Epidemiology and Burden of Diabetic Foot Ulcer and Peripheral Arterial Disease in Korea

Information about the epidemiology of diabetic foot ulcer (DFU) with peripheral arterial disease (PAD) is likely to be crucial for predicting future disease progression and establishing a health care budget. We investigated the incidence and prevalence of DFU and PAD in Korea. In addition, we examined costs of treatments for DFU and PAD. This study was conducted using data from Health Insurance Review and Assessment Service from 1 January 2011 to 31 December 2016. The incidence of DFU with PAD was 0.58% in 2012 and 0.49% in 2016. The prevalence of DFU with PAD was 1.7% in 2011 to 1.8% in 2016. The annual amputation rate of DFU with PAD was 0.95% in 2012 and 1.10% in 2016. Major amputation was decreased, while minor amputation was increased. The direct cost of each group was increased, especially the limb saving group. which was increased from 296 million dollars in 2011 to 441 million dollars in 2016. The overall incidence of DFU with PAD was about 0.5% of total population in Korea, from 2012 to 2016. Furthermore, costs for treatments of diabetic foot ulcer are increasing, especially those for the limb saving group.
Prospective Predictors of Sexual Revictimization Among College Students

This study examined the prevalence rates of sexual violence revictimization during each year of college. In addition, the impact of key mental health concerns on these rates was investigated. Incoming first-year students at a large, urban university completed a survey about their exposure to incidences of sexual assault before college and about their mental health symptoms. During each subsequent spring semester, experiences of sexual assault and mental health symptoms were reassessed. The sample was limited to individuals who reported sexual assault for at least one time period (N = 3,294). More than 60% of individuals who endorsed an initial incident of sexual assault reported no subsequent incidences, leading to an overall revictimization rate of 39.5%. Rates of revictimization were higher for those identifying as women, as compared to men, and those identifying as White, as compared to those identifying as Asian or “other. ” Trauma-related distress and increased symptoms of alcohol use disorder (AUD) and depression were all related to a greater risk of experiencing revictimization. Given that experiencing an initial sexual assault greatly increases the risk of experiencing revictimization, and considering the notable prevalence rates of sexual assault on college campuses, it is imperative to examine trends in revictimization throughout the course of college. Examining factors that increase risk for experiencing revictimization is crucial to developing university-wide effective prevention and intervention efforts. In addition to the efforts to increase the reporting of incidences of sexual assault, universal programming efforts should also focus on factors that promote resilience in the face of sexual assault, such as reducing risky drinking behavior, increasing social support, and reducing stigma around the reporting of mental health symptoms.
The Relevance of Mass Spectrometry Analysis for Personalized Medicine through Its Successful Application in Cancer “Omics”

Mass spectrometry (MS) is an essential analytical technology on which the emerging omics domains; such as genomics; transcriptomics; proteomics and metabolomics; are based. This quantifiable technique allows for the identification of thousands of proteins from cell culture; bodily fluids or tissue using either global or targeted strategies; or detection of biologically active metabolites in ultra amounts. The routine performance of MS technology in the oncological field provides a better understanding of human diseases in terms of pathophysiology; prevention; diagnosis and treatment; as well as development of new biomarkers; drugs targets and therapies. In this review; we argue that the recent; successful advances in MS technologies towards cancer omics studies provides a strong rationale for its implementation in biomedicine as a whole.
Anopheles gambiae P450 reductase is highly expressed in oenocytes and in vivo knockdown increases permethrin susceptibility

We describe an in vivo model for investigation of detoxification mechanisms of the mosquito Anopheles gambiae, important for the development of malaria control programmes. Cytochrome P450s are involved in metabolic insecticide resistance and require NADPH cytochrome P450 reductase (CPR) to function. Here we demonstrate that the major sites of adult mosquito CPR expression are oenocytes, mid‐gut epithelia and head appendages. High CPR expression was also evident in Drosophila oenocytes indicating a general functional role in these insect cells. RNAi mediated knockdown drastically reduced CPR expression in oenocytes, and to a lesser extent in mid‐gut epithelia; the head was unaffected. These flies showed enhanced sensitivity to permethrin, demonstrating a key role for abdominal/mid‐gut P450s in pyrethroid metabolism, aiding the development of insecticides.
The splicing factor SRp20 modifies splicing of its own mRNA and ASF/SF2 antagonizes this regulation

SRp20 is a member of the highly conserved SR family of splicing regulators. Using a variety of reporter gene constructs, we show that SRp20 regulates alternative splicing of its own mRNA. Overexpression of SRp20 results in a reduction in the level of exon 4‐skipped SRp20 transcripts and activates the production of transcripts containing exon 4. These exon 4‐included transcripts encode a truncated protein lacking the C‐terminal RS domain. We provide evidence that SRp20 probably enhances the recognition of the otherwise unused, weak splice acceptor of exon 4. The recognition of exons with weak splice acceptor sites may be a general activity of SRp20. Unexpectedly, ASF/SF2, another member of the SR family, antagonizes the effect of SRp20 on SRp20 pre‐mRNA splicing and suppresses the production of the exon 4‐included form. Our results indicate that ASF/SF2 suppresses the use of the alternative exon 4, most likely by inhibiting the recognition of the splice donor of exon 4. These results demonstrate, for the first time, an auto‐regulatory activity of an SR protein which is antagonized by a second SR protein.
Lysophosphatidic Acid and Glutamatergic Transmission

Signaling through bioactive lipids regulates nervous system development and functions. Lysophosphatidic acid (LPA), a membrane-derived lipid mediator particularly enriched in brain, is able to induce many responses in neurons and glial cells by affecting key processes like synaptic plasticity, neurogenesis, differentiation and proliferation. Early studies noted sustained elevations of neuronal intracellular calcium, a primary response to LPA exposure, suggesting functional modifications of NMDA and AMPA glutamate receptors. However, the crosstalk between LPA signaling and glutamatergic transmission has only recently been shown. For example, stimulation of presynaptic LPA receptors in hippocampal neurons regulates glutamate release from the presynaptic terminal, and excess of LPA induce seizures. Further evidence indicating a role of LPA in the modulation of neuronal transmission has been inferred from animal models with deficits on LPA receptors, mainly LPA1 which is the most prevalent receptor in human and mouse brain tissue. LPA1 null-mice exhibit cognitive and attention deficits characteristic of schizophrenia which are related with altered glutamatergic transmission and reduced neuropathic pain. Furthermore, silencing of LPA1 receptor in mice induced a severe down-regulation of the main glutaminase isoform (GLS) in cerebral cortex and hippocampus, along with a parallel sharp decrease on active matrix-metalloproteinase 9. The downregulation of both enzymes correlated with an altered morphology of glutamatergic pyramidal cells dendritic spines towards a less mature phenotype, indicating important implications of LPA in synaptic excitatory plasticity which may contribute to the cognitive and memory deficits shown by LPA1-deficient mice. In this review, we present an updated account of current evidence pointing to important implications of LPA in the modulation of synaptic excitatory transmission.
HLA-DQB 1 – defined Genetic Susceptibility , Beta Cell Autoimmunity , and Metabolic Characteristics in Familial and Nonfamilial Insulin-dependent Diabetes Mellitus

Familial aggregation of insulin-dependent diabetes mellitus (IDDM) is a common phenomenon, but the reasons behind it are poorly understood. To investigate whether there is heterogeneity between familial and nonfamilial forms of IDDM we compared genetic, immunological, and clinical characteristics of diabetic children with and without an affected first-degree relative in a population-based series of Finnish children with IDDM. The frequencies of HLADQB1 genotypes known to be associated with high (DQB1*0302/0201) or moderate (*0302/x) IDDM risk in the Finnish population were increased, while the proportions of DQB1 genotypes associated with low or decreased risk for IDDM were reduced in the 121 familial cases as compared with the 574 nonfamilial cases (32.7 vs. 21.3%, 41.3 vs. 35.9%, 18.3 vs. 31.4%, and 7.7 vs. 11.4%, respectively; P 5 0.002). The frequencies and serum concentrations of islet cell antibodies, insulin autoantibodies, and antibodies to the 65-kD isoform of glutamic acid decarboxylase were similar at diagnosis in the familial and nonfamilial cases. The 31 first-affected cases in the multiple case families were younger at diagnosis than the nonfamilial cases (6.9 vs. 8.5 yr; P , 0.05). The 90 second-affected familial cases had less severe metabolic decompensation at diagnosis than either the first-affected familial or nonfamilial cases. In conclusion, familial aggregation of IDDM in Finland is at least partly explained by a higher frequency of IDDM susceptibility genes in families with multiple affected individuals. The lack of differences in autoantibody levels between the familial and nonfamilial cases indicates homogeneity rather than heterogeneity in the pathogenetic process of beta cell destruction. ( J. Clin. Invest. 1996. 98:2489–2495.)
Differential Pathogenic Th17 Profile in Mesenteric Lymph Nodes of Crohn's Disease and Ulcerative Colitis Patients

The drug targets IL23 and IL12 regulate pathogenicity and plasticity of intestinal Th17 cells in Crohn's disease (CD) and ulcerative colitis (UC), the two most common inflammatory bowel diseases (IBD). However, studies examining Th17 dysregulation in mesenteric lymph nodes (mLNs) of these patients are rare. We showed that in mLNs, CD could be distinguished from UC by increased frequencies of CCR6+CXCR3−RORγ+Tbet−CD4+ (Th17) memory T cells enriched in CD62Llow effector memory T cells (TEM), and their differentially expressed molecular profile. Th17 TEM cells (expressing IL17A, IL17F, RORC, and STAT3) displayed a higher pathogenic/cytotoxic (IL23R, IL18RAP, and GZMB, CD160, PRF1) gene signature in CD relative to UC, while non-pathogenic/regulatory genes (IL9, FOXP3, CTLA4) were more elevated in UC. In both CD and UC, IL12 but not IL23, augmented IFNγ expression in Th17 TEM and switched their molecular profile toward an ex-Th17 (Th1*)-biased transcriptomic signature (increased IFNG, and decreased TCF7, IL17A), suggesting that Th17 plasticity occurs in mLNs before their recruitment to inflamed colon. We propose that differences observed between Th17 cell frequencies and their molecular profile in CD and UC might have implications in understanding disease pathogenesis, and thus, therapeutic management of patients with IBD.
Challenges and barriers to optimising sedation in intensive care: a qualitative study in eight Scottish intensive care units

Objectives Various strategies to promote light sedation are highly recommended in recent guidelines, as deep sedation is associated with suboptimum patient outcomes. Yet, the challenges met by clinicians in delivering high-quality analgosedation is rarely addressed. As part of the evaluation of a cluster-randomised quality improvement trial in eight Scottish intensive care units (ICUs), we aimed to understand the challenges to optimising sedation in the Scottish ICU settings prior to the trial. This article reports on the findings. Design A qualitative exploratory design: We conducted focus groups (FG) with clinicians during the preintervention period. Setting and participants: Eight Scottish ICUs. Nurses, physiotherapists and doctors working in each ICU volunteered to participate. FG were recorded and verbatim transcribed and inserted in NVivo V.10 for analysis. Qualitative thematic analysis was undertaken to develop emergent themes from the patterns identified in relation to sedation practice. Ethical approval was secured by Scotland A Research ethics committee. Results Three themes emerged from the inductive analysis: (a) a recent shift in sedation practice, (b) uncertainty in decision-making and (c) system-level factors including the ICU environment, organisational factors and educational gaps. Clinicians were challenged daily to manage agitated or difficult-to-sedate patients in the era of a progressive mantra of ‘just sedate less’ imposed by the pain–agitation–delirium guidelines. Conclusions The current implementation of guidelines does not support behaviour change strategies to allow a patient-focused approach to sedation management, which obstructs optimum sedation–analgesia management. Recognition of the various challenges when mandating less sedation needs to be considered and novel sedation–analgesia strategies should allow a system-level approach to improve sedation–analgesia quality.

Epidemiology of cancers in Lahore, Pakistan, among children, adolescents and adults, 2010–2012: a cross-sectional study part 2

Objectives To estimate the cancer incidence by age group for the Lahore district population within the Punjab Cancer Registry (PCR), Pakistan. The average annual population of Lahore was 9.8 million in 2010–2012. This is a sequel to a study published earlier. Design A cross-sectional study. Setting The registry has 19 centres in Lahore reporting their data to the coordinating office located within the Shaukat Khanum Memorial Cancer Hospital and Research Center (SKMCH&RC), Lahore, Pakistan. Participants Data existing in the PCR database, based on a confirmed diagnosis of cancer from 1 January 2010 to 31 December 2012, among the Lahore residents, were reviewed. Outcome measures Cancer counts and the age-standardised incidence rates (ASIR) per 100 000 population were computed by gender, cancer site/type and age group (0–14, 15–19 and ≥20 years). Results Between 2010 and 2012, of the 15 840 new cancers diagnosed, 57% were in females. The ASIRs in age groups 0–14, 15–19 and ≥20 years, among females, were: 6.1, 8.4 and 170.7, respectively, and among males, 9.3, 12.2 and 104.5, respectively. The common diagnoses in children, adolescents and adults were: (1) among females: leukaemia: 2.2; bone tumour: 1.4 and breast cancer: 79.2, respectively, and (2) among males: leukaemia: 3.6; bone tumour: 2.4 and prostate cancer: 10.7, respectively. Conclusions The ASIR was higher in adult women than in men, but it was lower in girls and young women than their corresponding male counterparts. Leukaemia was the most common diagnosis in children and bone tumour in adolescents, regardless of gender. Among women, breast cancer and, in men, prostate cancer, were the leading cancer types, in adults. These estimates could be used for the expansion of health coverage in the region including setting-up low cost, diagnostic tests for early detection of cancers.
Current Status of Patient-Derived Ovarian Cancer Models

Ovarian cancer (OC) is one of the leading causes of female cancer death. Recent studies have documented its extensive variations as a disease entity, in terms of cell or tissue of origin, pre-cancerous lesions, common mutations, and therapeutic responses, leading to the notion that OC is a generic term referring to a whole range of different cancer subtypes. Despite such heterogeneity, OC treatment is stereotypic; aggressive surgery followed by conventional chemotherapy could result in chemo-resistant diseases. Whereas molecular-targeted therapies will become shortly available for a subset of OC, there still remain many patients without effective drugs, requiring development of groundbreaking therapeutic agents. In preclinical studies for drug discovery, cancer cell lines used to be the gold standard, but now this has declined due to frequent failure in predicting therapeutic responses in patients. In this regard, patient-derived cells and tumors are gaining more attention in precise and physiological modeling of in situ tumors, which could also pave the way to implementation of precision medicine. In this article, we comprehensively overviewed the current status of various platforms for patient-derived OC models. We highly appreciate the potentials of organoid culture in achieving high success rate and retaining tumor heterogeneity.
Comparison of 5‐Fluorouracil and CO2 Laser for Treatment of Vaginal Condylomata

Seventy nonpregnant women with extensive condylomata of the vagina were treated either with intravaginal 5-fluorouracil (5-FU) cream or the CO2 laser. Treatment results were correlated with the morphologic type of condylomata, ie, papillary acuminata (58 patients), and flat condylomata (12 patients). Ten and 31% of women with Condylomata acuminata had persistent disease within nine months after a single course of 5-FU and laser therapy, respectively. Total failure rates after a second either 5-FU or laser treatment were 3.4%. The failure rates for flat condylomata were 50 and 16.6% after 5-FU and laser treatment, respectively. Recurrences, defined as the development of new disease after a nine-month disease-free period were 7.4 and 10% for C acuminata after 5-FU and laser therapy, respectively. Twenty-five and 20% of women with flat condylomata treated respectively with 5-FU and the laser had recurrent disease. Acute urethrovulvar vaginitis occurred in 12.2% of the 5-FU-treated group, whereas complications were absent in those treated with the laser. Although the number of patients in each treatment arm was small and the patients were not randomized, intravaginal 5-FU therapy with protection of the vulva seems more cost effective for C acuminata in nonpregnant women than the laser, which requires general anesthesia. Flat condylomata are best managed by laser therapy. Refractory lesions successfully respond to laser-5-FU combination therapy.
Improving nursing students’ perspective taking, perceptions of humanness, and attitudes toward older adults

ABSTRACT Whereas prior work has examined the role of nursing courses in improving empathic skills and reducing dehumanization of older adults, little research has explored how perspective taking and perceptions of humanness of older adults acquired through nursing curricula predict attitudes toward this age group. Nursing students (N = 43) completed surveys at the beginning (Time 1) and end of gerontological coursework (Time 2). Perspective taking and perceived human nature and human uniqueness of older adults increased from Time 1 to Time 2. Perceived human nature of older adults was associated with more positive attitudes at the end of the semester, compared to the beginning. Improved perceptions of the human nature of older adults also predicted lower ageism at the end of the semester. Strategies for improving perspective taking and perceptions of humanness of older adults in nursing courses are discussed.
Does Consanguinity Protect Against Breast Cancer in Tunisian Population

Consanguinity is highly prevalent in many parts of the world. The highest consanguinity rates (20% to 50% of all marriages) occur in North Africa, the Middle East, Southwest Asia and Southern India. The aim of this study is to assess the effect of consanguineous marriages on the incidence of sporadic and familial breast cancer in Tunisia. We ascertained the rate of consanguineous marriage and the average coefficient of inbreeding among 155 Tunisian patients diagnosed with sporadic or familial breast cancer. The coefficient of inbreeding among all breast cancer patients was 0,007. No difference was observed for sporadic (F=0.008) vs familial breast cancer (F=0.007). The coefficient of inbreeding was significantly lower in the breast cancer group than in the Tunisian general population (0.0157). Considering the age of the patients, the level of inbreeding was lower among patients older than 50 (F=0.0027), while those younger than 50 exhibited a coefficient of inbreeding similar to that of the general population (F=0.01). The protective effect of consanguinity against breast cancer, particularly for patients older than 50 years, may be related to the absence of major factors involved in the onset of breast cancer at an early age. This protective effect may be also related to the contribution of recessive alleles of modifier or low-penetrance genes in the homozygous state.
Role of fine-needle aspiration cytology and core needle biopsy in diagnosing musculoskeletal neoplasms

Background: The management of musculoskeletal neoplasms requires an accurate diagnosis, histologic type, and degree of tumor differentiation. Aim: The present study was undertaken to compare the accuracy of fine-needle aspiration cytology (FNAC) and core needle biopsy (CNB) in the diagnosis of musculoskeletal tumors and further to compare the results with histopathological examination of surgical specimens. Grading of malignant tumors was also compared on these techniques. Materials and Methods: This prospective study was conducted on 50 patients with musculoskeletal neoplasms. Detailed history, clinical examination, and radiological investigations were undertaken. FNAC followed by CNB were performed in each case. The tumors were categorized as benign and malignant with a definitive histotype diagnosis. For malignant neoplasms, cytologic and histologic gradings were done into three grades. The sensitivity and specificity of FNAC and CNB were compared. Results: Of the 50 cases with musculoskeletal neoplasms, 32 (64%) were bone tumors and 18 (36%) were soft tissue tumors. The sensitivity of FNAC and CNB for categorizing bone tumors into benign and malignant was 94.7%. For soft tissue tumors, FNAC had a sensitivity of 90.9% and CNB had a sensitivity of 100%. The specificity of both the techniques, FNA and CNB for bone and soft tissue tumors was 100%. For malignant bone tumors, cytologic grade was concordant with CNB grade in 72.2% of the cases. Cytologic grade was concordant with the grade on CNB in 81.8% cases for malignant soft tissue neoplasms. Conclusion: FNAC and CNB alleviate the need for an open biopsy in diagnosing and grading musculoskeletal neoplasms, thus facilitating appropriate therapeutic intervention.
Arachidonic Acid Causes Cell Death through the Mitochondrial Permeability Transition

We have investigated the effects of arachidonic and palmitic acids in isolated rat liver mitochondria and in rat hepatoma MH1C1 cells. We show that both compounds induce the mitochondrial permeability transition (PT). At variance from palmitic acid, however, arachidonic acid causes a PT at concentrations that do not cause PT-independent depolarization or respiratory inhibition, suggesting a specific effect on the PT pore. When added to intact MH1C1 cells, arachidonic acid but not palmitic acid caused a mitochondrial PTin situ that was accompanied by cytochrome crelease and rapidly followed by cell death. All these effects of arachidonic acid could be prevented by cyclosporin A but not by the phospholipase A2 inhibitor aristolochic acid. In contrast, tumor necrosis factor α caused phospholipid hydrolysis, induction of the PT, cytochrome c release, and cell death that could be inhibited by both cyclosporin A and aristolochic acid. These findings suggest that arachidonic acid produced by cytosolic phospholipase A2 may be a mediator of tumor necrosis factor α cytotoxicity in situ through induction of the mitochondrial PT.
