RESUMO

BACKGROUND: Risk factors for nontuberculous mycobacteria (NTM) infections after solid organ transplant (SOT) are not well characterized. Here we aimed to describe these factors. METHODS: Retrospective, multinational, 1:2 matched case-control study that included SOT recipients ≥12 years old diagnosed with NTM infection from 1 January 2008 to 31 December 2018. Controls were matched on transplanted organ, NTM treatment center, and post-transplant survival greater than or equal to the time to NTM diagnosis. Logistic regression on matched pairs was used to assess associations between risk factors and NTM infections. RESULTS: Analyses included 85 cases and 169 controls (59% male, 88% White, median age at time of SOT of 54 years [interquartile range {IQR} 40-62]). NTM infection occurred in kidney (42%), lung (35%), heart and liver (11% each), and pancreas transplant recipients (1%). Median time from transplant to infection was 21.6 months (IQR 5.3-55.2). Most underlying comorbidities were evenly distributed between groups; however, cases were older at the time of NTM diagnosis, more frequently on systemic corticosteroids and had a lower lymphocyte count (all P < .05). In the multivariable model, older age at transplant (adjusted odds ratio [aOR] 1.04; 95 confidence interval [CI], 1.01-1.07), hospital admission within 90 days (aOR, 3.14; 95% CI, 1.41-6.98), receipt of antifungals (aOR, 5.35; 95% CI, 1.7-16.91), and lymphocyte-specific antibodies (aOR, 7.73; 95% CI, 1.07-56.14), were associated with NTM infection. CONCLUSIONS: Risk of NTM infection in SOT recipients was associated with older age at SOT, prior hospital admission, receipt of antifungals or lymphocyte-specific antibodies. NTM infection should be considered in SOT patients with these risk factors.

RESUMO

Nontuberculous mycobacteria (NTM) infections are caused by environmental exposure. We describe spatial distribution of NTM infections and associations with sociodemographic factors and flooding in Missouri, USA. Our retrospective analysis of mycobacterial cultures reported to the Missouri Department of Health and Social Services surveillance system during January 1, 2008-December 31, 2019, detected geographic clusters of infection. Multilevel Poisson regression quantified small-area geographic variations and identified characteristics associated with risk for infection. Median county-level NTM infection rate was 66.33 (interquartile range 51-91)/100,000 persons. Risk of clustering was significantly higher in rural areas (rate ratio 2.82, 95% CI 1.90-4.19) and in counties with >5 floodings per year versus no flooding (rate ratio 1.38, 95% CI 1.26-1.52). Higher risk for NTM infection was associated with older age, rurality, and more flooding. Clinicians and public health professionals should be aware of increased risk for NTM infections, especially in similar environments.

RESUMO

BACKGROUND: Though work has been done studying nursing home (NH) residents with either advanced Alzheimer's disease (AD) or Alzheimer's disease related dementia (ADRD), none have distinguished between them; even though their clinical features affecting survival are different. In this study, we compared mortality risk factors and survival between NH residents with advanced AD and those with advanced ADRD. METHODS: This is a retrospective observational study, in which we examined a sample of 34,493 U.S. NH residents aged 65 and over in the Minimum Data Set (2011-2013). Incident assessment of advanced disease was defined as the first MDS assessment with severe cognitive impairment (Cognitive Functional Score equals to 4) and diagnoses of AD or ADRD. Demographics, functional limitations, and comorbidities were evaluated as mortality risk factors using Cox models. Survival was characterized with Kaplan-Maier functions. RESULTS: Of those with advanced cognitive impairment, 35 % had AD and 65 % ADRD. At the incident assessment of advanced disease, those with AD had better health compared to those with ADRD. Mortality risk factors were similar between groups (shortness of breath, difficulties eating, substantial weight-loss, diabetes mellitus, heart failure, chronic obstructive pulmonary disease, and pneumonia; all p < 0.01). However, stroke and difficulty with transfer (for women) were significant mortality risk factors only for those with advanced AD. Urinary tract infection, and hypertension (for women) only were mortality risk factors for those with advanced ADRD. Median survival was significantly shorter for the advanced ADRD group (194 days) compared to the advanced AD group (300 days). CONCLUSIONS: There were distinct mortality and survival patterns of NH residents with advanced AD and ADRD. This may help with care planning decisions regarding therapeutic and palliative care.

RESUMO

BACKGROUND: Infections are common occurrences at end of life that are associated with high rates of morbidity and mortality among frail elderly individuals. The problem of infections in nursing homes has led to a subsequent overuse and misuse of antibiotics in this already-frail population. Improving palliative care in nursing homes has been proposed as a key strategy to reduce the use of antibiotics. AIM: The aim of this study was to describe the current status of how nursing homes integrates palliative care and infection management at end of life across the nation. DESIGN: This is a cross-sectional survey of nationally representative US nursing homes. SETTING/PARTICIPANTS: Between November 2017 and October 2018, a survey was conducted with a nationally representative random sample of nursing homes and 892 surveys were completed (49% response rate). The weighted study sample represented 15,381 nursing homes across the nation. RESULTS: Most nursing homes engaged in care plan documentation on what is important to residents (90.43%) and discussed spiritual needs of terminally ill residents (89.50%). In the event of aspiration pneumonia in terminally ill residents, 59.43% of nursing homes responded that resident would be transferred to the hospital. In suspected urinary tract infection among terminally ill residents, 66.62% of nursing homes responded that the resident will be treated with antibiotics. CONCLUSION: The study found wide variations in nursing home palliative care practices, particularly for timing of end-of-life care discussions, and suboptimal care reported for antibiotic usage. Further education for nursing home staff on appropriate antibiotic usage and best practices to integrate infection management in palliative care at the end of life is needed.

RESUMO

Recently, the Centers for Medicare & Medicaid Services (CMS) final rule required that nursing homes (NHs) develop an infection control program that includes an antibiotic stewardship component and employs a trained infection preventionist (IP). The objectives of this study were to provide a baseline assessment of (1) NH facility and infection control program characteristics associated with having an infection control deficiency citation and (2) associations between IP training and the presence of antibiotic stewardship policies, controlling for NH characteristics. A cross-sectional survey of 2514 randomly sampled US NHs was conducted to assess IP training, staff turnover, and infection control program characteristics (ie, frequency of infection control committee meetings and the presence of 7 antibiotic stewardship policies). Responses were linked to concurrent Certification and Survey Provider Enhanced Reporting data, which contain information about NH facility characteristics and citations. Descriptive statistics and multivariable regression analyses were conducted to account for NH characteristics. Surveys were received from 990 NHs; 922 had complete data. One-third of NHs in this sample received an infection control deficiency citation. The NHs that received deficiency citations were more likely to have committees that met weekly/monthly versus quarterly ( P < .01). The IPs in 39% of facilities had received specialized training. Less than 3% of trained IPs were certified in infection control. The NHs with trained IPs were more likely to have 5 of the 7 components of antibiotic stewardship in place (all P < .05). The IP training, although infrequent, was associated with the presence of antibiotic stewardship policies. Receiving an infection control citation was associated with more frequent infection control committee meetings. Training and support of IPs is needed to ensure infection control and antibiotic stewardship in NHs. As the CMS rule becomes implemented, more research is warranted. There is a need for increase in trained IPs in US NHs. These data can be used to evaluate the effectiveness of the CMS final rule on infection management processes in US NHs.

RESUMO

BACKGROUND: The prevalence of depression among drug users is high. It has been recognized that drug use behaviors can be influenced and spread through social networks. OBJECTIVES: We investigated the directional relationship between social network factors and depressive symptoms among a sample of inner-city residents in Baltimore, MD. METHODS: We performed a longitudinal study of four-wave data collected from a network-based HIV/STI prevention intervention for women and network members, consisting of both men and women. Our primary outcome and exposure were depression using CESD scale and social network characteristics, respectively. Linear-mixed model with clustering adjustment was used to account for both repeated measurement and network design. RESULTS: Of the 746 participants, those who had high levels of depression tended to be female, less educated, homeless, smokers, and did not have a main partner. In the univariate longitudinal model, larger size of drug network was significantly associated with depression (OR = 1.38, p < .001). This relationship held after controlling for age, gender, homeless in the past 6 months, college education, having a main partner, cigarette smoking, perceived health, and social support network (aOR = 1.19, p = .001). In the univariate mixed model using depression to predict size of drug network, the data suggested that depression was associated with larger size of drug network (coef. = 1.23, p < .001) and the same relation held in multivariate model (adjusted coef. = 1.08, p = .001). CONCLUSIONS: The results suggest that larger size of drug network is a risk factor for depression, and vice versa. Further intervention strategies to reduce depression should address social networks factors.

RESUMO

Background: Fixed, large volume resuscitation with intravenous fluids (IVFs) in septic shock can cause inadvertent hypervolemia, increased medical interventions, and death when unguided by point-of-care ultrasound (POCUS). The primary study objective was to evaluate whether total IVF volume differs for emergency department (ED) septic shock patients receiving POCUS versus no POCUS. Methods: We conducted a retrospective observational cohort study from 7/1/2018 to 8/31/2021 of atraumatic adult ED patients with septic shock. We agreed upon a priori variables and defined septic shock as lactate ≥4 and hypotension (SBP <90 or MAP <65). A sample size of 300 patients would provide 85% power to detect an IVF difference of 500 milliliters between POCUS and non-POCUS cohorts. Data are reported as frequencies, median (IQR), and associations from bivariate logistic models. Results: 304 patients met criteria and 26% (78/304) underwent POCUS. Cardiac POCUS demonstrated reduced ejection fraction in 15.4% of patients. Lung ultrasound showed normal findings in 53% of patients. The POCUS vs. non-POCUS cohorts had statistically significant differences for the following variables: higher median lactate (6.7 [IQR 5.2-8.7] vs. 5.6], p = 0.003), lower systolic blood pressure (77.5 [IQR 61-86] vs. 85.0, p < 0.001), more vasopressor use (51% vs. 34%, p = 0.006), and more positive pressure ventilation (38% vs. 24%, p = 0.017). However, there were no statistically significant differences between POCUS and non-POCUS cohorts in total IVF volume ml/kg (33.02 vs. 32.1, p = 0.47), new oxygen requirement (68% vs. 59%, p = 0.16), ED death (3% vs. 4%, p = 0.15), or hospital death (31% vs. 27%, p = 0.48). There were similar distributions of lactate, total fluids, and vasopressors in patients with CHF and severe renal failure. Conclusions: Among ED patients with septic shock, POCUS was more likely to be used in sicker patients. Patients who had POCUS were given similar volume of crystalloids although these patients were more critically ill. There were no differences in new oxygen requirement or mortality in the POCUS group compared to the non-POCUS group.

RESUMO

BACKGROUND: Despite increasing morbidity and mortality from non-communicable diseases (NCD) globally, health systems in low- and middle-income countries (LMICs) have limited capacity to address these chronic conditions, particularly in sub-Saharan Africa (SSA). There is an urgent need, therefore, to respond to NCDs in SSA, beginning by applying lessons learned from the first global response to any chronic disease-HIV-to tackle the leading cardiometabolic killers of people living with HIV (PLHIV). We have developed a feasible and acceptable package of evidence-based interventions and a multi-faceted implementation strategy, known as "TASKPEN," that has been adapted to the Zambian setting to address hypertension, diabetes, and dyslipidemia. The TASKPEN multifaceted implementation strategy focuses on reorganizing service delivery for integrated HIV-NCD care and features task-shifting, practice facilitation, and leveraging HIV platforms for NCD care. We propose a hybrid type II effectiveness-implementation stepped-wedge cluster randomized trial to evaluate the effects of TASKPEN on clinical and implementation outcomes, including dual control of HIV and cardiometabolic NCDs, as well as quality of life, intervention reach, and cost-effectiveness. METHODS: The trial will be conducted in 12 urban health facilities in Lusaka, Zambia over a 30-month period. Clinical outcomes will be assessed via surveys with PLHIV accessing routine HIV services, and a prospective cohort of PLHIV with cardiometabolic comorbidities nested within the larger trial. We will also collect data using mixed methods, including in-depth interviews, questionnaires, focus group discussions, and structured observations, and estimate cost-effectiveness through time-and-motion studies and other costing methods, to understand implementation outcomes according to Proctor's Outcomes for Implementation Research, the Consolidated Framework for Implementation Research, and selected dimensions of RE-AIM. DISCUSSION: Findings from this study will be used to make discrete, actionable, and context-specific recommendations in Zambia and the region for integrating cardiometabolic NCD care into national HIV treatment programs. While the TASKPEN study focuses on cardiometabolic NCDs in PLHIV, the multifaceted implementation strategy studied will be relevant to other NCDs and to people without HIV. It is expected that the trial will generate new insights that enable delivery of high-quality integrated HIV-NCD care, which may improve cardiovascular morbidity and viral suppression for PLHIV in SSA. This study was registered at ClinicalTrials.gov (NCT05950919).

RESUMO

BACKGROUND: Preliminary evidence suggests that digital mental health intervention (Wysa for Chronic Pain) can improve mental and physical health in people with chronic musculoskeletal pain and coexisting symptoms of depression or anxiety. However, the behavioral mechanisms through which this intervention acts are not fully understood. OBJECTIVE: The purpose of this study was to identify behavioral mechanisms that may mediate changes in mental and physical health associated with use of Wysa for Chronic Pain during orthopedic management of chronic musculoskeletal pain. We hypothesized that improved behavioral activation, pain acceptance, and sleep quality mediate improvements in self-reported mental and physical health. METHODS: In this prospective cohort, pilot mediation analysis, adults with chronic (≥3 months) neck or back pain received the Wysa for Chronic Pain digital intervention, which uses a conversational agent and text-based access to human counselors to deliver cognitive behavioral therapy and related therapeutic content. Patient-reported outcomes and proposed mediators were collected at baseline and 1 month. The exposure of interest was participants' engagement (ie, total interactions) with the digital intervention. Proposed mediators were assessed using the Behavioral Activation for Depression Scale-Short Form, Chronic Pain Acceptance Questionnaire, and Athens Insomnia Scale. Outcomes included Patient-Reported Outcomes Measurement Information System Anxiety, Depression, Pain Interference, and Physical Function scores. A mediation analysis was conducted using the Baron and Kenny method, adjusting for age, sex, and baseline mediators and outcome values. P<.20 was considered significant for this pilot study. RESULTS: Among 30 patients (mean age 59, SD 14, years; 21 [70%] female), the mediation effect of behavioral activation on the relationship between increased intervention engagement and improved anxiety symptoms met predefined statistical significance thresholds (indirect effect -0.4, 80% CI -0.7 to -0.1; P=.13, 45% of the total effect). The direction of mediation effect was generally consistent with our hypothesis for all other proposed mediator or outcome relationships, as well. CONCLUSIONS: In a full-sized randomized controlled trial of patients with chronic musculoskeletal pain, behavioral activation, pain acceptance, and sleep quality may play an important role in mediating the relationship between use of a digital mental health intervention (Wysa for Chronic Pain) and improved mental and physical health.

RESUMO

In India, oral cancers are the major cause of cancer-related death. Tongue and buccal mucosa being the major subsites in oral cancer have varying clinicopathological presentations. This study is intended to know the difference in clinicopathological behavior of these two subsites. This retrospective study included 474 patients of which 232 patients had tongue cancer and 242 patients had buccal alveolar complex (BAC) cancer. Comparison between the pathological characters including pattern of nodal involvement was analyzed. Disease-free survival (DFS) and factors influencing the DFS were analyzed and compared using Cox regression analysis. Mean age of the study population was 52.7 years. Tongue oral squamous cell carcinoma (OSCC) differed significantly from BAC OSCC in terms of age of presentation, tumor staging, and perineural invasion. Among neck nodal involvement, tongue OSCC commonly involved level IIa (p < 0.001) whereas BAC involved level Ib (p < 0.001). At a median follow-up of 27 months, 141 patients had disease recurrence, tongue OSCC commonly recurred in neck (p = 0.008), and BAC OSCC relapsed at primary site (p = 0.001). Patients older than 45 years with BAC cancer had lesser risk of recurrence (HR, 0.30; 95% CI, 0.2-0.5; p < 0.0001). Pathological tumor stage in tongue cancer (HR, 14.9; 95% CI, 2.6-84.8; p = 0.002) and grade of tumor differentiation in BAC OSCC (HR, 9.2; 95% CI, 1.9-43.3; p < 0.005) were the most significant factors that influenced tumor recurrence. There was a significant difference in factors influencing disease recurrence among tongue and BAC OSCC. Also, pattern of nodal metastasis and pattern of recurrence were different. Hence, further research on OSCC may be done site specific. Supplementary Information: The online version contains supplementary material available at 10.1007/s13193-023-01750-8.

RESUMO

BACKGROUND: Oral squamous cell carcinoma (OSCC) remains the most common cancer among Indian men. OSCC involving the tongue and bucco alveolar complex (BAC) behaves differently. Nevertheless, the differences in clinical features and symptoms between the two subsites and their relation to pathology remain largely unexplored. STUDY DESIGN: The study compared various clinical parameters and pathological factors between tongue cancer patients and patients with BAC cancer. RESULTS: Among 474 patients, 232 had tongue cancer and 242 had BAC cancer. Except for the ulcer, 30% of patients with OSCC were asymptomatic at presentation. Compared to tongue cancers, lesions confined to BAC present at an advanced stage (P = 0.006). Multivariate analysis showed that dysphagia in tongue cancer (P = 0.020) and external swelling or lesion in BAC cancers (P = 0.002) were significant predictors of an advanced stage of the disease. On histopathology, perineural invasion (PNI) was significantly associated with tongue (P = 0.008) compared to BAC cancers (P = 0.015). Cancers of the tongue with pain and referred otalgia had a significantly higher depth of invasion (DOI), compared to those without pain (DOI - no pain 6.9 mm, pain 9.9 mm, and referred otalgia 11.4 mm). CONCLUSIONS: Patients with OSCC present late and in an advanced stage of the disease. Among tongue cancers, clinical history of pain was significantly associated with DOI and PNI, the significance of which needs to be prospectively analyzed. Clinical history in OSCC can be used as predicting factor for an advanced pathological stage of the disease. It also had an influence on various pathological characters, which is subsite specific.

RESUMO

Although Worst pattern of invasion (WPOI) is one of the histopathological (HP) markers that has been utilized in risk stratification of oral squamous cell carcinoma (OSCC) patients, its potential as an independent predictive factor for lymph node metastasis (LNM) and prognosis is least analyzed. Aim of the study is to analyze the relationship of various HP parameters to WPOI, their propensity for lymph node metastasis and prognostic value. This retrospective study included 140 patients diagnosed with resectable OSCC who underwent definitive surgery. Multiparametric HP risk assessment was done on the postoperative specimen and patients were categorized as low-risk WPOI (Type 1-3), and high-risk group (type 4 and 5). After categorization, 36.1% patients had low-risk WPOI and 63.9% had high-risk WPOI. Significant association was noted between WPOI and patient's age (p = 0.001), nodal stage (p = 0.001), lymphovascular invasion (LVI) (p = 0.006) and neural invasion (p = 0.001). 87% patients with nodal metastasis had high risk WPOI. LVI (p = 0.014) and WPOI (p < 0.001) had significant predictive role in LNM. High-risk WPOI and bone involvement were found to be predictive factors for overall survival, and only high risk WPOI had strong correlation with disease free survival having significant poor prognosis. Analyzing WPOI is essential in reporting HP specimens in OSCC. High-risk WPOI can act as an independent predictor for LNM, early recurrence and poor prognosis. Incorporation of WPOI into TNM staging is recommended to improve clinician's ability to prognosticate and individualize treatment strategies.

RESUMO

BACKGROUND: Integrase inhibitors (INSTIs) have been associated with poorer cognition in people with HIV (PWH). We examined the impact of switching to INSTIs on neuropsychological (NP) outcomes in PWH 40 years of age and older. METHODS: From the AIDS Clinical Trials Group observational cohort study, HAILO, we identified PWH who switched to INSTIs, had ≥2 NP assessments before and at least 1 after switch, and maintained viral suppression while on INSTIs. NP performance was assessed with a composite score (NPZ4) including Hopkins Verbal Learning Test (HVLT-R), Digit Symbol test (DSY), Trail Making A, and Trail Making B, while adjusting for covariates and learning effects. Outcomes changes from preswitch and postswitch periods were estimated using piecewise linear mixed models. RESULTS: Among 395 PWH (mean age 54 years, 81% male, 20% Hispanic, and 29% Black) NPZ4 increased preswitch and postswitch. There was no difference in slopes between periods for NPZ4 [preswitch 0.036/year (95% CI: 0.03 to 0.043); postswitch 0.022/year (95% CI: 0.006 to 0.005); P = 0.147]. All tests scores improved preswitch (P < 0.01). Postswitch, Trail Making A and DSY increased (all P < 0.01) without differences in rate of change (all P > 0.05). HVLT-R had a nonsignificant decrease postswitch (P = 0.22), resulting in a significant preswitch vs postswitch difference in slopes (P = 0.03). CONCLUSIONS: NP performance improved regardless of INSTI use. There was an attenuation of improvement in verbal memory in the postswitch vs preswitch period. The clinical significance of these changes is unclear but, overall, INSTIs did not have a consistent detrimental effect on NP outcomes.

RESUMO

Mycobacterium tuberculosis (M. tuberculosis) causes an enormous burden of disease worldwide. As a central aspect of its pathogenesis, M. tuberculosis grows in macrophages, and host and microbe influence each other's metabolism. To define the metabolic impact of M. tuberculosis infection, we performed global metabolic profiling of M. tuberculosis-infected macrophages. M. tuberculosis induced metabolic hallmarks of inflammatory macrophages and a prominent signature of cholesterol metabolism. We found that infected macrophages accumulate cholestenone, a mycobacterial-derived, oxidized derivative of cholesterol. We demonstrated that the accumulation of cholestenone in infected macrophages depended on the M. tuberculosis enzyme 3ß-hydroxysteroid dehydrogenase (3ß-Hsd) and correlated with pathogen burden. Because cholestenone is not a substantial human metabolite, we hypothesized it might be diagnostic of M. tuberculosis infection in clinical samples. Indeed, in 2 geographically distinct cohorts, sputum cholestenone levels distinguished subjects with tuberculosis (TB) from TB-negative controls who presented with TB-like symptoms. We also found country-specific detection of cholestenone in plasma samples from M. tuberculosis-infected subjects. While cholestenone was previously thought to be an intermediate required for cholesterol degradation by M. tuberculosis, we found that M. tuberculosis can utilize cholesterol for growth without making cholestenone. Thus, the accumulation of cholestenone in clinical samples suggests it has an alternative role in pathogenesis and could be a clinically useful biomarker of TB infection.

RESUMO

OBJECTIVES: Reducing inappropriate nursing home (NH) antibiotic usage by implementing stewardship programs is a national priority. Our aim is to evaluate the influence of antibiotic stewardship programs on antibiotic use rates in NHs over time. DESIGN: Retrospective, repeated cross-sectional analysis. SETTING AND PARTICIPANTS: Long-term residents not receiving hospice care in freestanding NHs that participated in 1 or both surveys in 2013 and 2017. METHODS: Survey data were merged with the Minimum Data Set and the Certification and Survey Provider Enhanced Reporting data. Our outcome was a binary indicator for antibiotic use. The main predictor was the NH antibiotic stewardship policy intensity. Using multivariate linear regression models adjusting for resident and facility characteristics that differed between the 2 years, we calculated antibiotic use rates in 2013 and 2017 for all residents, those with Alzheimer's disease, and those with any infection including urinary tract infections (UTIs). RESULTS: Our sample included 317,003 resident assessments from 2013 and 267,537 assessments from 2017, residing in 953 and 872 NHs, respectively. NH antibiotic stewardship policy intensity increased from 2013 to 2017 (P < .01) and among all NH residents, including those with Alzheimer's disease, antibiotic use rate decreased (P < .05), with 45% of the decline attributable to strengthening stewardship programs. For most residents, policy intensity was associated with decreased usage in residents with UTI. However, among Alzheimer's disease residents with a UTI, this association did not persist. CONCLUSIONS AND IMPLICATIONS: Although there was a decrease in antibiotic use in 2017, more time is needed to see the full impact of antibiotic stewardship policy into practice. Adjustments to programs that directly address barriers to implementation and appropriate UTI antibiotic use for residents with Alzheimer's disease are necessary to continue strengthening NH antibiotic stewardship and improve care.

RESUMO

OBJECTIVE: To identify if disparate trends in the access and use of nursing home (NH) services among Black and Latino older adults compared with White older adults persist. Access was operationalized as the NHs that served Black, Latino, and White residents. Use was operationalized as the utilization of NH services by Black, Latino, and White residents. DESIGN: This was an observational study analyzing facility-level data from LTCfocus for 2011 to 2017. SETTING AND PARTICIPANTS: All NH residents present in US NHs participating in the Centers for Medicare and Medicaid Services program on the first Thursday in April in the years 2011 to 2017. NHs with fewer than 4500 bed-days per year are excluded in the LCTfocus dataset. Black, Latino, and White were the racial/ethnic groups of interest. METHODS: We calculated the mean percentage of each racial/ethnic group in NHs (Black, Latino, White) annually along with the number of NHs that provided care for these groups. We conducted a simple trend analysis using ordinary least squares to estimate the change in NH access and use by racial/ethnic group over time. RESULTS: Our NH sample ranged from 15,564 in 2011 to 14,956 in 2017. Latino residents' use of NHs increased by 20.47% and Black residents increased by 11.42%, whereas there was a 1.36% decrease in White residents' use of NHs. In this 7-year span, there was a 4.44% and 6.41% decline in the number of NHs that serve any Black and Latino older adults, respectively, compared with a 2.26% decline in NHs that serve only White older adults (access). CONCLUSIONS AND IMPLICATIONS: Our findings reveal a continued disproportionate rise in Black and Latino older adults' use of NHs while the number of NHs that serve this population have declined. This work can inform federal and state policies to ensure access to long-term care services and supports in the community for all older adults and prevent inappropriate NH closures.

RESUMO

OBJECTIVES: Up to 15% of the 1.4 million US nursing home (NH) residents receive antibiotics daily. Antibiotic use in NHs is often inappropriate, contributing to quality and safety concerns as well as antibiotic resistance. Information technology (IT) maturity-defined as the extent to which facilities possess and use diverse technological devices and software that are integrated across resident care, clinical support, and administrative activities-may improve the tracking and reporting of antibiotic use in NH residents. Thus, this research explores trends in IT maturity over time and associations with antibiotic use in US NHs. DESIGN: Repeated cross-sectional study. SETTING AND PARTICIPANTS: Long-term resident assessments from a random sample of Medicare-certified US NHs over 4 consecutive years (2013-2017). METHODS: Three data sources were used: (1) 4 annual surveys measuring IT maturity, (2) Minimum Data Set (MDS) 3.0 assessments for resident characteristics, and (3) Certification and Survey Provider Enhanced Reporting data for facility characteristics. Nonadmission MDS assessments that were within a 90-day window of the IT survey were eligible. Descriptive statistics were examined. Bivariate and multivariate regressions using NH fixed effects were conducted controlling for resident and NH characteristics. RESULTS: There were 219,461 MDS assessments from 80,237 long-stay residents aged ≥65 years, living in 817 NHs. Trends in IT maturity increased significantly over 4 years. IT integration in administrative processes was positively associated with antibiotic use (AOR 1.072, 95% CI 1.025, 1.122). CONCLUSIONS AND IMPLICATIONS: IT components that integrate administrative activities, which can provide greater access to data sources across the organization as a whole, was associated with changes in antibiotic use. Further evaluation is needed to determine if antibiotic use is more appropriate with higher maturity such that policy makers can encourage IT with these capabilities to promote antibiotic stewardship.

RESUMO

BACKGROUND: Extrapulmonary tuberculosis (EPTB) has an increasing rate in Turkey. The reason remains largely unknown. A better understanding of the demographic and microbial characteristics of EPTB in the Turkish population would extend the knowledgebase of EPTB and allow us to develop better strategies to control tuberculosis (TB). METHODS: We retrospectively evaluated clinical and laboratory data of 397 bacteriologically-confirmed TB cases diagnosed during an eight year-period using by chi-square analysis and multivariate logistic regression model. RESULTS: Of the 397 study patients, 103 (25.9%) had EPTB and 294 (74.1%) had pulmonary tuberculosis (PTB). The most commonly seen two types of EPTB were genitourinary TB (27.2%) and meningeal TB (19.4%). TB in bone/joints, pleural cavity, lymph nodes, skin, and peritoneal cavity occurred at a frequency ranging from 9.7% to 10.7%. The age distribution was significantly different (P<0.01) between PTB and EPTB, with patients older than 45 years tending to have an increased risk of EPTB. Furthermore, the distribution of different types of EPTB differed significantly among age groups (P=0.03). Meningeal and bone and/or joint TB were more commonly observed among the male patients, while lymphatic, genitourinary, and peritoneal TB cases were more frequently seen among females. Unique strain infection was statistically significantly associated with EPTB (OR: 2.82, 95% CI [1.59, 5.00]) CONCLUSIONS: EPTB accounted for a significant proportion of TB cases in Malatya, Turkey between 2001 and 2007. The current study has provided an insight into the dynamics of EPTB in Malatya, Turkey. However, the risk factors for having EPTB in Malatya, Turkey remain to be assessed in future studies using population-based or randomly selected sample.

RESUMO

OBJECTIVE: Health disparities are pervasive in nursing homes (NHs), but disparities in NH end-of-life (EOL) care (ie, hospital transfers, place of death, hospice use, palliative care, advance care planning) have not been comprehensively synthesized. We aim to identify differences in NH EOL care for racial/ethnic minority residents. DESIGN: A systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and registered in PROSPERO (CRD42020181792). SETTING AND PARTICIPANTS: Older NH residents who were terminally ill or approaching the EOL, including racial/ethnic minority NH residents. METHODS: Three electronic databases were searched from 2010 to May 2020. Quality was assessed using the Newcastle-Ottawa Scale. RESULTS: Eighteen articles were included, most (n = 16) were good quality and most (n = 15) used data through 2010. Studies varied in definitions and grouping of racial/ethnic minority residents. Four outcomes were identified: advance care planning (n = 10), hospice (n = 8), EOL hospitalizations (n = 6), and pain management (n = 1). Differences in EOL care were most apparent among NHs with higher proportions of Black residents. Racial/ethnic minority residents were less likely to complete advance directives. Although hospice use was mixed, Black residents were consistently less likely to use hospice before death. Hispanic and Black residents were more likely to experience an EOL hospitalization compared with non-Hispanic White residents. Racial/ethnic minority residents experienced worse pain and symptom management at the EOL; however, no articles studied specifics of palliative care (eg, spiritual care). CONCLUSIONS AND IMPLICATIONS: This review identified NH health disparities in advance care planning, EOL hospitalizations, and pain management for racial/ethnic minority residents. Research is needed that uses recent data, reflective of current NH demographic trends. To help reduce EOL disparities, language services and cultural competency training for staff should be available in NHs with higher proportions of racial/ethnic minorities.
