RESUMEN

RESEARCH QUESTION: What are the emotional effects of infertility on patients, partners, or both, and how can qualitative thematic analyses and natural language processing (NLP) help evaluate textual data? DESIGN: A cross-sectional, multi-country survey conducted between March 2019 and May 2019. A total of 1944 patients, partners, or both, from nine countries responded to the open-ended question asking about their initial feelings related to an infertility diagnosis. A mixed-method approach that integrated NLP topic modelling and thematic analyses was used to analyse responses. Sentiment polarity was quantified for each response. Linear regression evaluated the association between patient characteristics and sentiment negativity. RESULTS: Common emotional reactions to infertility diagnoses were sadness, depression, stress, disappointment, anxiety, frustration, confusion and loss of self-confidence. NLP topic modelling found additional reactions, i.e. shared feelings with partners, recollections about causes of infertility and treatment experience. Responses to the open-ended question were brief (median: three words) with 71.8% conveying negative sentiments. Some respondent characteristics showed small but significant associations with sentiment negativity, i.e. country (Spain, China and France were more negative than the USA, P < 0.001, P < 0.003 and P < 0.009 respectively), treatment engagement (no treatment was more negative than one or more treatment, P = 0.027) and marital status (missing/other was more negative than divorced, P = 0.003). CONCLUSION: Infertility diagnoses create an emotional burden for patients and partners. The mixed-method approach provides a compelling synergy in support of the validity of these findings and shows potential for these techniques in future research.

RESUMEN

Pancreatic cancer is resistant to conventional therapeutic interventions, mainly due to abundant cancer stromal cells and poor immune cell infiltration. Here, we used a targeted cancer therapy approach based on attenuated Salmonella typhimurium engineered to express cytolysin A (ClyA) to target cancer stromal cells and cancer cells and treat pancreatic cancer in mice. Nude mice bearing subcutaneous or orthotopic human pancreatic cancers were treated with engineered S. typhimurium expressing ClyA. The tumor microenvironment was monitored to analyze stromal cell numbers, stromal cell marker expression, and immune cell infiltration. The attenuated bacteria accumulated and proliferated specifically in tumor tissues after intravenous injection. The bacteria secreted ClyA into the tumor microenvironment. A single dose of ClyA-expressing Salmonella markedly inhibited growth of pancreatic cancer both in subcutaneous xenograft- and orthotopic tumor-bearing nude mice. Histological analysis revealed a marked decrease in expression of stromal cell markers and increased immune cell (neutrophils and macrophages) infiltration into tumors after colonization by ClyA-expressing bacteria. ClyA-expressing S. typhimurium destroyed cancer stromal cells and cancer cells in mouse models of human pancreatic cancer. This approach provides a novel strategy for combining anticancer and anti-stromal therapy to treat pancreatic cancer.

RESUMEN

OBJECTIVE: To describe healthcare resource utilization (HCRU) and costs, in patients with newly diagnosed heart failure (HF) according to ejection fraction (EF) in Spain. METHODS: Retrospective cohort study that analyzed anonymized, integrated and computerised medical records in Spain. Patients with ≥ 1 new HF diagnosis between January 2013 and September 2019 were included and followed-up during a 4-year period. Rates per 100 person-years of HCRU and costs were estimated. RESULTS: Nineteen thousand nine hundred sixty-one patients were included, of whom 43.5%, 26.3%, 5.1% and 25.1% had HF with reduced, preserved, mildly reduced and unknown EF, respectively. From year 1 to 4, HF rates of outpatient visits decreased from 1149.5 (95% CI 1140.8-1159.3) to 765.5 (95% CI 745.9-784.5) and hospitalizations from 61.7 (95% CI 60.9-62.7) to 15.7(14.7-16.7) per 100 person-years. The majority of HF-related healthcare resource costs per patient were due to hospitalizations (year 1-4: 63.3-38.2%), followed by indirect costs (year 1-4: 12.2-29.0%), pharmacy (year 1-4: 11.9-19.9%), and outpatient care (year 1-4: 12.6-12.9%). Mean (SD) per patient HF-related costs decreased from 2509.6 (3518.5) to 1234.6 (1534.1) Euros (50% cost reduction). At baseline, 70.1% were taking beta-blockers, 56.3% renin-angiotensin system inhibitors, 11.8% mineralocorticoid receptor antagonists and 8.9% SGLT2 inhibitors. At 12 months, these numbers were 72.3%, 65.4%, 18.9% and 9.8%, respectively. CONCLUSIONS: Although the economic burden of HF decreased over time since diagnosis, it is still substantial. This reduction could be partially related to a survival bias (sick patients died early), but also to a better HF management. Despite that, there is still much room for improvement.

RESUMEN

AIMS: To describe healthcare resource utilization (HCRU) of patients with heart failure with preserved (HFpEF), mildly reduced (HFmrEF), and reduced ejection fraction (HFrEF) in Spain.  METHODS: Adults with ≥ 1 HF diagnosis and ≥ 1 year of continuous enrolment before the corresponding index date (1/January/2016) were identified through the BIG-PAC database. Rate per 100 person-years of all-cause and HF-related HCRU during the year after the index date were estimated using bootstrapping with replacement. RESULTS: Twenty-one thousand two hundred ninety-seven patients were included, of whom 48.5% had HFrEF, 38.6% HFpEF and 4.2% HFmrEF, with the rest being of unknown EF. Mean age was 78.8 ± 11.8 years, 53.0% were men and 83.0% were in NYHA functional class II/III. At index, 67.3% of patients were taking renin angiotensin system inhibitors, 61.2% beta blockers, 23.4% aldosterone antagonists and 5.2% SGLT2 inhibitors. Rates of HF-related outpatient visits and hospitalization were 968.8 and 51.6 per 100 person-years, respectively. Overall, 31.23% of patients were hospitalized, mainly because of HF (87.88% of total hospitalizations); HF hospitalization length 21.06 ± 17.49 days (median 16; 25th, 75th percentile 9-27). HF hospitalizations were the main cost component: inpatient 73.64%, pharmacy 9.67%, outpatient 9.43%, and indirect cost 7.25%. Rates of all-cause and HF-related HCRU and healthcare cost were substantial across all HF subgroups, being higher among HFrEF compared to HFmrEF and HFpEF patients. CONCLUSIONS: HCRU and cost associated with HF are high in Spain, HF hospitalizations being the main determinant. Medication cost represented only a small proportion of total costs, suggesting that an optimization of HF therapy may reduce HF burden.

RESUMEN

BACKGROUND: Deprescribing, the supervised withdrawal of inappropriate medications, intends to manage polypharmacy, which is prevalent in older patients. AIMS: To examine general practitioner (GP) perceptions of communication processes between clinicians in hospital and GP in the community about deprescribing decisions made in hospital. METHODS: Focus groups and interviews were held with 15 GP, exploring deprescribing in hospitals, communication of deprescribing information and the format of communications. Sessions were audiotaped, transcribed and analysed using an inductive approach. RESULTS: GP stated that they should be involved in deprescribing decisions, especially for older complex patients, because of their good knowledge of their patients. Barriers to effective communication included the acute nature of hospital stays and lack of time. Facilitators included long-term relationships of GP with their patients and engaged patients. GP preferred communication of deprescribing decisions to be over the telephone while the patient was still in hospital, and with a concise, electronic discharge summary at the time of discharge. GP indicated that rationale for medication changes and recommended follow-up actions were crucial in a discharge summary to enable care post-discharge. CONCLUSIONS: GP welcome increased communication with hospital clinicians regarding deprescribing decisions made while patients are in hospital. Communication needs to be timely, transparent, succinct and accessible. Lack of time and difficulties contacting hospital clinicians challenge this process.

RESUMEN

BACKGROUND: Despite growing evidence that deprescribing can improve clinical outcomes, quality of life and reduce the likelihood of adverse drug events, the practice is not widespread, particularly in hospital settings. Clinical risk assessment tools, like the Drug Burden Index (DBI), can help prioritise patients for medication review and prioritise medications to deprescribe, but are not integrated within routine care. The aim of this study was to conduct formative usability testing of a computerised decision support (CDS) tool, based on DBI, to identify modifications required to the tool prior to trialling in practice. METHODS: Our CDS tool comprised a DBI MPage in the electronic medical record (clinical workspace) that facilitated review of a patient's DBI and medication list, access to deprescribing resources, and the ability to deprescribe. Two rounds of scenario-based formative usability testing with think-aloud protocol were used. Seventeen end-users participated in the testing, including junior and senior doctors, and pharmacists. RESULTS: Participants expressed positive views about the DBI CDS tool but testing revealed a number of clear areas for improvement. These primarily related to terminology used (i.e. what is a DBI and how is it calculated?), and consistency of functionality and display. A key finding was that users wanted the CDS tool to look and function in a similar way to other decision support tools in the electronic medical record. Modifications were made to the CDS tool in response to user feedback. CONCLUSION: Usability testing proved extremely useful for identifying components of our CDS tool that were confusing, difficult to locate or to understand. We recommend usability testing be adopted prior to implementation of any digital health intervention. We hope our revised CDS tool equips clinicians with the knowledge and confidence to consider discontinuation of inappropriate medications in routine care of hospitalised patients. In the next phase of our project, we plan to pilot test the tool in practice to evaluate its uptake and effectiveness in supporting deprescribing in routine hospital care.

RESUMEN

BACKGROUND: Symptoms due to dry eye in the form of keratoconjunctivitis sicca (KCS) are often seen after cataract surgery. We investigated the influence of cataract surgery on tear film stability on the ocular surface. MATERIAL AND METHODS: 60 eyes of 60 patients who underwent cataract surgery were included in a prospective study in 2017 at the Eye Hospital in Hanoi (Vietnam National Institute of Ophthalmology). The mean age of the patients was 65 ± 10 years. The phacoemulsification was performed under topical anaesthesia by a clear corneal incision and implantation of a foldable IOL. The parameters for the evaluation of the change of the tear film included subjective patient data using the Ocular Surface Disease Index questionnaire (OSDI), findings of the Schirmer I test, the tear break-up time (TBUT) as well as the tear meniscus height (TMH) measured noninvasively with the Keratograph 5M (Oculus). In addition, conjunctival and corneal changes were examined after vital staining with fluorescein for the cornea and rose bengal for the conjunctiva. Data were collected preoperatively, at 1 week, 1 month and 3 months postoperatively. According to DEWS, the disease is classified into 4 groups: mild, moderate, severe and very severe. RESULTS: One week after surgery, the total score according to OSDI was significantly increased with a total value of 14.4 ± 4.2 (p = 0.001). Schirmer I was 15.8 ± 4.3 mm preoperatively and decreased significantly in the first postoperative week (p = 0.001), before reaching the preoperative level again after three months. TBUT was 12.6 ± 1.5 s preoperatively, decreased significantly to 9.7 ± 1.5 s during the first postoperative week, and normalized to 12.4 ± 1.3 s by the end of the third month. The meniscus height was 0.245 ± 0.055 mm preoperatively, significantly lowered to 0.229 ± 0.057 mm in the first postoperative period and nearly normalised by the third postoperative month to 0.241 ± 0.051 mm. In the first postoperative week, the rate of mild KCS was observed in 30% of patients. At one month, this decreased to 10% and at three months was no longer demonstrable in any patient. CONCLUSION: One of three patients experienced mild KCS after cataract surgery. The symptoms lasted up to three months. This should be taken into account preoperatively and appropriate therapy should be planned.

RESUMEN

OBJECTIVE: The optimal neoadjuvant therapy for resectable pancreatic ductal adenocarcinoma (PDA) and the impact on surgical outcomes remains unclear. METHODS: S1505 (NCT02562716) was a randomized phase II study of perioperative chemotherapy with mFOLFIRINOX (Arm 1) or gemcitabine/nab-paclitaxel (Arm 2). Measured parameters included resection rate, margin positivity, pathologic response, and toxicity. RESULTS: Between 2015 and 2018, 147 patients were randomized. Of these, 44 (30%) were deemed ineligible (43 by central review). Of the 103 eligible patients, 77 (76%) completed preoperative therapy and underwent surgery; reasons patients did not undergo surgery included toxicity related to preoperative therapy (n = 9), progression (n = 9), or other (n = 7). Of the 77, 73 (95%) underwent successful resection; 21 (29%) required vascular reconstruction, 62 (85%) had negative (R0) margins, and 24 (33%) had a complete or major pathologic response to therapy. The grade 3-5 postoperative complication rate was 16%. Of the 73 patients completing surgery, 57 (78%) started and 46 (63%) completed postoperative therapy. This study represents the first prospective trial evaluating modern systemic therapy delivered in a neoadjuvant/perioperative format for resectable PDA. CONCLUSIONS: We have demonstrated: (1) Based on the high percentage of enrolled, but ineligible patients, it is clear that adherence to strict definitions of resectable PDA is challenging; (2) Patients can tolerate modern systemic therapy and undergo successful surgical resection without prohibitive perioperative complications; (3) Completion of adjuvant therapy in the perioperative format is difficult; (4) Major pathologic response rate of 33% is encouraging.

RESUMEN

In the ten years since its discovery, the Escherichia coli clone sequence type 131 (ST131) has become a major international health threat, with the multidrug-resistant and extended-spectrum ß-lactamase (ESBL)-producing clade C emerging as the globally dominant form. ST131 has previously been isolated from wastewater; however, most of these studies selectively screened for ESBL-producing organisms, thereby missing the majority of remaining ST131 clades. In this study, we used a high-throughput PCR-based screening strategy to comprehensively examine wastewater for the presence of ST131 over a 1-year period. Additional multiplex PCRs were used to differentiate clades and obtain an unbiased account of the total ST131 population structure within the collection. Furthermore, antimicrobial susceptibility profiles of all ST131-positive samples were tested against a range of commonly used antibiotics. From a total of over 3,762 E. coli wastewater samples, 1.86% (n = 70) tested positive for ST131, with the majority being clade A isolates. In total, 63% (n = 44) were clade A, 29% (n = 20) were clade B, 1% (n = 1) were clade C0, 6% (n = 4) were clade C1, and 1% (n = 1) were clade C2. In addition, a very high rate of resistance to commonly used antibiotics among wastewater isolates is reported, with 72.7% (n = 32) of clade A resistant to ciprofloxacin and high rates of resistance to gentamicin, sulfamethoxazole-trimethoprim, and tetracycline in clades that are typically sensitive to antibiotics.IMPORTANCE ST131 is a global pathogen. This clone causes urinary tract infections and is frequently isolated from human sources. However, little is known about ST131 from environmental sources. With the widely reported increase in antibiotic concentrations found in wastewater, there is additional selection pressure for the emergence of antibiotic-resistant ST131 in this niche. The unbiased screening approach reported herein revealed that previously antibiotic-sensitive lineages of ST131 are now resistant to commonly used antibiotics present in wastewater systems and may be capable of surviving UV sterilization. This is the most comprehensive account of ST131 in the wastewater niche to date and an important step in better understanding the ecology of this global pathogen.

RESUMEN

Thanks to the wide range of benefits it provides to teaching and learning, portfolio assessment has maintained widespread popularity in language education over the last few decades. However, the practical use of this assessment method is still subject to debates, particularly about the lack of clear definitions and empirical validations of the constructs underlying the assessment. This problem can be addressed by research into portfolio scale development and examination and this article reports on the process of investigating the psychometric properties of a scale assessing the portfolio-based writing competence of Vietnamese students who speak English as a foreign language (EFL). The psychometric validation in this investigation involved applying different Rasch models, including multidimensional, partial credit and many-facet models, to examine the characteristics of the scale items. The findings support the use of the scale with mostly good item functioning and acceptable raters' consistency in using the scale. Finally, only one item addressing the length of writing is removed from the developed scale and the items assessing the planning stage of writing in writing portfolios are flagged for further inspection in a larger scale study. Implications for using the scale to improve the quality of teaching and assessment of writing via portfolios can be drawn.

RESUMEN

Mutation and reassortment of highly pathogenic avian influenza A(H5N1) viruses at the animal-human interface remain a major concern for emergence of viruses with pandemic potential. To understand the relationship of H5N1 viruses circulating in poultry and those isolated from humans, comprehensive phylogenetic and molecular analyses of viruses collected from both hosts in Vietnam between 2003 and 2010 were performed. We examined the temporal and spatial distribution of human cases relative to H5N1 poultry outbreaks and characterized the genetic lineages and amino acid substitutions in each gene segment identified in humans relative to closely related viruses from avian hosts. Six hemagglutinin clades and 8 genotypes were identified in humans, all of which were initially identified in poultry. Several amino acid mutations throughout the genomes of viruses isolated from humans were identified, indicating the potential for poultry viruses infecting humans to rapidly acquire molecular markers associated with mammalian adaptation and antiviral resistance.

RESUMEN

Rural farming communities in northern Vietnam do not routinely practice vaccination for influenza A viruses (IAV) for either humans or poultry, which enables us to study transmission intensity via seroepidemiology. Using samples from a longitudinal cohort of farming households, we determined the number of symptomatic and asymptomatic human infections for seasonal IAV and avian A/H9 over 2 years. As expected, we detected virologically confirmed acute cases of seasonal IAV in humans, as well as large numbers of subclinical seroconversions to A/H1pdm [55/265 (21 %)], A/H3 [95/265 (36 %)] and A/H9 [24/265 (9 %)]. Five of the A/H9 human seroconverters likely represented true infections rather than heterosubtypic immunity, because the individuals seroconverted solely to A/H9. Among co-located poultry, we found significantly higher seroprevalance for A/H5 compared to A/H9 in both chickens and ducks [for northern study sites overall, 337/1105 (30.5 %) seropositive for A/H5 and 123/1105 (11.1 %) seropositive for A/H9].

RESUMEN

The French health care system is based on universal coverage by one of several health care insurance plans. The SNIIRAM database merges anonymous information of reimbursed claims from all these plans, linked to the national hospital-discharge summaries database system (PMSI) and the national death registry. It now covers 98.8% of the French population, over 66 million persons, from birth (or immigration) to death (or emigration), making it possibly the world's largest continuous homogeneous claims database. The database includes demographic data; health care encounters such as physician or paramedical visits, medicines, medical devices, and lab tests (without results); chronic medical conditions (ICD10 codes); hospitalisations with ICD10 codes for primary, linked and associated diagnoses, date and duration, procedures, diagnostic-related groups, and cost coding; date but currently not cause of death. The power of the database is correlatively great, and its representativeness is near perfect, since it essentially includes the whole country's population. The main difficulty in using the database, beyond its sheer size and complexity, is the administrative process necessary to access it. Recent legislative advances are making this easier. EGB (Echantillon Généraliste de Bénéficiaires) is the 1/97th random permanent representative sample of SNIIRAM, with planned 20-year longitudinal data (10 years at this time). Access time is 1 to 3 months, but its power is less (780 000 subjects). This is enough to study common issues with older drugs but may be limited for new products or rare events.

RESUMEN

AIMS: The aim of the present study was to describe the real-life usage patterns of paracetamol. METHODS: The Echantillon Généraliste de Bénéficiaires (EGB) database, the permanent 1/97 representative sample from the French national healthcare insurance system, was searched in 2011 to identify usage patterns, concomitant chronic diseases and use of cardiovascular medication in users prescribed single-ingredient (SP) and combination (CP) paracetamol, representing 85% of all sales. RESULTS: Of 526 108 subjects aged ≥15 years in the EGB, 268 725 (51%) had paracetamol dispensed on ≥1 occasion; of these, 207 707 (77%) were dispensed only SP and 61 018 (23%) received CP with or without SP. SP users were younger (48.3 years vs. 50.5 years), and 57% of SP users vs. 58% of CP users were female. Chronic comorbidities were more common in CP than SP users. SP users had, on average, 3.4 dispensings per year vs. 5.0 for CP users, for 36 defined daily doses (DDD, 3 g) of SP vs. 53 DDD per year for CP; 49% SP users bought 14 DDD or fewer; 15% bought >60 DDD. Use of paracetamol increased with age from about 16 DDD per year in 15-30-year-olds to over 90 DDD per year in patients above the age of 75; 53% of patients ≤60 years bought fewer than 14 DDD per year, whereas 55% of those >60 bought more than 30 DDD per year. More than half the dispensings exceeded the legal per-box limit of 8 g. CONCLUSIONS: Over 50% of the French adult population were dispensed paracetamol at least once over the course of a year, generally for short-term use. Considering recent misgivings on the real efficacy and safety of paracetamol, such widespread use might have important public health consequences.

Escherichia coli and attenuated Salmonella both naturally accumulate in a tumor mass, yet have distinct therapeutic efficacy: the E. coli K-12 strain (MG1655) cannot induce as significant a tumor suppression as attenuated Salmonella typhimurium, despite similar levels of accumulation in the tumor. To elucidate the mechanism of the robust antitumor effect of S. typhimurium, the cytokine profiles elicited by bacterial colonization in tumors were analyzed. C57BL/6 mice bearing MC38 tumors were injected with Salmonella or MG1655 in the tail vein. Tumors were collected 3 days post-infection and homogenized. Inflammasome-related signals were measured by real-time PCR, ELISA and western blot analysis. Only attenuated Salmonella triggered significant levels of the inflammatory cytokine IL-1ß in the tumor, whereas tumor growth was significantly suppressed. In addition, transcript levels of the core molecules of inflammasome signaling, IPAF, NLRP3 and P2X7, were significantly elevated only in Salmonella-treated tumors. Upon direct interaction between Salmonella and BMDM, BMDM expressed inflammasome-related proteins such as NLRP3, IPAF and caspase-1 p10, and secreted a significant amount of IL-1ß in supernatants. Coincubation assays with BMDM and Salmonella-treated MC38 cells (damaged cancer cells) revealed secretion of IL-1ß only when TLR4 and inflammasome were activated by both LPS and damaged cancer cells. ATP released from damaged cancer cells was also identified as a mechanism of NLRP3 activation. In conclusion, Salmonella activate the inflammasome pathway using damage signals released from cancer cells and through direct interaction with macrophages.

RESUMEN

AIMS: Most risks of nonsteroidal anti-inflammatory drugs (NSAIDs) are pharmacological, dose and duration dependent. Usage patterns of prescription-only (POM) or 'over-the-counter (OTC)' NSAIDs may influence risks, but are not commonly described. METHODS: The Echantillon Généraliste de Bénéficiaires database, the permanent 1/97 representative sample from the French national healthcare insurance systems, was queried over 2009-2010 to identify usage patterns, concomitant chronic diseases and cardiovascular medication in OTC and POM NSAID users. RESULTS: Over 2 years, 229 477 of 526 108 patients had at least one NSAID dispensation; 44 484 patients (19%) were dispensed only OTC NSAIDs (93% ibuprofen) and 121 208 (53%) only POM NSAIDs. The OTC users were younger (39.9 vs. 47.4 years old) and more often female (57 vs. 53%); 69% of OTC users and 49% of POM users had only one dispensation. A mean of 14.6 defined daily doses (DDD) were dispensed over 2 years for OTC vs. 53 for POM; 93% OTC vs. 60% POM patients bought ≤ 30 DDD over 2 years, and 1.5 vs. 12% bought ≥ 90 DDD. Chronic comorbidities were found in 19% of OTC users vs. 28% of POM users; 24 vs. 37% had at least one dispensation of a cardiovascular drug over the 2 years. CONCLUSIONS: Most of the use of NSAIDs appears to be short term, especially for OTC-type NSAIDs, such as ibuprofen. The validity of risk estimates for NSAIDs extrapolated from clinical trials or from observational studies not including OTC-type usage may need to be revised.

RESUMEN

BACKGROUND: The value of dental radiographs to oral health care decision making must be balanced with radiation safety to minimize patient exposure and occupational risk of oral health care providers. This review summarizes recommendations and regulatory guidance regarding dental radiography and cone-beam computed tomography. An expert panel presents recommendations on radiation safety, appropriate imaging practices, and reducing radiation exposure. TYPES OF STUDIES REVIEWED: A systematic search run in Ovid MEDLINE, Embase, and Cochrane Database of Systematic Reviews identified relevant topical systematic reviews, organizational guidelines, and regulatory reviews published in the peer-reviewed literature since 2010. A supplemental search of the gray literature (eg, technical reports, standards, and regulations) identified topical nonindexed publications. Inclusion criteria required relevance to primary oral health care (ie, general or pediatric dentistry). RESULTS: A total of 95 articles, guidance documents, and regulations met the inclusion criteria. Resources were characterized as applicable to all modalities, operator and occupational protection, dose reduction and optimization, and quality assurance and control. PRACTICAL IMPLICATIONS: Understanding factors affecting imaging safety and applying fundamental principles of radiation protection consistent with federal, state, and local requirements are essential for limiting patient ionizing radiation exposure, in conjunction with implementing optimal imaging procedures to support prudent use of dental radiographs and cone-beam computed tomographic imaging. The regulatory guidance and best practice recommendations summarized in this article should be followed by dentists and other oral health care providers.

RESUMEN

The difference in participants' characteristics between samples and the inconsistency in the methodology have led to variability in both direction and magnitude of association between cyber-victimization and depression in adolescents. This systematic review and meta-analysis investigates the relationship between cyber-victimization and depression in adolescents. Primary studies on cyber-victimization and depression among adolescents (10-19 years of age based on WHO definition) on PubMed and EMBASE databases were included. The forward and backward snowballing searching method was also used to explore more publications. The main effect estimate extracted from eligible studies was the odds ratio which was synthesized based on the random-effect model. The protocol of this study was prospectively registered on PROSPERO database (registration number: CRD42020185700). Among 1,008 research articles identified, 17 were eligible which comprised a total sample of 79,202 adolescents. The odds of depression among cyber-victims was almost three-fold higher (OR = 2.73; 95% CI 2.25-3.31) compared to non-cyber-victims. The overall effect estimate remained positive irrespective of differences in sample and method characteristics (study location, female percentage, sampling procedures, the use of single vs. multiple items, and elaboration of cyber-bullying definition). The presence of traditional bullying items was found to be important moderator of this relationship. However, none of the anticipated moderators had a clear impact on this relationship. Moreover, absence of publication bias was confirmed. This study confirms findings from the literature about the significant association between cyber-victimization and depression in adolescents across settings and populations. More efforts should be made to address this issue rigorously and to a greater extent.

RESUMEN

Objectives To explore general practitioners' perspectives on the discharge summaries they receive about their patients who have been discharged from hospital. Methods A survey of general practitioners in the catchment of a major metropolitan South Australian health service consisting of three teaching hospitals was undertaken. Surveys were disseminated electronically and via hardcopy mailout to general practitioners. The 36-question survey focused on five constructs of discharge summaries: accessibility, length and clarity, format, transparency, and medicines content. Results A total of 150 general practitioners responded (response rate, 27.6%). Respondents were vocationally registered (96%), predominately from metropolitan practices (90.2%), and 65.8% were female. Overwhelmingly, 86.7% of general practitioners stated that the optimal time for receipt of discharge summaries was <48 h post-discharge, and 96.6% considered that late arrival of discharge summaries adversely impacts patient care. The ideal length of discharge summaries was reported as <4 pages by 64% of respondents. A large proportion of respondents (84.6%) would like to be notified when their patients are admitted and discharged from hospital, and 82.7% were supportive of patients receiving their own copy of the discharge summary. A total of 76.7% general practitioners reported that they had detected omissions or discrepancies in the discharge summaries. Provision of rationale for medication changes was viewed as important by 86.7%, however, only 29.3% reported that it is always or often communicated. Conclusions General practitioners supported timely receipt, concise length of discharge summary and format refinement to improve the utility and communication of this important clinical handover from hospital to community care.
