Association of Endogenous Hormones and Bone Mineral Density in Postmenopausal Women.

Aim: The aim of this study was to examine the association between endogenous hormones and bone mineral density (BMD) in postmenopausal women. Materials and Methods: This was a cross-sectional study of 798 postmenopausal women aged 47-85 years. Data were collected on age, age at menopause, years since menopause, smoking status, body mass index, adiposity, BMD, physical activity, and Vitamin D supplementation. Measured hormonal parameters were: follicle-stimulating hormone (FSH), estradiol, testosterone, dehydroepiandrosterone sulfate, ∆4-androstenedione, cortisol, insulin-like growth factor-1, 25-hydroxyvitamin D, and parathormone (PTH) levels. BMD was measured at the lumbar spine, femoral neck, and total hip using dual-energy X-ray absorptiometry. A directed acyclic graph was used to select potential confounding variables. Results: Multivariable analysis showed significant associations between cortisol and femoral neck BMD (ß: -0.02, 95% confidence interval [CI]: -0.03--0.00), and PTH with femoral neck BMD (ß: -0.01, 95% CI: -0.02--0.01) and total hip BMD (ß: -0.01, 95% CI: -0.01--0.00). Hormonal factors more likely associated with a higher risk of low BMD (osteopenia or osteoporosis) were FSH (odds ratio [OR]: 1.02, 95% CI: 1.01-1.03) and PTH (OR: 1.02, 95% CI: 1.01-1.04). Conclusions: Higher cortisol and PTH levels were inversely associated with BMD. Postmenopausal women with higher FSH or PTH levels were likely to have low BMD.

Advances in Imaging for Assessing Pelvic Endometriosis.

In recent years, due to the development of standardized diagnostic protocols associated with an improvement in the associated technology, the diagnosis of pelvic endometriosis using imaging is becoming a reality. In particular, transvaginal ultrasound and magnetic resonance are today the two imaging techniques that can accurately identify the majority of the phenotypes of endometriosis. This review focuses not only on these most common imaging modalities but also on some additional radiological techniques that were proposed for rectosigmoid colon endometriosis, such as double-contrast barium enema, rectal endoscopic ultrasonography, multidetector computed tomography enema, computed tomography colonography and positron emission tomography-computed tomography with 16α-[18F]fluoro-17ß-estradiol.

Safety and Effectiveness of a Single Multiallergen Subcutaneous Immunotherapy in Polyallergic Patients.

BACKGROUND: As the number of allergic sensitizations increases the severity of allergic respiratory diseases worsens. Multiple monoallergen immunotherapy can be accompanied by poor treatment adherence and high costs, single multiallergen immunotherapy needs to prove efficacy whilst maintaining a good safety profile. METHODS: Observational, retrospective, multicenter study using a 2-pollen single undiluted multiallergen subcutaneous immunotherapy (SCIT) in routine clinical practice in Spain. Patients with rhinoconjunctivitis, with/without controlled asthma, sensitized to grass, olive, Parietaria, Cupressus, plane tree and/or Salsola pollen were included. Primary and secondary clinical efficacy endpoints were quality of life (mini Rhinitis Quality of Life Questionnaire (miniRQLQ)) and visual analogue scale (VAS) respectively. All adverse events were documented. RESULTS: Ten centers included 97 patients, median age 32 years. SCIT treatment included combinations of grass mix with olive, Parietaria, Cupressus, plane tree or Salsola or olive with Parietaria, Cupressus or Salsola. The mean duration of SCIT was 1.8 years with a high treatment adherence (73%). Significant improvement in quality of life, nasal and ocular symptoms, activity limitations and practical problems (p< 0.0001) and other symptoms (p= 0.024) was observed. Most patients did not develop asthma-like symptoms and a significant improvement of all allergic symptom severity was perceived. VAS showed a significant improvement in rhinoconjunctivitis and asthma by patients and physicians. Twenty-nine patients experienced adverse reactions, 25 had local and 6 had systemic reactions. CONCLUSIONS: Single undiluted multiallergen SCIT treatment of two different pollens is efficacious and safe in both children and adults, showing that it is a suitable option for the treatment of polyallergic patients.

Ketogenic Diet Decreases Alcohol Intake in Adult Male Mice.

The classic ketogenic diet is a diet high in fat, low in carbohydrates, and well-adjusted proteins. The reduction in glucose levels induces changes in the body's metabolism, since the main energy source happens to be ketone bodies. Recent studies have suggested that nutritional interventions may modulate drug addiction. The present work aimed to study the potential effects of a classic ketogenic diet in modulating alcohol consumption and its rewarding effects. Two groups of adult male mice were employed in this study, one exposed to a standard diet (SD, n = 15) and the other to a ketogenic diet (KD, n = 16). When a ketotic state was stable for 7 days, animals were exposed to the oral self-administration paradigm to evaluate the reinforcing and motivating effects of ethanol. Rt-PCR analyses were performed evaluating dopamine, adenosine, CB1, and Oprm gene expression. Our results showed that animals in a ketotic state displayed an overall decrease in ethanol consumption without changes in their motivation to drink. Gene expression analyses point to several alterations in the dopamine, adenosine, and cannabinoid systems. Our results suggest that nutritional interventions may be a useful complementary tool in treating alcohol-use disorders.

Evaluación del bienestar espiritual en pacientes en cuidados paliativos / Assessment of spiritual well-being in palliative care patients

OBJETIVO: La evaluación del bienestar espiritual del paciente es un aspecto crítico y fundamental en la atención holística y multidisciplinar. Disponer de un instrumento válido de evaluación de la espiritualidad con finalidad tanto investigadora como clínica es muy conveniente. En este estudio se examina la presencia de bienestar espiritual, o sentido de la vida, en pacientes en cuidados paliativos a través de un cuestionario con garantías psicométricas de calidad. PACIENTES Y MÉTODOS: Han participado en este estudio con diseño transversal un total de 60 pacientes en cuidados paliativos. El instrumento básico empleado ha sido la versión española del Cuestionario del Sentido de la Vida (Meaning in Life Scale), de 21 ítems y 4 escalas: Propósito, Falta de significado, Paz, y Beneficios de la espiritualidad. Se proporciona, también, una puntuación global de espiritualidad. Se registraron, además, variables de tipo clínico y sociodemográfico, así como estimaciones del estado de salud, calidad de vida (general y actual), felicidad personal, el grado de religiosidad y la creencia en la existencia de vida ultraterrena. RESULTADOS: Los resultados muestran que la versión española de este instrumento (Cuestionario del Sentido de la Vida [Meaning in Life Scale]) es una medida de bienestar espiritual con garantías psicométricas de calidad (buena fiabilidad y validez), adecuada para evaluar la complejas exigencias generadas por la enfermedad crónica del paciente en cuidados paliativos. El bienestar espiritual se relaciona significativamente con diversas variables de calidad de vida, percepción de salud, felicidad personal o religiosidad. No existe una relación significativa entre las puntuaciones de espiritualidad y variables sociodemográficas como la edad o el sexo. La presencia de bienestar espiritual en estos pacientes es más baja de la esperada. CONCLUSIÓN: Este cuestionario de espiritualidad resulta un instrumento válido para valorar las 4 dimensiones básicas del bienestar espiritual. Los resultados sugieren que considerar y evaluar el bienestar espiritual de los pacientes en cuidados paliativos puede ser de ayuda para la práctica clínica. La presencia de espiritualidad parece desempeñar un papel importante en el bienestar psicológico, el estado de salud y la calidad de vida percibidos por el paciente en cuidados paliativos. El grado de bienestar espiritual de estos pacientes es relativamente bajo

OBJECTIVE: Assessing spiritual well-being is an essential and critical aspect of holistic and multidisciplinary patient care practice. A valid assessment of spirituality is necessary for clinical and research purposes. This study examined the presence of spiritual well-being, or meaning in life, in palliative care patients using a psychometrically-sound questionnaire of spirituality. PATIENTS AND METHODS: A cross-sectional study was carried out with 60 palliative care patients. The main instrument, a Spanish-language version of the 21-item Meaning in Life Scale, comprises 4 scales: PURPOSE, Lessened Meaning, Peace, and Benefits of Spirituality. A total score for Spiritual well-being is also achieved. The following variables were also used: clinical, sociodemographic and assessments on self-rated health, quality of life (general and recently), personal happiness, religiosity, and belief in an afterlife. Results: Results of this study demonstrated that the Meaning in Life Scale is a psychometrically-sound measure of spiritual well-being for the palliative care patient (good reliability and validity), as they manage the complex demands of a chronic illness. Spiritual well-being was significantly associated with various quality of life variables, health status, personal happiness, or religiosity in patients on palliative care. No association was found between spirituality scores and sex or age. The presence of spiritual well-being in palliative care patients was lower than expected. CONCLUSION: This spirituality questionnaire is a valid instrument to assess 4 core dimensions of spiritual well-being. The results suggest that to address and assess spiritual well-being with palliative care patients may be helpful for clinical praxis. Spirituality may play an important role in the psychological well-being, quality of life, and self-rated health for palliative care patients. Spiritual well-being in these patients was relatively low

A relaxation technique enhances psychological well-being and immune parameters in elderly people from a nursing home: a randomized controlled study.

BACKGROUND: The aging process involves a decline in immune functioning that renders elderly people more vulnerable to disease. In residential programs for the aged, it is vital to diminish their risk of disease, promote their independence, and augment their psychological well-being and quality of life. METHODS: We performed a randomized controlled study, evaluating the ability of a relaxation technique based on Benson's relaxation response to enhance psychological well-being and modulate the immune parameters of elderly people living in a geriatric residence when compared to a waitlist control group. The study included a 2-week intervention period and a 3-month follow-up period. The main outcome variables were psychological well-being and quality of life, biomedical variables, immune changes from the pre-treatment to post-treatment and follow-up periods. RESULTS: Our findings reveal significant differences between the experimental and control groups in CD19, CD71, CD97, CD134, and CD137 lymphocyte subpopulations at the end of treatment. Furthermore, there was a decrease in negative affect, psychological discomfort, and symptom perception in the treatment group, which increased participants' quality of life scores at the three-month follow-up. CONCLUSIONS: This study represents a first approach to the application of a passive relaxation technique in residential programs for the elderly. The method appears to be effective in enhancing psychological well-being and modulating immune activity in a group of elderly people. This relaxation technique could be considered an option for achieving health benefits with a low cost for residential programs, but further studies using this technique in larger samples of older people are needed to confirm the trends observed in the present study.

Evaluation of percutaneous absorption of esculetin: effect of chemical enhancers.

Percutaneous transdermal absorption of esculetin (6,7-dihydroxycoumarin), an oxidative damage inhibitor, was evaluated by means of in vitro permeation studies in which vertical Franz-type diffusion cells and pig ear skin were employed. To determine the absorption of esculetin, we validated a simple, accurate, precise, and rapid HPLC-UV method. Additionally, the effects of several percutaneous enhancers were studied. Pretreatment of porcine skin was performed with ethanol (control vehicle), decenoic acid, oleic acid, R-(+)-limonene, and laurocapram (Azone®) (5% in ethanol, w/w, respectively). Pretreatment of skin with oleic acid or laurocapram led to statistically significant differences in the transdermal flux of esculetin with respect to controls. Of the two enhancers, laurocapram showed the greatest capacity to enhance the flux of esculetin across pig skin.

Effects of graded-release diltiazem versus ramipril, dosed at bedtime, on early morning blood pressure, heart rate, and the rate-pressure product.

BACKGROUND: Therapeutic agents for the treatment of hypertension may differ in their efficacy during the early morning period, a time when both morbid and mortal cardiovascular events are increased compared to other times of the day. METHODS: We studied the effects of a graded-release delivery system of diltiazem (diltiazem HCL extended release tablets) versus ramipril, both dosed at bedtime, on blood pressure (BP), heart rate, and the heart rate-systolic BP product during the first 4 hours after awakening in a double-blind, titration-to-effect trial. There were 261 men and women enrolled in the trial with an untreated sitting diastolic BP of 90 to 109 mm Hg and ambulatory daytime diastolic BP of 85 to 109 mm Hg. Patients were randomized to either diltiazem extended release (ER) tablets each evening (240 mg titrated to 360 mg and to 540 mg) or ramipril each evening (5 mg titrated to 10 mg and to 20 mg). Early morning assessments of BP, heart rate, and the heart rate-systolic BP product were performed using 24-hour ambulatory recordings after 10 weeks of therapy. RESULTS: In each therapeutic group, 76% of patients were titrated to the highest possible dose. After 10 weeks of treatment, reductions in early morning BP by diltiazem ER tablets were significantly greater (-18/-15 mm Hg) than reductions by ramipril (-13/-8 mmHg, P <.005 for systolic BP and P <.001 for diastolic BP). Diltiazem ER tablets also led to greater reductions in morning heart rate and the heart rate-pressure product compared to ramipril. Reductions in mean 24-hour diastolic BP, heart rate, and the rate-pressure product were greater in patients treated with diltiazem ER tablets compared to ramipril, while reductions in 24-hour systolic BP were similar in each group. The observed adverse effects were not serious and incidences were similar for the 2 treatment groups. CONCLUSIONS: These data demonstrate that bedtime administration of diltiazem ER, an agent designed to parallel the circadian rhythm of BP and heart rate, led to significantly greater early morning hemodynamic effects compared to the angiotensin-converting enzyme inhibitor ramipril, also dosed in the evening.
