Hormone profiles, body mass index and aging male symptoms: results of the Androx Vienna Municipality study

Aging in the male is accompanied by steroid hormonal decline, and men may develop symptoms associated with hypogonadism. Increased awareness of ‘andropause’ in recent years has led to greater demand for hormonal assessments, resulting in a rising burden for health economics. We conducted a cross-sectional study to define men at risk for hypogonadism, in whom further hormonal investigation should be performed. We examined 664 blue-collar workers aged 40–60 years at their workplace and determined hormonal status and body mass index (BMI). Men with an abnormal urogenital status and those on medication that might affect endocrine status were excluded from the study. All participants completed the validated Aging Male Symptom (AMS) questionnaire and obtained scores for psychological symptoms, somatovegetative symptoms, and sexual symptoms. Multiple logistic regression analyses revealed a significantly increased risk (represented by the odds ratio) of psychological symptoms for men with low levels of testosterone and/or bioavailable testosterone (BAT). Increased BMI as well as low testosterone levels and/or low BAT levels raised the risk of somatovegetative symptoms. Each decrease of BAT by 1 ng/ml caused an approximately 1.8-fold increase of the risk (odds ratio = 1.832, p = 0.005). Additional independent risk factors were increased age and low luteinizing hormone (LH) level. Men aged 55 years with BMI > 28 kg/m2 and with somatovegetative symptoms and moderate or severe psychological symptoms had a 7.2-fold increase in the risk of a BAT level < 1.5 ng/ml compared to men without these risk factors (p < 0.001). Sensitivity and specificity were 75% and 71%, respectively. The AMS score combined with age and BMI provides an easy and convenient method to identify men with probable androgen deficiency who require hormonal assessment.
[Smoking and colorectal cancer risk in the Korean elderly].

OBJECTIVES The incidence of colorectal cancer increased greatly among the elderly in Korea, but the relationship between smoking and colon cancer remains controversial. Few studies have targeted Asian elderly people. We analyzed the smoking status, the amount smoked, and the smoking duration as risk factors of colorectal cancer to determine their association and causality. METHODS The cohort members (n = 14,103) consisted of 4,694 males and 9,409 females, and they were derived from the Korea Elderly Phamacepidemilogic Cohort (KEPEC), which was a population-based dynamic cohort. They were aged 65 years or more and they lived in Busan Metropolitan City between from 1993-1998; they were beneficiaries of the Korean Medical Insurance Corporation (KMIC). The baseline information was surveyed by a self-administered mailed questionnaire; after 8.7 person-years of mean follow up period, 100 cases of colorectal cancer occurred. The adjusted relative ratio (aRR) of smoking status, the smoking amount and the smoking duration were calculated from the Cox's proportional hazard model with the never-smokers as a reference group and the Cox model controlled for age, gender, precancerous lesions of CRC, medication history of NSAIDs and antibiotics, the alcohol drinking status and BMI. RESULTS Compared with the never smokers, the aRRs were 2.03 (95% CI = 1.02-4.03) and 1.36 (95% CI = 0.80-2.32) for the ex-smokers and current smokers, respectively. Statistical significant trends were not observed for the dose-relationship among the elderly, either for the mean daily amount smoked (p for trend = 0.28) or for the total amount (p for trend = 0.15). Still, the aRRs were 1.51 (95% Cl = 0.97-2.34) for the elderly who smoked less than 40 years and 2.35 (95% CI = 1.16-4.74) for the elderly who had 40 years or more of smoking (p for trend = 0.06). Smokers who started smoking before the age 20 had an increased aRR of 2.15 (95% CI = 1.17-3.93) compared to the never smokers. CONCLUSIONS After controlling for age, gender, precancerous lesion of CRC, medication history of NSAIDs and antibiotics, the alcohol drinking status and BMI, smoking increases the risk of colorectal cancer among elderly people. The age when starting smoking is also important.
Progression of joint damage in early rheumatoid arthritis: association with HLA-DRB1, rheumatoid factor, and anti-citrullinated protein antibodies in relation to different treatment strategies.

OBJECTIVE To determine the association of HLA-DRB1, rheumatoid factor (RF), and anti-citrullinated protein antibody (ACPA) status with progression of joint damage in early rheumatoid arthritis (RA) treated according to different treatment strategies. METHODS The present study was conducted using data from the BeSt study (Behandelstrategieën voor Reumatoide Artritis [treatment strategies for rheumatoid arthritis]), a randomized trial comparing 4 targeted (toward achievement of a Disease Activity Score [DAS] of < or =2.4) treatment strategies: sequential monotherapy (group 1), step-up combination therapy (group 2), initial combination therapy with methotrexate, sulfasalazine, and prednisone (group 3), and initial combination therapy with methotrexate and infliximab (group 4), in 508 patients with early RA. Multivariate logistic regression analysis was used to predict progressive disease (increase of Sharp/van der Heijde score over 2 years beyond the smallest detectable change [4.6]) according to the presence or absence of the shared epitope (SE), DERAA, RF, and ACPA, with correction for other baseline characteristics. RESULTS Progressive disease could not be predicted by presence of the SE: the odds ratio in groups 1, 2, 3, and 4, respectively, was 1.4, 2.6, 1.9, and 3.0. DERAA carriership did not protect against progressive disease (odds ratio 0.4, 1.4, 0.9, and 0.9 in groups 1, 2, 3, and 4, respectively). RF positivity and ACPA positivity predicted progressive disease in group 1 (odds ratio 4.7 [95% confidence interval 1.5-14.5] for RF and 12.6 [95% confidence interval 3.0-51.9] for ACPA), but not in groups 2-4 (for RF, odds ratio [95% confidence interval] 1.5 [0.5-4.9], 1.0 [0.3-3.3], and 1.4 [0.4-4.8] in group 2, group 3, and group 4, respectively; for ACPA, odds ratio [95% confidence interval] 3.4 [0.8-14.2], 1.7 [0.5-5.4], and 1.8 [0.5-6.8] in group 2, group 3, and group 4). CONCLUSION In patients with early RA treated with the goal of tight control of the DAS, no significant association between HLA-DRB1 status and radiographic progression was found. RF and ACPA were predictive of progressive disease only in patients treated with sequential monotherapy. These observations suggest that effective treatment can prevent radiographic progression, even in patients with risk factors for severe damage.
Effect of method of administration of psyllium on glycemic response and carbohydrate digestibility.

To determine whether there was any advantage to taking a soluble fiber supplement separate from food, as opposed to incorporated into a food, we used psyllium as a model, either taken in water just before a flaked bran cereal test meal, sprinkled on top of the cereal, or actually incorporated into the flake. In normal subjects, psyllium reduced the glycemic response when sprinkled onto or incorporated into the cereal, but not when taken before the cereal. Varying the amount of psyllium incorporated into the cereal from 0 to 20% resulted in a linear dose-dependent reduction of the glycemic index (GI) (GI = 101 -2.2 x % psyllium; r = 0.950; p less than 0.002). In subjects with diabetes, the blood-glucose-lowering effect of the psyllium flake cereal was similar to that in normal subjects. Mixing psyllium with the cereal or incorporating it into the cereal reduced the rate of digestion of bran flakes in vitro but was not associated with increased breath hydrogen levels in vivo as an index of rapid colonic fermentation. The bran flakes with psyllium incorporated was rated as no less palatable than the bran flakes cereal alone, and significantly more palatable (p less than 0.05) than taking psyllium in water before the cereal or sprinkling psyllium onto the cereal. These studies confirm earlier reports that viscous fibers must be intimately mixed with the food to have the effect of reducing blood glucose responses, and that the mechanism of action relates to a reduced rate of digestion rather than carbohydrate malabsorption.

Digestive development of the early-weaned pig

Gastric intubation was adopted to examine the effect of continuous nutrient supply on digestive development of the pig during the immediate post-weaning period. The 14 d-weaned animals were slaughtered at 3, 5 and 7 d post-weaning (3W, 5W and 7W respectively) and the suckled animals were slaughtered at 14 and 22 d of age (14SR and 22SR respectively). The weight of the pancreas (g/kg body-weight) was significantly greater (P < 0.05) in the 5W and 7W groups, as was the weight of large intestine (g/kg) in all weaned groups (P < 0.01) compared with sow-reared pigs. The stomach weight (g/kg) tended to be greater in the weaned groups. Weaning, in conjunction with a continuous nutrient supply, did not significantly alter the time-related changes in the weight of the small intestine (SI) or the SI mucosa, although both variables tended to be lowest in the 3W group. However, there was a 20% reduction in the protein content of the mucosa within the first 3 d post-weaning (P < 0.01) which persisted during the 7 d experimental period. Lactase, (β-galactosidase; EC 3.2.1.23) activity (μmol/g protein and mol/d) of the 7W group was reduced to approximately 40% of the 22SR value. Hence, continuous nutrient supply may have delayed, but did not prevent, the loss of lactase activity at weaning. The activity of sucrase (sucrose-α-glucosidase; EC 3.2.1.48) was significantly higher in 22SR compared with 14SR animals. Sucrase activity in weaned pigs was intermediate to the values for sow-reared pigs whereas maltase (α-glucosidase; EC 3.2.1.20) and glucoamylase (glucan 1, 4-α-glucosidase; EC 3.2.1.3) were significantly increased in relation to their sow-reared counterparts. Continuous nutrient supply did not prevent the reduction in villous height and the crypt hypertrophy associated with weaning. The results of the present study suggest that there may be some degree of interaction between nutrient intake and gut development during the immediate post-weaning period but that there is also a component of the adaptive response which is independent of nutrient intake. They confirm the rapid substrate induction of the brush-border glucoamylases and indicate the importance of considering total as well as specific enzyme activity for satisfactory interpretation of changes in digestive function.
Lactobacillus reuteri Strain Combination In Helicobacter pylori Infection: A Randomized, Double-Blind, Placebo-Controlled Study

Goals: The goals of this study were to investigate the role of a new probiotic preparation (Lactobacillus reuteri DSM 17938 and L. reuteri ATCC PTA 6475) in Helicobacter pylori infection. Background: Specific probiotic strains play a role in H. pylori infection for their ability to decrease bacterial load and gastritis, prevent antibiotic-associated side effects, and increase the eradication rate. Study: This is a prospective, double-blind, randomized, placebo-controlled study in a tertiary care setting. A total of 100 H. pylori–positive naive patients received either L. reuteri combination (2×108 Colony Forming Units) or placebo during a 3-phase study (pre-eradication, eradication, and follow-up). All underwent 13C urea breath test (13C-UBT), blood assessments of gastrin-17 (G17), endoscopy, and the Gastrointestinal Symptom Rating Scale. Eradication was confirmed by 13C-UBT 8 weeks after the completion of therapy. Results: Fifty patients were allocated in each group. During pre-eradication period, 13C-UBT &dgr; decreased by 13% in L. reuteri combination as compared with a 4% increase in placebo (−13.2±34% vs. 4.3±27%; P<0.03). During eradication, GSRS increased significantly in placebo as compared with L. reuteri combination (6.8±2.9 vs. 4±3.1; P<0.01). Significantly less patients in L. reuteri combination as compared with placebo-reported side effects (40.9% vs. 62.8%; P<0.04). An abnormal G17 value was found in patients receiving placebo as compared with L. reuteri combination (28% vs. 12%; P<0.02). Eradication rate was 75% in L. reuteri combination and 65.9% in placebo (P=NS). L. reuteri combination increased eradication rate by 9.1% (odds ratio: 1.5). Conclusions: L. reuteri combination alone is able to exert an inhibitory effect on H. pylori growth, and when administered with eradication therapy, it determines a significant reduction in antibiotic-associated side effects. Moreover, L. reuteri combination was able to decrease serum G17 levels and to (not significantly) increase the H. pylori–eradication rate.
Development and validation of the Caregiver Guilt Questionnaire

ABSTRACT Background: Family care of frail elderly people has been linked to significant negative consequences for caregivers' mental health. Although outcome variables such as burden and depression have been widely analyzed in this population, guilt, an emotion frequently observed in caregivers, has not received sufficient attention in the research literature. Methods: Face-to-face interviews were carried out with 288 dementia caregivers. Guilt was measured using the Caregiver Guilt Questionnaire (CGQ). Results: Using principal components analysis, 22 items were retained and five factors were obtained which explained 59.25% of the variance. These factors were labeled: guilt about doing wrong by the care recipient, guilt about not rising to the occasion as caregivers, guilt about self-care, guilt about neglecting other relatives, and guilt about having negative feelings towards other people. Acceptable reliability indexes were found, and significant associations between the CGQ and its factors and the Zarit Burden Interview guilt factor were also found. Caregivers with higher scores on the CGQ also scored higher in depression, anxiety, frequency and appraisal of behavioral problems. Negative associations between the CGQ and its factors and frequency of/and satisfaction with leisure and social support were also found. Being female and caring for a parent were associated with higher scores on the CGQ. Conclusions: Feelings of guilt are significantly related to caregiver distress. The CGQ may be a useful measure for acknowledging feelings of guilt in caregivers; moreover, it can be used as an outcome variable for psychoeducational interventions aimed at reducing caregiver distress.
A new scale for the measurement of interpersonal trust.

One of the most salient factors m the effecdveness of our present complex social organization is the willmgness of one or more mdividuals m a social unit to trust others The efficiency, adjustment, and even survival of any social group depends upon the presence or absence of such trust. Interpersonal tmst is defined here as an expectancy held by an mdividual or a group that the word, promise, verbal or wntten statement of another individual or group can be relied upon. This definition clearly departs significandy from Enkson's (1953) broad use of the concept of basic trust which Enkson descnbes as a central ingredient m "the healthy personality " Vanous wnters have already mdicated that a high expectancy that others can be relied upon is an important variable in the development of adequate family relationships and of healthy personahties in children The fadure to tmst others, particularly representatives of society, such as parents, teachers, and powerful commumty leaders, has frequently been cited as an important determmant m delmquency (Redl & Wmeman, 1951) Difficuldes m race relationships and m mmonty group-majonty group relationships have, likewise, been frequently related to expectancies of one group that the verbal statements of the other cannot be accepted Many psychotherapists believe interpersonal tmst is a major determinant in the success of psychotherapy In fact, an expectancy that others can be believed must be an important variable m human learmng in general Much of the formal and informal leaming that human bemgs acquire is based on the verbal and wntten statements of others, and what they leam must be significandy affected by the degree to which they believe their informants without independent evidence.

Se presenta una sintesis de informacion etnobiologica obtenida entre grupos indigenas de Mexico, analizando tendencias y patrones en las formas de conocer, utilizar y manipular los recursos biologicos. Los sistemas indigenas de nomenclatura y clasificacion de plantas son altamente elaborados y complejos. Aunque en general estos parecen seguir los principios generales de clasificacion folk descubiertos por Brent Berlin y otros autores, se observan algunas categorias taxonomicas y sistemas de nomenclatura estrechamente asociados a las formas de uso de los recursos locales. La subsistencia de las poblaciones indigenas ha estado basada en una estrategia que combina diferentes practicas productivas y que aprovecha una gran diversidad de productos disponibles tanto espacial como temporalmente. Esta estrategia involucra tambien el aprovechamiento integral de un amplio espectro de especies de plantas y variabilidad genetica intraespecifica bajo diferentes niveles de domesticacion.ABSTRACTAn overview of ethnobiological information obtained among Indian peoples of Mexico is presented, analyzing patterns and tendencies in the forms of perceiving, using, and manipulating plant resources. The plant classification folk systems studied are highly complex. Although in general they follow the general principles formulated by Brent Berlin and other scholars, some significant variations are observed. Subsistence has been based on a strategy which combines different productive activities and takes advantage of a wide variety of plant products available both in time and space. This subsistence strategy also involves managing a wide variety of resources under different degrees of domestication by humans.
The Maternal Gut Microbiome During Pregnancy

Abstract The gut microbiome is a critical component of an individual's metabolism and overall health. The prenatal period is marked by unique inflammatory and immune changes that alter maternal gut function and bacterial composition as the pregnancy advances. The composition of the maternal gut microbiome contributes to obstetric outcomes with long-term health sequelae for mother and child. Estrogen and progesterone also have an impact on gut function, especially during the prenatal period. These physiologic changes in pregnancy allow for adjustments in maternal metabolism and weight necessary to support the pregnancy. Normal hormonal, metabolic, and immunologic changes to the maternal gut microbiome throughout the prenatal period are reviewed, including relevant implications for nurses providing care for pregnant women.
Cytochrome P450 1B1 Is Overexpressed and Regulated by Hypomethylation in Prostate Cancer

Purpose: Cytochrome P450 1B1 (CYP1B1), a dioxin inducible member of the CYP supergene family, is overexpressed in various human malignancies including prostate cancer. We hypothesized that promoter/enhancer CpG methylation contributes to the regulation of CYP1B1 expression in human prostate tissue. Experimental Design: Expression and induction of the CYP1B1 gene in clinical prostate tissues and prostate cancer cell lines were investigated. The methylation status of the CYP1B1 gene was analyzed in 175 prostate cancer and 96 benign prostatic hyperplasia samples using methylation-specific PCR (MSP) and bisulfite-modified DNA sequencing. MSP primers covered dioxin response elements (DRE) and Sp1 sites that are important for the expression of CYP1B1. Results: Expressions of CYP1B1 mRNA and protein were increased in prostate cancer. The aryl hydrocarbon receptor (AhR)/AhR nuclear translocator (ARNT) heterodimer complex activates gene transcription by binding to the DREs of CYP1B1. In prostate cancer cells, CYP1B1 mRNA was induced by 2,3,7,8-tetrachlorodigenzo-p-dioxin (TCDD) and/or demethylation agent (5-aza-2-deoxycytidine). There was no change in the expressions of AhR and ARNT. Methylation of promoter/enhancer regions was significantly higher in benign prostatic hyperplasia compared with prostate cancer. MSP-positive patients had significantly lower risk for prostate cancer as compared with MSP-negative patients. There was no correlation between CYP1B1 methylation status and clinicopathologic features. Conclusions: CYP1B1 is overexpressed in prostate cancer and regulated by hypomethylation of its promoter/enhancer region. This is the first report about CYP1B1 regulation in human clinical prostate samples showing that hypomethylation of the CYP1B1 gene may play an important role in prostate cancer.
Probing mechanical principles of focal contacts in cell–matrix adhesion with a coupled stochastic–elastic modelling framework

Cell–matrix adhesion depends on the collective behaviours of clusters of receptor–ligand bonds called focal contacts between cell and extracellular matrix. While the behaviour of a single molecular bond is governed by statistical mechanics at the molecular scale, continuum mechanics should be valid at a larger scale. This paper presents an overview of a series of recent theoretical studies aimed at probing the basic mechanical principles of focal contacts in cell–matrix adhesion via stochastic–elastic models in which stochastic descriptions of molecular bonds and elastic descriptions of interfacial traction–separation are unified in a single modelling framework. The intention here is to illustrate these principles using simple analytical and numerical models. The aim of the discussions is to provide possible clues to the following questions: why does the size of focal adhesions (FAs) fall into a narrow range around the micrometre scale? How can cells sense and respond to substrates of varied stiffness via FAs? How do the magnitude and orientation of mechanical forces affect the binding dynamics of FAs? The effects of cluster size, cell–matrix elastic modulus, loading direction and cytoskeletal pretension on the lifetime of FA clusters have been investigated by theoretical arguments as well as Monte Carlo numerical simulations, with results showing that intermediate adhesion size, stiff substrate, cytoskeleton stiffening, low-angle pulling and moderate cytoskeletal pretension are factors that contribute to stable FAs. From a mechanistic point of view, these results provide possible explanations for a wide range of experimental observations and suggest multiple mechanisms by which cells can actively control adhesion and de-adhesion via cytoskeletal contractile machinery in response to mechanical properties of their surroundings.
