Factors influencing unawareness of hypertension among older Mexican Americans.

BACKGROUND: The objective of the study was to identify factors associated with unawareness of hypertension among Mexican Americans age 65 years and older. METHODS: This was a population-based survey of 3,050 older Mexican Americans conducted in five Southwestern states in 1993-1994. An in-home interview included sociodemographics, review of medications, and blood pressure measurements. RESULTS: Sixty percent of all subjects were hypertensive, and 37% of these were unaware of their diagnosis. Unaware hypertensive had significantly higher mean blood pressures than did aware hypertensives (145.7/ 86.2 mm Hg vs 142.4/83.1 mm Hg). While 77% of aware hypertensives were treated, only 10% of unaware hypertensives were treated. In multivariate analyses, factors associated with unawareness included male gender (OR = 1.8), being married (OR = 1.6), having Medicaid (OR = 1.6), having made fewer than two visits to a doctor in the past year (OR = 2.8), having a history of heart disease (OR = 0.57) or stroke (OR = 0.37), and having poor self-reported health (OR = 0.43). CONCLUSION: Despite 3 decades of hypertension detection and education programs, unawareness of hypertension remains high among older Mexican Americans. There is a continued need for community-based education programs for hypertensives who are unaware of their diagnosis, and also there is need for programs to increase access to primary care physicians.

RESEARCH: Motives as Predictors of the Public's Attitudes Toward Solid Waste Issues.

/ Surveys focusing on solid-waste-related issues, conducted over a period of several years, provided data from independent samples of residents of a Midwestern, USA, community. The collection of these data yielded useful information about the relationship between residents' recycling motives and their attitudes toward solid waste management in light of several changes in the solid waste infrastructure of the community over that time. The initial survey assessed baseline beliefs and attitudes, while later surveys were conducted after the implementation of a community educational program and a curbside recycling program. The findings indicated that for recyclers and nonrecyclers, different motives predicted endorsement of solid waste programs and policies. Although a similar percentage of recyclers and nonrecyclers were in support of various proposed programs and policies, concern for the environment was found to be positively related to nonrecyclers' support of proposed programs, particularly before these programs were implemented. Prior to program implementation, motives other than environmental altruism were found to be related to recyclers' support of the programs. Additional findings support the idea that educational programs and increased accessibility to recycling opportunities affect the relationship between people's attitudes toward solid waste management and their recycling motives.

[Computer program for retinopathy of prematurity screening].

BACKGROUND: The goal of retinopathy of prematurity (ROP) screening is complete detection of all preterm infants with threshold ROP. AIM: We wanted to develop software to facilitate registration of ROP findings, checking due dates of re-examination, and evaluation of screening data. By means of complete and faultless registration and evaluation of the data of preterm infants, the effectiveness and safety of the screening should increase. METHODS: We developed software that runs under Microsoft Windows 3.1 or Windows 95 and is programmed in Microsoft Access Basic and Microsoft Visual Basic. The software allows all screening data to be registered and evaluated. Intuitive handling, third level of normalization in database architecture, and automatic plausibility checks guarantee the utmost integrity of data and efficacy of database. RESULTS AND CONCLUSION: To date, the software has been used routinely in 2000 examinations in 1000 preterm infants. Our software facilitates clinical management and evaluation of ROP screening, which therefore becomes more safe.

Cervical stump cancer: a study of 14 cases.

CASE REPORT: This is a report on 14 patients with cervical stump cancer, aged 30 to 68 years old (median = 53 years), seen in a public university hospital. Over a 15-year period, 363 cases of cervical cancer were treated, of which fourteen (3.85%) were in the cervical stump. The time interval between subtotal hysterectomy and the diagnosis of the neoplasm varied from 9 days to 27 years (median = 9.3 years). 28.6% of the patients were in stage I, 42.9% in stage II and 28.6% in stage III. Fibromyoma was the major reason for the subtotal hysterectomy. Three patients underwent Wertheim-Meigs surgery, 1 in association with radiotherapy, and the other 11 patients had radiotherapy alone. The survival ranged from 12 to 120 months (median = 53.3 months). CONCLUSION: Subtotal hysterectomy should be avoided whenever possible in populations with restricted access to screening programs for cancer of the uterine cervix.

Self-reported desire to improve colposcopic impressions.

BACKGROUND: Women who participate in cervical cancer screening programs must have access to high quality colposcopy services when their cytology test are abnormal. The purpose of this project is to evaluate colposcopic services currently available in New Hampshire and whether colposcopy providers are willing to network to maintain and improve their colposcopic pattern recognition skills in order to improve their colposcopic correlations. METHODS: A survey was mailed to 1314 providers throughout New Hampshire. The survey ascertained the extent of current colposcopic services in New Hampshire through practitioner and practice demographics, the cervical procedures performed, the self-reported colposcopy skill level, and the self-reported quality of past colposcopic education. It also measured interest in networking with others to improve their colposcopic pattern recognition skills. RESULTS: The survey response rate was 62%. 145 of the 810 respondents (18%) are currently performing colposcopies, indicating a statewide potential colposcopy accommodation rate of 3.5 to 7 women per month per colposcopist. 57% of the physician assistants, 59% of the family physicians, 75% of the gynecologists and 100% of the nurse practitioners were interested in enhancing their colposcopic pattern recognition skills by networking through quarterly meetings. CONCLUSIONS: The crude accommodation rate for colposcopy appears sufficient for the women of New Hampshire although the geographic distribution of the colposcopists is unknown. A majority of the colposcopists were interested in networking to improve their colposcopic pattern recognition skills, which could improve patient care.

Employer, insurance, and health system response to long-term sick leave in the public sector: policy implications.

This study has been conducted to describe the situation of long-term sick-listed persons employed in the public sector regarding the medical reasons of their sick leave, the duration of their problems, the duration of the actual sick leave, rehabilitation support, rehabilitation measures, and the persons expectations of the future. Response rate of a postal questionnaire, where 484 women and 51 men on long-term sick leave answered, was 69%. The study-group consisted of 90% women with a median age of 50 years. The most common reasons for sick listing were long-lasting musculoskeletal problems, especially neck/shoulder pain, low back pain and osteoarthritis or other joint problems and mental problems, especially depression and burn-out syndromes. Forty-seven procent of the men and 57% of the women had been on the sick list for more than a year. Only half of them had been subjected to the legally required rehabilitation investigation of the employer This half got access to rehabilitation programs and/or vocational rehabilitation to a greater extent than those who not had been subjected to rehabilitation investigation. Less than half had been in contact with the workplace-connected rehabilitation actors, the Occupational Health Service or the Trade Union. In spite of this the sick-listed persons had a positive view of their future return to work. For long-term sick-listed persons in the public sector, there is a great potential for improvements of the rehabilitation at the workplace arena, in the involvement and cooperation between the already existing rehabilitation actors, in order to promote return to work.

A system for automated procedure documentation.

Quantitative information regarding competency in performing procedures is invaluable in attesting to a house officer's abilities when assessments need to be made. Thus, the means by which procedures, proficiency, and experience can be recorded and organized in an automated fashion need not be any further away than the nearest micro-computer. The procedure documenting system (PDS) automates the documenting of procedures and quantitative information pertaining to these procedures, and shortens the time demanded of the house officer to document procedures from a mean of 5.5 to 1.9 min. This paper is a description of the work done to automate the recording of procedures performed by housestaff at a teaching hospital and the acceptance by housestaff. This computer program takes the specific information and places it into a specialized database so that house officers can have detailed documentation attesting to their proficiency in various procedures. In addition, the program director can access the database to document the quantity of procedures to which an individual house officer has attained competence.

Delegation of responsibility in maternity care in Karawa rural health zone, Zaire.

Karawa Health Zone (KHZ) located in northwestern Zaire, comprises 19,000 km2 with about 340,000 inhabitants. As part of an expanding primary health care program, KHZ officials instituted an extensive outreach program to increase access of women to maternity care. General practitioner (GP) doctors, nurses, midwives, auxiliaries, and traditional birth attendants share responsibilities in delivering maternity care services. Nurses and midwives perform most of the obstetric functions at the Karawa Hospital Maternity Center. Data from 1988 to 1990 show that nurses and midwives attended 98% of normal deliveries and 81% of the complicated ones. Selected nurses performed cesarean section routinely. There was no significant difference in maternal and neonatal outcomes for cesarean section performed by nurses and GPs. Physicians on staff provided support through monitoring, supervision, training, and care for the most complicated cases.

Patient retention in mobile and fixed-site methadone maintenance treatment.

The retention of patients (n = 399) enrolled in mobile health services (MHS), a Baltimore outpatient mobile methadone treatment program, was compared to patient retention (n = 1588) in six Baltimore fixed-site programs. Mobile program patients were retained for a median of 15.53 months in treatment in comparison to 3.90 for fixed-site patients (n = 664) from the MHS served zip codes (MHSZIPS) and 6.27 for fixed-site patients (n = 924) from zip codes other than those served by MHS (OTHERZIPS), (P < 0.001). Using Cox regression, the characteristics of patients associated with earlier discharge were (1) higher number of arrests, (2) more frequent cocaine use and (3) lower family income. These predictors of shorter retention were generally more prevalent among patients from the MHS served zip codes. Therefore, the longer retention in treatment of MHS patients as compared to OTHERZIPS fixed-site program patients is even more striking. Consistent with these differences in retention, were finding in a prior study suggesting that the mobile program provided greater access to services in reducing patient transportation cost and travel time. Thus, mobile methadone maintenance treatment appears to be a useful means of providing services.

[Education for chronic cardiologic diseases in a transversal multidisciplinary unit: the experience of a general hospital center].

Treatments for congestive heart failure, hypertension and cardiovascular risk have significantly changed and have become more complex. The have also become more and more effective thanks to the results of great clinical studies that have enabled European and North-American societies to issues recommendations. The observance of the pharmacological and non-pharmacological treatments requires the education of patients and their family following guidelines that have been clearly defined by the European Society of Cardiology. This education, in which the technic of communication is very important, is common to a lot of chronic diseases and requires adequate material and human resources in order to have an optimal quality of treatment. In a society in which spending is on rise, getting such resources is not easy. However, putting in common resources of several departments can be a good solution. The experience of the Hospital Center of Douai (France) lead to the creation of a Transversal Education Unit at the end of the year 2003. This unit centralizes the efforts of several departments of care like pneumology, pediatrics, diabetology, nutrition and cardiology and allows patients suffering from co-morbidities to have access to various programs of this unit.

Multiome Perturb-seq unlocks scalable discovery of integrated perturbation effects on the transcriptome and epigenome.

Single-cell CRISPR screens link genetic perturbations to transcriptional states, but high-throughput methods connecting these induced changes to their regulatory foundations are limited. Here, we introduce Multiome Perturb-seq, extending single-cell CRISPR screens to simultaneously measure perturbation-induced changes in gene expression and chromatin accessibility. We apply Multiome Perturb-seq in a CRISPRi screen of 13 chromatin remodelers in human RPE-1 cells, achieving efficient assignment of sgRNA identities to single nuclei via an improved method for capturing barcode transcripts from nuclear RNA. We organize expression and accessibility measurements into coherent programs describing the integrated effects of perturbations on cell state, finding that ARID1A and SUZ12 knockdowns induce programs enriched for developmental features. Modeling of perturbation-induced heterogeneity connects accessibility changes to changes in gene expression, highlighting the value of multimodal profiling. Overall, our method provides a scalable and simply implemented system to dissect the regulatory logic underpinning cell state. A record of this paper's transparent peer review process is included in the supplemental information.

Meta-PseU: A meta-classifier for robust prediction of RNA pseudouridine modification sites from long sequences.

BACKGROUND AND OBJECTIVES: Pseudouridine (&#x3a8;) represents one of the most abundant and conserved RNA modifications. &#x3a8; provides an additional hydrogen-bond donor that enhances RNA structural stability and modulates translation. It participates in diverse biological processes, including RNA-protein interactions, splicing, translational control, and stress responses. Aberrant pseudouridylation is implicated in cancer, neurodegenerative disorders, and autoimmune diseases. Despite its biological importance, experimental identification of &#x3a8; sites remains time-consuming and costly, limiting the feasibility of transcriptome-wide profiling. Computational approaches have therefore become essential complements to experimental techniques. However, state-of-the-art machine-learning and deep-learning predictors often suffer from limited generalizability due to small training datasets. To overcome these issues, we aim at constructing new long-sequence datasets and developing a novel &#x3a8; site predictor. METHODS: New long-sequence datasets were constructed as benchmarks for RNA &#x3a8;-site prediction. The &#x3a8; modification sites in RMBase 3.0 were mapped to the reference genomes across three species of human, mouse, and yeast, and the RNA sequences with a length of 201 were generated by extending the upstream and downstream from the mapped, central sites. To eliminate sequence redundancy, the sequences were clustered using CD-HIT with a 70% sequence identity threshold. We developed Meta-PseU, a logistic regression-based meta-classifier that considered 118 machine learning and deep learning classifiers. The datasets and programs are freely accessible at https://github.com/kuratahiroyuki/MetaPseU. RESULTS: By optimizing model configuration, we proposed the Meta-PseU model stacking 32 machine learning and deep learning classifiers out of 118 classifiers. Meta-PseU substantially improved model generalizability, overcoming a key limitation of existing approaches. It greatly outperformed state-of-the-art predictors and achieved increasing accuracy with increasing sequence length. CONCLUSIONS: Long-sequence datasets were newly constructed as benchmarks for RNA &#x3a8;-site prediction. Meta-PseU offers a new framework for robust &#x3a8;-site identification by using long sequences.

The relationship between HAART use and employment for HIV-positive individuals: an empirical analysis and policy outlook.

OBJECTIVE: This study jointly analyzes the determinants of the use of highly active antiretroviral therapy (HAART) along with the determinants of employment status for human immunodeficiency virus (HIV)-positive individuals. METHODS: Data from the HIV Cost and Services Utilization Study (HCSUS) were analyzed using a bivariate probit model. HSCUS collected data on 2864 individuals in 180 clinics, hospitals and private practices in 28 urban areas and 24 clusters of rural counties in the United States. We used data from the baseline interview to categorize individuals as employed or unemployed and for the determination of HAART use. RESULTS: The empirical results suggest that individuals taking HAART have an increased likelihood of working and that individuals with private health insurance are more likely to use HAART compared to individuals with public health insurance coverage or no coverage. CONCLUSIONS: Due to the fact that employment of HIV-positive is directly related to HAART use, policymakers need to look to the private health insurance industry and public program to increase access to HAART. Suggested models for consideration are mandating insurance benefits and ADAP expansion.

Primary screening for cervical cancer through self sampling.

OBJECTIVE: To evaluate the use of community health agents (CHAs) to instruct women living in poor rural areas in obtaining self-collected cervical samples and compare the high-risk HPV (hrHPV) hybrid capture (HC) results obtained to those for gynecologist-collected samples. METHODS: After a one-day training, CHAs visited sexually active women, instructing each in the use of collection brush and the Universal Collection Medium tube. One week thereafter, a gynecologist collected cervical samples from, and performed colposcopies on, the same women. A single reference lab performed all HCs. RESULTS: 878 women (Age: 15-69 years) participated. Among self-collected samples, hrHPV prevalence was 33.9% (95% CI: 30.8%-37%), compared with 28.6% (95% CI: 27%-30%) among gynecologist-collected samples. However, 9.3% of the patients were HPV HC II-positive in the self-collected sample and HPV HC II-negative in the gynecologist-collected samples (95% CI: 7.38%-11.22%), whereas 4% tested positive in gynecologist-collected samples and negative in self-collected samples (95% CI: 2.7%-5.3%) (P<0.01; kappa=0.7). Of 9 cases of histologically-confirmed, high-grade squamous intraepithelial lesion, self-collected and provider-collected samples missed one each. CONCLUSION: Self-collected vaginal sampling could be made an additional CHA function under existing program conditions, improving access to cervical cancer screening in poor rural settings.

Twelve-month prevalence, correlates, and treatment preference of adults with DSM-IV major depressive episode in Hong Kong.

BACKGROUND: The most recent large-scale community mental health survey of depression among adults in Hong Kong was conducted over two decades ago. The lifetime prevalence rates of DSM-III major depressive disorder (females 2.44% and males 1.29%) in that study do not tally with several indices of worsened social health and clinical prevalence studies of depression in contemporary Hong Kong. METHODS: Each of 5004 adults randomly drawn from the general population completed a telephone interview that generated the DSM-IV-based diagnosis of major depressive episode (MDE), sociodemography, help-seeking, and other epidemiological data. RESULTS: Twelve-month prevalence of MDE was 8.4%. The female-to-male ratio was low but typical of surveys in Chinese communities. Female sex and unemployment were associated with increased risk. 32.5% of respondents with MDE reported frequent thoughts of suicide. Recognition of the need for treatment of depression was high but actual treatment rate and preference for mental health specialists were low. LIMITATIONS: Response rate was low though cooperation rate was moderately high. Detailed demography, comorbidity, and clinical reappraisal interviews were not covered. CONCLUSIONS: Resolving issues of stigma and mode of symptom elicitation may lead to more valid prevalence estimates of depression among Chinese people. Although longitudinal studies are needed to confirm a genuine increase in prevalence, depression is likely to be more common in Hong Kong than previously suggested. High recognition of the need for treatment but low rate of actual treatment calls for policy and programs that improve access to treatment.

The PLUNC 3D treatment planning system: a dynamic alternative to commercially available systems.

Three-dimensional (3D) treatment planning is an integral step in the treatment of various cancers when radiation is prescribed as either the primary or adjunctive modality, especially when the gross tumor volume lies in a difficult to reach area or is proximal to critical bodily structures. Today, 3D systems have made it possible to more precisely localize tumors in order to treat a higher ratio of cancer cells to normal tissue. Over the past 15 years, these systems have evolved into complex tools that utilize powerful computational algorithms that offer diverse functional capabilities, while simultaneously attempting to maintain a user-friendly quality. A major disadvantage of commercial systems is that users do not have access to the programming source code, resulting in significantly limited clinical and technological flexibility. As an alternative, in-house systems such as Plan-UNC (PLUNC) offer optimal flexibility that is vital to research institutions and important to treatment facilities. Despite this weakness, commercially available systems have become the norm because their commissioning time is significantly less and because many facilities do not have computer experts on-site.

Prevalence of lens opacities in Latinos: the Los Angeles Latino Eye Study.

OBJECTIVE: To estimate the age- and gender-specific prevalence of posterior subcapsular (PSC), nuclear, cortical, and mixed lens opacities in a population-based sample of Latinos 40 years and older. DESIGN: Population-based, cross-sectional study. PARTICIPANTS: Six thousand three hundred fifty-seven Latinos 40 years and older from 6 census tracts in Los Angeles, California. METHODS: A population-based sample of Latinos underwent a complete eye examination, including assessment of presence and severity of lens opacification, using the slit lamp-based Lens Opacities Classification System II (LOCS II). All lens changes (including pseudophakia/aphakia); any nuclear, PSC, and cortical opacities; and nuclear-only, PSC-only, and cortical-only opacities were evaluated. Frequency distributions and chi-square test analyses were used to determine the age- and gender-specific prevalences for each opacity type. MAIN OUTCOME MEASURES: Prevalences of cortical, nuclear, and posterior subcapsular opacities. RESULTS: Of the 7789 eligible subjects, 6357 completed a clinical examination (82% participation rate). Of all participants with LOCS II grading, 20% had all lens changes, 7.6% had cortical-only opacities, 3.5% had nuclear-only opacities, 0.4% had PSC-only opacities, and 5.9% had mixed-type opacities. The prevalence of all types of lens opacities increased with age (P<0.0001). Of all participants with mixed opacities, 49% had monocular visual impairment and 20% had binocular impairment. Of all 6357 participants, 3.9% had undergone cataract extraction in at least one eye. CONCLUSION: Our data provide the first population-based estimates of the prevalence and severity of lens opacities in Latinos. Cortical opacities were the most common type. The high rate of visual impairment from lens opacities suggests that programs that increase access to cataract surgery for older Latinos could help to reduce the burden of visual impairment in the United States.
