Understanding barriers and facilitators to implementation of a patient safety bundle for pregnancy-related severe hypertension in 3 North Carolina outpatient clinics: a qualitative study.

Background: Pregnancy related hypertension is a leading cause of preventable maternal morbidity and mortality in the US, with consistently higher rates affecting racial minorities. Many complications are preventable with timely treatment, in alignment with the Alliance for Innovation on Maternal Health's Patient Safety Bundle ("Bundle"). The Bundle has been implemented successfully in inpatient settings, but 30% of preeclampsia-related morbidity occurs in outpatient settings in North Carolina.

A state-level analysis of macro-level factors associated with hospital readmissions.

Investigation of the factors that contribute to hospital readmissions has focused largely on individual level factors. We extend the knowledge base by exploring macrolevel factors that may contribute to readmissions. We point to environmental, behavioral, and socioeconomic factors that are emerging as correlates to readmissions.

Post-stroke limitations in daily activities: experience from a tertiary care hospital in Ethiopia.

Background: The disability of stroke patients remains an important global health problem; yet information on the extent of restriction from basic and instrumental activities of daily living is limited, particularly in lower-and middle-income (LMIC) countries. Therefore, we examined the issue under the caption, since it is the first step in planning several rehabilitation services.

Method: A facility-based cross-sectional study was done to assess the magnitude and predictors of post-stroke limitations in basic activities of daily living (BADL) using the Barthel Index (BI) scale and instrumental activities of daily living (IADL) using the Frenchay Activities Index (FAI) scale among patients who visited Tikur Anbessa Specialized Hospital in Addis Ababa, Ethiopia, Neurology Clinic from April-October, 2022.

Nipple-Sparing Gigantomastia Breast Reduction: A Systematic Review.

Introduction: There remains an unclear definition of the term "gigantomastia," with many studies using different parameters and measurements. Currently, the operative management and patient education for gigantomastia are outdated. The historical teaching that a free nipple graft is necessary in elongated pedicles to avoid nipple necrosis may not be factual.

Therapeutic high affinity T cell receptor targeting a KRAS cancer neoantigen.

Neoantigens derived from somatic mutations are specific to cancer cells and are ideal targets for cancer immunotherapy. KRAS is the most frequently mutated oncogene and drives the pathogenesis of several cancers. Here we show the identification and development of an affinity-enhanced T cell receptor (TCR) that recognizes a peptide derived from the most common KRAS mutant, KRAS, presented in the context of HLA-A*11:01.

Employers' perceptions of breastfeeding practice of employed mothers in Addis Ababa, Ethiopia: a qualitative study.

Background: The Ethiopian Demographic and Health Survey 2019 shows that 59% of children are exclusively breastfed for the first 6 months of life, then the rate decreases sharply with age. Nearly half of the Ethiopian labor force (46%) is comprised of women. This is encouraging since women's employment is one way of ensuring women's empowerment.

Regional and socio-economic disparity in use of insecticide-treated nets to prevent malaria among pregnant women in Kenya.

Background: Insecticide-treated net (ITN) use is among the most recommended strategies to prevent malaria in pregnancy. We analysed the regional and socio-economic patterns of ITN use among pregnant women in Kenya using data from the 2003, 2008 and 2014 Kenyan Demographic and Health Surveys (KDHSs).

Methods: Inequality was assessed using four dimensions: economic status, education, place of residence and region.

Food security status of patients with type 2 diabetes and their adherence to dietary counselling from selected hospitals in Addis Ababa, Ethiopia: A cross-sectional study.

Background: Even though adherence to dietary counselling for patients with diabetes is essential for improving health and preventing complications, access to an adequate and quality diet is challenging for patients living in a food-insecure household. The availability of data in this regard is limited in Ethiopia. Thus, this study assessed the food security status of patients with type 2 diabetes, their adherence to dietary counselling, and contributing factors at public hospitals in Addis Ababa, Ethiopia.

Level of exclusive breastfeeding and its enabling factors among lactating women who delivered in health facilities of Asosa town, Ethiopia: a cross sectional study.

Background: Despite the enormous benefit of exclusive breastfeeding (EBF) to mothers and infants, the practice of exclusive breastfeeding is globally low. In sub-Saharan Africa and Ethiopia, the prevalence of EBF stands at 35% and 59%, respectively. The low EBF practice in Ethiopia as well as in the studied region calls for further study and thus we studied the EBF practice in the study area since little is known about its current magnitude and factors influencing its practice for some programmatic improvements.

Barriers in adult vitamin D service provision by health care workers: a qualitative study in three ecologies of Ethiopia.

Background: Adult vitamin D deficiency, which is a public health problem in low-income countries, is correlated with increased mortality. Although health care workers (HCWs) in Ethiopia are educated on important minerals their counseling on the uses of vitamin D and its possible sources was not witnessed since their knowledge and practice is low. The main aim of this study is to explore barriers to good knowledge, positive attitude, and practice of health care providers on adult vitamin D.

Socioeconomic, urban-rural and sex-based inequality in infant mortality rate: evidence from 2013 Yemen demographic and health survey.

Background: The occurrence of Infant Mortality Rate (IMR) varied globally with most of the cases coming from developing countries including Yemen. The disparity in IMR in Yemen however, has not been well dealt and therefore we examined the IMR inequality based on the most reliable methodology in order to generate evidence-based information for some program initiatives in Yemen.

Methods: Based on the World Health Organization (WHO) Health Equity Assessment Toolkit (HEAT) software, we analyzed the inequality across the different inequality dimensions in Yemen.

The Impact of Surgeon Adherence to Preoperative Optimization of Hernia Repairs.

Background: At the patient level, optimizing risk factors before surgery is a proven approach to improve patient outcomes after hernia repair. However, nearly 25% of patients are not adequately optimized before surgery. It is currently unknown how surgeon-level adherence to preoperative optimization impacts postoperative outcomes.

Knowledge, attitude and practice of health care workers on measuring adult vitamin D level, diagnosis of deficiency, and management of consequent health conditions in three ecologies of Ethiopia: a cross-sectional study.

Background: Vitamin D is essential for health and its shortage exacerbates overall mortality. Health care workers (HCWs) need to educate on its uses and sources although studies indicate their low level of practice. The main aim of this study is therefore to assess the knowledge, attitude and practice of measuring adult vitamin D status, diagnosis of deficiency and managing health consequences among HCWs in Ethiopia.

Bispecific Targeting of PD-1 and PD-L1 Enhances T-cell Activation and Antitumor Immunity.

The programmed cell death protein 1 receptor (PD-1) and programmed death ligand 1 (PD-L1) coinhibitory pathway suppresses T-cell-mediated immunity. We hypothesized that cotargeting of PD-1 and PD-L1 with a bispecific antibody molecule could provide an alternative therapeutic approach, with enhanced antitumor activity, compared with monospecific PD-1 and PD-L1 antibodies. Here, we describe LY3434172, a bispecific IgG1 mAb with ablated Fc immune effector function that targets both human PD-1 and PD-L1.

Extent of and trends in inequalities in child stunting in Sierra-Leone from 2005 to 2013: evidence from demographic and health surveys and multiple indicator cluster surveys.

Background: Comprehensive assessment of stunting disparity in Sierra-Leone has not been done so far. We aimed to document extent and over time dynamics of inequality in stunting in Sierra-Leone using approaches that facilitate implementation of interventions aim to eliminate non-justified stunting disparity in the country.

Methods: The data for the study were derived from two rounds of the Sierra Leone Demographic and Health Survey conducted in 2008 and 2013, and two rounds of the Sierra Leone Multiple Indicator Cluster Survey done in 2005 and 2010.

Characterization of 7A5: A Human CD137 (4-1BB) Receptor Binding Monoclonal Antibody with Differential Agonist Properties That Promotes Antitumor Immunity.

The CD137 receptor plays a key role in mediating immune response by promoting T cell proliferation, survival, and memory. Effective agonism of CD137 has the potential to reinvigorate potent antitumor immunity either alone or in combination with other immune-checkpoint therapies. In this study, we describe the discovery and characterization of a unique CD137 agonist, 7A5, a fully human IgG1 Fc effector-null monoclonal antibody.

Knowledge, attitude, and practice towards epilepsy among religious cleric and traditional healers of Addis Ababa, Ethiopia.

Purpose: Understanding clerics and healers' knowledge, attitude, and practice towards epilepsy are crucial to identify the mechanisms of epilepsy stigma in Ethiopia. The objective of this study is to characterize the social and demographic determinants of knowledge, attitude, and practices of clerics and healers towards people with epilepsy in Addis Ababa, Ethiopia.

Methods: A total of 440 clerics and healers were interviewed by trained data collectors using a pretested structured questionnaire.

Bottlenecks and predictors of coverage and adherence outcomes for a micronutrient powder program in Ethiopia.

A theory-driven evaluation was conducted to assess performance of a trial to deliver micronutrient powder (MNP) through the Ethiopian Ministry of Health. We adapted an approach to coverage assessment, originally developed to identify bottlenecks in health service delivery, to examine sequential program outcomes and their correlates using cross-sectional survey data of caregivers of children 6-23 months (N = 1915). Separate multivariable Poisson regression models were used to estimate adjusted risk ratios of conceptually relevant determinants of coverage and adherence.

Anemia and its determinant of in-school adolescent girls from rural Ethiopia: a school based cross-sectional study.

Background: The rapid growth and changes that occur in adolescents increase the demand for macro and micronutrients and addressing their needs particularly in females would be an important step to break the vicious cycle of intergenerational malnutrition. Thus we evaluated the status of anemia and its anthropometric, dietary and socio demographic determinants in female adolescents, west Ethiopia.

Methods: A school based cross-sectional study was conducted among school going adolescent girls of Wayu Tuqa district, south west Ethiopia and a 3-stage random sampling technique was used to select study participants.

The Divergent Roles of Dietary Saturated and Monounsaturated Fatty Acids on Nerve Function in Murine Models of Obesity.

Neuropathy is the most common complication of prediabetes and diabetes and presents as distal-to-proximal loss of peripheral nerve function in the lower extremities. Neuropathy progression and disease severity in prediabetes and diabetes correlates with dyslipidemia in man and murine models of disease. Dyslipidemia is characterized by elevated levels of circulating saturated fatty acids (SFAs) that associate with the progression of neuropathy.

Chain length of saturated fatty acids regulates mitochondrial trafficking and function in sensory neurons.

Dyslipidemia associated with T2D leads to diabetic neuropathy, a complication characterized by sensory neuronal dysfunction and peripheral nerve damage. Sensory dorsal root ganglion (DRG) neurons are dependent on axonal mitochondrial energy production facilitated by mitochondrial transport mechanisms that distribute mitochondria throughout the axon. Because long-chain saturated FAs (SFAs) damage DRG neurons and medium-chain SFAs are reported to improve neuronal function, we evaluated the impact of SFA chain length on mitochondrial trafficking, mitochondrial function, and apoptosis.

Correction to: Discovery and preclinical characterization of the antagonist anti-PD-L1 monoclonal antibody LY3300054.

Unfortunately, after publication of this article [1], it was noticed that corrections to the legends of Figs. 1 and 2 were not correctly incorporated. The correct legends can be seen below.

Discovery and preclinical characterization of the antagonist anti-PD-L1 monoclonal antibody LY3300054.

Background: Modulation of the PD-1/PD-L1 axis through antagonist antibodies that block either receptor or ligand has been shown to reinvigorate the function of tumor-specific T cells and unleash potent anti-tumor immunity, leading to durable objective responses in a subset of patients across multiple tumor types.

Results: Here we describe the discovery and preclinical characterization of LY3300054, a fully human IgG1λ monoclonal antibody that binds to human PD-L1 with high affinity and inhibits interactions of PD-L1 with its two cognate receptors PD-1 and CD80. The functional activity of LY3300054 on primary human T cells is evaluated using a series of in vitro T cell functional assays and in vivo models using human-immune reconstituted mice.
