Association of MTR A2756G Gene Polymorphism with Risk of Head and Neck Cancer

Objective: To perform genotyping for MTR A2756G polymorphism and identification of risk factors associated with head and neck squamous cell carcinoma (HNSCC). Study Design: Cross section, comparative study. Place and Duration of Study: The study was carried out at the Department of Biochemistry of Quaid-i- Azam University, Islamabad from October 2014 to August 2015. Materials and Methods: In this study, 292 diagnosed patients HNSCC and 324 normal individuals without any history of cancer were enrolled. Blood samples of patients and controls were collected in ethylenediamine tetra acetic acid (EDTA) and DNA was extracted using conventional method. All samples were genotyped for the MTR A2756G polymorphism using PCR-RFLP. Frequency of polymorphism was compared between HNSCC patients andcontrols. MultipleLogisticRegression(MLR)andchi-squaretestwasperformedtoexaminetheassociation of MTR A2756G polymorphism with risk factor. Results: Chi-square test of independence showed statistically significant difference among the variables of age, smoking and MTR A2756G genotype (p-value<0.05). Multivariate analysis showed that smoking (adjusted OR, 3.7; 95% CI, 2.3 – 6.0), age groups 41 – 50 years (adjusted OR, 3.6; 95% CI, .9 – 6.7) and > 60 years (adjusted OR, 3.5; 95% CI, 1.7 – 7.3), MTR 2756 AG genotype (adjusted OR, 2.1; 95% CI, 1.3 – 3.5) is associated with increased risk of HNSCC. Conclusion: The results suggest that the genetic polymorphism MTR A2756G is associated with the occurrence of HNSCC in the Pakistani population while the individuals between 40 to 50 years of age and those who are smokers are at a greater risk of developing HNSCC.

Background: The SSRIs being used as 1st line therapy in treatment of depression have delayed therapeutic effect which makes the patient vulnerable to an increased risk of suicide and decreased adherence to the treatment and will prematurely discontinue the therapy. The present study was conducted to evaluate if low dose mirtazapine-escitalopram combination therapy has any add on benefit over monotherapy with escitalopram.Methods: In a single-centered, comparative study involving patients with depression attending the out-patient after screening and exclusion, 60 eligible patients were randomly assigned to receive tablet mirtazapine 7.5 mg plus tablet escitalopram 10 mg intervention or tablet escitalopram 10 mg plus placebo intervention in a double-blind 6-week treatment phase. The primary outcome measure was the change in the 17-item Hamilton Depression Rating Scale (HDRS) and Montgomery-Asberg Depression Rating Scale (MADRS) score from baseline. Participants were evaluated at baseline, 1st, 2nd,4th and 6th week. Results were analyzed using Chi-Square test for adverse effects and independent t-test analysis for efficacy parameter.Results: In the analysis of results at 6th week the numbers of patients achieved remission in mirtazapine group are more with a p-value of 0.018 which is significant and the numbers of responders in mirtazapine group are also more which is statistically significant on chi-square test. There is no significant difference was observed between the two groups with reference to occurrence of adverse effect.Conclusions: Adding low dose mirtazapine has an added benefit in terms of efficacy and getting remission early with more number of responders in the treatment of major depression.

Background: The 5-methyltetrahydrofolate-homocysteine methyltransferase gene (MTR) encodes the methionine synthase enzyme (OMIM 156570). Methionine synthase synthesizes methionine by re-methylation of homocysteine. A single nucleotide variation MTR-A2756G may affects the function of methionine synthase enzyme, which could lead to the development of head and neck squamous cell carcinoma (HNSCC).Methods: In current study, 292 HNSCC patients and 324 normal individuals without any history of cancer (control) were enrolled. EDTA whole blood samples of patients and control individuals were collected, and DNA was extracted. All samples were genotyped for MTR-A2756G polymorphism using polymerase chain reaction-restriction fragment length polymorphism. Frequency of polymorphism was compared between HNSCC patients and control individuals. The association of MTR-A2756G polymorphism with risk factors was statistically analysed through multivariate analysis (multiple logistic regression) whereas univariate analysis (chi square) was performed for group comparisons. Results: Univariate analysis revealed that the frequency of groups like age, smoking and MTR-A2756G genotype was different in HNC patients and controls (p value <0.05). Multivariate analysis showed that smoking (adjusted OR, 3.7; 95% CI, 2.3-6.0), age groups 41-50 years (adjusted OR, 3.6; 95% CI, .9-6.7) and >60 years (adjusted OR, 3.5; 95% CI, 1.7-7.3), MTR-A2756G genotype (adjusted OR, 2.1; 95% CI, 1.3-3.5) is associated with increased risk of HNSCC.Conclusions: Our data suggests that the MTR-A2756G polymorphism is associated with the occurrence of HNSCC in Pakistani population while the individuals between 40 to 50 years of age and tobacco smokers are at a greater risk of developing HNSCC.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

BACKGROUND Seroprevalence of IgG antibodies against SARS-CoV-2 is an important tool to estimate the true extent of infection in a population. However, seroprevalence studies have been scarce in South East Asia including India, which, as of now, carries the third largest burden of confirmed cases in the world. The present study aimed to estimate the seroprevalence of anti-SARS-CoV-2 IgG antibody among hospitalized patients at one of the largest government hospital in India OBJECTIVE The primary objective of this study is to estimate the seroprevalence of SARS-CoV-2 antibody among patients admitted to the Medicine ward and ICU METHODS This cross-sectional study, conducted at a tertiary care hospital in North India, recruited consecutive patients who were negative for SARS-CoV-2 by RT-PCR or CB-NAAT. Anti-SARS-CoV-2 IgG antibody levels targeting recombinant spike receptor-binding domain (RBD) protein of SARS CoV-2 were estimated in serum sample by the ELISA method RESULTS A total of 212 hospitalized patients were recruited in the study with mean age (±SD) of 41.2 (±15.4) years and 55% male population. Positive serology against SARS CoV-2 was detected in 19.8%patients(95% CI 14.7-25.8). Residency in Delhi conferred a higher frequency of seropositivity 26.5% (95% CI 19.3-34.7) as compared to that of other states 8% (95% CI 3.0-16.4) with p-value 0.001. No particular age groups or socio-economic strata showed a higher proportion of seropositivity CONCLUSIONS Around, one-fifth of hospitalized patients, who were not diagnosed with COVID-19 before, demonstrated seropositivity against SARS-CoV-2. While there was no significant difference in the different age groups and socio-economic classes; residence in Delhi was associated with increased risk (relative risk of 3.62, 95% CI 1.59-8.21)

Hypertension is one of the number one causes of death and disability in the world. Hypertension contributes nearly 9.4 million deaths from cardiovascular disease each year. Hypertension can cause undesirable effects, it needs good handling, one of them is by doing a hypertension diet. To carry out a hypertension diet requires knowledge, lack of knowledge can increase risk factors for hypertension. This study aims to determine the relationship of the level of knowledge about hypertension diet to the incidence of hypertension in the elderly at the Baloi Permai Public Health Center Batam City. This research method is an analytic observational with a cross-sectional approach conducted at the Baloi Permai Public Health Center Batam City 2018. Sampling technique is a total sampling with a sample of 64 people in 2018 determined by inclusion and exclusion criteria. The results of the study were analyzed with frequency distribution and then tested with the Chi-square test. Based on the results of this study indicate that of the 64 respondents found elderly who have a good level of knowledge are 41 people (64.1%), 48 people (75.0%) have an age range between 60-70 years. 27 people (42.2%) elderly have the last high school education and 40 people (62.5%) have jobs as entrepreneurs. Elderly people who have normal blood pressure are 40 people (62.5%), and those affected by hypertension are 24 people (37.5%). The elderly who have a family history of hypertension is 21 people (32.8%) and those who do not have a history of hypertension are 43 people (67.2%). Chi-Square Test analysis results show the significance value p = 0.009. This number is significant because the p-value is smaller than the significance level (Î±) â‰¤ 5% (0.05), so H0 is rejected and Ha is accepted. Therefore it can be concluded that there is a significant relationship about the level of knowledge about the hypertension diet to the incidence of hypertension in the elderly. From the results of this study it was concluded that there was a relationship between the level of knowledge about the hypertension diet and the incidence of hypertension in the elderly at the Baloi Permai Public Health Center Batam City in 2016.

Objective: To evaluate patient perception of the smile focused on analysis of the upper incisors. Design: Cross-sectional study. Setting: Department of Clinical and Social Dentistry at Federal University of Paraíba, João Pessoa, Brazil. Participants: The sample consisted of 135 individuals (73 women and 62 men). Methods: Images with different characteristics associated with the incisal edges were shown at random and analysed using a Likert scale. Data were analysed using the Chi-square test or Fisher’s exact test with a statistically significant difference ( P < 0.05). Results: Smile I (difference of 1.5 mm in relation to the central incisor and lateral) was considered the most aesthetic, while Smile III (no difference in height between the central and lateral incisors) was the least aesthetic. A significant difference was found between perception of smile II (difference of 1 mm in relation to the central incisor and lateral) and age groups ( P < 0.005), with 31% (n = 13) of individuals aged 45–64 years considering smile II as not pleasant, 4.4% (n = 2) aged 15–24 years and 8.3% (n=4) aged 25–44 years and 4.4% (n = 2) aged 15–24 years considering the same. A significant difference was also found in relation to educational background of the assessor and smile perception, with smile III ( P = 0.0441) and smile IV ( P = 0.0053) considered the most aesthetic ( P = 0.0116). Conclusion: The smile considered most attractive among the sample was that with 1.5 mm steepness between the central and lateral incisors, while a flat smile arc was considered least attractive.
