ABSTRACT

A profile mixture (PM) model is a model of protein evolution, describing sequence data in which sites are assumed to follow many related substitution processes on a single evolutionary tree. The processes depend, in part, on different amino acid distributions, or profiles, varying over sites in aligned sequences. A fundamental question for any stochastic model, which must be answered positively to justify model-based inference, is whether the parameters are identifiable from the probability distribution they determine. Here, using algebraic methods, we show that a PM model has identifiable parameters under circumstances in which it is likely to be used for empirical analyses. In particular, for a tree relating 9 or more taxa, both the tree topology and all numerical parameters are generically identifiable when the number of profiles is less than 74.

ABSTRACT

Dupilumab is a monoclonal antibody against the IL-4 receptor alpha which has shown efficacy in T2 high severe asthmatics in phase 3 randomized controlled trials. The purpose of this real-life study is to demonstrate the real-life effectiveness of dupilumab in Austrian severe asthma patients. We retrospectively analyzed all patients receiving dupilumab at our severe asthma clinic. Thirteen patients have so far received dupilumab at our center. The primary outcome, asthma control questionnaire 6-item scale at 2 weeks, improved by 0.57 points (p = .014), which is statistically and clinically significant. Similarly, the asthma control test at 4 weeks improved by 3.91 points (p = .024), also statistically and clinically significant. Improvements in forced expiratory volume in 1 s at 2 weeks were neither statistically, nor clinically significant. Improvements at 4 weeks (+220 ml, p = .041), and 3 months (+229 ml, p = .006), were statistically significant and clinically borderline significant. No severe adverse events or hypereosinophilia were observed. No adverse events led to treatment discontinuation. Most patients (85%) had previously received monoclonal antibody treatment for severe asthma. Previous monoclonal antibody treatment had been discontinued in these patients due to a lack of clinical response. Dupilumab is effective and safe in Austrian real-life severe asthmatics. It provides a possible treatment strategy for T2 high severe asthmatics who do not qualify for anti-immunoglobulin E or anti-IL5/IL5R monoclonal antibody treatments or do not adequately respond to these.

ABSTRACT

BACKGROUND: A discussion about patient’s nonmedical needs during treatment is considered a crucial component of high-quality patient-provider communication. We examined whether having a patient-provider discussion about cancer patients’ emotional and social needs is associated with their psychological well-being.

METHODS: Using the 2016-2017 Medical Expenditure Panel Survey-Experiences with Cancer Survivorship Supplement (MEPS-ECSS) data, we identified the cancer survivors in the United States (US) who reported having a detailed discussion about emotional and social needs during cancer care. We used multivariable logistic regression to assess the association between having a patient-provider discussion and the patients’ psychological well-being outcomes (depressive symptoms, severe psychological distress, and worrying about cancer recurrence/worsening condition) and benefit finding experience after a cancer diagnosis.

RESULTS: Among 1433 respondents (equivalent to 13.8 million cancer survivors in the US), only 33.6% reported having a detailed patient-provider discussion about their emotional and social needs. Having a discussion was associated with 55% lower odds (odds ratio [OR], 0.45; 95% confidence interval [CI], 0.26-0.77) of having depressive symptoms and 97% higher odds (OR, 1.97; 95% CI, 1.46-2.66) of having benefit finding experience. There was no statistically significant association between patient-provider discussion and psychological distress or worrying about cancer recurrence/worsening.

CONCLUSION: Detailed patient-provider discussion about the cancer patients’ emotional and social needs was associated with a lower likelihood of depressive symptoms and a higher likelihood of experiencing benefit finding. These findings stress the importance of improving the patient-provider discussion about psychosocial needs in cancer survivorship.

ABSTRACT

BACKGROUND: During the recent COVID-19 outbreak, masks became mandatory and shortages frequent, therefore the prevalence of non-CE (European Conformity Mark) approved masks increased in the general population. We aimed to quantify the prevalence of mask-related cutaneous side effects and the differences between CE and non-CE approved masks.

METHODS: In this multicenter prospective observational study conducted from March 20, 2020 to May 12, 2020(during and after quarantine), patients attending emergency departments for a dermatological consult were clinically assessed and their masks were inspected to detect CE marks and UNI (Italian National Unification Entity) norms. Patients with history of facial dermatoses or under current treatment for facial dermatoses were excluded.

RESULTS: We enrolled 412 patients (318 during quarantine and 94 after quarantine). CE-approved masks were observed 52.8% vs. 24.5%, whilst subsets of non-CE approved masks were 9.7% vs. 14.9% (Personal protective equipment (PPE)-masks), 16.4% vs. 12.8% (surgical masks [SM]), and 21.1% vs. 47.9%(non-PPE) and (non-SM masks), respectively during and after quarantine. Remarkably, non-CE-approved masks resulted in patients displaying a statistically significant higher incidence of facial dermatoses and irritant contact dermatitis compared to CE-approved masks, and these differences were mainly driven by non-PPE non-SM masks. Comparing quarantine and after quarantine periods, no statistically significant differences were found for CE-approved masks, whilst differences were detected in non-CE-approved masks regarding incidence of facial dermatoses (P<0.0001)and irritant contact dermatitis (P=0.0041).

CONCLUSIONS: Masks are essential to prevent COVID-19 but at the same time higher awareness regarding mask specifications should be promoted in the general population. Non-PPE and non-SM masks should undergo more rigorous testing to prevent the occurrence of cutaneous side effects and future patients’ lawsuit damages.

ABSTRACT

Skin cleansers and protectants protect skin from incontinent matter to reduce the risk of incontinence-associated dermatitis (IAD), but their effectiveness treating established IAD in the tropics is unknown. We conducted an open-label cluster randomised trial to compare the effectiveness of a combined regimen of (1) specialised skin cleansers with disposable body wipes and (2) either an acrylic terpolymer (T1) or zinc oxide (T2) skin protectant against disposable body wipes and zinc oxide protectant (control) in promoting IAD healing and reducing the risk of deterioration. Eighty-four patients were recruited in a tertiary hospital in Singapore between April 2019 and January 2020 (T1: n = 23; T2: n = 37; Control: n = 24). Although not statistically significant, patients treated with T1 and T2 were 1.5 times as likely to experience IAD healing within seven days compared with the control (P = .66). Healing was more pronounced in participants with skin loss treated with T1 or T2. No treatment was superior in preventing IAD deterioration, the prevalence of which remained small (8%-14%). While skin cleaning and protectants reduced the overall risk of skin deterioration, the addition of skin cleansers enhanced IAD healing within a short period, an important consideration for future research examining IAD treatment in acute care.

ABSTRACT

Undernutrition is linked to almost half of all deaths in under-five children. In 2019, 144 million under-five children suffered from stunting and 47 million suffered from wasting. This study examined the factors that influence adverse nutritional status of children in sub-Saharan Africa. The study used data from the Demographic and Health Surveys (DHS) of 31 countries, which involved 189,195 children under age 5. Binary logistic regression was used to examine the relationships between the independent variables and adverse nutritional status of children. About 26% of the children in the 31 countries in sub-Saharan Africa considered in this study are stunted, 6% are wasted and 21% are underweight. Close to 31% of children whose mothers have no education are stunted, 9% are wasted and 28% are underweight. Adverse nutritional status of children is significantly associated with maternal age, education, household wealth, residence, antenatal care attendance, mass media exposure, child’s sex and size of child at birth. This study has shown that adverse nutritional status of children is a major challenge in sub-Saharan Africa. Efforts at improving nutritional status of children should include poverty alleviation initiatives at individual and household levels, increase in women’s educational level and improvement in living conditions in rural areas.

ABSTRACT

OBJECTIVE: To evaluate the effects of early ambulation on elderly patients’ postoperative physical functional outcomes, complications, 90-day readmission rate, and the length of postoperative hospital stay.

METHODS: This is a prospective cohort study conducted between June 2019 and December 2019. The study enrolled 86 elderly patients (39 males) with newly diagnosed lumbar degenerative disease undergoing single-segment decompression and fusion surgerywere enrolled. Of all 86 patients, 39 voluntarily joined the early ambulation group, and 47 joined the regular ambulation group. The early ambulation group included patients ambulated within 4 h postoperatively, whereas the regular ambulation group included patients who were ambulatory at a minimum of 24 h after surgery. Participants’ baseline characteristics, surgical information, ambulation ability, degree of pain, functional scores, postoperative complications, 90-day readmission rate, and length of postoperative hospital stay were recorded.

RESULTS: Participants’ baseline demographic characteristics were balanced between the early ambulation group and the regular ambulation group. The operative time and blood loss were similar between groups. The time before the first-time ambulation was 4 ± 0.5 h in the early ambulation group and 28 ± 4.5 h in the regular ambulation group. Ambulating distance was significantly longer in the early ambulation group compared with the regular ambulation group on the 1st (63 ± 45 vs 23 ± 60 m), the 2nd (224 ± 100 vs 101 ± 130 m), and the 3rd (280 ± 102.5 vs 190 ± 170 m) ambulation days based on generalized estimating equation analyses. Generalized estimating equation analyses also demonstrated that the ambulating time was longer in the early ambulation group compared with the regular ambulation group on the 1st (10 ± 5 vs 10 ± 5 min), the 2nd (19 ± 7 vs 15 ± 5 min), and the 3rd (22 ± 16.5 vs 27 ± 12 min) ambulation days. Patients in the regular ambulation group experienced a higher degree of pain than the early ambulation group patients, with an odds ratio of 1.627 (P = 0.002). Short-term functional independence was superior in the early ambulation group, with a lower Roland-Morris disability questionnaire score (P = 0.008) and Oswestry disability index (P < 0.001). The incidences of postoperative urinary retention (early ambulation group: 7.7%, regular ambulation group: 25.5%, P = 0.030) and ileus (early ambulation group: 0%, regular ambulation group: 12.8%, P = 0.030) were significantly higher in the regular ambulation group. The prevalence of at least one complication rate was significantly lower in the early ambulation group than in the regular ambulation group (early ambulation group, 23.1%; regular ambulation group, 46.8%, P = 0.022). The duration of indwelling of the drainage catheter was shorter in the early ambulation group (early ambulation group, 68 ± 24 h; regular ambulation group, 78 ± 20 h, P = 0.001), and the length of the postoperative hospital stay was also shorter in the early ambulation group (early ambulation group, 4 ± 0 days; regular ambulation group: 5 ± 2 days, P < 0.001). However, there was no statistical difference in the 90-day readmission rate between groups.

CONCLUSION: Early ambulation improved patients’ postoperative functional status, decreased the incidence of complications, and shortened postoperative hospital stay in elderly patients undergoing lumbar decompression and fusion surgery.

ABSTRACT

INTRODUCTION: Myanmar is a Low-Middle Income Country (LMIC) in South-East Asia. Over the last decade, reforms to the health system have included significant improvements in the delivery of radiation therapy services in both government and private-for-profit sectors.

METHODS: This review uses limited cancer registry data, observations from in-person visits, and data from key informants in Myanmar radiation therapy centres, to report on developments in radiation therapy services in recent years.

RESULTS: Rising national cancer incidence estimates presented in this article are supplemented with annual cancer case and radiation therapy course completion statistics from three hospital / regional contexts. Strategies which enabled the increased delivery of radiation therapy services are described. Data regarding the geographic locations of radiation therapy centres, their equipment and software inventories, is tabulated. The impact on clinical practice standards through upgraded equipment and software used for treatment planning and delivery is discussed. Clinical staffing at each centre is catalogued, role descriptions are given, and increases in staff numbers in recent years are documented. The present clinical and academic education challenges for radiation therapy staff and the importance of these issues for technical practice advancements are discussed.

CONCLUSION: Myanmar’s successes and continued challenges in radiation therapy service delivery are emulated in other LMIC’s. Strategic planning for new and existing radiation therapy centres, further staff increases and improved academic and clinical learning for radiation therapy staff should assist in meeting these challenges. Further international engagement could also enhance these processes.

ABSTRACT

The gene coding interleukin 6 (IL-6) is a promising candidate in predisposition to type 2 diabetes mellitus (T2DM). This study aimed to meta-analytically examine the association of IL-6 gene -174G/C polymorphism with T2DM and circulating IL-6 changes across -174G/C genotypes. Odds ratio (OR) and standard mean difference (SMD) with 95% confidence interval (CI) were calculated. Twenty-five articles were meta-analysed, with 20 articles for T2DM risk and 9 articles for circulating IL-6 changes. Overall, there was no detectable significance for the association between -174G/C polymorphism and T2DM, and this association was relatively obvious under dominant model (OR: 0.82, 95% CI: 0.56-1.21). Improved heterogeneity was seen in some subgroups, with statistical significance found in studies involving subjects of mixed races (OR: 0.63, 95% CI: 0.46-0.86). Begg’s and filled funnel plots, along with Egger’s tests revealed week evidence of publication bias. In genotype-phenotype analyses, carriers of -174CC and -174CG genotypes separately had 0.10 and 0.03 lower concentrations (pg/mL) of circulating IL-6 than -174GG carriers. Albeit no detectable significance for the association of -174G/C with T2DM, our findings provided suggestive evidence on a dose-dependent relation between -174G/C mutant alleles and circulating IL-6 concentrations, indicating possible implication of this polymorphism in the pathogenesis of T2DM.

ABSTRACT

OBJECTIVE: To assess the utility of the neutrophil-to-lymphocyte ratio (NLR) in predicting outcome in canine pneumonia compared with routine hematological parameters and systemic inflammatory response syndrome (SIRS) scores.

DESIGN: Retrospective study.

SETTING: University teaching hospital.

ANIMALS: Forty-nine client-owned dogs.

INTERVENTIONS: None MEASUREMENTS AND MAIN RESULTS: Medical records were reviewed to identify dogs with a diagnosis of pneumonia from July 2011 to December 2016. Signalment, clinical findings, laboratory characteristics, and outcome were recorded. Inclusion criteria were a clinical and radiographic diagnosis of pneumonia, plus reference laboratory hematology at diagnosis. Cases that received steroids were excluded. Euthanized dogs were only included in statistical analysis if euthanized solely due to pneumonia severity. The NLR, total WBC count, neutrophil count, lymphocyte count, band neutrophil percent of total WBC count (%-bands), and percentage of cases diagnosed with SIRS were compared between survivors and nonsurvivors. Receiver operating characteristic curves were generated to identify optimal sensitivity and specificity cutoffs for nonsurvival to discharge. Two hundred records were retrieved; 49 cases fulfilled the inclusion criteria. Of these, 33 (67%) survived to discharge. The NLR did not differ significantly between the survivors and nonsurvivors, nor did total WBC count or neutrophil count. Survivors had a significantly lower %-bands than nonsurvivors (P < 0.001) and higher lymphocyte count (P = 0.004). The mortality rate did not differ significantly between dogs with and without SIRS. Receiver operating characteristic analysis identified a %-bands cutoff of 2.5% or higher had an 83% sensitivity and 79% specificity for nonsurvival.

CONCLUSIONS: Unlike in human medicine, neither NLR nor SIRS scores predicted outcome in this cohort of dogs with pneumonia. However, survivors had a lower %-bands and higher lymphocyte count than nonsurvivors, which may be helpful prognostically in clinical cases.
