Abstract Human health is multidomain. However, the physical component has dominated health research. Spiritual health, the component traditionally considered as the pivot for health and wellness has taken a back seat. Exploring its’ different determinants in the traditional preachers will enhance our understanding of them and will be a guide for their use in the common man’s life. Aim: To find out important sociocultural factors/drivers to the spiritual health in Indian Saints. Objectives: To identify the important social and cultural determinants of spirituality in the study group by factor extraction through Principal Component Analysis (PCA). Methodology: 958 connecting Indian Saints who congregated at Kumbh Mela at the holy city of Ujjain in 2016 were randomly selected in equal proportion from different sects(clans). Their sociocultural background and spiritual score were evaluated by a sociocultural questionnaire and SAI (Spiritual Assessment Inventory). The contribution of sociocultural factors to spiritual score was analysed by Principal Component Analysis (PCA) and linear regression modelling. Statistical significance was established at p < 0.05. Results: 20 sociocultural factors were evaluated for component loading (factor extraction) and their impact on the spiritual score. The KMO (Kaiser-Meyer-Olkin Measure) score of Sampling Adequacy, Bartlett's test of sphericity and Communalities extraction were 0.57, sig. of 0.00 and ≥ 0.4 respectively thereby supporting; factor analysis. On PCA 6 had an eigenvalue > 1. All of these 6 principal components were found maintainable on The Monte Carlo PCA for Parallel Analysis and they together explained 66.20% of the cumulative variance. Their respective taxonomies were emancipation (PC 1), family heritage (PC 2), stimuli (PC 3), faith (PC 4), education (PC 5), and self-hegemony (PC 6). On regression analysis, the four important influencers of spirituality were; participant’s origin from a joint family (p – 0.00), their daily routine for spiritual enhancement (p-0.01), respect for other religions (p-0.00), and self-motivation (p-0.01). Conclusion: Emancipation (freedom from family bondage), the presence of religious family background, a fixed daily routine, belief in all religions, an unremitting drive for spiritual education, and self-hegemony were dominant components that determined spirituality in Indian Saints. Translating these drivers for the benefit of commoners may enrich their overall health and wellness.

Principal component analysis (PCA) is a technique used to emphasize variation and bring out strong patterns in a dataset. It is often used to make data easy to explore and visualize. The primary objective of the present study was to record information of zooplankton diversity in a systematic way and to study the variability and relationships among seasons prevailed in Gulf of Mannar. The PCA for the zooplankton seasonal diversity was investigated using the four seasonal datasets to understand the statistical significance among the four seasons. Two different principal components (PC) were segregated in all the seasons homogeneously. PCA analyses revealed that Temora turbinata is an opportunistic species and zooplankton diversity was significantly different from season to season and principally, the zooplankton abundance and its dynamics in Gulf of Mannar is structured by seasonal current patterns. The factor loadings of zooplankton for different seasons in Tiruchendur coastal water (GOM) is different compared with the Southwest coast of India; particularly, routine and opportunistic species were found within the positive and negative factors. The copepods Acrocalanus gracilis and Acartia erythrea were dominant in summer and Southwest monsoon due to the rainfall and freshwater discharge during the summer season; however, these species were replaced by Temora turbinata during Northeast monsoon season.

Somaclonal Variations

Micropropagation techniques allow the mass production of banana plants but can cause somaclonal variations such as dwarfism. Changes in the metabolite profile during micropropagation of normal (NP) and dwarf (DP) banana plants have not been described. Both, NPs and DPs of banana Musa AAA cv. Williams were micropropagated and the metabolite profile of vitroplants was assessed at the proliferation (PP), rooting (RP) and the second greenhouse-acclimatization (APII) phases of tissue culture. Metabolites from 10 DPs and 10 NPs meristems from each micropropagation phase were extracted and identified by gas chromatography coupled with mass spectrometry (GC-MS). Principal component analysis (PCA) and test of statistical significance were applied to detect differentially accumulated metabolites. The PCA showed a clear grouping of DPs separated from NPs in RP and APII. Among the differentially accumulated metabolites, various precursors of apoplast components including arabinose and galactose or deoxygalactose in both PP and RP, as well as mannose and fucose in APII were under-accumulated in DPs. Results suggest affected apoplast composition during micropropagation of DPs.

Abstract Background The National Health Service in England “Long Term Plan” aims to prevent 150,000 strokes and myocardial infarctions over the next 10 years. To achieve this, resources are being allocated to improve early detection of conditions strongly associated with cardiovascular disease. This includes working towards people routinely knowing their “ABC” risk factors (“A”: atrial fibrillation (AF), “B': hypertension and “C”: high cholesterol) (1). Purpose The aims of this study were to: 1) determine the proportion of participants with “A”, “B”, and “C” criteria; and 2) to identify risk factors for patients fulfilling any of these criteria. Methods LIPIDOGRAM2015 was a nationwide cross-sectional survey for adults in Poland. Adults were recruited in 2015 and 2016 by 438 family physicians. For the ABC criteria, “A” was defined as AF identified in the medical records of the participant, “B” was defined as either systolic blood pressure greater than 140mmHg or diastolic blood pressure greater than 90mmHg or both, and “C” was defined as total cholesterol greater than 200mg/dL (5.17mmol/L). The scaled and centred dataset underwent principal component analysis using singular value decomposition to achieve dimensionality reduction. K-means clustering was used to stratify patients with Hartigan's rule being used to identify optimal K number (2–4). The p-value for statistical significance used in this study was p&lt;0.01 unless otherwise specified. Results 13,724 patients were included in the study. 71.0% (n=9,747) of participants fulfilled the criteria for one or more of the “A”, “B” or “C” components (Fig. 1). 26 variables were used in this analysis with Principal Component Analysis showing 7 principal components explaining over 50% of the variance with 20 components explaining over 90%. K-means clustering was also performed, finding 39 separate clusters. Correlations and statistical significance tests showed a high degree of variability between variables. Participants with AF were older (mean (SD) 67.7 (9.5) vs 55.7 (13.7), p&lt;0.0001), with higher prevalence of concomitant coronary heart disease (CHD) (OR 6.73, 95% CL 5.75, 7.87) and ischaemic stroke (OR 13.45, 95% CL 7.66, 23.6). Participants with hypertension were older (mean (SD) 60.1 (SD 12.4) vs 53.8 (14.0), p&lt;0.0001), with a higher BMI (mean (SD) 29.9 (5.1) vs 27.5 (4.8), p&lt;0.0001) and resting heart rate (mean (SD) 75.7 (10.7) vs 72.7 (8.9), p&lt;0.0001), more likely to be male (OR 1.42, 95% CL 1.32, 1.53) and have diabetes (OR 1.61, 95% CL 1.46, 1.78). Participants with high cholesterol showed an inverse correlation with prevalence of both concomitant diabetes (OR 0.85, 95% CL 0.77, 0.94) and CHD (OR 0.85, 95% CL 0.76, 0.94) (Fig. 2). Conclusion Simple demographic and clinical variables could be used to guide targeted screening to increase population awareness of “ABC” status, allowing for a greater proportion of the population to be appropriately managed with cardiovascular prevention strategies.

Skin Biopsies

Introduction. Determining the postmortem interval is usually based on macroscopic-morphological criteria (cadaveric phenomena); some other objective methods are often difficult to access in daily practice; therefore we analyze the usefulness of the histopathological examination of the skin as a supplementary method for determining the postmortem interval. Materials and methods.  23 patients and 92 skin biopsies were analyzed. All samples were taken in a maximum time of 6 h postmortem. Biopsies were classified into 4 groups according to the postmortem interval, with 23 biopsies in each group: 1 (1 to 6 h.); 2 (25 to 30 h.); 3 (49 to 54 h.); 4 (73 to 78 h); 21 histological criteria were analyzed with Fisher test and principal component analysis. Results.  Skin biopsies of 23 corpses (mean age 51.6 years, 15 males and 8 females) were studied. 21 histological criteria were analyzed by Fisher test; statistical significance (p <0.001) with a reliability of 94.61% was achieved in 15 parameters. With the 15 selected parameters, a principal component analysis established that there were differences among the 4 analyzed groups. Conclusions. The skin histological changes may be used as a supplementary parameter in the forensic evaluation of the early postmortem interval.

Background: The Intermittent Claudication Questionnaire (ICQ) is a short questionnaire for the assessment of health-related quality of life (HRQOL) in patients with intermittent claudication (IC). The objective of this study was to translate the ICQ into German and to investigate the psychometric properties of the German ICQ version in patients with IC. Patients and methods: The original English version was translated using a forward-backward method. The resulting German version was reviewed by the author of the original version and an experienced clinician. Finally, it was tested for clarity with 5 German patients with IC. A sample of 81 patients were administered the German ICQ. The sample consisted of 58.0 % male patients with a median age of 71 years and a median IC duration of 36 months. Test of feasibility included completeness of questionnaires, completion time, and ratings of clarity, length and relevance. Reliability was assessed through a retest in 13 patients at 14 days, and analysis of Cronbach’s alpha for internal consistency. Construct validity was investigated using principal component analysis. Concurrent validity was assessed by correlating the ICQ scores with the Short Form 36 Health Survey (SF-36) as well as clinical measures. Results: The ICQ was completely filled in by 73 subjects (90.1 %) with an average completion time of 6.3 minutes. Cronbach’s alpha coefficient reached 0.75. Intra-class correlation for test-retest reliability was r = 0.88. Principal component analysis resulted in a 3 factor solution. The first factor explained 51.5 of the total variation and all items had loadings of at least 0.65 on it. The ICQ was significantly associated with the SF-36 and treadmill-walking distances whereas no association was found for resting ABPI. Conclusions: The German version of the ICQ demonstrated good feasibility, satisfactory reliability and good validity. Responsiveness should be investigated in further validation studies.
