Group Medical Visits Versus Usual Care for Illness Perception and Hypertension: A Randomized Pilot Study

ABSTRACT Despite separate evidence regarding illness perception (IP) and group medical visits (GMVs) for hypertension, research on both is limited. Here, we have assessed and compared the effectiveness of GMVs and usual care (UC) on IP and blood pressure (BP) in patients with hypertension. This was a two-group parallel randomized controlled study with 1:1 allocation. Patients with essential hypertension on antihypertensive medication and no cognitive impairments were screened for BP control status and eligibility. A web-based program randomly assigned them to the GMV and UC groups. Group medical visits were held once a month for 3 months. Primary and secondary outcome measures included improvements in IP and BP control. Among 152 participants, 40 and 43 were assigned to the GMV and UC groups, respectively. The control group had a 9.3% dropout rate. The chronic timeline and illness coherence improved significantly in the intervention group (p < .01). Systolic BP in the intervention group decreased significantly compared with that of the control group (Δ: −18.8 ± 18.4 mm Hg vs. Δ: −10.6 ± 12.5 mm Hg, p = .025). The participation in GMVs had a significant association with the odds of an increase in BP regulation (OR 3.8, 95% confidence interval 1.4–10.3, p = .007). Therefore, GMVs may be feasible for BP control in hypertensive patients with similar characteristics.
Prevalence and associated risk factors for elevated blood pressure in young adults in South Africa.

BACKGROUND Sub-Saharan Africa has been shown to have a high prevalence of hypertension (58% in rural black South Africans) with an accelerated course ending in end-stage renal disease. We sought to determine whether the prevalence of elevated blood pressure (EBP) in early adulthood was associated with any risk factors and/or renal target-organ damage in young adulthood, which could prevent development of these cardiorenal sequelae. METHODS Data including risk factors for hypertension and markers of kidney damage were collected from young adults (n = 933; age 28 years; 52% female) participating in the Birth to Twenty Plus (BT20) cohort in Soweto, South Africa. Blood pressure was measured on one occasion. RESULTS Fifty-four per cent of the study sample had EBP with more men affected (62%) than women (47%) (p < 0.001). Body mass index (BMI), hyperuricaemia and albuminuria had significant associations with EBP in men. In women, BMI, hyperuricaemia and a self-reported history of gestational hypertension had significant associations. CONCLUSIONS Our findings suggest that the pathophysiology of EBP in young adults differs between the genders and highlights a number of modifiable factors in its development.
Latent structure of working memory and emotion regulation in pediatric ADHD

ABSTRACT Working memory is a key cognitive function that is often implicated in ADHD and may represent an underlying cognitive endophenotype of the disorder. Working memory is related to emotion regulation, which is a common area of impairment in children with ADHD. Given the high rate of comorbid diagnoses with ADHD, children with comorbid internalizing, externalizing, and developmental disorders may present with variable working memory profiles and subsequent emotion regulation deficits. This study aimed to adequately characterize the latent structure of working memory impairments and emotional regulation outcomes in a clinical sample of children ages 6–16 with ADHD. This study also examined the interplay between the identified working memory/emotion regulation patterns, demographic characteristics, and the role of comorbid diagnoses. Results highlighted two distinct, invariant, unrestricted classes of working memory/emotion regulation. Class 1 (Average; 62% of the sample) had significantly lower digit-span scores, and generally persevered emotion regulation functioning per parent/teacher report. Class 2 (Emotionally Dysregulated) had average working memory scores, and elevated emotion regulation problems. The working memory indicators had small correlations with parents (and not teacher) measures of emotion regulation. Finally, latent class membership did not differ by comorbid diagnosis, age, gender, or verbal IQ. Findings elucidate heterogeneity in common domains affected by ADHD and suggest that this heterogeneity may not be due to demographic/comorbidity factors. The role of varying information reports is discussed, and potential assessment and treatment implications are highlighted.
Confronting the unknown—Nursing surveillance of COVID‐19‐infected patients through remote telephone calls and in an on‐site urgent clinic

Abstract Aim To describe nursing surveillance of coronavirus disease 2019 (COVID‐19)‐infected patients through remote telephone calls and in an on‐site urgent clinic during the first wave of the pandemic as experienced by nurses providing the care. Design Qualitative descriptive study. Methods Data were collected through seven semi‐structured, audio‐recorded, focus group interviews with 24 nurses. Interviews were conducted in May and June 2020, transcribed and analysed using deductive and inductive content analysis into an overarching category, main categories and subcategories. Reporting followed the COREQ guidelines. Results Nurses relied on intensive listening when assessing and caring for COVID‐19‐infected patients. They realized that the patients had complex needs for nursing and healthcare which was beyond the scope of a tentatively prescribed assessment scheme. They designed their care to ensure holistic care, reflected in the overarching category, ‘Confronting an unfamiliar health condition in unprecedented circumstances’ and the categories: ‘Digging into the unknown’ and ‘Ensuring holistic nursing care’. The category ‘Contributing to averting catastrophe’ reflects the wealth of knowledge, support and experience that the nurses used to independently deliver care, albeit in interdisciplinary collaboration, working to their greatest potential. They were proud of the significance of their work. Conclusion Novel nursing surveillance through remote telephone calls and in an on‐site urgent care clinic delivered to COVID‐19 patients self‐managing at home resulted in holistic nursing care during the first wave of the pandemic. This has relevance for professionalism in nursing. Impact Findings give a unique insight into nursing surveillance of COVID‐19‐infected patients provided through telephone calls and in on‐site urgent care clinics. The potential of intensive listening as conducted in the study suggests that it may be feasible to assess and holistically take care of COVID‐19‐infected patients, and other patient groups as well, with this form of healthcare. This has relevance for healthcare beyond crisis management during pandemics. Patient or Public Contribution There was no patient or public contribution as the study only concerned the providers of the service, i.e. the nurses themselves.
Relationship Between Prognostic Nutritional Index and Contrast-Associated Acute Kidney Injury in Patients With Non-ST Segment Elevation Myocardial Infarction Undergoing Coronary Angiography

Prognostic nutritional index (PNI), consisting of inflammatory-nutritional parameters, has been investigated in terms of outcomes and renal function in patients with coronary artery disease. The objective of this study is to assess the predictive power of the PNI in predicting the risk for developing contrast-associated acute kidney injury (CA-AKI), an important complication following coronary angiography in patients with non-ST-elevation myocardial infarction (NSTEMI). The study population (336 patients with the diagnosis of NSTEMI) was divided into two groups: patients with CA-AKI and patients without CA-AKI. The mean age of the whole population was 62.0 ± 12.7 (21–95) years. CA-AKI was detected in 68 (20%) patients. Prognostic nutritional index values were significantly (P < .001) lower in the CA-AKI (+) group. Low PNI values (cutoff < 48.5%) were independent predictors of CA-AKI with Odds ratio (OR): . 913, 95% confidence interval (CI): . 866–. 962, P:. 001, with a sensitivity 70.6% and specificity 69.4%. Prognostic nutritional index seems to be an easily assessable and promising scoring system that can be used in clinical practice for predicting the risk of developing CA-AKI.
Mutations of TRPM8 channels: Unraveling the molecular basis of activation by cold and ligands

The cation nonselective channel TRPM8 is activated by multiple stimuli, including moderate cold and various chemical compounds (i.e., menthol and icilin [Fig. 1], among others). While research continues growing on the understanding of the physiological involvement of TRPM8 channels and their role in various pathological states, the information available on its activation mechanisms has also increased, supported by mutagenesis and structural studies. This review compiles known information on specific mutations of channel residues and their consequences on channel viability and function. Besides, the comparison of sequence of animals living in different environments, together with chimera and mutagenesis studies are helping to unravel the mechanism of adaptation to different temperatures. The results of mutagenesis studies, grouped by different channel regions, are compared with the current knowledge of TRPM8 structures obtained by cryo‐electron microscopy. Trying to make this review self‐explicative and highly informative, important residues for TRPM8 function are summarized in a figure, and mutants, deletions and chimeras are compiled in a table, including also the observed effects by different methods of activation and the corresponding references. The information provided by this review may also help in the design of new ligands for TRPM8, an interesting biological target for therapeutic intervention.
Association of Prehospital Needle Decompression With Mortality Among Injured Patients Requiring Emergency Chest Decompression.

Importance Prehospital needle decompression (PHND) is a rare but potentially life-saving procedure. Prior studies on chest decompression in trauma patients have been small, limited to single institutions or emergency medical services (EMS) agencies, and lacked appropriate comparator groups, making the effectiveness of this intervention uncertain. Objective To determine the association of PHND with early mortality in patients requiring emergent chest decompression. Design, Setting, and Participants This was a retrospective cohort study conducted from January 1, 2000, to March 18, 2020, using the Pennsylvania Trauma Outcomes Study database. Patients older than 15 years who were transported from the scene of injury were included in the analysis. Data were analyzed between April 28, 2021, and September 18, 2021. Exposures Patients without PHND but undergoing tube thoracostomy within 15 minutes of arrival at the trauma center were the comparison group that may have benefited from PHND. Main Outcomes and Measures Mixed-effect logistic regression was used to determine the variability in PHND between patient and EMS agency factors, as well as the association between risk-adjusted 24-hour mortality and PHND, accounting for clustering by center and year. Propensity score matching, instrumental variable analysis using EMS agency-level PHND proportion, and several sensitivity analyses were performed to address potential bias. Results A total of 8469 patients were included in this study; 1337 patients (11%) had PHND (median [IQR] age, 37 [25-52] years; 1096 male patients [82.0%]), and 7132 patients (84.2%) had emergent tube thoracostomy (median [IQR] age, 32 [23-48] years; 6083 male patients [85.3%]). PHND rates were stable over the study period between 0.2% and 0.5%. Patient factors accounted for 43% of the variation in PHND rates, whereas EMS agency accounted for 57% of the variation. PHND was associated with a 25% decrease in odds of 24-hour mortality (odds ratio [OR], 0.75; 95% CI, 0.61-0.94; P = .01). Similar results were found in patients who survived their ED stay (OR, 0.68; 95% CI, 0.52-0.89; P < .01), excluding severe traumatic brain injury (OR, 0.65; 95% CI, 0.45-0.95; P = .03), and restricted to patients with severe chest injury (OR, 0.72; 95% CI, 0.55-0.93; P = .01). PHND was also associated with lower odds of 24-hour mortality after propensity matching (OR, 0.79; 95% CI, 0.62-0.98; P = .04) when restricting matches to the same EMS agency (OR, 0.74; 95% CI, 0.56-0.99; P = .04) and in instrumental variable probit regression (coefficient, -0.60; 95% CI, -1.04 to -0.16; P < .01). Conclusions and Relevance In this cohort study, PHND was associated with lower 24-hour mortality compared with emergent trauma center chest tube placement in trauma patients. Although performed rarely, PHND can be a life-saving intervention and should be reinforced in EMS education for appropriately selected trauma patients.
Distributive Conjunction and Sentence Reduction

The paper argues that the distributive conjunction construction formed in English byboth XP and XPand in Italian bysia XP che XPis best analyzed as a sentential conjunction which is reduced by a combination of fronting operations and cross-the-board raising. The distribution of this type of conjunction has a number of pecu liar restrictions, compared to ‘plain’ conjunction. The analysis accounts for these res trictions by showing that there is strong correlation between constituents which my appear in both/andandsia/cheand constituents which may undergo A-bar fronting. The analysi s i extended to certain DPinternal cases, and differences between the English and the Italian construction are reduced to general properties of the two languages.
‘Torn in two’: Experiences of Mothers Who Are Pregnant when Their Child Is Diagnosed With Cancer

Mothers of children diagnosed with cancer have been shown to experience high rates of psychological distress and poor physical health. Pregnancy further increases the healthcare needs of mothers due to the marked physiological changes and psychological adaptations. Our study aimed to explore the experiences of mothers who were pregnant and/or had a baby while their older child was receiving treatment for cancer. Our study employed a qualitative description methodology using semi-structured interviews. Participants were recruited from across Australia via notices on social media sites and the distribution of flyers. The sample comprised 13 mothers who were pregnant and/or had a baby and had a child diagnosed with cancer who was under 17 years old. Thematic analysis was used to analyse the data from which six themes were identified: (1) an impossible balancing act, (2) mother’s health and well-being, (3) creating certainty: birthing plans, (4) a bit of sunshine and a time to rest, (5) challenges of caring for the baby and (6) an unenviable position: doing my best versus feeling guilty. Our study demonstrates the additional challenges faced by mothers who are pregnant while their child is receiving cancer treatment. There is a need for a comprehensive and coordinated program that provides pregnant mothers with practical and psychological support. The implementation of such a program has the potential to improve health outcomes for all family members, particularly the mother and their newborn.
Periplasmic Bacterial Biomineralization of Copper Sulfide Nanoparticles

Metal sulfides are a common group of extracellular bacterial biominerals. However, only a few cases of intracellular biomineralization are reported in this group, mostly limited to greigite (Fe3S4) in magnetotactic bacteria. Here, a previously unknown periplasmic biomineralization of copper sulfide produced by the magnetotactic bacterium Desulfamplus magnetovallimortis strain BW‐1, a species known to mineralize greigite (Fe3S4) and magnetite (Fe3O4) in the cytoplasm is reported. BW‐1 produces hundreds of spherical nanoparticles, composed of 1–2 nm substructures of a poorly crystalline hexagonal copper sulfide structure that remains in a thermodynamically unstable state. The particles appear to be surrounded by an organic matrix as found from staining and electron microscopy inspection. Differential proteomics suggests that periplasmic proteins, such as a DegP‐like protein and a heavy metal‐binding protein, could be involved in this biomineralization process. The unexpected periplasmic formation of copper sulfide nanoparticles in BW‐1 reveals previously unknown possibilities for intracellular biomineralization that involves intriguing biological control and holds promise for biological metal recovery in times of copper shortage.
An increase of inhibition drives the developmental decorrelation of neural activity

Throughout development, the brain transits from early highly synchronous activity patterns to a mature state with sparse and decorrelated neural activity, yet the mechanisms underlying this process are poorly understood. The developmental transition has important functional consequences, as the latter state is thought to allow for more efficient storage, retrieval, and processing of information. Here, we show that, in the mouse medial prefrontal cortex (mPFC), neural activity during the first two postnatal weeks decorrelates following specific spatial patterns. This process is accompanied by a concomitant tilting of excitation-inhibition (E-I) ratio toward inhibition. Using optogenetic manipulations and neural network modeling, we show that the two phenomena are mechanistically linked, and that a relative increase of inhibition drives the decorrelation of neural activity. Accordingly, in mice mimicking the etiology of neurodevelopmental disorders, subtle alterations in E-I ratio are associated with specific impairments in the correlational structure of spike trains. Finally, capitalizing on EEG data from newborn babies, we show that an analogous developmental transition takes place also in the human brain. Thus, changes in E-I ratio control the (de)correlation of neural activity and, by these means, its developmental imbalance might contribute to the pathogenesis of neurodevelopmental disorders.
A logistic regression model based on inpatient health records to predict drug-induced liver injury caused by ramipril—An angiotensin-converting enzyme inhibitor

Drug-induced liver injury (DILI) is a rare side effect of angiotensin-converting enzyme inhibitors (ACEIs). Ramipril is a widely used ACE compound because of its effectiveness in the treatment of hypertension and heart failure, as well as its low risk of adverse effects. However, the clinical features of ramipril, and the risk of DILI, have not been adequately studied. A retrospective cohort study was performed based on data from 3909 inpatients to compare the risk of DILI conferred by ramipril and other ACEIs. A logistic regression model was then constructed and validated against data from 1686 patients using ramipril, of which 117 patients were diagnosed with DILI. The use of ramipril increased the risk of DILI by 2.68 times (odds ratio = 2.68; 95% confident interval (CI):1.96–3.71) compared with the group using other ACEIs. The clinical features of DILI in the ramipril group were similar to those from the ACEI group (P>0.05), except that the ALT level was higher (P<0.05). A logistic regression model including Body mass index (BMI), comorbidity, liver disease, daily dose, alanine aminotransferase (ALT), and alkaline phosphatase (ALP) was built and successfully validated for DILI risk prediction, with the area under the receiver operating characteristic curve of the model of 0.82 (95% CI: 0.752–0.888). We recommend that clinicians should be aware of the levels of ALT and ALP as well as BMI, comorbidities, and liver disease before prescribing ramipril to avoid the risk of DILI in patients.
Patients and healthcare professionals perspectives on creating a chronic pain support line in Portugal: A qualitative study protocol

Chronic pain affects almost 38% of the Portuguese adult population, with high costs for both patients and society. Those who suffer with chronic pain frequently complain of feeling misunderstood and of lack of support. These complaints are the main reason why support telephone lines for chronic pain were created in some countries. However, there is no scientific data supporting their creation or evaluating their performance. This paper presents a qualitative study protocol to assess patients and healthcare professionals’ perspectives on the creation of a telephone support line for chronic pain. It constitutes the first step to attain the main goal of developing and implementing a functioning support line for chronic pain in Portugal. The methodology to assess patients and healthcare professionals’ perspectives and needs is presented. In order to gather information as close to reality as possible, focus groups interviews were chosen as data sources. Given the present context of the COVID-19 pandemic, meetings will take place online, using a digital platform. All interviews will be transcribed verbatim, coded and synthesised into categories and main themes. Thematic analysis will be conducted using NVivo® V12 software, employing an iterative and reflexive approach. Finally, comparative and relational analysis will be performed in order to identify topics where patients and professionals converge or greatly diverge. The findings will be useful for grounding the creation of a telephone support line for chronic pain patients. Results dissemination will be important for policy-makers to develop a new perspective towards chronic pain services available.
Effects of lifelong spontaneous exercise on skeletal muscle and angiogenesis in super-aged mice

There has been an increasing awareness of sarcopenia, which is characterized by a concomitant decrease in skeletal muscle mass and quality due to aging. Resistance exercise is considered more effective than aerobic exercise in terms of therapeutic exercise. To confirm the effect of long-term aerobic exercise in preventing sarcopenia, we evaluated the skeletal muscle mass, quality, and angiogenic capacity of super-aged mice that had undergone lifelong spontaneous exercise (LSE) through various experiments. Our findings show that LSE could maintain skeletal muscle mass, quality, and fitness levels in super-aged mice. In addition, ex vivo experiments showed that the angiogenic capacity was maintained at a high level. However, these results were not consistent with the related changes in the expression of genes and/or proteins involved in protein synthesis or angiogenesis. Based on the results of previous studies, it seems certain that the expression at the molecular level does not represent the phenotypes of skeletal muscle and angiogenesis. This is because aging and long-term exercise are variables that can affect both protein synthesis and the expression patterns of angiogenesis-related genes and proteins. Therefore, in aging and exercise-related research, various physical fitness and angiogenesis variables and phenotypes should be analyzed. In conclusion, LSE appears to maintain the potential of angiogenesis and slow the aging process to maintain skeletal muscle mass and quality. Aerobic exercise may thus be effective for the prevention of sarcopenia.
