The kinetics of goat sperm is negatively affected after freezing in an extender including zinc oxide nanoparticles.

BACKGROUND: Nanotechnology can benefit livestock industries, especially through postharvest semen manipulation. Zinc oxide nanoparticles (Np-ZnO) are potentially an example. OBJECTIVE: To investigate how the addition of zinc oxide nanoparticles (Np-ZnO) affected the characteristics of post-thawed goat semen. MATERIALS AND METHODS: Seminal pools from four Saanen bucks were used. Semen was diluted in Tris-egg yolk extender, supplemented with Np-ZnO (0, 50, 100 or 200 ug/mL), frozen and stored in liquid nitrogen (-196 degree C), and thawed in a water bath (37 degree C / 30 s). Semen samples were evaluated for sperm kinetics by computer-assisted sperm analysis (CASA), and assessed for other functional properties by epifluorescence microscopy, such as plasma membrane integrity (PMi), acrosomal membrane integrity (ACi) and mitochondrial membrane potential (MMP). RESULTS: For total motility (TM), the group treated with 200 ug/mL Np-ZnO was superior to the control. In straight-line velocity (VSL), the control was better than the group containing 200 ug/mL of Np-ZnO. For average path velocity (VAP), the control was higher than with 100 ug/mL Np-ZnO. For linearity (LIN), the control was higher than with 200 µg/mL Np-ZnO. In straightness (STR), the control and 100 µg/mL Np-ZnO were higher than with 200 ug/mL Np-ZnO. In wobble (WOB), the control was better than the 50 µg/mL Np-ZnO treatment. In PMi, ACi and MMP no significant differences were found. CONCLUSION: The addition of Np-ZnO (200 ug/mL) to the goat semen freezing extender improved the total motility of cells, whilst negatively affecting sperm kinetics. https://doi.org/10.54680/fr24210110512.

Long-term outcome of retroperitoneoscopic partial versus total adrenalectomy in patients with Cushing's syndrome.

BACKGROUND: We analyze the long-term outcome of surgery for Cushing's syndrome (CS) and the influence of the extent of surgical resection on the duration of postoperative cortisone substitution. METHODS: One-hundred forty-one patients (129 female, 12 males; mean age: 45.7 ± 12.8 years) operated between January 2000 to June 2020 were included in the analysis. Patients suffered from manifest (124) or subclinical (17) CS due to benign unilateral adrenal neoplasia. All tumors were removed by the posterior retroperitoneoscopic approach. 105 patients had total (TA) and 36 partial (PA) adrenalectomies. All patients were discharged with ongoing corticosteroid supplementation therapy. RESULTS: Follow-up data could be obtained for 83 patients. Twenty-four (1 male, 23 females; mean age 42.3 years) underwent PA and 59 TA (6 males, 53 females; mean age 44.6 years). Mean follow-up time was 107 ± 68 months (range: 6-243 months). The median duration of postoperative corticosteroid therapy was 9.5 months after PA and 11 months after TA (p = 0.1). Significantly, more patients after total adrenalectomy required corticosteroid therapy for more than 24 months (25% vs. 4%; p = 0.03). Recurrent ipsilateral disease occurred in one case after partial adrenalectomy and was treated by completion adrenalectomy. A case of contralateral recurrence associated with subclinical Cushing's syndrome was observed after total adrenalectomy. CONCLUSIONS: The risk of local recurrence after partial adrenalectomy in CS is low. Cortical-sparing surgery may shorten corticosteroid supplementation therapy after surgery.

Adult ocular adnexal xanthogranulomatous disease associated with immunoglobulin G4-related disease: an unusual association.

Adult-onset xanthogranuloma (AOX) and immunoglobulin G4-related disease (IgG4-RD) are uncommon fibrosing conditions that may exhibit localized ocular manifestations and occasionally systemic symptoms. These conditions exhibit overlapping clinical and histological features, suggesting a potential correlation between them, although their exact relationship remains unclear. This paper presents the case of a black male patient exhibiting typical histological indications of both AOX and IgG4-RD. The patient responded positively to corticosteroid treatment.

Evaluation of guideline implementation for dispensing driving-impairing medicines by National Pharmacy Organizations.

Background: In 2004, the International Pharmaceutical Federation (FIP) adopted a Statement of Professional Standard on the supply of medicines affecting driving performance, transformed to FIP guidelines in 2014. In 2011, the final report from the European initiative on Driving Under the Influence of Drugs, Alcohol and Medicines (DRUID) was published. Both documents provided recommendations for improving dispensing guidelines for driving-impairing medicines for patients who use psychoactive medicines. Objective: This study investigated the extent that European professional organizations of pharmacists (POPs) implemented existing guidelines and DRUID results. Methods: An online questionnaire survey was conducted in April-May 2022. Questionnaires were sent by e-mail to POPs in 46 European countries. The questionnaire addressed the following topics: awareness of FIP guidelines and DRUID outcomes (a), development of dispensing guidelines (b), target groups for information materials (c), evaluations of dispensing practices (d), examples of projects on medicines affecting driving fitness (e), development of ICT (Information and Communication Technology) -support (f), collaboration with organizations of physicians (g), and patients (h). The data were analyzed by indicating implementation initiatives in different countries. Open-ended questions were assessed qualitatively. Results: POPs in 23 European countries responded to the invitation (response rate: 50%). Guidelines for improving dispensing practices were available in 5 countries targeted at professionals, patients, and the general population. Patient and physician organizations were involved in 4 and 3 countries, respectively. Implementation was supported by computerized dispensing systems (5 countries) and public campaigns (5 countries). Conclusions: Twenty years after the introduction of FIP guidelines and ten years after the DRUID outcomes, only 5 European POPs have implemented this knowledge. Different activities were performed to support implementation, resulting in examples of successful use of recommendations for driving-impairing medicines in pharmacy practice. Implementation needs further attention. The successful practices that have been developed are an example for dissemination to other countries.

Diagnosis and treatment of interstitial lung disease related to systemic autoimmune myopathies: a narrative review.

Systemic autoimmune myopathies (SAMs) are rare diseases that lead to muscle inflammation and may be associated with a variety of systemic manifestations. Although there is great heterogeneity in the spectrum of extra-muscular involvement in SAMs, interstitial lung disease (ILD) is the most frequent lung manifestation. SAM-related ILD (SAM-ILD) presents significant variations according to geographic location and temporal trends and is associated with increased morbidity and mortality. Several myositis autoantibodies have been discovered over the last decades, including antibodies targeting aminoacyl-tRNA synthetase enzymes, which are associated with a variable risk of developing ILD and a myriad of other clinical features. In this review, the most relevant topics regarding clinical manifestations, risk factors, diagnostic tests, autoantibodies, treatment, and prognosis of SAM-ILD are highlighted. We searched PubMed for relevant articles published in English, Portuguese, or Spanish from January 2002 to September 2022. The most common SAM-ILD patterns are nonspecific interstitial pneumonia and organizing pneumonia. The combination of clinical, functional, laboratory, and tomographic features is usually sufficient for diagnostic confirmation, without the need for additional invasive methods. Glucocorticoids remain the first-line treatment for SAM-ILD, although other traditional immunosuppressants, such as azathioprine, mycophenolate, and cyclophosphamide have demonstrated some efficacy and, therefore, have an important role as steroid-sparing agents.

Phytotoxicity of organic extracts of five medicinal plants of the Neotropical savanna.

Medicinal plants produce a high diversity of secondary metabolites with different biological activities, which are commonly evaluated when prospecting for bioherbicides. We analyzed the phytotoxic activity of organic extracts from the leaves of five medicinal species, Byrsonima intermedia, Moquiniastrum polymorphum, Luehea candicans, Miconia chamissois, and Qualea cordata. Phytotoxicity was evaluated on the initial growth of cucumber seedlings through tests with different concentrations of hexane, ethyl acetate, and methanol extracts. The results showed that all organic extracts and all concentrations affected cucumber development, with methanol extracts generally showing the greatest negative effect on the initial growth of the target species. The only exception was for M. chamissois extracts, in which the hexane extract had the greatest phytotoxicity. Furthermore, the organic extracts were subjected to preliminary phytochemical analysis, revealing the widespread presence of alkaloids along with other chemical classes. All the study species are thus potential candidates for use as natural herbicides.

Pre-emergent indaziflam can enhance forest seed germination in direct seeding?

Pre-emergent herbicides can contribute to the control of weed competition in direct seeding restoration, however it is necessary to evaluate their effects on seeds of native tropical forest species. The aim of the study was to assess the potential impact of the herbicide indaziflam on the germination of 17 forest species. For this, a dosage of 180 mL of the product in 200L of water was compared to the control without herbicide. The degree of sensitivity of each species was calculated by a ratio between the percentage of germination with herbicide (GH) and the control without herbicide (GC) classifying them as: extremely sensitive (ES= (GH/GC) <0.25), sensitive (S=0.25< (GH/GC) <0.50), low sensitivity (LS=0.50< (GH/GC) <0.75), indifferent (I=0.75< (GH/GC) <1.0) and potentiated (P= (GH/GC) >1). The herbicide promoted a significant reduction in mean germination in 35% (n=6) of the species and 59% (n = 10) were sensitive or extremely sensitive to indaziflam, and only three did not germinate. On the other hand, 29.4% (n=5) showed low sensitivity or indifference to the herbicide, while seed germination was slightly increased by indaziflam to 11.7% (n=2). Pre-emergent indaziflam can be recommended in direct seeding restoration, as only 17.6% (n=3) of the species were inhibited by pre-emergent. However, the effect of indaziflam varies by species and requires further studies to support large-scale use in direct seeding.

Quiste hidatídico de la glándula tiroides: Reporte de tres casos

Introducción: La enfermedad hidatídica puede desarrollarse en cualquier órgano del cuerpo, siendo las localizaciones más frecuentes el hígado y pulmón, pero ocasionalmente puede afectar a otros órganos como la glándula tiroides. En Chile existen escasas publicaciones previas. El objetivo de este reporte es presentar el diagnóstico, tratamiento y seguimiento de tres pacientes portadores de quiste hidatídico de la glándula tiroides. Casos Clínicos: Se refiere a dos mujeres de 9 y 56 años y un paciente de sexo masculino de 56 años, provenientes de la zona rural de la Región de Aysén en la Patagonia, todos enviados por aumento de volumen sintomático de la glándula tiroides. El diagnóstico presuntivo se realizó mediante los antecedentes anamnésticos e imágenes de ultrasonografía. Todos fueron sometidos a tiroidectomía subtotal y a quimioprofilaxis post operatoria con Albendazol por 30 días. La confirmación diagnóstica se realizó mediante el estudio histopatológico. Ninguno ha presentado recurrencia, llevando una de ellas 22 años de seguimiento. Conclusión: Aunque la glándula tiroides rara vez se ve afectada, la enfermedad hidatídica no debe pasarse por alto en el diagnóstico diferencial de lesiones quísticas de la glándula, especialmente en pacientes que viven en regiones donde la enfermedad es endémica.

Introduction: Hydatid disease can develop in any organ of the body, the most frequent locations being the liver and lung, but occasionally it can affect other organs such as the thyroid gland. In Chile there are few previous publications. Aim: The aim of this report is to present the diagnosis, treatment and follow-up of three patients with hydatid thyroid cysts. Clinical Cases: Two women, ages 9 and 56, and a 56 year old male patient, referred from Aysén in Patagonia, all of them due to a symptomatic increased volume in thyroid gland. The diagnosis was made through anamnestic history and ultrasound images. All underwent subtotal thyroidectomy and postoperative chemoprophylaxis with Albendazole for 30 days. Diagnostic confirmation was made by histopathological study. None had recurrence, one of them has been followed for 22 years. Conclusion: In conclusion, although the thyroid gland is rarely affected, hydatid disease should not be overlooked in the differential diagnosis of cystic lesions of the thyroid gland, especially in patients living in regions where the disease is endemic.

[Comparison of tiapride and topiramate in the prophylactic treatment of chronic migraine: a randomised, double-blind, pilot study]. / Comparación de la tiaprida y el topiramato en el tratamiento profiláctico de la migraña crónica: estudio piloto, aleatorizado y doble ciego.

AIM: The aim of this study was to evaluate the efficacy and safety of tiapride compared to topiramate as a prophylactic in chronic migraine. PATIENTS AND METHODS: The study was conducted under randomised and double blind conditions. A total of 56 patients aged 18-65 years with chronic migraine were assigned to two treatment arms: tiapride, 100 mg twice daily, or topiramate, 25 mg twice daily, for 12 weeks. The primary endpoint was the change in the monthly average number of migraine days. In addition, measurements were performed to determine the change in the monthly number of headache days, the percentage of subjects with >50% and >75% decrease in their monthly migraine days, and the change in headache impact as measured by the Headache Impact Test-6. RESULTS: The intention-to-treat population included 39 subjects (tiapride = 21; topiramate = 18), 35 of whom (tiapride = 18; topiramate = 16) completed the trial. The tiapride group had a mean reduction of 7.2 ± 7.5 migraine days per month compared to 7.6 ± 5.8 for the topiramate group (p = 0.86). As with the other efficacy variables measured, no differences were found between the two groups. Adverse side effects were mild in both groups. CONCLUSION: In patients with chronic migraine, tiapride was found to be an effective, safe and well-tolerated prophylactic treatment when compared to topiramate.

TITLE: Comparación de la tiaprida y el topiramato en el tratamiento profiláctico de la migraña crónica: estudio piloto, aleatorizado y doble ciego.Objetivo. Evaluar la eficacia y la seguridad de la tiaprida en comparación con el topiramato en la profilaxis de la migraña crónica. Pacientes y métodos. Es un estudio aleatorizado y doble ciego. Un total de 56 pacientes de 18 a 65 años con migraña crónica fueron asignados a dos brazos de tratamiento: tiaprida, 100 mg dos veces al día, o topiramato, 25 mg dos veces al día, durante 12 semanas. El criterio de valoración principal fue el cambio en el promedio mensual de días de migraña. Además, se midió el cambio en el número mensual de días de cefalea, el porcentaje de sujetos con disminución > 50% y > 75% de sus días de migraña mensual, y el cambio del impacto de la cefalea medido por el Headache Impact Test-6. Resultados. La población por intención de tratar incluyó a 39 sujetos (tiaprida = 21; topiramato = 18) y completaron el ensayo 35 participantes (tiaprida = 18; topiramato = 16). El grupo con tiaprida tuvo una reducción media de 7,2 ± 7,5 días con migrañas por mes en comparación con 7,6 ± 5,8 para el grupo con topiramato (p = 0,86). Al igual que en las otras variables de eficacia medidas, no hubo diferencias significativas entre ambos grupos. Los efectos adversos fueron leves en ambos grupos. Conclusión. En pacientes con migraña crónica, la tiaprida demostró ser un tratamiento profiláctico eficaz, seguro y bien tolerado, al compararla con el topiramato.

Being in a crowd bonds people via physiological synchrony.

Collective events can generate intense emotions, shape group identities, and forge strong bonds. Do these effects extend to remote participation, and what are the psychological mechanisms underpinning their social power? We monitored psycho-physiological activity among groups of basketball fans who either attended games in-person (in a stadium) or watched games live on television in small groups. In-person attendance was associated with greater synchronicity in autonomic nervous system activation at the group level, which resulted in more transformative experiences and contributed to stronger identity fusion. Our findings suggest that the social effects of sports depend substantially on the inter-personal dynamics unfolding among fans, rather than being prompted simply by watching the game itself. Given the increasing prevalence of virtual experiences, this has potentially wide-reaching implications for many domains of collective human interaction.

Videolaryngoscopy vs. direct Macintosh laryngoscopy in tracheal intubation in adults: a ranking systematic review and network meta-analysis.

Videolaryngoscopes are thought to improve glottic view and facilitate tracheal intubation compared with the Macintosh direct laryngoscope. However, we currently do not know which one would be the best choice in most patients undergoing anaesthesia. We designed this systematic review with network meta-analyses to rank the different videolaryngoscopes and the Macintosh direct laryngoscope. We conducted searches in PubMed and a further five databases on 11 January 2021. We included randomised clinical trials with patients aged ≥16 years, comparing different videolaryngoscopes, or videolaryngoscopes with the Macintosh direct laryngoscope for the outcomes: failed intubation; failed first intubation attempt; failed intubation within two attempts; difficult intubation; percentage of glottic opening seen; difficult laryngoscopy; and time needed for intubation. We assessed the quality of evidence according to GRADE recommendations and included 179 studies in the meta-analyses. The C-MAC and C-MAC D-Blade were top ranked for avoiding failed intubation, but we did not find statistically significant differences between any two distinct videolaryngoscopes for this outcome. Further, the C-MAC D-Blade performed significantly better than the C-MAC Macintosh blade for difficult laryngoscopy. We found statistically significant differences between the laryngoscopes for time to intubation, but these differences were not considered clinically relevant. The evidence was judged as of low or very low quality overall. In conclusion, different videolaryngoscopes have differential intubation performance and some may be currently preferred among the available devices. Furthermore, videolaryngoscopes and the Macintosh direct laryngoscope may be considered clinically equivalent for the time taken for tracheal intubation. However, despite the rankings from our analyses, the current available evidence is not sufficient to ensure significant superiority of one device or a small set of them over the others for our intubation-related outcomes.

Manejo quirúrgico de la hidatidosis hepática en esta última década: ¿qué hemos aprendido? / Surgical management of liver hydatidosis in the last decade: what have we learned?

Resumen El manejo clínico de la hidatidosis hepática es complejo y se basa fundamentalmente en tres pilares: quirúrgico, percutáneo y farmacológico; los cuales en ocasiones pueden ser complementarios. La terapia debe definirse en función de las características, ubicación y tipo de quiste; a lo cual debe sumarse la experiencia del equipo médico, recursos disponibles y la adherencia de los pacientes al monitoreo a largo plazo. La cirugía es el tratamiento más utilizado, las técnicas percutáneas posiblemente puedan reemplazar a la cirugía en casos específicos. Sin embargo, a pesar de los avances en las técnicas quirúrgicas, en el uso de la quimioterapia y otros tratamientos, el manejo de hidatidosis hepática sigue siendo un problema importante, debido principalmente a la falta de consenso sobre qué procedimiento a utilizar es mejor. El objetivo de esta presentación es dar a conocer el amplio abanico de terapias existentes en el actual manejo de la hidatidosis hepática, así como indicar algunas sugerencias en la utilización de cada una de ellas.

The clinical management of hepatic hydatidosis is complex and is fundamentally based on three pillars: surgical, percutaneous and pharmacological; which can sometimes be complementary. Therapy should be defined based on the characteristics, location and type of cyst; to which must be added the experience of the medical team, available resources and the adherence of patients to long-term monitoring. Surgery is the most used treatment, percutaneous techniques can possibly replace surgery in specific cases. However, despite advances in surgical techniques, in the use of chemotherapy and other treatments, the management of liver hydatidosis continues to be a major problem; mainly due to the lack of consensus on which procedure to use is better. The objective of this presentation is to present the wide range of existing therapies in the current management of hepatic hydatidosis and some suggestions in the use of each one of them.

Guidelines for clinical trials of frontal fibrosing alopecia: consensus recommendations from the International FFA Cooperative Group (IFFACG).

BACKGROUND: Frontal fibrosing alopecia (FFA) has become one of the most common causes of cicatricial alopecia worldwide. However, there is a lack of clear aetiology and robust clinical trial evidence for the efficacy and safety of agents currently used for treatment. OBJECTIVES: To enable data to be collected worldwide on FFA using common criteria and assessment methods. METHODS: A multicentre, international group of experts in hair loss was convened by email to create consensus recommendations for clinical trials. Consensus was defined at > 90% agreement on each recommended part of these guidelines. RESULTS: Standardized diagnostic criteria, severity rating, staging, and investigator and patient assessment of scalp hair loss and other clinical features of FFA were created. CONCLUSIONS: These guidelines should allow the collection of reliable aggregate data on FFA and advance efforts in both clinical and basic research to close knowledge gaps in this condition.

The potential of FT-IR spectroscopy for improving healthcare in sepsis - An animal model study.

Fourier Transform-Infrared (FT-IR) absorption spectroscopy has been used to investigate pathophysiological changes caused by sepsis. Sepsis has been defined as a potentially fatal organic dysfunction caused by a dysregulated host response to infection and can lead a patient to risk of death. This study used samples consisting of the blood plasma of mice which were induced to sepsis state, compared to a healthy group using FT-IR associated with attenuated total reflectance (ATR) spectroscopy. For statistical analysis, principal components analysis (PCA) and linear discriminant analysis (LDA) were applied, independently, to the second derivative spectra of both the fingerprint (900-1800 cm-1) and the high wavenumber (2800-3100 cm-1) regions. The technique efficiently differentiated the blood plasma of the two groups, sepsis and healthy mice, the analysis indicating that fatty acids and lipids in the blood samples could be an important biomarker of sepsis.

Manejo complicaciones biliares de la cirugía del quiste hidatídico hepático / Management of biliary complications of liver hydatid cyst surgery

Resumen La complicación más frecuente del quiste hidatídico hepático es la fístula biliar externa. El diagnóstico pre e intraoperatorio es esencial en el tratamiento. En dicha evaluación se describen factores predictivos que hacen sospechar las comunicaciones cistobiliares. En presencia de estas, es posible realizar estudios adicionales para su diagnóstico. La filtración y la fístula biliar son las complicaciones postoperatorias más frecuentes y las principales causas de morbimortalidad. Sus tasas pueden disminuirse siguiendo con acuciosidad los factores predictivos y el adecuado manejo de la fístula biliar postoperatoria.

The most frequent complication of hepatic hydatid cyst is the external biliary fistula. Pre and intraoperative diagnosis is essential in treatment. This evaluation describes predictive factors that make cystobiliary communications suspicious. In the presence of these it is possible to carry out additional studies for its diagnosis. Filtration and biliary fistula are the most frequent postoperative complications and the main causes of morbidity and mortality. Their rates can be decreased by acutely following the predictive factors and proper management of postoperative biliary fistula.

The clinical manifestations at the onset of antisynthetase syndrome: A chameleon with multiple faces.

The antisynthetase syndrome (ASS) is clinically characterized by fever, myositis, interstitial lung disease, joint involvement, mechanic's hands, or Raynaud's phenomenon, and the presence of antisynthetase autoantibodies. These clinical manifestations may not occur simultaneously. Therefore, the aim of this study was to analyze the sequence in which these clinical manifestations can develop at the onset of ASS. This retrospective, single-center cohort study enrolled 55 ASS patients. Their mean age at the onset of ASS symptoms was 42.3±11.8 years. There was a predominance of female patients (75.9%) and white patients (72.7%). At initial presentation, 41.8% of the patients had fever, 43.6% had joint symptoms, 38.2% had myositis, 36.4% had interstitial lung disease, 18.2% had Raynaud's phenomenon, and 16.4% had mechanic's hands. Subsequent clinical symptoms emerged at varying time points. In two out of 55 cases, joint, muscle, and lung manifestations developed simultaneously. The median time between the onset of symptoms and the complete ASS clinical manifestation was 19.9 (4.0-60.2) months; whereas, the timeframe between the onset of symptoms and the ASS diagnosis was 29.0 (11.0-63.0) months. The confounding misdiagnoses interfering with the initial diagnosis were polymyositis (52.7%), dermatomyositis (29.1%), nonspecific interstitial pneumopathy (23.6%), rheumatoid arthritis (18.2%), and others (10.9%). Clinical features at the onset of ASS are highly variable. Consequently, confounding factors can lead to significant delays for the final and definitive diagnosis of ASS. Therefore, ASS should be considered a differential diagnosis in patients with initial symptoms of joint, lung, and/or muscle involvements, as well as fever, mechanic's hands, and/or Raynaud's phenomenon manifestations.

Change in renal function post-nephrectomy for renal cell carcinoma in patients with and without hypertension and/or diabetes.

BACKGROUND: The standard of care for surgically resectable disease renal cell carcinoma (RCC) is a nephrectomy. Post-nephrectomy, these patients are at risk for the development of new onset chronic kidney disease or the progression of pre-existing chronic kidney disease. We aimed to report the changes in renal function in patients who had a nephrectomy for RCC. METHODS: This retrospective, descriptive, cross-sectional study identified 137 patients who had a nephrectomy for RCC from 1 January 2009 to 31 December 2017. The pre-nephrectomy and post-nephrectomy estimated glomerular filtration rate (eGFR) and the histological subtype of RCC on histopathological analysis of the resected specimen were recorded from the National Health Laboratory Services online results platform. All analyses were conducted using SPSS (Version 25) and the significance level was set at p < 0.05. RESULTS: After a mean follow-up period of 26.5 ± 22 months (median = 19 months), the patients' eGFR dropped by a mean of 4.82 ± 8.67 ml/min/1.73 m2 (95% CI 3.23-6.41) post-nephrectomy. The mean eGFR fall in patients' who had hypertension and/or diabetes (n = 63) was significantly larger compared to patients who had neither of these comorbidities (n = 54; p < .001; mean = 7.30 ± 8.40 ml/min/1.73 m2 (95% CI 5.19-9.42) and 1.93 ± 8.14 ml/min/1.73 m2 (95% CI 0.30-4.15) respectively. CONCLUSIONS: The decline in renal function in patients with hypertension and/or diabetes mellitus is more pronounced than in patients with neither of these comorbidities. In these high-risk patients, measures must be taken to prevent the development and limit the progression of chronic kidney disease.
