The Association Between Tobacco Retailer Outlet Density and Prevalence of Cigarette Smoking in Virginia.

OBJECTIVE: We examine the association between tobacco retail outlet density and adult smoking prevalence at the county level in Virginia, controlling for spatial autocorrelations. AIMS AND METHODS: Pooling data from 2020 County Health Rankings (compiled data from various sources including, but not limited to, the National Center for Health Statistics-Mortality Files, the Behavioral Risk Factor Surveillance System (BRFSS), and the American Community Survey) and Counter Tools, we conducted regression analyses that accounted for spatial autocorrelation (spatial lag models, LMlag) and adjusted for county-level access to healthcare, demographics, SES, environmental factors, risk conditions or behaviors, and population health measures. RESULTS: Our estimates provide evidence that every increase of one tobacco retail outlet per 1000 persons was associated with 1.16 percentage points (95% CI: 0.80-1.52) higher smoking prevalence at the county level in Virginia after controlling for spatial autocorrelation. The effect of outlet density was largely explained by social determinants of health such as SES, risky conditions or behaviors, and environmental factors. We further noticed that the impact of social determinants of health were closely related and can be explained by indicators of population health (rates of mental distress (ß = 1.49, 95% CI: 1.31-1.67) and physical inactivity (ß = 0.07, 95% CI: 0.04-0.10). CONCLUSIONS: Although higher tobacco outlet density was associated with an increase in county-level smoking prevalence, the impact of outlet density was largely explained by social determinants of health and mental illness. Improving well-being at the community level could be a promising strategy in future tobacco control policies. IMPLICATION: The influence of tobacco outlet density seems to be explained by other social determinants of health and population level of mental or physical health. Thus, efforts to reduce tobacco use and consequent negative health effects should explore the impact of improving regional living standards. However, a sole focus on economic growth may not be sufficient, whereas a focus on such things as promoting work-life balance and improving overall well-being at the community level may be more.

Non-invasive assessment of left ventricular relaxation property using color M-mode-derived intraventricular pressure gradients in cats.

INTRODUCTION: Diastolic dysfunction is an early clinical feature of feline hypertrophic cardiomyopathy (HCM). The left ventricular filling in early diastole is facilitated by the diastolic intraventricular pressure gradient (IVPG). The study objectives were to evaluate color Doppler M-mode-derived IVPG calculation in cats as a non-invasive assessment of the left ventricular relaxation property to determine the normal ranges of peak IVPG in cats and investigate the influence of left ventricular function and heart rate (HR). ANIMALS: One hundred and six client-owned apparently healthy cats. METHODS: Prospective cross-sectional study. Quantitative analysis of color Doppler M-mode images was used to estimate total and segmental IVPGs non-invasively. RESULTS: The total IVPG was 0.76 mmHg (95% reference interval (RI): 0.28-1.29 mmHg), the basal IVPG 0.34 mmHg (95% RI: 0.07-0.63 mmHg), and the mid-apical IVPG 0.42 mmHg (95% RI: 0.15-0.71 mmHg). Total and segmental IVPG increased with HR (P < 0.003), while segmental percent IVPG was HR independent. A short isovolumic relaxation time (IVRT) and a high mitral annular velocity in early diastole were associated with an increase in total IVPG (P = 0.008 and P = 0.009, respectively) adjusted for HR. An increase in IVPG was associated with an increase in mitral inflow velocity (P < 0.001). CONCLUSIONS: Feline IVPGs increase with HR and a short IVRT, which was believed to be a normal physiologic adrenergic response associated with an increased sympathetic tone. Future studies of segmental IVPG changes in feline HCM are needed to evaluate the clinical applicability of color Doppler M-mode estimated IVPGs in feline cardiology.

[Glaucoma in inpatient care in Germany in 2015]. / Glaukome im stationären Leistungsgeschehen in Deutschland in 2015.

AIM: Analysis of structural characteristics of inpatient treatment of glaucoma in clinical units run by affiliated physicians and those run by hospital physicians in Germany are described. The frequency and distribution of glaucoma diagnoses as the main and secondary diagnosis at different departments and glaucoma diagnoses, number of cases, surgeries and procedures and patient characteristics of the four glaucoma-specific diagnosis-related groups (DRG) are presented. METHOD: Secondary data analysis using the G­DRG browser from 2015/2016 provided by the German Institute for Remuneration Systems in Hospitals. RESULTS: In 30% of the 156,524 cases glaucoma was classified as the main diagnosis, in 24% as secondary diagnosis in ophthalmological departments and 46% as secondary diagnosis in other departments. Primary open angle glaucoma was reported most frequently (40%), whilst non-ophthalmological departments mainly coded as "other" or "unspecified types of glaucoma". Glaucoma was coded in 20 DRGs as the main diagnosis and in all ophthalmic DRGs as secondary diagnosis. The number of cases and procedures differed among the four glaucoma-specific DRGs (C06Z, C07A, C07B, C64Z), the diagnostic spectrum, however, was similar. Patients were mainly women, older and with few comorbidities or complications. The C64Z was mainly characterized by cases with "suspected glaucoma" and only conservative procedures. Only 6% of the glaucoma patients were treated in clinical units run by affiliated physicians. In contrast to units run by hospital physicians surgical DRGs and operations prevailed but the diagnostic spectrum and patient characteristics were not different. DISCUSSION AND CONCLUSION: With 20% of the main diagnoses, glaucoma was highly relevant for inpatient ophthalmological care. Glaucoma as a secondary diagnosis was also common in other medical specialties, though no diagnostic differentiation was made here. Patients with glaucoma are mainly treated in clinical units run by hospital physicians. Nevertheless, patients of affiliated physicians showed the same characteristics.

Toxicity Assessment of a Phase III Study Evaluating FEC-Doc and FEC-Doc Combined with Gemcitabine as an Adjuvant Treatment for High-Risk Early Breast Cancer: the SUCCESS-A Trial.

Introduction: This paper aims to evaluate the toxicity profile of additive gemcitabine to adjuvant taxane-based chemotherapy in breast cancer patients. Methods: Patients enrolled in this open-label randomized controlled Phase III study were treated with 3 cycles of epirubicin-fluorouracil-cyclophosphamide (FEC) chemotherapy followed by 3 cycles of docetaxel with those receiving 3 cycles of FEC followed by 3 cycles of gemcitabine-docetaxel (FEC-DG). 3690 patients were evaluated according to National Cancer Institute (NCI) toxicity criteria (CTCAE). The study medications were assessed by the occurrence of grade 3-4 adverse events, dose reductions, postponements of treatment cycles and granulocyte colony-stimulating factor (G-CSF) support. Results: No differences in neutropenia or febrile neutropenia were demonstrated. However, thrombocytopenia was significantly increased with FEC-DG treatment (2.0 vs. 0.5 %, p < 0.001), as was leukopenia (64.1 vs. 58.5 %, p < 0.001). With FEC-DG significantly more G-CSF support in cycles 4 to 6 (FEC-DG: 57.8 %, FEC-D: 36.3 %, p < 0.001) was provided. Transaminase elevation was significantly more common with FEC-DG (SGPT: 6.3 %, SGOT: 2 %), whereas neuropathy (1.2 %), arthralgia (1.6 %) and bone pain (2.6 %) were more common using FEC-D. Dose reductions > 20 % (4 vs. 2.4 %) and postponement of treatment cycles (0.9 vs. 0.4 %) were significantly more frequent in the FEC-DG arm. Eight deaths occurred during treatment in the FEC-DG arm and four in the FEC-D arm. Conclusion: The addition of gemcitabine increased hematological toxicity and was associated with more dose reductions and postponements of treatment cycles.

The prevalence and correlates of untreated serious mental illness.

OBJECTIVE: To identify the number of people in the United States with untreated serious mental illness (SMI) and the reasons for their lack of treatment. DATA SOURCE/STUDY DESIGN: The National Comorbidity Survey; cross-sectional, nationally representative household survey. DATA COLLECTION: An operationalization of the SMI definition set forth in the Alcohol, Drug Abuse, and Mental Health Administration Reorganization Act identified individuals with SMI in the 12 months prior to the interview. The presence of SMI then was related to the use of mental health services in the past 12 months. PRINCIPAL FINDINGS: Of the 6.2 percent of respondents who had SMI in the year prior to interview, fewer than 40 percent received stable treatment. Young adults and those living in nonrural areas were more likely to have unmet needs for treatment. The majority of those who received no treatment felt that they did not have an emotional problem requiring treatment. Among those who did recognize this need, 52 percent reported situational barriers, 46 percent reported financial barriers, and 45 percent reported perceived lack of effectiveness as reasons for not seeking treatment. The most commonly reported reason both for failing to seek treatment (72 percent) and for treatment dropout (58 percent) was wanting to solve the problem on their own. CONCLUSIONS: Although changes in the financing of services are important, they are unlikely by themselves to eradicate unmet need for treatment of SMI. Efforts to increase both self-recognition of need for treatment and the patient centeredness of care also are needed.

Predicting whether patients receive continuity of care after discharge from state hospitals: policy implications.

This article reports the results of a comprehensive study of predictors of factors influencing continuity of care for individuals discharged from state hospitals to communities. Continuity of care is defined and the predisposing, enabling and need factors are examined using a statewide database. The conceptual model is based on community support system principles, and it drives the research. The findings will influence policy, which will then affect community support system principles. Logistic regression analysis is employed as statistical analysis that lends itself to graphical form. Implications for policy and future research are presented.

The provision of services for rural youth with serious emotional and behavioral problems: Virginia's Comprehensive Services Act.

The problems of the delivery of mental health and social services to rural children and adolescents encapsulate many of the problems in the larger health care system. Consequently, many of the principles underlying the President's Health Security Plan are applicable to the reformation of this more specialized service system. The experience of the Commonwealth of Virginia in implementing the Comprehensive Services Act (CSA) highlights the scope of vision needed to transform an existing service delivery system into a coordinated system of care on a state-wide scale.

Rural and urban differences in continuity of care after state hospital discharge.

In a study to determine differences in continuity of care for state hospital patients discharged to rural and urban areas, all community mental health centers in Virginia were asked to complete a brief questionnaire about each patient discharged to the centers in fiscal year 1992. Discharges to rural centers had significantly higher levels of continuity of care on four of five dimensions of continuity. The authors conjecture that rural centers' lower staff ratios and decreased role boundaries may make them better able than urban centers to carry out the diverse tasks needed to help discharged patients resume community living.

Clinical utility and cost effectiveness of Helicobacter pylori testing for patients with duodenal and gastric ulcers.

OBJECTIVE: current consensus guidelines recommend that all patients demonstrating either a gastric or duodenal ulcer be tested for Helicobacter pylori, the most common cause of ulcers. We determined the clinical utility and cost effectiveness of H. pylori testing in patients with duodenal and gastric ulcers. METHODS: A retrospective evaluation and cost-effectiveness analysis of 565 consecutive patients with endoscopically demonstrated gastric or duodenal ulcers over a 4-yr period in a large, urban general hospital. The main outcome variables are the percentage of patients who had a gastric biopsy, the prevalence of H. pylori, and the cost effectiveness of testing (antral biopsy, CLO test, serum antibody, and urea breath test) for H. pylori. RESULTS: Significantly more patients with endoscopically documented duodenal ulcers had an antral biopsy performed in 1993 and 1994 when compared with patients from 1991 and 1992 (p < 0.00001). For patients with gastric ulcers, biopsies were performed at a similar rate throughout this study. Overall, patients with duodenal and gastric ulcers demonstrated H. pylori 75% and 69% of the time, respectively. The total charges for biopsy documentation and treatment of H. pylori in all duodenal ulcer patients in this cohort was estimated at $25,135. If a biopsy for H. pylori had been performed in all patients the actual charges would have been $77,443. Conversely, charges would have been only $8085 had all patients been empirically treated for H. pylori based on the high pretest probability of infection. CONCLUSIONS: Routine testing for H. pylori is very expensive, regardless of the diagnostic method used. Biopsy results do not provide clinically useful information in most patients with duodenal ulcers and may be misleading if falsely negative.

Geographic after-tax real income differentials and population growth rates.

"The purpose of this [one-page] note is to empirically investigate the impact of geographic after-tax real income differentials on geographic population growth rate differentials. The focus is on population growth rates in Florida's 67 counties over the period 1980-88." The authors conclude that "even after allowing for a variety of other location-influencing factors, including coastal access, after-tax real income differentials exercise a positive and significant impact on population growth rate differentials among Florida's counties."

Incidence and management of severe hypoglycemia in 434 adults with insulin-dependent diabetes mellitus.

The risk of severe hypoglycemia associated with the particular therapeutic approach of two University hospitals was assessed in 96% of all patients with insulin-dependent diabetes mellitus (IDDM) who had been admitted during a period of almost 3 yr to the diabetic wards of two hospitals and who participated in a structured teaching and treatment program. During a mean follow-up period of 18 mo, 10% of the conventionally treated patients (N = 384; age 30 +/- 13 yr; duration of diabetes 12 +/- 9 yr) and 9% of the CSII-treated patients (N = 50, age 28 +/- 7 yr, duration of diabetes 13 +/- 7 yr, total follow-up period 1093 patient-mo) experienced at least one severe hypoglycemic episode per year, and a total of 123 severe hypoglycemic episodes occurred. In a subgroup of 169 conventionally treated patients, mean glycosylated hemoglobin values decreased from 10.5 +/- 1.9% before participation in the program to 9.2 +/- 2.0% (P less than 0.001) 18 +/- 4 mo thereafter. For the CSII-treated patients, glycosylated hemoglobin values were 9.7 +/- 1.9% before initiation of pump therapy and remained at the upper normal range from 3 mo thereafter throughout the study. There was no relationship between glycosylated hemoglobin levels and the occurrence of severe hypoglycemic episodes. Fifty-three severe hypoglycemic episodes were treated with glucagon injections by the patients' relatives (all but one effectively), 30 were managed by assisting physicians, and 44 led to hospitalization. Thus, successful attempts to improve glycosylated hemoglobin values in an unselected group of patients with IDDM were not associated with an unduly high risk of severe hypoglycemia when compared with the scarce data from the literature.

The use of the EEG for assessment of vigilance changes caused by beta-blockers.

The aim of this study was to investigate the changes of vigilance caused by beta-blockers. A recently developed method to measure the vigilance fluctuations, based on the EEG spectra, was employed together with self-rating. Repeated vigilance measurements were made in 20 healthy volunteers before and after administration of placebo, propranolol and metoprolol in random sequence. Both EEG analysis and self-rating confirmed that the vigilance level was significantly decreased after administration of beta-blockers compared to placebo. No significant difference between propranolol and metoprolol could be found. The results suggest that the decrease in systolic blood pressure after beta-blockade may be responsible for the drug-induced drowsiness. However, some of the observations made in the study can be interpreted as indirect proof that central mechanisms are also involved, and that both propranolol and metoprolol have sedative properties comparable to those observed with conventional psychotropic drugs.
