Review
Homelessness increases the risk of acquiring an infectious disease. We conducted a systematic review of the literature to identify quantitative data related to infectious diseases and homelessness. We searched Google Scholar, PubMed, and SCOPUS for quantitative literature published from January 2003 through December 2022 in English from the United States and Canada. We excluded literature on vaccine-preventable diseases and HIV because these diseases were recently reviewed. Of the 250 articles that met inclusion criteria, more than half were on hepatitis C virus or . Other articles were on COVID-19, respiratory syncytial virus, , group A , mpox (formerly monkeypox), 5 sexually transmitted infections, and gastrointestinal or vectorborne pathogens. Most studies showed higher prevalence, incidence, or measures of risk for infectious diseases among people experiencing homelessness as compared with people who are housed or the general population. Although having increased published data that quantify the infectious disease risks of homelessness is encouraging, many pathogens that are known to affect people globally who are not housed have not been evaluated in the United States or Canada. Future studies should focus on additional pathogens and factors leading to a disproportionately high incidence and prevalence of infectious diseases among people experiencing homelessness.

INTRODUCTION
Peritoneal dialysis (PD)-associated peritonitis due to tuberculosis (TB) is associated with poor outcomes and optimal treatment strategies for this condition remain unknown. Our study aimed to: (i) systematically review the published literature on peritonitis caused by in patients on PD and (ii) review cases of peritonitis due to in patients on PD reported in Australia and New Zealand to determine the epidemiology, management strategies, and outcomes of this condition.
METHODS
A literature search of Medline, Scopus, Embase, ClinicalTrials.gov, Cochrane CENTRAL Register of Controlled Trials and Google Scholar for articles published from inception date to June 2022 was conducted. To be eligible, articles had to describe patient characteristics, initial anti-TB therapy, and treatment outcomes in all patients on PD with peritonitis caused by . Data from the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry of patients on PD who developed peritonitis due to between September 2001 and December 2020 were included and analyzed.
RESULTS
The systematic literature review identified 70 case studies (151 patients) and 8 cohort studies (97 patients), whereas the ANZDATA Registry identified 17 cases of peritonitis due to . Overall, in patients diagnosed with peritonitis due to , the rates of PD catheter removal and permanent transfer to hemodialysis (HD) were numerically higher in the ANZDATA Registry cases (82%) than in the case studies (23%) and cohort studies (20%). Observed all-cause mortality rates were also higher as observed in the case studies (33%) and cohort studies (26%) than in the ANZDATA Registry cases (6%).
CONCLUSION
Tuberculous peritonitis is uncommon in patients on PD and is associated with poor outcomes. Prospective studies are warranted to study the effect of retaining PD catheters after infection on patient outcomes.

BACKGROUND AND AIMS
Sepsis-induced immunosuppression appears to be reversible with immunomodulatory drugs. (MIP) stimulates the Th1 type of immune response. This systematic review and meta-analysis of randomised controlled trials (RCTs) was aimed to find out if MIP is effective at improving clinical outcomes in sepsis patients.
METHODS
The databases (PubMed, Google Scholar, Web of Science, and Cochrane Library), along with preprint servers until June 2023, were searched. The methodology was evaluated using the 'Cochrane Collaboration risk of bias-2 tool' for RCT. The study included patients more than 18 years of age with sepsis within 48 h of first organ dysfunction. The primary outcome was 28-day mortality, and secondary outcomes were the length of stay in the intensive care unit (ICU), days on vasopressor support, ventilator-associated pneumonia (VAP), secondary infections, catheter-related bloodstream infections (CRBSI), and the delta sequential organ failure assessment (SOFA) score.
RESULTS
The meta-analysis included two studies with 252 participants. In a pooled analysis, mortality in the MIP group was 43% lower than in the control (RR: 0.57, 95%CI: 0.33-1); however, this difference was statistically not significant. We observed the days on a vasopressor day (standardised mean difference [SMD]: 0.38; 95%CI: -1.20 to 0.44), length of ICU stay (SMD: 0.46; 95%CI: -1.44 to 0.51), secondary infection (RR: 0.75; 95%CI: 0.19-3.01), VAP (RR: 0.6; 95%CI: 0.28-1.56), CRBSI (RR: 0.97, 95%CI: 0.14-6.98), delta SOFA score (SMD: 0.88, 95%CI: -1.66 to - 0.10) between the two groups.
CONCLUSIONS
Our findings observed preliminary evidence in the trends for a positive association of MIP with better outcomes in sepsis patients.

BACKGROUND
Mendelian susceptibility to mycobacterial diseases (MSMD) is a rare clinical syndrome characterized by vulnerability to weakly virulent mycobacterial species, including Bacillus Calmette-Guérin (BCG) vaccines and environmental mycobacteria.
OBJECTIVE
We sought to perform a systematic review of the genetic, immunologic, and clinical findings for reported patients with MSMD.
METHODS
We searched PubMed, Web of Science, and Scopus databases for publications in English relating to MSMD. All full texts were evaluated for eligibility for inclusion. Two reviewers independently selected the publications, with a third reviewer consulted in cases of disagreement.
RESULTS
A primary systematic search and searches of other resources identified 16,155 articles. In total, 158 articles from 63 countries were included in qualitative and quantitative analyses. In total, 830 patients-436 males (52.5%), 369 females (44.5%), and 25 patients of unknown sex (3.0%)-from 581 families were evaluated. A positive family history was reported in 347 patients (45.5%). The patients had a mean age of 10.41 ± 0.42 (SEM) years. The frequency of MSMD was highest in Iran, Turkey, and Saudi Arabia. Lymphadenopathy was the most common clinical manifestation of MSMD, reported in 378 (45.5%) cases and multifocal in 35.1%. Fever, organomegaly, and sepsis were the next most frequent findings, reported in 251 (30.2%), 206 (24.8%), and 171 (20.8%) cases, respectively. In total, 299 unique mutations in 21 genes known to be involved in MSMD were reported: 100 missense (34%), 80 indel-frameshift (insertion or deletion, 27%), 53 nonsense (18%), 35 splice site (12%), 10 indel-in frame (2.7%), 6 indel (2%), and 15 large deletion/duplication mutations. Finally, 61% of the reported patients with MSMD had mutations of IL12RB1 (41%) or IFNGR1 (20%). At the time of the report, 177 of the patients (21.3%) were dead and 597 (71.9%) were still alive.
CONCLUSIONS
MSMD is associated with a high mortality rate, mostly due to impaired control of infection. Preexposure strategies, such as changes in vaccination policy in endemic areas, the establishment of a worldwide registry of patients with MSMD, and precise follow-up over generations in affected families, appear to be vital to decrease MSMD-related mortality.

Meta-Analysis
OBJECTIVE
We aimed to evaluate the sputum culture conversion time of DR-TB patients and its related factors.
METHODS
PubMed, The Cochrane Library, Embase, CINAHL, Web of Science, CNKI, Wan Fang, CBM and VIP databases were electronically searched to collect studies on sputum culture conversion time in patients with DR-TB. Meta-analysis was performed by using the R 4.3.0 version and Stata 16 software.
RESULTS
A total of 45 studies involving 17373 patients were included. Meta-analysis results showed that the pooled median time to sputum culture conversion was 68.57 days (IQR 61.01,76.12). The median time of sputum culture conversion in patients with drug-resistant tuberculosis was different in different WHO regions, countries with different levels of development and different treatment schemes. And female (aHR = 0.59,95%CI: s0.46,0.76), alcohol history (aHR = 0.70,95%CI:0.50,0.98), smoking history (aHR = 0.58,95%CI:0.38,0.88), history of SLD use (aHR = 0.64,95%CI:0.47,0.87), BMI < 18.5 kg/m (aHR = 0.69,95%CI:0.60,0.80), lung cavity (aHR = 0.70,95%CI:0.52,0.94), sputum smear grading at baseline (Positive) (aHR = 0.56,95%CI:0.36,0.87), (grade 1) (aHR = 0.87,95%CI:0.77,0.99), (grade 2) (aHR = 0.81,95%CI:0.69,0.95), (grade 3) (aHR = 0.71,95%CI:0.61,0.84) were the related factor of sputum culture conversion time in patients with DR-TB.
CONCLUSION
Patients with DR-TB in Europe or countries with high level of economic development have earlier sputum culture conversion, and the application of bedaquiline can make patients have shorter sputum culture conversion time. Female, alcohol history, smoking history, history of SLD use, BMI < 18.5 kg/m, lung cavity, sputum smear grading at baseline (Positive, grade 1, grade 2, grade 3) may be risk factors for longer sputum culture conversion time. This systematic review has been registered in PROSPERO, the registration number is CRD42023438746.

Meta-Analysis Review
Tuberculosis (TB) is a chronic, zoonotic infectious disease caused by that infects not only humans but also animals such as pigs, cows, buffaloes, sheep, and goats. Among them, pigs are one of the main food animals in the world. If pigs are infected with , meat products will be negatively affected, causing economic losses to the livestock industry. There is currently no systematic epidemiological assessment of swine TB in the world, so it is important to know the prevalence of swine, and these data are currently lacking, so we performed a statistical analysis. We searched 6791 articles and finally included data from 35,303 pigs from 15 countries or territories, showing a combined prevalence of TB in pigs of 12.1% (95% confidence interval [CI]: 9.2 to 15.9). Among them, the prevalence rate of swine TB in Europe was 15.2% (95% CI: 11.1 to 20.7, 2491/25,050), which was higher compared with other continents, and the difference was significant; the positive rate of PCR method was higher in the detection method subgroup, which was 15.7% (95% CI: 8.0 to 31.0, 376/2261); was detected in pigs in the typing group (9.5%, 95% CI: 6.7 to 13.5, 1364/21,430). The positive rate is higher compared with . This systematic review and meta-analysis is the first to determine the global prevalence of TB in swine herds. Although the seroprevalence of swine TB in this article is very low, the harm of TB cannot be ignored. It is important to take effective control and preventive measures to stop the spread of TB to reduce the impact of diseased pigs on animal husbandry and human health.

Meta-Analysis Review
BACKGROUND
Adherence is often a barrier to curative treatment of Mycobacterium tuberculosis (TB). There have been numerous interventions focused on increasing TB treatment adherence in Southeast Asia, but it is unclear if they are effective. This systematic review and meta-analysis aimed to compile and evaluate the literature on interventions designed to increase TB treatment adherence in Southeast Asia.
METHODS
We searched Cochrane Library Reviews (CDSR) and Cochrane Library Trials (CENTRAL), Medline, CINAHL, Scopus, and Web of Science from 2000 to 2022 with no language restrictions. We included studies of any design conducted in Southeast Asia that implemented interventions to increase treatment completion in people diagnosed with TB and assessed completion as an outcome. We did not require a control group. Four investigators used a standardized data collection form to collate results. The heterogeneity across studies was explored by I statistics. We assessed bias using the Newcastle-Ottawa Scale and Cochrane ROB 2.0. We used a random effects meta-analysis to calculate a pooled risk ratio with 95% confidence intervals.
RESULTS
From 1881 abstracts, we included 14 articles. There were 7198 subjects with 3163 (44%) receiving a TB treatment adherence intervention across eight countries. Interventions included directly observed therapy, text-message reminders, food incentives, and more. The risk ratio, derived from the meta-analysis of eight included studies with a control group and 6618 participants overall, was 1.04 (95% CI 1.01,1.08; I = 29%), favoring the interventions over controls with little concern for heterogeneity or risk of bias. When narratively assessed, the other six studies all reported increased adherence in the intervention group.
DISCUSSION
The results suggested there is a small, statistically significant benefit of using interventions to promote TB treatment completion. Future research could look at additional strategies and combinations of strategies to promote adherence.

Meta-Analysis Review
The occurrence rate of Haarlem and Beijing genotypes among Middle Eastern isolates of multi drug resistant Mycobacterium tuberculosis: A systematic review and meta-analysis.
Antibiotic resistance is a serious problem that poses a major challenge to tuberculosis control worldwide. Many developing countries still struggle with this infection in term of various aspects as it remains a major health concern. A number of developing countries are located in the Middle East, one of the world's most important regions. The control of this infection remains largely suboptimal despite intensive research in the field, and the mechanisms that lead to its progression have not yet been fully understood. Therefore, TB control must be amended through the identification of new strategies. For this reason, monitoring genetic characterizations of TB strains by molecular typing methods in different geographical regions can be important to setting local programs and global strategies to control TB infection. It is important to know the genotype of Mycobacterium tuberculosis strains to evaluate the occurrence of outbreaks and the transmission of this disease. Beijing and Haarlem genotypes are the most prevalent and, in these families, there is greater association with drug resistance, resulting in more severe forms of TB and higher levels of treatment failure than in other families. The current study is planned to systematically conduct a review using a meta-analysis to show the prevalence of Beijing and Haarlem genotypes in the Middle Eastern MDR-TB cases. M. tuberculosis strains pose particular epidemiological and clinical concerns as they can endanger tuberculosis control programs.

INTRODUCTION
The prevalence of diseases caused by non-tuberculous mycobacteria (NTM), including , is increasing, necessitating further information to guide prevention, control, and treatment strategies.
AREAS COVERED
A comprehensive analysis of articles published until February 2023 was conducted on PubMed, Web of Science, and Scopus databases to investigate antibiotic resistance in species. Stata software version 17 was employed for all analyses.
EXPERT OPINION
A total of 1647 articles were obtained through database search. After removing duplicates and unrelated studies, 17 cross-sectional studies that examined the breakpoints proposed by CLSI were included. The rates of resistance of to various antibiotics were as follows: clarithromycin (0%), rifampin (1%), amikacin (0%), ciprofloxacin (14%), linezolid (0%), moxifloxacin (0%), rifabutin (1%), doxycycline (96%), and SXT (49%). Our findings underscore the importance of managing and monitoring the use of these antibiotics, as well as the need for further studies to elucidate the exact mechanism of resistance to these antibiotics.

Meta-Analysis
Every year, 10 million people fall ill with tuberculosis (TB). Despite being a preventable and curable disease, 1.5 million people die from TB each year -making it the world's top infectious disease. TB is the leading cause of death of people with HIV and also a major contributor to antimicrobial resistance. Its presumed that TB was the cause of 1% of the total deaths among inpatients in Sudan in 2017. The current study is aimed to provide pooled prevalence of Mycobacterium tuberculosis among Sudanese as well as to determine any socio-cultural risk factors associated. A systematic review of the literature was conducted and regulated in accordance with the PRISMA Statement. After abstract and full text screening only twenty-six articles met our inclusion criteria and passed the quality assessment procedure. Pulmonary tuberculosis prevalence was assessed in sixteen included studies among participants from Khartoum, Gezira, Kassala, Blue Nile, River Nile, White Nile, Gadarif, Red sea, North Kordofan, Northern State, Sennar and West Darfur States, representing a total sample size of 11,253 participants of suspected individuals such as febrile outpatients, TB patients' contacts and other groups such as HIV/AIDS patients, hemodialysis patients, School adolescents as well as pregnant women. The pooled prevalence was 30.72% [CI: 30.64, 30.81]. Moreover, Khartoum State recorded the highest pooled prevalence as 41.86% [CI: 14.69, 69.02] based on a total sample size of 2,737 participants. Furthermore, male gender and rural residence were found to be significantly associated with TB infection. Further research with larger sample sizes targeting prevalence and risk factors of TB among Sudanese population is needed to be conducted.
