A multi-institutional experience of Micro-percutaneous Nephrolithotomy (MicroPERC) for renal stones: Results and feasibility of day case surgery.

PURPOSE: To report the multi-institutional outcomes of Microperc for nephrolithiasis and to assess its feasibility in outpatient care. METHODS: We retrospectively identified all adult patients who underwent Microperc for renal stones at three centres between May 2015 and March 2021. Interventions were performed by three Surgeons. One Surgeon adopted a "one-way" strategy and all Microperc were performed on an outpatient basis, while the other two Surgeons provided inpatient monitoring for at least one day after surgery. The primary endpoint was same-day discharge after Microperc without emergency department visits or unplanned readmission within 30 days of the procedure. The secondary endpoints included treatment outcomes and the 30-day complication rate. RESULTS: Out of 72 consecutive patients included, 32 patients (44.4%) had same-day discharge. Median Charlson score (1 [0-2]) and cumulative stone size (15 [12-20] mm) were comparable between both groups. At one month post procedure, 32 patients (44.4%) were stone free and 23 patients (32%) had residual micro-fragments<3mm, conferring an overall success rate of 76.4% (inpatient Microperc group: 77.5% vs outpatient Microperc group: 75%, P=1). Analysis of the 30-day complication rate showed similar results between the two groups (Clavien I-II: 18.1%, Clavien≥III: 4.1%). After outpatient care, the rate of immediate admission and unplanned readmission was 12.5% (n=4), mainly due to urinary tract infection. CONCLUSION: In this multi-institutional study, we report that outpatient Microperc is feasible in selected patients with no significant impact on postoperative outcome.

Preoperative polymicrobial urine culture: An analysis of the risk of perioperative urinary tract infection.

PURPOSE: To report our management of preoperative polymicrobial urine culture and to determine its correlation with the risk of postoperative urinary tract infection (UTI). PATIENTS AND METHODS: We retrospectively identified all patients with preoperative polymicrobial urine culture in our center between January 2017 and October 2019. Preoperative urine cultures were collected 5 to 8 days before the surgery. No antibiotic prophylaxis was administered preoperatively in the absence of pyuria. Patients with pyuria (≥10 leukocytes/mm3) were treated preoperatively with Ceftriaxone. In case of beta-lactam allergy, the choice between other antibiotic therapies was left to the surgeon's discretion. A second urine culture was collected the day before surgery. The primary endpoint was the occurrence of UTI within 15 days following surgery. RESULTS: In all, 690 patients were included in the study. In line with our protocol, patients had Ceftriaxone, Fluoroquinolones, another antibiotic or no antibiotic prophylaxis in 492 cases (71.3%), 22 cases (3.2%), 31 cases (4.5%), and 145 cases (21%), respectively. The overall sterilization rate of 40.4% was similar between each treatment arm (P=0.54). Postoperative UTI occurred in 68 cases (10.5%). In multivariate analysis, a sterile urine culture the day before surgery was the only factor decreasing the risk of postoperative UTI (OR 0.39, 95%CI, 0.17-0.84; P=0.022). CONCLUSIONS: Our findings suggest that empirical antibiotic therapy for the treatment of preoperative polymicrobial urine culture is no longer adequate. Further evaluation of organisms isolated may provide the necessary antibiograms for initiation of susceptibility based antibiotic therapy that could decrease postoperative UTI rates.

A core outcome set for pre-eclampsia research: an international consensus development study.

OBJECTIVE: To develop a core outcome set for pre-eclampsia. DESIGN: Consensus development study. SETTING: International. POPULATION: Two hundred and eight-one healthcare professionals, 41 researchers and 110 patients, representing 56 countries, participated. METHODS: Modified Delphi method and Modified Nominal Group Technique. RESULTS: A long-list of 116 potential core outcomes was developed by combining the outcomes reported in 79 pre-eclampsia trials with those derived from thematic analysis of 30 in-depth interviews of women with lived experience of pre-eclampsia. Forty-seven consensus outcomes were identified from the Delphi process following which 14 maternal and eight offspring core outcomes were agreed at the consensus development meeting. Maternal core outcomes: death, eclampsia, stroke, cortical blindness, retinal detachment, pulmonary oedema, acute kidney injury, liver haematoma or rupture, abruption, postpartum haemorrhage, raised liver enzymes, low platelets, admission to intensive care required, and intubation and ventilation. Offspring core outcomes: stillbirth, gestational age at delivery, birthweight, small-for-gestational-age, neonatal mortality, seizures, admission to neonatal unit required and respiratory support. CONCLUSIONS: The core outcome set for pre-eclampsia should underpin future randomised trials and systematic reviews. Such implementation should ensure that future research holds the necessary reach and relevance to inform clinical practice, enhance women's care and improve the outcomes of pregnant women and their babies.

Methodological decisions influence the identification of potential core outcomes in studies related to pre-eclampsia: an analysis informing the development of recommendations for future core outcome set developers.

OBJECTIVE: To quantify the effect of different methodological decisions on the identification of potential core outcomes to inform the development of recommendations for future core coutcome set developers. DESIGN: Mixed methods study. SETTING: A core outcome set for pre-eclampsia was used as an exemplar. SAMPLE: A long list of potential core outcomes was developed by undertaking a systematic review of pre-eclampsia trials and performing a thematic analysis of in-depth patient interviews. METHODS: Specific methods used to generate long lists of potential core outcomes were evaluated. RESULTS: Different methodological decisions had a substantial impact on the identification of potential core outcomes. Extracting outcomes from published pre-eclampsia trials was an effective way of identifying 48 maternal, eight fetal, 25 neonatal outcomes, and eight patient-reported outcomes. Limiting the extraction of outcomes to primary outcomes or outcomes commonly reported in pre-eclampsia trials reduced the number and diversity of potential core outcomes identified. Thematic analysis of in-depth patient interviews ensured an additional five patient reported outcomes and six outcomes related to future child health were identified. CONCLUSIONS: Future core outcome set developers should use quantitative and qualitative methods when developing a long list of potential core outcomes.

What outcomes should researchers select, collect and report in pre-eclampsia research? A qualitative study exploring the views of women with lived experience of pre-eclampsia.

OBJECTIVE: To identify outcomes relevant to women with lived experience of pre-eclampsia. DESIGN: Qualitative interview study. SETTING: A national study conducted in the United Kingdom. SAMPLE: Purposive sample of women with lived experience of pre-eclampsia. METHODS: Thematic analysis of qualitative interview transcripts. RESULTS: Thirty women with lived experience of pre-eclampsia were interviewed. Thematic analysis identified 71 different treatment outcomes. Fifty-nine of these had been previously reported by pre-eclampsia trials. Outcomes related to maternal and neonatal morbidity, commonly reported by pre-eclampsia trials, were frequently discussed by women with lived experience of pre-eclampsia. Twelve outcomes had not been previously reported by pre-eclampsia trials. When compared with published research, it was evident that the outlook of women with lived experience of pre-eclampsia was broader. They considered pre-eclampsia in relation to the 'whole' person and attached special significance to outcomes relating to emotional wellbeing and the future health, development and wellbeing of their offspring. CONCLUSIONS: Selecting, collecting and reporting outcomes relevant to women with pre-eclampsia should ensure that future pre-eclampsia research has the necessary reach and relevance to inform clinical practice. Future core outcome set development studies should use qualitative research methods to ensure that the long list of potential core outcomes holds relevance to patients.

Inadequate safety reporting in pre-eclampsia trials: a systematic evaluation.

BACKGROUND: Randomised trials and their syntheses in meta-analyses offer a unique opportunity to assess the frequency and severity of adverse reactions. OBJECTIVE: To assess safety reporting in pre-eclampsia trials. SEARCH STRATEGY: Systematic search using bibliographic databases, including Cochrane Central Register of Controlled Trials, Embase, and MEDLINE, from inception to August 2017. SELECTION CRITERIA: Randomised trials evaluating anticonvulsant or antihypertensive medication for pre-eclampsia. DATA COLLECTION AND ANALYSIS: Descriptive statistics appraising the adequacy of adverse reaction and toxicity reporting. MAIN RESULTS: We included 60 randomised trials. Six trials (10%) were registered with the International Clinical Trials Registry Platform, two registry records referred to adverse reactions, stating 'safety and toleration' and 'possible side effects' would be collected. Twenty-six trials (43%) stated the frequency of withdrawals within each study arm, and five trials (8%) adequately reported these withdrawals. Adverse reactions were inconsistently reported across eligible trials: 24 (40%) reported no serious adverse reactions and 36 (60%) reported no mild adverse reactions. The methods of definition or measurement of adverse reactions were infrequently reported within published trial reports. CONCLUSIONS: Pre-eclampsia trials regularly omit critical information related to safety. Despite the paucity of reporting, randomised trials collect an enormous amount of safety data. Developing and implementing a minimum data set could help to improve safety reporting, permitting a more balanced assessment of interventions by considering the trade-off between the benefits and harms.

Core outcome sets in women's and newborn health: a systematic review.

BACKGROUND: Variation in outcome collection and reporting is a serious hindrance to progress in our specialty; therefore, over 80 journals have come together to support the development, dissemination, and implementation of core outcome sets. OBJECTIVE: This study systematically reviewed and characterised registered, progressing, or completed core outcome sets relevant to women's and newborn health. SEARCH STRATEGY: Systematic search using the Core Outcome Measures in Effectiveness Trial initiative and the Core Outcomes in Women's and Newborn Health initiative databases. SELECTION CRITERIA: Registry entries, protocols, systematic reviews, and core outcome sets. DATA COLLECTION AND ANALYSIS: Descriptive statistics to describe characteristics and results. RESULTS: There were 49 core outcome sets registered in maternal and newborn health, with the majority registered in 2015 (n = 22; 48%) or 2016 (n = 16; 32%). Benign gynaecology (n = 8; 16%) and newborn health (n = 3; 6%) are currently under-represented. Twenty-four (52%) core outcome sets were funded by international (n = 1; <1%), national (n = 18; 38%), and regional (n = 4; 8%) bodies. Seven protocols were published. Twenty systematic reviews have characterised the inconsistency in outcome reporting across a broad range of relevant healthcare conditions. Four core outcome sets were completed: reconstructive breast surgery (11 outcomes), preterm birth (13 outcomes), epilepsy in pregnancy (29 outcomes), and maternity care (48 outcomes). The quantitative, qualitative, and consensus methods used to develop core outcome sets varied considerably. CONCLUSIONS: Core outcome sets are currently being developed across women's and newborn health, although coverage of topics is variable. Development of further infrastructure to develop, disseminate, and implement core outcome sets is urgently required. TWEETABLE ABSTRACT: Forty-nine women's and newborn core outcome sets registered. 50% funded. 7 protocols, 20 systematic reviews, and 4 core outcome sets published. @coreoutcomes @jamesmnduffy.

Outcome reporting across randomised controlled trials evaluating therapeutic interventions for pre-eclampsia.

BACKGROUND: Standardising outcome collection and reporting in pre-eclampsia trials requires an appraisal of current outcome reporting. OBJECTIVES: To map maternal and offspring outcome reporting across randomised trials evaluating therapeutic interventions for pre-eclampsia. SEARCH STRATEGY: Randomised trials were identified by searching bibliographical databases from inception to January 2016. SELECTION CRITERIA: Randomised controlled trials. DATA COLLECTION AND ANALYSIS: We systematically extracted and categorised outcome reporting. MAIN RESULTS: Seventy-nine randomised trials, reporting data from 31 615 maternal participants and 28 172 of their offspring, were included. Fifty-five different interventions were evaluated. Included trials reported 119 different outcomes, including 72 maternal outcomes and 47 offspring outcomes. Maternal outcomes were inconsistently reported across included trials; for example, 11 trials (14%) reported maternal mortality, reporting data from 12 422 participants, and 16 trials (20%) reported cardiovascular morbidity, reporting data from 14 963 maternal participants. Forty-three trials (54%) reported fetal outcomes and 23 trials (29%) reported neonatal outcomes. Twenty-eight trials (35%) reported offspring mortality. There was poor reporting of childhood outcomes: six trials (8%) reported neurodevelopmental outcomes. Less than half of included trials reported any relevant information regarding harms for maternal participants and their offspring. CONCLUSIONS: Most randomised trials evaluating interventions for pre-eclampsia are missing information on clinically important outcomes, and in particular have neglected to evaluate efficacy and safety in the offspring of participants. Developing and implementing a minimum data set, known as a core outcome set, in future pre-eclampsia trials could help to address these issues.

Prevalence and predictors of hospital prealerting in acute stroke: a mixed methods study.

BACKGROUND: Thrombolysis can significantly reduce the burden of stroke but the time window for safe and effective treatment is short. In patients travelling to hospital via ambulance, the sending of a 'prealert' message can significantly improve the timeliness of treatment. OBJECTIVE: Examine the prevalence of hospital prealerting, the extent to which prealert protocols are followed and what factors influence emergency medical services (EMS) staff's decision to send a prealert. METHODS: Cohort study of patients admitted to two acute stroke units in West Midlands (UK) hospitals using linked data from hospital and EMS records. A logistic regression model examined the association between prealert eligibility and whether a prealert message was sent. In semistructured interviews, EMS staff were asked about their experiences of patients with suspected stroke. RESULTS: Of the 539 patients eligible for this study, 271 (51%) were recruited. Of these, only 79 (29%) were eligible for prealerting according to criteria set out in local protocols but 143 (53%) were prealerted. Increasing number of Face, Arm, Speech Test symptoms (1 symptom, OR 6.14, 95% CI 2.06 to 18.30, p=0.001; 2 symptoms, OR 31.36, 95% CI 9.91 to 99.24, p<0.001; 3 symptoms, OR 75.84, 95% CI 24.68 to 233.03, p<0.001) and EMS contact within 5 h of symptom onset (OR 2.99, 95% CI 1.37 to 6.50 p=0.006) were key predictors of prealerting but eligibility for prealert as a whole was not (OR 1.92, 95% CI 0.85 to 4.34 p=0.12). In qualitative interviews, EMS staff displayed varying understanding of prealert protocols and described frustration when their interpretation of the prealert criteria was not shared by ED staff. CONCLUSIONS: Up to half of the patients presenting with suspected stroke in this study were prealerted by EMS staff, regardless of eligibility, resulting in disagreements with ED staff during handover. Aligning the expectations of EMS and ED staff, perhaps through simplified prealert protocols, could be considered to facilitate more appropriate use of hospital prealerting in acute stroke.

Psychiatrists' views on clozapine prescribing in Ireland.

INTRODUCTION: Despite proven effectiveness in refractory schizophrenia, clozapine remains underutilised, and it is important to understand potential reasons for this. This study's aim was to examine in a National sample of Consultant Psychiatrists their knowledge of, attitudes and perceived barriers to clozapine use. METHODS: A novel questionnaire was designed and distributed by email to 275 Consultant Psychiatrists in Republic of Ireland. RESULTS: Twenty-eight percent (n = 77) completed the survey, with 55% of respondents practicing for 15 or more years. Clinicians expressed confidence in managing clozapine treatment and side effects and were well aware of clozapine's clinical effectiveness and guideline-based use. A majority indicated insufficient experience managing rechallenge and half expressed insufficient experience managing adverse events. Perceived patient factors were highlighted as barriers with 69% of respondents reporting patients' concern about effectiveness and 50% regarding tolerability. Sixty-four percent (n = 40) indicated that a specialised/tertiary clozapine service would facilitate initiation, with 57% (n = 36) reporting less frequent blood monitoring would aid clozapine prescribing. A majority identified that access to dedicated staff (81%, n = 51) and dedicated day hospital services (84%, n = 53) would facilitate community initiation. CONCLUSION: Consultants are familiar with clozapine use and related guidelines. Dedicated staff and facilities for clozapine use is one identified structural change to enhance clozapine prescribing in Ireland. Tertiary service or clinical advice service would assist in clozapine rechallenge cases or in managing significant adverse events. More structured patient education regarding clozapine effectiveness and professional development programmes focused on managing side effects and rechallenge may promote clozapine use.

The diagnostic Accuracy of Visual versus automated dipstick proteinuria testing in Pregnancy: A systematic review and Meta-Analysis.

OBJECTIVE: To evaluate the diagnostic accuracy of point-of-care (POC) tests for detecting proteinuria in pregnant women. DESIGN: Systematic review and meta-analysis. DATA SOURCES: MEDLINE and EMBASE databases were searched from inception to 13 November 2020. ELIGIBILITY CRITERIA AND DATA ANALYSIS: Included studies measured the sensitivity and specificity ofPOC proteinuria testing compared to laboratory reference standards (protein-creatinine ratio (PCR), 24-hour urine collection). Bivariate meta-analyses determined pooled sensitivity and specificity. Random-effects inverse-variance model determinedheterogeneity. MAIN OUTCOME MEASURES: The primary outcome was overall sensitivity and specificity, stratified by method of POC testing and reference standard. Secondary outcomes were sensitivity and specificity within thesubgroupstest brand, reference standard, and hypertension status. RESULTS: 1078 studies were identified, 17 studies comprising 23 comparisons were included. The meta-analysis included 13 studies with 19 comparisons. Pooled sensitivity and specificity of visual dipsticks against PCR was 72 % (95 % CI: 56 % to 84 %) and 92 % (95 % CI: 76 % to 98 %), respectively. Pooled sensitivity and specificity of visual dipsticks against 24-hour collection was 69 % (55 % to 80 %) and 70 % (51 % to 84 %), respectively. Pooled sensitivity and specificity for automated readers against PCR was 73 % (53 % to 86 %) and 91 % (83 % to 95 %), respectively. Pooled sensitivity and specificity of automated readers against 24-hour collection was 65 % (42 % to 83 %) and 82 % (46 % to 96 %), respectively. CONCLUSION: Visual dipsticks have comparable accuracy to automated readers, yet are notadequate as a rule-out test for proteinuria. Proteinuria POC testing maybe beneficial inantenatal care when repeatfollow-up tests are performed. PROSPERO Registration Number: CRD42021231914.

Familial male breast cancer is not linked to the BRCA1 locus on chromosome 17q.

Breast cancer in men is about a hundredfold less common than in women and this has hindered research into its genetic basis. We have examined 22 families with at least one case of male breast cancer for linkage to the hereditary breast and ovarian cancer locus, BRCA1, on chromosome 17q. We found strong evidence against linkage to BRCA1 (lod score-16.63) and the best estimate of the proportion of linked families was 0% (95% CI 0-18%). Our results indicate that there is a gene(s) other than BRCA1 which predisposes to early-onset breast cancer in women and which confers a higher risk of male breast cancer. Identification of additional pedigrees that include cases of male breast cancer may therefore facilitate the mapping and isolation of this gene.

Sexuality and old age.

Sexuality in older people is a multifaceted field of study. Ageing may offer opportunities for and restrictions on sexuality. Ageing individuals may have increased time for and may wish to explore their sexuality, for example, by considering a same-sex relationship, after a long-term partner dies. However, they may also lack a partner or autonomy. They may develop or have increased symptoms from chronic diseases. Consequent medication may affect their sexual functioning. Their attitudes to sex often change and their capacity for sexual activity may diminish unless they seek help. However, they may lack the confidence to do so and the health professionals consulted may be disinclined or ill-equipped to assist them. They may have concerns regarding how their sexuality or their sexual orientation would be perceived should they require residential care or start to lose their memory. We consider the recent work relating to this broad range of influences on sexuality in old age and conclude that, whilst the challenge for researchers is to accurately clarify the impact of individual factors on sexuality and identify helpful potential interventions, increased academic and educational focus on this area is enhancing the prospects for a sexually enjoyable old age.

Towards an integrated blood pressure self-monitoring solution for stroke/TIA in Ireland: a mixed methods feasibility study for the TASMIN5S IRL randomised controlled trial.

BACKGROUND: Optimising blood pressure (BP) control is one of the most important modifiable risk factors in preventing subsequent stroke where the risk increases by one-third for every 10 mmHg rise in systolic BP. This study evaluated the feasibility and potential effectiveness of blood pressure self-monitoring with planned medication titration, to inform a definitive trial of the intervention, in patients with a previous stroke or transient ischaemic attack (TIA). METHODS: Patients with a history of stroke/TIA and sub-optimal BP control were invited to take part in a mixed methods feasibility study for a randomised controlled trial. Those meeting the inclusion criteria with systolic BP >130 mmHg were randomised to a self-monitoring intervention group or usual care group. The intervention involved self-monitoring BP twice a day for 3 days within a 7-day period, every month, following text message reminders. Treatment escalation, based on a pre-agreed plan by the general practitioner (GP) and patient, was initiated according to the results of these readings. Semi-structured interviews were carried out with patients and clinicians and analysed thematically. RESULTS: Of those identified, 47% (32/68) attended for assessment. Of those assessed, 15 were eligible for recruitment and were consented and randomised to the intervention or control group on a 2:1 basis. Of those randomised, 93% (14/15) completed the study and there were no adverse events. Systolic BP was lower in the intervention group at 3 months. Participants found the intervention acceptable and easy to use. GPs found it easy to incorporate into their practice activity without increasing workload. CONCLUSIONS: TASMIN5S, an integrated blood pressure self-monitoring intervention in patients with a previous stroke/TIA, is feasible and safe to deliver in primary care. A pre-agreed three-step medication titration plan was easily implemented, increased patient involvement in their care, and had no adverse effects. This feasibility study provides important information to inform a definitive trial to determine the potential effectiveness of the intervention in patients post-stroke or TIA.

'Nesting networks': Women's experiences of social network support in high-risk pregnancy.

OBJECTIVE: Social support, an individual's social relationships (both online and offline), may provide protection against adverse mental health outcomes, such as anxiety and depression, which are high in women who have been hospitalised with high-risk pregnancy. This study explored the social support available to women at higher risk of preeclampsia during pregnancy by examining personal social networks. DESIGN: Semi-structured interviews were accompanied by social network mapping using the web-based social networking tool GENIE. SETTING: England. PARTICIPANTS: Twenty-one women were recruited, of whom 18 were interviewed both during pregnancy and postnatally between April 2019 and April 2020. Nineteen women completed maps pre-natally, 17 women completed maps pre-natally and post-natally. Women were taking part in the BUMP study, a randomised clinical trial that included 2441 pregnant individuals at higher risk of preeclampsia and recruited at a mean of 20 weeks' gestation from 15 hospital maternity units in England between November 2018 and October 2019. RESULTS: Women's social networks tightened during pregnancy. The inner network changed most dramatically postnatally with women reporting fewer network members. Interviews revealed networks were primarily 'real-life' rather than online social networks, with members providing emotional, informational, and practical support. Women with a high-risk pregnancy valued the relationships they developed with health professionals during pregnancy, and would like their midwife to have a more central role in their networks by providing informational and, where needed, emotional support. The social network mapping data supported the qualitative accounts of changing networks across high-risk pregnancy. CONCLUSION: Women with a high-risk pregnancy seek to build "nesting networks" to support them through pregnancy into motherhood. Different types of support are sought from trusted sources. Midwives can play a key role. PRACTICE IMPLICATIONS: As well as highlighting other potential needs during pregnancy and the ways in which they can be met, support from midwives has a key role. Through talking to women early in their pregnancy, signposting information and explaining ways to contact health professionals regarding informational or emotional support would fill a gap that currently is met by other aspects of their network.

Effect of exercise intensity and duration on capillary glucose responses in pregnant women at low and high risk for gestational diabetes.

BACKGROUND: Exercise may influence glucose metabolism during pregnancy. We examined the effect of exercise intensity and duration on capillary glucose responses in pregnant women at low and high risk for gestational diabetes mellitus (GDM) who followed a modified GDM meal plan. METHODS: Randomization occurred at study entry (16-20 weeks' gestation) into a low-intensity [30% heart rate reserve, low risk-30%I, n = 12; high risk-30%I, n = 11] or vigorous-intensity (70% heart rate reserve, low risk-70%I, n = 12; R-70%I, n = 11) exercise program with similar nutritional control. Exercise consisted of walking three to four times a week, gradually increasing time from 25 to 40 min/session. Free-living capillary glucose concentrations were measured once a week pre-exercise and post-exercise. RESULTS: Capillary glucose responses to exercise were strongly influenced by an interaction between GDM risk, exercise duration and exercise intensity (p = 0.006). Decreases in glucose concentrations were observed after 25 (4 ± 13%), 35 (21 ± 12%) and 40 min (15 ± 18%) of walking in high risk-30%I women, with the most noticeable decline after 35 and 40 min. In the high risk-70%I, glucose concentrations decreased significantly only after 25 (22 ± 14%) and 35 min (7 ± 23%) and increasing the exercise time attenuated glucose concentrations decline. In low risk women, regardless of exercise intensity and duration, decreases in glucose concentrations were significant and similar. CONCLUSION: To achieve the best decline in glucose concentrations, pregnant women who follow a modified GDM meal plan should walk for 25 min/session at vigorous intensity or for 35-40 min/session at low intensity if they are at risk for GDM and for at least 25 min at either low or vigorous intensity if they are at low risk for GDM.

Management of hypertension in the digital era: Perspectives and future directions.

Information and communication technology (ICT) have advanced remarkably in recent years. In the field of medicine, the problem of hypertension management seems especially well-suited to the application of novel methods. In patients with hypertension, it is important to assess blood pressure (BP) levels throughout the day and night, along with circadian BP variation, using out-of-office BP monitoring. ICT is an attractive tool to facilitate such monitoring and promises to change the current management of hypertension. The combination of self-telemonitoring of BP with lifestyle modification appears to be effective for strict BP control. ICT could be a solution to the challenging problem of nonadherence to antihypertensive medications and could reduce so-called clinical inertia in the treatment of hypertension. ICT approaches would be especially useful in geographically isolated areas or during natural disasters or complex health emergencies such as the ongoing coronavirus pandemic. However, it will be necessary to develop innovative ICT devices for easy and accurate BP measurement in a range of individuals, including the elderly, and to confirm their effectiveness in large scale clinical trials. ICT-based management of hypertension is expected to be pivotal for reducing the public-health burden of cardiovascular diseases and to be widely adopted in daily clinical practice in the future.

Perceptions and experiences of blood pressure self-monitoring during hypertensive pregnancy: A qualitative analysis of women's and clinicians' experiences in the OPTIMUM-BP trial.

BACKGROUND: Self-monitoring of blood pressure (BP) has been shown to be effective at improving BP control in the general population. The OPTIMUM-BP feasibility study was a prospective randomised controlled trial of self-monitoring of BP (SMBP) during hypertensive pregnancy. OBJECTIVE: To explore experiences, perceptions, and use of the OPTIMUM-BP self-monitoring intervention. STUDY DESIGN: Qualitative study within the OPTIMUM-BP feasibility trial. Semi-structured interviews with a purposive sample of pregnant women with chronic hypertension (n = 24) and their clinicians (n = 8) as well as 38 ethnographic observations of antenatal visits. RESULTS: Women found self-monitoring of BP feasible and acceptable and were highly motivated and pro-active in their monitoring, reporting greater control and knowledge of BP and reassurance. Women's persistence with SMBP was driven by a perceived need to safeguard the pregnancy, particularly among those taking antihypertensive medication. Clinicians also described the intervention as acceptable, though BP variability could cause uncertainty. Clinicians used different heuristics to integrate home and clinic readings. Observations suggested close working relationships between women and clinicians were key for confident integration of self-monitoring. CONCLUSIONS: Self-monitoring of BP was acceptable both to pregnant women with hypertension and their clinicians. More research is needed to understand BP variability within pregnancy to help interpret and integrate home BP readings for improved BP management. Clinical pathways that use BP self-monitoring should aim to maintain the continuity of care and relationships that are valued and appear pivotal for the confident and safe use of self-monitoring in pregnancy.

The effect of seeking consent on the representativeness of patient cohorts: iron-deficiency anaemia and colorectal cancer.

AIM: The study aimed to establish the level of selection bias that may occur should individual patient consent be sought, by comparing characteristics of consenters and nonconsenters to a request for access to medical records within a cohort of patients diagnosed with iron-deficiency anaemia (IDA). METHOD: A cohort study and cross-sectional survey was carried out of consent preferences that compared the sociodemographic characteristics of patients providing or not providing consent for access to their records, the consent rates by participant subgroup and the predictors of consent/nonconsent. RESULTS: Of 599 patients mailed requesting consent for access to their medical records, 425 (71.0%) responses were received. Of the valid responses, explicit consent was granted by 371 (62.7%) respondents, with 47 (7.9%) refusals. The characteristics of consenters and nonconsenters differed with regard to age, gender and deprivation quartile. Nonconsent was associated with younger age (40-60 years vs 60 + years; bivariate OR = 2.84; 95% CI = 2.01-4.02), female gender (OR = 1.62; 95% CI = 1.13-2.34) and being socioeconomically deprived (OR = 1.61; 95% CI = 1.15-2.26). CONCLUSION: The current research governance framework demonstrates a conflict between protecting the rights of the individual and the development of a sound research base to improve the delivery of healthcare services for society as a whole. If epidemiological research includes data only from individuals who have given consent for access to their records, the resulting selection bias may have consequences for the scientific validity and generalizability of research findings, and ultimately the quality of patient care.
