Diabetes Mellitus as a Risk Factor for Tuberculosis: A Community Based Case Control Study.

Prevention of diabetes in the general population can help reduce the incidence of tuberculosis. Hence it is necessary to document that diabetes is strongly associated with tuberculosis as a risk factor. To study if diabetes is associated with tuberculosis compared to controls. A community based case-control study was carried out. 215 newly diagnosed cases of tuberculosis on treatment for not more than three months were selected randomly from the randomly selected tuberculosis unit. 215 neighbourhood controls were selected. They were matched for the age group of ± 10 years and sex. Fasting blood sugar (FBS) was estimated using a glucometer. Tobacco chewing, residence and family history of TB were significantly more in cases (P < 0.05). Mean BMI was significantly lower in cases compared to controls. The proportion of TB cases among the known cases of diabetes was 67% compared to 33% in controls, which was statistically significant. Mean FBS was significantly higher in cases compared to controls (P < 0.05). The odds of cases being diabetic was 2.456 times more than those of controls. On binary logistic regression, diabetes was an independent risk factor for tuberculosis. Other independent risk factors were tobacco chewing, and family history of TB. Family history of tuberculosis, and tobacco chewing were positively associated with tuberculosis whereas body mass index was negatively associated with tuberculosis. Diabetes was significantly associated with tuberculosis.

Socialization and Evaluation of The Level of Compliance of Tuberculosis Patients to The Use Anti-Tuberculosis Drugs to Pharmacy Students of The Lubuk Pakam Medical Health Institute in 2023

The incidence of Tuberculosis (TB) is a health issue that must be paid attention to, especially at the Limapuluh Community Health Center. This health center is a health service center in the Fifty District which experiences a high incidence of TB, with the number of TB cases in 2022 increasing from the previous year. The level of patient compliance with treatment is one of the determining factors for the success of therapy. This study aims to provide an understanding of the factors that influence the level of compliance of TB patients with the use of Anti-Tuberculosis Drugs (OAT) at the Limapuluh Community Health Center. The method of service carried out is in the form of communication, information and education related to the use of Anti-Tuberculosis Drugs. The socialization was carried out online through a zoom meeting with the presentation of material and continued with a pretest and posttest as a measuring tool regarding the increase in participants' understanding of the material presented. This activity was carried out on January 06, 2024 at 10.00-12.00 WIB. The results of this service are the counseling material provided to students seen from the posttest results which show that the understanding and increase in knowledge of the participants is good compared to the results of the previous pretest points. In conclusion, students who take part in this activity can further explore the factors that affect patient compliance in taking OAT drugs so that similar activities can be carried out regularly to prevent errors in the use of Anti Tuberculosis drugs.

Acute Leukemia and Latent Tuberculosis Infection in Italy: Quantiferon-Tb Test Screening in a Low Tuberculosis Incidence Country.

Identification of latent tuberculosis infection (LTBI) is a critical step of tuberculosis surveillance, especially in low-incidence countries. However, it is limited to situations with a higher probability of developing active disease, e.g., patients with hematological malignancies. According to guidelines, in TB non-endemic countries, no clear screening program is established at diagnosis for patients with acute leukemia (AL). The primary endpoint of this study was to establish the prevalence of LTBI in patients with a diagnosis of AL using QuantiFERON (QFT)-TB. Secondarily, radiological and clinical features driving the increased risk of LTBI were evaluated. QFT-TB screening was performed before induction or consolidation in all patients with AL (myeloid and lymphoid) treated at our Institution between October 2019 and August 2023. We accrued 62 patients, of whom 7 (11,3%) tested positive, without any symptoms or signs of active TB, and 2 (3,2%) resulted as indeterminate. All positive patients started prophylaxis with isoniazid 300 mg daily, while patients whose test was indeterminate did not receive any prophylaxis. Active TB was excluded by imaging, as well as microscopic, cultural, and molecular examination on bronchoalveolar lavage if signs of any infection were detected. During the 46 months of observation, no patients developed TB reactivation. Despite the low sample size, 1/10 of our patients had prior TB exposure, hinting that LTBI could be more common than expected in Italy. This finding suggests implementing TB screening in the pre-treatment setting, particularly at a time when more active treatments are becoming available also for patients ineligible for intensive chemotherapy.

Chronic Generalized Periodontitis in a Patient with Infiltrative Pulmonary Tuberculosis

Currently, the World Health Organization, in its annual Global Tuberculosis Report, notes an increase in the incidence of tuberculosis in the world associated with the failure of health systems. In 2022, 7.5 million people worldwide were diagnosed with tuberculosis, the highest rate since 1995. In the Russian Federation, the stabilization of reduced morbidity and mortality rates from tuberculosis infection is currently being determined. Patients with tuberculosis often have comorbid and concomitant diseases, which are one of the main causes that impressively affect the diagnosis and treatment of inflammatory periodontal diseases. There is a pathogenetic relationship and aggravation of the course of diseases. The aim of the study is to analyze the course of chronic generalized periodontitis in a patient with pulmonary tuberculosis and to select personalized therapy. A clinical case of combined pathology (dental and infectious diseases) is presented, which was observed on the basis of the pulmonary therapeutic department of the N.S. Pokhvisneva KUZ in the VOKPTD. The conducted studies allowed us to conclude about the positive effect of a personalized approach in treatment.

Trends of tuberculosis incidence among medical workers in the Vinnytsіa region

Trends of tuberculosis incidence among medical workers in the Vinnytsіa region

Uncommon presentation of gastrointestinal tuberculosis-A case series

Tuberculosis (TB) is a common disease in underdeveloped countries. Of all tuberculosis cases worldwide, 28% were reported from India. The most prevalent site of infection is the lungs (pulmonary TB), whereas extrapulmonary tuberculosis (EPTB) is less common. The most common form of EPTB in India is Lymph Node TB, which accounts for around 35% of total EPTB cases. Splenic tuberculosis incidence is 8 % whereas tuberculosis of pancreas and gall bladder is extremely rare. Pancreatic and gallbladder tuberculosis (GT) is extremely rare and presents with non-specific features. The clinical manifestations of EPTB are variable, imitate other diseases, and are usually confused with other diseases. Thus, it is crucial to be cautious and highly suspicious of EPTB infection in endemic areas. Probability of developing EPTB in immunocompromised patients is higher than in immunocompetent patients. The burden of EPTB in HIV patients ranges from 15 to 20% of all TB cases in HIV-negative patients, while in HIV-positive people, it accounts for around 40–50% of new TB cases. Histopathological examination (HPE) and positive Acid-Fast Bacilli (AFB) smears are used to make the diagnosis. ATT is given to such patients for 6 months. Due to such a diverse presentation of TB, here, we report a case series of extrapulmonary TB occurring in the abdomen in, pancreas, gallbladder, and spleen.

Communicable diseases in Ukraine during the period of 2018–2023: Impact of the COVID-19 pandemic and war

BackgroundBy examining 2018–2023 data, this study explored the intricate impact of the Russian invasion, ongoing COVID-19 pandemic, and environmental disruptions on communicable diseases in Ukraine. This conflict exacerbates challenges in disease surveillance and healthcare, compounding stress among the population. MethodsLeveraging the Centers for Disease Prevention Control's surveillance system, the study employs active and passive surveillance, utilizing medical records and laboratory reports. Notification rates gauge the incidence of communicable diseases, offering insights into trends during the study period. ResultsWhile salmonellosis, shigellosis, and rotavirus incidence are decreasing overall, there is a surge in viral hepatitis A, chronic hepatitis B, and C. This conflict hampers hepatitis C management, as evidenced by decreased numbers of treatment centers and patient enrollment. The prevalence of cough cases will increase in 2023, emphasizing the importance of sustained vaccination. The incidence of tuberculosis will increase in 2023 despite a general decrease. ConclusionThis study underscores the urgent need for sustained efforts and adequate resources, infrastructure, and international support to mitigate public health challenges in conflict-ridden Ukraine. Prioritizing vaccination programmes and enhancing healthcare accessibility in affected regions are crucial.

Utilizing whole genome sequencing to delineate relapse and reinfection tuberculosis on the Canadian prairies

RATIONALE Recurrent tuberculosis (TB) accounts for 5% of the Canadian TB burden. Recurrence can occur from relapse or reinfection. Identifying reinfection has implications for developing control policies. OBJECTIVE The objectives of this study were to quantify reinfection in recurrent TB using whole genome phylogenetic and single nucleotide polymorphism (SNP) and compare with epidemiological and clinical parameters from the Canadian prairies. METHODS DNA sequences of Mycobacterium tuberculosis isolates from recurrent TB cases along with epidemiological and clinical parameters were collected from Alberta and Saskatchewan. Inclusion criteria were two or more culture positive notifications age ≥17 years. SNP and phylogenetic tree scale differences (TIP) were used to determine the relapse and reinfection categories. RESULTS Of 7,627 notifications of TB disease, 533 were recurrent. 93 pairs (180 cases) were culture positive from which 26 (50 cases) were available for sequencing. 19 cases with SNP and TIP values ≤25 and ≤.001 were classified relapse. Seven SNP and TIP values >160 and >.001 were classified reinfection. Five of seven reinfections were Indigenous cases from high TB incidence areas. The non-sequenced and sequenced pairs differed only in age. CONCLUSIONS Recurrent culture positive TB is uncommon on the Canadian prairies and is more likely to be relapse. Reinfection is more likely in Indigenous persons living in high TB incidence communities. A limitation was the risk of selection bias since only 28% of eligible cases were sequenced. Since we did not know the non-sequenced reinfection risk, we could only conclude that the non-sequenced and sequenced categories were similar.

Factors Affecting Extrapulmonary Tuberculosis Reinfection in Pulmonary Tuberculosis Patients in Gorontalo City

Tuberculosis is a disease caused by the bacteria Mycobacterium tuberculosis. Tuberculosis does not only occur in the lungs, which is called pulmonary tuberculosis but can occur outside the lung organs, which is called extrapulmonary tuberculosis. Reinfection from Pulmonary tuberculosis to Extrapulmonary tuberculosis can occur due to several factors. This study aims to determine the factors that can influence the occurrence of reinfection Extrapulmonary tuberculosis in pulmonary tuberculosis sufferers. Method Analytical research with a cross-sectional approach. The number of samples was 49 samples of Pulmonary tuberculosis sufferers who underwent initial diagnosis at the Anatomical Pathology Laboratory, Prof. Dr. Hi. Aloei Hospital. Saboe Gorontalo City. The results of the study showed that the variables Adherence to treatment (p: 0.047), and BCG Vaccine (p: 0.018) were &lt; α value: 0.05, while the significance value of comorbidity for EPTB Reinfection was (p: 0.991). The conclusion is that adherence to treatment and the BCG vaccine have a significant effect on the incidence of reinfection Extrapulmonary tuberculosis (EPTB) in patients with pulmonary tuberculosis (PTB), while comorbidities do not have a significant effect on the incidence of reinfection Extrapulmonary tuberculosis (EPTB) in patients with pulmonary tuberculosis (PTB).

Insights into the Effects of Ligand Binding on Leucyl-tRNA Synthetase Inhibitors for Tuberculosis: In Silico Analysis and Isothermal Titration Calorimetry Validation.

Incidences of drug-resistant tuberculosis have become common and are rising at an alarming rate. Aminoacyl t-RNA synthetase has been validated as a newer target against Mycobacterium tuberculosis. Leucyl t-RNA synthetase (LeuRS) is ubiquitously found in all organisms and regulates transcription, protein synthesis, mitochondrial RNA cleavage, and proofreading of matured t-RNA. Leucyl t-RNA synthetase promotes growth and development and is the key enzyme needed for biofilm formation in Mycobacterium. Inhibition of this enzyme could restrict the growth and development of the mycobacterial population. A database consisting of 2734 drug-like molecules was screened against leucyl t-RNA synthetase enzymes through virtual screening. Based on the docking scores and MMGBSA energy values, the top three compounds were selected for molecular dynamics simulation. The druggable nature of the top three hits was confirmed by predicting their pharmacokinetic parameters. The top three hits-compounds 1035 (ZINC000001543916), 1054 (ZINC000001554197), and 2077 (ZINC000008214483)-were evaluated for their binding affinity toward leucyl t-RNA synthetase by an isothermal titration calorimetry study. The inhibitory activity of these compounds was tested against antimycobacterial activity, biofilm formation, and LeuRS gene expression potential. Compound 1054 (Macimorelin) was found to be the most potent molecule, with better antimycobacterial activity, enzyme binding affinity, and significant inhibition of biofilm formation, as well as inhibition of the LeuRS gene expression. Compound 1054, the top hit compound, has the potential to be used as a lead to develop successful leucyl t-RNA synthetase inhibitors.

Epidemiology and antimicrobial resistance of Mycobacterium spp. in the United Arab Emirates: a retrospective analysis of 12 years of national antimicrobial resistance surveillance data.

The Eastern Mediterranean Regional Office (EMRO) region accounts for almost 8% of all global Mycobacterium tuberculosis (TB) cases, with TB incidence rates ranging from 1 per 100,000 per year in the United Arab Emirates (UAE) to 204 per 100,000 in Djibouti. The national surveillance data from the Middle East and North Africa (MENA) region on the epidemiology and antimicrobial resistance trends of TB, including MDR-TB remains scarce. A retrospective 12-year analysis of N = 8,086 non-duplicate diagnostic Mycobacterium tuberculosis complex (MTB complex) isolates from the UAE was conducted. Data were generated through routine patient care during the 2010-2021 years, collected by trained personnel and reported by participating surveillance sites to the UAE National Antimicrobial Resistance (AMR) Surveillance program. Data analysis was conducted with WHONET, a windows-based microbiology laboratory database management software developed by the World Health Organization Collaborating Center for Surveillance of Antimicrobial Resistance, Boston, United States (https://whonet.org/). A total of 8,086 MTB-complex isolates were analyzed. MTB-complex was primarily isolated from respiratory samples (sputum 80.1%, broncho-alveolar lavage 4.6%, pleural fluid 4.1%). Inpatients accounted for 63.2%, including 1.3% from ICU. Nationality was known for 84.3% of patients, including 3.8% Emiratis. Of UAE non-nationals, 80.5% were from 110 countries, most of which were Asian countries. India accounted for 20.8%, Pakistan 13.6%, Philippines 12.7%, and Bangladesh 7.8%. Rifampicin-resistant MTB-complex isolates (RR-TB) were found in 2.8% of the isolates, resistance to isoniazid, streptomycin, pyrazinamide, and ethambutol, was 8.9, 6.9, 3.4 and 0.4%, respectively. A slightly increasing trend of resistance among MTB-complex was observed for rifampicin from 2.5% (2010) to 2.8% (2021). Infections due to MTB-complex are relatively uncommon in the United Arab Emirates compared to other countries in the MENA region. Most TB patients in the UAE are of Asian origin, mainly from countries with a high prevalence of TB. Resistance to first line anti-tuberculous drugs is generally low, however increasing trends for MDR-TB mainly rifampicin linked resistance is a major concern. MDR-TB was not associated with a higher mortality, admission to ICU, or increased length of hospitalization as compared to non-MDR-TB.

Impact of hyperglycemia on tuberculosis treatment outcomes: a cohort study

Hyperglycemia is prevalent and closely associated with pulmonary tuberculosis (PTB). This study aimed to investigate the effects of hyperglycemia on the outcomes of PTB treatment. This study comprised 791 patients with PTB in total. Patients with fasting plasma glucose levels of ≥ 6.1 mmol/L were diagnosed with hyperglycemia. Anthropometric and baseline demographic data were also collected. The treatment response was assessed based on clinical symptoms (sputum production, cough, chest pain, fever, hemoptysis, night sweats, loss of appetite, and fatigue), sputum smear, chest computed tomography (CT), and adverse gastrointestinal responses (vomiting, nausea, abdominal distension, diarrhea, and constipation). A generalized estimating equation (GEE) was used to evaluate these relationships. Hyperglycemia affected 266 (33.6%) of the 791 patients with PTB. In GEE analyses, patients with hyperglycemia exhibited a greater incidence of elevated tuberculosis (TB) scores (odds ratio (OR) 1.569; 95% CI 1.040–2.369), cough (OR 1.332; 95% CI 1.050–1.690), and night sweats (OR 1.694; 95% CI 1.288–2.335). Hyperglycemia was linked with a higher risk of positive sputum smears (OR 1.941; 95% CI 1.382–2.727). During therapy, hyperglycemia was also associated with an increased incidence of vomiting (OR 2.738; 95% CI 1.041–7.198), abdominal distension (OR 2.230; 95% CI 1.193–4.171), and constipation (OR 2.372; 95% CI 1.442–3.902). However, the CT results indicated that hyperglycemia did not affect pulmonary lesions in patients with TB. Patients with TB and hyperglycemia are at a higher risk of severe clinical manifestations, positive sputum smears, and adverse gastrointestinal effects and, therefore, the special situation of hyperglycemic patients should be considered in the prevention and treatment of TB.

Counseling on Pulmonary TB Overcoming and Healthy House Sanitation for Pulmonary TB Patients

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis and spreads through the air when sufferers cough, sneeze or spit. TB is still a global health problem with 10 million cases in 2019 and 1.4 million deaths. Indonesia has a high TB incidence rate, with 316 per 100,000 population in 2018. Environmental factors such as ventilation, floor type and residential density greatly influence TB transmission. This research was conducted Community Health Center to measure the knowledge and sanitary conditions of TB patients' homes. The methods used include interviews, counseling and direct observation of house conditions. The results show an increase in knowledge about TB after the education, with 75% of houses not meeting ventilation requirements, 8.9% of houses not meeting floor type requirements, 7.1% of houses not meeting wall type requirements, and 39.3% of houses having low occupancy density. not eligible. Good knowledge of a healthy environment and behavior that supports TB prevention is very important to reduce the transmission of this disease.

Current status of tuberculosis burden in China

Tuberculosis, caused by Mycobacterium tuberculosis, is an infectious disease that most often affects the lungs. China is still among the high-burden tuberculosis countries in the world. Although the estimated incidence of tuberculosis in China has declined in recent years, the declining rate is slow. It still faces major issues such as a slower rate of decline, a widening gap between estimated and notified incidence, higher risk among middle-aged and older adults, a high number of cases among agriculture and related workers, and a heavier disease burden in the country's western regions. In addition, latent tuberculosis infection, drug-resistant tuberculosis, tuberculosis coinfection with HIV, and extrapulmonary tuberculosis have also exacerbated the disease burden of tuberculosis to some extent. This paper reviewed the epidemic characteristics of tuberculosis, the epidemiological triad, three links and two factors in the transmission process, the disease burden, and other aspects to provide a reference for formulating prevention and control strategies on tuberculosis.

Progress Toward Tuberculosis Elimination and Tuberculosis Program Performance - National Tuberculosis Indicators Project, 2016-2022.

Elimination of tuberculosis (TB) is defined as reducing TB disease incidence in the United States to less than 1 case per million persons per year. In 2022, TB incidence in the United States was 2.5 TB cases per 100,000 persons. CDC's TB program developed a set of national TB indicators to evaluate progress toward TB elimination through monitoring performance of state and city TB program activities. Examining TB indicator data enables state- and city-level TB programs to identify areas for program evaluation and improvement activities. These data also help CDC identify states and cities that might benefit from technical assistance. The 5-year period for which the most recent data were available for each of five indicators: 1) overall TB incidence (2018-2022), 2) TB incidence among non-U.S.-born persons (2018-2022), 3) percentage of persons with drug susceptibility results reported (2018-2022), 4) percentage of contacts to sputum acid-fast bacillus (AFB) smear-positive TB patients with newly diagnosed latent TB infection (LTBI) who completed treatment (2017-2021), and 5) percentage of patients with completion of TB therapy within 12 months (2016-2020). The National TB Indicators Project (NTIP) is a web-based performance monitoring tool that uses national TB surveillance data reported through the National TB Surveillance System and the Aggregate Reports for TB Program Evaluation. NTIP was developed to facilitate the use of existing data to help TB program staff members prioritize activities, monitor progress, and focus program improvement efforts. The following five indicators were selected for this report because of their importance in Federal TB funding allocation and in accelerating the decline in TB cases: 1) overall TB incidence in the United States, 2) TB incidence among non-U.S.-born persons, 3) percentage of persons with drug susceptibility results reported, 4) percentage of contacts to sputum AFB smear-positive TB cases who completed treatment for LTBI, and 5) percentage of patients with completion of TB therapy within 12 months. For this report, 52 TB programs (50 states, the District of Columbia, and New York City) were categorized into terciles based on the 5-year average number of TB cases reported to National TB Surveillance System. This grouping allows comparison of TB programs that have similar numbers of TB cases and allocates a similar number of TB programs to each category. The following formula was used to calculate the relative change by TB program for each indicator: [(% from year 5 - % from year 1 ÷ % from year 1) × 100]. During the 5-year period for which the most recent data were available, most TB programs had improvements in reducing overall TB incidence (71.2%) and increasing the percentage of contacts receiving a diagnosis of LTBI who completed LTBI treatment (55.8%); the majority of programs (51.0%) also had improvements in reducing incidence among non-U.S.-born persons. The average percentage of persons with drug susceptibility results reported in most jurisdictions (28 of 52, [53.9%]) met or exceeded the 5-year national average of 97% (2018-2022). The percentage of contacts to sputum acid-fast bacillus (AFB) smear-positive TB patients with newly diagnosed latent TB infection (LTBI) who completed treatment increased in 29 of 52 (55.8%) jurisdictions from 2017 to 2021, signifying that, for most jurisdictions, steps have been taken to enhance performance in this area. The average percentage of patients with completion of TB therapy within 12 months was at or above the national average of 89.7% in approximately two-thirds (32 of 52 [61.5%]) of jurisdictions. This report is the first to describe a 5-year relative change for TB program performance. These results suggest that TB programs are making improvements in activities that help identify persons with TB and LTBI and ensure patients complete treatment in a timely manner. Use of NTIP data from individual TB programs enables a more detailed examination of trends in program performance and identification of areas for program improvement. Assessing indicator trends by TB program provides an opportunity to gain a better understanding of program performance in comparison to other programs. It can also facilitate communication between programs regarding successes and challenges in program improvement. This information is valuable for TB programs to allocate resources effectively and provide additional context on TB control for public health policymakers.

A dynamic hybrid model for efficient tuberculosis incidence rate prediction

ABSTRACT Tuberculosis remains a global health challenge, predicting its incidences is crucial for effective planning and intervention strategies. This study combines AutoRegressive Integrated Moving Average (ARIMA) and Nonlinear AutoRegressive with exogenous input (NARX) models as an innovative approach for TB incidence rate prediction. The performance of the proposed model (ARIMA-NARX) was evaluated using standard metrics (MSE, RMSE, MAE, and MAPE), and it was refined to achieve the best average predictive accuracies with an MSE: 0.0622, RMSE: 0.0851, MAE: 0.07520, and MAPE: 0.05535 followed by NARX 0.1597, 0.3189, 0.2724, and 0.3366, and ARIMA (2,0,0) 0.7781, 0.5959, 0.6524, and 0.6080 Models. These findings are expected to shed light on the TB incidence rate, providing valuable information to policymakers such as the World Health Organization (WHO) and health professionals. The developed model can potentially serve as a predictive tool for proactive TB control and intervention strategies in the region and the world at large.

Impact of Xpert MTB/RIF implementation in tuberculosis case detection and control in Brazil: a nationwide intervention time-series analysis (2011–2022)

Since 2014, Brazil has gradually implemented the Xpert MTB/RIF (Xpert) test to enhance early tuberculosis (TB) and drug-resistant (DR-TB) detection and control, yet its nationwide impact remains underexplored. Our study conducts an intervention time-series analysis (ITSA) to evaluate how the Xpert's implementation has improved TB and DR-TB detection nationwide. 1,061,776 cases from Brazil's National TB Registry (2011-2022) were reviewed and ITSA (2011-2019) was used to gauge the impact of the Xpert's adoption on TB and DR-TB notification. Granger Causality and dynamic regression modelling determined if incorporating Xpert testing as an external regressor enhanced forecasting accuracy for Brazil's future TB trends. Xpert implementation resulted in a 9.7% increase in TB notification and substantial improvements in DR-TB (63.6%) and drug-susceptible TB (92.1%) detection compared to expected notifications if it had not been implemented. Xpert testing counts also presented a time-dependent relationship with DR-TB detection post-implementation, and improved predictions in forecasting models, which depicted a potential increase in TB and DR-TB detection in the next six years. This study underscores the critical role of Xpert's adoption in boosting TB and DR-TB detection in Brazil, reinforcing the case for its widespread use in disease control. Improvements in prediction accuracy resulting from integrating Xpert data are crucial for allocating resources and reducing the incidence of TB. By acknowledging Xpert's role in both disease control and improving predictions, we advocate for its expanded use and further research into advanced molecular diagnostics for effective TB and DR-TB control.

Association of ambient temperature with tuberculosis incidence in Japan: An ecological study

ObjectivesAlthough several studies have investigated the effects of temperature on the incidence of tuberculosis (TB) in a single city or region, few studies have investigated the variations in this association using nationwide data. This study aimed to quantify the association between temporal variations in TB incidence and temperature across Japan. MethodsThe data on the weekly number of newly confirmed TB cases and meteorological variables in 47 Japanese prefectures from 2007 to 2019 were collected. The exposure-response relationships between TB incidence and temperature were quantified using a distributed lag nonlinear model for each prefecture, and estimates from all prefectures were then pooled using a meta-regression model to derive nationwide average associations. ResultsThis study included 335,060 patients with TB. Compared to those with minimum risk temperature on TB incidence (10th percentile at 4.45°C), people who were exposed to the highest temperature concentrations had a 52.0% (relative risk 1.52, 95% confidence interval 1.04-2.23) higher risk for TB incidence at the 99th percentile (30.1°C). Our results also emphasized the heterogeneity of these associations in different prefectures. Conclusions: Strengthening monitoring and public health strategies aimed at controlling temperature-related TB may be more effective when tailored to region-specific meteorological conditions.

Genital Tuberculosis as a Socially Significant Disease (Literature Review)

Globally, TB is the second leading cause of death from infectious diseases after COVID-19. Tuberculosis of the female genital organs is a type of extrapulmonary tuberculosis.It is known that both clinically pronounced and latent forms of this disease can cause both primary and secondary infertility due to pathogenetically caused disruption of the structure of the fallopian tubes and changes in the susceptibility of the uterine endometrium. It can be assumed that the problem of genital tuberculosis in Russia is still very relevant, although its true prevalence is unknown. This assumption is based on the facts of the projected growth of indicators the incidence of extrapulmonary tuberculosis, the obvious discrepancy between the real incidence and the official figures, as well as the increasing incidence of tubal-peritoneal infertility, which is often caused by genital tuberculosis. It is known that tuberculosis of the female genital organs is a difficult disease to diagnose. This is determined, in particular, by the fact that it does not have specific (so-called "marker") manifestations. Low rates of diagnosis of extrapulmonary forms of TB create a false sense of well-being, which does not reflect its true epidemiological picture. An obvious need today is the development of an optimal diagnostic complex, the use of which would contribute to accelerating the diagnosis of genital tuberculosis in women and, as a result, preventing the occurrence of irreversible changes in the female reproductive system caused by it. The authors used the scientific databases CyberLeninka, ELibrary and PubMed. Articles were searched for the following keywords: "tuberculosis", "genital tuberculosis", "infertility and tuberculosis". The paper analyzes articles published over the past 10 years.
