Eating self-regulatory skill, diet quantity, and diet quality of Malaysian healthcare university students: A cross-sectional study

@#Introduction: The ability to self-regulate eating can improve health. This study aimed to determine the relationship between eating self-regulatory skills, diet quantity, and diet quality among Malaysian university students. Methods: This cross-sectional study involved 132 university students. Eating self-regulatory skill was assessed using the Self-Regulation of Eating Behaviour Questionnaire (SREBQ). Dietary intakes from two 24-hour dietary recalls were used to assess diet quantity and quality. Diet quantity was measured as energy and macronutrient intakes, analysed using NutritionistPro. Diet quality was measured using the Malaysian Healthy Eating Index (M-HEI). The relationship between eating self-regulatory skills, diet quantity, and diet quality were evaluated using tests for differences between means and multiple linear regression. Results: Male participants (n=47) consumed more energy than female participants (n=85) (Male: 1850±570 kcal/day, Female: 1596±567 kcal/day, p=0.015). Participants from the Nutrition and Dietetics (N&D) course (n=49) had better M-HEI scores than participants from other health courses (n=83) (N&D course: 52.7±10.5, non-N&D course: 47.2±10.7, p=0.005). The predictors of energy intake were gender (β=-0.193, p=0.023) and SREBQ score (β=- 0.223, p=0.009). Being female and having higher eating self-regulatory skills were associated with lower energy intake. The predictors of diet quality were university course (β=0.240, p=0.005) and SREBQ score (β=0.181, p=0.033). Studying N&D and having higher eating self-regulatory skills were associated with higher M-HEI scores. Conclusion: Higher self-regulation of eating behaviour score is a factor that contributes to lower daily energy intake and higher diet quality score.

Positive Orientation and Psychological Distress: An Examination with Psychiatric Outpatients

@#Introduction: This research was conducted to extend the theoretical construct of positive orientation (PO) to psychiatric outpatients. This research also examined the effect of PO on alleviating stress, anxiety, and depression among psychiatric outpatients. Methods: This cross-sectional survey recruited 301 psychiatric outpatients online. As these respondents have a short attention span, short measures were used to measure PO-related variables (life satisfaction, optimism, self-esteem) and indicators of psychological distress (depression, anxiety, and stress). These outpatients are at the legal age to provide consent for themselves (M = 30.12, SD= 8.11). The majority of them have been identified as male (80.07%). Similarly, the ethnic distribution was unequal, with the majority of these outpatients identified as Malay (85.05%), followed by those who were identified as Chinese (7.31%), Indian (4.32%), and from other ethnic groups (3.32%). Results: Generalized structured component analysis (GSCA) supported that satisfaction with life, optimism, and self-esteem reflect the construct of PO. Furthermore, PO predicted depression, anxiety, and depression negatively. Conclusion: It is possible to replicate the construct of PO with psychiatric outpatients using single item measures for life satisfaction, optimism, and self-esteem. PO is beneficial to psychiatric outpatients as it reduces the severity of depression, anxiety, and stress.

Impact of seasonality on the prevalence and risk factors of Giardia lamblia infections among the aborigines

Objective: To determine the prevalence and risk factors of Giardia (G.) lamblia infections among the aboriginal community during the wet and dry seasons. Methods: A total of 473 stool samples from the aborigines in Temerloh, Pahang, Malaysia were collected during wet (n=256) and dry seasons (n=217). Smear of all the PVA-preserved stool samples were subjected to Trichrome staining and microscopic examination under 1 000 x magnification (Nikon eclipse E100) for the detection of G. lamblia. Positivity was recorded based on the presence of G. lamblia in trophozoite and/or cyst forms. Results: The prevalence of giardiasis was 12.10% and 8.29% during the wet and dry season, respectively. Age of less or equal to 15 years old and presence of other family members with G. lamblia infection were found to be the significant risk factors to acquire G. lamblia infections during both seasons. Untreated water supply was the significant risk factor of giardiasis during the dry season. This study highlighted the possibility of anthroponotic transmission of G. lamblia during both seasons and waterborne transmission during the dry season in the aboriginal community. Conclusions: This study suggests that seasonal variation plays an important role in the prevalence and risk factor of G. lamblia infection in the aboriginal community. Therefore, close contact with Giardia-infected family members and water-related activities or usage of untreated water must be avoided to reduce the burden of G. lamblia infection in this community.

Computed tomography of the head for adult patients with minor head injury: are clinical decision rules a necessary evil?

<p><b>INTRODUCTION</b>This study aimed to evaluate compliance with and performance of the Canadian Computed Tomography Head Rule (CCHR), and its applicability to the Singapore adult population with minor head injury.</p><p><b>METHODS</b>We conducted a retrospective study over six months of consecutive patients who presented to the adult emergency department (ED) with minor head injury. Data on predictor variables indicated in the CCHR was collected and compliance with the CCHR was assessed by comparing the recommendations for head computed tomography (CT) to its actual usage.</p><p><b>RESULTS</b>In total, 349 patients satisfied the inclusion criteria. Common mechanisms of injury were falls (59.3%), motor vehicle crashes (16.9%) and assault (12.0%). 249 (71.3%) patients underwent head CT, yielding 42 (12.0%) clinically significant findings. 1 (0.3%) patient required neurosurgical intervention. According to the CCHR, head CT was recommended for 209 (59.9%) patients. Compliance with the CCHR was 71.3%. Among the noncompliant group, head CT was overperformed for 20.1% and underperformed for 8.6% of patients. Multivariate logistic regression analysis revealed that absence of retrograde amnesia (odds ratio [OR] 4.1, 95% confidence interval [CI] 1.8-9.7) was associated with noncompliance to the CCHR. Factors associated with underperformance were absence of motor vehicle crashes as a mechanism of injury (OR 6.6, 95% CI 1.2-36.3) and absence of headache (OR 10.8, 95% CI 1.3-87.4).</p><p><b>CONCLUSION</b>Compliance with the CCHR for adult patients with minor head injury remains low in the ED. A qualitative review of physicians' practices and patients' preferences may be carried out to evaluate reasons for noncompliance.</p>

A Phenomenological Study on the Turnover Experience of Novice Nurses Working in General Hospital / 한국직업건강간호학회지

PURPOSE: The purpose of this study was to identify novice nurses' experience of turnover. METHODS: Data were collected from June to August, 2014 through in-depth interview and E-mail. Twelve novice nurses with turnover experiences were selected through snowball sampling method. All interviews were recorded with MP3 recorder and transcribed for analyzing by Van Kaam method of phenomenology. RESULTS: The results were divided into 4 categories, 20 themes, and 119 formulated meaning related to turnover experience. These four categories were 'Excessively heavy working environment', 'Relationship problem', 'Physical/emotional withdrawal', and 'Realizing the absence of goal in job'. CONCLUSION: The result of this study will offer anticipatory information to understand of novice nurses' difficulties and to prevent their turnover. And these findings can be used for nursing administrators to design a turnover prevention program more effectively for nurses.

01-3Time-course changes in local and systemic vasomotor activities during a hand warming in young individuals / 日本温泉気候物理医学会雑誌

<b>Objectives:</b> The early local vasodilator response to local warming is predominantly dependent on neural reflexes. However, it is suggested that systemic vasomotor activities are unaffected by a local warming at early stage. The purposes of this study were to assess the hypothesis that systemic vasomotor activities might make an adjustment at early stage of hand warming. <BR><b>Materials and Methods:</b> Thirty-nine young volunteers who were healthy were recruited. Each participant received a right hand bathing at 40°C for 10 minutes. Doppler ultrasound technique was used to monitor the brachial artery mean blood velocity (aMBV) at the heated arm, and changes in aMBV were used to evaluate local vasodilator response to hand warming. Photoplethysmographic technique was used to monitor digital volume pulse (DVP) at the unheated finger, and changes in the DVP derived peak amplitude (DVPampl), reflection index (DVPRI), stiffness index (DVPSI), and heart rate (HR) were used to evaluate vascular distensibility of the unheated upper limb, small artery tone in the lower body, large artery stiffness, and cardiac regulation respectively. The data collected in each minute were averaged as an interval. Comparisons of aMBV, DVPRI, DVPSI, and HR at each interval with their respective baseline values were performed using one-way ANOVA. <BR><b>Results: </b>Plots of one-minute intervals versus aMBV, DVPampl, DVPRI, DVPSI, and HR were shown in Figure. aMBV values presented significant increases with a early peak at the third minute. DVPampl presented significant decrease in the first minute and then reversed to a significant increase at the sixth minute. DVPRI presented a significant increase in the first three minutes, and then returned to the level of baseline. DVPSI and HR did not present any significant changes. <BR><b>Conclusion:</b> At the period of early local vasodilator response to hand warming, systemic vasomotor activities did make a significant adjustment by decreasing vascular distensibility of the unheated upper limb and increasing small artery tone of the lower body, though the activities in heart rate and large artery tone were unaffected. Later, vascular distensibility of the unheated upper limb made a reverse adjustment and reached a significant increase.

A study on paternity testing with 96 autosomal SNPs / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To explore the feasibility of applying autosomal single nucleotide polymorphisms (SNPs) on parentage testing.</p><p><b>METHODS</b>All SNP genotyping results of HapMap (r27) were downloaded from the website. With self-made computer programs, SNPs were extracted when their minor allele frequency (MAF) were ≥ 0.30 among all of the 11 HapMap populations. Ninety-six SNPs were chosen and integrated into the Illumina Goldengate bead arrays on the condition that no linkage disequilibrium was found between them. Three father-child-mother trios (9 samples in total) were tested with the arrays. Cumulative paternity index (CPI) was then calculated and compared with genotyping results using 15 short tandem repeats (STRs)(Identifiler(TM)).</p><p><b>RESULTS</b>Family 1 was found to have nine SNPs or seven STRs that did not conform to the Mendelian laws, Family 2 had 13 such SNPs or seven STRs, and Family 3 only had one such SNP but no STR. For Family 3, when all of the 96 SNPs were used in combine, the CPI was 1207, which had contrasted with the CPI by the 15 STRs, i.e., 355 869.</p><p><b>CONCLUSION</b>When applied to paternity testing, the paternity exclusion (PE) value for a SNP is usually less than 1/3 of that of a STR. The proportion of SNPs not comforming to the Mendelian laws for the tested SNPs may not be as high as that of inconsistent STRs over all tested STRs. Because of the low mutation rate of a SNP, the CPI will be greatly reduced even if one SNP did not conform to the Mendelian laws. Therefore, highly accurate testing methods are required to reduce artificial errors when applying SNPs for paternity testing.</p>

Anthropological Study on Ancient Human Skull and Teeth Discovered from Urn Coffin of Proto-Three Kingdoms Period in Korea / 체질인류학회지

Increase in agricultural production or steel manufacturing during Proto-Three Kingdoms Period enabled ancient people to establish well-organized ancient kingdoms in Korean peninsula. A pottery in which human skeletons were buried, the urn coffin, has been regarded as one of the frequently used burial system in ancient Korean society. Among them, the small-sized urn coffin was thought to be used for reburial of adult skeleton or burial for infants and children. In this report, we showed that the human adult bones were buried in a very unique pattern. Based on anthropological study, the dead person buried in the urn coffin died in his/her 30s; and every bone fragment belonged to human skull without exception. The dead person might be a warrior killed in action because there have been reports on exclusive burial of skull in a small-sized, ancient urn coffin in Japan, that was commonly interpreted as the burial of ancient warrior's heads decapitated during ancient battle, and were reburied in the burial ground. Nevertheless, considering that the cervical bones were not found along with the skull bone fragments, the tell tale sign of decapitation, more future studies are needed to confirm the hypothesis. However, even so, it could not be easily denied that very unique funeral customs: burial of human adult skull in a small-sized urn coffin, prevailed in the ancient Korean societies in certain regions.

Construction of Medieval Skeleton Collections with Human Remains from Tombs of Goryeo Dynasty, Korea / 체질인류학회지

Skeletal remains collected from the archaeological fields must be maintained carefully, for being used in scientific studies on the physical characteristics, health status, and pathological disease of the ancient or medieval human populations. Even if Joseon Dynasty Human Sample Collection might be a good example for such studies, few of bone collections predated the Joseon Age (e.g. Goryeo Dynasty) have been established until now, possibly owing to poor preservation condition of archaeological sites in Korea. In this study, we performed anthropological studies on a few cases of Goryeo skeletons, which have been rarely reported by anthropologists in Korea. Judging from the preservation status of bones found in various types of Goryeo graves (e.g. earthen- or stone-chambered tombs), many cases seem to be cremated in accordance with Buddhist funeral rites. Goryeo bone collections must be constructed with the bones identified in the earthen tombs, which were preserved much perfectly than those of any other types of Goryeo tombs.
