Computed Tomography Findings Suggestive of Connective Tissue Disease in the Setting of Usual Interstitial Pneumonia

Purpose A usual interstitial pneumonia (UIP) pattern is common in idiopathic pulmonary fibrosis (IPF) and connective tissue disease–related interstitial lung disease (CTD-ILD). The purpose of the study was to validate imaging findings differentiating CTD-ILD from IPF in UIP. Methods Patients with a multidisciplinary diagnosis of CTD-ILD or IPF and a UIP pattern on computed tomography and/or pathology were included in this study. Prevalence of 3 computed tomography findings shown to be associated with CTD-ILD (the straight edge sign [SES], the exuberant honeycombing sign, and the anterior upper lobe sign [AULS]) were tabulated in CTD-ILD and IPF subjects. The ability of each of these signs to discriminate between CTD-ILD and IPF was evaluated. Survival analysis was also performed using log-rank analysis. Results The study cohort included 50 CTD-ILD and 100 IPF subjects with UIP. The SES and the AULS were more common in CTD-ILD than IPF (prevalence, 36.0% and 34.9% in CTD-ILD vs 8.3% and 17.2% in IPF, respectively [P = 0.0105 − <0.001]). The highest specificity (95.7%) of CTD-ILD diagnosis was seen with bilateral SES. Moreover, the SES was associated with improved survival (P = 0.0383), which appeared to be largely because of improvement in survival in IPF subjects. The presence of AULS was associated with pulmonary functional abnormalities. Conclusions A radiographic UIP pattern with evidence of SES or the AULS should raise suspicion for CTD-ILD rather than IPF. Patients with IPF and SES have an attenuated disease course and might represent a different phenotype than those without the SES.
Reactions to Laboratory-Based Trauma Research in a Sample of Incarcerated Women

An evidence-based approach to research ethics is critical to ethical research but little is known about how trauma survivors—especially those from vulnerable populations—respond to laboratory-based trauma research. One hundred four incarcerated women (N = 64 rape survivors) reported their traumatic life experiences, listened to and responded to an audio recording of a dating interaction that culminates in a completed rape, and then reported their responses to their participation. Compared to the control group (N = 40), rape survivors (N = 64) had more posttraumatic stress disorder symptoms and these symptoms were associated with more emotional responding. Both groups showed a positive benefit–cost ratio with regard to their participation did not differ on their overall reactions to research participation. These findings suggest that laboratory-based trauma research methods are associated with consistently positive experiences, which can help inform researchers and institutional review boards about the risks and benefits of such research.
Head-to-Head Comparison of 8 Plasma Amyloid-β 42/40 Assays in Alzheimer Disease

Key Points Question How well does plasma amyloid-β 42/40 (Aβ42/40), measured using 8 different assays, detect brain Aβ pathology in the early stages of Alzheimer disease? Findings In this study, including 408 participants from 2 independent cohorts (BioFINDER and Alzheimer Disease Neuroimaging Initiative), plasma Aβ42/40 quantified using certain mass spectrometry–based methods showed better discriminative accuracy than immunoassays when identifying individuals with abnormal intracerebral Aβ status according to cerebrospinal fluid Aβ42/40 levels and Aβ positron emission tomography. Meaning Certain mass spectrometry–based plasma tests might have sufficient performance to detect brain Aβ pathology in Alzheimer disease.
Absolute Temperature Thresholds for Detection of Skin Wetness and Dampness on the Hand and their Variation with Sex and Age

The human body has dedicated receptors for sensing temperature and touch, but not wetness. How then is wetness perceived? To test if wetness perception arises from the sensory integration of touch and temperature, and to quantify its measurement in humans, we designed a wetness perception monitor (WPM) which enabled variation of temperature at the fingertips of participants while measuring the pressure exerted on a test surface in the controlled environment of a moisture-free chamber. Thirty randomly selected adults (18+ years) were tested for their perception of dampness/wetness using the WPM. Our data suggest that humans perceive dampness and wetness at average temperatures of 22 ± 0.4°C and 18 ± 0.5°C, respectively, and these sensations are extinguished at temperatures below 16 ± 1°C. Measurements were obtained at an average tactile pressure of 1.5 ± 0.3 kPa. Young adults (18–35 years) sensed wetness at significantly higher temperatures than middle-aged adults (36–55 years) or mature adults (56+ years), who sensed wetness at similar temperatures. We found a surprising sex difference in wetness perception, with females sensing wetness at higher temperatures than males. When the data were screened for outliers, we found that participants whose readings were outside normal ranges, self-reported sensory deficits suggesting that wetness perception could potentially be used as a noninvasive biomarker.
Coding and Noncoding Variation in LRRK2 and Parkinson's Disease Risk

The leucine‐rich repeat kinase 2 (LRRK2) gene harbors both rare highly damaging missense variants (eg, p.G2019S) and common noncoding variants (eg, rs76904798) with lower effect sizes that are associated with Parkinson's disease (PD) risk.
SMA-miRs (miR-181a-5p, -324-5p, and -451a) are overexpressed in spinal muscular atrophy skeletal muscle and serum samples

Background: Spinal muscular atrophy (SMA) is a neuromuscular disorder characterized by the degeneration of the second motor neuron. The phenotype ranges from very severe to very mild forms. All patients have the homozygous loss of the SMN1 gene and a variable number of SMN2 (generally 2–4 copies), inversely related to the severity. The amazing results of the available treatments have made compelling the need of prognostic biomarkers to predict the progression trajectories of patients. Besides the SMN2 products, few other biomarkers have been evaluated so far, including some miRs. Methods: We performed whole miRNome analysis of muscle samples of patients and controls (14 biopsies and 9 cultures). The levels of muscle differentially expressed miRs were evaluated in serum samples (51 patients and 37 controls) and integrated with SMN2 copies, SMN2 full-length transcript levels in blood and age (SMA-score). Results: Over 100 miRs were differentially expressed in SMA muscle; 3 of them (hsa-miR-181a-5p, -324-5p, -451a; SMA-miRs) were significantly upregulated in the serum of patients. The severity predicted by the SMA-score was related to that of the clinical classification at a correlation coefficient of 0.87 (p<10-5). Conclusions: miRNome analyses suggest the primary involvement of skeletal muscle in SMA pathogenesis. The SMA-miRs are likely actively released in the blood flow; their function and target cells require to be elucidated. The accuracy of the SMA-score needs to be verified in replicative studies: if confirmed, its use could be crucial for the routine prognostic assessment, also in presymptomatic patients.

IgG4-Related Disease

Background The tendency of IgG4-related disease (IgG4-RD) to form pseudotumors, as well as its multisystemic nature, makes it the perfect mimicker of many conditions. Moreover, some clinical, serological, radiological, or histological features of the disease might be shared with some mimickers. Recently, 4 clinical phenotypes have been identified, and patients grouped in each phenotype have distinctive demographic, clinical, and serological features and outcomes, and, as expected, for each phenotype, a set of differential diagnoses should be considered. Summary of the Literature The main differential diagnoses for the pancreato-hepato-biliary phenotype are pancreatic adenocarcinoma and cholangiocarcinoma. Other differential diagnoses include type 2 autoimmune pancreatitis and primary sclerosing cholangitis. In patients with retroperitoneal/aortic phenotype, inflammatory conditions such as idiopathic retroperitoneal fibrosis and large vessel vasculitides should be ruled out, and most of the time, a biopsy will be needed to exclude malignancies. In head and neck limited phenotype, autoimmune conditions (eg, granulomatosis with polyangiitis, Graves orbitopathy, sarcoidosis), malignancies, and histiocytosis should be ruled out, whereas the main differential diagnoses of the Mikulicz/systemic phenotype are Sjögren syndrome, granulomatosis with polyangiitis, and multicentric Castleman disease. Conclusions Approaching a patient with probable IgG4-RD through a clinical phenotype framework will ease the diagnostic algorithm and facilitate the prompt recognition of the disease. There are certain clinical, serological, radiological, and histological features in each clinical phenotype that, if present, increase the likelihood that a patient may have IgG4-RD instead of the mimicker condition. Those clues that point toward IgG4-RD diagnosis should be actively sought in the workup of patients.
The effect of patient ethnicity on the accuracy of peripheral pulse oximetry in patients with COVID‐19 pneumonitis: a single‐centre, retrospective analysis

Pulse oximetry is used widely to titrate oxygen therapy and for triage in patients who are critically ill. However, there are concerns regarding the accuracy of pulse oximetry in patients with COVID‐19 pneumonitis and in patients who have a greater degree of skin pigmentation. We aimed to determine the impact of patient ethnicity on the accuracy of peripheral pulse oximetry in patients who were critically ill with COVID‐19 pneumonitis by conducting a retrospective observational study comparing paired measurements of arterial oxygen saturation measured by co‐oximetry on arterial blood gas analysis (SaO2) and the corresponding peripheral oxygenation saturation measured by pulse oximetry (SpO2). Bias was calculated as the mean difference between SaO2 and SpO2 measurements and limits of agreement were calculated as bias ±1.96 SD. Data from 194 patients (135 White ethnic origin, 34 Asian ethnic origin, 19 Black ethnic origin and 6 other ethnic origin) were analysed consisting of 6216 paired SaO2 and SpO2 measurements. Bias (limits of agreement) between SaO2 and SpO2 measurements was 0.05% (−2.21–2.30). Patient ethnicity did not alter this to a clinically significant degree: 0.28% (1.79–2.35), −0.33% (−2.47–2.35) and −0.75% (−3.47–1.97) for patients of White, Asian and Black ethnic origin, respectively. In patients with COVID‐19 pneumonitis, SpO2 measurements showed a level of agreement with SaO2 values that was in line with previous work, and this was not affected by patient ethnicity.
Males with low risk-taking propensity overestimate risk under acute psychological stress

Abstract Arousing research has investigated stressed individuals’ decision biases, but whether and how stress and individual traits interact to impact the underlying decision-making process is unknown. Here, we aim to explore the effect of acute stress on the interaction between the objective level of risk and subjective risk preference (i.e. risk-taking propensity). Eighty-three healthy males participated in the study. We adopted the Trier Social Stress Test (TSST) to induce acute psychological stress and categorized participants into the high or low risk-taking propensity (HRP/LRP) group according to their traits in daily life. The Balloon Analogue Risk Task (BART) was applied to measure their feedback processing in a risky decision task, while behavioral indexes and EEG signals were recorded. The results showed that stressful participants pumped fewer times than the controls, especially for the LRP under stress, indicating that they were more willing to avoid taking risks. Compared with the stressed HRP group, the stressed LRP showed higher salivary cortisol responses and a more positive FRN following positive feedback in higher risk levels. It implies that acute psychological stress leads the LRP to overestimate the risk probability and become more cautious in the sequential processing of risk. These findings highlight the role of the feedback process and individual traits in risky decision-making under stress.
Upregulation of miR-335 exerts protective effects against sepsis-induced myocardial injury

Septicemia is associated with excessive inflammation, oxidative stress and apoptosis, causing myocardial injury that results in high mortality and disability rates worldwide. The abnormal expression of multiple microRNAs (miRNAs/miRs) is associated with more severe sepsis-induced myocardial injury (SIMI) and miR-335 has been shown to protect cardiomyocytes from oxidative stress. The present study aimed to investigate the role of miR-335 in SIMI. An SIMI model was established by cecal ligation and puncture (CLP) in mice. An miRNA-335 precursor (pre-miR-335) was transfected to accelerate miR-335 expression and an miR-335 inhibitor (anti-miR-335) was used to inhibit miR-335 expression. CLP or sham surgery was performed on pre-miR-335, anti-miR-335 and wild-type mice and miR-335 expression was determined by reverse transcription-quantitative PCR. Inflammatory factors (TNF-α, IL-6 and IL-10) and troponin (cTNI), brain natriuretic peptide (BNP), creatine kinase (CK), lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) were assessed using commercial kits. Apoptosis was detected by flow cytometry and cardiac function was assessed using a Langendorff isolated cardiac perfusion system. miR-335 expression was upregulated and an elevation in inflammatory factors and cTNI, BNP, CK, LDH and AST was observed. Compared with the wild-type control group, pre-miR-335 mice treated with CLP exhibited significantly reduced left ventricular development pressure, maximum pressure increased reduction rates, as well as decreased levels of TNF-α, IL-6 and IL-10, myocardial injury and apoptosis; by contrast, these features were amplified in CLP-treated anti-miR-335 mice. In conclusion, the upregulation of miR-335 exerted ameliorative effects on myocardial injury following sepsis and may indicate a novel therapeutic intervention for SIMI.
Effect of the “Time to Surgery” on Civil Cranial Gunshot Injuries: Syria War

Abstract Studies on cranial gunshot injuries in the Syrian war are present in the literature. However, the effect of surgical timing on the clinical outcomes of patients undergoing surgical treatment has not been discussed extensively. In this study, the time from injury to surgery is called “time to surgery. ” Kilis, a city close to Aleppo, Afrin, and Azez, where the conflicts in Syria are intense, is one of the cities where the first emergency treatments were administered. This study aimed to evaluate patients who underwent surgery in Kilis State Hospital due to cranial gunshot injury in the Syrian war and to investigate the effect of surgical timing on mortality and Glasgow Outcome Score. Surgical treatment was applied to 42 (32.8%) patients in the first 4 hours, 64 (50%) patients within 4 to 24 hours, and 22 (17.2%) patients between 24 hours and 3 days. As the time to surgery decreased, the good Glasgow Outcome Score (GOS) (4-5) outcome rates increased. The differences in surgical timing and GOS results of patients with Glasgow Coma Score (GCS) <8 and >8 were found to be significant for good GOS results. As the time to surgery decreased for patients with a GCS <8 and >8, mortality rates decreased equally. This result was statistically significant. Our study showed that surgical timing is as important as early intubation, aggressive resuscitation, and admission GCS for both survey and GOS.
Antihypertensive and antihyperlipemic of spirulina (Arthrospira platensis) sauce on patients with hypertension: A randomized triple‐blind placebo‐controlled clinical trial

Systemic arterial hypertension is an independent risk factor for coronary heart disease, stroke, heart failure, and chronic kidney diseases. Spirulina is microalgae with nutritious ingredients and has potential attenuating effects on chronic diseases including hypertension. Spirulina can be added to food products in order to develop functional foods. The aim of this study was to assess the effects of 8‐week consumption of a salad dressing containing 2 g of spirulina platensis powder versus a placebo dressing on patients with hypertension. In this triple‐blind randomized clinical trial, 48 patients with hypertension were enrolled to receive daily either spirulina‐fortified dressing or placebo for 2 months. A total of 41 patients completed this study. We observed that the consumption of spirulina dressing significantly reduced systolic blood pressure (p = .02), diastolic blood pressure (p = .03), serum triglyceride (p = .01), total cholesterol, and low‐density lipoprotein (LDL) levels, compared to nonsignificant changes in the placebo group. Significant changes in TAC and hs‐CRP levels were observed in none of the groups. According to our findings, spirulina‐fortified dressing as a functional food can be used a supportive treatment for patients with hypertension along with standard antihypertensive drugs. However, further investigations are required for a more comprehensive conclusion.
The role of chemokines and adipokines as biomarkers of Crohn's disease activity: a systematic review of the literature.

INTRODUCTION Crohn's disease (CD) is an inflammatory bowel disease (IBD) that affects the gastrointestinal tract and can have a major impact on the patient's quality of life and social/professional activities. Asymptomatic patients, or those with mild symptoms, experience the active disease with subclinical manifestation. Systematic review (SR) was performed to look for evidence for the role of chemokines and adipokines as markers for CD activity. METHODS This SR was conducted by searching published studies in international and regional databases up till July, 2020. CD patients were adults with the disease in activity or remission. All adipokines and chemokines were considered for the analysis and the Rayyan QCRI system was used. RESULTS In total, 20 studies were included. Six addressed chemokines and eight adipokines as potential biomarkers of CD activity. CXCL8 was the most studied chemokine (8 studies) and the results were controversial, with 62.5% showing a significant association with CD activity. CXCL10 was investigated by 4 studies and 50% identified it as a potential biomarker. CCL2, CCL11, CCL26 and CXCL1 were examined by 2 articles each. CXCL8 (P=0.002/P=0.001) and CXCL1 (P<0.001) presented the lowest? P value, which qualifies them as potential markers of disease activity. All the adipokines were tested in peripheral blood but 44.4% were also tested in intestinal mucosa, while the percentage in the chemokines' studies was 76.9% in peripheral blood, 46.1% in intestinal mucosa and 7.6% in urine sample respectively. CONCLUSION The development of disease activity biomarkers for CD is becoming relevant for clinical practice. Chemokines and adipokines have the potential to signalize CD activity, but validation in larger cohorts of patients, preferable multicenter studies are still needed.
Analysis of the reliability of patient COVID-19 screening data compared against their actual test data

Objectives: This study aimed to evaluate the truthfulness of patients about their pre-appointment COVID-19 screening tests at a dental clinic. Methods: A total of 613 patients were recruited for the study from the dental clinic at the Faculty of Dentistry, Najran University, Saudi Arabia. The data collection was done in three parts from the patients who visited the hospital to receive dental treatment. The first part included the socio-demographic characteristics of the patients and the COVID-19 swab tests performed within the past 14 days. The second part was the clinical examination, and the third part was a confirmation of the swab test taken by the patient by checking the Hesen website using the patient ID. After data collection, statistical analysis was carried out using SPSS 26.0. Descriptive analysis was done and expressed as mean, standard deviation, frequency, and percentage (%). A cross-tabulation, also described as a contingency table, was used to identify trends and patterns across data and explain the correlation between different variables. Results: It was seen from the status of the swab test within 14 days of the patient's arrival at the hospital for the dental treatment that 18 (2.9%) patients lied about the pre-treatment swab test within 14 days, and 595 (97.1%) were truthful. The observed and expected counts showed across genders and diagnosis a statistically significant difference (p < 0.001), and there was no significant difference seen across different age groups (p = 0.064) of the patients. Conclusions: Dental healthcare workers are worried and assume a high risk of COVID-19 infection as the patients are not truthful about the pre-treatment COVID-19 swab test. Routine rapid tests on patients and the healthcare staff are a feasible option for lowering overall risks.
Widowed Young: The Role of Stressors and Protective Factors for Resilience in Coping with Spousal Loss

While distressing, late life spousal loss is considered a normative life event and most demonstrate resilient recovery from grief. However, for 5–7% of the population spousal loss comes early, before the age of 50, and little is known about the factors that influence adjustment in this population. We used the DPM integrative framework to examine correlates and predictors of mental wellbeing and grief intensity in an international sample of 603 young widows and widowers. Contrary to existing bereavement research, loss-orientated stressors (e.g., expectedness and cause of death) did not predict bereavement outcomes. Employment and financial wellbeing were the only statistically significant restoration-orientated stressors associated with coping, mental wellbeing and grief intensity. We found no significant associations between parental status and coping or bereavement outcomes. Loss-orientated coping, followed by inter and intrapersonal protective factors for resilience and financial wellbeing were the greatest predictors of grief intensity. Loss-orientated coping was highest in early bereavement, the greatest predictor of grief intensity and associated with being unemployed, financial insecurity and decreased protective factors for resilience. Restoration-orientated coping was highest in later bereavement, was a weak predictor of grief intensity and associated with being employed, increased financial wellbeing and protective factors for resilience. Overall, we found the young-widowed population is at heightened risk of poor adjustment. Almost two-thirds reported decreased functioning, probable depression with high rates of psychological distress. Nearly half met diagnostic criteria for prolonged grief disorder. We discuss implications for research and clinical practice.
