RESUMO

A 2-year-old Kunekune sow was submitted for necropsy following death after peritonitis and sepsis. In addition to peritonitis, numerous fluid-filled cysts were identified in the mesentery and hepatic parenchyma, which contained an approximately 1 cm metacestode (cysticercosis). Subsequent molecular characterization confirmed the presence of Taenia hydatigena, a non-zoonotic cestode species. To our knowledge, visceral cysticercosis caused by T. hydatigena has not been previously documented in Kunekune pigs. Taenia solium is a differential diagnosis of public health importance in cases of cysticercosis. Although Taenia solium is not commonly reported nor endemic in the United States, its zoonotic potential warrants consideration in the initial diagnostic assessment. Clinicians should be aware of the presence of T. hydatigena in its definitive and intermediate hosts.

RESUMO

BACKGROUND: Within peritoneal dialysis (PD) complications, peritonitis remains a primary challenge for the long-term success of the technique. Proper technique training is essential, since it reduces peritonitis rates, but the adequacy of training has not been standardized. Furthermore, factors influencing training duration have not been well identified. METHODS: We retrospectively analyzed all consecutive training sessions of incident PD patients in our Unit from January 2001 to December 2018. RESULTS: Our analysis included 135 patients, 25.9% were diabetic and median Charlson index (CCI) was 4 (IQR 2-6). Above 13 sessions was chosen as the cut off between usual and prolonged training, as it was our cohort's 75th percentile: 23% (31) had an extended training duration as per our study definition and 77% (104) had a usual training duration. The number of training sessions required increased with age (Spearman Rho 0.404; p = 0.000001), diabetic status (p = 0.001), unemployment status (p = 0.046) and CCI (Spearman Rho 0.369; p = 0.00001). Neither gender, cohabitation status, scheduled PD start, education level nor referral origin, were significant factors impacting training duration. Requiring longer training (> 13 sessions) was a significant risk factor for higher peritonitis risk, but extended training was not related to a shorter technique survival. CONCLUSION: Number of PD training sessions depends on the patient's age and comorbidities, but is not related to social, educational or employment status. Prolonged training duration was a statistically significant predictor of higher peritonitis risk, but it was not related to shorter permanence in PD in our series. Identifying these patients since the training period would be useful to adapt training schedule as an early prevention strategy to minimize the risk of peritonitis and plan a preemptive retraining.

RESUMO

People who use injection drugs (PWID) experience high rates of HIV acquisition and, as a result of lower rates of optimal access and adherence to combination antiretroviral therapy (ART), experience worse HIV treatment outcomes than other key affected populations. However, the incidence and risk factors for the development of AIDS among HIV-positive PWID have not been completely described. We used data from a community-recruited prospective cohort of HIV-positive PWID in Vancouver, Canada, a setting with universal no-cost ART and a comprehensive clinical monitoring registry. We used multivariable extended Cox models to identify factors associated with time to AIDS. Between 1996 and 2017, 396 participants, including 140 (35.4%) women, were followed for a median of 39.0 months (interquartile range: 16.6-76.2), among whom 165 (41.7%) developed AIDS. In a multivariable model, homelessness (Adjusted Hazard Ratio [AHR] = 1.76 (1.18-2.61)) and injection drug use within the preceding six months (AHR = 1.74 (1.17-2.58)) were independently associated with a higher risk of developing AIDS. Despite widespread scale-up of programmes to improve ART utilization, significant risk factors for the development of AIDS remain among HIV-positive PWID in this setting.

RESUMO

BACKGROUND: Causes of non-resuming peritoneal dialysis (PD) after complicated peritonitis requiring peritoneal catheter (PC) removal remain poorly studied. METHODS: We reviewed all peritonitis episodes in our center between 1997 and 2017. Patients who restarted PD after PC removal (Group 1) were compared to those who did not (Group 2), identifying the causes. RESULTS: Of 284 peritonitis episodes, PC was removed in 48 patients (16.9%). In 18 (37.5%) patients PC was reinserted, and PD successfully resumed in all, with a median duration of PD afterwards of 14.1 months. In other 30 (62.5%) reinsertion of PC was not attempted. Causes of non-reinsertion were: transfer to hemodialysis 76.6% (n = 23), death 16.7% (n = 5) and transplantation 6.7% (n = 2). Hemodialysis switch was due to non-medical reasons in 47.8% (n = 11) including fear of peritonitis, family decision and social dependence. Group 1 was younger (p = 0.041), with lower Charlson index (p = 0.045) and higher men proportion (p = 0.049). Group 1 had a better patient survival than group 2 (survival at 24 months: 67% and 53%, respectively; log-rank test p: 0.01). There were no differences in survival between groups when adjusted for significant basal characteristics. CONCLUSIONS: Resuming PD after severe peritonitis requiring PC removal is feasible but a high proportion of patients do not restart PD for non-medical reasons, usually older patients with higher Charlson index. A properly structured interview would be a useful tool that could improve return to technique in these patients.

RESUMO

OBJECTIVES: We sought to examine the association between dispensation of methadone maintenance therapy (MMT) and antiretroviral therapy (ART) at the same facility, across multiple low-barrier dispensing outlets, and achieving optimal adherence to ART among people who use illicit drugs (PWUD). METHODS: We used data from the AIDS Care Cohort to Evaluate Exposure to Survival Services (ACCESS) study, a long-running study of a community-recruited cohort of HIV-positive PWUD, linked to comprehensive HIV clinical records in Vancouver, Canada, a setting of no-cost, universal access to HIV care. The longitudinal relationship between MMT-ART dispensation at the same facility and the odds of ≥ 95% ART adherence was analysed using multivariable generalized linear mixed-effects modelling. We conducted a further analysis using a marginal structural mode with inverse probability of treatment weights as a sensitivity analysis. RESULTS: This study included data on 1690 interviews of 345 ART- and MMT-exposed participants carried out between June 2012 and December 2017. In the final multivariable model, MMT-ART dispensation, compared with nondispensation at the same facility, was associated with greater odds of achieving ≥ 95% adherence [adjusted odds ratio (AOR) 1.56; 95% confidence interval (CI) 1.26-1.96]. A marginal structural model estimated a 1.48 (95% CI 1.15-1.80) greater odds of ≥ 95% adherence among participants who reported MMT-ART dispensation at the same facility compared with those who did not. CONCLUSIONS: The odds of achieving optimal adherence to ART were 56% higher during periods in which MMT and ART medications were dispensed at the same facility, in a low-barrier setting. Our findings highlight the need to consider a simpler integrated approach with medication dispensation at the same facility in low-threshold settings.

RESUMO

PURPOSE: The acute respiratory distress syndrome (ARDS) represents a major challenge for clinicians as well as basic scientists. The mortality rate for ARDS has been maintained within the range of 40-52%. The authors have examined the involvement of the "cardiotonic steroids" in the pathogenesis and therapy of ARDS. We have studied the possible role of the bufadienolide, marinobufagenin (MBG), in the pathogenesis of ARDS in both a rat model of ARDS and in patients afflicted with that disorder. In addition, the potential therapeutic benefit of an antagonist of MBG, resibufogenin (RBG), in an animal model has been evaluated. METHOD: A syndrome resembling human ARDS was produced in the rat by exposing the animals to 100% oxygen for 48 h. In other animals, RBG was administered to these "hyperoxic" rats, and the serum MBG was measured. In human ICU patients, urinary samples were examined for levels of MBG, and the values were compared to those obtained from other ICU patients admitted with diagnoses other than ARDS. RESULTS: (1) Exposure of rats to hyperoxia produced a histologic picture which resembled that of human ARDS. (2) Serum levels of MBG in the "hyperoxic" rats substantially exceeded those obtained in animals exposed to ambient oxygen levels and were reduced to normal by RBG. (3) In ARDS patients, substantial elevations in urinary MBG were obtained compared to those in non-ARDS ICU patients. CONCLUSIONS: MBG may serve as an important biomarker for the development of ARDS, and RBG may represent a preventative/therapy in this disorder.

RESUMO

BACKGROUND: Percutaneous renal biopsy (PRB) is an important technique providing relevant information to guide diagnosis and treatment in renal disease. As an invasive procedure it has complications. Most studies up to date have analysed complications related to bleeding. We report the largest single-center experience on routine Doppler ultrasound (US) assessment post PRB, showing incidence and natural history of arteriovenous fistulae (AVF) post PRB. METHODS: We retrospectively analysed 327 consecutive adult PRB performed at Ramon Cajal University Hospital between January 2011 and December 2014. All biopsies were done under real-time US guidance by a trained nephrologist. Routine Doppler mapping and kidney US was done within 24 h post biopsy regardless of symptoms. Comorbidities, full blood count, clotting, bleeding time and blood pressure were recorded at the time of biopsy. Post biopsy protocol included vitals and urine void checked visually for haematuria. Logistic regression was used to investigate links between AVF, needle size, correcting for potential confounding variables. RESULTS: 46,5% were kidney transplants and 53,5% were native biopsies. Diagnostic material was obtained in 90,5% (142 grafts and 154 native). Forty-seven AVF's (14.37%) were identified with routine kidney Doppler mapping, 95% asymptomatic (n = 45), 28 in grafts (18.4%) and 17 natives (9.7%) (p-value 0.7). Both groups were comparable in terms of comorbidities, passes, cylinders or biopsy yield (p-value NS). 80% were <1 cm in size and 46.6% closed spontaneously in less than 30 days (range 3-151). Larger AVF's (1-2 cm) took a mean of 52 days to closure (range 13-151). Needle size was not statistically significant factor for AVF (p-value 0.71). CONCLUSIONS: Contrary to historical data published, AVF's are a common complication post PRB that can be easily missed. Routine US Doppler mapping performed by trained staff is a cost-effective, non-invasive tool to diagnose and follow up AVF's, helping to assess management.

RESUMO

OBJECTIVES: Since 2006, the British Columbia HIV/AIDS Drug Treatment Program (DTP) has expanded enrolment and dramatically increased its number of participants. We examined the effect this expansion has had on the underlying cause of death in HIV-infected individuals. METHODS: We analysed data from participants aged 18 years and older in the DTP to measure 2-year mortality rates and causes of death from 2001 to 2012. We conducted tests of trend for all-cause and cause-specific mortality, and compared demographics and characteristics of individuals. Cox proportional hazard models were used to determine the risk of death. RESULTS: A total of 8185 participants received antiretroviral therapy (ART) during the study period. Mortality declined from 3.88 per 100 person-years (PY) in 2001-2002 to 2.15 per 100 PY in 2011-2012 (P = 0.02). There were significant decreases in HIV-related deaths (2.34 to 0.56 per 100 PY; P = 0.02) and deaths attributable to chronic liver disease (0.20 to 0.09 per 100 PY; P = 0.01), cardiovascular disease (0.24 to 0.05 per 100 PY; P = 0.03) and suicides (0.47 to 0 per 100 PY; P = 0.003). Multivariate models, adjusted for age, gender, history of injecting drug use, AIDS diagnoses and baseline CD4 cell counts, demonstrated that initiation of ART in all time periods after 2001-2002 was independently associated with reduced mortality (P < 0.001). CONCLUSIONS: We observed declines in HIV-related mortality and certain non-HIV-related causes of death among participants in the BC DTP from 2001 to 2012. These findings suggest that there may be broader benefits to the increasingly liberal HIV treatment guidelines, including reductions in death caused by cardiovascular disease and chronic liver disease.

RESUMO

Symmetric, aligned and luminous smiles are usually classified as 'beautiful' and aesthetic. However, smile perception is not strictly governed by standardised rules. Personal traits may influence the perception of non-ideal smiles. We aimed to determine the influence of personality traits in self-rated oral health and satisfaction and in the aesthetic preference for different strategically flawed smiles shown in photographs. Smiles with dark teeth, with uneven teeth, with lip asymmetry and dental asymmetry were ordered from 1 to 4 as a function of the degree of beauty by 548 participants, of which 50·7% were females with a mean age of 41·5 ± 17·6 years (range: 16-89 years). Self-assessment and oral satisfaction were recorded on a Likert scale. Personality was measured by means of the Big Five Inventory (extraversion, agreeableness, conscientiousness, neuroticism and openness), and the Life Orientation Test was used to measure optimism and pessimism. Of the four photographs with imperfect smiles, dental asymmetry was the most highly assessed in 63% of the sample, and the worst was lip asymmetry, in 43·7% of the sample. Some personality traits (above all conscientiousness and openness) were significantly correlated with the position assigned to the photographs with dental and lip asymmetry or with misaligned teeth. The extraversion, agreeableness and openness traits were correlated with the self-perceptions of oral health and aesthetics of the participants. Dental asymmetry seems to be better tolerated than lip asymmetry. Personality traits are weakly but significantly correlated with the aesthetic preference and oral health values, conscientiousness and openness being the most relevant domains in this sense.

RESUMO

BACKGROUND: Therapeutic strategies for xerostomia, regardless of etiology, have so far not had definitive or clearly effective results. OBJECTIVES: To systematically revise the latest scientific evidence available regarding the treatment of dry mouth, regardless of the cause of the problem. MATERIAL AND METHODS: The literature search was conducted in March 2015, using the Medline and Embase databases. The "Clinical Trial", from 2006 to March 2015, was carried out in English and only on human cases. The draft of the systematic review and assessment of the methodological quality of the trials was carried out following the criteria of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and the "Oxford Quality Scale". RESULTS: Finally, a total of 26 trials were identified that met the previously defined selection and quality criteria; 14 related to drug treatments for dry mouth, 10 with non-pharmacological treatment and 2 with alternative treatments. CONCLUSIONS: Pilocarpine continues to be the best performing sialogogue drug for subjects with xerostomia due to radiation on head and neck cancer or diseases such as Sjogren's Syndrome. For patients with dry mouth caused solely by medication, there are some positive indications from the use of malic acid, along with other elements that counteract the harmful effect on dental enamel. In general, lubrication of oral mucous membrane reduces the symptoms, although the effects are short-lived.

RESUMO

OBJECTIVES: The aim of the study was to examine trends in initiating highly active antiretroviral therapy (HAART) with a CD4 count ≤ 200 cells/µL and the contribution of having a CD4 count ≤ 200 cells/µL at the time of diagnosis to these trends, in British Columbia (BC), Canada. METHODS: We included in the analysis treatment-naïve BC residents aged ≥ 19 years who initiated HAART from 2003 to 2012. Participants were classified as follows: Group 1: diagnosed and initiated HAART with a CD4 count > 200 cells/µL; Group 2: diagnosed with a CD4 count > 200 cells/µL and initiated HAART with a CD4 count ≤ 200 cells/µL; and Group 3: diagnosed and initiated HAART with a CD4 count ≤ 200 cells/µL. We measured trends in initiating HAART with a CD4 count ≤ 200 cells/µL and used logistic regression models to measure factors associated with initiating HAART with a CD4 count ≤ 200 cells/µL, stratified by having a CD4 count ≤ 200 cells/µL or > 200 cells/µL at the time of diagnosis. RESULTS: Between 2003 and 2012, 3506 BC residents initiated HAART. Of these, 44% (1558 of 3506) initiated HAART with a CD4 count ≤ 200 cells/µL. This proportion declined from 69% (198 of 287) in 2003 to 21% (81 of 330) in 2012 (P < 0.001). The proportion of those in Group 3 increased from 49% (97 of 198) in 2003 to 69% (56 of 81) in 2012 (P < 0.001). Overall, 56% (1948), 22% (776) and 22% (782) made up Groups 1, 2, and 3, respectively. In adjusted analyses, seeing a specialist was significantly associated with being in Group 3. Using injection drugs and seeing a specialist were associated with being in Group 2. CONCLUSIONS: In recent years, among individuals who ever initiated HAART in BC, being diagnosed with low CD4 cell counts has become a greater contributor to initiating HAART with low CD4 cell counts.

RESUMO

The cascade of HIV care has been proposed as a useful tool to monitor health system performance across the key stages of HIV care delivery to reduce morbidity, mortality, and HIV transmission, the focal points of HIV Treatment as Prevention campaigns. Interventions to improve the cascade at its various stages may vary substantially in their ability to deliver health value per amount expended. In order to meet global antiretroviral treatment access targets, there is an urgent need to maximize the value of health spending by prioritizing cost-effective interventions. We executed a literature review on economic evaluations of interventions to improve specific stages of the cascade of HIV care. In total, 33 articles met the criteria for inclusion in the review, 22 (67 %) of which were published within the last 5 years. Nonetheless, substantial gaps in our knowledge remain, particularly for interventions to improve linkage and retention in HIV care in developed and developing-world settings and generalized and concentrated epidemics. We make the case here that the attention of scientists and policymakers needs to turn to the development, implementation, and rigorous evaluation of interventions to improve the various stages of the cascade of HIV care.

RESUMO

Page's kidney is a condition that occurs due to external renal compression, usually caused by a subcapsular haematoma, generating a renal compartmental syndrome with parenchymal damage and renal perfusion alteration. Classically associated with renal trauma, Page's kidney can also arise after invasive renal procedures, such as renal biopsies or percutaneous nephrostomies. Clinically, it can trigger hypertension due to activation of the renin-angiotensin system induced by hypoperfusion secondary to renal parenchymal compression and can also present with varying degrees of renal function impairment. Furthermore, severe acute renal failure may be found particularly in patients with solitary kidneys or renal transplants. We present two cases of Page's kidney after renal biopsy and their PoCUS ultrasound findings. We would like to highlight the reversed diastolic flow on Doppler ultrasound in this entity, a pattern we have found in all two cases.

RESUMO

Transplantation (KTx) is considered to be the best renal replacement therapy, and improving its outcomes remains a primary challenge. KTx ureteral stenting has been used to prevent urological complications, but there is no consensus on the timing of stent removal, and literature regarding routine ultrasonography after ureteric stent removal (RUSUS) to detect complications is lacking. Point-of-care ultrasound has been gaining drive in the medical community in recent years, including nephrologists. We aimed to define the incidence of urological complications diagnosed with RUSUS, if those findings changed patient's management and ultrasound utility. Contrary to previously published data, in our cohort RUSUS allowed a timely diagnosis and early treatment of urological complications, a key factor for successful transplantation. KTx point-of-care ultrasound is a cost-effective and reproducible test that provides relevant information to guide clinical decisions, seeming most efficient when performed approximately 2 weeks post ureteral stent removal. Interventional nephrologists can promptly perform these examinations, reducing waiting times and improving graft and patient's survival.

RESUMO

INTRODUCTION: Chronic heart failure (HF) has high rates of mortality and hospitalization in patients with advanced chronic kidney disease (aCKD). However, randomized clinical trials have systematically excluded aCKD population. We have investigated current HF therapy in patients receiving clinical care in specialized aCKD units. METHODS: The Heart And Kidney Audit (HAKA) was a cross-sectional and retrospective real-world study including outpatients with aCKD and HF from 29 Spanish centers. The objective was to evaluate how the treatment of HF in patients with aCKD complied with the recommendations of the European Society of Cardiology Guidelines for the diagnosis and treatment of HF, especially regarding the foundational drugs: renin-angiotensin system inhibitors (RASi), angiotensin receptor blocker/neprilysin inhibitors (ARNI), beta-blockers (BBs), mineralocorticoid receptor antagonists (MRAs), and sodium-glucose cotransporter-2 inhibitors (SGLT2i). RESULTS: Among 5,012 aCKD patients, 532 (13%) had a diagnosis of HF. Of them, 20% had reduced ejection fraction (HFrEF), 13% mildly reduced EF (HFmrEF), and 67% preserved EF (HFpEF). Only 9.3% of patients with HFrEF were receiving quadruple therapy with RASi/ARNI, BB, MRA, and SGLT2i, but the majority were not on the maximum recommended doses. None of the patients with HFrEF and CKD G5 received quadruple therapy. Among HFmrEF patients, approximately half and two-thirds were receiving RASi and/or BB, respectively, while less than 15% received ARNI, MRA, or SGLT2i. Less than 10% of patients with HFpEF were receiving SGLT2i. CONCLUSIONS: Under real-world conditions, HF in aCKD patients is sub-optimally treated. Increased awareness of current guidelines and pragmatic trials specifically enrolling these patients represent unmet medical needs.

RESUMO

BACKGROUND: Cisplatin cures over 80% of testicular germ cell tumours (TGCTs), and nucleotide-excision repair (NER) modifies the sensitivity to cisplatin. We explored the association between NER proteins and their polymorphisms with cisplatin sensitivity (CPS) and overall survival (OS) of patients with non-seminomatous (ns)-TGCTs. METHODS: The expression of ERCC1 and XPA and the presence of γH2AX were evaluated in cancer cell lines and in fresh ns-TGCTs. The ERCC1 protein was also determined in ns-TGCTs. The differences between CPS and non-CPS cell lines and patients were analysed by Student's t- or χ(2)-tests. The differences in OS were analysed using the log-rank test, and the hazard ratios (HRs) were calculated using the Cox model. RESULTS: High ERCC1 expression was observed in the non-CPS cells, and both ERCC1 and γH2AX expressions were augmented after cisplatin treatment. Increased ERCC1 expression was also identified in non-CPS patients. Neither polymorphism was associated with either CPS or OS. The presence of ERCC1 was associated with non-CPS (P=0.05) and adjusted in the prognosis groups. The HR in ERCC1-negative and non-CPS patients was >14.43, and in ERCC1-positive and non-CPS patients the HR was >11.86 (P<0.001). CONCLUSIONS: High levels of ERCC1 were associated with non-CPS, suggesting that ERCC1 could be used as a potential indicator of the response to cisplatin and prognosis in ns-TGCTs.

RESUMO

Renal artery stenosis of the kidney allograft associated with kinking is not a frequent finding. As a correctable cause of graft dysfunction, it is important to diagnose it as soon as possible to avoid further graft damage and improve graft and patient survival. As pulsed wave Doppler ultrasound mapping of the graft's renal arteries is essential to diagnose possible alterations, point of care ultrasound (POCUS) is a highly useful tool for early diagnosis. We present a case in which nephrologists performed this examination promptly allowing a timely diagnosis and treatment plan.

RESUMO

BACKGROUND: Peritoneal dialysis (PD) has multiple advantages over other dialysis modalities. As a home-based therapy, it allows patients to keep their autonomy, avoid frequent hospital visits and carry on with their usual lifestyle. However, as a self-care therapy, dependency has been traditionally considered a contraindication. However, assistance to perform PD (asPD) can be provided regardless of the patient's age and the duration of such help. This paper is aimed at reporting on assisted PD use in a Spanish Center, and is the first report on asPD from this country. METHODS: We retrospectively reviewed the electronic medical records of all patients consecutively treated with PD between May 1997 and December 2020 in our PD Unit. Assisted PD was defined as PD treatment requiring the help of another person. On the basis of the duration of dependency, we divided our cohort into: Group 1: Patients totally dependent at the start of PD treatment; Group 2: self-care patients that developed total dependency during follow up; Group 3: patients who needed short-term PD assistance. Group 4, consisting of 175 self-care PD, served as the control group. RESULTS: Seventy-three percent of patients who required asPD did so during their follow up, showing that an important proportion of patients may require some help even if they were autonomous at the beginning of PD. Even for short time periods, asPD should be an option, as up to 44% of autonomous PD patients became dependent for different reasons over time. Spouses were the most frequent caregivers and absence or loss of caregiver was a main reason for switching to hemodialysis. Fourteen percent of the patients received asPD as palliative care, with clinical symptoms and perceived well-being as the main treatment goals, with adequate results. The need for support and the quality of life were periodically discussed by patients, family members and hospital staff. CONCLUSION: Assisted PD is a safe option for dependent patients, young or elderly, and may result less expensive for our healthcare system, even when caregivers receive a financial incentive.

RESUMO

There are a significant number of mechanical complications related the peritoneal dialysis (PD) catheter and early diagnosis is key. Between them, the spontaneous extrusion of the catheter is quite uncommon but it should be included among the possible complications of the technique, given that it can be related to frequent situations in PD patients like abdominal wall issues, past immunosuppression or PD fluid leakage. In 25 years our Unit had three cases, probably related to peritoneal fluid leakage, exit site infection and past steroid treatment. Careful examination of abdominal wall preimplantation, adequate break-in period to allow maturation and early detection of exit site infection to start treatment in a timely fashion could help to prevent this rare complication. The complete extrusion of the catheter does not preclude from continuing PD treatment.
