The seroprevalence of anti-Histoplasma capsulatum IgG antibody among pulmonary tuberculosis patients in seven referral tuberculosis hospitals in Indonesia.

BACKGROUND: Histoplasma capsulatum exposure is rarely suspected in Indonesia. Pulmonary histoplasmosis can occur simultaneously with pulmonary tuberculosis (TB) or as an alternative diagnosis in clinically-diagnosed TB patients with no microbiological evidence of TB. This study aimed to determine the seroprevalence of anti-H. capsulatum IgG antibody among pulmonary TB patients. METHODOLOGY: This was a sub-study of 306 participants from a prospective cohort pulmonary TB study conducted at seven TB referral hospitals in Indonesia. The study population was presumptive pulmonary TB adult patients who underwent microbiological TB examinations and were categorized as drug-sensitive (DS), drug-resistant (DR), and clinically-diagnosed TB. Anti-H. capsulatum IgG antibody levels at baseline were measured using MVista Histoplasma Ab enzyme immunoassays. Data were summarized using descriptive statistics. Bivariate and multivariate logistic regression analysis were performed to assess factors associated with anti-H. capsulatum IgG antibody positive result. RESULTS: 12.7% (39/306) of pulmonary TB patients were positive for anti-H. capsulatum IgG antibodies (DR-TB patients (15.9%, 18/114), DS-TB (13.0%, 15/115), and clinically-diagnosed TB (7.8%, 6/77)). The median unit value of anti-H. capsulatum IgG antibody for all positive samples was 15.7 (IQR 10.2-28.9) EU. This median unit value was higher in clinically-diagnosed TB patients compared to DS-TB or DR-TB patients (38.1 (IQR 25.6-46.6) EU, 19.7 (IQR 12.3-28.9) EU, and 10.9 (IQR 9.2-15.4), respectively). There were 10 patients (3.3%) with anti-H. capsulatum IgG antibody levels above 30 EU. Factors associated with the anti-H. capsulatum IgG antibody positive result were malignancies (OR 4.88, 95% CI 1.09-21.69, p = 0.037) and cavitary lesions (OR 2.27, 95% CI 1.09-4.70, p = 0.028). CONCLUSIONS: Our results provide evidence of exposure to H. capsulatum among pulmonary TB patients in Indonesia. Further studies are needed to provide a comprehensive picture of this fungal disease in other populations and regions to enhance awareness among clinicians and public health officials.

Attitude and level of COVID-19 vaccination and its determinants among patients with chronic disease visiting Debre Tabor Comprehensive Specialized Hospital, Northwest Ethiopia: A cross-sectional study.

INTRODUCTION: Coronavirus disease is a fatal viral disease caused by severe acute respiratory syndrome coronavirus 2. This study was aimed to assess the attitude, level of COVID-19 vaccine uptake, and its determinants among patients with chronic diseases visiting Debre Tabor Comprehensive Specialized Hospital, Northwest Ethiopia. METHODS: An institutional-based cross-sectional study was conducted among 422 randomly selected patients with chronic disease visiting Debre Tabor Comprehensive Specialized Hospital from February 1 to March 30, 2022. Bivariable and multivariable binary logistic regression analyses were done to identify associations between dependent and independent variables. RESULTS: Among all participants, only 29.6% of patients were vaccinated with any of the COVID-19 vaccines at least one dose. Age from 31 to 40 years (AOR = 6.26, 95% CI: 2.69-14.56), attended collage and above (AOR = 6.3, 95% CI: 1.37, 28.68), positive attitude towards COVID-19 vaccine (AOR = 9.07, 95% CI: 4.51-18.22), good knowledge (AOR = 7.63, 95% CI: 1.08-16.85), history of COVID-19 (AOR = 4.33, 95% CI: 1.85-10.17), family history of COVID-19 (AOR = 3.99, 95% CI = 1.89-8.48), ever been tested for COVID-19 (AOR = 0.33, 95% CI: 0.15-0.74) were determinant factors for COVID-19 vaccine uptake. CONCLUSION: COVID-19 vaccine uptake among patients with chronic disease was very low. The main reasons for not being vaccinated were doubts about vaccine efficacy, the vaccine may cause disease by itself, and fear of adverse effects. Therefore, different stakeholders should enforce vaccine uptake and awareness creation.

[Analysis on characteristic of pulmonary tuberculosis cases reported in children from four provinces in China, 2019-2021].

Objective: To analyze the reported characteristics of pulmonary tuberculosis (TB) in children aged 0-14 years in four provinces (municipalities), Beijing, Hubei, Chongqing and Sichuan, in China, and provide evidence for the prevention and control of pulmonary TB in children. Methods: The incidence data of childhood pulmonary TB were collected from notifiable disease and tuberculosis management information system of Chinese information system for disease control and prevention,and descriptive epidemiological methods were used to analyze the medical care seeking flow, characteristics and management inclusion of pulmonary TB cases in children. Statistical analysis and data visualization were conducted with softwares Excel 2015, R 4.1.2 and Echart 4.7.0. Results: A total of 6 811 pulmonary TB cases in children were reported in the four provinces during 2019-2021, in which 4 741 (69.6%) were clinically diagnosed and 2 070 (30.4%) were laboratory confirmed. A total of 526 medical institutions reported TB cases in children, including 356 general hospitals (67.7%, 356/526) reporting 4 706 cases, 11 infectious disease hospitals (2.1%, 11/526) reporting 836 cases and 5 children's hospitals (1.0%, 5/526) reporting 542 cases. A total of 6 249 (91.7%) local cases and 562 (8.3%) non-local cases were reported. The reported local incidence rates of TB from 2019-2021 were 6.20/100 000, 7.10/100 000 and 7.20/100 000, respectively, showing an increase trend year by year. The sex ratio of the cases were 0.98∶1(3 373∶3 438). The cases were mainly distributed in age group 10-14 years (4 887 cases, 71.8%). The cases were mainly students (5 167 cases, 75.9%). The management inclusion rates of the local cases and non-local cases were 20.60% and 2.67%, respectively. Conclusions: The main medical institutions reporting pulmonary TB cases in children were children's hospitals, infectious disease hospitals and TB special hospitals, the incidence of pulmonary TB in children in Sichuan was higher. In 2020, the inter-provincial medical seeking behavior of the pulmonary TB cases decreased significantly. The incidence rate in boys was lower than that in girls, and children aged 10-14 years were the population with high incidence of pulmonary TB. The management inclusion rate in non-local cases was lower than that in local cases.

Validation and comparative analysis of kogene mycobacterial interspersed repetitive unit-variable number of tandem repeat typing kit and its application on clinically isolated mycobacterium tuberculosis samples from national tuberculosis hospital, Republic of Korea.

Background: Tuberculosis (TB) remains a serious public health burden in Korea. Mycobacterial Interspersed Repetitive Unit-Variable Number Tandem Repeat (MIRU-VNTR) is preferred for epidemiological TB investigation. Until recently, the difficulty lies in epidemiological TB investigation due to the absence of commercialized MIRU-VNTR in Korea. Here, we have evaluated the newly designed MIRU-VNTR kit by Kogenebiotech, Korea. Materials and Methods: A total of 200 samples, where 100 are Mycobacrerium tuberculosis (M. tuberculosis), and the other 100 are non-M. tuberculosis, were used. Initially, the Kogenebiotech MIRU-VNTR typing kit (KoMIRU) was compared with Multilocus Variable Number Tandem Repeat Genotyping of M. tuberculosis typing kit (MVNTR) by Philip Supply for validation purpose. Then, Limit of Detection for DNA copies was optimized. Finally, KoMIRU and Genoscreen MIRU-VNTR typing kit (GeMIRU) were tested and comparatively analyzed for its specificity and sensitivity. Results: The study showed that the KoMIRU has slightly higher discriminatory power over MVNTR, 100% versus 97.5%. In comparative analysis, the KoMIRU has shown comparable capability as GeMIRU, showing 100% for sensitivity and specificity with a 95% CI value of 96.38 to 100.00%. Also, no discrepancies were observed on discriminated lineage strains between KoMIRU and GeMIRU. Out of 100, 84 were identified as Beijing strains, and remains were identified as NEW-1 (n = 8), Uganda (n = 6), East African Indian (EAI) (n = 6), Turkey (n = 2), and Haarlem (n = 1). Conclusion: In this study, KoMIRU has shown a comparable capability to GeMIRU. Furthermore, previous researches had suggested an association between lineage strains and drug resistance; hence, the implementation of KoMIRU can help in TB control and prevention.

Challenges to paediatric tuberculosis care as perceived by health workers in Kano, North-western Nigeria

uberculosis (TB) remains the world's deadliest infectious disease that affects a third of the world's population and newly infected an estimated 10 million people in 2018. The number of TB infected Nigerians ranks sixth in the world and first in Africa. Kano State has the highest Nigerian TB prevalence. I aimed to identify Paediatric TB care challenges as perceived by Kano Medical and DOT health care providers. The study design was prospective, descriptive and cross sectional involving structured questionnaire interviews of 43 healthcare providers, during TB supervision visits of 10 Health facilities in Kano. Generated data was entered, validated and analysed using the STATA 13 statistical software package. The sample size was convenient, since it is the number of all the health providers working in the facilities assigned to the author for supervision under a supervision contract with KNCV in 2017. Of the 43 respondents, there were 26 males, with a M: F ratio of 1.5: 1. Those health workers aged from 30 and 40 years constituted 58% of respondents. The staff cadre of respondents comprised of Community Health Extension Workers [CHEW] (40%), doctors (30%) and nurses (3%). Up to 51% of respondents had over 10 years health worker experience and greater than 36 months Child TB DOT care provision. The most commonly identified challenges to paediatric TB care included poor health knowledge (97.7%), poor health seeking behaviour (95.4%), poverty (95.4%), the inability of children to cough up sputum 95.4%, late presentation (90.7%), contact tracing logistics (90.7 %), patient and community factors of stigma and discrimination (86%) and poor health worker paediatric TB knowledge (70%). Perceived health worker challenges to effective Paediatric TB care were the adult orientation of the TB programme and its contact tracing logistic challenges, inadequate health worker Paediatric TB knowledge, children's inability to cough up sputum, poverty, poor patient TB health knowledge, community stigma and discrimination, poor health seeking behaviour and late presentation.

Incidence and Predictors of Poor Outcome amongChildhood Tuberculosis in the North of Cameroon

Background. Childhood tuberculosis (TB) has been neglected by TB programs in Sub-Saharan Africa. The aim of this study was to determine the incidence and predictors of poor outcome in children with TB in the North region of Cameroon. Methods.It was a retrospective cohort study based on hospital TB registers and treatment TB forms, in all of the 18 functional diagnosis and therapeutic centers (DTC) in the North region. All children aged 0-15years, on anti-TB treatment between 2010-2016 were enrolled. Logistic regression was used to find independent factors associated to poor outcome. Results. Of the 668 children included [321 (48.1%) boys], the median (25th-75thpercentile) age was 11(6-14) years, with 75.9% children aged >5 years. Pulmonary TB was the most common (62.9%) with 34.3% smear-negative pulmonary TB. Extrapulmonary TB (62.1%) was mostly found in children aged 0-5years. HIV/TB coinfection was 10.3%. Incidence (95%CI) of poor outcome was 4.0 %( 2.5-5.5%). Predictors [OR (95%CI)] of poor outcome were: HIV positivechildren [3.995(1.131-14.112), p=0.031], management in peripheral DTC [32.451(4.211-250.099), p=0.001], and transferred in patients from a peripheral zone toward a 3rdor 4thDTC category [4.602(1.092-19.386), p=0.037]. Conclusion.Incidence of poor outcome of childhood TB was quite low in the North region of Cameroon. HIV, peripheral TDC and transferred in patients were predictors of poor outcome. A better management of HIV, retraining DTC personnel and early reference from peripheral DTC would reduce poor outcome among childhood TB.

Adolescents in a tuberculosis hospital: Qualitative study of how relationships with doctors, caregivers, and peers mediate their mental wellbeing.

Lengthy hospitalization can impact adolescents' mental wellbeing in a number of negative ways. Scholarship has indicated that a young patient's relationships play an important role in reducing the amount of stress felt and in improving emotional state. In this article we turn to the experiences of adolescents with tuberculosis [TB] in Russia to explore how exactly hospitalization together with the TB diagnosis itself impact their mental wellbeing and how relationships with others mediate these impacts. We conducted a qualitative, interview-based study in Tomsk pediatric TB clinic. Interviews were conducted with three groups relevant for reaching the aim of this research: adolescent patients, their adult caregivers, and their treating physicians [17 informants in total]. Interview data were complemented with prolonged observations in the same clinic. The results of our study highlight that threats to mental wellbeing of adolescents with TB are multiple. Adolescents who are about to enter the in-patient treatment feel apprehensive and anxious about their future. They tend to have a hard time accepting their diagnosis, which they often feel is something shameful, and, consequently, may develop a negative attitude towards themselves. Most importantly, many undergo painful loss of personal relationships and expect or actually experience rejection by peers because of having tuberculosis. However, relationships with physicians, caregivers, and other patients in the clinic mediate negative impacts of TB diagnosis and hospitalization on adolescents' mental wellbeing and can open ways for providing support. Supportive practices include physicians leaving it up to adolescents to decide what they want to discuss and when, caregivers remaining available for contact and keeping regular communication, and other adolescents with TB proactively seeking contact with the newcomers and behaving in a non-judgmental way. These results can inform design of adolescent-friendly TB services.

Against settler colonial iatrogenesis: Inuit resistance to treatment in Indian Hospitals in Canada.

Canada's program to examine, transfer and treat Indigenous and Inuit peoples with tuberculosis in Indian Hospitals (ca. 1936 and 1969) has generally been framed by official narratives of population health, benevolence, and care. However, letters written by Inuit patients in Indian hospitals and their kin, and which were addressed to government officials and translated by government employees, challenge this assumption. By focusing on the harmful effects of the segregation and long-term detainment of Inuit peoples away from their communities, the letters theorize TB treatment as multiply harmful and iatrogenic. The letters also showcase how Inuit peoples resisted Indian Hospital treatment and articulated the need for care and treatment to occur within a network of intimate relations, rather than in distant sanatoriums.

Evaluation of the effect of the capitation compensation mechanism among pulmonary tuberculosis patients with a full period of treatment.

BACKGROUND: PTB is an infectious disease, which not only seriously affects people's health, but also causes a heavier disease economic burden on patients. At present, reform of the medical insurance payment can be an effective method to control medical expenses. Therefore, our study is to explore the compensation mechanism for pulmonary tuberculosis (PTB) patients with a full period of treatment, to alleviate the financial burden of PTB patients and provide a reference and basis for the reform of PTB payment methods in other regions and countries. METHODS: The quantitative data of PTB patients was collected from the first half of 2015 to the first half of 2018 in Dehui Tuberculosis Hospital in Jilin Province, and medical records of PTB patients registered in the first half of 2018 (n = 100) from the hospital was randomly selected. Descriptive analysis of these quantitative data summarized the number, cost, medication and compliance. Semi-structured in depth interviews with policymakers and physicians were conducted to understand the impact of interventions and its causes. RESULTS: After implementation of the compensation mechanism, the number of PTB patient visits in 2018 was increased by 14.2%, average medical costs for outpatients and inpatients were significantly reduced by 31.8% and 47.0%, respectively, and the auxiliary medication costs was reduced by 36.5%. Moreover, the hospital carried out standardized management of tuberculosis, and the patient compliance was very high, reaching almost 90%. CONCLUSIONS: The capitation compensation mechanism with a full period of treatment was a suitable payment method for PTB, and it is worthy of promotion and experimentation. In addition, the model improved patient compliance and reduced the possibility of drug-resistant PTB. However, due to the short implementation time of the model in the pilot areas, the effect remains to be further observed and demonstrated.

Interactive effect between temperature and fine particulate matter on chronic disease hospital admissions in the urban area of Tianjin, China.

This study focuses on effects of fine particulate matter (PM2.5) on chronic disease under different levels of temperature. We obtained type 2 diabetes, cerebral stroke and coronary heart disease hospital admissions (HAs) from five hospitals in urban Tianjin as well as the concentrations of PM2.5, nitrogen dioxide (NO2) and sulphur dioxide (SO2). We used distributed lag nonlinear models to explore nonlinear and lag effects of PM2.5. In single-pollutant models, PM2.5 was positively associated with type 2 diabetes, cerebral stroke and coronary heart disease HAs, with strongest effects at lag1, lag0 and lag06, respectively. The corresponding relative risk rates (RR%) were 1.836%, 2.083% and 6.428%. In co-pollutant models, the correlation between PM2.5 and HAs on high-temperature days was generally stronger than that on low-temperature days. This study indicated that PM2.5 can increase HA rates for these chronic diseases, and effects of PM2.5 on high-temperature days were stronger than that on low-temperature days.

Unidades de Enfermedad Renal Crónica Avanzada en España: una encuesta nacional sobre los estándares de estructura, recursos, resultados y seguridad del paciente / Advanced Chronic Kidney Disease Units in Spain: a national survey on standards of structure, resources, results and patient safety

ANTECEDENTES Y OBJETIVO: Recientemente, se han desarrollado en España las Unidades de Enfermedad Renal Crónica Avanzada (UERCA) con el objetivo de ofrecer una mayor calidad de vida a los pacientes con ERCA, mejorar su supervivencia y disminuir la morbilidad en esta fase de la enfermedad. Al día de hoy, hay poca evidencia en la literatura española e internacional con respecto a la estructura y cómo conseguir estos objetivos en las UERCA. Desde el grupo de trabajo ERCA de la Sociedad Española de Nefrología (SEN) se impulsa este proyecto para mejorar la atención a los pacientes ERCA a través de la definición de estándares de calidad para el funcionamiento de las UERCA. MATERIAL Y MÉTODOS: Se conformó una propuesta inicial de estándares de calidad sobre el funcionamiento de las UERCA a través de la consulta de principales fuentes de referencias y el asesoramiento de un grupo de trabajo de expertos a través de reuniones presenciales y no presenciales. A partir de esta propuesta inicial de estándares, se diseñó y envío una encuesta vía correo electrónico a 121 especialistas de nefrología y profesionales de enfermería con experiencia en UERCA españolas para conocer entre otros, la idoneidad de cada estándar, es decir, su obligatoriedad o recomendación como estándar. Se permitió acceso a la encuesta entre el 16 de julio de 2018, hasta el 26 de septiembre de 2018. RESULTADOS: Participaron un total de 95 (78,5%) profesionales de los 121 que fueron invitados a participar. De éstos, 80 fueron especialistas en nefrología y 15 profesionales de enfermería, obteniéndose una variada representación de profesionales de la geografía española. Tras analizar las opiniones de estos participantes, los estándares quedaron definidos a un total de 68, 37 de ellos (54,4%) obligatorios y 31 de ellos (45,5%) recomendables. Además, se observó que el volumen de pacientes atendidos en las UERCA se sitúa usualmente por encima de los 100 pacientes, y que el criterio de derivación por regla general está por debajo de 25-29 mL/min/1,73 m2 de filtración glomerular. CONCLUSIONES: Este trabajo constituye una primera propuesta de estándares de calidad para el funcionamiento de una UERCA en España. La definición de estos estándares ha permitido establecer las bases para la estandarización de la organización de las UERCA, y trabajar posteriormente en la configuración de un manual de estándares para la acreditación de estas Unidades

BACKGROUND AND OBJECTIVE: Recently, the Advanced Chronic Kidney Disease Units (UERCA, in Spanish) have been developed in Spain to offer a better quality of life to patients with advanced chronic kidney disease (ACKD), improving their survival and reducing morbidity in this phase of the disease. Nowadays, there is not much evidence in the Spanish and international literature regarding the structure and how to achieve these objectives in the UERCA. From the ERCA working group of the Spanish Society of Nephrology (SEN), this project is promoted to improve care for ERCA patients through the definition of quality standards for the operation of the UERCA. MATERIAL AND METHODS: An initial proposal for quality standards concerning the operation of the UERCA was configured through consultation with the main sources of references and the advice of an expert working group through face-to-face and telematic meetings. Base on this initial proposal of standards, a survey was conducted and sent it via email to 121 nephrology specialist and nursing professionals with experience in Spanish UERCA to find out, among others, the suitability of each standards, that is, its mandatory nature or recommendation as standards. The access to the survey was allowed between July 16th, 2018, until September 26th, 2018. RESULTS: A total of 95 (78.5%) professionals participated out of the 121 who were invited to participate. Of these, 80 of the participants were nephrology specialists and 15 nursing professionals, obtaining a varied representation of professionals from the Spanish geography. After analyzing the opinions of these participants, the standards were defined to a total of 68, 37 of them (54.4%) mandatory and 31 of them (45.5%) recommended. Besides, it was observed that the volume of patients attended in the UERCA is usually above 100 patients, and the referral criteria is generally below 25-29 mL/min/1.73 m2 of glomerular filtration. CONCLUSIONS: This work constitutes a first proposal of quality standards for the operation of UERCA in Spain. The definition of these standards has made it possible to establish the bases for the standardization of the organization of UERCA, and to subsequently work on the configuration of a standards manual for the accreditation of ERCA Units

Demographic profile, clinical and microbiological predictors of mortality amongst admitted pediatric TB patients in a tertiary referral tuberculosis hospital.

BACKGROUND: Pediatric tuberculosis (TB) constitutes 8% of the total caseload of TB. Children are particularly vulnerable to dissemination of disease and mortality. AIM: To determine mortality rate, elucidate type of TB, causes and predictors of mortality, if any, in admitted pediatric TB patients. METHODS: Present retrospective study was conducted in a tertiary referral center over last 6½ year on children who died out of total TB admissions. RESULTS: Out of total 1380 pediatric (<15 years of age) TB admissions, 74 children died, a mortality rate of 5.36%. Mean age was 11.4 years with highest mortality 47 (63.51%) in patients from 11 to 14 years age group. Significant majority 58 (78.38%) patients were females (p < 0.011). Range of hospital stay was 0-113 days with 7 (9.5%), 9 (12.16%) and 27 (36.48%) children dying on day of admission, next day and 3rd-7th day respectively, therefore a total of 43 (58.11%) died within first week of admission. Most 60 (81.08%) patients belonged to poor socio-economic status. History of contact was present in 12 (16.22%) cases while none had diabetes. 31 (41.89%) patients had sepsis and severe anemia (Hb ≤ 6 g %) was present in 6 (8.11%) patients at admission, out of which 4 died on the same day of admission, even before blood could be arranged. Most patients 68 (91.89%) had pulmonary TB with 25 children having concomitant extrapulmonary involvement, while 4 (5.41%) had meningeal TB and 2 (2.70%) had disseminated TB with HIV. Microbiological confirmation was achieved in 51 (68.92%) (48 PTB and 3 EPTB) cases while 23 (31.08%) were clinically diagnosed. Bilateral extensive fibro-cavitary disease with infiltrations was the commonest. Drug resistance was confirmed in 21 (28.38%) with 2, 5, 8, 5 and 1 patient diagnosed with mono H, RR, MDR, pre-XDR and XDR respectively but results of 9 patients were received posthumously. Treatment given was category 1, category 2 and regimens for drug resistant TB in 24 (32.43%), 29 (39.19%) and 21 (28.37%) cases respectively based on prior history of ATT and drug sensitivity. Adverse drug reactions were noted in 12 (16.21%) cases. Noted immediate causes of mortality were cardio-respiratory failure, sudden pneumothorax, massive hemoptysis, sepsis, extensive pulmonary disease and aspiration pneumonia. The pointers towards mortality include female gender, severe malnutrition, anemia, extensive disseminated disease and drug resistant TB. Ignorance, dependency of children on parents, poor adherence and late referrals into the system lead to delayed diagnosis and initiation of proper regimen based treatment. CONCLUSION: Early referrals of non-responders and failures to centers equipped with programmatic management facilities are essential for proper, timely management of pediatric TB to reduce mortality.

Detection of airborne bacteria from patient spaces in tuberculosis hospital.

Background: The spread of nosocomial bacterial infection greatly threatens public health and the impact of nosocomial infection worsens if highly pathogenic bacteria, Mycobacterium tuberculosis as an instance, involves. In this study, we have investigated the presence of airborne M. tuberculosis in a specialized tuberculosis hospital. Methods: The study sites selected were waiting room I, II, and ward VI patient lounge, Masan National Tuberculosis Hospital, where the modern ventilation system is on the operation for opportunistic infection prevention. The air samples were collected from the different sites three times for 1 day, and after air collection, air sampled disposable filter membrane was incubated for 4 weeks on nine Middlebrook 7H11 agar plates. Results: Our data showed that out of nine incubated 7H11 plate agars, four plates showed bacterial growth and these grown bacterial colonies were isolated and identified. Among bacterial species identified, there was a colony of Mycobacterium mageritense, one of nontuberculous Mycobacteria. Although there was no M. tuberculosis, the cause of tuberculous disease and transmitted through the nosocomial infection, all pathogens detected were known to be associated with nosocomial infection. Conclusions: Hospitals dealing with infectious diseases should always be wary that ventilation system does not guarantee safety from airborne pathogen exposure hence should continuously monitor the presence of other hospital-associated infection causing pathogenic microorganisms.

Epidemiological Trends in the Form of Childhood Tuberculosis in a Referral Tuberculosis Hospital in Shandong, China.

BACKGROUND: In China, the prevalence of tuberculosis (TB) diseases and epidemiological trends in the TB forms among children are still unclear; a retrospective study was conducted aiming to assess it. METHODS: Between January 2007 and September 2020, 1577 consecutive childhood TB patients (aged ≤ 15 years) were included in the study. Data, including demographic information and underlying diseases, were collected from medical records. Then, patients were categorized and reported according to the anatomical site of TB disease. To analyze the epidemiological trends in the proportion of each form of TB disease, a linear-by-linear association was used, and a P value of <0.05 was considered to indicate that a significant change had occurred in the proportion of TB disease over the studied period. RESULTS: During the fourteen-year study period, a total of 1577 children patients were enrolled, including 954 boys (60.5%) and 623 girls (39.5%), with a mean age of 9.26 ± 5.18 years. Among the studied patients, 810 (51.4%) patients have pulmonary TB, 1137 (72.1%) have extrapulmonary TB, 372 (23.6%) have both conditions, and another 765 (48.5%) extrapulmonary cases presented in isolated form. Pleural TB (29.0%) and tuberculous lymphadenitis (23.7%) were the most frequent two forms of childhood TB. In addition, during the past decade, the proportions of pulmonary TB, pleural TB, and tuberculous lymphadenitis showed an increasing trend (all P < 0.05). However, no significant trends in the proportions of other forms of TB disease, such as extrapulmonary TB (P > 0.05), tuberculous meningitis (P > 0.05), endobronchial TB (P > 0.05), and disseminated TB (P > 0.05), were found. CONCLUSION: Our findings suggest that childhood TB is facing new challenges, and the policy should be adjusted timely to fit the real situation.

Clusters of COVID-19 in long-term care hospitals and facilities in Japan from 16 January to 9 May 2020.

AIM: To clarify the association of cluster number and size of coronavirus disease 2019 (COVID-19) in long-term care (LTC) hospitals/facilities, general medical/welfare facilities and non-medical/welfare facilities with morbidity and mortality in 47 prefectures during 16 January to 9 May 2020 in Japan. METHODS: Information on COVID-19 clusters (n ≥2), and morbidity and mortality of COVID-19 was collected. RESULTS: A total of 381 clusters with 3786 infected cases were collected, accounting for 23.9% of 15 852 cumulated cases on 9 May 2020. Although the cluster number (/107 subjects) in LTC hospitals/facilities was significantly smaller compared with those in the other two groups, the cluster size in LTC hospitals/facilities was significantly larger than that in non-medical/welfare facilities. Cluster numbers in general medical/welfare facilities and in non-medical/welfare facilities were significantly positively correlated with morbidity (/105 ), indicating relatively early identification of clusters in these facilities. Unlike in these facilities, cluster size in LTC hospitals/facilities was significantly positively correlated with morbidity, indicating that clusters in LTC hospitals/facilities were finally identified after already having grown to a large size in areas where infection was prevalent. Multivariate logistic regression analysis showed that both cluster number and cluster size only in LTC hospitals/facilities were independently associated with higher mortality (≥median 0.64/105 subjects) after adjustment. CONCLUSIONS: Preventive efforts against COVID-19 outbreaks even at the early phase of the epidemic are critically important in LTC hospitals/facilities, as both the larger number and size of clusters only in LTC hospitals/facilities were independently linked to higher mortality in prefectures in Japan.

Tuberculosis in Iran: a historical overview from al-Tabari, Rhazes, Avicenna and Jorjani to Abolhassan Ziya-Zarifi. Old and new pioneers in the fight against tuberculosis: challenges, pitfalls and hopes.

Tuberculosis is a serious respiratory infectious disease, caused by Mycobacterium tuberculosis bacteria. It has always represented a permanent, serious public health challenge over the course of human history, because of its severe epidemiological, clinical and societal implications. The present review aims at over-viewing the contributions of the Iranian medicine to the control, management and treatment of tuberculosis, from the glorious past of the eighth-ninth centuries to the present, from Ali Abu al-Hasan Ahmad ibn Sahl-e Rabban al-Tabari to Rhazes, Avicenna, Jorjani and Abolhassan Ziya-Zarifi. However, despite the efforts, tuberculosis and, in particular, multidrug-resistant tuberculosis still represent a great public health concern in Iran. On the other hand, this country can capitalize on its millennial, incredibly rich story of major achievements in the battle against tuberculosis to develop and implement ad hoc public health programs for the control of the disorder, including targeted and specialized interventions.

Tuberculosis in Siena: evolution of the disease and its treatment, from the Unification of Italy to the 1930s.

Between the end of the nineteenth century and the first half of the twentieth century, the city of Siena experienced elevated tuberculosis-related morbidity and mortality, to the point that on January 1, 1929 the newspaper La Nazione wrote that "Siena ranks second in the official Tuberculosis (TB) incidence rate". The author presents statistical data relating to a time span ranging from 1898 to 1935, interpreting them in light of social and sanitary conditions found in the city. The result is an exhaustive picture of the most important actions implemented at city level to prevent tuberculosis and to assist and treat the sick, such as: the creation of seaside hospices conceived by Carlo Livi for children suffering from scrofula, as well as centers committed to the prevention of childhood poverty and malnutrition; the realization of activities in the green areas of the ramparts of the Fortress, upon recommendation by the great hygienist Achille Sclavo; the establishment of a Preventorium on the premises of the Monastery of Santa Maria Maddalena to accommodate children from families that included pulmonary tuberculosis patients, and countless activities carried out by the Anti-TB Dispensary. Of particular interest is the identification of the main cause of high TB incidence in the unhealthy houses located in some areas of Siena's district, which, in 1930 engendered a lively debate hinging upon the notion of building restoration.

Melanoma cutáneo asociado a la mutación del gen BRAF en dos hospitales de la ciudad de Guatemala / Cutaneous melanoma associated with the mutation of the BRAF gene in two hospitals from Guatemala City

Los estudios de melanoma en Guatemala han sido pocos y únicamente se ha evaluado el aspecto clínico e histológico. El objetivo del presente estudio fue determinar la proporción de casos de melanoma cutáneo por morfología, inmunohistoquímica y mutación del gen BRAF en pacientes con diagnóstico de melanoma en dos centros de referencia, Instituto de Cancerología e Instituto de Dermatología en Guatemala. El estudio es de tipo descriptivo, retrospectivo, transversal. El tipo de muestreo es no probabilístico, con una muestra por conveniencia de 100 casos de tejidos de piel de pacientes, caracterizados por edad, sexo y localización del tumor. Los estudios moleculares incluyeron la determinación de la mutación de la proteína BRAF, por la técnica de PCR-RT. Los resultados muestran que el sexo más afectado es el femenino (54 %). El grupo etario con mayor número de casos es entre 56-75 años (44 %). El tipo histológico predominante es el melanoma lentiginoso acral (59 %) y la localización más frecuente es en miembro inferior (71 %). No se encontraron casos de melanoma lentigo maligno. La mutación del gen BRAF se encontró en el 6 % de los casos, lo que representa un dato importante para el pronóstico y tratamiento del paciente. Por ser uno de los primeros estudios que incluyen el factor molecular, abre paso a una línea de investigación que permita dar continuidad a los pacientes con melanoma en Guatemala, lo que permitirá determinar factores pronóstico y predictivos, así como tratamientos de los casos en estudio.

Studies of melanoma in Guatemala have been few and only the clinical and histological aspects have been evaluated. The objective of this study was to determine the proportion of cases of cutaneous melanoma by morphology, immunohistochemistry and mutation of the BRAF gene in patients diagnosed with Melanoma in two important reference centers, Institute of Cancerology (Incan) and Institute of Dermatology of Guatemala (Inderma). The study is descriptive, retrospective, transversal. The type of sampling is non-probabilistic, with a convenience sample calculation of 100 cases of patient skin biopsies, characterized by age, sex and tumor anatomic location. Molecular studies included the determination of the BRAF protein mutation by means of the RT-PCR technique. Results show that the most affected sex is the female (54 %). Age group with the highest number of cases is between 56 and 75 years old (44 % of cases). The histological type that predominated is acral lentiginous melanoma (59 %) and the most frequent location is in the lower limb (71 %). No cases of malignant lentigo melanoma were found in the cases studied. The BRAF gene mutation was found in 6 % of the cases, which represents an important data for the prognosis and treatment of the patient. In addition, being one of the first studies that include the molecular factor, it opens the way to a line of research that allows patients with melanoma to continue in Guatemala. This would allow to determine prognostic and predictive factors, as well as treatments of the cases under study.

Efectividad de la implantación de una gestión clínico-epidemiológica durante la Covid-19 en un hospital de media-larga estancia / Effectiveness of the implementation of clinical-epidemiological management during Covid-19 in a medium-long-stay hospital

OBJETIVO: Los efectos de la emergencia sanitaria por la Covid-19 han demostrado la alta vulnerabilidad de las personas que residen en centros de media y larga estancia, con altas tasas de mortalidad. Se disponen de pocos datos acerca de los protocolos de contingencia para minimizar la propagación del virus en estos centros. El objetivo de este estudio fue describir las características clínicas y epidemiológicas de los pacientes afectados por el SARS-CoV-2, así como las medidas preventivas y de gestión adoptadas en el Hospital Nacional de Parapléjicos (Toledo) para minimizar el riesgo de transmisión de la Covid-19. MÉTODOS: Un equipo formado por especialistas en Medicina Preventiva y en Medicina Interna del Hospital Nacional de Parapléjicos estableció un protocolo de vigilancia activa, identificación de casos sospechosos y confirmados, así como de seguimiento de contactos. Además, se creó una Unidad para la atención de los casos confirmados, con personal formado específicamente en Covid-19, para intentar lograr una mejor atención de los pacientes y optimización de los recursos materiales disponibles. Para el análisis de los datos se han utilizado medidas estadísticas descriptivas. RESULTADOS: La prevalencia de la Covid-19 fue del 12,2%, con una incidencia acumulada del 8,2%. Tras la instauración del protocolo se logró el control de la enfermedad, sin transmisión intrahospitalaria posterior a su aplicación. Debido a la alarma generada al inicio de la pandemia, hasta un 45% de las RT-PCR solicitadas no cumplían los criterios del Ministerio de Sanidad, siendo todas negativas. Las características clínicas de nuestros pacientes difirieron ligeramente de las observadas en otros estudios publicados en población general, siendo la tos y la astenia los síntomas más frecuentes, presentes en el 69,2% y el 38,5% respectivamente. El 100% de los pacientes infectados no presentaron complicaciones que precisaran asistencia en Unidad de Cuidados Intensivos. CONCLUSIONES: Con la aplicación de las acciones preventivas y organizativas consideramos que hemos presentado una incidencia baja de infectados. Es indispensable la elaboración de protocolos y su supervisión para la rápida identificación de casos y optimizar las pruebas solicitadas. Pese a ser un hospital de media y larga estancia, no hemos presentado mortalidad ni complicaciones que requirieran ingreso en Unidad de Cuidados Intensivos

OBJECTIVE: The effects of the Covid-19 health emergency have demonstrated the high vulnerability of people residing in medium and long-stay centers, with high mortality rates. Little data is available about contingency protocols to minimize the spread of the virus in these centers. The goal of this study was to describe the clinical and epidemiological features of patients affected by SARS-CoV-2 and the preventive and management measures adopted at the National Hospital for Paraplegics (Toledo, Castilla-La Mancha, Spain) to minimize the risk of transmission of Covid-19. METHODS: A team of specialists in Preventive and Internal Medicine established a protocol for active surveillance, identification of suspected and confirmed cases, and follow-up of contacts. Also, a Unit for the care of confirmed cases was created with personnel specifically trained in Covid-19, to achieve better patient care and optimize the available resources. Descriptive statistical measures have been used to analyze the data. RESULTS: The prevalence of Covid-19 was 12.2%, with a cumulative incidence of 8.2%. After the protocol was established, control of the disease was achieved without hospital transmission after its application. Due to the alarm generated at the start of the pandemic, up to 45% of the requested RT-PCRs did not meet the criteria of the Ministry of Health, all of which were negative. The clinical characteristics of our patients differed slightly from those observed in other studies published in the general population, with cough and asthenia being the most frequent symptoms, present in 69.2% and 38.5%, respectively. 100% of the infected patients did not present complications that required assistance in the Intensive Care Unit. CONCLUSIONS: With the application of preventive and organizational actions, we consider that we have presented a low incidence of those infected. The preparation of protocols and their supervision is essential for the rapid identification of cases and optimization of the tests requested. Despite being a medium and long-stay hospital, we have not presented any mortality or complications that required admission to the Intensive Care Unit

A Vital Mediation: The Sanatorium, before and after Antibiotics.

As drug-resistant strains of tuberculosis spread across India, commentators have warned that we are returning to the sanatorium era. Such concerns might be symptomatically read in terms of loss; however, prophecies of return might also signal that there is something to be regained. Rather than lamenting the end of the antibiotic era, I shift the focus to ask about the sanatorium, not simply as a technology of the past, but as a technology of an imminent future. In examining late nineteenth- and early twentieth-century conversations about treating tuberculosis in India, I demonstrate how the the sanatorium was figured as a therapeutic technology that mediated the relationship between the body and its colonial milieu. In this light, I argue that contemporary prophecies of a future past register not simply the loss of antibiotic efficacy, but also a desire to return to a therapeutics that foregrounds issues of vitality, mediation, and environment.
