Динамическое наблюдение за возбудителями пневмонии с летальным исходом болезни при СOVID-19 в период пандемии и в постпандемийный период

Objective. To determine the trend of circulating pneumonia pathogens and their levels of antimicrobial resistance (AMR) during the pandemic of new coronavirus infection (NCI) and in the early postpandemic period with terminal episodes. Materials and Methods. The peculiarity of this study is the study material – autopsy specimens (lung tissue) obtained from fatal pneumonia cases. Surveillance was conducted from April 2021 to June 2022 in different phases of the epidemic process of the pandemic with the inclusion of periods of decline and wave rises in incidence (I, II, III periods, a total of 435 samples were studied). Postpandemic IV period was considered from August 2022 to July 2023 – 111 samples were examined. A total of 608 bacterial isolates were isolated during postmortem examination of samples from 546 pneumonia patients. Bacteriological examination was performed by the classical method, identification of pathogens and determination of their sensitivity to germicide was performed using a Vitek 2 Compact 30 bacterial analyzer. Results. During four periods of observation there was a change in the rank position of the leading and other pathogens of pneumonia by the frequency of detection from patients: Klebsiella pneumoniae (42.7; 61.1; 62.9; 40.5%), Acinetobacter baumannii (34.0; 20.4; 12.9; 18.9%), Staphylococcus aureus (9.7; 4.3; 12.9; 20.7%), Escherichia coli (14.6; 1.8; 7.6; 11.7%), Proteus mirabilis (2.9; 0.62; 3.5; 8.1%), Pseudomonas aeruginosa (6.8; 11.1; 6.5; 7.2%), and Stenotrophomonas maltophilia (0.8; 0.6; 1.6; 2.7%). The group Enterobacter aerogenes, Serratia marcescens was isolated in 3.9; 1.9; 4.1; 3.6% of cases. Achromobacter xylosoxidans was detected in periods 2 and 4 (1.2; 0.9%). The proportion of carbapenem-resistant strains (carbR) decreased in the postpandemic period for K. pneumoniae (70.5; 81.8; 76.6; 51.1%) and remained high in all periods of observation for A. baumannii (100; 97.0; 100; 95.2%) and P. aeruginosa (57.1;77.8;72.7;100%). S. aureus was represented mainly by germicide-sensitive variants during all periods of observation. Circulation of E. coli in the postpandemic period was due to BLRS producers (63.8% of cases). All 100% of P. mirabilis strains were resistant to cefepime (IV generation cephalosporin). Thus, during the first year of follow-up in the postpandemic period, there was a decrease in the share of K. pneumoniae in the etiology of fatal pneumonias with simultaneous decrease in the level of carb R-variants against the background of decreased pressure of intensive germicide use. The frequency of isolation of fungi of the genus Candida from autopsy specimens was 8.2%. The species structure was represented by 6 species of fungi: C. albicans – 33.3%, C. glabrata – 28.6%, C. krusei – 14.3%, C. tropicalis – 14.3%, C. lusitaniae – 4.8%, C. kefyr – 4.8%. Antimycotic-resistant strains were detected among the fungi C. glabrata and C. krusei, which is probably the reason for the increased proportion of these species in autopsy specimens. Conclusion. Bacteriological study of autopsy material in fatal pneumonias is a significant direction of microbiological monitoring, which allows obtaining important information about the bacterial flora that accompanies the patient's death, about the change of priority pathogens, the extent of their resistance, and the duration of circulation of resistant forms. Key words: pneumonia, fatal outcome, COVID-19 pandemic, postpandemic period, autopsy specimens, bacterial pathogens, circulation trends

Perceived social support and quality of life in endometrial cancer patients: a longitudinal study.

This study aimed to assess the influence of medical history, perceived physician-patient communication, and perceived social support on changes in the quality of life (QoL) during the first year of follow-up in patients undergoing surgery for endometrial cancer (EC), the most prevalent gynecological cancer in Western countries, especially in Central and Eastern Europe and North America. This prospective longitudinal study included 98 EC patients. All participants completed the Short Form 36 (SF-36) and the Multidimensional Scale of Perceived Social Support (MSPSS) one month and one year after surgery. Additionally, one month after surgery, they responded to a questionnaire designed by the researchers concerning the key aspects of physician-patient communication. Our findings revealed that patients reporting high social support one month after surgery demonstrated significantly improved emotional well-being (EWB) at both one month and one year after the surgery, with statistically significant higher scores in the dimension of EWB (p<0.05). The support from a significant other at one year correlates with greater PF (p<0.005), fewer limitations due to physical health (p<0.05), less pain (p<0.05), less fatigue (p<0.05), and better general and EWB (p<0.05). This study underscores the significance of perceived social support for patients cross endometrial cancer. The multifaceted nature of social support, encompassing emotional assistance and information sharing, emerges as a pivotal factor aiding patients in confronting the challenges inherent to EC. This form of support contributes to bolstering psychological well-being and enhancing overall QoL.

Skeletal-Related Events in Patients With Multiple Myeloma: A Comprehensive Retrospective Cohort Study.

Multiple myeloma (MM) patients are at risk of skeletal-related events (SREs) like spinal cord compression, pathologic fractures, bone surgery, and radiation to bone. Real-world data regarding SREs in MM are limited. We conducted a large, retrospective, nationwide cohort study using the Korean Health Insurance Review and Assessment Service (HIRA) database from 2007 to 2018. Over a 12-year study period, we identified 6,717 patients who developed symptomatic MM. After a median follow-up of 35.1 months (interquartile range [IQR], 20.8-58.2 months), 43.6% of these patients experienced SREs, and 39.6% had four or more SREs. One in five patients (20.0%) experienced pathologic fractures within the first year of follow-up. The median time to first SRE was 9.6 months (IQR, 1.2-25.8 months), with 3.0 months in the group with prior SREs and 19.8 months in the group without prior SREs. During follow-up, 78.5% of patients received bisphosphonates. Multiple logistic regression analysis revealed several factors associated with an increased risk of SREs, including being female (odds ratio [OR], 1.44), aged 50 or older (OR, 1.87), having cerebrovascular disease (OR, 1.34), undergoing first-line chemotherapy regimens not containing bortezomib or lenalidomide (OR, 1.49), and being in the group with prior SREs and bisphosphonate use (OR, 5.63), compared to the group without prior SREs and without bisphosphonate use. This population-based study is the first to report the incidence and risk factors of SREs in Korean MM patients, which can be used to assess their bone health.

Elevated lipoprotein(a) increases risk of subsequent major adverse cardiovascular events (MACE) and coronary revascularisation in incident ASCVD patients: A cohort study from the UK Biobank

Background and aimsElevated lipoprotein(a) [Lp(a)] is a genetic driver for atherosclerotic cardiovascular disease (ASCVD). We aimed to provide novel insights into the associated risk of elevated versus normal Lp(a) levels on major adverse cardiovascular events (MACE) in an incident ASCVD cohort. MethodsThis was an observational cohort study of incident ASCVD patients. MACE counts and incidence rates (IRs) per 100-person-years were reported for patients with normal (<65 nmol/L) and elevated (>150 nmol/L) Lp(a) within the first year after incident ASCVD diagnosis and overall follow-up. Cox proportional hazard models quantified the risk of MACE associated with a 100 nmol/L increase in Lp(a). ResultsThe study cohort included 32,537 incident ASCVD patients; 5204 with elevated and 22,257 with normal Lp(a). Of those with elevated Lp(a), 41.2% had a subsequent MACE, versus 35.61% with normal Lp(a). Within the first year of follow-up, the IRs of composite MACE and coronary revascularisation were significantly higher (p < 0.001) in patients with elevated versus normal Lp(a) (IR difference 6.79 and 4.66). This trend was also observed in the overall follow-up (median 4.7 years). Using time to first subsequent MACE, a 100 nmol/L increase in Lp(a) was associated with an 8.0% increased risk of composite MACE, and 18.6% increased risk of coronary revascularisation during the overall follow-up period. ConclusionsThe association of elevated Lp(a) with increased risk of subsequent MACE and coronary revascularisation highlights a population who may benefit from earlier and more targeted intervention for cardiovascular risk including Lp(a), particularly within the first year after ASCVD diagnosis. Proactive Lp(a) testing as part of routine clinical practice can help identify and better manage these higher-risk individuals.

Patients Characteristics and Preliminary Outcomes of Heart Failure Registry in A Middle-Income Country: Persian Registry of Cardiovascular Disease/Heart Failure (PROVE/HF)

Background: The Persian Registry of Cardiovascular disease/Heart Failure (PROVE/HF) aimed to studied the demographic, clinical, and diagnostic characteristics and treatment of patients hospitalized for heart failure (HF) and to follow them for short- and long-term outcomes. Its pilot phase started in 2015 in Isfahan aiming to evaluate its feasibility to be scaled up at the national level in later stages. This article describes the method and preliminary results of the first year registry. Materials and Methods: Information of hospitalized patients with preserved and low ejection fraction, were gathered. Patients were followed for 1, 6, and 12 months. During follow-up, information of the patients’ current status, medications used during hospitalization, and in case of death, the cause and place were assessed. Result: PROVE/HF enrolled 787 patients in the first year. The mean age of patients was 70.74 ±12.01 years, and 60.7% of them were men. The most frequent risk factors for the development of HF in the recruited patients was ischemic heart disease (77.9%), and hypertension (63.7%), respectively. The re-admission rate for patients with HF was at least once in 16% and continued until the fifth to ninth re-admission over a one-year period. Among 787 registered patients, 30.9% died in the first year of follow-up, and the in-hospital mortality was 6.2%. The mean hospitalization period was 4.88 days, and 64.2% were hospitalized for &gt;3 days. Conclusion: The annual rate of re-admission and mortality was high, and the use of medication was less than the recommended one inaccordance with the guidelines for the treatment of heart failure.  [GMJ.2018;7:e1026]Â

Cost-Effectiveness of Performing Reference Ultrasonography in Patients with Deep Vein Thrombosis.

The diagnosis of recurrent ipsilateral deep vein thrombosis (DVT) with compression ultrasonography (CUS) may be hindered by residual intravascular obstruction after previous DVT. A reference CUS, an additional ultrasound performed at anticoagulant discontinuation, may improve the diagnostic work-up of suspected recurrent ipsilateral DVT by providing baseline images for future comparison. To evaluate the cost-effectiveness of routinely performing reference CUS in DVT patients. Patient-level data (n = 96) from a prospective management study (Theia study; NCT02262052) and claims data were used in a decision analytic model to compare 12 scenarios for diagnostic management of suspected recurrent ipsilateral DVT. Estimated health care costs and mortality due to misdiagnosis, recurrent venous thromboembolism, and bleeding during the first year of follow-up after presentation with suspected recurrence were compared. All six scenarios including reference CUS had higher estimated 1-year costs (€1,763-€1,913) than the six without reference CUS (€1,192-€1,474). Costs were higher because reference CUS results often remained unused, as 20% of patients (according to claims data) would return with suspected recurrent DVT. Estimated mortality was comparable in scenarios with (14.8-17.9 per 10,000 patients) and without reference CUS (14.0-18.5 per 10,000). None of the four potentially most desirable scenarios included reference CUS. One-year health care costs of diagnostic strategies for suspected recurrent ipsilateral DVT including reference CUS are higher compared to strategies without reference CUS, without mortality benefit. These results can inform policy-makers regarding use of health care resources during follow-up after DVT. From a cost-effectiveness perspective, the findings do not support the routine application of reference CUS.

First-episode psychosis intervention programme versus standard care for the clinical management of early phases of psychosis: cost analysis.

Early intervention programmes (EIPs) in psychosis have gained attention as specialised interventions to improve health-related and societal impacts for people with psychotic disorders. Previous studies have presented evidence in favour of EIPs over the first year of intervention, despite none considering the critical period before psychosis onset (5 years). To compare the associated costs of the First Episode Psychosis Intervention Program (CRUPEP) and treatment as usual (TAU) in a real-world cohort in a non-specialised psychiatric community setting. Direct and indirect mental health-related costs were calculated over 1 year and up to 7 years. Healthcare and societal costs were calculated from economic data related to the consumption of all healthcare resources, including emergency department attendances, hospital admissions, psychotropic medication prescriptions and societal costs. From a healthcare perspective, the intervention (CRUPEP) group initially showed a marginally higher cost per patient than the TAU group (€7621 TAU group v. €11 904 CRUPEP group) over the first year of follow-up. However, this difference was reversed between the groups on considering the entire follow-up, with the TAU group showing considerably higher associated costs per patient (€77 026 TAU v. €25 247 CRUPEP). The EIP (CRUPEP) showed clinical benefits and minimised the direct and indirect health-related costs of the management of psychosis. Although the CRUPEP intervention initially reported increased costs over 1 year, TAU surpassed the global costs over the entire follow-up.

The impact of SARS-CoV-2 infection on renal function in patients with biopsy-proven kidney diseases.

We sought to evaluate the long-term effects of COVID-19 on renal function in patients with biopsy-proven kidney diseases. A total of 451 patients with biopsy-proven kidney disease and at least 12 months of follow-up subsequent to COVID-19 pandemic onset were included in the study. The primary study endpoint was a composite of a persistent decline of more than 30% in eGFR or ESRD. 23.1% of patients had COVID-19 during a follow-up period of 2.5 y (0.8-2.6), while 17.6% of patients reached the composite endpoint. Those with COVID-19 were more likely to reach the composite endpoint [26.7% vs. 14.8%; OR, 2.1 (95%CI, 1.23-3.58), p = 0.006). There was a significant eGFR change in the first year of follow-up between the two study groups [-2.24 (95%CI,-4.86; 0.37) vs. +2.31 (95%CI, 0.78; 3.85) ml/min, p = 0.004], with an adjusted mean difference of -4.68 ml/min (95%CI,-7.7; -1.59)(p = 0.03). The trend for worse renal outcomes remained consistent in patients with IgAN, MN and FSGS, but not in those with LN. After multivariate adjustment, the independent predictors of the composite endpoint were baseline eGFR (HR, 0.94; 95%CI, 0.92-0.95), COVID-19 (HR, 1.91; 1.16-3.12) and male gender (HR, 1.64; 95%CI, 1.01-2.66). In multivariate linear regression analysis, COVID-19 independently determined a reduction of eGFR at 12 months by 4.62 ml/min/1.73m2 (β coefficient, -4.62; 95%CI, -7.74 to -1.5, p = 0.004). There is a significant impact of COVID-19 on long-term renal function in patients with biopsy-proven kidney diseases, leading to a greater decline of eGFR and a worse renal survival.

Potentially inappropriate drug use in myasthenia gravis: a real-world population-based cohort study in Italy.

To evaluate the use of pyridostigmine in presence of contraindications, and the use of concomitant potentially contraindicated drugs in a cohort of patients affected by Myasthenia Gravis (MG) in the Italian Regions of Lazio, Tuscany, and Umbria. This is a retrospective cohort study. A multivariate logistic regression model was used to evaluate the determinants of pyridostigmine and of potentially contraindicated drugs use in MG patients. Among 591 incident pyridostigmine users affected by MG, 91 (15.4%) had at least one of the contraindications considered at the first prescription of pyridostigmine. Patients prescribed with pyridostigmine in presence of contraindications were more frequently affected by diabetes, obesity, and renal diseases. Age 75+ years (odds ratio, OR 4.94, 95% confidence interval, CI 1.60-15.22 for Latium; OR 3.78, 95%CI: 1.26-11.34 for Tuscany; OR 5.83, 95%CI 1.19-28.52 for Umbria), the presence of at least one specific comorbidity (OR 3.93; 95%CI 1.68-9.17 for Latium), and polytherapy (6+ drugs, OR 4.90, 95%CI: 1.35-17.85 for Tuscany) were found to be significantly associated with pyridostigmine use in presence of contraindications. Among patients affected by MG, 1,483 (62.6%) were treated with potentially contraindicated drugs in the first year of follow-up (67.06.9% in Latium; 59% in Tuscany; 57.6% in Umbria). Patients aged 75+ years, those with at least one specific complication or comorbidity, and those exposed to polytherapy were more likely to be treated with a potential contraindicated drug. Among incident users of pyridostigmine, more than 15% of patients have at least one of the contraindications considered, and among patients diagnosed with MG, in the first year of follow-up >60% of subjects were treated with potentially contraindicated drugs.

Risk of Type 1 Diabetes Mellitus in Patients with Atopic Dermatitis: A Nationwide Population-Based Cohort Study

Introduction: Atopic dermatitis (AD) is a disease frequently occurring in children. The immune response is characterized by T-helper (Th)-2-dependent inflammation. Type 1 diabetes mellitus (T1DM) is an autoimmune disease that destroys pancreatic islet beta cells. In contrast, it is mainly mediated by a Th-1-dependent response. An inverted association has been hypothesized between T1DM and AD since Th1 and Th2 responses are mutually inhibitory. Methods: Data was retrieved from a nationwide healthcare database in Taiwan. A logistic regression model was used to evaluate the association of T1DM in patients with AD within a year. A Cox proportional hazards analysis was used to evaluate the subsequent risk of developing T1DM 1 year after AD diagnosis. Results: We identified 396,461 patients with AD and 1,585,844 age- and sex-matched controls. During the first year of follow-up, after adjusting variates, the association between T1DM and AD showed no statistical differences (odds ratio: 1.40; 95% confidence interval [CI]: 0.83–2.38, p = 0.207). After excluding those T1DM cases within 1 year of AD diagnosis and those with a follow-up duration of less than 1 year, AD did not significantly increase the risk of T1DM (hazard ratio [HR]: 1.02; 95% CI, 0.83–1.25, p = 0.843). Conclusions: Our study revealed that there was no significant association between AD and T1DM in the first year after AD diagnosis, and there was no increased risk of T1DM in AD patients in the average 5-year follow-up in our study.

Evaluation of the First-Dose Anti-VEGF Anatomical Response in Polypoidal Choroidal Vasculopathy Patients: Correlation with the Third-Dose Response and Risk Factor Analysis

Introduction: The aims of the study were to investigate whether first-dose efficacy can predict third-dose anatomical response and analyze the risk factors for first-dose response of polypoidal choroidal vasculopathy (PCV) patients. Methods: We retrospectively reviewed patients’ medical records from 27 centers of China PCV Research Alliance. PCV patients treated with intravitreal injections of conbercept (IVC) based on the 3+ pro re nata regimen (three initial monthly injections, followed by injections as needed) with complete 3-month injection data were included. Response correlations, risk factor associations, changes in central macular thickness (CMT) or best-corrected visual acuity (BCVA), and number of injections in the first year of follow-up were evaluated separately in the pachy-PCV and non-pachy-PCV phenotypes. Results: Overall, 165 eligible patients were included. There was a significant correlation between first-dose and third-dose anatomical response in pachy-PCV or non-pachy-PCV patients (rs = 0.611, p < 0.001; rs = 0.638, p < 0.001). Multivariate analysis revealed associations of good first-dose anatomical response in pachy-PCV patients with baseline CMT with a predicted area under the curve (AUC) of 0.847, while a good response in non-pachy-PCV patients was associated with baseline BCVA, baseline CMT, pigment epithelial detachment (PED) height, higher proportion of intraretinal fluid, and lower PED minimum diameter with a predicted AUC of 0.940. CMT in the good first-dose response group was significantly decreased from baseline at all first-year follow-up visits in both groups (p < 0.001), and mean BCVA was improved in the good versus poor first-dose anatomical response group (5.4 vs. 1.6 ETDRS letters in pachy-PCV, 10.6 vs. 7.4 letters in non-pachy-PCV) after the third injection. No significant difference was observed in the number of injections in the first year of follow-up between different response groups. Conclusion: In PCV patients receiving IVC, the first- and third-dose responses are significantly correlated, and different factors influence the first-dose response in different subtypes of PCV.

Sacral Neuromodulation for defecation disorders after non oncologic pelvic surgery

PurposeDefecation disorders (DD) can sometimes affect the outcomes of pelvic or colorectal surgery. The aim of the present study is to evaluate the role of sacral neuromodulation for the treatment of constipation and other evacuation disorders after surgery.MethodsA retrospective analysis in all the consecutive patients that underwent sacral nerve modulation (SNM) for DD arisen or worsened after pelvic or colorectal surgery was performed from January 2010 to December 2020. DD were defined starting from Rome IV Criteria, and according to manometric results, all patients were further divided into the two subgroups: inadequate defecatory propulsion and dyssynergic defecation. Cleveland Clinic Constipations Score (CCCS) and SF-36 have been evaluated in the time.ResultsThirty-seven patients have been included in the study. Twenty-seven out of thirty-seven (73.3%) patients had experienced sufficient benefits to implant the definitive device, and 22 patients (59.4% of tested and 81.5% of permanently implanted) still had the device functioning after a mean follow-up of 6.3 years. The most represented manometric pattern was inadequate propulsive function (59% of patients). CCCS at preoperative assessment for all patients was 17.5 with a reduction to 10.4 at the first year of follow-up (p < 0.001).ConclusionSNM appears to be a feasible, safe, and well-tolerated procedure with durable benefit in the long-term treatment of defecatory dysfunction after pelvic or colorectal surgery for benign diseases.

Gynecological cancer survivors' experiences with sexual health communication in nurse-led follow-up consultations.

Gynecological cancer and its treatment may cause sexual difficulties in terms of physical and psychosocial health. Considering the essential role that nurses play in cancer care, they are well positioned to be ideal providers for addressing sexual health concerns in the follow-up phase of gynecological cancer. The aim of this study was to gain in-depth knowledge of how gynecological cancer survivors experience sexual health communication in nurse-led follow-up consultations. Using a qualitative hermeneutic approach, we conducted individual semi-structured interviews with 17 women from five different hospitals in Norway between April 4, 2022, and June 2, 2022. The women participated in a large intervention study on cancer follow-up that included sexual health as one of several topics addressed by trained nurses in three consultations in the first year of follow-up. A five-stage Gadamerian-inspired research method was utilized for data collection and analysis. We identified three themes: (1) the importance of nurses listening to the women's own perceptions of sexuality, (2) post-treatment sexual challenges influence the women's need to communicate about sexual health, and (3) nursing communication can help women regain their sexual health. Women who have undergone treatment for gynecological cancer find communication with trained nurses regarding sexual health beneficial. We recommend integration of trained nurses in the follow-up team. The nurses should adjust communication according to each gynecological cancer survivor's unique understanding of sexuality and inform women with sexual health concerns at that end of treatment, that sexual health can improve during follow-up.

How is the COVID-19 pandemic impacting our life, mental health, and well-being? Design and preliminary findings of the pan-Canadian longitudinal COHESION study

BackgroundWith the advent of the COVID-19 pandemic, in-person social interactions and opportunities for accessing resources that sustain health and well-being have drastically reduced. We therefore designed the pan-Canadian prospective COVID-19: HEalth and Social Inequities across Neighbourhoods (COHESION) cohort to provide a deeper understanding of how the COVID-19 pandemic context affects mental health and well-being, key determinants of health, and health inequities.MethodsThis paper presents the design of the two-phase COHESION Study, and descriptive results from the first phase conducted between May 2020 and September 2021. During that period, the COHESION research platform collected monthly data linked to COVID-19 such as infection and vaccination status, perceptions and attitudes regarding pandemic-related measures, and information on participants’ physical and mental health, well-being, sleep, loneliness, resilience, substances use, living conditions, social interactions, activities, and mobility.ResultsThe 1,268 people enrolled in the Phase 1 COHESION Study are for the most part from Ontario (47%) and Quebec (33%), aged 48 ± 16 years [mean ± standard deviation (SD)], and mainly women (78%), White (85%), with a university degree (63%), and living in large urban centers (70%). According to the 298 ± 68 (mean ± SD) prospective questionnaires completed each month on average, the first year of follow-up reveals significant temporal variations in standardized indexes of well-being, loneliness, anxiety, depression, and psychological distress.ConclusionsThe COHESION Study will allow identifying trajectories of mental health and well-being while investigating their determinants and how these may vary by subgroup, over time, and across different provinces in Canada, in varying context including the pandemic recovery period. Our findings will contribute valuable insights to the urban health field and inform future public health interventions.

Betapapillomavirus natural history and co-detection with alphapapillomavirus in cervical samples of adult women.

Human papillomaviruses (HPV) of the genus Betapapillomavirus can infect both cutaneous and mucosal sites, but research on their natural history at mucosal sites remains scarce. We examined the risk factors and co-detection patterns of HPVs of the Betapapillomavirus and Alphapapillomavirus genera in cervical samples of the Ludwig-McGill cohort study. We assessed a subset of 505 women from the Ludwig-McGill cohort study from São Paulo, Brazil. Cervical samples over the first year of follow-up were tested for DNA of over 40 alphapapillomavirus types and 43 betapapillomavirus types using a type-specific multiplex genotyping polymerase chain reaction assay. We assessed the risk factors for prevalent and incident betapapillomavirus type detection, and whether types were detected more frequently together than expected assuming independence using permutation tests, logistic regression, and Cox regression. We observed significant within-genus clustering but not cross-genus clustering. Multiple betapapillomavirus types were co-detected in the same sample 2.24 (95% confidence interval [CI]: 1.65-3.29) times more frequently than expected. Conversely, co-detections of alphapapillomavirus and betapapillomavirus types in the same sample occurred only 0.64 (95% CI: 0.51-0.83) times as often as expected under independence. In prospective analyses, positivity to one HPV genus was associated with a nonsignificant lower incidence of detection of types in the other genus. Lifetime number of sex partners and new sex partner acquisition were associated with lower risks of prevalent and incident betapapillomavirus detection. Betapapillomaviruses are commonly found in the cervicovaginal tract. Results suggest potentially different mechanisms of transmission for betapapillomavirus genital infections other than vaginal sex.

Long-term risk-factor control and secondary prevention are insufficient after first TIA: Results from QregPV.

Long-term risk-factor control and secondary prevention are not well characterized in patients with a first transient ischemic attack (TIA). With baseline levels as reference, we compared primary-care data on blood pressure (BP), low-density lipoprotein cholesterol (LDL-C), smoking, and use of antihypertensives, statins and antiplatelet treatment/oral anticoagulation (APT/OAC) during 5 years after a first TIA. Patients in QregPV, a Swedish primary-care register for the Region of Västra Götaland, with a first TIA discharge diagnosis from wards proficient in stroke care 2010 to 2012 were identified and followed up to 5 years. BP, LDL-C, smoking, use of antihypertensives, statins, APT/OAC, and achievement of target levels were calculated. We used logistic mixed-effect models to analyze the effect of follow-up over time on risk-factor control and secondary prevention treatment. We identified 942 patients without prior cerebrovascular disease who had a first TIA. Compared to baseline, the first year of follow-up was associated with improvements in concomitant attainment of BP <140/90 mmHg, LDL-C < 2.6 mmol/L and non-smoking, which rose from 20% to 33% (OR 2.08, 95% CI 1.38-3.13), but then stagnated in years 2-5. In the first year of follow-up, 47% of patients had complete secondary prevention treatment (antihypertensives, APT/OAC and statin), but continued follow-up was associated with a yearly decrease in secondary prevention treatment (OR 0.94, 95% CI 0.94-0.98). Risk-factor control was inadequate, leaving considerable potential for improved secondary prevention treatment after a first TIA in Swedish patients followed up to 5 years.

Two-year outcomes in patients after hospitalization for COVID-19: data from the TARGET-VIP registry

Aim. To evaluate 24-month outcomes after hospital treatment of patients with coronavirus disease 2019 (COVID-19) in a prospective registry.Material and methods. Two-year outcomes (2,2±0,5) after hospital treatment for COVID-19 were analyzed in 802 patients (mean age, 59,8±14,5 years, men, 51,0%). We assessed cases of death, non-fatal myocardial infarction (MI) and stroke, revascularization operations, hospitalizations, recurrent COVID-19, vaccination for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).Results. During the follow-up period, 49 (5,9%) patients died, while 7 (0,8%) patients had MI, 7 (0,8%) — stroke. In addition, 222 (26,7%) patients were hospitalized, of which 26 (3,1%) for COVID-19. Recurrent COVID-19 were revealed in 146 (17,6%) patients, while 414 (49,6%) patients were vaccinated for SARS-CoV-2. The factors of age and stay in the intensive care unit were significantly associated (p&lt;0,001) with the risk of all-cause death (hazard ratio (HR)=1,083 per 1 year of life and HR=6,28, respectively) and composite endpoint (death, non-fatal myocardial infarction, stroke, revascularization surgery): HR=1,057 and HR=3,28, respectively. Male sex was associated with the death risk (HR=2,50, p=0,003). Of the 49 deaths, 19 (38,8%) occurred in the first 3 months, and 35 (71,4%) in the first year of follow-up. A lower (1,8 times) incidence of new cases of cardiovascular (CVD) diseases and non- CVDs were associated with initial cardiovascular pathology. Hospitalization was associated with age (odds ratio (OR)=1,027; p&lt;0,001) and CVDs (OR=1,66; p=0,01). The risk of recurrent COVID-19 was higher with CVDs (OR=1,55; p=0,03), lower — among those vaccinated for SARS-CoV-2 (OR=0,49; p&lt;0,001).Conclusion. Over two-year follow-up of patients after hospital treatment for COVID-19, the proportion of deaths was 5,9%: &gt;1/3 of deaths recorded in the first 3 months and &gt;2/3 during the first year. Factors associated with death were age, male sex, and intensive care unit treatment during the hospitalization. The readmission rate was associated with older age and CVDs. The risk of repeated cases of COVID-19 was one and a half times higher in the presence of CVDs, but 2 times lower in those vaccinated for SARS-CoV-2 in the post- COVID-19 period.

Impact of Cancer Diagnosis on Appropriate Use of Antithrombotic Medications in Individuals with Cardiovascular Diseases

Introduction: Cancer and Cardiovascular disease (CVD) often coexist and CVD is the leading cause of non-cancer mortality in people with cancer. Antithrombotic medications used to manage CVD are associated with increased bleeding risk, particularly in people with cancer. Appropriate management of CVD is therefore essential in individuals with cancer, both to decrease recurrent CVD as well as to prevent bleeding. In this study, we assessed utilization patterns of antithrombotic medications for CVD following a new diagnosis of cancer. Methods: Among people receiving primary care at the University of Vermont Medical Center from 2010 to 2019, we identified a cohort of 4,010 subjects with baseline CVD, identified from problem lists or billing codes within the first year of follow-up. Exclusion criteria included baseline cancer diagnosis (cancer known at the time of inclusion in the cohort or within the first year of follow-up) or a known history of venous thrombosis. Incident cancer was defined as new diagnosis of cancer after the first year of follow-up and did not include people with non-melanomatous skin cancers. We used the National Cancer Institute list of ICD-9 and ICD-10 codes for different cancer diagnoses. Patient's use of antithrombotics, prescribed or non-prescribed, were captured using computable phenotypes developed from the electronic outpatient medication reconciliation record and validated using chart review. People with baseline CVD who were diagnosed with cancer after the first year of follow up were matched 1:1 by sex and age with people with CVD and no cancer. We used logistic regression to estimate the odds ratio (OR) and 95% confidence intervals (95% CI) of persistent guideline-directed use of antithrombotic medications for 6 months after a new cancer diagnosis versus a matched time-period in those without incident cancer (use of antiplatelets in those with a history of atherosclerotic CVD and use of anticoagulation in those with a history of atrial fibrillation). Results: We identified 4,010 individuals with baseline CVD, 841 of whom (20%) developed incident cancer during follow-up. Distribution of CVD and antithrombotic use in the age- and sex-matched population are presented in Table 1. 2/3 of the population had coronary artery disease and about 30% had atrial fibrillation or flutter. About 65% of individuals were on any antiplatelet therapy and 18% were on anticoagulation for CVD. 41% of people with baseline CVD, and incident cancer diagnosis were still on antiplatelet therapy 6 months after their cancer diagnosis as opposed to 38 % in the matched population without a cancer diagnosis. 33% of individuals with incident cancer were still on anticoagulation for atrial fibrillation or flutter as opposed to 28% of the matched population without cancer. Both of these differences were statistically significant with OR=1.55 (95% CI, 1.15-2.1) for antiplatelets, and OR=1.56 (95% CI, 1.05,2.31) for anticoagulants, compared to those with no cancer diagnosis (Table 2). Conclusion: Surprisingly, our study found that incident cancer in individuals with baseline CVD was associated with increased adherence to antithrombotic therapy. We had hypothesized that incident cancer would be associated with lower use of antithrombotic therapy. This result could be related to increased interaction with medical specialists following a cancer diagnosis. The impact of increased adherence to antithrombotics on bleeding however, will need to be further investigated.

Demographic, Clinical, and Laboratory Characteristics of Children with Renal Tubular Acidosis

This study included patients followed up for primary renal tubular acidosis (RTA) between 1991 and 2012. Clinical characteristics at presentation, physical examination findings, laboratory test results, and treatments were recorded. The patients’ laboratory results, drug doses, height, and weight were recorded every 3 months for the first year of follow-up. Standard deviation scores (Z-scores) of height and weight for age were determined and the patients’ growth rates were evaluated. Of 50 patients followed up for primary RTA, 31 (62%) had distal RTA and 19 (38%) had proximal RTA. The median age at diagnosis was 3 months (range, 1-174 months) for patients with distal RTA and 10 months (range, 2-33 months) for patients with proximal RTA. The median follow-up times in these two groups were 96 months (range, 6-204 months) and 89 months (range, 6-180 months), respectively. Family history of RTA was more common among patients with distal RTA than those with proximal RTA (p=0.013). Nephrocalcinosis and deafness were detected more frequently in the distal RTA group (p=0.001), while ocular pathologies were more common in the proximal RTA group (p&lt;0.001). In patients with distal RTA, older age at diagnosis was associated with lower weight and height Z-scores (p&lt;0.05). Early diagnosis had a positive effect on the growth of patients with primary RTA.

Weight change in chronic kidney disease: Association with mortality and kidney function.

Excess body weight is a risk factor for the progression of chronic kidney disease (CKD), but weight loss in CKD has been associated with higher mortality. Consequently, blanket weight loss recommendations in this population are controversial. Little data is available on the patterns of weight-change in CKD. The authors aimed to describe weight-changes in moderate/severe CKD and explore associations with mortality and renal endpoints in patients with overweight and obesity. Non-dialysis Canberra Hospital patients with estimated glomerular filtration (eGFR)<60mL/min/1.73m2 and body mass index (BMI) ≥25kg/m2 were followed for up to 5.5years. Weight-change ≥5% was considered clinically significant. The renal endpoint was defined as the commencement of dialysis or transplant or a ≥40% fall in eGFR. Relationships between weight-change in the first year of follow-up and mortality or the renal endpoint were assessed using Cox-regression. Three hundred ten patients (median age 75, median BMI 31kg/m2) were identified. 68% had Stage-4 CKD at baseline. Over 4.4-years median follow-up, 128 died and 140 had significant weight-change. During the first year of follow-up, 42 patients lost and 23 gained ≥5% body weight, of whom only 3 had intentionally lost weight. On multivariate regression, significant weight loss/gain at 1-year was associated with 2.74 (p<0.0005) and 2.67 (p=0.003) hazard of subsequent death and with 2.51 (p=0.004) and 2.20 (p=0.05) hazard of the renal endpoint respectively. There was no association between baseline eGFR and subsequent weight change. Patients with moderate/severe CKD experience significant weight-change, but this has no relationship to baseline kidney function. Significant weight-change is associated with higher subsequent mortality and loss of kidney function, but this association is likely significantly affected by confounding.
