Effects of the COVID-19 Pandemic and Telehealth on Antenatal Screening and Services, Including for Mental Health and Domestic Violence: An Australian Mixed-Methods Study.

Introduction: Australian antenatal care includes specific screening and service provision for domestic and family violence (DFV) and mental health. However, the COVID-19 pandemic resulted in major care changes, including greatly expanded telehealth. Given difficulties in a safe assessment and management of disclosures via telehealth, DFV and mental health service provision might be substantially impacted. This study therefore aimed to assess COVID-19 effects on DFV and mental health screening, as well as broader service provision from the perspective of local maternity service providers. Methods: Mixed-methods study of staff surveys and interviews of staff directly involved in pregnancy care (doctors, midwives, and allied health) in three Sydney (Australia) maternity units, from October 2020 to March 2021. Surveys and interviews interrogated perceived effects of the COVID-19 pandemic on delivery (ensuring required services occurred), timeliness, and quality of (a) overall maternity care and (b) DFV and mental health screening and care; and also advantages and disadvantages of telehealth. Surveys were descriptively analyzed. Interviews were conducted online, recorded, and transcribed verbatim prior to thematic analysis. Results: In total, 17 interviews were conducted and 109 survey responses were received. Breakdown of survey respondents was 67% of midwives, 21% of doctors, and 10% of allied health. Over half of survey respondents felt the pandemic had a negative effect on delivery, timeliness, and quality of overall pregnancy care, and DFV and mental health screening and management. Perceived telehealth positives included convenience for women (73%) and reducing women's travel times (69%). Negative features included no physical examination (90%), difficulty regarding non-verbal cues (84%), difficulty if interpreter required (71%), and unsure if safe to ask some questions (62%). About 50% felt telehealth should continue post-pandemic, but for <25% of visits. Those perceived suitable for telehealth were low-risk and multiparous women, whereas those unsuited were high-risk pregnancy, non-English speaking, and/or mental health/psychosocial/DFV concerns. "Change to delivery of care" was the central interview theme, with subthemes of impact on mental health/DFV screening, telehealth (both positive and negative), staff impact (e.g., continuity of care disruption), and perceived impact on women and partners. Discussion: While telehealth may have an ongoing, post-pandemic role in Australian maternity care, staff believe that this should be limited in scope, mostly for low-risk pregnancies. Women with high risk due to physical health or mental health, DFV, and/or other social concerns were considered unsuited to telehealth.

Effect of MyTeen SMS-Based Mobile Intervention for Parents of Adolescents: A Randomized Clinical Trial.

Importance: There is global pressure to respond to the burden posed by adolescent mental health problems. The National Mental Health Commission has made a call for investment in mobile health services directed at prevention and early intervention to relieve the demand on targeted mental health services that are costly to provide. Parents and primary caregivers play a significant role in the lives of adolescents and are important targets for such efforts. Currently, there is no evidence for the effectiveness of programs delivered solely via text message for parents of adolescents. Objective: To evaluate the effects of a text-messaging program (MyTeen) on promoting parental competence and mental health literacy for parents of adolescents. Design, setting, and participants: A parallel 2-group randomized clinical trial was conducted in New Zealand. A total of 221 parents and primary caregivers of adolescents aged 10 to 15 years were recruited from March 19 to August 17, 2018, via community outreach and social media and were randomly allocated 1:1 into the control or the intervention group. Statistical analysis was performed on the principle of intention to treat with adjustment for baseline factors and ethnicity. Intervention: A text-messaging program for parents of adolescents (age 10-15 years) to promote parental competence and mental health literacy. Participants received 1 daily text message over 4 weeks. Main outcomes and measures: Parental competence, assessed at 1 month after randomization by the Parenting Sense of Competence Scale. Results: In total, 221 participants (214 [96.8%] female) were randomized, 109 to the intervention group and 112 to the control group; 201 participants (91%) completed the trial at 3 months. Significant group difference was observed on the primary outcome at the end of 1 month of intervention, with participants reporting a higher level of parental competence than those in the control group (estimated mean difference, 3.33 points; 95% CI, 1.37-5.29 points; P = .002). Except for knowledge about mental health, all secondary outcomes were significant, including continued improvement in parental competence at 3 months (estimated mean difference, 4.08 points; 95% CI, 1.96-6.20 points; P < .001), knowledge of help seeking (estimated mean difference, 0.99 points; 95% CI, 0.49-1.50 points; P < .001), parental distress (estimated mean difference, -2.39 points; 95% CI, -4.37 to -0.40 points; P = .02), and parent-adolescent communication (estimated mean difference, 2.21 points; 95% CI, 0.48-3.95 points; P = .01), with participants in the intervention group reporting better parenting-related outcomes than the control group at 1 and 3 months after the intervention. Conclusions and relevance: This text-messaging program for parents of adolescents appears to be an effective and feasible way to facilitate the implementation and delivery of evidence-based information to populations that are not easily reached with other intervention modalities. The program can be easily scaled up for delivery as an early preventive intervention and may represent a less expensive option for service delivery.

Effect of nitazoxanide in adults and adolescents with acute uncomplicated influenza: a double-blind, randomised, placebo-controlled, phase 2b/3 trial.

Background: Influenza is an important cause of morbidity and mortality worldwide. Treatment options are scarce, and new drugs with novel mechanisms of action are needed. We aimed to assess the efficacy and safety of nitazoxanide, a thiazolide anti-infective, for treatment of acute uncomplicated influenza. Methods: We did a double-blind, randomised, placebo-controlled, phase 2b/3 trial in 74 primary care clinics in the USA between Dec 27, 2010, and April 30, 2011. We enrolled participants aged 12-65 years with fever, at least one respiratory symptom, and one constitutional symptom of influenza within 48 h of symptom onset. We randomly assigned participants to receive either nitazoxanide 600 mg, nitazoxanide 300 mg, or placebo twice daily for 5 days, (ratio 1:1:1) and followed them up for 28 days. Randomisation lists were computer generated and done in blocks of three. Sponsor, investigators, study monitors, patients, and laboratory personnel were all masked to treatment allocation in the study. The primary endpoint was the time from first dose to alleviation of symptoms. The primary analysis was by intention-to-treat for participants with influenza infection confirmed by RT-PCR or culture at baseline. This trial is registered with ClinicalTrials.gov, number NCT01227421. Findings: Of 650 participants screened, 624 (96%) were enrolled. Of these, 212 were randomly assigned to receive placebo twice a day, 201 to receive nitazoxanide 300 mg twice a day, and 211 to receive nitazoxanide 600 mg a day. The median duration of symptoms for participants receiving placebo was 116·7 h (95% CI 108·1-122·1) compared with 95·5 h (84·0-108·0; p=0·0084) for those receiving 600 mg nitazoxanide and 109·1 h (96·1-129·5, p=0·52) for those receiving 300 mg nitazoxanide. Adverse events were similar between the three groups, the most common being headache reported by 24 (11%) of 212 patients enrolled in placebo group, 12 (6%) of 201 patients in the low-dose group, and 17 (8%) of 211 patients in the high-dose group, or diarrhoea, reported by seven (3%) patients in the placebo group, four (2%) patients enrolled in the low-dose group, and 17 (8%) patients in the high-dose group. Interpretation: Treatment with nitazoxanide 600 mg twice daily for 5 days was associated with a reduction of the duration of symptoms in participants with acute uncomplicated influenza. Further studies are warranted to confirm these findings and to assess efficacy of the drug alone or in combination with existing drugs in seriously ill patients and those at risk of influenza complications.

Early use of vacuum constriction device following radical prostatectomy facilitates early sexual activity and potentially earlier return of erectile function.

To assess the efficacy of vacuum constriction devices (VCD) following radical prostatectomy (RP) and determine whether early use of VCD facilitates early sexual activity and potentially earlier return of erectile function. This prospective study consisted of 109 patients who underwent nerve-sparing (NS) or non-nerve-sparing (NNS) RP between August 1999 and October 2001 and developed erectile dysfunction following surgery. The patients were randomized to VCD use daily for 9 months (Group 1, N=74) or observation without any erectogenic treatment (Group 2, N=35). Treatment efficacy was analyzed by responses to the Sexual Health Inventory of Men (SHIM) (abridged 5-item International Index of Erectile Function (IIEF-5)), which were stratified by the NS status. Patient outcome regarding compliance, change in penile length, return of natural erection, and ability for vaginal intercourse were also assessed. The mean patient age was 58.2 years, and the minimum follow-up was 9 months. Use of VCD began at an average of 3.9 weeks after RP. In Group 1, 80% (60/74) successfully used their VCD with a constriction ring for vaginal intercourse at a frequency of twice/week with an overall spousal satisfaction rate of 55% (33/60). In all, 19 of these 60 patients (32%) reported return of natural erections at 9 months, with 10/60 (17%) having erections sufficient for vaginal intercourse. The abridged IIEF-5 score significantly increased after VCD use in both the NS and NNS groups. After a mean use of 3 months, 14/74 (18%) discontinued treatment. In Group 2, 37% (13/35) of patients regained spontaneous erections at a minimum follow-up of 9 months after surgery. However, only four of these patients (29%) had erections sufficient for successful vaginal intercourse and rest of patients (71%) sought adjuvant treatment. Of the 60 successful users, 14 (23%) reported a decrease in penile length and circumference at 9 months (range, 4-8 months) compared to 12/14 (85%) among the nonresponders. However, in control group 22/35 reported decrease in penile length and circumference. Early use of VCD following RP facilitates early sexual intercourse, early patient/spousal sexual satisfaction, and potentially an earlier return of natural erections sufficient for vaginal penetration.

The effect of empagliflozin on arterial stiffness and heart rate variability in subjects with uncomplicated type 1 diabetes mellitus.

Background: Individuals with type 1 diabetes mellitus are at high risk for the development of hypertension, contributing to cardiovascular complications. Hyperglycaemia-mediated neurohormonal activation increases arterial stiffness, and is an important contributing factor for hypertension. Since the sodium glucose cotransport-2 (SGLT2) inhibitor empagliflozin lowers blood pressure and HbA1c in type 1 diabetes mellitus, we hypothesized that this agent would also reduce arterial stiffness and markers of sympathetic nervous system activity. Methods: Blood pressure, arterial stiffness, heart rate variability (HRV) and circulating adrenergic mediators were measured during clamped euglycaemia (blood glucose 4-6 mmol/L) and hyperglycaemia (blood glucose 9-11 mmol/L) in 40 normotensive type 1 diabetes mellitus patients. Studies were repeated after 8 weeks of empagliflozin (25 mg once daily). Results: In response to empagliflozin during clamped euglycaemia, systolic blood pressure (111 ± 9 to 109 ± 9 mmHg, p = 0.02) and augmentation indices at the radial (-52% ± 16 to -57% ± 17, p = 0.0001), carotid (+1.3 ± 1 7.0 to -5.7 ± 17.0%, p < 0.0001) and aortic positions (+0.1 ± 13.4 to -6.2 ± 14.3%, p < 0.0001) declined. Similar effects on arterial stiffness were observed during clamped hyperglycaemia without changing blood pressure under this condition. Carotid-radial pulse wave velocity decreased significantly under both glycemic conditions (p ≤ 0.0001), while declines in carotid-femoral pulse wave velocity were only significant during clamped hyperglycaemia (5.7 ± 1.1 to 5.2 ± 0.9 m/s, p = 0.0017). HRV, plasma noradrenalin and adrenaline remained unchanged under both clamped euglycemic and hyperglycemic conditions. Conclusions: Empagliflozin is associated with a decline in arterial stiffness in young type 1 diabetes mellitus subjects. The underlying mechanisms may relate to pleiotropic actions of SGLT2 inhibition, including glucose lowering, antihypertensive and weight reduction effects.

Patients' and Parents' Needs, Attitudes, and Perceptions About Early Palliative Care Integration in Pediatric Oncology.

Importance: Early palliative care integration for cancer patients is now touted as the optimal care model, yet significant barriers often prevent its implementation. A perceived barrier, especially for pediatric oncology patients, is the notion that patients and their families may not need or want palliative care involvement early in the disease trajectory. Objective: To determine the perception of symptom burden early in treatment and assess attitudes toward early integration of palliative care in pediatric oncology patient-parent pairs. Design, setting, and participants: Novel but pretested survey tools were administered to 129 patient-parent dyads of hospital-based pediatric oncology ambulatory clinics and inpatient units between September 2011 and January 2015. All patient participants were aged between 10 and 17 years and were diagnosed as having an oncologic condition 1 month to 1 year before enrollment. Both the patient and the parent in the dyad spoke English, and all participating parents provided written informed consent. A convenience sample was used for selection, with participants screened when otherwise presenting at a participating site. A total of 280 eligible participants were approached for study inclusion, 258 of whom were enrolled in the study (92.1% positive response-rate). Main outcomes and measures: Degree of perceived suffering from early symptom-related causes, attitudes toward early palliative care integration, and patient-parent concordance. Statistical analysis included descriptive statistics, calculation of concordance, McNemar test results, and Cochran-Armitage trend test results. Results: Of the 129 patients in the dyads, 68 were boys, and 61 girls; of the 129 parents, 15 were men, and 114 women. Patients reported the following symptoms in the first month of cancer therapy: nausea (n = 109; 84.5%), loss of appetite (n = 97; 75.2%), pain (n = 96; 74.4%), anxiety (n = 77; 59.7%), constipation (n = 69; 53.5%), depression (n = 64; 49.6%), and diarrhea (n = 52; 40.3%). A large proportion of those reporting suffering indicated substantial suffering severity from specific symptoms (ie, a great deal or a lot) including nausea, 52.3% (57 of 109), loss of appetite, 50.5% (49 of 97), constipation 30.4% (21 of 69), pain 30.2% (29 of 96), anxiety 28.6% (22 of 77), depression 28.1% (18 of 64), and diarrhea 23.1% (12 of 52). Few children and parents expressed opposition to early palliative care involvement (2 [1.6%] and 8 [6.2%]) or perceived any detrimental effects on their relationship with their oncologist (6 [4.7%] and 5 [3.9%]), loss of hope (3 [2.3%] and 10 [7.8%]), or therapy interference (3 [2.3%] and 2 [1.6%], respectively). Intradyad concordance was low overall: 26% to 29% for exact concordance and 40% to 69% for agreement within 1 response category. Significant differences in patient-parent attitudes toward aspects of early palliative care included child participants being more likely than their parents (40.3% [n = 52] vs 17.8% [n = 23]) to indicate that palliative care would have been helpful for treating their symptoms (P < .001). Conclusions and relevance: Pediatric oncology patients experience a high degree of symptom-related suffering early in cancer therapy, and very few patients or parents in this study expressed negative attitudes toward early palliative care. Our findings suggest that pediatric oncology patients and families might benefit from, and are not a barrier to, early palliative care integration in oncology.

Generally speaking, the models share an emphasis on avoidance of internal affective experiences (i.e., thoughts, beliefs, and emotions). The models cluster into three types: cognitive models (i.e., IUM, MCM), emotional/experiential (i.e., EDM, ABM), and an integrated model (AMW). This clustering offers directions for future research and new treatment strategies.

The inaugural Qatar Critical Care Conference with its Qatar Medical Journal Special Issue - An important milestone.

Dr. Ibrahim Fawzy Hassan Local Host and QCCC 2019 Conference Chair Dear Friends and Colleagues, It is an honour to welcome everyone to the first Qatar Critical Care Conference (QCCC). It has been a long journey to make it happen, but this event has been much awaited by the local critical care community. Over the last few years, we have hosted a number of related events of various scales, ranging from Critical Care Grand Rounds targeting Hamad Medical Corporation (HMC) critical care clinicians, ran specialised courses, through to organising an international medical conference on extracorporeal life support in 2017.1 This inaugural QCCC event is the fruit of much planning and collaboration. The programme spans from 28th to 31st October 2019 and consists of two days of pre-conference workshops and two days for the main conference. The vast majority of the pre-conference workshops will be held in the state-of-the-art ITQAN Clinical Simulation and Innovation Centre located within Hamad bin Khalifa Medical City. Although the facility is yet to be offically inaugurated and opened, we have the privilege to have been granted access to it as a way of showcasing our forthcoming continuing professional development capability. "Itqan" in Arabic means quality and striving for perfection, which is very much in line with the mission of our established Critical Care Network (CCNW).2 Simulation-based education is an area in which we have started to be very active through various immersive courses as well as innovative technological developments to train our extracorporeal membrane oxygenation (ECMO) specialists.3,4 The scientific part of the conference will be hosted in the iconic Sheraton Grand Doha Resort & Convention Hotel in the West Bay area. It includes a varied selection of topics presented by many renowned experts in their respective domain. This comprehensive programme with a line-up of lectures and workshops addressing e-CPR, ECMO simulation, ECMO cannulation, hemodynamics and so much more will facilitate the exchange of knowledge and experiences to improve patient care in Qatar and beyond. We anticipate that the programme will appeal to a broad audience and hence will bring together clinicians from all professions involved with caring for acutely ill patients. It is QCCC's aim to connect and explore new insights and expertise at a national and international level through networking with other professionals in a multidisciplinary setting. We hope that during this event many fruitful discussions will take place and that it will enhance opportunities for collaboration to develop everyone's practice in critical care. The HMC Critical Care family has a capacity of 163 and 109 intensive care unit (UCI) beds, respectively for adult and paediatric patients, across 7 hospitals spread throughout Qatar. These numbers are complemented by another 52 adult and paediatric beds from non-HMC hospitals. This gives us a national ICU bed capacity of 11.8 per 100,000 inhabitants considering a current population of nearly 2,750,000 inhabitants.5 Although this number remains below the international benchmark which can be considered to be around 15/100,000 population,6 this quota in Qatar has more than quadrupled over the last ten years, which represents a very significant improvement in the care that can be provided to acutely ill patients. Within HMC only, it is supported by a workforce of 159 intensive care physicians, 1122 intensive care nurses, and many other clinical staff, all of whom undergo a well regulated programme of continuing professional development and are licensed to practise by the Qatar Council for Healthcare Practitioners (QCHP).7 The work they do across the various sites is coordinated and monitored by the CCNW2 who ensures the best level of care, up-to-date technology, and evidence-based practices are consistently adopted for the wellbeing of our patients. Once again, on behalf of the Scientific and Organizing Committees, it is my pleasure to welcome you all to Doha and we hope that you enjoy and gain meaningful insights during the conference regarding our local critical care setting and practices, but also learn from the experiences and best practices shared by our international guest speakers. Prof. Guillaume Alinier Guest Managing Editor, Qatar Medical Journal QCCC Special Issue and Abstracts Chair of the QCCC Scientific Committee. Dear Contributors and Conferences Delegates, Welcome to this special issue of the Qatar Medical Journal (QMJ) which has been dedicated to the inaugural conference of the Hamad Medical Corporation (HMC) Qatar Critical Care Network (QCCN) which celebrates its fifth anniversary in 2019. I would like to start by thanking everyone who has supported this arduous publication endeavour through their extended abstract submission(s) and the reviewers for the valuable feedback they have provided to the authors to ensure this publication is a representative legacy of the calibre of this conference which includes many local and international experts in their respective field of practice or interest. All the accepted abstracts are being published Open Access thanks to the support of the conference sponsors and this contributes greatly to the sharing of experiences and best practices worldwide, but also showcases the good work that is being done in Qatar in the domain of critical care thanks to the work of dedicated clinicians and the leadership of the CCNW.2 Being the Guest Managing Editor of the special issue of a journal is an honour but also an arduous task, especially when a large number of submissions from international authors needs to be handled. It is the second time that I have accepted to take on that role for Qatar Medical Journal as the previous time was in 2017 on the occasion of hosting the South West Asia and African Chapter (SWAAC) of the Extracorporeal Life Support Organisation (ELSO) in Doha.1 This was only a couple of years after HMC had established its Extracorporeal Membrane Oxygenation (ECMO) programme, and it was a very successful event with many of its associated open access publications having been downloaded hundreds of times from the QScience.com publishing platform. Working on this new Special Issue really made me reflect on how the domain of critical care is vast and encompasses so many aspects of patient care and so many professions and specialties. The topics of the abstracts published in this special issue of QMJ cover dietetics,8 sepsis,9 delirium,10,11 physical therapy,12 end of life care and organ donation,13,14 dealing with families,15 as well as education and training of clinicians,16,17 to only highlight a few. Critical care is fast moving as new clinical practices and technological innovations are adopted and contribute to continuously improving patient care. This is especially true in Qatar where significant investments are constantly made to develop and support healthcare in a strategic way.18 At HMC, the critical care phase that some patients have to go through so their medical needs can be met is well integrated across all stakeholder departments that can possibly be involved.2 The patient's journey through the healthcare system can be seen as a continuum of care facilitated by the fact that all parties involved belong to the same overarching organisation, HMC, which is the government funded main provider of secondary and tertiary healthcare in Qatar. This means that from initial contact with the Ambulance Service bringing a patient to the Emergency Department for example, right through to rehabilitation and even possible access upon discharge to a mobile healthcare service supported by family physicians, nurses, and paramedics, patients can expect the same high standards of care.19 Critical care provision relies on multidisciplinary communication during transition of care as well as during any acute episode. This needs to be underpinned by medical knowledge and understanding of the potential contributions of other professions as nothing can be left to chance when a patient's life is hanging by a thread. The present collection of editorials and abstracts brings different perspectives on a broad range of topics which should be highly relevant to all clinicians involved with critical care and contribute to improving patient outcome and satisfaction, and hence that of the multidisciplinary team members also involved in caring for them. We hope that the Qatar Medical Journal Special Issue publications on critical care meets your needs and expectations. The complete record of QCCC publications including additional open access abstracts and editorials relating to this conference will be made available in Qatar Medical Journal at the following link: https://www.qscience.com/content/journals/qmj. Thanks again to everyone for your contributions, and beyond our email communications, I now hope to meet you in person during the conference!

Efficiency of allogeneic hematopoietic SCT from HLA fully-matched non-sibling relatives: a new prospect of exploiting extended family search.

The best donors for hematopoietic SCT (HSCT) are fully-matched siblings. In patients without fully-matched siblings, HLA registries or cord blood banks are alternative strategies with some restrictions. Owing to the high rate of consanguineous marriage in our country, between 2006 and 2013, extended family searches were undertaken in Hematology-Oncology Research Center and Stem Cell Transplantation (HORCSCT), Tehran, Iran, in 523 HSCT candidates with parental consanguinity and no available HLA identical sibling. Fully-matched other-relative donors were found for 109 cases. We retrospectively studied the HSCT outcome in these patients. Median time to neutrophil engraftment was 13 days (range: 9-31days). In 83 patients, full chimerism and in 17 patients, mixed chimerism was achieved. Acute GvHD (aGvHD) grade II-IV appeared in 36 patients (33%). The frequency of aGvHD development in various familial subgroups was NS. Five patients expired before day+100. In the surviving 104 cases, chronic GvHD developed in 20 patients (19.2%). The distantly related subgroup had significantly a higher rate of cGvHD (P=0.04). The 2-year OS and disease-free survival (DFS) were 76.7±4.5% and 71.7±4.7%, respectively. No significant difference in OS (P=0.30) and DFS (P=0.80) was unraveled between various familial relationships. Our considerable rate of fully-matched non-sibling family members and the favorable outcome support the rationale for extended family search in regions where consanguineous marriage is widely practiced.
