Global scientific research on social participation of older people from 2000 to 2019: A bibliometric analysis

Abstract Background Social participation is an indicator of successful ageing and important determinant of health outcomes. As more studies have been conducted on social participation of older people, a comprehensive and quantitative analysis of the current literature will contribute to a better understanding of the main and novel issues and improve existing geriatric care services in this domain. However, limited bibliometric analysis was employed in this research field. Therefore, we conducted this study to investigate the research trend and quantitatively and comprehensively characterise the landscapes of publications on social participation of older people via bibliometric analysis methods. Methods Data were obtained from the Web of Science Core Collection in January 2020. CiteSpace 5.5. R2 and VOSviewer software packages were used to generate knowledge maps and analyse the publication outputs, countries/regions, institutions, journals, research hot spots and research frontiers. Results A total of 7,029 publications between 2000 and 2019 were retrieved, and the publication number per year continues to increase. The United States held a leading position in this research field, and Duke University was the most productive institution. Co‐cited reference cluster analysis and keyword co‐occurrence analysis showed that research hot spots contained factors of healthy ageing, quality of life, psychological problems and health status, especially dementia, function (including cognitive function) and frailty. Burst detection of keywords revealed that social participation, social support, instrumental activity, frailty and loneliness have been new research frontiers since 2015. Conclusions By analysing publications over the past 20 years, we found publication trends and characteristics in this field. These findings will hopefully provide new insight into the scientific landscapes and further directions in the study of social participation of older people. Implications for Practice Social participation is strongly associated with physical and psychological problems and the well‐being of older people. Related professionals, such as social workers, psychologists, nurses and many other health care practitioners, should raise widespread awareness and concern over research hot spots and frontiers on this topic to promote research knowledge translation and adoption into the practice of caring for older people.
In vitro and in vivo mammalian mutation assays support a nonmutagenic mechanism of carcinogenicity for hydrazine

Hydrazine has been described as a mutagenic, probable human carcinogen. It is mutagenic in in vitro systems such as bacterial reverse mutation (Ames) tests and some yeast systems, as well as in in vivo systems with drosophila. It was shown to cause chromosome damage both in vitro and in vivo but was negative in some well‐validated mammalian mutation systems such as CHO HPRT assays. Importantly, there is only one in vivo gene mutation test reported, which was negative. Our objective was to determine if hydrazine is mutagenic in mammalian test systems. Thus, we conducted an in vitro gene mutation test in Muta™Mouse lung epithelial cells (FE1 cell assay) and a regulatory‐compliant in vivo Big Blue® mouse test. Consistent with previous reports, an additional six‐well Ames assay showed that hydrazine was mutagenic to bacteria. The FE1 cell assay was negative in conditions with and without metabolic activation when tested to cytotoxicity limits. In the Big Blue® mouse study, female mice received dosages of hydrazine up to 10.9 mg/kg via drinking water for 28 days. This dose is comparable to a dose used in a carcinogenicity study where female mice had significant increases in hepatocellular adenoma at 11.5 mg/kg. There were no increases in mutant frequency in liver and lung, two tissues sensitive to the carcinogenic effects of hydrazine in mice. Our research shows that hydrazine is not mutagenic in mammalian cells either in vitro or in vivo, indicating mutagenicity may not play a role in the carcinogenicity of hydrazine.
A novel de novo SLC26A3 mutation causing congenital chloride diarrhea in a Japanese neonate

Congenital chloride diarrhea (CCD) is characterized by persistent chloride (Cl)‐rich diarrhea evident from birth. CCD is a rare autosomal recessive disorder caused by defects in the solute carrier family 26 member 3 (SLC26A3) gene, which encodes an intestinal Cl−/HCO3−, Na+‐independent exchanger. Various mutations of SLC26A3 have been described in CCD. However, no de novo mutations have been found to be responsible for CCD. Here we report the first such occurrence.
Trends in HbA1c thresholds for initiation of hypoglycemic agents: Impact of changed recommendations for older and frail patients

Less strict glycated hemoglobin (HbA1c) thresholds have been recommended in older and/or frail type 2 diabetes (T2D) patients than in younger and less frail patients for initiating hypoglycemic agents since 2011. We aimed to assess trends in HbA1c thresholds at initiation of a first hypoglycemic agent(s) in T2D patients and the influence of age and frailty on these trends.
Environmental Nanoparticles, SARS-CoV-2 Brain Involvement, and Potential Acceleration of Alzheimer's and Parkinson's Diseases in Young Urbanites Exposed to Air Pollution.

Alzheimer's and Parkinson's diseases (AD, PD) have a pediatric and young adult onset in Metropolitan Mexico City (MMC). The SARS-CoV-2 neurotropic RNA virus is triggering neurological complications and deep concern regarding acceleration of neuroinflammatory and neurodegenerative processes already in progress. This review, based on our MMC experience, will discuss two major issues: 1) why residents chronically exposed to air pollution are likely to be more susceptible to SARS-CoV-2 systemic and brain effects and 2) why young people with AD and PD already in progress will accelerate neurodegenerative processes. Secondary mental consequences of social distancing and isolation, fear, financial insecurity, violence, poor health support, and lack of understanding of the complex crisis are expected in MMC residents infected or free of SARS-CoV-2. MMC residents with pre-SARS-CoV-2 accumulation of misfolded proteins diagnostic of AD and PD and metal-rich, magnetic nanoparticles damaging key neural organelles are an ideal host for neurotrophic SARS-CoV-2 RNA virus invading the body through the same portals damaged by nanoparticles: nasal olfactory epithelium, the gastrointestinal tract, and the alveolar-capillary portal. We urgently need MMC multicenter retrospective-prospective neurological and psychiatric population follow-up and intervention strategies in place in case of acceleration of neurodegenerative processes, increased risk of suicide, and mental disease worsening. Identification of vulnerable populations and continuous effort to lower air pollution ought to be critical steps.
Variation of Shear Wave Elastography With Preload in the Thyroid

Thyroid shear wave elastography (SWE) has been shown to have advantages compared to biopsy or other imaging modalities in the evaluation of thyroid nodules. However, studies show variability in its assessment. The objective of this study was to evaluate whether stiffness measurements of the normal thyroid, as estimated by SWE, varied due to preload force or the pressure applied between the transducer and the patient.
Monoclonal antibodies in multiple myeloma.

Treatment of multiple myeloma (MM) patients has radically changed over the last years following the introduction of next generation proteasome inhibitors (PI) and immunomodulatory derivative (IMiDs). In the last years, one further therapeutic option for MM patients is represented by monoclonal antibodies (MoAbs), that seem to change the paradigm of MM treatment, particularly for heavily pretreated or double refractory to a PI and IMiDs patients. Antibodies have an immune-based mechanism, induce durable responses with limited toxicity and combine well with existing therapies. The therapeutic effects are prevalently obtained by means of antibody-dependent cellular cytotoxicity (ADCC), antibody-dependent cell-mediated phagocytosis (ADCP), complement-dependent cytotoxicity (CDC) and concurrently by the induction of signals on cell effectors. Immunotherapeutic strategies offer a new and exciting approach to target key molecular pathways that continue to be implicated in the survival of malignant plasma cells. These targets include cell surface proteins [CD38, CD138 (SDC1), B cell maturation antigen (BCMA, TNFRSF17)], cytokines that play a role in plasma cell survival and proliferation [interleukin 6 (IL6) and B cell activating factor], signal regulators of bone metabolism [RANKL (TNFSF11), DKK1] and regulators of the immune system [PD-1(PDCD1), PD-L1(CD274)]. This article will focus on new MoAbs and related innovative immunotherapeutic modalities currently under investigation in the treatment landscape of MM.
How Do You Treat Irritable Bowel Syndrome in Your Practice?

Irritable Bowel Syndrome (IBS) is a gastrointestinal (GI) mobility disorder causing recurring upper and lower GI symptoms—bloating, constipation/diarrhea, and varying degrees of abdominal pain. IBS-C refers to constipation, IBS-D refers to diarrhea, IBS-M refers to mixed, and IBS-U refers to unsubtyped. The worldwide incidence of IBS is 10%–20%; Asian and Western populations are similarly affected. Diagnosis is made by symptoms alone in the absence of ‘‘red flags,’’ such as age of onset older than 50, rectal bleeding, weight loss, family history of inflammatory bowel disease, systemic signs of infection, or colitis. There are no specific tests. It is important to exclude colon cancer, giardiasis, thyroid disorders, carcinoid syndrome, microscopic colitis, bacterial overgrowth, and eosinophilic gastroenteritis. If the patient’s history is typical and physical examination, colonoscopy, blood count, erythrocyte sedimentation rate, C-reactive protein, thyroid function testing, and three fecal occult blood examinations yield normal findings, a diagnosis of IBS can be made with confidence. Rome Criteria for diagnosis (Rome IV) include abdominal pain and discomfort lasting on average of 1 day per week in the previous 3 months, associated with at least two of the factors, such as pain and discomfort related to defecation, and alteration in the frequency of defecation or stool consistency. Modern biomedicine treatment involves fiber supplements, laxatives, antidiarrheal medications, antispasmodics (20 mg of hyoscine t.i.d.), tricyclic antidepressants, selective serotonin reuptake inhibiters, pregabalin, gabapentin, alosetron (to relax the colon), eluxadoline (to reduce diarrhea), rifaximin (to decrease bacterial growth in the colon), lubiprostone (to reduce constipation), and enteric-coated peppermint oil (to ease bloating and pain). Iberogast, an herbal extract, has been found to be significantly better than placebo.
Aceites esenciales modificadores de perfiles de fermentación ruminal y mitigación de metano en rumiantes. Revisión Ruminal fermentation modification and methanogenesis mitigation by essential oils from plants. Review

Methane production in ruminant livestock systems has been controlled traditionally through antibiotic use. However, these have been banned in Europe since 2006 and will soon be banned on other continents. In response, research has focused on identifying synthetic and natural compounds with antimicrobial properties that do not foster microorganism resistance. Plant secondary components such as essential oils are receiving increasing attention. To date, only 70 essential oils and their main active principles have been tested to determine their effect on ruminal fermentation modification and/or methane mitigation. Most studies addressing these phenomena have been in vitro, and some report significant modification and/or mitigation action. In vivo studies including productive parameters have only recently been carried out. An overview is done of in vitro and in vivo research into the effects of essential oils on the main parameters of ruminal fermentation, methane mitigation, production performance and immune condition, and suggestions made for future research.
Heart-Microcirculation Connection

Supplemental Digital Content is available in the text. Cardiac ANP (atrial natriuretic peptide) moderates arterial blood pressure. The mechanisms mediating its hypotensive effects are complex and involve inhibition of the renin-angiotensin-aldosterone system, increased natriuresis, endothelial permeability, and vasodilatation. The contribution of the direct vasodilating effects of ANP to blood pressure homeostasis is controversial because variable levels of the ANP receptor, GC-A (guanylyl cyclase-A), are expressed among vascular beds. Here, we show that ANP stimulates GC-A/cyclic GMP signaling in cultured microvascular pericytes and thereby the phosphorylation of the regulatory subunit of myosin phosphatase 1 by cGMP-dependent protein kinase I. Moreover, ANP prevents the calcium and contractile responses of pericytes to endothelin-1 as well as microvascular constrictions. In mice with conditional inactivation (knock-out) of GC-A in microcirculatory pericytes, such vasodilating effects of ANP on precapillary arterioles and capillaries were fully abolished. Concordantly, these mice have increased blood pressure despite preserved renal excretory function. Furthermore, acute intravascular volume expansion, which caused release of cardiac ANP, did not affect blood pressure of control mice but provoked hypertensive reactions in pericyte GC-A knock-out littermates. We conclude that GC-A/cGMP–dependent modulation of pericytes and microcirculatory tone contributes to the acute and chronic moderation of arterial blood pressure by ANP.

Comparison between a transurethral prostate split and transurethral prostate resection for benign prostatic hyperplasia treatment in a small prostate volume: a prospective controlled study

Background Transurethral resection of the prostate (TURP) was considered the golden standard to treat benign prostatic hyperplasia (BPH) for decades. However, TURP was associated with low efficiency to alleviate the lower urinary tract symptoms (LUTS) and a significantly higher risk of bladder neck contracture (BNC) for patients with small-volume BPH. Our study aims to compare the therapeutic effect of a transurethral split of the prostate (TUSP) with TURP for patients with small-volume BPH (<30 mL). Methods In this study, 101 small-volume BPH patients were randomly divided into two groups (TUSP and TURP group). The patient’s baseline characteristics and perioperative outcomes were recorded. The follow-up was done at six months, one year and two years after surgical treatment. Results No significant differences were observed between the two groups for the baseline characteristics, including age, prostate volume, prostate-specific antigen (PSA) level, concurrent disease, post-void residual (PVR), maximum urinary flow rate (Qmax), international prostate symptoms score (IPSS), and quality of life (QoL) score. The operative time and hemoglobin decrease were significantly lower in the TUSP group compared to the TURP group. However, no significant differences were observed between both groups for catheterization time, postoperative hospital stay, and incidence of transurethral resection syndrome (TURS). However, of the late complications, the incidence of BNC in the TUSP group was significantly lower than the TURP group. No significant differences were found between both groups for other complications, including postoperative bleeding, micturition urgency, micturition frequency, micturition pain, urinary tract infection, recatheterization, transient incontinence, and continuous incontinence. Follow-up results showed that the IPSS of the TUSP group was significantly lower than the TURP group, while the Qmax of the TUSP group was significantly higher than the TURP group. Conclusions This study shows that TUSP may be an efficient and safe treatment for small-volume BPH (<30 mL) with a lower incidence of postoperative BNC and better longtime clinical outcomes than TURP. It suggested that TUSP could be an ideal treatment choice for small-volume BPH.
A cross-sectional study on the relationship between homocysteine and lipid profiles among Chinese population from Hunan.

Previous studies have explored the relationship between homocystein (Hcy) and lipid profiles. However, the results from these studies have been inconsistent. The current study investigated the correlation between Hcy and lipid profiles in Chinese community-based population. The participants were composed of 4012 Chinese people aged 30-92 years old, who were recruited from rural and urban communities in the Hunan Province. Non-parametric test and logistic regression were used to examine the distribution of Hcy and lipid profiles (triglyceride [TG], total cholesterol [TC], low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C]) and the relationship between them. The median age of subjects was 54.50 years old, and 40.98% were male. Median Hcy was 13.20 μmol/L, and 35.39% had hyperhomocysteinemia (HHcy). Median TG was 1.51 mmol/L, TC was 4.77 mmol/L, LDL-C was 2.62 mmol/L, and HDL-C was 1.27 mmol/L. In multivariable logistic regression analysis, HHcy was associated with high levels of TG (ORmale = 2.240, p < 0.001; ORfemale = 2.539, p < 0.001), TC (ORmale = 2.237, p < 0.001; ORfemale = 2.202, p < 0.001), and LDL-C (ORmale = 1.413, p = 0.010; ORfemale = 1.617, p < 0.001) in the different sexes population and low level of HDL-C in females (OR = 1.326, p = 0.023) after adjusting for confounders. HHcy was independently associated with an increasing risk of low HDL-C among females. The regression analysis showed that HHcy was also associated with hypertriglyceridemia, hypercholesterolemia, and high level of LDL-C in males and females from Chinese community-based population, which provides a basis for the treatment and prevention of abnormal lipid metabolism.
Small nucleolar RNA host gene 22 (SNHG22) promotes the progression of esophageal squamous cell carcinoma by miR-429/SESN3 axis

Background It has been observed that lncRNAs have been taking part in many cancer progressions, including non-small cell lung cancer and gastric cancer. Meanwhile, lncRNA small nucleolar RNA host gene 22 (SNHG22) has been studied, taking part in the progression of ovarian epithelial carcinoma. However, we know little about the function of SNHG22 in esophageal squamous cell carcinoma (ESCC). Methods In this study, we will explore the inner mechanism of SNHG22 in ESCC. Quantitative real-time PCR (qRT-PCR) assay was implemented in ESCC cells for detecting the expression of lncRNA, SNHG22, and miR-429. Also, functional experiments, including CCK8 and colony formation assay, were implemented to assess the growth of ESCC cells. Meanwhile, flow cytometry analysis was conducted to test the apoptosis of ESCC cells. The immunofluorescence (IF) assay and western blot were conducted to verify the autophagy of ESCC cells. Results Inhibition of SNHG22 was found that can inhibit the progression and promotes autophagy and apoptosis of ESCC cells. Meanwhile, as subcellular fraction assay and FISH assay found that SNHG22 mainly in the cytoplasm, miR-429 was found can bind to SNHG22 and SESN3 by RIP assay and luciferase reporter assay. SESN3 was found it can play the oncogene in ESCC cells. Conclusions SNHG22 promotes the progression of ESCC by the miR-429/SESN3 axis.
Visually guided associative learning in pediatric and adult migraine without aura

Introduction The Rutgers Acquired Equivalence Test is a visually guided equivalence learning paradigm that involves rule acquisition and generalization. Earlier we found impaired performance in this paradigm among adult migraine patients without aura. The aim of the study was to investigate if similar impairments can be found already in the pediatric form of the disease and to compare the performance of the pediatric study population with that of an adult study population. We hypothesized that the deficits observed in adults would be observable already in the pediatric population. Methods Twenty-seven children and adolescents newly diagnosed with migraine without aura and 27 age- and sex-matched healthy controls were tested with the Rutgers Acquired Equivalence Test. Their performance data were compared to each other and those of an earlier adult study population involving 22 patients and 22 age- and sex-matched healthy controls. Four parameters characterizing performance in the two main phases of the paradigm were calculated for each of the four groups. Performance parameters were compared with Mann-Whitney U test. Results In contrast to the decreased performance of the adult patients in the Rutgers Acquired Equivalence Test, no significant difference was found between pediatric patients and controls in any phase of the paradigm. Conclusion Children living with migraine without aura do not exhibit the same cognitive deficits in the Rutgers Acquired Equivalence Test as their adult counterparts. It can be hypothesized that the deficit of equivalence learning is not an inherent feature of the migrainous cognitive profile, rather the result of the interference of the disease with normal development.
Emotional distractors and attentional control in anxious youth: eye tracking and fMRI data

ABSTRACT Attentional control theory suggests that high cognitive demands impair the flexible deployment of attention control in anxious adults, particularly when paired with external threats. Extending this work to pediatric anxiety, we report two studies utilising eye tracking (Study 1) and functional magnetic resonance imaging (Study 2). Both studies use a visual search paradigm to examine anxiety-related differences in the impact of threat on attentional control at varying levels of task difficulty. In Study 1, youth ages 8–18 years (N = 109), completed the paradigm during eye tracking. Results indicated that youth with more severe anxiety took longer to fixate on and identify the target, specifically on difficult trials, compared to youth with less anxiety. However, no anxiety-related effects of emotional distraction (faces) emerged. In Study 2, a separate cohort of 8–18-year-olds (N = 72) completed a similar paradigm during fMRI. Behaviourally, youth with more severe anxiety were slower to respond on searches following non-threatening, compared to threatening, distractors, but this effect did not vary by task difficulty. The same interaction emerged in the neuroimaging analysis in the superior parietal lobule and precentral gyrus-more severe anxiety was associated with greater brain response following non-threatening distractors. Theoretical implications of these inconsistent findings are discussed.
