BackgroundDiagnosis of asthma and chronic obstructive pulmonary disease (COPD) in the community is variable, often without spirometry. Some studies report that adults with both diagnostic labels (asthma+COPD) have worse health outcomes than those with asthma or COPD only, but data for Australian adults are limited. We investigated the relationship between clinical characteristics and self-reported diagnoses of asthma, COPD and both.MethodWe used data from the BOLD Australia study, which included randomly selected adults aged ≥40 years from six study sites. The BOLD questionnaires and spirometry test were used in all sites. Participants were grouped by self-reported diagnosis. Demographic and clinical characteristics and lung function were compared between groups.ResultsOf the study sample (n=3522), 336 reported asthma only, 172 reported COPD only, 77 reported asthma+COPD and 2937 reported neither. Fewer than half of participants with a COPD diagnosis (with or without asthma) had airflow limitation. Participants with asthma+COPD had more respiratory symptoms and greater airflow limitation than those with either diagnosis alone. Having asthma+COPD was independently associated with a higher probability of having clinically important breathlessness (modified Medical Research Council score ≥2) than asthma only (adjusted OR 3.44, 95% CI 1.86–6.33) or COPD only (adjusted OR 3.28, 95% CI 1.69–6.39). Airflow limitation (Global Initiative for Chronic Obstructive Lung Disease 2 or higher, using post-bronchodilator forced expiratory volume in 1 s/forced vital capacity ratio <0.7) was similar between asthma only and COPD only, but twice as prevalent in asthma+COPD (adjusted OR 2.18 and 2.58, respectively).ConclusionsAdults with diagnoses of asthma+COPD have a higher symptom and disease burden than those with diagnoses of asthma only or COPD only. These patients should receive regular comprehensive reviews because of the substantially increased burden of having both diagnoses.

BackgroundProne positioning is routinely used among patients with COVID-19 requiring mechanical ventilation. However, its utility among spontaneously breathing patients is still debated.MethodsIn an open-label randomised controlled trial, we enrolled patients hospitalised with mild COVID-19 pneumonia, whose arterial oxygen tension to inspiratory oxygen fraction ratio (PaO2/FIO2) was >200 mmHg and who did not require mechanical ventilation or continuous positive airway pressure at hospital admission. Patients were randomised 1:1 to prone positioning on top of standard of care (intervention group)versusstandard of care only (controls). The primary composite outcome included death, mechanical ventilation, continuous positive airway pressure andPaO2/FIO2<200 mmHg; secondary outcomes were oxygen weaning and hospital discharge.ResultsA total of 61 subjects were enrolled, 29 adjudicated to prone positioning and 32 to the control group. By day 28, 24 out of 61 patients (39.3%) met the primary outcome: 16 because of aPaO2/FIO2ratio <200 mmHg, five because of the need for continuous positive airway pressure and three because of the need for mechanical ventilation. Three patients died. Using an intention-to-treat approach, 15 out of 29 patients in the prone positioning groupversusnine out of 32 controls met the primary outcome, corresponding to a significantly higher risk of progression among those randomised to prone positioning (HR 2.38, 95% CI 1.04–5.43; p=0.040). Using an as-treated approach, which included in the intervention group only patients who maintained prone positioning for ≥3 h·day−1, no significant differences were found between the two groups (HR 1.77, 95% CI 0.79–3.94; p=0.165). Also, we did not find any statistically significant difference in terms of time to oxygen weaning or hospital discharge between study arms in any of the analyses conducted.ConclusionsWe observed no clinical benefit from prone positioning among spontaneously breathing patients with COVID-19 pneumonia requiring conventional oxygen therapy.

Abstract
Background
Hepatorenal syndrome (HRS) is a life-threatening complication of end-stage liver disease. This study aimed to clarify the status of HRS in Japan by analyzing the Japanese Diagnosis Procedure Combination database.

Methods
Patients hospitalized for cirrhosis and HRS from July 2010 to March 2019 were sampled. They were divided into two groups according to their prognosis upon discharge: the transplant-free survival group and the death or liver transplantation group. The two groups’ baseline patient characteristics and treatments were compared.

Results
The mean age of the 1,412 participants was 67.3 years (standard deviation: 12.3 years), and 65.4% were male. The Child–Pugh grades was B and C in 18.8% and 81.2%, respectively. Hepatocellular carcinoma was present in 27.1% of the patients, and the proportion of spontaneous bacterial peritonitis was 2.3%. Albumin, noradrenaline, and dopamine were administered to 57.9%, 8.0%, and 14.9% of the patients, respectively; 7.0% of the patients underwent renal replacement therapy; and 5.0% were admitted to the intensive care unit. Intravenous antibiotics were administered to 30.8% of the patients. A total of 925 patients (65.5%) died or underwent liver transplantation. In addition to a higher proportion of patients with poor baseline liver function, the death or liver transplantation group included more males, patients with hepatocellular carcinoma, and those with spontaneous bacterial peritonitis.

Conclusions
HRS in Japan has a high mortality rate. Albumin was administered to over 50% of participants. Although noradrenaline is recommended in Japanese clinical guidelines, dopamine was more frequently used as a vasoconstrictor in clinical practice.

Published: June 2023

Background
Prolonged second stage of labour has been associated with adverse maternal and perinatal outcomes. The maximum length of the second stage from full dilatation to birth of the baby remains controversial. Our aim was to determine whether extending second stage of labour was associated with adverse maternal and perinatal outcomes.

Methods
A retrospective cohort study was conducted using routinely collected hospital data from 51592 births in Aberdeen Maternity Hospital between 2000 and 2016. The hospital followed the local guidance of allowing second stage of labour to extend by an hour compared to national guidelines since 2008 (nulliparous and parous). The increasing duration of second stage of labour was the exposure. Baseline characteristics, maternal and perinatal outcomes were compared between women who had a second stage labour of (a) ≤ 3 h and (b) > 3 h duration for nulliparous women; and (a) ≤ 2 h or (b) > 2 h for parous women. An additional model was run that treated the duration of second stage of labour as a continuous variable (measured in hours). All the adjusted models accounted for: age, BMI, smoking status, deprivation category, induced birth, epidural, oxytocin, gestational age, baby birthweight, mode of birth and parity (only for the final model).

Results
Each hourly increase in the second stage of labour was associated with an increased risk of obstetric anal sphincter injury (aOR 1.21 95% CI 1.16,1.25), having an episiotomy (aOR 1.48 95% CI 1.45, 1.52) and postpartum haemorrhage (aOR 1.27 95% CI 1.25, 1.30). The rates of caesarean and forceps delivery also increased when second stage duration increased (aOR 2.60 95% CI 2.50, 2.70, and aOR 2.44 95% CI 2.38, 2.51, respectively.) Overall adverse perinatal outcomes were not found to change significantly with duration of second stage on multivariate analysis.

Conclusions
As the duration of second stage of labour increased each hour, the risk of obstetric anal sphincter injuries, episiotomies and PPH increases significantly. Women were over 2 times more likely to have a forceps or caesarean birth. The association between adverse perinatal outcomes and the duration of second stage of labour was less convincing in this study.

Abstract
Background
Prenatal posttraumatic stress symptoms (PTSS), fear of childbirth (FOC), and depressive symptoms have been related to various negative effects during pregnancy, childbirth, and in the postnatal period. This study evaluates the prevalence of PTSS, FOC, depressive symptoms, and health-related quality of life (HRQoL) among pregnant women, their partners, and as couples.

Methods
In a cohort of 3853 volunteered, unselected women at the mean of 17th weeks of pregnancy with 3020 partners, PTSS was evaluated by Impact of Event Scale (IES), FOC by Wijma Delivery Expectancy Questionnaire (W-DEQ-A), depressive symptoms by Edinburgh Postnatal Depression Scale (EPDS), and HRQoL by 15D instrument.

Results
PTSS (IES score ≥ 33) was identified among 20.2% of the women, 13.4% of the partners, and 3.4% of the couples. Altogether, 5.9% of the women, but only 0.3% of the partners, and 0.04% of the couples experienced symptoms suggestive of phobic FOC (W-DEQ A ≥ 100). Respectively, 7.6% of the women, 1.8% of the partners, and 0.4% of the couples reported depressive symptoms (EPDS ≥ 13). Nulliparous women and partners without previous children experienced FOC more often than those with previous children, but there was no difference in PTSS, depressive symptoms, or HRQoL. Women’s mean 15D score was lower than partners’ and that of age- and gender-standardized general population, while partners’ mean 15D score was higher than that of age- and gender-standardized general population. Women whose partners reported PTSS, phobic FOC, or depressive symptoms, often had the same symptoms (22.3%, 14.3%, and 20.4%, respectively).

Conclusions
PTSS were common in both women and partners, as well as in couples. FOC and depressive symptoms were common in women but uncommon in partners, thus they rarely occurred simultaneously in couples. However, special attention should be paid to a pregnant woman whose partner experiences any of these symptoms.

Abstract
Background
As the population ages, chronic non-communicable diseases (NCDs) multimorbidity has emerged as a major public health issue globally. This study examines ethnic disparities in prevalence of NCDs and its multimorbidity among rural southwest Chinese older adults.

Methods
A cross-sectional survey was conducted in rural southwest population aged ≥ 60 years consisting of 5,642 consenting participants of Han and three ethnic minority groups (Dai, Ha Ni, and Bai). Information about participants’ demographic characteristics and lifestyle behaviors was obtained using a standard questionnaire. Anthropometric measurements including height, weight, and waist circumference, fasting blood sugar and blood pressure measurement, as well as post-bronchodilator spirometry test were recorded for each participant.

Results
The age-standardized prevalence of five common chronic NCDs– hypertension, diabetes, coronary heart disease (CHD), stroke, chronic obstructive pulmonary disease (COPD) – and its multimorbidity was 72.8%, 15.9%, 4.0%, 10.0%, 9.8%, and 27.6%, respectively. Bai participants had both the highest overall and sex-specific prevalence rates of hypertension, diabetes, stroke, and COPD, whereas Han participants had the highest rates of CHD (P < 0.01). The results of multivariate logistic regression analysis indicated that female and older participants had a higher probability of chronic NCDs multimorbidity than their counterparts (P < 0.01). Bai ethnic minority participants were more likely to have NCDs multimorbidity while Ha Ni and Dai ethnic minority participants were less likely to have NCD multimorbidity relative to the Han participants (P < 0.05). Older adults with a higher level of education and family history of chronic NCDs, and who were also current smokers, current drinkers, obese, centrally obese, and physically inactive had a greater probability of developing chronic NCDs multimorbidity (P < 0.01).

Conclusions
Ethnicity and individual demographic and lifestyle factors significantly impact prevalence of chronic NCDs multimorbidity. Future chronic NCDs prevention and control strategies must be tailored to address ethnicity, and culturally tailored lifestyle interventions may reduce the prevalence of chronic NCDs multimorbidity in rural southwest China.

Abstract
Background
Feedback is regarded as a key component of formative assessment and one of the elements with the greatest impact on students’ academic learning. The present study aimed to evaluate and compare students’ perceptions of the use of two feedback models, namely feedback sandwich and Ask-Tell-Ask (ATA), in teaching dental materials science courses.

Methods
All undergraduate second-year dental students were invited to participate in the dental materials science practical session and were randomly allocated into two groups: Group 1 (feedback) sandwich and Group 2 (ATA). The session began with the teacher giving a short briefing on the commonly used dental materials, followed by a short demonstration of the manipulation of those materials. Students were then allowed to mix and manipulate the materials, and teachers provided feedback accordingly. At the end of the session, 16 close-ended (five-point Likert scales) and an open-ended questionnaire were distributed to students to evaluate their perceptions of the feedback given. Internal reliability of the questionnaire items was evaluated using Cronbach’s alpha. Mean feedback scores were analysed using an independent t-test with ANCOVA for controlling gender and ethnicity. Thematic analysis was used to code the qualitative data.

Results
Sixty-nine students participated in the present study with the majority being females (72.5%) and Chinese (79.7%). Cronbach’s alpha analysis suggested removing three Likert-scale items, with the remaining 13 items being accepted. Generally, no significant difference was noted between the two groups (p = 0.197), but three items were found to be significant (p < 0.05), with higher mean scores in the feedback sandwich group. Moreover, no significant difference was noted between the two feedback models (p = 0.325) when controlling gender and ethnicity. The open-ended question showed that students in the feedback sandwich group expressed greater positive perceptions.

Conclusion
Although students generally had positive perceptions of both feedback models, they tended to favour the feedback sandwich. Neither gender nor ethnicity affected the students’ perceptions of the two feedback models.

Abstract
Background
Low adherence to triage after positive screening is a widespread problem for cervical cancer screening programs in Low- and Middle-income Countries. Adherence to cytology-based triage can be challenging, especially among women with self-collected tests. SMS-based interventions are accepted by women and can increase screening uptake. The ATICA study was an effectiveness-implementation hybrid type I trial, combining a cluster randomized controlled trial (RCT) with a mixed-methods implementation evaluation involving quantitative and qualitative methods. Although the RCT provided evidence regarding the effectiveness of the SMS-based intervention, less is known about its acceptability, relevance, and usefulness from the women´s perspective.

Methods
We carried out a cross-sectional study based on a structured questionnaire among HPV-positive women who were enrolled in ATICA's intervention group. We measured acceptability, appropriateness, and message content comprehension. Also, we evaluated if the SMS message was considered a cue to encourage women to pick up their HPV test results and promote the triage.

Results
We interviewed 370 HPV-positive women. Acceptability of SMS messages among women who had received at least one message was high (97%). We found high levels of agreement in all appropriateness dimensions. More than 77% of women showed high comprehension of the content. Among women who received at least one SMS message, 76% went to the health center to pick up their results. Among those who got their results, 90% reported that the SMS message had influenced them to go. We found no significant differences in acceptability, appropriateness or message comprehension between women who adhered to triage and those who did not adhere after receiving the SMS messages.

Conclusion
The intervention was highly acceptable, and women reported SMS was an appropriate channel to be informed about HPV test results availability. SMS was also a useful cue to go to the health center to pick up results. The implementation did not encounter barriers associated with the SMS message itself, suggesting the existence of other obstacles to triage adherence. Our results support the RCT findings that scaling up SMS is a highly acceptable intervention to promote cervical screening triage adherence.

Abstract
Background
Uterine clear cell carcinomas (CCC) represent less than 5% of uterine cancers. Their biological characteristics and clinical management remain uncertain. A multicenter study to explore both clinical and molecular features of these rare tumors was conducted.

Methods
This multicenter retrospective national study was performed within the French TMRG (Rare Gynecologic Malignant Tumors) network. Clinical data and, when available, FFPE blocks were collected. Clinical features, treatments, and outcome (progression-free survival (PFS) and overall survival (OS)) were analyzed and correlated to the protein (tissue micro-array), RNA (Nanostring nCounter® technology), and DNA (array-Comparative Genomic hybridization and target-next generation sequencing) levels using the tumor samples available.

Results
Sixty-eight patients with uterine CCC were enrolled, 61 from endometrial localization and 5 with cervix localization. Median age at diagnosis was 68.9 years old (range 19–89.7). Most tumors were diagnosed at an early stage (78% FIGO stage I–II). Hysterectomy (performed in 90%) and lymph node dissection (80%) were the most frequent surgical treatment. More than 70% of patients received external beam radiotherapy and 57% received brachytherapy. Nearly half (46%) of the patients received chemotherapy. After a median follow-up of 24.7 months, median PFS was 64.8 months (95 CI [5.3–124.4]) and median OS was 79.7 (IC95 [31.0–128.4]). Low hormone receptor expression (13% estrogen-receptor positive), frequent PI3K pathway alterations (58% PTEN loss, 50% PIK3CA mutations), and P53 abnormalities (41%) were observed. Mismatch repair deficiency was identified in 20%. P16 expression was associated with shorter PFS (HR = 5.88, 95 CI [1.56–25], p = 0.009). Transcriptomic analyzes revealed a specific transcriptomic profile notably with a high expression of immune response-associated genes in uterine CCC displaying a very good overall prognosis.

Conclusions
Uterine CCC reported to be potentially MSI high, hormone receptors negative, and sometimes TP53 mutated. However, some patients with immune response-associated features and better prognosis may be candidate to treatment de-escalation and immunotherapy.
