The Effects of Mindfulness and Self-Compassion on Improving the Capacity to Adapt to Stress Situations in Elderly People Living in the Community

ABSTRACT

Objectives: This study aimed to show the effectiveness of mindfulness and self-compassion therapy in improving coping ability and adaptation to stressful situations in the elderly.Methods: Forty-five elderly non-institutionalized adults were randomized to either treatment or a treatment waiting list. A pre- and post-treatment assessment was performed, consisting of the Brief Resilient Coping Scale (BRCS), Depression Anxiety Stress Scales (DASS), and Coping Strategies Questionnaire. The program was developed over 10 sessions lasting 120 minutes each.Results: Analysis of variance for repeated measures showed significant differences in the time-group interaction for the treatment’s effectiveness in improving resilience, positive reappraisal and avoidance strategies, and decreasing anxiety, problem-solving coping, negative self-focus, overt emotional expression and religion.Conclusions: The mindfulness and self-compassion program is useful for improving resilience and coping strategies and reducing anxiety and stress levels in the elderly.     

Is the “farm effect” hypothesis still current? Atopy and allergic diseases in rural and urban children in Poland

Objective: The prevalence of allergic diseases has reached epidemic proportions in the Western world. Although farm-living has been associated with a lower prevalence of asthma and atopy, a marked increase in atopy among rural populations after accession to the European Union has been recently reported in Poland. Here, we aimed to investigate the effect of living environment on the prevalence of atopy and allergic diseases in Polish children. Methods: 400 schoolchildren aged 10–14 years from the capital city (223) and from traditional rural part of the country (177) were recruited from June to November 2011. Data on allergic diseases and symptoms were collected by means of questionnaire and physical examination. Atopy was assessed based on skin prick tests (SPTs) reactivity to inhalant allergens in 350 children. Results: A high discrepancy between the prevalence of allergic symptoms (46.7%) and doctor-diagnosed allergic diseases (25%) was demonstrated (p < 0.0001). Urban children had a higher overall prevalence of allergic diseases and atopy than children living in rural areas, 29.3% versus 17.1% (p = 0.007) and 33.5% versus 20% (p = 0.0045), respectively. However, no significant differences in the rates of particular allergic diseases were noted (p > 0.05). There was higher SPT positivity to trees, grass, corn, weeds, animal dander, and molds in urban children (p < 0.05). Conclusions: Our data support the protective effect of farm-living on the prevalence of atopy and overall allergic diseases, albeit not on particular allergic diseases, in children in Poland. The underlying mechanisms are not identified, but current socioeconomic changes may be responsible.     

Trends in bacterial resistance in a tertiary university hospital over one decade

The objective of this study was to investigate bacterial resistance trends, infection sites and the relationship between resistance and admittance to the intensive care unit (ICU). A total of 53,316 bacteria identified between 1999 and 2008 were evaluated. Multidrug resistance was characterized when gram-negative bacilli (GNB) presented resistance to two or more classes of antibiotics. Gram-positive cocci (CPC) were assessed for resistance to penicillin, oxacillin and vancomycin. GNB were the most common (66.1%) isolate. There was a 3.7-fold overall increase in multidrug resistant GNB over the study period; Acinetobacter baumanii and Staphylococcus aureus were the most prevalent. Highest increases were recorded for Klebsiella pneumoniae (14.6-fold) and enterococci (73-fold). The resistance rates for GNB and GPC were 36% and 51.7%, respectively. Most multidrug resistant GNB and GPC were recovered from ICU patients (p-value < 0.001). Vancomycin-resistant enterococci were isolated during this decade with an increase of 18.7% by 2008. These data confirm the worldwide trend in multidrug bacterial resistance.     

Antioxidant and Anticlastogenic Capacity of Prickly Pear Juice

Plants belonging to the genus Opuntia spp. are the most abundant of the Cactaceae family, grown throughout America and the Mediterranean central area. Its fruit, known as cactus pear or prickly pear, is an oval berry grouped in different colors. Some studies have shown its antioxidant activities which may help in preventing chronic pathologies such as diabetes. The purpose of the study was to evaluate the antioxidant capacity of three varieties of prickly pear juice (red-purple, white-green and yellow-orange) in five different concentrations (100, 250, 500, 750, and 1000 mg/mL) by DPPH (1,1-diphenyl-2-picrylhydrazyl radical) colorimetric method, selecting the best variety to determine its anticlastogenic potential against methyl methanesulfonate (MMS). The results indicate that the highest antioxidant was found in the juice of the prickly pear red-purple variety (PPRP), in all concentrations. Its anticlastogenic potential was therefore evaluated with a micronucleus assay. The experiment was run over two weeks. A negative control was included along with a positive control with MMS (40 mg/kg), a group of mice treated with PPRP (25 mL/kg), and three groups with PPRP (in doses of 25, 16.5 and 8.3 mL/kg) plus the mutagen. The PPRP was administered daily by oral gavage and the MMS was injected intraperitoneally five days prior to the end of the experiment. Blood samples were obtained at 0, 24, 48, 72 and 96 h in order to determine the frequency of micronucleated polychromatic erythrocytes (MNPE). The results indicated that PPRP is not a genotoxic agent, on the contrary, it may reduce the number of MNPE. In this regard, the PPRP showed an anticlastogenic effect directly proportional to its concentrations. Thus, the highest protection was obtained with a concentration of 25 mL/kg after 48 h of treatment.     

Measurement of Mercury in Human Hair

Measurements of total and inorganic mercury in human hair were used to trace the history and extent of methyl mercury exposures. Data on the distribution of mercury in hair were converted by a mathematical model into information about the key indices of exposure, including times of onset and termination, peak concentration in hair, and half-time of retention in blood. The model was used for computer simulations of the true distribution of mercury in hair and was validated by analyses of segments of single hairs. Conventional methods of hair sampling and fitting the resulting data to a curve were shown to introduce systematic errors underestimating peak concentrations and overestimating retention times. These errors were minimized by practical modification of the hair sampling procedures and by a new graphic method for deriving the measurements of distribution of the trace element in hair.     

Síntomas relacionados con el climaterio en mujeres residentes en la provincia de Zaragoza

ObjetiveThe aim of this study was to assess menopausal symptoms and related sociodemographic conditions in middle-aged women from the Spanish province of Zaragoza.MethodThis was a cross-sectional study in which 241 women (40-59 years old) from the Zaragoza province completed the Menopause Rating Scale (MRS) and a sociodemographic questionnaire containing personal and partner data to assess symptoms associated with the menopause.ResultsThe most prevalent symptoms were musculoskeletal, followed by hot flushes and perspiration. Somatic, psychological and urogenital symptoms were more severe in post-menopausal women. Somatic and urogenital symptoms worsen with age, body mass index, age at menopause, and partner age. Multiple linear regression analysis (MA) for somatic symptoms was related with the menopausal status, psychiatric treatment, problems with sexual relationships, and history of gender violence. The MA for psychological symptoms was associated with menopausal status, psychiatric treatment and a history of gender violence. The MA for urogenital symptoms was associated with menopausal status, problems with sexual relationships, urinary incontinence and partner alcohol abuse. A history of gender violence was reported by 11.6% of the women.ConclusionIn this sample of middle-aged women, menopausal symptoms were related to menopausal status, and other factors associated with their partner factors, including gender violence.     

Evaluation of Reduced Susceptibility to Quaternary Ammonium Compounds and Bisbiguanides in Clinical Isolates and Laboratory-Generated Mutants of Staphylococcus aureus

The MICs and minimum bactericidal concentrations (MBCs) for the biocides benzalkonium chloride and chlorhexidine were determined against 1,602 clinical isolates of Staphylococcus aureus. Both compounds showed unimodal MIC and MBC distributions (2 and 4 or 8 mg/liter, respectively) with no apparent subpopulation with reduced susceptibility. To investigate further, all isolates were screened for qac genes, and 39 of these also had the promoter region of the NorA multidrug-resistant (MDR) efflux pump sequenced. The presence of qacA, qacB, qacC, and qacG genes increased the mode MIC, but not MBC, to benzalkonium chloride, while only qacA and qacB increased the chlorhexidine mode MIC. Isolates with a wild-type norA promoter or mutations in the norA promoter had similar biocide MIC distributions; notably, not all clinical isolates with norA mutations were resistant to fluoroquinolones. In vitro efflux mutants could be readily selected with ethidium bromide and acriflavine. Multiple passages were necessary to select mutants with biocides, but these mutants showed phenotypes comparable to those of mutants selected by dyes. All mutants showed changes in the promoter region of norA, but these were distinct from this region of the clinical isolates. Still, none of the in vitro mutants displayed fitness defects in a killing assay in Galleria mellonella larvae. In conclusion, our data provide an in-depth comparative overview on efflux in S. aureus mutants and clinical isolates, showing also that plasmid-encoded efflux pumps did not affect bactericidal activity of biocides. In addition, current in vitro tests appear not to be suitable for predicting levels of resistance that are clinically relevant.
