Berom cultural beliefs and attitudes towards mental health problems in Nigeria: a mixed-methods study
Beliefs and attitudes are essential in mental health discourse. However, cultural beliefs and attitudes towards mental health problems (ATMHPs) among the Berom people of Nigeria are under-researched. The present studies made original contributions using the Cultural Identity Model (CIM) as predictors to investigate ATMHPs, and semi-structured interviews to further explain the potential impact of cultural beliefs on MHPs. In study-1, N = 140 participants responded to questionnaires on ATMHPs and were analysed using multivariate multiple regression in RStudio. Study-2 interviewed N = 13 participants (n = 7 laypeople; n = 6 practitioners). Interviews were recorded, transcribed and analysed thematically. Study-1 findings showed CIM as a non-significant predictor of ATMHPs. However, in study-2, four themes emerged: Cultural beliefs that MHPs are caused by spiritual forces; Berom indigenous preference for traditional healing; Christian religious healing in Berom communities; and Western-trained mental health practitioners' perception of lay service-users. The authors concluded that the Berom traditional and Christian religious healings are beneficial
Fast evaluation of appointment schedules for outpatients in health care
We consider the problem of evaluating an appointment schedule for outpatients in a hospital. Given a fixed-length session during which a physician sees K patients, each patient has to be given an appointment time during this session in advance. When a patient arrives on its appointment, the consultations of the previous patients are either already finished or are still going on, which respectively means that the physician has been standing idle or that the patient has to wait, both of which are undesirable. Optimising a schedule according to performance criteria such as patient waiting times, physician idle times, session overtime, etc. usually requires a heuristic search method involving a huge number of repeated schedule evaluations. Hence, the aim of our evaluation approach is to obtain accurate predictions as fast as possible, i.e. at a very low computational cost. This is achieved by (1) using Lindley's recursion to allow for explicit expressions and (2) choosing a discrete-time (slotted) setting to make those expression easy to compute. We assume general, possibly distinct, distributions for the patient's consultation times, which allows us to account for multiple treatment types, as well as patient no-shows. The moments of waiting and idle times are obtained. For each slot, we also calculate the moments of waiting and idle time of an additional patient, should it be appointed to that slot. As we demonstrate, a graphical representation of these quantities can be used to assist a sequential scheduling strategy, as often used in practice

âDisability and HIV in Africa: Breaking the barriers to sexual health careâ
Three decades in to the HIV pandemic, the issues affecting people with disabilities remains less known. Increasing attention has been given to this overlooked population when it comes to HIV prevention, treatment and care. This is related to the significant unmet sexual and reproductive health care needs facing people with disabilities worldwide. This article discusses the barriers to sexual health for people with disabilities in Africa, and presents an argument about how mainstream HIV prevention work and research does not adequately attend to the sorts of systemic barriers that exclude people with disabilities, which a more targeted, and critical approach could
The sexual and reproductive rights and benefit derived from sexual and reproductive health services of people with physical disabilities in South Africa: beliefs of non-disabled people
There is a body of theoretical work, and some empirical research, which suggests that non-disabled
people assume people with physical disabilities not to be suitable romantic partners, not have sexual
drives or desires, or not be sexually active. Access to sexual and reproductive health services for the
latter group is a challenge: it has been proposed that people with physical disabilities face barriers to
sexual health care access which are structural (such as inaccessible health care provider offices) as
well as social (such as health care providers suggesting that people with physical disabilities should
not procreate). The present paper explores non-disabled South Africansâ beliefs concerning the
degree to which individuals have sexual and reproductive rights, and benefit from sexual and
reproductive healthcare, for people with physical disabilities and people without disability. Using a
survey, we asked 1,989 South Africans to estimate the degree to which people with physical
disabilities and people without disability have sexual rights, and benefit from sexual and
reproductive healthcare services, respectively. Respondents were more likely to support the idea
that the population without disability were deserving of sexual rights compared to people with
physical disabilities. Respondents were also more likely to rate the degree to which people with
physical disability benefit from sexual and reproductive healthcare as less than that for people
without physical disabilities. These findings provide some of the first empirical support that nondisabled
people perceive people with physical disabilities as having fewer sexual and reproductive
rights, and deriving less benefit from sexual and reproductive health services, than the population
without disability. To have diminished sexual rights, and benefit less from sexual and reproductive
healthcare, we suggest, evinces a negation of the sexual and reproductive needs and capacity of
people with physical disabilities
Sympathomimetic effects of chronic methamphetamine abuse on oral health: a cross-sectional study
Background: Methamphetamine, a highly addictive sympathomimetic stimulant, is currently widely abused worldwide and has been associated with devastating effects on oral health, resulting in the term "meth mouth". However, "meth mouth" pathology is primarily based on case reports with a lack of systematic clinical evaluation. Therefore, we have conducted a systematic study to investigate (1) the pharmacological impact of methamphetamine on oral health with regard to saliva function, including the parameters saliva flow rate and total saliva production (ml/5 min) and the buffering capacity of saliva;(2) the contribution of the symptoms of bruxism and muscle trismus to potential oral health damage. Methods: We assessed the data of 100 chronic methamphetamine abusers and 100 matched-pair comparison participants. Primarily, we conducted an anamnesis with all methamphetamine abusers with regard to saliva dysfunctions, jaw clenching and pain in the temporomandibular joint. Subsequently, in the first part of the clinical enquiry, we tested the saliva flow rate and the total saliva production (ml/5 min) by using the sialometry method and the buffer capacity of saliva by determining the pH-value. In the second part of the clinical enquiry, we evaluated bruxism symptoms with respect to generalized tooth attrition, dentine exposure and visible enamel cracks and examined a potential muscle trismus by measuring the maximal opening of the mouth. Results: The majority of methamphetamine abusers reported a dry mouth (72 %) and jaw clenching (68 %). Almost half of all methamphetamine abusers experienced pain in the temporomandibular joint (47 %). With regard to the clinical findings, methamphetamine abusers showed significantly lower total saliva production (ml/5 min) (p 0.05). Conclusions: The sympathomimetic effects of chronic methamphetamine abuse may lead to dry mouth and extensive bruxism and therefore can increase the risk for caries decay, periodontal lesions and tooth wear. Furthermore, a significant decline of saliva buffer capacity in methamphetamine abusers may trigger the risk for dental erosions. Methamphetamine abusers and practitioners should be aware of these symptoms

Navigating the relational psychic economy of disability: The case of M
This paper presents a theoretically-informed psychosocial analysis of the case of M, a physically disabled man from South Africa. We use Mâs account as a platform from which to consider projection, melancholic suspension and grief, as these are played out in the negotiation of dependency in relationships for disabled people. Making use of a case study methodology, we examine the various strategies through which M manages those disability stereotypes which are ascribed to him, creating a picture of how ident ity is negotiated in the face of interpersonal dependency as well as disablist prejudice. A central proposition is that, for M, upholding relationships which bring much - needed assistance means caring for the emotional lives of his carers, in a manner which leaves him more vulnerable to internalizing identity insults, and less able to resist his own oppression. Employing a psychoanalytic frame, we suggest that the âmelancholic suspensionâ which some disabled people may be subject to, may lead to the necessity to âtake onâ certain projections, in the process of accessing much-needed care. As shall be seen, M maneuvers creatively through this relational realm by engaging in trade-offs between positive identity and physical need, employing strategies which include self-deprecation, the performance of mastery, playing with gender, and humor. With these and other techniques, he navigates the relational and psychic economy of his dependency
Reliability and validity of the Adolescent Stress Questionnaire in a sample of European adolescents--the HELENA study
BACKGROUND:
Since stress is hypothesized to play a role in the etiology of obesity during adolescence, research on associations between adolescent stress and obesity-related parameters and behaviours is essential. Due to lack of a well-established recent stress checklist for use in European adolescents, the study investigated the reliability and validity of the Adolescent Stress Questionnaire (ASQ) for assessing perceived stress in European adolescents.
METHODS:
The ASQ was translated into the languages of the participating cities (Ghent, Stockholm, Vienna, Zaragoza, Pecs and Athens) and was implemented within the HELENA cross-sectional study. A total of 1140 European adolescents provided a valid ASQ, comprising 10 component scales, used for internal reliability (Cronbach α) and construct validity (confirmatory factor analysis or CFA). Contributions of socio-demographic (gender, age, pubertal stage, socio-economic status) characteristics to the ASQ score variances were investigated. Two-hundred adolescents also provided valid saliva samples for cortisol analysis to compare with the ASQ scores (criterion validity). Test-retest reliability was investigated using two ASQ assessments from 37 adolescents.
RESULTS:
Cronbach α-values of the ASQ scales (0.57 to 0.88) demonstrated a moderate internal reliability of the ASQ, and intraclass correlation coefficients (0.45 to 0.84) established an insufficient test-retest reliability of the ASQ. The adolescents' gender (girls had higher stress scores than boys) and pubertal stage (those in a post-pubertal development had higher stress scores than others) significantly contributed to the variance in ASQ scores, while their age and socio-economic status did not. CFA results showed that the original scale construct fitted moderately with the data in our European adolescent population. Only in boys, four out of 10 ASQ scale scores were a significant positive predictor for baseline wake-up salivary cortisol, suggesting a rather poor criterion validity of the ASQ, especially in girls.
CONCLUSIONS:
In our European adolescent sample, the ASQ had an acceptable internal reliability and construct validity and the adolescents' gender and pubertal stage systematically contributed to the ASQ variance, but its test-retest reliability and criterion validity were rather poor. Overall, the utility of the ASQ for assessing perceived stress in adolescents across Europe is uncertain and some aspects require further examination.The HELENA Study takes place with the financial support of the European

Genetic alterations of the SUMO isopeptidase SENP6 drive lymphomagenesis and genetic instability in diffuse large B-cell lymphoma
SUMOylation is a post-translational modification of proteins that regulates these proteins' localization, turnover or function. Aberrant SUMOylation is frequently found in cancers but its origin remains elusive. Using a genome-wide transposon mutagenesis screen in a MYC-driven B-cell lymphoma model, we here identify the SUMO isopeptidase (or deconjugase) SENP6 as a tumor suppressor that links unrestricted SUMOylation to tumor development and progression. Notably, SENP6 is recurrently deleted in human lymphomas and SENP6 deficiency results in unrestricted SUMOylation. Mechanistically, SENP6 loss triggers release of DNA repair- and genome maintenance-associated protein complexes from chromatin thereby impairing DNA repair in response to DNA damages and ultimately promoting genomic instability. In line with this hypothesis, SENP6 deficiency drives synthetic lethality to Poly-ADP-Ribose-Polymerase (PARP) inhibition. Together, our results link SENP6 loss to defective genome maintenance and reveal the potential therapeutic application of PARP inhibitors in B-cell lymphoma
