ABSTRACT

OBJECTIVE: Cardiovascular diseases (CVD) are one of the most addressed preventable diseases of public health importance. However, the risk estimates and use of these risk scores for CVD prevention are the least explored areas. So, in this study, we explored the different categories of Framingham heart study (FHS) 10-year-CVD risk score and their associated factors among the adult male population in Tamil Nadu, India. METHODS: We used the risk factor level data for male adults aged 18 years and above from the National Family Health Survey (NFHS-5) of Tamil Nadu state, India. Sociodemographic variables, behavioral factors, and physiological/biochemical factors were considered as the risk factor and were estimated using the world health organization (WHO) STEPS categories. FHS 10-year-CVD risk score was calculated using a body-mass index-based published Cox regression equation. RESULTS: Out of 2289 adult males, only 1.12% of the participants had a 10-year CVD risk score greater than 30% and ∼4% of the total participants require statin treatment (FRS-CVD risk score ≥20). Educational status (aOR:14.21, 95 CI: 4.36-46.22- no formal schooling when compared to 10th and above standard), weekly fruit intake (aOR:0.51, 95 CI: 0.27-0.97 when compared to daily fruit intake) and abdominal obesity (aOR:2.43, 95 CI: 1.58-3.74) were found to be associated with higher FRS scores when adjusted for all other factors not involved in FRS calculation. CONCLUSION: Widespread use of this score needs to be encouraged in clinical practices and patients with a higher risk of CVD events should be counselled for lifestyle modifications and compliance with treatment for decreasing the burden due to CVDs.

ABSTRACT

Background: Often, refugees are susceptible to mental health problems due to adversities experienced before, during, and after the flight. Through a cross-sectional study, the present study examines the relationship between different aspects of integration and psychological distress among Afghans living in Norway. Methods: The participants were recruited through e-mail invitations, refugee-related organizations, and social media platforms. The participants (N = 114) answered questions about integration across multiple dimensions (psychological, social, navigational, economic, and linguistic) in line with the Immigration Policy Lab index (IPL -12/24). Hopkins symptoms checklist (HSCL-25) was used to assess psychological distress. Results: Based on hierarchical multiple regression analysis, both the psychological dimension (0.269 p < 0.01) and the navigational dimension (0.358 p < 0.05) of integration predicted psychological distress. Discussion/Conclusion: The results suggest that the psychological aspects of integration, such as being part of a community, having feelings of security, and a sense of belonging, are beneficial for the mental health and well-being of the Afghans in Norway and contribute further to other aspects of integration.

ABSTRACT

The Integration Hypothesis states that acculturating migrants who adopt the integration strategy (i.e. being doubly engaged, in both their heritage culture and in the larger national society) will have better psychological and socio-cultural adaptation than those who adopt any other strategy (Assimilation, Separation or Marginalization). This hypothesis was supported in the original evaluation of the ICSEY project data, using the mean adaptation scores for individuals in the four acculturation clusters. This conclusion was further supported by an analysis that used scores that were derived from the two underlying dimensions. This paper further evaluates this hypothesis meta-analytically using two new methods: Cultural Involvement and Cultural Preference; and Euclidean Distance. The results showed that these two methods provided support for the integration hypothesis, for both psychological adaptation and socio-cultural adaptation. The pattern of relationships was stronger for positive than for negative indicators of adaptation. Theoretical and practical implications of the results are discussed.

ABSTRACT

There is limited information on knowledge, perceptions, and management of sickle cell disease (SCD) in Africa in general and in the Democratic Republic of the Congo (DRC) in particular. This study explored knowledge, perceptions, and burden of 26 parents/caregivers of children with SCD in three selected hospitals in Kinshasa, DRC. We conducted a focus group with in-depth interviews with parents/caregivers of children affected with SCD. Four themes were discussed, including knowledge and perceptions, diagnosis and management, society's perceptions, and the psychosocial burden and the quality of life of the family affected by SCD. The majority of participants/caregivers felt that society, in general, had negative perceptions of, attitudes toward, and knowledge about SCD. They reported that children with sickle cell are often marginalized, ignored, and excluded from society or school. They face a number of challenges related to care, management, financial difficulties, and a lack of psychological support. The results suggest the need to promote measures and strategies to improve knowledge and management of SCD in Kinshasa, DRC.

ABSTRACT

BACKGROUND: Children and young asylum-seekers are often exposed to stressful life events (SLEs) and risk developing psychological symptoms. However, risk and protective factors can positively and negatively influence this vulnerable group's mental health. AIMS: To examine the SLE experiences and psychological symptoms of children and youth who seek refuge in Iceland. And to study the role that gender, travelling (un)accompanied and perceived social support play in the development of psychological symptoms for this population. METHODS: Participants were 75 children and youth of ages 13 to 24 years who sought asylum in Iceland (M = 19.7, SD =3.0, 66.7% male). Sociodemographic and social support data were collected via face-to-face interviews, with the help of interpreters when required, while SLEs, post-traumatic stress, depression, anxiety and behavioural symptoms measures were administered to participants. RESULTS: The results indicated that participants who travelled alone to Iceland had experienced more SLEs than those who travelled accompanied. SLE experiences were associated with post-traumatic stress disorder (PTSD) and other psychological symptoms. Results also revealed that SLE and perceived peer support played a significant role in predicting PTSD symptoms. CONCLUSIONS: Children and young asylum-seekers are exposed to a high number of SLEs, which increases their risk of developing psychological problems. This potential risk underlines the need for early assessments and intervention. Moreover, higher levels of social support were related to less severe PTSD symptoms, suggesting that social resources act as protective factors for these children and youth in helping them cope with SLEs.

ABSTRACT

We assessed the impact of the national lockdown on a rural and tribal population in Tamil Nadu, southern India. A mixed-methods approach with a pilot-tested, semi-structured questionnaire and focus group discussions were used. The impact of the lockdown on health, finances, and livelihood was studied using descriptive statistics. Multivariable logistic regression was carried out to identify factors associated with households that borrowed loans or sold assets during the lockdown, and unemployment during the lockdown. Of the 607 rural and tribal households surveyed, households from comparatively higher socioeconomic quintiles (adjusted odds ratio [aOR], 1.84; 95% CI, 1.01-3.34), with no financial savings (aOR, 2.91; 95% CI, 1.17-7.22), and with larger families (aOR, 1.76; 95% CI, 1.22-2.53), took loans or sold assets during the lockdown. Previously employed individuals from rural households (aOR, 5.07; 95% CI, 3.30-7.78), lower socioeconomic households (aOR, 3.08; 95% CI, 1.74, 5.45), and households with no savings (aOR, 1.78; 95% CI, 1.30-2.44) became predominantly unemployed during the lockdown. Existing government schemes for the elderly, differently abled, and widows were shown to be accessible to 89% of the individuals requiring these schemes in our survey. During the focus group discussions, the limited reach of online classes for schoolchildren was noted and attributed to the lack of smartphones and poor Internet connectivity. Although the sudden, unannounced national lockdown was imposed to flatten the COVID-19 curve, aspects related to livelihood and financial security were affected for both the rural and tribal populations.

ABSTRACT

Sinonasal polyps are benign projections of edematous nasal mucosa lined by respiratory epithelium. Langerhans cells (LCs) belonging to the dendritic cell family located in respiratory epithelium are involved in antigen presentation and maintenance of local immunological homeostasis. This study aims to elucidate the morphology and distribution of CD1a positive LCs in normal nasal mucosa and compare the same with polypoid nasal mucosa by immunohistochemistry. Normal nasal mucosa (n = 20) was obtained from patients who underwent septoplasty for deviated nasal septum. Polypoid nasal mucosa (n = 22) was obtained from patients with chronic rhinosinusitis (CRS) or allergic fungal rhinosinusitis who underwent excision of nasal polyps. The tissues obtained were processed for immunohistochemistry and stained with CD1a-EP80 Rabbit monoclonal antibody. In the tissues studied, CD1a positive LCs were observed in both the epithelium and lamina propria. Different morphological subtypes of LCs were noted in the epithelium. The cells were distributed adjacent to walls of subepithelial capillaries and cysts. The median number of CD1a positive LCs was significantly higher in polypoid category (13.5 per mm2) as compared with normal nasal mucosa (2.5per mm2) (p = .001). Presence of CD1a positive LCs in polypoid nasal mucosa hints at a critical immunological role in the etiopathogenesis of nasal polyps.

ABSTRACT

BACKGROUND: The current situation in Afghanistan makes it likely that we are facing a new wave of Afghan refugees, warranting more knowledge about how to deal with mental health problems among them. This study aims to gain more knowledge on Explanatory Models (EM) of depression and post-traumatic stress disorders (PTSD) among Afghan refugees resettled in Norway. METHODS: We conducted six gender-separated, semi-structured focusgroup interviews based on vignettes with Afghan refugees (total N = 27). The vignettes described a fictional character with symptoms of either depression or PTSD symptoms in line with DSM-5 and ICD-10 criteria. RESULTS: The findings showed that EM varied with gender, age, generation, and migration stories. Participants suggested different potential causes, risk factors, and ways of managing symptoms of depression and PTSD depending on the context (e.g., in Norway vs. Afghanistan). In describing the causes of the depression/PTSD in the vignettes, females tended to emphasize domestic problems and gender issues while males focused more on acculturation challenges. The younger males discussed mostly traumatic experiences before and during flight as possible causes. CONCLUSION: The practice of condensing a single set of EMs within a group may not only be analytically challenging in a time-pressed clinical setting but also misleading. Rather, we advocate asking empathic questions and roughly mapping individual refugee patients' perceptions on causes and treatment as a better starting point for building trusting relationships and inviting patients to share and put into practice their expertise about their own lives.

ABSTRACT

BACKGROUND: Anterior Decompression and Fusion (ACDF) is a common surgery recommended for symptomatic cervical degenerative disc disease after failed conservative care. There is no consensus on the choice of implants, and it varies between surgeons. This study aims to analyse the early complications following ACDF performed using a standalone cage versus a Zero-P (Cage Screw - (CS)) construct for patients with cervical degenerative disc disease. METHODS: A total of 162 patients underwent an ACDF between August 2016 and July 2018. There were 83 patients (111 cervical disc levels) with standalone cage (SA) and 79 patients (111 cervical disc levels) with cage-screw (CS) fixation. There was no difference between the groups in terms of age, gender, and levels of surgery. The follow-up ranged from 2 months to 24 months. Complications, both clinical and radiological, were assessed between the groups. RESULTS: Both the SA and Zero-P (CS) groups were subdivided into single and multilevel surgery. Complications encountered in the SA group were temporary swallowing problems 10, hoarseness of voice 3, cage migration 1, delayed union 1, Horner's syndrome 1, cage subsidence 2. In the CS group swallowing problems 4, hoarseness of voice 4, CSF leak 1, recurrent symptoms 1. The observed difference in the incidence of complications between the groups did not reach statistical significance. Univariate analysis between the groups did not show any difference in the improvement of cervical sagittal balance, fusion rate, subsidence, and complications encountered. Multivariate logistic regression analysis for complications showed no difference between the groups when assessed for smoking, gender, age, Charlson comorbidity index, levels of surgery, fusion status, Odom score, or the type of implant. CONCLUSION: In this short-term study, the standalone (SA) cages showed no difference in their complication profile in comparison to a cage-screw construct for both single and multilevel ACDF. Standalone cages might be a cost-effective option without increased complication risks. Nevertheless, we propose a longer-term follow-up with a prospective randomized trial for further evaluation of this finding.

ABSTRACT

Purpose: By utilizing data from Estonia, Finland, and Norway, this study explores how the perceptions of personal and group realistic threats, namely perceived ethnic discrimination and economic insecurity among national majorities, predict their unwillingness to confront injustice on behalf of Russian-speaking minority groups. Background: Previous research on collective action to promote minorities' rights and social standing has focused either on minorities' own actions or factors promoting the willingness of majority group members to engage in collective action on behalf of minorities. In contrast, factors explaining the reluctance of majority group members to engage in collective action on behalf of minority groups have remained less explored. For example, studies have then ignored that the majority members may also feel threatened and may be economically insecure. Furthermore, the possible discrepancy between perceived personal vs. in-group's situation may influence majority group members' (un)willingness to confront injustice on behalf of a minority group. Method: We employed polynomial regression with response surface analysis to analyze data gathered among national majority members in three countries (N = 1,341). Results: Perceived personal and group realistic threats were associated with heightened unwillingness to confront injustice on behalf of the Russian-speaking minority. Furthermore, participants were more unwilling to confront injustice when they perceived more group than personal threat. Conclusion: We found that majority group members' (un)willingness to confront injustice on behalf of the minority is related to how secure they perceive their own and their group status. Our results contribute to previous research by pointing out the important drawbacks of majorities' support for minorities' wish for social change.

ABSTRACT

BACKGROUND: Population-based screening coverage for breast and cervical cancer screening in the community is inadequately reported in India. This study assessed screening rates, awareness, and other factors affecting screening, among rural women aged 25-60 years in Vellore, Tamil Nadu. METHODS: Women aged 25-60 years, from five randomly selected villages of a rural block were included in this cross-sectional study in Vellore, Tamil Nadu. Households were selected by systematic random sampling, followed by simple random sampling of eligible women in the house. A semi-structured questionnaire was used to assess screening practices, awareness, and other factors related to cervical and breast cancer. RESULTS: Although 43.8% and 57.9% were aware of the availability of screening for cervical and breast cancer respectively, screening rates were only 23.4% (95% confidence interval [CI]: 18.4-28.4%) and 16.2% (95% CI: 11.9-20.5%), respectively. Adequate knowledge (score of ≥50%) on breast cancer was only 5.9%, with 27.2% for cervical cancer. Only 16.6% of women had ever attended any health education program on cancer. Exposure to health education (breast screening odds ratio [OR]: 6.89, 95% CI: 3.34-14.21; cervical screening OR: 6.92, 95% CI: 3.42-14.00); and adequate knowledge (breast OR: 4.69, 95% CI: 1.55-14.22; cervix OR: 3.01, 95% CI: 1.59-5.68) were independently associated with cancer screening. CONCLUSION: Awareness and screening rates for breast and cervical cancer are low among rural women in Tamil Nadu, a south Indian state with comparatively good health indices, with health education being an important factor associated with screening practices.

ABSTRACT

Auxin is a key regulator of plant growth and development. Indole-3-acetic acid (IAA), a plant auxin, is mainly produced from tryptophan via indole-3-pyruvate (IPA) in both bryophytes and angiosperms. Angiosperms have multiple, well-documented IAA inactivation pathways, involving conjugation to IAA-aspartate (IAA-Asp)/glutamate by the GH3 auxin-amido synthetases, and oxidation to 2-oxindole-3-acetic acid (oxIAA) by the DAO proteins. However, IAA biosynthesis and inactivation processes remain elusive in lycophytes, an early lineage of spore-producing vascular plants. In this article, we studied IAA biosynthesis and inactivation in the lycophyte Selaginella moellendorffii. We demonstrate that S. moellendorffii mainly produces IAA from the IPA pathway for the regulation of root growth and response to high temperature, similar to the angiosperm Arabidopsis. However, S. moellendorffii exhibits a unique IAA metabolite profile with high IAA-Asp and low oxIAA levels, distinct from Arabidopsis and the bryophyte Marchantia polymorpha, suggesting that the GH3 family is integral for IAA homeostasis in the lycophytes. The DAO homologs in S. moellendorffii share only limited similarity to the well-characterized rice and Arabidopsis DAO proteins. We therefore suggest that these enzymes may have a limited role in IAA homeostasis in S. moellendorffii compared to angiosperms. We provide new insights into the functional diversification of auxin metabolic genes in the evolution of land plants.

ABSTRACT

Auxin is the first discovered plant hormone and is essential for many aspects of plant growth and development. Indole-3-acetic acid (IAA) is the main auxin and plays pivotal roles in intercellular communication through polar auxin transport. Phenylacetic acid (PAA) is another natural auxin that does not show polar movement. Although a wide range of species have been shown to produce PAA, its biosynthesis, inactivation and physiological significance in plants are largely unknown. In this study, we demonstrate that overexpression of the CYP79A2 gene, which is involved in benzylglucosinolate synthesis, remarkably increased the levels of PAA and enhanced lateral root formation in Arabidopsis. This coincided with a significant reduction in the levels of IAA. The results from auxin metabolite quantification suggest that the PAA-dependent induction of GRETCHEN HAGEN 3 (GH3) genes, which encode auxin-amido synthetases, promote the inactivation of IAA. Similarly, an increase in IAA synthesis, via the indole-3-acetaldoxime pathway, significantly reduced the levels of PAA. The same adjustment of IAA and PAA levels was also observed by applying each auxin to wild-type plants. These results show that GH3 auxin-amido synthetases can alter the ratio of IAA and PAA in plant growth and development.

ABSTRACT

Magnetic ferrite nanoparticles (MNPs) coated with biocompatible polymers capable of drug loading and release are fascinating nanostructures for delivering anti-cancer drugs. Herein, we report the synthesis and characterization of a novel ß-cyclodextrin-folate-tethered dextran polymer. Nickel-zinc ferrite nanoparticles are prepared and coated with the polymer to form a biocompatible hybrid magnetic nanocarrier. To establish the significance of folate unit of the polymer in anticancer activity, a similar derivatized polymer, i.e. ß-cyclodextrin-dextran conjugate without folate tether is used for comparison. The size of the hybrid MNPs is ∼20 nm, which is a size suitable for cancer drug targeting. The polymer-coated magnetic nanocarriers are soft ferromagnets as suggested by their narrow magnetic hysteresis loops. The anticancer drug camptothecin (CPT) is loaded on the magnetic nanocarriers. The drug loading efficiency is observed to be above 92%. The nanocarriers show sustained in vitro drug release for above 45 h. The in vitro cytotoxicity studies reveal that the loaded CPT retains its potency in the nanocarrier and the folate-tethered nanocarrier shows better anticancer activity than the one which does not carry a folate unit. The magnetic nanocarrier is suitable for magnetic field-guided drug transport, enhanced drug loading and release and folate receptor-mediated endocytotic uptake of drugs by cancer cells.

ABSTRACT

Technological advances, particularly in the capacity to support, replace or transplant failing organs, continue to challenge and refine our understanding of human death. Given the ability to reanimate organs before and after death, both inside and outside of the body, through reinstitution of oxygenated circulation, concepts related to death of organs (e.g. cardiac death) are no longer valid. This paper advances the rationale for a single conceptual determination of death related to permanent brain arrest, resulting from primary brain injury or secondary to circulatory arrest. The clinical characteristics of brain arrest are the permanent loss of capacity for consciousness and loss of all brainstem functions. In the setting of circulatory arrest, death occurs after the arrest of circulation to the brain rather than death of the heart. Correspondingly, any intervention that resumes oxygenated circulation to the brain after circulatory arrest would invalidate the determination of death.

ABSTRACT

This commentary highlights some of the strengths of the papers in this special issue focusing on how they advance acculturation research; how they link immigrant youth research with positive youth development and how they provide some insights into understanding how immigrant youth thrive in their adoptive societies. The commentary takes as its point of departure the prototypical research question for immigrant youth research within the perspective of positive youth development and the ultimate goals of acculturation research, i.e., to (i) promote positive psychological acculturation and the well-being of individuals and (ii) the attainment of harmonious intercultural relations among all groups in contact, and argues that the four papers fall short in addressing the second goal. The second goal is subsequently linked to multiculturalism and suggest that to do full justice to the prototypical research question, more attention should be directed to incorporating indicators of multiculturalism in acculturation research.

ABSTRACT

A binary mixture of oppositely charged colloids can be used to stabilize water-in-oil or oil-in-water emulsions. A Monte Carlo simulation study to address the effect of charge ratio of colloids on the stability of Pickering emulsions is presented. The colloidal particles at the interface are modeled as aligned dipolar hard spheres, with attractive interaction between unlike-charged and repulsive interaction between like-charged particles. The optimum composition (fraction of positively charged particles) required for the stabilization corresponds to a minimum in the interaction energy per particle. In addition, for each charge ratio, there is a range of compositions where emulsions can be stabilized. The structural arrangement of particles or the pattern formation at the emulsion interface is strongly influenced by the charge ratio. We find well-mixed isotropic, square, and hexagonal arrangements of particles on the emulsion surface for different compositions at a given charge ratio. The distribution of coordination numbers is calculated to characterize structural features. The simulation study is useful for the rational design of Pickering emulsifications wherein oppositely charged colloids are used, and for the control of pattern formation that can be useful for the synthesis of colloidosomes and porous shells derived thereof.

ABSTRACT

Although integration involves a process of mutual accommodation, the role of majority groups is often downplayed to passive tolerance, leaving immigrants with the sole responsibility for active integration. However, we show that common group identity can actively involve majority members in this process across five studies. Study 1 showed that common identity positively predicted support of integration efforts; Studies 2 and 3 extended these findings, showing that it also predicted real behavior such as monetary donations and volunteering. A decrease in modern racism mediated the relations across these studies, and Studies 4 and 5 further demonstrated that it indeed mediated these effects over and above acculturation expectations and color-blindness, which somewhat compromised integration efforts. Moreover, the last two studies also demonstrated that common, but not dual, groups motivated integration efforts. Common identity appears crucial for securing majorities' altruistic efforts to integrate immigrants and, thus, for achieving functional multiculturalism.

ABSTRACT

PURPOSE: Blackcurrant intake increases peripheral blood flow in humans, potentially by anthocyanin-induced vasodilation which may affect substrate delivery and exercise performance. We examined the effects of New Zealand blackcurrant (NZBC) extract on substrate oxidation, cycling time-trial performance and plasma lactate responses following the time-trial in trained cyclists. METHODS: Using a randomized, double-blind, crossover design, 14 healthy men (age: 38 ± 13 years, height: 178 ± 4 cm, body mass: 77 ± 9 kg, VO2max: 53 ± 6 mL kg(-1) min(-1), mean ± SD) ingested NZBC extract (300 mg day(-1) CurraNZ™ containing 105 mg anthocyanin) or placebo (PL, 300 mg microcrystalline cellulose M102) for 7 days (washout 14 days). On day 7, participants performed 30 min of cycling (3 × 10 min at 45, 55 and 65 % VO2max), followed by a 16.1 km time-trial with lactate sampling during a 20-min passive recovery. RESULTS: NZBC extract increased fat oxidation at 65 % VO2max by 27 % (P < 0.05) and improved 16.1 km time-trial performance by 2.4 % (NZBC: 1678 ± 108 s, PL: 1722 ± 131 s, P < 0.05). Plasma lactate was higher with NZBC extract immediately following the time-trial (NZBC: 7.06 ± 1.73 mmol L(-1), PL: 5.92 ± 1.58 mmol L(-1), P < 0.01). CONCLUSIONS: Seven-day intake of New Zealand blackcurrant extract improves 16.1 km cycling time-trial performance and increases fat oxidation during moderate intensity cycling.

ABSTRACT

We examined the effect of New Zealand blackcurrant (NZBC) extract on high-intensity intermittent running and postrunning lactate responses. Thirteen active males (age: 25 ± 4 yrs, height: 1.82 ± 0.07 m, body mass: 81 ± 14 kg, VO2max: 56 ± 4 ml·kg-1·min-1, vVO2max: 17.6 ± 0.8 km·h-1) performed a treadmill running protocol to exhaustion, which consisted of stages with 6 × 19 s of sprints with 15 s of low-intensity running between sprints. Interstage rest time was 1 min and stages were repeated with increasing sprint speeds. Subjects consumed capsuled NZBC extract (300 mg·day-1 CurraNZ; containing 105 mg anthocyanin) or placebo for 7 days (double-blind, randomized, crossover design, wash-out at least 14 days). Blood lactate was collected for 30 min postexhaustion. NZBC increased total running distance by 10.6% (NZBC: 4282 ± 833 m, placebo: 3871 ± 622 m, p = .02), with the distance during sprints increased by 10.8% (p = .02). Heart rate, oxygen uptake, lactate and rating of perceived exertion were not different between conditions for the first 4 stages completed by all subjects. At exhaustion, blood lactate tended to be higher for NZBC (NZBC: 6.01 ± 1.07 mmol·L-1, placebo: 5.22 ± 1.52 mmol·L-1, p = .07). There was a trend for larger changes in lactate following 15 min (NZBC: -2.89 ± 0.51 mmol·L-1, placebo: -2.46 ± 0.39 mmol·L-1, p = .07) of passive recovery. New Zealand blackcurrant extract (CurraNZ) may enhance performance in sports characterized by high-intensity intermittent exercise as greater distances were covered with repeated sprints, there was higher lactate at exhaustion, and larger changes in lactate during early recovery after repeated sprints to exhaustion.
