ABSTRACT

BACKGROUND: The aim was to explore the correlations of leukotriene B4 (LTB4) and 25-hydroxyvitamin D3 [25(OH)D3] levels with disease severity in children with Henoch-Schonlein purpura (HSP).

METHODS: A total of 260 HSP children admitted from January 2017 to December 2018 were selected, and 60 healthy children physically examined in the same period were enrolled as controls. The results of general laboratory tests and expression levels of leukotriene B4 (LTB4) and 25-hydroxyvitamin D3 [25(OH)D3] were compared. The correlations of LTB4 and 25(OH)D3 with immunoglobulin A (IgA) were statistically analyzed, and the expression levels of LTB4 and 25(OH)D3 were compared between Henoch-Schonlein purpura nephritis (HSPN) group and non-Henoch-Schonlein purpura nephritis (NHSPN) group. The optimal cutoff values of LTB4 and 25(OH)D3 to predict HSP were analyzed by receiver operating characteristic (ROC) curves, based on which they were divided into low-, intermediate-, and high-risk groups. The length of hospital stay and recurrence rate within 6 months were compared.

RESULTS: The levels of white blood cell count, platelets, C-reactive protein, IgA, IgM, IgE, complement C3, and LTB4 were significantly higher and 25(OH)D3 was lower in HSP group than those in control group (p < 0.05). IgA, LTB4, and 25(OH)D3 levels were independent risk factors for HSP (p < 0.05). LTB4 was positively correlated with IgA (p < 0.05), and 25(OH)D3 was negatively correlated with IgA (p < 0.05). LTB4 level was significantly higher and 25(OH)D3 level was lower in HSPN group than those in NHSPN group (p < 0.05). The optimal cutoff values of LTB4 and 25(OH)D3 were 27.82 pg/mL and 22.10 ng/mL, respectively, the length of hospital stay gradually increased in low-, intermediate-, and high-risk groups, and the recurrence rates within 6 months were 14.2%, 31.5%, and 39.6%, respectively (p < 0.05).

CONCLUSIONS: LTB4 level increases and 25(OH)D3 level decreases in children with HSP, and the expression levels are significantly correlated with disease severity, suggesting predictive values for prognosis.

ABSTRACT

BACKGROUND: According to recent studies, thrombotic complications frequently occur in Coronavirus Disease-19 (COVID-19) and are associated with increasing disease severity and poor prognosis. However, conventional coagulation assays are unable to identify these patients’ hypercoagulable states, raising questions about the appropriate assessment tool. We aimed to evaluate coagulation abnormalities in patients with different severity of CO-VID-19 using viscoelastic tests.

METHODS: This was a single center retrospective observational study in a group of 50 adult patients with SARS-COV-2 infection and different severity of pneumonia (20 moderate, 30 severe). Coagulation status was evaluated using rotational thromboelastometry (ROTEM®) in conjunction with conventional coagulation assays (platelet count, PT, aPTT, fibrinogen, and D-dimer levels).

RESULTS: Shorter than normal EXTEM CFT, higher than normal A10 and MCF in INTEM, EXTEM, and FIBTEM and higher than normal α-angle were classified as markers of hypercoagulable state. Forty-four (88%) patients had at least two hypercoagulable ROTEM parameters. Seven patients developed thromboembolic complications. All were classified as having severe COVID-19 pneumonia. With increment increases in disease severity, we observed an increase in the number of patients with hypercoagulable parameters and higher INTEM, EXTEM, and FIBTEM MCF but without being statistically significant. On the other hand, we noted a significant decrement of PT (p = 0.039), higher fibrinogen (p = 0.001), higher D dimer (p < 0.001), and shorter CT EXTEM (p < 0.001).

CONCLUSIONS: Our findings support the presence of a hypercoagulable state in COVID-19 patients, especially in the severe forms. It also highlights the role of viscoelastic tests in assessing COVID-19 coagulopathy and, therefore, their potential use in thrombophrophylactic management.

ABSTRACT

BACKGROUND: Along with vitamin D deficiency, a common global health problem in developed and developing countries, zinc deficiency also remains one of the most common micronutrient deficiencies-related public health problems in some parts of the world. Determination of vitamin D and Zn status is important for the growth, development, and health of school-age children, as well as their intellectual achievement and academic performance. In this study, we aimed to evaluate serum 25(OH)D and Zn levels and the relationship between them in a nationally representative sample of Turkish children and adolescents.

METHODS: A total of 541 children and adolescents aged 1 – 16 years were included in our study whose vitamin D and zinc test levels were measured and who applied to the Basaksehir Cam and Sakura City Hospital Pediatric Outpatient Clinic. Cases were examined by dividing them into subgroups according to their vitamin D levels (≤ 15 ng/mL deficiency; 15 – 20 ng/mL insufficiency; ≥ 20 ng/mL sufficiency) and age (< 5 years preschool; 5 – 10 years middle childhood; 11 – 16 years adolescence).

RESULTS: The levels of 25(OH)D were lower than 20 ng/mL in 33% of the children. There was deficiency in 80 (15%) and insufficiency in 99 (18%) cases. A statistically significant difference was found in 25(OH)D and Zn levels in groups separated by 25(OH)D level and age (p < 0.001). A positive significant correlation was found between serum 25(OH)D and Zn levels (r = 0.468; p < 0.001). A negative correlation was found between 25(OH) D levels and age (r = -0.261; p < 0.001) and body mass index (BMI) (r = -0.308; p < 0.001).

CONCLUSIONS: In our study, we found high levels of vitamin D deficiency and insufficiency and a significant positive correlation between serum 25(OH)D and Zn levels in the pediatric population. Based on this possible contribution, we think that providing vitamin D support to children of all ages, including adolescents, and thus improving zinc levels may be beneficial in protecting from diseases that lead to morbidity and mortality as a result of reducing the rate of growth and development retardation, regulating of bone development, and contributing to the development of the immune system.

ABSTRACT

BACKGROUND: Patients with peritoneal dialysis commonly have severe disorders of lipid metabolism, with particularly severe changes in serum lipoprotein(α) [Lp(α)]. Serum Lp(α) may play a role in the risk of mortality in peritoneal dialysis patients. The aim was to investigate the correlation between high serum Lp(α) levels and all-cause mortality and death from cardiovascular events and infection in peritoneal dialysis patients.

METHODS: Three hundred and ninety-two patients with end-stage kidney disease who started peritoneal dialysis treatment between March 1, 2007 and May 31, 2020, were selected. Clinical data of all enrolled patients after 3 months of peritoneal dialysis were collected. Based on the median value of serum Lp(α) level, all enrolled patients were divided equally into a high serum Lp(α) level group (> 275.95 mg/L, n = 196) and a low serum Lp(α) level group (< 275.95 mg/L, n = 196). SPSS25.0 statistical software was used to analyze the factors affecting serum Lp(α) levels and the correlation between high serum Lp(α) levels and all-cause mortality and death from cardiovascular events and infection in peritoneal dialysis patients.

RESULTS: Binary multivariate logistic regression analysis showed that higher low-density lipoprotein (LDL) levels (OR = 1.614, 95% CI: 1.261 – 2.068, p = 0.000) and high Body Mass Index (BMI) levels (OR = 1.063, 95% CI: 1.004 – 1.126, p = 0.036) were the risk factors for the high serum Lp(α) levels. High serum albumin levels (OR = 0.959, 95% CI: 0.927 – 0.991, p = 0.014) and high parathyroid hormone levels (OR = 0.999, 95% CI: 0.997 – 1.000, p = 0.010) were protective factors for the high serum Lp(α) levels. The cumulative survival of patients in the high serum Lp(α) level group was lower in death from cardiovascular events as shown by Kaplan-Meier survival analysis (Log-rank test χ2 = 4.348, p = 0.037). Multivariate Cox regression analysis showed that high serum Lp(α) levels were an independent risk factor for death from cardiovascular events in peritoneal dialysis patients (HR = 1.002, 95% CI: 1.001 – 1.003, p = 0.001).

CONCLUSIONS: The occurrence of high serum Lp(α) levels in peritoneal dialysis patients was positively associated with LDL and BMI, and negatively associated with serum albumin and parathyroid hormone levels. High serum Lp(α) levels were related to the risk of death from cardiovascular events in peritoneal dialysis patients.

ABSTRACT

As the SARS-CoV-2 virus spreads around the world new variants are appearing regularly. Although some countries have achieved very swift and successful vaccination campaigns, on a global scale the vast majority of the population is unvaccinated and new variants are proving more resistant to the current set of vaccines. We present a simple model of disease spread, which includes the evolution of new variants of a novel virus and varying vaccine effectiveness to these new strains. We show that rapid vaccine updates to target new strains are more effective than slow updates and containing spread through non-pharmaceutical interventions is vital while these vaccines are delivered. Finally, when measuring the key model inputs, e.g. the rate at which new mutations and variants of concern emerge, is difficult we show how an observable model output, the number of new variants that have been seen, is strongly correlated with the probability the virus is eliminated.

ABSTRACT

AIMS AND BACKGROUND: Shoulder pathologies are frequently linked to sleep disturbances. The aim of this study is to investigate the effect on sleep disorders in patients with arthroscopic rotator cuff repair.

MATERIALS AND METHODS: Thirty-three patients who underwent arthroscopic rotator cuff repair due to a full-thickness rotator cuff tear were prospectively analyzed. The Pittsburgh Sleep Quality Index (PSQI), the American Shoulder and Elbow Surgeons Shoulder Score (ASES), visual analog scale (VAS), and Constant and Murley shoulder scores before surgery and at 6 months postoperatively. Preoperative clinical and radiological parameters of the patients were also evaluated.

RESULTS: The study analyzed 33 patients with a median age of 59.79 ± 9.0 years. There was a significant difference preoperatively versus postoperatively in terms of all PSQI global scores and subdivisions (P < 0.001). A statistically significant improvement was determined by the simple shoulder test, the Constant and Murley shoulder scores, and VAS (P < 0.001).

CONCLUSION: Sleep disturbance is common in patients with symptomatic rotator cuff tear, and sleep disturbance can resolve after arthroscopic rotator cuff repair.

ABSTRACT

BACKGROUND: Psoriatic arthritis can cause pain, disability, and permanent joint damage. This can lead to impairments in work and social participation. Little is known about the extent of these impairments in routine practice. With this study, we aim to examine the extent of work and activity impairment in (subgroups of) Dutch patients with psoriatic arthritis (PsA), and to examine determinants associated with this impairment.

METHODS: This is an observational study using data collected from the electronic health records of PsA patients treated at the Sint Maartenskliniek, the Netherlands. Data about work and activity impairment were collected via the Work Productivity and Activity Impairment questionnaire. To compare our PsA-cohort with the Dutch general population, we used age- and sex-matched data derived from the Central Bureau of Statistics. Regression analyses were performed to examine determinants of work and activity impairment.

RESULTS: In total, 246 patients were included, of which 126 (51.2%) were female. Mean age (S.D.) was 55.7 (13.2) years. Compared with the Dutch general population, work for pay (WFP) was significantly lower in PsA (52.9% versus 62.6%, P < 0.001). In PsA, younger age and better physical function were associated with WFP status (P < 0.05). Higher disease activity, worse physical function, and worse mental health-related quality of life were associated with both more work and activity impairment (P < 0.05). Furthermore, reaching low disease activity status (LDA) according to Psoriatic ArthritiS Disease Activity Score (PASDAS; ≤ 3.2) was associated with less work and activity impairment than reaching LDA according to DAS28-CRP (≤ 2.9) (P < 0.05).

CONCLUSIONS: In PsA patients, worse physical function was associated with a lower likelihood of having WFP, and higher work and activity impairment. PASDAS LDA as a goal for treat to target, compared to DAS28-CRP, appears to favour the reduction of work and activity impairment.

ABSTRACT

BACKGROUND: Surveillance efforts are essential to pandemic control, especially where the state is the primary health provider, such as Brazil. When public health testing guidelines limit molecular tests, there are reductions in detection efforts aimed at early recognition, isolation, and treatment of those infected with the virus. This study evaluates the effectiveness of surveillance policies to control the COVID-19 pandemic in São Paulo.

METHODS: We conducted an interrupted time series analysis with a segmented regression model to analyze if changes in the state’s guidelines improved RT-PCR testing outcomes in Brazil’s most affluent and largest state, São Paulo. Anonymized daily data on the RT-PCR tests conducted in public laboratories belonging to the state-wide network from March 1, 2020 to June 5, 2021 were extracted from the Sao Paulo State open-source database, while the data on the genomic sequences were obtained from GISAID. We then aggregated these data for the 17 regional health departments in the state to evaluate regional-level outcomes.

RESULTS: The public health system restricted RT-PCR testing to hospitalized cases in the first months. Testing was expanded to permit symptomatic testing of non-hospitalized persons only in July 2020, but a statistically significant increase in surveillance efforts was not observed. Case definition was expanded to allow case confirmation based on clinical, laboratory and image data criteria other than an RT-PCR test without increasing the testing effort for asymptomatic suspicious cases in September 2020. There was an increase in the mean volume of testing in each RHD, but the test positivity rate increased due to insufficient testing expansion. Results also show an uneven improvement in testing outcomes following these changes across the state’s regional health departments.

CONCLUSIONS: Evidence suggests that lower RT-PCR testing and genomic surveillance efforts are associated with areas characterized by a higher population concentration and a greater population reliance on the public health system. Our results highlight the need to structure health surveillance and information systems for disease control and prevention in emergency settings considering local demographics and vulnerabilities. In high prevalence settings, efforts at identifying and including vulnerable populations in routine and enhanced surveillance programs during COVID-19 must be significantly improved.

ABSTRACT

BACKGROUND: The vector species in the Amazon River Basin are regionally and locally diverse, which makes it imperative to understand and compare their roles in malaria transmission to help select appropriate methods of intervention and evaluation. The major aim of this study was to measure the vectorial capacity of five Anopheles species in three neighbouring villages, for two Plasmodium parasite species affecting humans.

METHODS: From 32 consecutive months of sampling in three villages, 1.5-7.0 km apart, on the Matapi River, Amapá State, Brazil, vectorial capacities (C) were estimated as time series for An. darlingi, An. marajoara, An. nuneztovari, An. triannulatus, and An. intermedius. Monthly parity measurements for each vector species were used to estimate daily survivorship and compared to estimates of survivorship from mark-release-recapture experiments. Gonotrophic cycle lengths were estimated through a time-series analysis of parity data, and durations of sporogony at study site temperatures for the two malaria parasite species were estimated from previous literature.

RESULTS: The absolute abundances of five vector species were strongly tracked by the spatial variation in C among villages. Temporally, C varied between wet and dry seasons, with An. darlingi, An. marajoara and An. triannulatus exhibiting higher C in the dry season from August to December, and An. nuneztovari its highest C early in the rainy season in January and February. Anopheles intermedius exhibited higher C in the rainy season from April to June than in the dry season. Significant differences in overall survival for each independent variable, and a significant difference in C between wet and dry seasons, among villages, and among vector species for both Plasmodium falciparum and Plasmodium vivax. A generalized linear mixed model (GLMM) analysis by village showed significant effects of vector species on C in only one village, but significant effects of parasite species in all three. Although the GLMM analysis detected no significant parasite x vector species interaction effects on C, effects on C of spline regressions of C dynamics x vector species interactions were significant in all villages.

CONCLUSIONS: These detailed analyses of entomological and parasitological variables revealed hidden complexities of malaria epidemiology at local scales in neighbouring riverine villages of the Amazon Region.

ABSTRACT

BACKGROUND AND AIM: The chronic, progressive nature of multiple sclerosis (MS) demands long-term family-centered care for patients. In view of that, inadequate education and support provided for the family caregivers (FCGs) of MS patients increase their care burden (CB) and affect their lifestyle. This study aimed to investigate the impact of a healthy lifestyle empowerment program (HLEP) on CB and adherence to health-promoting behaviors (HPBs) in the FCGs of patients suffering from MS.

METHODS: In this experimental study with parallel groups, conducted in Iran in 2020, a total of 60 FCGs of MS patients were recruited, and then randomized into intervention (n = 30) or control (n = 30) groups. The intervention program, the HLEP, was thus implemented virtually via WhatsApp in the intervention group upon coordinating with the MS Association in the city of Yasuj, Iran, and selecting the participants. The data were collected at three stages, including baseline, follow-up 1 (immediately after the HLEP), and follow-up 2 (three months after HLEP). The research tools were a 14-item demographic survey questionnaire, the 24-item Caregiver Burden Inventory, and the 52-item Health-Promoting Lifestyle Profile-II. Independent-samples t-test, repeated measures analysis of variance, and a linear mixed model were further used for statistical analyses, considering the significant level of 0.05.

RESULTS: The study results revealed a significant decrease in the CB scores from the baseline to the follow-up 2 (77.03 ± 15.76 to 42.33 ± 12.37), and a significant increase in the values of adherence to HPBs from the baseline to the follow-up 2 (123.53 ± 14.01 to 148.06 ± 15.04) were obtained in the intervention group (p < 0.001). The linear mixed model also showed that the significant absolute changes in the scores of CB and adherence to HPBs during the follow-ups in the intervention group, compared to those in the controls, were – 8.92 and 16.47 units, respectively (p < 0.001).

CONCLUSION: Health care managers, planners, and providers are highly recommended to start developing and implementing various HLEPs for reducing CB and improving adherence to HPBs among the FCGs of patients with MS.
