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.

Characteristics of Drug Resistant Tuberculosis in Sanatoria of North Korea.

Although several reports about drug-resistant tuberculosis (TB) in North Korea have been published, a nationwide surveillance on this disease remains to be performed. This study aims to analyze the drug resistance patterns of Mycobacterium tuberculosis among the patients in the sanatoria of North Korea, especially during the period when second-line drugs (SLDs) had not yet been officially supplied to this country. The Eugene Bell Foundation (EBF) transferred 947 sputum specimens obtained from 667 patients from 2007 to 2009 to the Clinical Research Center, Masan National Tuberculosis Hospital (MNTH), South Korea. Four hundred ninety-two patients were culture positive for TB (73.8%). Drug susceptibility test (DST) was performed for the bacilli isolated from 489 patients. Over 3 quarters of the cases (76.9%) were multidrug-resistant (MDR)-TB. Additionally, 2 patients had extremely drug-resistant (XDR)-TB. Very high resistance to first-line drugs and low resistance to fluoroquinolones (FQs) and injectable drugs (IDs) except for streptomycin (S) were detected. A small but significant regional variation in resistance pattern was observed. Big city regions had higher rate of MDR-TB, higher resistance to FQs and IDs than relatively isolated regions. In conclusion, significant number of drug-resistant TB was detected in North Korean sanatoria, and small but significant regional variations in resistance pattern were noticeable. However, the data in this study do not represent the nationwide drug resistance pattern in North Korea. Further large-scale evaluations are necessary to estimate the resistance pattern of TB in North Korea.

The implications of long-term acute care hospital transfer practices for measures of in-hospital mortality and length of stay.

RATIONALE: The National Quality Forum recently endorsed in-hospital mortality and intensive care unit length of stay (LOS) as quality indicators for patients in the intensive care unit. These measures may be affected by transferring patients to long-term acute care hospitals (LTACs). OBJECTIVES: To quantify the implications of LTAC transfer practices on variation in mortality index and LOS index for patients in academic medical centers. METHODS: We used a cross-sectional study design using data reported to the University HealthSystem Consortium from 2008-2009. Data were from patients who were mechanically ventilated for more than 96 hours. MEASUREMENTS AND MAIN RESULTS: Using linear regression, we measured the association between mortality index and LTAC transfer rate, with the hospital as the unit of analysis. Similar analyses were conducted for LOS index and cost index. A total of 137 hospitals were analyzed, averaging 534 transfers to LTAC per hospital during the study period. Mean±SD in-hospital mortality was 24±6.4%, and observed LOS was 30.4±8.2 days. The mean LTAC transfer rate was 15.7±13.7%. Linear regression demonstrated a significant correlation between transfer rate and mortality index (R2=0.14; P<0.0001) and LOS index (R2=0.43; P<0.0001). CONCLUSIONS: LTAC hospital transfer rate has a significant impact on reported mortality and LOS indices for patients requiring prolonged acute mechanical ventilation. This is an example of factors unrelated to quality of medical care or illness severity that must be considered when interpreting mortality and LOS as quality indicators.

[Prevalence and characteristics of the "burnout syndrome" of the medical staff of cancer and TB institutions of Primorskii Krai].

As 50 doctors and 70 nurses in oncologic dispensaries as well 90 doctors and 110 nurses in tuberculosis dispensaries in Primorye have been studied on the basis of voluntary testing methods supposed by C. Maslach and V.V. Boiko. The aim of this study was to estimate the relative prevalence and psychological features of the "burnout syndrome" among doctors and nurses of oncologic and tuberculosis dispensaries in Primorye Territory. "Emotional burnout" in various stages of its development is much more common among nurses (75% of respondents), compared with physicians (less than 50% tested). In nursing professional burnout syndrome developed significantly more frequently in the more severe form, and with less seniority of professional activity. The dependence of burning on the age and professional experience is more common for physicians. There is an urgent need to study the epidemiology of the "burnout syndrome" and identify ways to prevent the formation of social syndrome in medical personnel.

A retrospective study of seasonal variation in the number of cases diagnosed at a tertiary care tuberculosis hospital.

OBJECTIVE: To study the seasonality of tuberculosis (TB) in a tertiary care tuberculosis and respiratory hospital in Delhi. METHODS: Data from a tertiary care respiratory hospital in south Delhi over a six years period from April 2002 to March 2008 were analysed. RESULTS: Symptomatics: A total of 192,863 patients were registered newly in the hospital during this period. Maximum number of symptomatic patients reported to the out-patient department during April-June and the minimum during October-December. An increase of about 25% in symptomatics was observed (p < 0.05) in the period from April to June in comparison to October to December. The amplitude of seasonal variation was estimated as 11% of the annual mean symptomatics. Tuberculosis cases: The maximum sputum-positive TB cases were diagnosed during the period from April to June and the number was least during October to December. There was an increase of about 34% in sputum-positive cases (p < 0.001) during the period from April to June against October to December. The amplitude of seasonal variation was estimated as 14.4% of the annual mean smear-positives per quarter. The extra-pulmonary TB (EPTB) cases were the maximum during April-June. Chest symptomatics of all types of TB cases were the lowest in January. CONCLUSIONS: A seasonal pattern of TB was observed for pulmonary TB and EPTB cases. This information would be useful for administration and managers to take extra care to arrange and provide extra facilities during the peak seasons.

[Periodicity and quality of clinical diagnostics of protracted pneumonia in a tuberculosis clinic].

Analysis of the quality and modes of clinical diagnostics of protracted pneumonia in a tuberculosis clinic revealed the most frequent causes of this condition responsible for hyperdiagnostics of tuberculosis. These are concomitant diseases, pneumosclerosis, chronic bronchitis, fibrous transformation of the bronchial tree, complicated clinical course of pneumonia, age above 60 years, history of tuberculosis, inadequate or short-term antibiotic therapy at the initial stages of diagnostics. Motivational prerequisites for high-quality diagnostic work include compliance with standards and guidelines for the examination and management of patients suspected of having pneumonia with a view to detecting tuberculosis. Such approach would decrease the frequency of ungrounded hospitalization of patients at tuberculosis clinics.

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.

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.

Antituberculosis drug prescribing for inpatients in a national tuberculosis hospital in China, 2011-2015.

OBJECTIVES: This study aimed to describe trends in antituberculosis drug prescribing for inpatients from 2011-2015 in a Chinese national tuberculosis (TB) hospital. METHODS: This retrospective study, performed in March 2016, reviewed the medical records of all inpatients from Beijing Chest Hospital diagnosed with TB between 2011-2015. Medication used for TB treatment during the inpatient period was recorded. RESULTS: A total of 11465 inpatients were enrolled in the study. The most frequently prescribed drug for inpatients was isoniazid (71.2%; 8164/11465), followed by ethambutol (67.5%; 7738/11465), pyrazinamide (59.7%; 6839/11465) and rifampicin (40.0%; 4589/11465). In addition, amikacin (16.5%; 1889/11465), levofloxacin (33.0%; 3789/11465), para-aminosalicylic acid (12.4%; 1422/11465) and clarithromycin (3.5%; 406/11465) were the most common drugs used in the treatment of inpatients for Group II, III, IV and V drugs, respectively. A significant increasing trend in prescribing was found for rifampicin, pyrazinamide, capreomycin, moxifloxacin, prothionamide, para-aminosalicylic acid, cycloserine, clofazimine and linezolid, respectively, whilst there was a significant decreasing trend in the rate of prescribing of ethambutol, amikacin, levofloxacin, amoxicillin/clavulanic acid and clarithromycin during the 5-year study period (Ptrend<0.01). CONCLUSIONS: These data demonstrate that prescription of anti-TB drugs varied greatly across clinical diagnostic categories, treatment history and drug susceptibility profiles of TB patients. The World Health Organization (WHO)-endorsed standard regimen should be more extensively employed under conditions where drug susceptibility testing is unavailable in order to guide clinicians to formulate a suitable treatment regimen for TB patients.

Use of low-dose computed tomography to assess pulmonary tuberculosis among healthcare workers in a tuberculosis hospital.

BACKGROUND: According to the World Health Organization, China is one of 22 countries with serious tuberculosis (TB) infections and one of the 27 countries with serious multidrug-resistant TB strains. Despite the decline of tuberculosis in the overall population, healthcare workers (HCWs) are still at a high risk of infection. Compared with high-income countries, the TB prevalence among HCWs is higher in low- and middle-income countries. Low-dose computed tomography (LDCT) is becoming more popular due to its superior sensitivity and lower radiation dose. However, there have been no reports about active pulmonary tuberculosis (PTB) among HCWs as assessed with LDCT. The purposes of this study were to examine PTB statuses in HCWs in hospitals specializing in TB treatment and explore the significance of the application of LDCT to these workers. METHODS: This study retrospectively analysed the physical examination data of healthcare workers in the Beijing Chest Hospital from September 2012 to December 2015. Low-dose lung CT examinations were performed in all cases. The comparisons between active and inactive PTB according to the CT findings were made using the Pearson chi-square test or the Fisher's exact test. Comparisons between the incidences of active PTB in high-risk areas and non-high-risk areas were performed using the Pearson chi-square test. Analyses of active PTB were performed according to different ages, numbers of years on the job, and the risks of the working areas. Active PTB as diagnosed by the LDCT examinations alone was compared with the final comprehensive diagnoses, and the sensitivity and positive predictive value were calculated. RESULTS: A total of 1 012 participants were included in this study. During the 4-year period of medical examinations, active PTB was found in 19 cases, and inactive PTB was found in 109 cases. The prevalence of active PTB in the participants was 1.24%, 0.67%, 0.81%, and 0.53% for years 2012 to 2015. The corresponding incidences of active PTB among the tuberculosis hospital participants were 0.86%, 0.41%, 0.54%, and 0.26%. Most HCWs with active TB (78.9%, 15/19) worked in the high-risk areas of the hospital. There was a significant difference in the incidences of active PTB between the HCWs who worked in the high-risk and non-high-risk areas (odds ratio [OR], 14.415; 95% confidence interval (CI): 4.733 - 43.896). Comparisons of the CT signs between the active and inactive groups via chi-square tests revealed that the tree-in-bud, cavity, fibrous shadow, and calcification signs exhibited significant differences (P = 0.000, 0.021, 0.001, and 0.024, respectively). Tree-in-bud and cavity opacities suggest active pulmonary tuberculosis, whereas fibrous shadow and calcification opacities are the main features of inactive pulmonary tuberculosis. Comparison with the final comprehensive diagnoses revealed that the sensitivity and positive predictive value of the diagnoses of active PTB based on LDCT alone were 100% and 86.4%, respectively. CONCLUSIONS: Healthcare workers in tuberculosis hospitals are a high-risk group for active PTB. Yearly LDCT examinations of such high-risk groups are feasible and necessary.

[Anti-nicotine education applied in relation of parents of the diseased children on chronic allergic diseases of respiratory system]. / Edukacja antynikotynowa stosowana wobec rodziców dzieci chorych na przewlekle alergiczne choroby ukladu oddechowego.

The allergies of respiratory system are at children the frequent illnesses. Among favorable them factors, risk on passive smoking tobacco can be also. Passive smoking is defined as risk non-smoking on tobacco smoke in environment. Recent reports represent that smoking in home environment tobacco increase on passive smokers' asthma morbidity, especially children in school age. It in it was report the necessity of leadership of anti-nicotine education was underlined in the face of smoking parents. It bets that she should motivate she better parents to cessation smoking, using authority of doctor and love parental. Acting we decided with these principles to analyze effectiveness two year anti-nicotine education which be applied in the face of all treated smoking parents of children with reason of chronic allergic diseases of respiratory system in out-patients. The study comprised parents of 146 children at the Allergy out-Patients clinic, who were diagnosed and cured in years 2003-2005. Generally were 292 persons. The children be treated with reason of bronchial asthma and allergic rhinitis. It the data on subject of smoking of tobacco were collected was on basis of interview got from parents during visits at information bureau on beginning the treatment the children, in his track as well as after two years of education. The anti-nicotine education was applied by whole period of observation during routine medical visits. In moment beginning of treatment in studied group the parents' and education children (n = 292) it 79 the parents' couple did not smoke. Smoking parents among remaining 67 steams were. From among them parents 13 children smoked both, only father in 36 cases smoked and mother in remaining 18 parents' couple smoked. 80 parents smoked with generally. 63 persons after two years of anti-nicotine education the nonsmoking committed one from group smoking. 22 persons among them were from among 24 fathers and 17 mothers' peer in which smoked both parents. Remaining smoking and non-smoking parents granted that children tried to restrain to minimum stay in environment smoking. We on basis of received results to affirm that child's disease has on parents' behaviour essential influence can. It in child was affirmed was all analyzed situations characteristic decrease number with diseased child of smokers' families. Recapitulating anti-nicotine education of the children's parents diseased on chronic allergic diseases of respiratory system is very good restrictive agent their exposition on smoking the tobacco. Contemporaneously in effective way influences on decisions of adults about cessation smoking and the healthy style of life promotes.

[Organization of hospital care to patients with tuberculosis concurrent with HIV infection in Tuberculosis care hospital No. seven].

HIV-infection morbidity rates continue to increase in Moscow, the Moscow Region, and in the whole country. The epidemiological situation associated with tuberculosis concurrent with HIV infection remains tense in Moscow and its region, as judged from the data of an analysis of this disease at tuberculosis hospital seven (TH-7) over 9 years. A total of 411 patients with tuberculosis concurrent with HIV infection were treated at TH-7 in 1996 to December 2004. Among them, 49.6% were Moscow residents, 15.1 and 26.5% of the patients lived in the Moscow Region and other regions of the Russian Federation, respectively; 6.8% were homeless persons and 2% foreigners. The number of patients with tuberculosis concurrent with HIV infection has been annually increasing at TH-7. Among the total number of patients, their proportion was 13.4% in 2004. In the structure of patients with comorbidity, the proportion of surgical patients has been on the rise and it was 51.8% in 2004. Among the surgical patients with tuberculosis concurrent with HIV, the proportion of patients with generalized (multiple organ) tuberculosis has increased; it was 50% in 2004. Patients with tuberculosis concurrent with HIV infection need a greater scope of surgical interventions al number of patients for therapeutic and diagnostic purposes.

[Survey of hemodialysis inpatients in long-term care facilities].

OBJECTIVE: In Japan, the number of elderly patients on hemodialysis has markedly increased in recent years. We conducted a survey to confirm the current status of inpatient hemodialysis patients and dialysis facilities with the aim of providing better care. MATERIAL AND METHODS: The subjects were 57 dialysis patients admitted to the Jishu Hospital for three consecutive months or longer as of February 2004. The survey was conducted by obtaining informed-consent from the patients and their families. The patients were interviewed and a questionnaire was sent to their families. The survey items were as follows; 1) patient characteristics, 2) domestic status, 3) physical and mental condition and 4) awareness concerning the hospital. RESULTS: The survey showed that dementia is present in almost all elderly hemodialysis patients and they require some degree of assistance for the activities of daily living. In addition, 57.9% patients had already been admitted to or had visited two or more hospitals. The current status of inpatients had improved slightly. Although the period of hospitalization was longer than one year in 64.9% of respondents, it had decreased by around 13% in comparison with that in the previous survey at 1997. These results were considered to be caused by increases in inpatient dialysis facilities, aging-related deaths, and by patients switching to home care after discharge because of the higher economic burden. In the interview, some patients were satisfied with inpatient life, but about one half of the patients said they wanted home care. Key caregivers for patients are mainly middle-aged or older family members (> 50 years old), indicating that caregivers are aging. On the other hand, the present study showed that hospitalization provides advantages for family life, such as improvements in peace of mind, life rhythm, leisure time and physical condition. CONCLUSION: Since the aging of dialysis patients results in a decrease in physical activity and progression of dementia, long-term hospitalization has a high potential to induce bedridden patients. In addition to the requirement for more long-term facilities, efforts should be made to improve physical activities and inhibit the progression of dementia.

Methicillin-resistant Staphylococcus aureus in geriatric patients: usefulness of screening in a chronic-care setting.

OBJECTIVE: To evaluate the contribution of screening to the detection of cases of methicillin-resistant Staphylococcus aureus (MRSA) in a chronic-care facility. DESIGN: Surveillance and laboratory observational study. METHODS: During a 7-month period, we compared imported and acquired MRSA in a chronic-care center by screening patients for carriage of MRSA on admission and discharge, and by recording all cases of clinical specimens positive for MRSA. SETTING: The study was conducted in a 120-bed chronic-care center. This center admits approximately 850 patients per year. Approximately 90% of the patients were elderly and were admitted from other hospitals. RESULTS: Of 519 patients admitted during the study period, 129 were positive for MRSA at some point during their residence, including 60 (11.6%) with MRSA found within 48 hours of admission and 69 (13.3%; 53% of all positives) with nosocomial MRSA Of the 519 admissions, 332 (64%) were discharged, of whom 62 (19%) were positive for MRSA Of these 62, 43 (69%) acquired their MRSA during their stay in the center. CONCLUSIONS: Our study confirms the amplification effect of chronic-care facilities on MRSA propagation. It also shows that screening for MRSA carriage in a chronic-care center facilitates the early identification of a large proportion of patients with MRSA.

An epidemiologic study of nosocomial infections in a pediatric long-term care facility.

OBJECTIVE: To determine the incidence of hospital-acquired (nosocomial) infection in pediatric long-term care facilities. DESIGN: Prospective cohort. SETTING: An 87-bed pediatric long-term care facility. PATIENTS: All patients receiving long-term care at Bloorview Children's Hospital during the study period. RESULTS: Infection developed in 40.1% of patients (n = 456). The nosocomial infection rate per 1000 patient days (mean, 7.84) varied substantially, from 1.66 in May 1988 to 16.37 day in April, 1989. The proportional frequencies of infections were as follows: respiratory, 41.6% (37.0% upper, 4.6% lower); urinary tract, 31.0%; skin, 15.6% (gastric tube site 5.0%, other 10.6%), eyes, 6.4%; gastrointestinal, 3.5%; and other, 1.5%. Of those infections for which an organism was recovered (48.5%), pathogens included Escherichia coli (22.5%), Enterococcus (14.8%), Staphylococcus (14.8%), Streptococcus (11.2%), Klebsiella (10.5%), Pseudomonas (10.1%), Proteus (4.3%), yeast (4.3%), Salmonella (0.7%), Clostridium difficile (0.4%), and other (6.2%). CONCLUSIONS: The incidence and nature of infections in pediatric long-term care facilities differs from those in acute care facilities. Physicians should become familiar with the infection rates in the populations whom they treat. Control requires compliance with currently recognized effective strategies as well as innovative practical approaches to respiratory disease. Behavioral problems related to frequent clean, intermittent catheterization in young adults need to be addressed.

Amyotrophic lateral sclerosis care in Italy: a nationwide study in neurological centers.

Recently, formal standards for the management of amyotrophic lateral sclerosis (ALS) have been proposed by the American Academy of Neurology (AAN). However, there are few information about the actual care of ALS. We have assessed the management of ALS in Italy in various clinical settings, on basis of a self-reported questionnaire. Thirty-six out of the 80 Italian ALS neurological departments with a particular interest in ALS care answered the questionnaire. The centers were subdivided according the mean number of patients currently followed-up (> or =30 vs. <30). An integrated health-care team for ALS existed in all large centers but only in 14% of small centers (p=0.0001). Diagnosis was communicated to most but not all patients. Symptomatic therapies were generally offered to patients in all centers. Nutritional interventions, including percutaneous endoscopic gastrostomy (PEG), were proposed by most centers, but the percentage of patients who underwent PEG was significantly higher in large centers (p=0.04). Respiratory management seemed to be lacking both in large and in small centers since non-invasive positive pressure ventilation (NIPPV) was proposed by only 70% of large and 50% of small centers; however, the percentage of patients who underwent NIPPV was significantly higher in large centers (p=0.03). Moreover, the discussion of respiratory issues was performed quite late in the course of the disease, usually when the patients have first respiratory symptoms. Therefore, there are considerable opportunities to improve the care of ALS patients in Italy, primarily through the education of neurologists on AAN standards of care for ALS.

Inst-Risk II: an approach to forecasting relative risk of future institutional placement.

This article describes a model development process that represents a useful step in classifying populations in terms of risk of institutionalization (Inst-Risk II). A four-category risk classification system--"High risk, Some risk, Low risk, and Very Low Risk"--was developed, based on combinations of measures of functional status, age, health status, demographics, and social supports. Our review of variables found by other researchers to be related to high risk of institutional placement, as well as our own research with Massachusetts elderly, confirmed functional impairment, diagnostic conditions, and advanced age to be major predictors of institutional placement. At the other extreme, Very Low risk status was indicated by combinations of functional independence, absence of health problems, and relatively younger age. Using baseline data of the kind that can be easily gathered and are often obtained in social agency screening interviews, our research indicates that this instrument differentiates among these risk status groups for two- to four-year periods.
