Abstract

Basal body temperature is the temperature when the body reaches the resting phase or does not perform any activity. Basal body temperature is influenced by factors such as the quality of a person's length of sleep, stress, and menstrual cycle patterns. The benefit of checking and monitoring basal body temperature for a woman is to determine when a woman starts to enter the ovulation period, making it easier for couples who want a target pregnancy. The measurement method was carried out in the morning right after waking up using a thermometer flanked in the armpit area by applying three repetitions of measurements within a period of two months with the number of sample participants of 10 cadet students of military biology study program with an age range of 19-21 years. This type of research is carried out observationally and analytically using longitudinal data. The analysis used in this study was by conducting a statistical mathematical model trial by analyzing the p-value. The results showed that in the paired test there was a significant influence of the relationship of basal body temperature on the menstrual cycle at the time before menstruation and when menstruation. The researcher's suggestion is to conduct further research with larger participants of samples and the presence of sample variations in observations because not all biologists do significant research with the statistical method.

Abstract

Health resilience refers to an individual's or a community's ability to withstand and recover from various health challenges and crises. Antibiotic resistance poses a significant threat to health resilience due to its impact on the effectiveness of antibiotics. The urgency of the issue of multidrug bacterial resistance in public health is a concern. The phenomenon discussed in this paper is related to the environment that becomes resistant to the antibiotic Staphylococcus aureus which causes high morbidity and mortality in animals such as chickens. In this study, there were three levels of antibiotic resistance based on clear zone media culture, namely resistance, intermediates, and sensitivity with each antibiotic totaling nine chicken cloacal swab samples. The purpose of this study was to determine the pattern of the significance of antibiotic resistance in S. aureus in three chicken farms in West Java Province (Bogor, Parung, and Sukabumi). This study used secondary data from previous studies and analyzed with nonparametric statistical methods using the Kruskal Wallis Test (One Way ANOVA). The results of the analysis showedalmost all gave a resistant response characterized by the absence of a clear zone in bacterial culture media treated with the same antibiotic in all chicken cloaca swab samples taken from farms in Bogor, Parung, and Sukabumi. Thus, resulting in the same resistance pattern. This indicates the pattern of the resilience of resistance in West Java is the same because the ecological conditions and living standards of the community are almost the same. These results may illustrate important concerns for the possibility of other regions in Indonesia having similar patterns of antibiotic resistance, so antibiotic use must adhere to appropriate guidelines to combat further antibiotic-resistant strains.

Abstract

Paronychia is an infection that occurs in the nail fold and the barrier between the nail and cuticle, is usually caused by penetrating trauma, which allows pathogens to infect and cause damage. The infection is caused by chemical factors, such as fungi, viruses, and bacteria, and risk factors, such as occupation, allergies, and finger-biting habits. Paronychia is a common nail infection that can significantly impact quality of life and work productivity, especially in certain occupations. Paronychia infection was differentiated by two categories, acute and chronic infection. The lack of knowledge regarding the prevention, cure, and rehabilitation of paronychia infection in Indonesia is the cause of the increasing cases of this infection. This review aims to provide knowledge for the Indonesian public and an opportunity for health workers to explore paronychia cases in Indonesia. The data in this paper were retrieved from 32 articles from 2014 - 2024 from PubMed, Cochrane, and Scopus. Articles were selected based on relevance to clinical cases of paronychia in humans, focusing on diagnosis, treatment and outcomes. Then, evaluate the causes, diagnosis, and treatment of paronychia using narrative review. Found that acute paronychia results from trauma or infection, while chronic cases are often caused by fungi. Treatment in acute paronychia is done with warm soaks and oral antibiotics, while chronic requires long-term topical corticosteroids and antifungal treatments. This review analyzes clinical cases of acute and chronic paronychia to evaluate their causes, diagnosis, and treatment. Further research is needed to advance the knowledge and treatment of paronychia infections.

Abstract

Tuberculosis (TB) remains a global health challenge, significantly impacting infectious disease mortality and morbidity. In the quest for effective diagnostic tools and precise treatment strategies, differential gene expression (DEG)-based biomarkers offer a promising avenue. These biomarkers provide specific insights into disease states and treatment responses by deciphering gene alterations within body cells. In this study, we aimed to identify immunological signatures associated with latent Mycobacterium tuberculosis infection in memory T cells. Leveraging transcriptomic analysis, we examined memory CD8 T cells from individuals with latent TB (NCBI-GEO GSM2643205) and healthy controls (NCBI-GEO GSM2643198). Our findings highlight candidate biomarker genes—LDB1, ZNF121, and STAT6—whose differential expression could significantly enhance our understanding of CD8 T cell genetic regulation during latent TB infection. These results hold promise for the development of more accurate biomarkers for diagnosing latent tuberculosis.
