Health and Socioeconomic Determinants of Abuse among Women with Disabilities.

The double vulnerability of women with disabilities places them at the center of this research paper. Intersectionality is key in research on gender-based violence. This study analyzes the perspective of the victims and non-victims themselves on this issue, through a comparative analysis between women with and without disabilities, at two levels of analysis: quantitative, through the adaptation of various scales (Assessment Screen-Disability/AAS-D, and the Woman Abuse Screening Tool/WAST), and qualitative, with semi-structured interviews (open scripts and different themes), and focus groups with experts from the associative network.

A comprehensive review on green perspectives of electrocoagulation integrated with advanced processes for effective pollutants removal from water environment.

The rapidly expanding global energy demand is forcing a release of regulated pollutants into water that is threatening human health. Among various wastewater remediating processes, electrocoagulation (EC) has scored a monumental success over conventional processes because it combines coagulation, sedimentation, floatation and electrochemical oxidation processes that can effectively decimate numerous stubborn pollutants. The EC processes have gained some attention through various academic and industrial publications, however critical evaluation of EC processes, choices of EC processes for various pollutants, process parameters, mechanisms, commercial EC technologies and performance enhancement via other degradation processes (DPs) integration have not been comprehensively covered to date.

Removal of nutrients and other emerging inorganic contaminants from water and wastewater by electrocoagulation process.

The continual discharge of emerging inorganic pollutants into natural aquatic systems and their negative effects on the environment have motivated the researchers to explore and develop clean and efficient water treatment strategies. Electrocoagulation (EC) is a rapid and promising pollutant removal approach that does not require any chemical additives or complicated process management. Therefore, inorganic pollutant treatment via the EC process is considered one of the most feasible processes.

Decadal Change in Seroprevalence of Chikungunya Virus Infection in Pune City, India.

Chikungunya virus (CHIKV) is an arthropod-borne virus capable of causing large outbreaks. We aimed to determine the decadal change in the extent of chikungunya virus infection from 2009 to 2019. We implemented a prospective cross-sectional survey in Pune City using a 30-cluster approach with probability-proportion-to-size (PPS) sampling, with blood samples collected from 1654 participants in early 2019.

Methods: Serum samples of symptomatic cases (n=33) were screened for dengue virus (DENV), CHIKV and Zika virus (ZIKV) by molecular and serological assays.

Results: The first case of ZIKV infection from Maharashtra was detected and confirmed by molecular and serological assays.

Studies on electrode combination for COD removal from domestic wastewater using electrocoagulation.

Electrocoagulation is an electrochemical method that uses sacrificial electrodes to remediate wastewater. The combination of electrodes for the treatment of domestic wastewater is the factor that influences the removal efficiency of COD (Chemical Oxygen Demand) by using the electrocoagulation process. Aluminum and Iron electrodes are combined as anode-cathode and cathode-anode in Al-Al, Fe-Fe, Al-Fe, and Fe-Al.

Wastewater treatment using a natural coagulant ( seeds): optimization through response surface methodology.

The high expense of chemical coagulant-treated water forces most people in rural regions to rely on easily available sources, which are usually of poor quality, and expose them to waterborne infections. According to this statement, the purpose of this study was to confirm the efficiency of extracting powder seeds, which are widely available in rural regions. The experiment was done based on a random design load of 0.

Association of single nucleotide polymorphisms in the CD209, MMP9, TNFA and IFNG genes with susceptibility to Japanese encephalitis in children from North India.

Japanese encephalitis (JE), an acute encephalitis syndrome disease caused by infection with JE virus (JEV), is an important mosquito borne disease in developing countries. The clinical outcomes of JEV infection show inter individual differences. Only in a minor percent of the infected subjects, the disease progresses into acute encephalitis syndrome.

Use of whole blood over plasma enhances the detection of dengue virus RNA: possible utility in dengue vaccine trials.

In the present study, the utility of viral RNA isolated from whole blood over plasma for detection of dengue virus (DENV) was investigated in 80 samples referred for serotyping by DENV serotype-specific one-step real-time RT-PCR. DENV RNA was detected in 71.25% of the whole blood samples compared to 46.

Spatio-temporal distribution analysis of circulating genotypes of dengue virus type 1 in western and southern states of India by a one-step real-time RT-PCR assay.

Dengue virus type 1 (DENV-1) Asian and American/African (AM/AF) genotypes were reported to be co-circulating in southern and western states of India based on envelope (E) gene sequencing of few representative samples. The objective of the present study was to develop a one-step real-time RT-PCR to discriminate between Asian and AM/AF genotypes of DENV-1 and investigate the spatio-temporal distribution of the DENV-1 genotypes in southern and western states of India. A one-step real-time RT-PCR to discriminate the Asian and AM/AF genotypes of DENV-1 was developed and validated using 40 samples (17 Asian and 23 AM/AF), for which the envelope (E) gene sequence data was available.

An exploratory study of the effect of regular aquatic exercise on the function of neutrophils from women with fibromyalgia: role of IL-8 and noradrenaline.

Fibromyalgia (FM) syndrome is associated with elevated systemic inflammatory and stress biomarkers, and an elevated innate cellular response mediated by monocytes and neutrophils. Exercise is accepted as a good non-pharmacological therapy for FM. We have previously found that regular aquatic exercise decreases the release of inflammatory cytokines by monocytes from FM patients.

Altered profile of chemokines in fibromyalgia patients.

Background: Fibromyalgia (FM) is a syndrome characterized by widespread chronic pain. Its aetiology is still poorly understood, and there are no haematochemical or instrumental tests on which to base a diagnosis. Recent studies suggest that its pathogenesis may involve cytokines, in particular, chemokines - cytokines that regulate cell traffic under both physiological and pathological conditions.

Fibromyalgia: anti-inflammatory and stress responses after acute moderate exercise.

Fibromyalgia (FM) is characterized in part by an elevated inflammatory status, and "modified exercise" is currently proposed as being a good therapeutic help for these patients. However, the mechanisms involved in the exercise-induced benefits are still poorly understood. The objective was to evaluate the effect of a single bout of moderate cycling (45 min at 55% VO2 max) on the inflammatory (serum IL-8; chemotaxis and O2 (-) production by neutrophils; and IL-1β, TNF-α, IL-6, IL-10, and IL-18 release by monocytes) and stress (cortisol; NA; and eHsp72) responses in women diagnosed with FM compared with an aged-matched control group of healthy women (HW).

Effects of habitual exercise on the eHsp72-induced release of inflammatory cytokines by macrophages from obese Zucker rats.

Regular exercise is a good non-pharmacological treatment of metabolic syndrome in that it improves obesity, diabetes, and inflammation. The 72 kDa extracellular heat shock protein (eHsp72) is released during exercise, thus stimulating the inflammatory responses. The aim of the present work was to evaluate the effect of regular exercise on the eHsp72-induced release of IL-1β, IL-6, and TNFα by macrophages from genetically obese Zucker rats (fa/fa) (ObZ), using lean Zucker (LZ) rats (Fa/fa) to provide reference values.

Inflammatory/stress feedback dysregulation in women with fibromyalgia.

Objective: Although one of the current hypotheses of the aetiology of fibromyalgia (FM) syndrome involves inflammatory and neuroendocrine disorders, its biophysiology still remains unclear. The purpose of the present investigation was to study the systemic inflammatory and stress responses, as well as the innate response mediated by monocytes and neutrophils in FM patients.

Methods: Twenty-five women diagnosed with primary FM and 20 age-matched healthy women (control group) were enrolled in the study.

Hsp72, inflammation, and aging: causes, consequences, and perspectives.

Although aging is an inexorable component of life, its progress depends on how cumulative disruptions of homeostasis are compensated. Cumulative oxidative and inflammatory processes must be controlled to maintain successful aging. Heat shock proteins, such as those of the Hsp70 family, can be considered a danger signal, and their effects can either support longevity by neutralizing danger or can become detrimental when their production is not balanced.

Gender, obesity and repeated elevation of C-reactive protein: data from the CARDIA cohort.

C-reactive Protein (CRP) measurements above 10 mg/L have been conventionally treated as acute inflammation and excluded from epidemiologic studies of chronic inflammation. However, recent evidence suggest that such CRP elevations can be seen even with chronic inflammation. The authors assessed 3,300 participants in The Coronary Artery Risk Development in Young Adults study, who had two or more CRP measurements between 1992/3 and 2005/6 to a) investigate characteristics associated with repeated CRP elevation above 10 mg/L; b) identify subgroups at high risk of repeated elevation; and c) investigate the effect of different CRP thresholds on the probability of an elevation being one-time rather than repeated.

Aquatic exercise improves the monocyte pro- and anti-inflammatory cytokine production balance in fibromyalgia patients.

Current hypotheses of the etiology of fibromyalgia (FM) include inflammatory disorders. We evaluated the effect of a pool-aquatic exercise program (8 months, two weekly 60-min sessions) on the inflammatory cytokine production by isolated monocytes, and on the serum concentration of C-reactive protein (CRP), in a group of female FM patients. Monocytes from FM patients released more IL-1β, TNFα, IL-6, and IL-10 than those from an age-matched control group of healthy women (HW).

Exercise in fibromyalgia and related inflammatory disorders: known effects and unknown chances.

Fibromyalgia (FM) is characterised by chronic widespread pain and allodynia (pain from stimuli which are not normally painful with pain that may occur other than in the area stimulated) of more than 3 months duration. The current hypothesis of the aetiology of FM includes inflammatory and neuroendocrine disorders. The biophysiology of this syndrome, however; remains still widely elusive, and there are no formally approved therapies.

Gender and socio-economic patterning of self-reported sleep problems in Britain.

Sleep is fundamental to health and well-being, yet relatively little research attention has been paid to sleep quality. This paper addresses how socio-economic circumstances and gender are associated with sleep problems. We examine (i) socio-economic status (SES) patterning of reported sleep problems, (ii) whether SES differences in sleep problems can be explained by socio-demographic characteristics, smoking, worries, health and depression, and (iii) gender differences in sleep problems, addressing the relative contribution of SES, smoking, worries, health and depression in explaining these differences.
