Background: The use of skin bleaching products is considered a common trend in dark-skinned women in West Africa, Surprisingly, only a few studies have been carried out on this subject in West Africa. The objectives of the study are to determine the prevalence, active component, complications, and mechanism of action of the key ingredients of skin bleaching products. Methods: This review article was conducted by searching PubMed (MEDLINE) and EMBASE using the search terms “ Use of skin bleaching products” and “West Africa” with a focus on articles from 2002 to 2022. Certain criteria were used to include or exclude articles from our study. Results: All articles reviewed revealed a rise in the prevalence of use of skin bleaching products ranging from 25% to 58.9% in women from Sub-Saharan Africa. The most common components found include hydroquinone, corticosteroids, mercury, and caustic agents. Some complications that result from the use of these products include skin atrophy, hyperpigmentation of skin around joints, Striae atrophicae, skin infection, and secondary adrenal insufficiency. Conclusion: The rise in the prevalence of the use of skin bleaching products in West African women has resulted in a corresponding rise in detrimental health conditions. Hence, Educating people concerning the harmful effects of the components of skin-lightening products should be employed and the government should put policies in place to reduce or legally prohibit the use of these products as the harm inarguably outweighs any perceived benefit.

A feared complication of ischemic cerebrovascular accident (CVA) is hemorrhagic transformation and it increases the length of hospital admissions, results in poor clinical outcomes and increases mortality. This study aims to identify risk factors of hemorrhagic transformation, discuss the pathogenesis of transformation and prognosis of the condition from original studies conducted within the past 10 years. PubMed and EMBASE are the major databases used. Eight articles met the inclusion criteria and are a mixture of retrospective and prospective studies. The sample size ranges from 32 to 1484 patients. Generally, the mechanism of hemorrhagic transformation identified involves the release of reactive oxygen species and metalloproteinase as a result of cerebral ischemia. Metalloproteinase further causes a breakdown of the extracellular matrix, thereby giving rise to the extravasation of cellular components. Some identified risk factors include: age, use of antithrombotic, the subtype of ischemic stroke, the severity of stroke and hypertension. Prognosis is linked to the type of hemorrhagic infarctions according to the European Cooperative Acute Stroke Study II (ECASS II) with patients with either hemorrhagic infarct type 2 (HI2) and parenchymal hematoma type 2 (PH2) having the worst functional outcome.

Prostate cancer remains the most common non-skin cancer in men. Prostate-specific antigen (PSA) is recognized as a biomarker for the diagnosis, monitoring, and risk prediction of prostate cancer. However, its role in prostate cancer screening has been controversial. While some authorities have recommended its use for screening, others have stated otherwise. Some clarity is required about its precise role in clinical practice. There need to be more consistent recommendations surrounding using PSA screening in clinical practice. Serum PSA measurements show variable reliability when screening for Prostate cancer, given the dynamics of PSA physiology and the conflicting results from two large, randomized control trials that sought to determine its role in prostate cancer screening and early detection. Hence surrogate measures like PSA density, PSA velocity, free-to-complexed PSA ratio, and percentage Pro-PSA among others, have been used to improve the predictive utility of this assay for Prostate cancer diagnosis. However, the debate on screening still lingers. The current review aims to highlight the controversies and objectively outline the current recommendations. This literature review examined scholarly papers and recommendations about the use of PSA for prostate cancer screening with the aim to rationalize the pros and cons of such approaches. We concluded that although more recent guidelines from the USPSTF recommend that screening be based on individual preference and professional judgment by the healthcare provider, differences in the specific details on how to best employ a PSA screening program still exist and require further review.

Children with autism spectrum disorder significantly suffer from other mental conditions, including anxiety and depression, compared to the general population. This continues to have a significant effect till adulthood. This study aimed at determining if there is a correlation between autism disorder in childhood and the development of anxiety and depression in adulthood and if behavioral therapy for children with this disorder reduces the likelihood of developing anxiety and depression as an adult. Three major databases were searched: EMBASE, Google Scholar, and PubMed, using specific search terms. Studies were selected according to population, exposure, comparison, condition or outcome(s) of interest, study design, and context. Overall, there are five articles relevant to this systematic review synthesis; all were observational studies. Our study shows psychiatric disorders like anxiety and depression could be related to autism spectrum disorder and early behavioral intervention could be beneficial and reduce the need for anxiety and depression medication.

Coronary heart disease (CHD) is one of the leading causes of morbidity and mortality worldwide. Dietary modifications in the form of a vegetarian diet can perhaps be the key to the prevention and management of cardiovascular diseases. The aims of this review are to determine the association between a vegetarian diet and CHD, to compare the risk of CHD in different types of vegetarian diets, and to assess variability in the biochemical predictors of CHD in the various vegetarian diets. Our study inferred that adherence to a plant-based diet was inversely related to the incidence of heart failure risk. Our research further supports the idea that a vegetarian diet is advantageous for the secondary prevention of CHD since it alters lipid profiles, lowers body mass index (BMI), and increases plasma antioxidant micronutrient concentrations. Additionally, eating a plant-based diet starting in adolescence is linked to a decreased risk of cerebrovascular disease (CVD) by middle age. An increase in sensitization and education efforts is imperative to ensure that people are appropriately informed about this option to significantly improve their quality of life.

Pancreatic cancer remains the third leading cause of death amongst men and women in the United States. Pancreatic ductal adenocarcinoma (PDAC), the most common type of pancreatic cancer maintains its reputation of being the most aggressive with a poor prognosis. One of the contributing factors to the high mortality of PDAC is the absence of biomarkers for early detection of disease and the complexity of tumor biology and genomics. In this review, we explored the current understanding of epigenetics and diagnostic biomarkers in PDAC and summarized recent advances in molecular biology. We discussed current guidelines on diagnosis, prognosis, and treatment, especially in high-risk individuals. We also reviewed studies that have touched on identifying biomarkers and the role they play in making early diagnosis although there are currently no screening tools for PDAC. We explored the recent understanding of epigenetic alterations of PDAC and the future implications for early detection and prognosis. In conclusion, the new and emerging advances in the detection and treatment of PDAC can lead to an improvement in the current outcome of PDAC.

Depression is a leading cause of disability worldwide and a major contributor to the overall global burden of disease. Although there are known, effective treatments for depression, people in low- and middle-income areas experience multiple barriers which limit their ability to receive adequate treatment. Some known barriers to effective care include a lack of resources, lack of trained healthcare providers, and social stigma associated with mental disorders and this creates gaps in mental health care and the need for more treatment modalities and adjuvant therapies to address these gaps. This review article was conducted using the scale for the assessment of non-systematic review articles (SANRA). We searched three databases; EMBASE, PubMed (MEDLINE), and Google Scholar using specified search terms. We had a total of nine articles with sample sizes ranging from 37 to 1551, and the age of participants ranged from 23 to 93 years. Articles were diverse in race and geographical locations. The articles were derived from cross-sectional studies, randomized studies, and experimental studies, and they focused on the relationship between humor and depression, and the reduced risk of depression in the study population. The articles identified different aspects of the relationship between humor and depression. The willingness of patients with depression to recognize or participate in humor could be defective resulting in abnormal social interactions such as withdrawal. However, there was some significant influence of humor or its styles on patients with depression either mitigating depressive symptoms or having no impact at all.

Cognitive behavioral therapy for psychosis (CBTp) as a modality of treatment is gaining attention. A number of authors have reported their experiences, including challenges, in administering CBTp for psychotic patients. With CBTp still evolving a lot more research is ongoing to fine-tune its benefits while mitigating the limitations to its use. The objectives of this review are to determine the role of CBTp in the overall improvement of a patient's quality of life, ascertain the number of hospitalizations with acute symptoms after the start of CBTp; and address the common drawbacks to CBTp in the management of psychosis. It was found that cognitive behavioral therapy (CBT) use can prevent the first episode of psychosis in ultra-high risk (UHR) and is effective in improving depression, self-esteem, and psychological well-being. Its use was associated with positive changes in thinking and mood, and sleep quality leading to improved everyday life. Patients who underwent CBT had fewer hospitalizations with a higher number of voluntary hospitalizations as compared to patients with usual care, who underwent a higher number of involuntary hospitalizations. Drawbacks included cost-ineffectiveness and resource limitation.

Lack of insight typically complicates psychiatric presentations, necessitating careful thought and planning to choose the best course of treatment. Exploring methods of medication administration techniques in the context of a lack of insight is crucial to achieving the ultimate goal of overcoming the insight barrier as rapidly as possible, which will result in therapeutic benefit. This study's objective was to systematically review the evidence on medication administration techniques in a backdrop of lack of insight and how that evidence was curated in the scientific literature. This study used the literature search strategy, which entails retrieving and analyzing the existing scientific literature pertinent to medication administration techniques for individuals with no insight between 2010 and 2022. Accessing online databases, such as PubMed, Google Scholar, and Medline was utilized in this study's literature search strategy. In our findings, in the primary evidence search, no randomized control trial (RCT) comparing the various models of medication administration with a lack of insight was found. No study provided data on the superiority of utility, quality of life, or efficacy outcome. Some 17 scientific papers were identified that cited various trials about lack of insight and medication use and met the inclusion criteria. We concluded that it could be challenging to administer medication to patients who lack insight. Nonetheless, progress has been made to mitigate this obstacle. Common moral values, common sense, medicolegal support, person-centered integrated care, and cutting-edge medication techniques may play a role. However, these models of medication administration are still evolving, along with the ethical concerns accompanying them. Hopefully, the available models discussed in this analysis will serve as a foundation for future developments. Nonetheless, much remains to be done. We encourage contemporary research to investigate safer and more dynamic methods that can alleviate this condition.

This study evaluates cellulose degrading bacteria isolates from paper mill dumpsites and their cellulolytic activity. Forty-one cellulose-degrading bacteria (CDB) were isolated from soil samples from seven different paper and pulp mill dump sites using enrichment method. The isolates were identified based on Morphology and Biochemical characterization while the identities of the potent cellulolytic bacteria isolates were confirmed by 16SrRNA sequencing. The optimum pH, temperature and incubation period for cellulose production by the CBD were determined. Isolates EFB3, ADB4, EFB1 and EFB4 exhibited the maximum zone of clearance around the colony with diameter of 50mm, 43mm, 44mm and 54mm and with the hydrolytic value of 10, 10.6, 8.8 and 7.6 respectively. The three selected bacteria with highest cellulose-degrading ability had 96% similarity with Enterobacter soli, Eubacterium ventriosum and Klebsiella michiganensis. Production of cellulase by the bacteria were influenced by environmental factors. Klebsiella michiganensis had optimum activity (38.5U/ml/min) after 72 hours while Enterobacter soli and Eubacterium ventriosum had optimum cellulase activity of 35.5U/ml/min and 32.2U/ml/min respectively after 48 hours. Enterobacter soli, Klebsiella michiganensis and Eubacterium ventriosum had optimum cellulase activity of 38U/ml/min, 35.6U/ml/min and 35.2U/ml/min respectively at pH7 while they recorded lower cellulase activity at acidic and alkaline pH ranges. Eubacterium ventriosum and Klebsiella michiganensis exhibited optimum activity of 25.12 U/ml/min and 20.55 U/ml/min respectively at 40°C. Enterobacter soli had the least cellulase activity with its optimum (15.02U/ml/min) at 35°C. The findings of this study revealed the abundance of bacteria equipped with the essential enzymatic capability to decompose cellulosic materials in the study area. These bacteria can also be used for mass production of cellulase.
