Healthy Behaviors and Illness Perception of Patients with Myocardial Infarction the First 3 Months

Purpose: This study was conducted to determine the healthy lifestyle behaviors and illness perception of patients within the first three months after suffering from a myocardial infarction. Method: This descriptive and cross-sectional study was conducted with 112 patients who had myocardial infarction and underwent coronary angiography between November 2016 and August 2018. The data of the study were obtained by using “Patient Information Form”, “Health Promoting Lifestyle Profile-II”, and “Illness Perception Questionnaire”. Descriptive statistics, independent sample t test, one-way analysis of variance and the analysis of variance for repeated measures were used in SPSS 16 program in order to analyze the data. Results: It was observed that total and subscale mean scores of the patients for the Health Promoting Lifestyle Profile-II increased over time, and the patients developed healthy behaviors (p<0.01). When it came to the attributions consenting the disease, the highest mean score was observed in the personal control subscale; whereas, the lowest mean score was observed from the timeline (cyclical) subscale (p<0.01). In terms of causes of disease, the highest mean score was obtained from the risk factors subscale; whereas, the lowest mean score was obtained from accident and bad luck subscale (p<0.01). The mean score of the patients for the illness identity subscale in three evaluations increased over time. Likewise, the patients were found to strongly believe that the number of symptoms associated with the disease was high (p<0.05). Conclusion: The healthy lifestyle behaviors of the patients were found to be more positive in receiving regular follow-up. Moreover, it appeared that they were able to better understand the symptoms of their disease over time. They positively believed in being able to manage their disease and treatments.
Detection of Fecal SARS-CoV-2 RNA in a Prospective Cohort of Children with Multisystem Inflammatory Syndrome (MIS-C)

Multisystem inflammatory syndrome related to SARS-CoV-2 infection (MIS-C) is a rare severe illness affecting pediatric patients. No data are available in literature about the presence of SARS-CoV-2 RNA in faeces in patients with MIS-C. The SARS-CoV-2 positivity was evaluated in fecal samples obtained in a prospective cohort of pediatric patients admitted to our tertiary Hos-pital and diagnosed with MIS-C or COVID-19 between April 15, 2020, and February 29, 2021. The real-time RT-PCR was performed using a validated kit. The assay measures 3 target genes: SARS-CoV-2 gene E, gene N, gene ORF1ab. Overall, 16/63 (25%) fecal samples revealed the pres-ence of SARS -CoV-2 RNA. No differences were detected about time from presumptive viral ex-posure and the time of stool collection (14 vs 8 days, p> 0,05) as well as about the presence of gas-trointestinal symptoms (p>0.05) between patients with positive (+) stools for SARS-CoV-2 RNA and patients tested negative (-). Among children with MIS-C, stools were collected 27.5 days as median (95% CI 14-34) after presumed contact and the positivity rate was 12.5% (4/32). According to our data, we could suggest contact precautions with all patients with MIS-C. Further sample collection is ongoing to verify our preliminary data.
COMPARATIVE HISTOLOGICAL STUDY ON THE GLANDS OF SKIN IN BUFFALO AND COW

This study was done to compare between the skin of buffaloes and cows. Six samples from different regions of the body were collected from local abattoirs in Baghdad. The skin specimens were fixed in formalin solution. Routine histological techniques were carried out on these samples. For staining, hematoxylin and eosin stains were used then samples were examined under light microscope. Even the excretory ducts of sweat glands in both cows and buffaloes were stratified cuboidal epithelium, the sweat glands in buffaloes were poorly developed, less numerous, smaller in size and lies deeply in the dermis with longer duct comparing to that of the cows. Their secretory acini were surrounded by fewer number of myoepithelial cells. The apocrine sweat glands were distributed all over the body regions while the merocrine sweat glands were distributed in limited body regions. On the other hand, the sebaceous glands of buffaloes were well developed and appeared as larger in size and more lobulated comparing to the cows. The above thoughts explain why the buffaloes considered as poor thermoregulator animals. In regard to the mechanism of thermoregulation, the present study concluded that there was a reverse relationship between the function of sebaceous and sweat glands.
Oral Lactobacillus Species in Systemic Sclerosis

In systemic sclerosis (SSc), the gastrointestinal tract (GIT) plays a central role in the patient’s quality of life. The microbiome populates the GIT, where a relationship between the Lactobacillus and gastrointestinal motility has been suggested. In this study, the analysis of oral Lactobacillus species in SSc patients and healthy subjects using culture-independent molecular techniques, together with a review of the literature on microbiota and lactobacilli in SSc, has been carried out. Twenty-nine SSc female patients (mean age 62) and twenty-three female healthy subjects (HS, mean age 57.6) were enrolled and underwent tongue and gum swab sampling. Quantitative PCR was conducted in triplicate using Lactobacillus specific primers rpoB1, rpoB1o and rpoB2 for the RNA-polymerase β subunit gene. Our data show significantly (p = 0.0211) lower LactobacillusspprpoB sequences on the tongue of patients with SSc compared to HS. The mean value of the amount of Lactobacillus ssprpoB gene on the gumsofSSc patients was minor compared to HS. A significant difference between tongue and gums (p = 0.0421) was found in HS but not in SSc patients. In conclusion, our results show a lower presence of Lactobacillus in the oral cavity of SSc patients. This strengthens the hypothesis that Lactobacillus may have both a protective and therapeutic role in SSc patients.
Confounding Factors Influencing the Kinetics and Magnitude of Serological Response Following Administration of BNT162b2

Background: Little is known about potential confounding factors influencing the humoral response in individuals having received the BNT162b2 vaccine. Methods: Blood samples from 231 subjects were collected before and 14, 28, and 42 days following coronavirus disease 2019 (COVID-19) vaccination with BNT162b2. Anti-spike receptor-binding-domain protein (anti-Spike/RBD) immunoglobulin G (IgG) antibodies were measured at each time-point. Impact of age, sex, childbearing age status, hormonal therapy, blood group, body mass index and past-history of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection were assessed by multivariable analyses. Results and Conclusions: In naïve subjects, the level of anti-Spike/RBD antibodies gradually increased following administration of the first dose to reach the maximal response at day 28 and then plateauing at day 42. In vaccinated subjects with previous SARS-CoV-2 infection, the plateau was reached sooner (i.e., at day 14). In the naïve population, age had a significant negative impact on anti-Spike/RBD titers at days 14 and 28 while lower levels were observed for males at day 42, when corrected for other confounding factors. Body mass index (BMI) as well as B and AB blood groups had a significant impact in various subgroups on the early response at day 14 but no longer after. No significant confounding factors were highlighted in the previously infected group.

Profile and Outcome of Hospitalized Patients with Severe COVID-19 in a Tertiary Hospital in Southern Nigeria

Results: A total of 90 hospitalised patients, comprising of 62 (68.9%) males with a median age of 44 years were recruited. A comorbid disease condition was present in 46 (51.1%), with hypertension in 35 (38.9%) and diabetes 17 (18.9%) as the leading comorbidities. Fever 56 (62.2%), dyspnoea 46 (51.1%) and dry Cough 31 (34.4%) were the leading symptoms. Thirty-seven (41.1%) patients had a severe disease while 7 patients died. Predictors of severity were male gender (O.R = 3.44, CI = 1.226 9.64, p = 0.02), presence of a comorbidity, (OR = 3.12, CI = 1.98 4.86, p = < 0.001), hypertension (OR = 2.88, CI = 1.65 5.01, p = < 0.001) and heart disease (LR = 7.61, CI = 0.79 0.99, p = 0.02). The predictors of mortality were hypertension and presence of comorbidity with, (p = < 0.001, O.R = 3.18 and CI = 3.587 7.814) and (p = < 0.001, O.R = 1.176 and CI = 2.389 5.786), respectively. Case fatality in all patients and patients with severe disease was 7.8% and 18.9% respectively.
Systematic review and meta-analysis of vitamin D deficiency in different pregnancy on preterm birth

Supplemental Digital Content is available in the text Abstract Background: Current studies suggest that vitamin D deficiency during pregnancy can produce a certain effect for preterm birth (PTB), but there is no research showing whether vitamin D deficiency has a consistent effect in different pregnancies; thus, we conducted a systematic review and meta-analysis of 24 observational studies, grouping them according to the gestational age at the time of serum sampling, to investigate whether vitamin D deficiency in different periods of gestation has different effects on PTB and to provide an evidence-based basis for pregnant women to measure and supplement vitamin D. Methods: The databases PubMed-Medline, EMBASE, the Cochrane Library, Web of Science, EBSCO, CBM, and CNKI were searched until February 2020. Two researchers independently assessed the eligibility and quality of studies, and STATA 12.0 software was used for meta-analysis. Result: Seven cohort studies, 13 case–control studies, and 4 cross-sectional studies were included from 2500 articles by inclusion and exclusion criteria. After adjusting for age, race, and other confounding factors, meta-analysis results showed that vitamin D deficiency in the first trimester, the second trimester, and the third trimester did not increase the risk of PTB (odds ratio (OR) = 1.01, 95% confidence interval (CI) (0.88, 1.16), P = . 867; OR = 1.12, 95%CI (0.92, 1.37), P = . 249; OR = 1.05, 95%CI (0.87, 1.27), P = . 602). However, there was moderate heterogeneity in the study of vitamin D deficiency in the second trimester, and subgroup analysis suggested that vitamin D deficiency in the second trimester may increase the risk of PTB (OR = 1.33, 95%CI (1.15, 1.54), P = . 000). A sensitivity analysis of the second trimester showed that excluding any 1 study did not significantly change the results. Conclusions: Vitamin D deficiency in early and late pregnancy may not be associated with PTB, while vitamin D deficiency in middle pregnancy is likely to have an important effect on PTB. Vitamin D levels should be measured in the second trimester of pregnancy, and vitamin D supplements should be provided if necessary.
Dose-dependent Vitamin C Supplementation Enhances Orthodontic Tooth Movement in Wistar Rats

The aim of study is to evaluate the effect of different doses of vitamin C supplement on amount of orthodontic tooth movement. Thirty 6-week-old male Wistar rats were divided into 3 groups according to amounts of feeding vitamin C per day: 0 (control), 500 (C500) and 1,000 (C1,000) mg/day. A 60-g mesial force was applied to maxillary right first molar by using 9-mm nickel-titanium closed-coil spring. Interproximal distance between maxillary right first and second molars was measured after 7 and 14 days. All rats were terminated at day 14, Tartrate-resistant acid phosphatase (TRAP) positive areas and remaining inter-radicular bone areas were measured. Data were analyzed by using Analysis of variance with post hoc test and Welch’s test (P<0.05). The mean distances of tooth movement were increased in a dose dependent manner with significant difference between the control and C1,000 groups at day 14. The TRAP-positive areas were increased but the inter-radicular bone areas were decreased in both vitamin C supplement groups, there were no significant difference. This study suggests that dietary vitamin C supplement at 1,000 mg/day could enhance amounts of tooth movement during orthodontic application. However, the osteoclast profile and inter-radicular bone areas were not clearly different. Experimental article (J Int Dent Med Res 2021; 14(1): 145-150)
Prevalence and risk factors of Hepatitis B virus infection among blood donors in Gabonese National Blood Transfusion Center: A cross-sectional and analytic study

Hepatitis B virus (HBV) infection is prevalent in Gabon and poses a potential risk of transmission by blood transfusion. However, few studies have examined epidemiological data regarding HBV infection of Gabonese blood donors. This article reports on research conducted to estimate the seroprevalence of HBV and associated risk factors in the urban population of Gabon. A cross-sectional and analytic study survey of blood donors attending at the Gabonese National Blood Transfusion Center, was carried out between June and August 2020. The ELISA technique (Evolis®, BioRad) and the chemiluminescence technique (Cobas® e601, Roche) had been used for the detection of hepatitis B surface antigens in the plasma of donors. Repeatedly reactive hepatitis B surface antigen levels among first-time and repeat donors were used to assess prevalence and risk factors using multivariable logistic regression. Results revealed that a total of 3665 donations were collected at the Gabonese National Blood Transfusion Center, of which 100 were con? rmed HBV positive. The seroprevalence of HBsAg among total blood donors was 5.5% (95% confidence interval [CI] = 4.4 - 6.7) indicating a moderate burden. In our multivariate analysis controlling for age, HBsAg positivity was associated with first-time donor status (aOR = 6.5) and residence outside of Libreville (aOR = 1). The prevalence of HBsAg among Gabonese blood donors is at a moderate-level endemicity among first-time donors, indicating the need to further limit the burden. In this Gabonese context, status of first-time blood donor and living in rural settings are primary risk factors of HBV-infection, and henceforth considered as exclusionary criteria for blood donation in Gabon. Key words: Hepatitis B, prevalence, risk factors, blood donor
Chemical composition and antifungal activity of essential oil of fresh leaves of Cinnamomum zeylanicum from Benin against six mycotoxigenic fungi isolated from a traditional cheese wagashi

Introduction Traditional cheese locally called wagashi obtained without ripening in Benin is an important source of animal proteins especially for rural populations. It is widely consumed not only by rural poor people but also in the main cities of Benin. Due to its proteins content, wagashi could efficacy contribute to the resolution of nutritional problems due to the deficiency of proteins (Kèkè et al., 2008). However, wagashi is produced and preserved using rudimentary methods under unsanitary conditions which may lead to the contamination of the product by toxinogenic or pathogenic microorganisms especially fungi. The contamination of this product by fungi may contribute to the loss of its quality and safety. In fact, the fungal growth may result in several kinds of cheese spoilage: off-flavours, toxins, discolouration, mycolytic enzymes and rotting (Filtenborg et al., 1996). Furthermore, fungi produce allergenic compounds and toxic metabolites (mycotoxins) which may penetrate the cheese and affect the consumer’s health (Nasser, 2001). It was reported that occurrence of Aflatoxin M1 in cheese could probably increase the risk of developing cancer (Elkak et al., 2012) or toxic and carcinogenic effects (WHO-IARC, 2002). Moreover, fungi have been reported by Aissi et al. (2009) to cause extensive deterioration of wagashi which affects its preservation and may lead of occurring of mycotoxins carcinoms, mutagenicity and liver cancer. A better control measures to prevent spoilage of wagashi is necessary to avoid its contamination by mycoflora and minimize public health hazards. The use of synthetic fungicides to control cheese spoilage moulds has been discouraged due to their effects on cheese, carcinogenicity, teratogenicity, high and acute residual toxicity, long-term degradation, and other side-effects in humans (Barkat and Bouguerra, 2012). One of the major problems related to the use of these chemicals is that the fungi develop resistance. The use of higher concentrations of chemicals, to overcome the microbial resistance further enhances the risk of high level toxic residues in the products (Angelini et al., 2006). Alternative natural additives are therefore needed in order, to guarantee food safety in preserved wagashi. Aromatic plants are traditionally employed for seasoning and prolongation of shelf life of food (Wang and Huang, 2010). The majority of their properties are due to the essential oils produced by their secondary metabolism (Rashid et al., 2010). Great interest is given to these oils by the industry and scientific research for two reasons: on the one hand, their antimicrobial activity (Burt, 2004), on the other hand, essential oils are recognized as substances GRAS, which make them useful as natural preservatives in food industries (Nguefack et al., 2004; Gachkar et al., 2007). Among the aromatic plants, a spice Cinnamomum zeylanicum native of Sri Lanka and South India and commonly
THE HOFFMANN–JØRGENSEN INEQUALITY IN METRIC SEMIGROUPS1

We prove a refinement of the inequality by Hoffmann–Jørgensen that is significant for three reasons. First, our result improves on the state-of-the-art even for real-valued random variables. Second, the result unifies several versions in the Banach space literature, including those by Johnson and Schechtman [Ann. Probab. 17 (1989) 789–808], Klass and Nowicki [Ann. Probab. 28 (2000) 851–862], and Hitczenko and Montgomery-Smith [Ann. Probab. 29 (2001) 447–466]. Finally, we show that the Hoffmann–Jørgensen inequality (including our generalized version) holds not only in Banach spaces but more generally, in a very primitive mathematical framework required to state the inequality: a metric semigroup G . This includes normed linear spaces as well as all compact, discrete or (connected) abelian Lie groups.
Ovarian dynamics, hormone profiles, and characterization of ovarian and uterine blood flow in cycling Sahiwal cows

The objectives were to investigate the ovarian dynamics and hormonal profiles during the oestrus cycle, and to characterize the ovarian and uterine blood flow (OBF versus UBF) indices on the extent of vascular perfusion towards the dominant follicle (DF) or corpus luteum (CL) during the peri-ovulatory follicular wave in Sahiwal cows. In experiment 1, cyclic cows (n = 21) were selected at their spontaneous oestrus (day 0) and subjected to B-mode ultrasonography throughout the oestrus cycle. In experiment 2, cyclic cows (n = 9) were randomly selected at day 0, and categorized according to the intra-ovarian patterns as ovaries with DF (n = 3), CL (n = 3) or both (DF+CL; n = 3) to characterize the OBF and UBF indices using Doppler ultrasonography. The length of the oestrus cycle (days), number of follicular waves (n) and size (mm) of DF and CL were 20.1 ± 0.9, 2.1 ± 0.2, 14.7 ± 0.7 and 15.9 ± 2.5, respectively. The concentrations (ng/mL) of plasma progesterone increased linearly, and a peak was attained at day 12.2 ± 1.0. However, it reduced linearly with the onset of luteolysis at day 16.4 ± 0.3 of the oestrus cycle. The plasma progesterone (P4) concentrations and the diameter of CL correlated throughout the oestrus cycle. The mean OBF and UBF indices did not differ between intraovarian patterns. Taken together, this information on reproductive physiological parameters could be used to develop synchronization protocols to improve reproductive management in Sahiwal cows.

SIMULATION OF DISPLACEMENT DAMAGE CROSS SECTION OF CUPROUS OXIDE/ZINC OXIDE (Cu2O/ZnO) BASED HETEROJUNCTION DEVICE

In space, semiconductor devices are vulnerable to the various effect of a high energy level of radiation, causing Single Event Upsets (SEU), damaging or altering the lattice structure of the semiconductor device. The effect of energy level exposure and angle of trajectory on semiconductor device had received very little attention. In this research, the simulated sample is cuprous oxide/zinc oxide (Cu2O/ZnO) based Heterojunction Device. The device was initially characterized using the General-Purpose Photovoltaic Device Model (GPVDM) simulation to obtain the current-voltage (IV) and current density-voltage (JV). The radiation damage was then modelled using cascade simulation on the effect of elastic and inelastic scattering by Cobalt-60 (Co) ions using Stopping and Range of Ions in Matter (SRIM-TRIM) simulation. GPVDM simulation shows, the recombination rate of hole and electrons at Voc is obtained to be 3.985e ms. SRIM-TRIM simulation shows that at 1.5 MeV particle radiation energy, it was found that the stopping range is about 1.07 μm and at a maximum energy of 10 MeV, the stopping range is about 4.08 μm. At ECo = 1500 keV, ECo = 5000 keV and ECo = 10000 keV, the total ionization is 1173.8 keV/ Ion 4267 keV/Ion and 9550.8 keV/Ion at an ion angle trajectory of 60. This paper highlights the roles of energy of the Primary Knock-on Atom (PKA) and the response of device to ion collision cascade at different irradiation angle.
