Modeling and empirical verification of dependences of the influence of socio-economic situation of elderly persons on the level of resilience.

Adv Gerontol. 2021;34(6):953-960.

ABSTRACT

The work carried out an empirical analysis of the impact on the level of vitality of the parameters of the socio-economic situation of elderly people based on the data of a sociological survey. The modeling of the study of the influence included the choice of variables taking into account the criterion of the complexity of the measured parameters. The empirical basis for the study was the results of a survey (n=400) of elderly people living in cities and rural areas of the Tomsk region. Modeling and correlation analysis are used to test hypotheses. To identify the dependence, a formal model of the relationship of resilience with the selected parameters of the socio-economic situation is used as a system of indicators, to which the methods of mathematical statistics are applied to identify their impact on strengthening the resilience of older people. The results of the study confirm the influence of satisfaction with material prosperity on the resilience of elderly people. Correlations of resilience with different parameters, including gender, place of residence and higher education, were revealed.

Chronic spontaneous urticaria treated with bloodletting therapy and auricular point sticking on the base of xuanfu theory: a randomized controlled trial

Zhongguo Zhen Jiu. 2022 Feb 12;42(2):157-61. doi: 10.13703/j.0255-2930.20210719-0005.

ABSTRACT

OBJECTIVE: To compare the clinical therapeutic effect and the impacts on recurrence rate on chronic spontaneous urticaria (CSU) between the combined treatment of bloodletting therapy and auricular point sticking on the base of xuanfu theory and the oral solution of levocetirizine hydrochloride.

METHODS: A total of 86 patients with CSU were randomized into an observation group (43 cases, 1 case dropped off) and a control group (43 cases, 3 cases dropped off). In the observation group, bloodletting therapy at Dazhui (GV 14), Feishu (BL 13), Geshu (BL 17) and Pishu (BL 20) was combined with auricular point sticking at lung (CO14), kidney (CO10), shenmen (TF4) and heart (CO15), etc. This combined treatment was given once every two days. In the control group, the oral solution of levocetirizine hydrochloride was prescribed, 10 mL each time, once daily. The treatment lasted for 4 weeks in the two groups. Before and after treatment, urticaria activity score 7 (UAS7), the score of dermatology life quality index (DLQI) and the levels of serum immune globulin E (IgE), interleukin 4 (IL-4) and interferon γ (IFN-γ) were compared in the patients between the two groups. The clinical therapeutic effect was evaluated in patients of the two groups and the recurrence rate was followed up 4, 8 and 12 weeks after treatment separately.

RESULTS: After treatment, the scores of UAS7 and DLQI, as well as the levels of serum IgE and IL-4 were all reduced as compared with those before treatment in the two groups (P<0.05), and the level of serum IFN-γ was increased (P<0.05). The total effective rate was 83.3% (35/42) in the observation group and was 85.0% (34/40) in the control group. There was no statistical significance for the difference in the clinical therapeutic effect between the two groups (P>0.05). Eight and 12 weeks after treatment, the recurrence rates were 21.1% (4/19) and 26.3% (5/19) in the observation group, lower than 55.0% (11/20) and 65.0% (13/20) in the control group, respectively (P<0.05).

CONCLUSION: The combined therapy of bloodletting and auricular point sticking on the base of xuanfu theory relieves the clinical symptoms, regulates the levels of serum IgE, IL-4 and IFN-γ and improves the quality of life in the patients with CSU. The clinical therapeutic effect of this combined treatment is similar to the oral solution of levocetirizine hydrochloride. But, the recurrence rate of the combined treatment of bloodletting and auricular point sticking is lower and its long-term curative effect is better.

Assessing the impact of pandemic on the resilience of older adults in Tomsk region.

Adv Gerontol. 2021;34(6):928-933.

ABSTRACT

The article presents pioneer results of assessing the impact of the pandemic on the resilience of the older adults of the Tomsk region. We assessed the resilience of older adults and its predictors basing upon the survey of 400 respondents aged 55-92 using the Connor-Davidson resilience scale (CD-RISC-25). The results reveal statistically significant relationship between the resilience, material well-being and emotional state of elderly respondents in the context of the coronavirus pandemic. The results of the study complement the existing approaches to assessing and measuring the parameters of the quality of life of the older adults, and can be used to design tools for strengthening the resilience in line with the concept of active ageing.

Human urinary kallidinogenase may improve the prognosis of acute stroke patients with early neurological deterioration

Brain Behav. 2022 Feb 13:e2524. doi: 10.1002/brb3.2524. Online ahead of print.

ABSTRACT

OBJECTIVES: Some acute ischemic stroke (AIS) patients still suffer from early neurological deterioration (END) after receiving intravenous thrombolysis (IVT), and these patients often have a poor prognosis. The purpose of our study is to observe the efficacy and safety of human urinary kallidinogenase (HUK) treatment in patients with END.

METHODS: This was a retrospective analysis and 49 patients with END who met the inclusion criteria were divided into the observation group and the control group. All patients received routine treatment of AIS, while patients in the observation group were treated with HUK within 24 h after IVT and the other group without HUK.

RESULTS: There were 24 patients in the observation group and 25 patients in the control group. After treatment, favorable prognosis (mRS scores ≤2) at 3 months in the observation group with 13 cases (54.17%) was significantly better than that in the control group with four cases (16%) (p = .001), and there was no statistical difference between the two groups in any hemorrhagic complication.

CONCLUSION: HUK is considered to be safe and may improve the prognosis of AIS patients with END after IVT. More clinical trials are needed to validate these results in the future.

Intralesional Vitamin D3 in Treatment of Alopecia Areata: A randomized-controlled clinical trial

J Cosmet Dermatol. 2022 Feb 13. doi: 10.1111/jocd.14844. Online ahead of print.

ABSTRACT

BACKGROUND: Alopecia areata (AA) is a common non-scarring, inflammatory type of hair loss that affects people of all ages and genders.

AIMS: To evaluate the safety and efficacy of Intralesional vitamin D3 injection in the treatment of alopecia areata.

PATIENTS AND METHODS: A randomized- control clinical trial included a total of 60 adult patients with localized alopecia areata were randomly assigned into two groups . Group I consisted of thirty patients who received 1ml of intralesional injection of vitamin D3 every 4 weeks for a maximum of 3 sessions. Group II consisted of thirty patients who received intralesional injection of normal saline 0.9% every 4 weeks for 3 sessions as a control group. All patients had their serum levels of 25-hydroxy vitamin D, TSH, antithyroglobulin, and thyroid peroxidase antibodies estimated before starting treatment. The 5-point semiquantitative regrowth score (RGS) and dermoscopy were used to evaluate the therapeutic response.

RESULTS: There was statistically significant difference with p-value < 0.001 between two study groups regarding to degree of improvement. Dermoscopic findings that explain signs of activity were decreased, and signs of improvement were appeared after the 3rd months of treatment being better in intralesional vitamin D group.The adverse effects were negligible and transient, and there were no recurrence of lesions.

CONCLUSION: Intralesional vitamin D3 is an effective treatment option for localized patchy (not more than 40% of scalp distribution) alopecia areata .There is no relation between serum vitamin D3 and efficacy of treatment, so measuring vitamin D3 before starting treatment is not advised.

Longitudinal impact of trauma in the North American Prodrome Longitudinal Study-3

Early Interv Psychiatry. 2022 Feb 13. doi: 10.1111/eip.13270. Online ahead of print.

ABSTRACT

AIM: Individuals at clinical high risk (CHR) for psychosis have been shown to experience more trauma than the general population. However, although the effects of trauma appear to impact some symptoms it does not seem to increase the risk of transition to psychosis. The aim of this article was to examine the prevalence of trauma, and its association with longitudinal clinical and functional outcomes in a large sample of CHR individuals.

METHODS: From the North American Prodrome Longitudinal Study-3 (NAPLS-3) 690 CHR individuals and 91 healthy controls from nine study sites between 2015 and 2018 were assessed. Historical trauma experiences were captured at baseline. Participants completed longitudinal assessments measuring clinical outcomes including positive and negative symptoms, depression, social and role functioning and assessing transition to psychosis.

RESULTS: From the 690 CHR participants and 96 healthy controls, 343 (49.6%) and 15 (15.6%), respectively, reported a history of trauma (p < .001). Emotional neglect (70.3%) was the most commonly reported type of trauma, followed by psychological abuse (57.4%). Among CHR participants, time to transition to psychosis was not associated with trauma. Baseline depression and suspiciousness/persecutory ideas were statistically significantly different between CHR individuals who did or did not experience trauma. However, when examining clinical and functional outcomes over 12-months of follow-up, there were no differences between those who experienced trauma and those who did not.

CONCLUSION: Overall, trauma is a significantly prevalent among CHR individuals. The effects of trauma on transition and longitudinal clinical and functional outcomes were not significant.

Towards improved modeling of SOC decomposition: soil water potential beyond the wilting point

Glob Chang Biol. 2022 Feb 13. doi: 10.1111/gcb.16127. Online ahead of print.

ABSTRACT

Soils are important carbon (C) reservoirs and play a critical role in regulating the global C cycle. Soil water potential (SWP) measures the energy with which water is retained in the soil and is one of the most vital factors that constrain the decomposition of soil organic C (SOC). The measurements for soil water retention curve (SWRC), on which the estimation of SWP depends, are usually carried out above -1.5 MPa (i.e., the wilting point for many plants). However, the average moisture threshold at which soil microbial activity ceases is usually below -10 MPa in mineral soils. Beyond the measurement range, the SWP estimation has to be derived from extrapolating the SWRC, which violates the statistical principle, resulting in possibly inaccurate SWP estimations. To date, it is unclear to what extent the extrapolated SWP estimation deviates from the “true value” and how it impacts the modeling of SOC decomposition. This study combined SWRC measurements down to -43.7 MPa, a 72-day soil incubation experiment with four moisture levels, and a SOC decomposition model. In addition to the complete SWRC (SWRCall ), we fitted two more SWRCs by using measurements above -0.5 MPa (SWRC0.5 ) and -1.7 MPa (SWRC1.7 ), respectively, to quantify the deviations of extrapolated SWPs from the complete SWRC. Results showed that extrapolating the SWRC beyond its measurement range significantly underestimated the SWP. Incorporating the extrapolated SWP in the model significantly underestimated the SOC decomposition under relatively dry conditions. With the extrapolated SWP, the model predicted no SOC decomposition in the driest treatment, while the experiment observed a significant CO2 emission. The results emphasize that accurate SWP estimations beyond the wilting point are critically needed to improve the modeling of SOC decomposition.

DNA extracellular traps as potential biomarker of chronic haemophilic synovitis and therapeutic perspective in patients treated with PRP: A pilot study

Haemophilia. 2022 Feb 13. doi: 10.1111/hae.14508. Online ahead of print.

ABSTRACT

INTRODUCTION: Hemarthrosis causes chronic haemophilic synovitis (CHS). Although neutrophils are major immune cells infiltrating joints after bleeding, their role on the pathogenesis of CHS is unknown. Neutrophils release extracellular DNA traps (ETs), structures of DNA with bound granular enzymes that were associated with tissue damage.

AIMS: To evaluate the presence of ETs as pathogenic biomarker and the protective effect of intraarticular injection of platelet-rich plasma (PRP) in patients with CHS.

METHODS: Haemophilia Joint Health Score (HJHS) and bleeding episodes (BE) were measured and correlated with ETs indicators (DNA/DNA-Elastase) in synovial fluids (SF), PRP and plasma of 21 patients.

RESULTS: Soluble DNA and DNA-Elastase were detected in SF and plasma of patients. The synovial and plasma levels of DNA-Elastase positively correlated with worse HJHS/BE. Interestingly, remaining ETs-inducer factors were present in SF that induced the in vitro release of ETs from blood-isolated neutrophils. This phenomenon was impaired by adding plasma or PRP. Finally, preliminary data obtained from five patients indicate that levels of DNA-Elastase and HJHS/BE decreased after receiving intraarticular injection of PRP.

CONCLUSIONS: The synovial and plasma levels of DNA-Elastase correlated with worse HJHS/BE suggesting that ETs formation could be a biomarker and potential therapeutic target for CHS. The intraarticular injection of PRP underlined a new potential alternative therapy, decreasing ETs formation in synovia of patients with CHS. However, our hypotheses must be confirmed in the future with better designed and more statistical power studies. Meanwhile, the use of intraarticular injections of PRP for the treatment of CHS remains controversial.

Long-term renal safety between patients with chronic hepatitis B receiving tenofovir vs. entecavir therapy: A multicenter study

J Viral Hepat. 2022 Feb 13. doi: 10.1111/jvh.13656. Online ahead of print.

ABSTRACT

Renal safety is a critical issue in chronic hepatitis B (CHB) patients receiving long-term entecavir (ETV) or tenofovir disofuroxil fumarate (TDF) therapy. We investigated their effects on estimated glomerular filtration rate (eGFR). Treatment-naïve CHB patients receiving ETV or TDF for ≥1 year were recruited. The eGFR was assessed using the Chronic Kidney Disease Epidemiology Collaboration equation. We calculated average annual percent change (AAPC) in eGFR using Joinpoint regression. At the beginning of the observation, the ETV group had more unfavorable conditions than the TDF group: lower eGFR and higher FIB-4 and APRI than the TDF group (all P<0.001). After 6 years of antiviral therapy, the mean eGFR in the ETV group (n=1,793) was maintained (96.0 at first year to 95.6 mL/min/1.73 m2 at sixth year; AAPC -0.09%; P=0.322), whereas that in the TDF group (n=1,240) significantly decreased annually (101.9 at first year to 96.9 mL/min/1.73 m2 at sixth year; AAPC -0.88%; P<0.001). Notably, in the TDF group, even patients without diabetes (AAPC -0.80%; P=0.001) or hypertension (AAPC -0.87%; P=0.001) experienced significant decrease in eGFR. Expectably, accompanying diabetes (AAPC -1.59%; p=0.011) or hypertension (AAPC -1.00%; p=0.002) tended to accelerate eGFR decrease. TDF treatment (odds ratio 1.66, P<0.001), along with eGFR<60 mL/min/1.73 m2 , serum albumin<3.5 mg/dL, and hypertension, were independently associated with ongoing renal dysfunction, defined as a negative slope of the mean eGFR change. In conclusion, compared to ETV, long-term TDF treatment induced slow, but progressive renal dysfunction. Although the annual eGFR change by TDF was small, careful monitoring is necessary, especially in patients requiring life-long therapy.

Assessment of sunlight exposure across industries and occupations using blood vitamin D as a biomarker

J Occup Health. 2022 Jan;64(1):e12318. doi: 10.1002/1348-9585.12318.

ABSTRACT

OBJECTIVE: Exposure to ultraviolet (UV) radiation from sunlight induces the production of essential vitamin D, whereas overexposure to sunlight leads to skin cancer. Sunlight exposure has been measured using questionnaires, dosimeters, and vitamin D levels. Several studies have measured vitamin D in the working population; however, these studies were limited to certain occupations such as farmers and construction workers. In the present study, we evaluated sunlight exposure using blood vitamin D as an exposure surrogate across industries and occupations.

METHODS: The Korea National Health and Nutrition Examination Survey (KNHANES) is a nationwide study representing the Korean population. We analyzed data from KNHANES between 2008 and 2009. We examined the association between vitamin D levels and pertinent personal, seasonal, residential, and occupational factors. Furthermore, we developed a multiple regression model with factors other than occupational factors (industry and occupation) and obtained residual values. We computed the third quartile (Q3) of the residuals and then calculated the fractions exceeding the Q3 level for each combination of industry and occupation.

RESULTS: Age, sex, body mass index, year, season, latitude, living area, living in an apartment, industry, and occupation were significantly associated with vitamin D levels. Based on the exceeding fraction, the armed forces showed the highest exceeding fraction level of 0.71.

CONCLUSIONS: Our results present the high exposure groups to sunlight across industries and occupations. Our results may provide a source for prioritizing occupational groups with a high risk of adverse health effects from sunlight exposure.
