RESUMEN
The Peace Education Program, created in 2012, is a complementary program with potential to supplement official rehabilitation interventions offered in correctional centers. The program promotes "inner peace" as an innate and universal human resource, but whilst inner peace is a key concept in positive psychology and the Good Lives Model, there is a paucity of research regarding how to operationalize and evaluate this concept. The program had not previously been the subject of independent theoretically-informed research. Drawing on a mixed methods study conducted in Adelaide Women's Prison, this article explores the impact of the program on participants' learning regarding inner peace. Participants reported a greater understanding about inner peace, which they described as contributing to a stronger sense of their identity, enhanced self-esteem and increased self-regulation skills, resulting in reductions in impulsivity and reactive aggression. The quantitative data indicated there was a significant increase in participants' subjective ratings of inner peace before the program (M = 12.08) and post-program completion (M = 14.00) (p < .001). Growth in affect-regulation and anger-management skills may contribute to reductions in offending.
RESUMEN
BACKGROUND: Antimicrobial resistance (AMR) is promoted by inappropriate use and is a greater burden for low to middle income countries (LMIC) than high income countries (HIC). OBJECTIVE: This systematic review aimed to compare the awareness of inappropriate use related to AMR among medical doctors from LMIC and HIC using published knowledge, attitude and practice (KAP) studies. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, sequential systematic literature search of PubMed and Web of Science databases for articles published since inception up to June 1, 2022 for KAP studies involving medical doctors. Using fifteen KAP items related to promoting AMR, data on proportion of participants responding affirmatively was extracted and reported using means, ranges and 95% confidence intervals (CI). RESULTS: Forty-two studies met the inclusion criteria and involved 13,089 medical doctors from 11HIC and 21LMIC. All were cross-sectional studies, 71.4% involved non-probability sampling and 78.6% were of satisfactory quality. Knowledge items showed mean proportion of more medical doctors responding correctly. Similar affirmation trends were observed for attitude and prescribing practice items. Awareness appeared similar between medical doctors of the economic groups, except for a greater interest in training for LMIC (95.4%; 95%CI 93.0%, 97.9%) versus HIC (81.7%; 95%CI 65.6%, 97.9%). Countries with poor proportions were identified in both economic groups. CONCLUSION: For identified studies, trends suggest good awareness among medical doctors of the known inappropriate use and perceived threat of AMR, as well as prescribing practices to reduce the risk of AMR. Trends were similar across HIC and LMIC; however, countries with evidence of poor awareness exist in both economic groups.

Background: Oncology nurses are involved through the often protracted and potentially traumatic continuum of diagnosis and treatment of their patients, which places them at high risk of developing compassion fatigue. Aim: The aim of the study was to develop and implement an in-facility intervention to manage compassion fatigue among oncology nurses in Durban, South Africa. Setting: The study was conducted with oncology nurses at state, private (private health insurance) and non-governmental oncology facilities (Hospice). Methods: The Self-Care Intervention for Oncology Nurses was developed and implemented using action research with a mixed methods sequential explanatory design. It involved an integrative review, Professional Quality of Life (ProQOL) v 5 questionnaires (n = 83) and in-depth individual interviews (n = 8). Results: Developed from the findings of the integrative review, quantitative and qualitative data, the Self-Care Intervention for Oncology Nurses comprised three components, namely psycho-education on risks (booklet), practices of remembrance (remembrance tree) and support structures (support group and follow-up family call). Overall, the participants enjoyed reading the booklet and engaging in the support group. There were varied responses to the remembrance tree and hesitancy to partaking in the follow-up phone call. Conclusion: The developed intervention could encourage awareness of compassion fatigue amongst oncology nurses' engagement in self-care practices such as symbolic remembrance of patients and recognition of the value of support structures. Contribution: The intervention may assist oncology nurses in the provision of compassionate caring for their patients and potentially minimise compassion fatigue.
RESUMEN
Cases of suicidal hanging are a common death referred for medico-legal autopsy throughout the world. Although some advocate using postmortem computed tomography (PMCT) without traditional invasive autopsy (TIA) to investigate such deaths, others reject this approach. There is currently limited evidence to guide practice. In this context, the TIA reports and PMCT images of 50 cases of suspected suicidal hanging during an 11-month period were reviewed. The reviewers were blinded to the findings of the other modality. A Cohen's Kappa coefficient (K) was calculated to assess agreement between TIA and PMCT across a range of pertinent findings. This analysis demonstrated perfect agreement for identification of a ligature (K = 1.00) and a strong level of agreement for identification of a ligature suspension point (K = 0.832) but only a minimal level of agreement for overall ligature mark (K = 0.223). PMCT demonstrated a weak level of agreement for fractures of hyoid bone (K = 0.555) and thyroid cartilage (K = 0.538). Three probable fractures not identified at TIA were identified on PMCT. TIA was shown to be superior in the identification of intramuscular and laryngeal fracture-related haemorrhage/bruising whereas PMCT was superior to TIA in identifying body gas deposition. There was overall good correlation between the natural disease and trauma identified elsewhere in the body during the TIA and PMCT. The study demonstrates that PMCT can assist the investigation of suspected suicidal hangings. However, the accuracy of many findings is limited, and if it is used as an alternative to the TIA, potentially pertinent findings, such as fractures of the laryngeal cartilages, could be missed.

Social science research on health in South Africa tends to focus on illness and how to address health problems. Qualitative empirical research focussing on lay understandings and experiences of healthiness, or health discourses, in South Africa is fairly limited. This article addresses this gap by critically exploring how young South African adults used discourses of balance to make sense of what it means to be a healthy person and highlights the implications of these discourses for identity. Foucault's concepts of 'technologies of the self' and 'techniques of discipline' are discussed as a theoretical grounding for this paper. Data were collected from 20 in-depth semi-structured interviews, and analysed using Foucauldian discourse analysis. This paper will specifically explore a key discourse identified through the analysis: 'health as balance' and 2 interrelated sub-discourses which fall within it. Through this discourse, healthiness was constructed as requiring a broad focus on improving all aspects of one's life ('health as holistic') and the avoidance of any behaviours or emotions which could be classified as extreme ('health as moderation'). Constant, careful management of the self, or 'calibration', functions to both perpetuate a cycle of 'anxiety and control' and to obscure ways in which health discourses can be harmful or problematic.
RESUMEN
Most, if not all, peripheral immune cells in humans and animals express tyrosine hydroxylase (TH), the rate limiting enzyme in catecholamine synthesis. Since TH is typically studied in the context of brain catecholamine signaling, little is known about changes in TH production and function in peripheral immune cells. This knowledge gap is due, in part, to the lack of an adequately sensitive assay to measure TH in immune cells expressing lower TH levels compared to other TH expressing cells. Here, we report the development of a highly sensitive and reproducible Bio-ELISA to quantify picogram levels of TH in multiple model systems. We have applied this assay to monocytes isolated from blood of persons with Parkinson's disease (PD) and to age-matched, healthy controls. Our study unexpectedly revealed that PD patients' monocytes express significantly higher levels of TH protein in peripheral monocytes relative to healthy controls. Tumor necrosis factor (TNFα), a pro-inflammatory cytokine, has also been shown to be increased in the brains and peripheral circulation in human PD, as well as in animal models of PD. Therefore, we investigated a possible connection between higher levels of TH protein and the known increase in circulating TNFα in PD. Monocytes isolated from healthy donors were treated with TNFα or with TNFα in the presence of an inhibitor. Tissue plasminogen activator (TPA) was used as a positive control. We observed that TNFα stimulation increased both the number of TH+ monocytes and the quantity of TH per monocyte, without increasing the total numbers of monocytes. These results revealed that TNFα could potentially modify monocytic TH production and serve a regulatory role in peripheral immune function. The development and application of a highly sensitive assay to quantify TH in both human and animal cells will provide a novel tool for further investigating possible PD immune regulatory pathways between brain and periphery.
RESUMEN
Is it possible to slow the rate of ageing, or do biological constraints limit its plasticity? We test the 'invariant rate of ageing' hypothesis, which posits that the rate of ageing is relatively fixed within species, with a collection of 39 human and nonhuman primate datasets across seven genera. We first recapitulate, in nonhuman primates, the highly regular relationship between life expectancy and lifespan equality seen in humans. We next demonstrate that variation in the rate of ageing within genera is orders of magnitude smaller than variation in pre-adult and age-independent mortality. Finally, we demonstrate that changes in the rate of ageing, but not other mortality parameters, produce striking, species-atypical changes in mortality patterns. Our results support the invariant rate of ageing hypothesis, implying biological constraints on how much the human rate of ageing can be slowed.

Infectious disease is recognized as the greatest threat to the endangered chimpanzees made famous by the groundbreaking work of Dr. Jane Goodall at Gombe National Park (GNP), Tanzania. The permeable boundary of this small protected area allows for regular wildlife-human and wildlife-domestic animal overlap, which may facilitate cross-species transmission of pathogens and antimicrobial resistance. Few studies have examined the prevalence of antimicrobial resistance in wild ape populations. We used molecular techniques to investigate the presence of genes conferring resistance to sulfonamides (often used to treat diarrheal illness in human settings in this region) and tetracycline (used in the past-though much less so now) in fecal specimens from humans, domestic animals, chimpanzees, and baboons in and around GNP. We also tested stream water used by these groups. Sulfonamide resistance was common in humans (74%), non-human primates (43%), and domestic animals (17%). Tetracycline resistance was less common in all groups: humans (14%), non-human primates (3%), and domestic animals (6%). Sul resistance genes were detected from 4/22 (18%) of streams sampled. Differences in sul gene frequencies did not vary by location in humans nor in chimpanzees.
RESUMEN
Mononuclear macrophages derived from the bone marrow (myeloid cells) are key cellular components of the innate immune system in different organs. In this minireview, we are focused on both brain and blood macrophages, known as microglia and monocytes, respectively. We provide a succinct summary of the cells' functions under both normal and pathologic conditions, with particular reference to common neurodegenerative disorders, such as Alzheimer and Parkinson disease. SIGNIFICANCE STATEMENT: In this minireview, we aim to summarize available literature on microglial and myeloid involvement in CNS disease, directing the reader toward relevant and translatable interpretations of myeloid cell function in CNS health and neurodegeneration.

Baboons, members of the genus Papio, comprise six closely related species distributed throughout sub-Saharan Africa and southwest Arabia. The species exhibit more ecological flexibility and a wider range of social systems than many other primates. This article summarizes our current knowledge of the natural history of baboons and highlights directions for future research. We suggest that baboons can serve as a valuable model for complex evolutionary processes, such as speciation and hybridization. The evolution of baboons has been heavily shaped by climatic changes and population expansion and fragmentation in the African savanna environment, similar to the processes that acted during human evolution. With accumulating long-term data, and new data from previously understudied species, baboons are ideally suited for investigating the links between sociality, health, longevity and reproductive success. To achieve these aims, we propose a closer integration of studies at the proximate level, including functional genomics, with behavioral and ecological studies.

Hypothesis: In the care of acute myocardial infarction, ticagrelor attenuates post-ischemic myocardial damage and inhibits platelet activity to a greater extent than clopidogrel. Methods: Scholarly articles published in the last 10 years were compiled from a PubMed MeSH search focusing on acute coronary infarction and the antiplatelet therapies clopidogrel and ticagrelor. The databases used were PubMed, Google Scholar, Dynamed, and EBSCOhost. Eight articles were chosen based on subject matter related to the hypothesis, including cardioprotective effects, mortality benefits, platelet reactivity, angiographic effects, and electrocardiography changes. Results: Evidence from randomized clinical trials demonstrates that ticagrelor reduces infarct size, prevents remodeling, and reduces mortality rate after acute myocardial infarction to a greater extent than clopidogrel. However, some angiography studies show no difference between the two treatment regimes. Two articles show that ticagrelor is more effective in treating individuals with high platelet reactivity (HPR). In addition, there is some evidence of increased dyspnea and significant bleeding with ticagrelor. Discussion: Although there is growing evidence that ticagrelor is the better antiplatelet drug post-acute coronary infarction, more research needs to be done to determine the situations in which ticagrelor provides the optimal treatment regime in regards to cardioprotective effects, antiplatelet effects and an overall decrease in mortality. Conclusion: Ticagrelor was found to be superior to clopidogrel in relation to cardioprotective effects, mortality, and antiplatelet activity.
RESUMEN
PURPOSE: Healthiness is constructed, in Western culture, as a moral ideal or supervalue. This paper will interrogate the assumption that health and the pursuit of healthiness is always and unquestionably positive, by exploring how discourses of health and freedom interact to reinforce the current inequalities and detract from social transformation. METHOD: Twenty young South African adults were interviewed about their understandings and experiences of health. These discussions were analysed using Foucauldian discourse analysis. RESULTS: Participants constructed healthiness as facilitating the experience of freedom, while at the same time being dependent on a personal orientation towards freedom (as opposed to merely submitting to dominant health authorities). Freedom discourses also played a role in connecting health to neoliberal discourses idealizing economic productivity and hard work. Participants were able to construct a self that is active, productive, valuable, hopeful, and self-assured when talking about health using discourses of freedom. However, these discourses also functioned to moralise and idealise healthiness, which contributed to blaming poor health on its sufferers. CONCLUSION: Health/freedom discourses can further reinforce the neoliberal value of individual responsibility by constructing self-improvement and self-work as the solution to ill-health, thereby contributing to victim-blaming and weakening support for public health interventions.

The dopamine transporter (DAT) regulates dopamine neurotransmission via reuptake of dopamine released into the extracellular space. Interactions with partner proteins alter DAT function and thereby dynamically shape dopaminergic tone important for normal brain function. However, the extent and nature of these interactions are incompletely understood. Here, we describe a novel physical and functional interaction between DAT and the voltage-gated K+ channel Kv2.1 (potassium voltage-gated channel subfamily B member 1 or KCNB1). To examine the functional consequences of this interaction, we employed a combination of immunohistochemistry, immunofluorescence live-cell microscopy, co-immunoprecipitation, and electrophysiological approaches. Consistent with previous reports, we found Kv2.1 is trafficked to membrane-bound clusters observed both in vivo and in vitro in rodent dopamine neurons. Our data provide evidence that clustered Kv2.1 channels decrease DAT's lateral mobility and inhibit its internalization, while also decreasing canonical transporter activity by altering DAT's conformational equilibrium. These results suggest that Kv2.1 clusters exert a spatially discrete homeostatic braking mechanism on DAT by inducing a relative increase in inward-facing transporters. Given recent reports of Kv2.1 dysregulation in neurological disorders, it is possible that alterations in the functional interaction between DAT and Kv2.1 affect dopamine neuron activity.

BACKGROUND: Caring for cancer patients can take a toll on the emotional health of oncology nurses, which may lead to compassion fatigue, resulting in decreased quality of nursing care, absenteeism and decreased retention of staff. AIM: The aim of this study was to describe compassion fatigue from the perspective of oncology nurses. This study is part of a larger mixed-methods action research study to develop an in-facility intervention to manage compassion fatigue in oncology nurses. SETTING: This study was conducted at Durban, KwaZulu-Natal, South Africa. METHODS: The research setting comprised one state hospital (with oncology clinics and wards), a private hospital (with oncology wards) and a hospice in Durban, KwaZulu-Natal, South Africa. Semi-structured individual interviews (guided by Figley's Compassion Fatigue Process, 2005) were conducted with eight participants. Data were analysed using manifest content analysis. RESULTS: Five categories emerged from the data, namely, emotional connection, emotional fatigue, emotional loss, blurring boundaries and acceptance. CONCLUSION: The findings revealed that oncology nurses are affected emotionally in caring for their patients, thus making them prone to compassion fatigue. Oncology nurses need to acknowledge compassion fatigue and be able to self-reflect on how they are managing (both positively and negatively) with the stressors encountered in the oncology wards or units.
RESUMEN
In 1994, the Rwandan genocide claimed the lives of approximately 1 million Tutsi and moderate Hutu citizens. Systematic rape was a strategic component of the Hutu extremist plan to eradicate the Tutsi minority population. This involved collective and repeated sexual assaults with brutal violence, public humiliation, and torture. This article maps the ongoing psychological impact on Rwandan genocide rape survivors and identifies implications for international nursing practice. The research formalizes their narratives, identifying a number of interconnected elements that combine to produce myriad forms of chronic psychological suffering in the Rwandan context. This work in turn reveals the specific needs of these survivors that may be addressed by nursing. It allows nurses, as experts in managing the human responses to health and illness, to develop a more complete understanding of psychological suffering as it pertains to vulnerable populations during and in the wake of extreme social conflict. This clarifies the roles of nurse educators, clinicians, and policy advocates as key agents in providing genocide rape survivors with the resources and expertise needed to effectively manage their ongoing trauma.

Lipids influence powerfully the function of ion channels and transporters in two well-documented ways. A few lipids act as bona fide second messengers by binding to specific sites that control channel and transporter gating. Other lipids act nonspecifically by modifying the physical environment of channels and transporters, in particular the protein-membrane interface. In this short review, we first consider lipid signaling from this traditional viewpoint, highlighting innumerable Journal of General Physiology publications that have contributed to our present understanding. We then switch to our own emerging view that much important lipid signaling occurs via the formation of membrane domains that influence the function of channels and transporters within them, promote selected protein-protein interactions, and control the turnover of surface membrane.

Oesophagostomum sp. is a parasitic nematode that frequently infects wild chimpanzees. Although nodular lesions are commonly associated with infection, some wild chimpanzee populations seem to tolerate Oesophagostomum nodular lesions while those at Gombe and other sites suffer from associated morbidity and mortality. From August 2004 to December 2013, we examined demographic (i.e., age, sex) and individual correlates (i.e., fecal consistency, Oesophagostomum egg production) to Oesophagostomum-associated pathology in 14 individually recognized chimpanzees at Gombe Stream National Park, Tanzania. In addition, we characterized Oesophagostomum-associated pathology in 14 individual sympatric primates including baboons, colobus, and cercopithecid monkeys. In five chimpanzees, there was no evidence of any significant underlying disease aside from oesophagostomiasis to explain the thin condition or diarrhea. All five of these chimpanzees had moderate to numerous parasitic nodules. In general, nodules were more numerous in older chimpanzees. Three of four chimpanzees with the highest average Oesophagostomum egg counts in feces collected during the year prior to their death had numerous parasitic nodules at necropsy. In contrast, the four chimpanzees with the lowest egg counts had only moderate numbers of nodules. No association (P = 0.74) was noted between frequency of diarrhea in the year prior to death and the number of nodules noted at necropsy. Nodules were also present in all baboons examined documenting pathology associated with Oesophagostomum infection in wild baboons. In contrast, no lesions were noted in colobus or cercopithecid monkeys, although it is uncertain if they are infected as no fecal studies have been completed in these species to date at Gombe. Sequence of DNA isolated from nodules in chimpanzees matched (99%) Oesophagostomum stephanostomum. Further research is needed to identify the types of Oesophagostomum causing lesions in baboons and to determine if baboons suffer from these infections. Am. J.

During the 1994 Rwandan genocide, rape was widely used as a strategic weapon against Tutsi women. More than 20 years later, many of these women are still suffering devastating psychological, social, and physical effects of these experiences and remain in need of effective interventions that address their complex trauma. This article develops the theory of genocide rape trauma management as a conceptual framework for promoting the holistic health and recovery of female genocide rape survivors. A qualitative study using grounded theory explored the lived experiences of genocide rape survivors and led to the development of this model. The need for a contextually appropriate model is highlighted, with historical and current data regarding the Rwandan context and the experiences of genocide rape survivors. The research details the complex dynamics of emotional, physical, existential, and psychosocial sequelae related to genocide rape trauma, and how these interact with both local community and broader political attitudes toward survivors, as well as the serious interrelated economic challenges and limitations in current public health and welfare services. The research demonstrates the necessary elements of a holistic approach encompassing a synergistic combination of skilled psychological care, self-help strategies, collaborative support groups, community education, social reintegration, advocacy, accessible medical care, and economic empowerment. These interacting elements form the basis of the theory of genocide rape trauma management, offering an encompassing integrated framework that can be adapted to, and evaluated in, other similar contexts.
