Real-time PCR versus traditional and Nano-based ELISA in early detection of murine trichinellosis.

Trichinellosis is a serious foodborne zoonosis. It poses a serious risk to public health worldwide. Early serological diagnosis of trichinellosis is influenced by an immunological 'silent' phase following infection. This highlights the necessity for developing sensitive diagnostic approaches to be employed when antibodies cannot be detected. In this work, the validity of traditional ELISA, Nano-ELISA and real time polymerase chain reaction (PCR) were evaluated in early diagnosis of Trichinella spiralis. Swiss albino mice were orally infected with 100 and 300 muscle larvae/mouse. Mice were sacrificed 4, 6, 8, 10, 15, and 28 days post-infection (dpi). Blood samples were tested for circulating antigen by traditional ELISA and Nano-ELISA using anti-rabbit polyclonal IgG conjugated with AgNPs and for Rep gene by SYBR green real-time PCR. Rep gene detection by SYBR green real-time PCR could detect T. spiralis with 100% sensitivity in the mild infection group at 8 dpi, while in the severe infection group it reached 100% sensitivity at 4 dpi. Nano-ELISA could detect T. spiralis circulating antigen from 4 dpi in both mild and severe infection and reached 100% sensitivity at 8 dpi and 6 dpi in mild and severe infection, respectively. However, traditional ELISA could detect T. spiralis circulating antigen from 6 dpi and reached maximum sensitivity at 15 dpi in the mild infection group, while in the severe infection group detection began at 4 dpi and reached 100% sensitivity at 8 dpi. Nano-ELISA and real time PCR, using Rep gene, are useful tools for the detection of early T. spiralis infection even in its mild infection state.

Knowledge and Compliance with Malaria National Treatment Guidelines among Primary Health Care Workers in a Rural Area in Northern Nigeria.

BACKGROUND: Knowledge and compliance with malaria treatment guidelines are among the major issues affecting treatment outcome for malaria in Nigeria. Primary health care (PHC) facilities are the first point of contact with the national health system for patients with malaria and other diseases. OBJECTIVE: This study assessed the knowledge and compliance with malaria National Treatment Guidelines (NTG) among PHC workers in Lere local government area of Kaduna State, North western Nigeria. METHODS: This was a descriptive cross-sectional study conducted among 42 community health workers. The total population of all eligible participants was used for subject selection. Data were analysed with SPSS IBM version 25.0 and STATA/SE 12. The level of statistical significance p-value was set at p<0.05. RESULTS: The mean age of the respondents was 38.02±9.23 years. Majority of the respondents were males (25; 59.5%) and community health extension workers (CHEWs) (24; 57.1%). Almost one-third (28.6%) of the PHC workers had poor knowledge of the recommendations of the NTG for malaria, while 14.3% had poor compliance with the NTG. Bivariate analysis showed a significant relationship between older age and good knowledge of the NTG ( χ2 =0.03, p=0.04). Multivariate analysis further revealed that the odds for poor knowledge of NTG was 40% higher among CHEWs compared to other health workers (AOR=1.40, 95% CI=0.25-7.93). The odds for good knowledge was lower by 55% among those who had practiced for <10 years compared to >10 years (OR=0.45, 95% CI=0.06-3.32). CONCLUSION: Poor knowledge and compliance to malaria NTG were commoner among lower cadre (CHEWs) staff with relatively fewer years in PHC practice. There is a need for training, retraining and equitable distribution of the NTG to ensure access and also improve knowledge and utilisation of the NTG for malaria by rural PHC workers.

CONTEXTE: La connaissance et le respect des directives de traitement du paludisme sont parmi les principaux problèmes qui affectent les résultats du traitement du paludisme au Nigéria. Les établissements de soins de santé primaires (SSP) sont le premier point de contact avec le système national de santé pour les patients atteints de paludisme et d'autres maladies. OBJECTIF DE L'ÉTUDE: Cette étude a évalué les connaissances et le respect des directives nationales de traitement du paludisme (NTG) parmi les travailleurs des SSP dans la zone de gouvernement local de Lere de l'État de Kaduna, dans le nord-ouest du Nigeria. MÉTHODES: Il s'agit d'une étude descriptive transversale menée auprès de 42 agents de santé communautaires. La population totale de tous les participants éligibles a été utilisée pour la sélection des sujets. Les données ont été analysées avec SPSS IBM version 25.0 et STATA/SE 12. Le niveau de signification statistique a été fixé à p<0,05. RÉSULTATS: L'âge moyen des personnes interrogées était de 38,02±9,23 ans. La majorité des personnes interrogées étaient des hommes (25 ; 59,5%) et des agents de vulgarisation en santé communautaire (24 ; 57,1%). Près d'un tiers (28,6 %) des agents de santé publique connaissaient mal les recommandations de la NTG pour le paludisme, tandis que 14,3 % ne respectaient pas la NTG. L'analyse bivariée a montré une relation significative entre l'âge avancé et la bonne connaissance du NTG ( χ2=0,03, p=0,04). L'analyse multivariée a également révélé que la probabilité d'une mauvaise connaissance de la NTG était 40% plus élevée chez les CHEW que chez les autres agents de santé (AOR=1,40, 95% CI=0,25-7,93). La probabilité d'une bonne connaissance était inférieure de 55% chez ceux qui avaient pratiqué pendant <10 ans par rapport à >10 ans (OR=0,45, 95% CI=0,06-3,32). CONCLUSION: Le manque de connaissances et d'observance des NTG sur le paludisme était plus fréquent parmi le personnel des cadres inférieurs (CHEWs) ayant relativement moins d'années de pratique dans les soins de santé primaires. Il est nécessaire de former, de recycler et de distribuer équitablement les NTG pour garantir l'accès et améliorer la connaissance et l'utilisation des NTG pour le paludisme par les travailleurs des SSP en milieu rural. Mots clés: Connaissance, Observance, Personnel de soins de santé primaires, Directives, Paludisme.

Ginger and its active compounds in cancer therapy: From folk uses to nano-therapeutic applications.

Ginger is a spice that is renowned for its characteristic aromatic fragrance and pungent taste, with documented healing properties. Field studies conducted in several Asian and African countries revealed that ginger is used traditionally in the management of cancer. The scientific community has probed into the biological validation of its extracts and isolated compounds including the gingerols, shogaols, zingiberene, and zingerone, through in-vitro and in-vivo studies. Nonetheless, an updated compilation of these data together with a deep mechanistic approach is yet to be provided. Accordingly, this review highlights the mechanisms and therapeutics of ginger and its bioactive compounds focused on a cancer context and these evidence are based on the (i) cytotoxic effect against cancer cell lines, (ii) enzyme inhibitory action, (iii) combination therapy with chemotherapeutic and phenolic compounds, (iv) possible links to the microbiome and (v) the use of nano-formulations of ginger bioactive compounds as a more effective drug delivery strategy in cancer therapy.

Comparative Study Among Lactophenol Blue, Lactophenol Solution and Proteinase-K Lytic Solution for Rostellar Hooks Morphometry of Echinococcus Granulosus Protoscolices.

Echinococcus granulosus is a tapeworm whose life cycle includes dogs and other canines as final hosts, while domestic and wild ungulates act as intermediate hosts for the tissue-invading larval stage (metacestode). E. granulosus has a worldwide geographical distribution. Protoscolices and rostellar hooks of E. granulosus are useful for diagnosis and rostellar hook morphometric features may be useful to discriminate E. granulosus and related species. The present study was aimed to determine a more suitable lytic solution and to obtain a clearest vision for performing morphometric studies on the rostellar hooks of E. granulosus protoscolices. Five fertile hydatid cyst samples were collected from sheep in Kirkuk slaughterhouse, Iraq, during June of 2015. According to the results of the present study, proteinase-K lytic solution is the best approach in morphometric analysis to get a clear vision of rostellar hooks and a safer usage in comparison with solutions containing lactophenol (lactophenol, lactophenol blue).

Cholera Epidemic - Lusaka, Zambia, October 2017-May 2018.

On October 6, 2017, an outbreak of cholera was declared in Zambia after laboratory confirmation of Vibrio cholerae O1, biotype El Tor, serotype Ogawa, from stool specimens from two patients with acute watery diarrhea. The two patients had gone to a clinic in Lusaka, the capital city, on October 4. Cholera cases increased rapidly, from several hundred cases in early December 2017 to approximately 2,000 by early January 2018 (Figure). In collaboration with partners, the Zambia Ministry of Health (MoH) launched a multifaceted public health response that included increased chlorination of the Lusaka municipal water supply, provision of emergency water supplies, water quality monitoring and testing, enhanced surveillance, epidemiologic investigations, a cholera vaccination campaign, aggressive case management and health care worker training, and laboratory testing of clinical samples. In late December 2017, a number of water-related preventive actions were initiated, including increasing chlorine levels throughout the city's water distribution system and placing emergency tanks of chlorinated water in the most affected neighborhoods; cholera cases declined sharply in January 2018. During January 10-February 14, 2018, approximately 2 million doses of oral cholera vaccine were administered to Lusaka residents aged ≥1 year. However, in mid-March, heavy flooding and widespread water shortages occurred, leading to a resurgence of cholera. As of May 12, 2018, the outbreak had affected seven of the 10 provinces in Zambia, with 5,905 suspected cases and a case fatality rate (CFR) of 1.9%. Among the suspected cases, 5,414 (91.7%), including 98 deaths (CFR = 1.8%), occurred in Lusaka residents.

Efficacy and Safety of Simeprevir or Daclatasvir in Combination With Sofosbuvir for the Treatment of Hepatitis C Genotype 4 Infection.

INTRODUCTION: The combination of sofosbuvir (SOF) with simeprevir (SMV) or daclatasvir (DCV) is very effective in treating hepatitis C virus (HCV) infection, particularly genotype (GT) 1. However, the data on GT4 are very limited. We aimed to determine the efficacy and safety of SOF in combination with either SMV or DCV in GT4-infected patients. PATIENTS AND METHODS: In this real life, prospective, observational study, HCV (GT4) patients (n=96) were evaluated in 2 groups on the basis of the 12-week treatment regimen they received. Group 1 (n=56) patients were treated with SOF and SMV±ribavirin (RBV), whereas group 2 patients were treated with SOF and DCV±RBV (n=40). The primary efficacy endpoint was sustained virologic response 12, whereas the primary safety endpoint was drug discontinuation or occurrence of grade 3/4 adverse events. RESULTS: The mean age was 49±14.6 years (59.4% men). Cirrhosis was present in 53.6% and 35.0% of groups 1 and 2, respectively, whereas 27 patients (48.2%) in group 1 and 21 patients (52.5%) in group 2 had failed prior interferon-based treatment. The median pretreatment HCV-RNA log10 was 6.1 (3.6 to 7.0) and 6.0 (3.6 to 7.2) IU/mL in groups 1 and 2, respectively. RBV was given to 17 patients (30.4%) in group 1 and 2 patients (5%) in group 2. All patients achieved sustained virologic response 12 (100%). Adverse events occurred in 32% of patients (grade 1 and 2), but none discontinued treatment. One patient died in the SMV group (not related to treatment). CONCLUSIONS: SMV/SOF or DCV/SOF combinations are safe and highly effective in HCV-GT4 treatment. Cirrhosis and failure of prior interferon-based treatment did not influence treatment response.

Discrimination and Depressive Symptoms Among Black American Men: Moderated-Mediation Effects of Ethnicity and Self-Esteem.

Discrimination is related to depression and poor self-esteem among Black men. Poorer self-esteem is also associated with depression. However, there is limited research identifying how self-esteem may mediate the associations between discrimination and depressive symptoms for disparate ethnic groups of Black men. The purpose of this study was to examine ethnic groups as a moderator of the mediating effects of self-esteem on the relationship between discrimination and depressive symptoms among a nationally representative sample of African American (n = 1201) and Afro-Caribbean American men (n = 545) in the National Survey of American Life. Due to cultural socialization differences, we hypothesized that self-esteem would mediate the associations between discrimination and depressive symptoms only for African American men, but not Afro-Caribbean American men. Moderated-mediation regression analyses indicated that the conditional indirect effects of discrimination on depressive symptoms through self-esteem were significant for African American men, but not for Afro-Caribbean men. Our results highlight important ethnic differences among Black men.

Dietary habits and physical activity levels in Jordanian adolescents attending private versus public schools.

The present study examined differences in dietary habits and physical activity levels between students attending private and public high schools in Jordan. A total of 386 secondary-school males and 349 females aged 14-18 years were randomly recruited using a multistage, stratified, cluster sampling technique. Dietary habits and physical activity level were self-reported in a validated questionnaire. The prevalence of obesity was significantly higher among adolescents in private (26.0%) than in public schools (16.7%). The frequency of breakfast intake was significantly higher among adolescents in private schools, whereas French fries and sweets intake was significantly higher in public schools. Television viewing showed a significant interaction with school type by sex. A higher rate of inactivity was found among students attending private schools. Despite a slightly better overall dietary profile for students in private schools, they had a higher rate of overweight and obesity compared with those in public schools.

The Role of Interproximal Reduction (IPR) in Clear Aligner Therapy: A Critical Analysis of Indications, Techniques, and Outcomes.

Interproximal reduction (IPR) has become a standard practice in orthodontic treatment, particularly in the clear aligner therapy. It became an integral part of the digital plan when using clear aligners. Given the irreversible nature of IPR, precise planning and performance is essential. This article aims to analyze and summarize the existing literature on IPR in the context of clear aligners. The goal is to help clinicians to gain essential knowledge for safely and effectively navigating IPR. The review critically examines different perspectives found in the literature, covering indications, methods, and outcomes. Topics exploring the impact of IPR on treatment outcomes include space gaining, addressing tooth size discrepancies, tooth shape adjustments, resolving malocclusion, and enhancing aesthetics. Emphasizing precision of the procedure by the clinician and awareness of contraindications, the article also discusses the impact of IPR on patients. This includes considerations like increased pulp temperature, susceptibility to cavities due to changes in enamel roughness, effects on soft tissues, and post-IPR tooth sensitivity.

Fractional modeling of drug diffusion from cylindrical tablets based on Fickian and relaxed approaches with in vivo validation.

Mathematical simulation of drug diffusion is a significant tool for predicting the bio-transport process. Moreover, the reported models in the literature are based on Fick's approach, which leads to an infinite propagation speed. Consequently, it is essential to construct a mathematical model to represent the diffusion processes for estimating drug concentrations at different sites and throughout the circulation. Thus, in this article, the diffusion process is employed to propose three models for estimating the drug release from multi-layer cylindrical tablets. A fractional model is presented based on Fick's approach, while classical and fractional Cattaneo models are presented using the relaxed principle. Various numerical methods are used to solve the specified problem. The numerical scheme's stability and convergence are demonstrated. Drug concentration and mass profiles are presented for the tablet and the external medium and compared with the in vivo plasma profiles. The results show the efficiency and precision of the proposed fractional models based on the fourth-order weighted-shifted Grünwald-Letnikov difference operator approximation. These models are compatible with the in vivo data compared with the classical Fick's one.

Evaluation of in vivo and ex vivo pre-treated bone marrow-derived mesenchymal stem cells with resveratrol in streptozotocin-induced type 1 diabetic rats.

OBJECTIVES: To compare the therapeutic potential of rat bone marrow-derived mesenchymal stem cells (BM-MSCs) preconditioned ex-vivo with resveratrol (MCR) and BM-MSCs isolated from resveratrol-pre-treated rats (MTR) in type-1 diabetic rats. METHODS: Type-1 diabetes was induced by a single streptozotocin injection (50 mg/kg; ip) in 24 rats. Following the confirmation of T1DM, diabetic rats were randomly divided into four groups: diabetic control (DC), diabetic rats treated with insulin subcutaneous (7.5 IU/kg/day), diabetic rats treated with MCR cells (3 × 106cells/rat, intravenous) and diabetic rats treated with MTR cells (3 × 106cells/rat, intravenous). Rats were sacrificed 4 weeks following cellular transplantation. KEY FINDINGS: Untreated diabetic rats suffered from pancreatic cell damage, had high blood glucose levels, increased apoptotic, fibrosis, and oxidative stress markers and decreased survival and pancreatic regeneration parameters. Both MSCs preconditioned ex-vivo with RES and MSCs isolated from rats pre-treated with RES homed successfully in injured pancreas and showed therapeutic potential in the treatment of STZ-induced T1DM. MCR cells showed better efficiency than MTR cells. CONCLUSIONS: The pre-conditioning of BM-MSCs with resveratrol may be a promising therapeutic possibility in T1DM. Resveratrol-preconditioned BM-MSCs encouraged effects almost comparable to that of exogenous insulin with the advantages of cured pancreas and restored islets not attained by insulin.

Pembrolizumab-Induced Broken Heart Syndrome, Pneumonitis, and Hypophysitis Occurring Concurrently; A Deadly Triad.

Immune checkpoint inhibitors are novel medications used to treat a wide range of solid organ tumors and work by stimulating the cellular immune response. With their increasing use, more and more multiorgan side effects are reported in the literature. Prompt recognition of these findings is vital for the safe clinical use of these agents. Most side effects are immune-mediated injury, and the treatment involves stopping the ICI drug and systemic steroids. We report a case of a 72-year-old female treated with pembrolizumab monotherapy for non-small cell lung cancer. She presented for dyspnea and generalized weakness after the second session of pembrolizumab. She was found to have a triad of Takotsubo cardiomyopathy, hypophysitis, and pneumonitis. The patient was discharged home on steroids and heart failure treatment with the discontinuation of further sessions of pembrolizumab.

A Rare Association: Non-ST Elevation Myocardial Infarction (NSTEMI) Secondary to Respiratory Syncytial Virus (RSV) Infection.

We present a case report on a rare association between non-ST elevation myocardial infarction (NSTEMI) and respiratory syncytial virus (RSV) infection in a patient with no traditional risk factors for cardiovascular disease (CVD) including a family history of premature coronary artery disease (CAD). While RSV is commonly known for its respiratory manifestations, it has been increasingly recognized as a cause of significant morbidity and mortality in adults, particularly those with underlying comorbidities. However, the association between RSV infection and NSTEMI, especially in patients without traditional risk factors, remains relatively unexplored. Our case involves a 31-year-old healthy adult who presented with progressive exertional chest pain and flu-like symptoms. Electrocardiogram (EKG) changes and elevated troponin levels indicated NSTEMI. Laboratory tests confirmed RSV infection. Angiography revealed significant coronary artery disease requiring percutaneous coronary intervention. This case highlights the need for healthcare professionals to be aware of the potential cardiovascular (CV) complications associated with RSV infection, even in patients without traditional risk factors. It expands our understanding of viral respiratory infections as potential triggers for acute coronary syndromes (ACS) and emphasizes the importance of considering RSV infection in the differential diagnosis of NSTEMI, especially in young otherwise healthy individuals. Further research is warranted to explore the underlying mechanisms and develop preventive strategies for RSV-related cardiovascular complications.

Arrhythmogenic Left Ventricular Cardiomyopathy Associated With a Phospholamban Gene Mutation in a Young Female: A Case Report and Literature Review.

Arrhythmogenic cardiomyopathy (ACM) is a myocardium disease characterized by phenotypic features of myocardial scarring due to fibrofatty myocardial replacement often associated with global or regional ventricular dysfunction. For years after arrhythmogenic right ventricular cardiomyopathy (ARVC) was first described, the left ventricle (LV) was generally considered normal or minimally involved. In recent years, however, LV involvement has been recognized. It usually presents with early-on arrhythmias more than heart failure symptoms compared to dilated cardiomyopathy. It can be right ventricular, biventricular, or left ventricular. The underlying pathophysiology involves either desmosomal or non-desmosomal mutations. Phospholamban (PLN) mutation is one of those and is associated with more severe arrhythmias and SCD. Primary prevention with ICD implantation should be considered in these patients, even the ones with an ejection fraction greater than 35%. In addition, if such patients progress to Stage D heart failure, they need to be evaluated for advanced heart failure therapies.

Heart Failure Associated With Mycoplasma Pneumoniae Infection, A Case and Review of Literature.

Mycoplasma pneumoniae is well known to cause pulmonary infection. However, it often has extrapulmonary manifestations as well. We diagnosed and treated a 41-year-old female who presented with symptoms of pneumonia along with multisystem involvement, including rash, acute hepatitis, and new onset heart failure that improved with steroids and doxycycline. Subsequent guideline-directed medical therapy for non-ischemic cardiomyopathy (NICM) coincided with the complete recovery of the left ventricular function in three months. We also did a brief literature review with similar prior reported cases.

Influence of nurses' perception of organizational climate and toxic leadership behaviors on intent to stay: A descriptive comparative study.

Background: Nursing managers and leaders must fight to retain nurses in hospitals by constructing an inviting organizational climate that is attractive to work in, not toxic. The organizational climate is primarily affected by employees' internal work environment and behavior. Hence, nursing managers and leaders must implement effective strategies to increase nurses intention to stay by address the organizational climate. Aim: This study was designed to assess nurses' perception of the effects of organizational climate and toxic leadership behaviors on their intention to stay and the differences in these domains between the two hospitals studied. Methods: A descriptive comparative design was used. Data were collected in 2022 from 250 nurses working in the two largest hospitals in Assiut, an Egyptian city south of Cairo, using three self-administered questionnaires: the organizational climate questionnaire (42 items categorized into nine domains), the toxic leadership scale (30 items categorized into five domains), and the Chinese version of the intent-to-stay scale. Results: Most nurses reported their intention to stay as "normal." The nurse participants perceived that a positive organizational climate was not present, but toxic leadership was at a low level (13.6% and 25.6%, respectively). The model of regression analysis was significant, showing that the organizational climate represented by supportive systems impacted nurses' intention to stay in the hospitals under study. Meanwhile, toxic leadership behaviors, represented by authoritarian leadership, unpredictability in the university hospital, and self-promotion in the insurance hospital, affected nurses' intention to stay. Conclusion: Positive organizational climate played a significant role in retaining nurses through investing in incentives and providing supportive systems. Authoritarian leadership, unpredictability, and the self-promotion of leaders' behaviors impacted the nurses and the climate negatively. Hence, we recommend investing in potential strategies to improve the nurses' intention to stay through performance standards, increased pay and benefits, clear reward mechanisms, participation in decision making, and assessments of leaders' behaviors. Furthermore, decision and policy makers need to establish effective, supportive systems in hospitals to retain nurses. Hence, nursing managers and leaders must rethink how they can use their leadership skills and behavior in a positive manner to promote nurse retention. Study registration: Not registered.

Mechanisms of modified LDL-induced pericyte loss and retinal injury in diabetic retinopathy.

AIMS/HYPOTHESIS: In previous studies we have shown that extravasated, modified LDL is associated with pericyte loss, an early feature of diabetic retinopathy (DR). Here we sought to determine detailed mechanisms of this LDL-induced pericyte loss. METHODS: Human retinal capillary pericytes (HRCP) were exposed to 'highly-oxidised glycated' LDL (HOG-LDL) (a model of extravasated and modified LDL) and to 4-hydroxynonenal or 7-ketocholesterol (components of oxidised LDL), or to native LDL for 1 to 24 h with or without 1 h of pretreatment with inhibitors of the following: (1) the scavenger receptor (polyinosinic acid); (2) oxidative stress (N-acetyl cysteine); (3) endoplasmic reticulum (ER) stress (4-phenyl butyric acid); and (4) mitochondrial dysfunction (cyclosporin A). Oxidative stress, ER stress, mitochondrial dysfunction, apoptosis and autophagy were assessed using techniques including western blotting, immunofluorescence, RT-PCR, flow cytometry and TUNEL assay. To assess the relevance of the results in vivo, immunohistochemistry was used to detect the ER stress chaperon, 78 kDa glucose-regulated protein, and the ER sensor, activating transcription factor 6, in retinas from a mouse model of DR that mimics exposure of the retina to elevated glucose and elevated LDL levels, and in retinas from human participants with and without diabetes and DR. RESULTS: Compared with native LDL, HOG-LDL activated oxidative and ER stress in HRCP, resulting in mitochondrial dysfunction, apoptosis and autophagy. In a mouse model of diabetes and hyperlipidaemia (vs mouse models of either condition alone), retinal ER stress was enhanced. ER stress was also enhanced in diabetic human retina and correlated with the severity of DR. CONCLUSIONS/INTERPRETATION: Cell culture, animal, and human data suggest that oxidative stress and ER stress are induced by modified LDL, and are implicated in pericyte loss in DR.

Reduced soluble receptor for advanced glycation end-products (sRAGE) scavenger capacity precedes pre-eclampsia in Type 1 diabetes.

OBJECTIVE: Increased advanced glycation end-products (AGEs) and their soluble receptors (sRAGE) have been implicated in the pathogenesis of pre-eclampsia (PE). However, this association has not been elucidated in pregnancies complicated by diabetes. We aimed to investigate the serum levels of these factors in pregnant women with Type 1 diabetes mellitus (T1DM), a condition associated with a four-fold increase in PE. DESIGN: Prospective study in women with T1DM at 12.2 ± 1.9, 21.6 ± 1.5 and 31.5 ± 1.7 weeks of gestation [mean ± standard deviation (SD); no overlap] before PE onset. SETTING: Antenatal clinics. POPULATION: Pregnant women with T1DM (n = 118; 26 developed PE) and healthy nondiabetic pregnant controls (n = 21). METHODS: Maternal serum levels of sRAGE (total circulating pool), N(ε)-(carboxymethyl)lysine (CML), hydroimidazolone (methylglyoxal-modified proteins) and total AGEs were measured by immunoassays. MAIN OUTCOME MEASURES: Serum sRAGE and AGEs in pregnant women with T1DM who subsequently developed PE (DM PE+) versus those who remained normotensive (DM PE-). RESULTS: In DM PE+ versus DM PE-, sRAGE was significantly lower in the first and second trimesters, prior to the clinical manifestation of PE (P < 0.05). Further, reflecting the net sRAGE scavenger capacity, sRAGE:hydroimidazolone was significantly lower in the second trimester (P < 0.05) and sRAGE:AGE and sRAGE:CML tended to be lower in the first trimester (P < 0.1) in women with T1DM who subsequently developed PE versus those who did not. These conclusions persisted after adjusting for prandial status, glycated haemoglobin (HbA1c), duration of diabetes, parity and mean arterial pressure as covariates. CONCLUSIONS: In the early stages of pregnancy, lower circulating sRAGE levels, and the ratio of sRAGE to AGEs, may be associated with the subsequent development of PE in women with T1DM.

Application of Interactive Video Games as Rehabilitation Tools to Improve Postural Control and Risk of Falls in Prefrail Older Adults.

The purpose of this study was to examine whether interactive video game (IVG) training is an effective way to improve postural control outcomes and decrease the risk of falls. A convenience sample of 12 prefrail older adults were recruited and divided into two groups: intervention group performed IVG training for 40 minutes, twice per week, for a total of 16 sessions. The control group received no intervention and continued their usual activity. Outcome measures were centre of pressure (COP), mean velocity, sway area, and sway path. Secondary outcomes were Berg Balance Scale, Timed Up and Go (TUG), Falls Efficacy Scale International (FES-I), and Activities-Specific Balance Confidence (ABC). Assessment was conducted with preintervention (week zero) and postintervention (week eight). The intervention group showed significant improvement in mean velocity, sway area, Berg Balance Scale, and TUG (p < 0.01) compared to the control group. However, no significant improvement was observed for sway path (p = 0.35), FES-I (p = 0.383), and ABC (p = 0.283). This study showed that IVG training led to significant improvements in postural control but not for risk of falls.
