Central corneal thickness, intraocular pressure, and degree of myopia in an adult myopic population aged 20 to 40 years in southeast Spain: determination and relationships.

Objective: To determine the values of, and study the relationships among, central corneal thickness (CCT), intraocular pressure (IOP), and degree of myopia (DM) in an adult myopic population aged 20 to 40 years in Almeria (southeast Spain). To our knowledge this is first study of this kind in this region. Methods: An observational, descriptive, cross-sectional study was done in which a sample of 310 myopic patients (620 eyes) aged 20 to 40 years was selected by gender- and age-stratified sampling, which was proportionally fixed to the size of the population strata for which a 20% prevalence of myopia, 5% epsilon, and a 95% confidence interval were hypothesized. We studied IOP, CCT, and DM and their relationships by calculating the mean, standard deviation, 95% confidence interval for the mean, median, Fisher’s asymmetry coefficient, range (maximum, minimum), and the Brown-Forsythe’s robust test for each variable (IOP, CCT, and DM). Results: In the adult myopic population of Almeria aged 20 to 40 years (mean of 29.8), the mean overall CCT was 550.12 μm. The corneas of men were thicker than those of women (P = 0.014). CCT was stable as no significant differences were seen in the 20- to 40-year-old subjects’ CCT values. The mean overall IOP was 13.60 mmHg. Men had a higher IOP than women (P = 0.002). Subjects over 30 years (13.83) had a higher IOP than those under 30 (13.38) (P = 0.04). The mean overall DM was −4.18 diopters. Men had less myopia than women (P < 0.001). Myopia was stable in the 20- to 40-year-old study population (P = 0.089). A linear relationship was found between CCT and IOP (R2 = 0.152, P ≤ 0.001). CCT influenced the IOP value by 15.2%. However no linear relationship between DM and IOP, or between CCT and DM, was found. Conclusions: CCT was found to be similar to that reported in other studies in different populations. IOP tends to increase after the age of 30 and is not accounted for by alterations in CCT values.

Health for life : annual report of activities for the period January-December 2013

In Seychelles, cardiovascular diseases (CVD), notably stroke, ischemic heart disease and hypertensive heart disease has become the largest contributor of deaths (40%) in the entire population. CVD also results in a large burden of disability and also has subsequent social and economic impact. The Unit for Prevention and Control of Cardiovascular Diseases (UPCCD) provides leadership, expertise and capacity at national level for the surveillance, prevention and control of cardiovascular diseases through education, programs and input into policy.

Perinatal assessment of infant, parents, and parent-infant relationship: prematurity as an example.

This article reviews the stresses for parents, infants, and other caregivers during the period surrounding the birth of the premature infant. Principles of assessment of infant discomfort, parental stress, the parent-infant relationship, and the match of the medical caregiving environment to the individual infant's needs are discussed. Relevant tools to aide in these aspects of assessment are reviewed. The role of early assessment as preventive intervention and the indication for subsequent intervention in complicated cases of premature infants and their parents are further discussed. The article offers detailed clinical examples to illustrate these and other points throughout.

Prevención de la transmisión sexual del VIH en adolescentes

En una muestra de 119 estudiantes de cuarto de Educación Secundaria Obligatoria (ESO) y primerode Bachillerato (52,6% mujeres) se analizan los conocimientos sobre la prevención de latransmisión sexual del virus del sida, las expectativas de resultados y de autoeficacia respecto a losmétodos preventivos y el tipo de prevención utilizada durante la última relación sexual. Para evitarlas respuestas inducidas respecto a los comportamientos preventivos se emplea un formato de preguntaabierta. Los resultados muestran que sólo el 23,5% de los estudiantes han dado dos respuestastotalmente correctas sobre estrategias consideradas eficaces en la prevención sexual del VIH:uso del preservativo y abstinencia (por este orden). El 70,5% valoran totalmente o muy eficaz elpreservativo para evitar la transmisión sexual del VIH y el 95% de los que dan la segunda respuestajuzgan totalmente eficaz la práctica de la abstinencia con la misma finalidad. En el caso del preservativose sienten totalmente o muy capaces de usarlo el 64,3%, mientras que cuando se trata de laabstinencia sólo se perciben con esa competencia el 20%. Por lo que se refiere al uso autoinformadode métodos preventivos en la última relación, por parte de los 29 estudiantes que tuvieronactividad sexual durante el mes anterior, se observa que 21 de ellos emplearon el preservativo, dosla píldora anticonceptiva, otros dos no precisan el tipo de precaución y el resto no tomó ninguna.Tanto el reducido nivel de conocimientos sobre prevención, como la baja percepción de autoeficaciapara mantenerse abstinentes, nos alertan sobre la necesidad de hacer un mayor esfuerzo de informaciónpara eliminar creencias equivocadas, como por ejemplo: sobre la pretendida eficacia protectorade tener relaciones sexuales con una pareja estable o conocida. Así mismo, conviene insistiren el uso del preservativo como anticonceptivo de elección entre los adolescentes

Malaria: une espèce en voie de disparition [Malaria: an endangered species?].

The implementation at scale of preventive measures and the use of effective treatments in populations living in endemic areas has led to a drastic reduction of the burden of malaria in all continents. The considerable investment of international agencies to support local governments in the fight against malaria allows hoping to achieve the millennium goals for malaria and child mortality in several countries. Malaria elimination, and even eradication becomes a realistic objective, especially so because a vaccine may be soon available to complement the armamentarium. For travelers, the tendency will be to reduce the number of countries where chemoprophylaxis or stand-by treatment is recommended and to insist on the rigorous use of measures to prevent mosquito bites such as repellents and insecticide-impregnated bednets.

Talking about sexuality with the physician: are patients receiving what they wish?

QUESTIONS UNDER STUDY/PRINCIPLES: Little is known concerning patients' expectations regarding sexual history taking by doctors: to ascertain expectations and actual experience of talking about sexuality among male patients attending outpatient clinics, and their sexual behaviour. METHODS: Patients consecutively recruited from two outpatient clinics in Lausanne, Switzerland were provided with an anonymous self-administered questionnaire. Survey topics were: patients' expectations concerning sexual history taking, patients' lifetime experience of sexual history taking, and patients' sexual behaviour. RESULTS: The response rate was 53.0% (N = 1452). Among respondents, 90.9% would like their physician to ask them questions regarding their sexual history in order to receive advice on prevention (60.0% yes, 30.9% rather yes). Fifteen percent would be embarrassed or rather embarrassed if asked such questions. Nevertheless, 76.2% of these individuals would like their physician to do so. Despite these wishes, only 40.5% reported ever having a discussion "on their sexual life in general" with a doctor. Only one patient out of four to five was asked about previous sexually transmitted infections (STIs), the number of sexual partners and their sexual orientation. No feature of their sexual life distinguishes those who had discussed sexual issues with a doctor from those who had not, except a history of previous consultation for health problems related to sexuality. Conversely, being embarrassed about conducting this discussion was significantly associated with lack of discussion regarding sexuality. CONCLUSIONS: This study highlights the gap existing in the field of STI prevention in terms of doctors' advice and patients' wishes.

Impact of pharmacist care in the management of cardiovascular disease risk factors: a systematic review and meta-analysis of randomized trials.

BACKGROUND: Pharmacists may improve the clinical management of major risk factors for cardiovascular disease (CVD) prevention. A systematic review was conducted to determine the impact of pharmacist care on the management of CVD risk factors among outpatients. METHODS: The MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials databases were searched for randomized controlled trials that involved pharmacist care interventions among outpatients with CVD risk factors. Two reviewers independently abstracted data and classified pharmacists' interventions. Mean changes in blood pressure, total cholesterol, low-density lipoprotein cholesterol, and proportion of smokers were estimated using random effects models. RESULTS: Thirty randomized controlled trials (11 765 patients) were identified. Pharmacist interventions exclusively conducted by a pharmacist or implemented in collaboration with physicians or nurses included patient educational interventions, patient-reminder systems, measurement of CVD risk factors, medication management and feedback to physician, or educational intervention to health care professionals. Pharmacist care was associated with significant reductions in systolic/diastolic blood pressure (19 studies [10 479 patients]; -8.1 mm Hg [95% confidence interval {CI}, -10.2 to -5.9]/-3.8 mm Hg [95% CI,-5.3 to -2.3]); total cholesterol (9 studies [1121 patients]; -17.4 mg/L [95% CI,-25.5 to -9.2]), low-density lipoprotein cholesterol (7 studies [924 patients]; -13.4 mg/L [95% CI,-23.0 to -3.8]), and a reduction in the risk of smoking (2 studies [196 patients]; relative risk, 0.77 [95% CI, 0.67 to 0.89]). While most studies tended to favor pharmacist care compared with usual care, a substantial heterogeneity was observed. CONCLUSION: Pharmacist-directed care or in collaboration with physicians or nurses improve the management of major CVD risk factors in outpatients.

Impact of recommendation updates in well-controlled patients on nonrecommended antiretroviral therapies: the Swiss HIV cohort study.

BACKGROUND: HIV treatment recommendations are updated as clinical trials are published. Whether recommendations drive clinicians to change antiretroviral therapy in well-controlled patients is unexplored. METHODS: We selected patients with undetectable viral loads (VLs) on nonrecommended regimens containing double-boosted protease inhibitors (DBPIs), triple-nucleoside reverse transcriptase inhibitors (NRTIs), or didanosine (ddI) plus stavudine (d4T) at publication of the 2006 International AIDS Society recommendations. We compared demographic and clinical characteristics with those of control patients with undetectable VL not on these regimens and examined clinical outcome and reasons for treatment modification. RESULTS: At inclusion, 104 patients were in the DBPI group, 436 in the triple-NRTI group, and 19 in the ddI/d4T group. By 2010, 28 (29%), 204 (52%), and 1 (5%) patient were still on DBPIs, triple-NRTIs, and ddI plus d4T, respectively. 'Physician decision,' excluding toxicity/virological failure, drove 30% of treatment changes. Predictors of recommendation nonobservance included female sex [adjusted odds ratio (aOR) 2.69, 95% confidence interval (CI) 1 to 7.26; P = 0.01] for DPBIs, and undetectable VL (aOR 3.53, 95% CI 1.6 to 7.8; P = 0.002) and lack of cardiovascular events (aOR 2.93, 95% CI 1.23 to 6.97; P = 0.02) for triple-NRTIs. All patients on DBPIs with documented diabetes or a cardiovascular event changed treatment. Recommendation observance resulted in lower cholesterol values in the DBPI group (P = 0.06), and more patients having undetectable VL (P = 0.02) in the triple-NRTI group. CONCLUSION: The physician's decision is the main factor driving change from nonrecommended to recommended regimens, whereas virological suppression is associated with not switching. Positive clinical outcomes observed postswitch underline the importance of observing recommendations, even in well-controlled patients.

The interface between oral and systemic health: the need for more collaboration.

The focus of this review is to highlight the need for improved communication between medical and dental professionals in order to deliver more effective care to patients. The need for communication is increasingly required to capitalise on recent advances in the biological sciences and in medicine for the management of patients with chronic diseases. Improvements in longevity have resulted in populations with increasing special oral-care needs, including those who have cancer of the head and neck, those who are immunocompromised due to HIV/AIDS, advanced age, residence in long-term care facilities or the presence of life-long conditions, and those who are receiving long-term prescription medications for chronic conditions (e.g., anti-hypertensives, anticoagulants, immunosuppressants, antidepressants). These medications can cause adverse reactions in the oral cavity, such as xerostomia and ulceration. Patients with xerostomia are at increased risk of tooth decay, periodontal disease and infection. The ideal management of such individuals should involve the collaborative efforts of physicians, nurses, dentists and dental hygienists, thus optimising treatment and minimising secondary complications deriving from the oral cavity.

Mieux contrôler les facteurs de risque des maladies cardiovasculaires grâce au pharmacien

Le pharmacien - seul ou en collaboration avec d'autres professionnels de soins - peut permettre de mieux contrôler les facteurs de risque des maladies cardiovasculaires (MCV) tels que l'hypertension, l'hypercholestérolémie ou le tabagisme. C'est la conclusion d'une récente revue systématique parue dans les Archives of Internal Medicine, réalisée par le Dr Valérie Santschi, pharmacienne, PhD et ses collègues de l'Université McGill de Montréal et de l'Institut universitaire de médecine sociale et préventive (IUMSP) du Centre Hospitalier Universitaire Vaudois (CHUV) de Lausanne. Cette revue systématique indique qu'il est pertinent d'intégrer plus systématiquement le pharmacien dans la prévention et la prise en charge des MCV. [Ed.]

Lessons learned from developing a national NCD programme in low- and middle-income countries (Seychelles)

This paper identifies selected issues and lessons learned from the implementation of a national program of prevention and control of non-communicable diseases (NCD) during the past 20 years in the Seychelles, a small island state in the African region. As early as in 1989, population-based surveys demonstrated high levels of several cardiovascular risk factors, which prompted an organized response by the government. The early creation of a NCD unit within the Ministry of Health, coupled with cooperation with international partners, enabled incremental capacity building and coherent development of NCD programs and policy. Information campaigns and screening for hypertension and diabetes in work/public places raised awareness and rallied increasingly broad awareness and support to NCD prevention and control. A variety of interventions were organized for tobacco control and comprehensive tobacco control legislation was enacted in 2009 (including total bans on tobacco advertising and on smoking in all enclosed public and work places). A recent School Nutrition Policy prohibits the sale of soft drinks in schools. At primary health care level, guidelines were developed for the management of hypertension and diabetes (these conditions are managed in all health centers within a national health system); regular interactive education sessions were organized for groups of high risk patients ("heart health club"); and specialized "NCD nurses" were trained. Decreasing prevalence of smoking is evidence of success, but the raising "diabesity epidemic" calls for strengthened health care to high-risk patients and broader multisectoral policy to mould an environment conducive to healthy behaviors. Key components of NCD prevention and control in Seychelles include effective surveillance mechanisms supplemented by focused research; generating broad interest and consensus on the need for prevention and control of NCD; mobilizing leadership and commitment at all levels; involving local and international expertise; building on existing efforts; and seeking integrated, multi-disciplinary and multisectoral approaches.
