Awareness of CKD in people is crucial to decrease mortality, morbidity, and complications. CKD can lead to end-stage renal failure that needs renal transplantation. Objectives: This study aimed to evaluate the awareness of chronic kidney disease and the community's perception of organ donation and renal transplantation. Methods: This cross-sectional study was conducted on 503 Saudi adults between June and September 2022 in Riyadh Province of Saudi Arabia. We distributed online self-administered questionnaires among the general adult population utilizing convenient sampling. Results: Most of the participants had university degrees (67.2%). Of the total, 40.6%, 24.5% and 29.2% of participants knew that painkillers, hypertension (HTN) and diabetes mellitus (DM) are risk factors for CKD, respectively. A significant relationship was observed between knowledge about risk factors of CKD and educational level (p<0.05), but an insignificant relation with gender (p>0.05). Most of the participants (53.3%) supported organ donation, and a significant relationship was observed with the gender and educational level of participants (p<0.05). Conclusion: The current study showed low awareness of CKD and poor knowledge about kidney transplantation and organ donation in the community of Saudi Arabia. Mass media and campaigns can be central in raising awareness about CKD and organ donation to help facilitate disease identification and prevention.

Methods: A web-based and cross-sectional study (March to June 2022) was conducted in Saudi Arabia. The data collected from participants consist of demographics characteristics, menstruation experience, and vaccination status. The data was analyzed using R Statistical Software. Results: Of 538 participants included in this study, suspected cycle irregularities were prevalent in 47.6%, 44.6% and 41.1% of females after the first, second and booster doses of COVID-19 vaccine. Delayed menses (20.8%, 21%), less bleeding (9.5%, 11.3%) and too much bleeding (7.2% and 7.4%) were frequently reported cycle irregularities after the first and second doses of vaccines, respectively. However, irregular periods (variable pattern) were frequently (12.8%) reported following the booster dose.

Gym users use RM and PM as supplements for their workouts. This puts them at risk of developing cancer. \u0000Method: Self-administered questionnaires were used to evaluate the level of awareness, eating behaviors, and potential risks associated with specific foods among gym users in Saudi Arabia from November 2021 to August 2022. Demographic factors were also assessed, the questionnaire was distributed using online platforms including WhatsApp and Twitter.\u0000Results: In our study, 41.2% (n=123) and 70.8% (n=211) of the participants rarely consumed RM and PM per week, with the highest consumption of less than 500 g per week 31.9% (n=95) for RM. Only 7.4% (n=22) exceeded 1000 g of weekly RM and PM consumption. Maleness, high protein intake (>200 g/day), supplementary protein intake, good income (>5000 SAR) and being a healthcare worker were associated with higher RM consumption. In contrast, being a dietitian or sports coach was associated with less PM (p=0.045) consumption.

It is divided into several disease subcategories: acute otitis media (AOM), recurrent AOM, OM with effusion (OME), and chronic otitis media (COM). This study aims to determine the otitis media and identify the manner of prescribing antibiotics used for the treatment of OM cases in children from 3 months to 5 years old in Hera General hospital in Makkah city.\u0000Methods: The samples were retrospectively conducted at a tertiary General Hospital in the western region of Saudi Arabia. 113 records met the inclusion criteria for the study. Data were analyzed using descriptive statistics (percent and frequency). For quantitative data, the chi-square test and mean were used. \u0000Results: The number of OM cases was higher in patients aged 3 years old and less among age categories. The percentage of males (54.6%) was higher than females (45.4%). Amoxicillin-clavulanate was the most used treatment of OM in the inpatient ward, outpatient, emergency, and after discharge. The protocol of treatment was mostly by prescribing both antibiotics and analgesics without requesting any further samples to investigate the type of pathogen related to this infection. Cases presented to the emergency department were discharged with an antibiotic prescription without further investigation of the records for previous infection or recurrence.\u0000Conclusions: Due to increasing the antibiotics resistance alert around the globe, we believe that OM recurrence could be one of the community-acquired infections that affect the pediatric population and lower the quality of life and need specific attention from a physician who prescribes antibiotics for OM without further investigation.","PeriodicalId":428123,"journal":{"name":"Journal of Medicine and Health Studies","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126775262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pandemic has disproportionately affected certain sections of the global population, such as those living with type 2 diabetes, however, and this study thus aims to evaluate the effects of infection on individuals with type 2 diabetes, particularly those who are also smokers. The relevant review was thus done in two sections, one focusing on individuals with type 2 diabetes in general and the other examining people with diabetes who are also smokers. Twenty studies published between 2020 to 2021 were examined with respect to the impacts of SARS-CoV-2 on people with diabetes, including those who are also smokers. In general, people with diabetes were found to be more likely to be hospitalised when infected with SARS-CoV-2, as well as three times more likely than non-diabetics to have extreme outcomes such as requiring intensive care or even dying. The situation is a further 4.5 times worse for people with diabetes who are also smokers, creating profound economic implications faced for society.\u0000Conclusion: SARS-CoV-2 severely affects individuals with diabetes in terms of both health and logistics. A combination of SARS-CoV-2 infection and diabetes makes such individuals more susceptible to severe health outcomes, and these are further exacerbated by comorbidities such as smoking, underlying health conditions, ethnic and racial disparities, and a lack of access to high-quality health care.","PeriodicalId":428123,"journal":{"name":"Journal of Medicine and Health Studies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130831521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
