19 characteristics which may be taken into cognizance for suspected infected patients, researchers and ophthalmologic practitioners. Acanthamoeba spp. is pathogenetically ubiquitous in nature. Acanthamoeba keratitis is considerably an ocular-threatening and debilitating keratitis that exhibits contumacious characteristics which hinder or impede treatment or management. At inception, Acanthamoeba generally depicts atypical clinical features which are frequently misdiagnosed as other microbial keratitis. Fundamentally, it constitutes a rare corneal infection of which the aetiologic agent is the protozoon Acanthamoeba spp. in contact lens wearers, presenting features of severe ophthalmic distress, blurred vision, blepharospasm, ocular excoriation, extraneous entity sensation and photophobia culminating in aberrant visual functionality. These are perspicuously due to retarded prompt and adequate treatment and management. Personal and environmental hygiene, especially on the hands, face and ocular areas as advised for the COVID-19 protocol could prevent contamination and dissemination of Acanthamoeba keratitis infection. The differentiating relatedness of Acanthamoeba keratitis, COVID-19 ophthalmologic infections and other ocular problems may not have been clearly elucidated.

Navigating Weight Management with Stevia: Insights into Glycemic Control

Published on: 27th February, 2024

Stevia is a natural sweetener that has gained attention as a potential sugar substitute for glycemic control and weight management. Extensive research has shown that high sugar consumption is linked to obesity, dental caries, and other health issues. Stevia, derived from the Stevia rebaudiana plant, offers sweetness without calories and has a favorable glycemic profile. Studies have demonstrated its effectiveness in regulating blood glucose levels and reducing overall sugar and caloric intake. Consumer attitudes suggest a positive reception of Stevia as a sugar substitute among health-conscious individuals. However, further research is needed to understand its long-term effects and consumer sentiments. Future investigations should prioritize human clinical trials, targeted studies in diabetic populations, and exploration of Stevia’s interaction with gut microbiota, among other aspects. Stevia shows promise as a health-conscious alternative in glycemic control and weight management.

Death Wishes, Aging Patients, and Euthanasia

Published on: 12th March, 2024

The authors are searchers in psychopathology and communicate here about the dead wishes in relation to euthanasia. In Europe, the question comes regularly up to know if the law should be changed concerning the prohibition of euthanasia. The health system obeys progressively a modern idea of comfort and the “good life”. The authors are psychotherapists and their methodology is based mainly on phenomenological psychology, psychoanalysis, and psychopathology. Statistics of the French Ministry of Health will support their statements. Different clinical experiences with young patients, aging patients, or near-to-death patients are crossed and compared to those marked by heavy experiences like rape or amputation. The unbearable nature of their suffering makes them ask frequently to stop the pain. They would prefer being dead. This contribution examinates this kind of demand to find a helpful position for the caregiver and the patient. We should consider that near-death patients may often be at the climax of anxiety and depression is likely to switch over to dementia. In asking to finish with life, this purpose may change one day to another – sometimes it just highlights the wish to see things changed. The position of society and the medical staff has a high influence as well. Asking for euthanasia shows the variety of the same words that have different meanings from a medical, psychological, or psychopathological viewpoint. The purpose is to consider these aspects with the patient’s demand.

Role of T-Helper cells (CD4+ T Cells) in human immune system against some microbial infection: A mini review

Published on: 11th May, 2020

OCLC Number/Unique Identifier: 8601982623

The human immune system consists of innate and adaptive immune responses which both provide protective immunity to microbial infection. The adaptive immune system consists of T and B cell which act as second line defense through production of neutralizing antibody by B cells and cytotoxic activity of CD8+ T cells. The CD4+ T-cell performs a central role in the immune responses. These cells also known as T4 or helper/inducer T lymphocytes recognize antigens presented by antigen presenting cells (APC) such as macrophages and monocytes. Once antigens such as bacteria and viruses are presented, CD4+ T lymphocytes orchestrate the body’s antigen-specific immune response by Coordinating B-lymphocyte production of antibodies to these antigens, producing cytokines and induction of cytotoxic T-lymphocytes. The paper was aimed to review the role of T-helper cells (CD4+ T cells) in human immune system against some microbial infections.

Characterization of plastic degrading bacteria isolated from landfill sites

Published on: 28th May, 2020

OCLC Number/Unique Identifier: 8605989023

The plastic pollution is threatening the environment because it has very slow degradation rate and high usage in regular activities. The present study aims at the isolation of novel microorganisms that would assist faster degradation process of polyethylene. The waste samples were collected from different landfills and dumpsites. Out of forty samples, eight samples were found to degrade polythene strips in liquid medium. Further screening of these samples showed that two strains of microbes had high potential for polythene degradation. Biochemical tests and ribotyping were performed for characterization of isolated bacteria. Resultantly, two novel bacterial strains were identified named; Bacillus wudalianchiensis_UMT (2A) and Pseudomonas aeruginosa_UMT (6). Analysis of these microbes further revealed that Bacillus wudalianchiensis_UMT and Pseudomonas aeruginosa_UMT have capability to degrade 6.6% and 4.8% polyethylene respectively. So, the results disclosed that these bacteria have great potential to degrade polythene in less time as compare to natural degradation process and can contribute to reduce pollution from our environment.
