Direct anterior approach versus posterolateral approach in total hip arthroplasty: effects on early post-operative rehabilitation period.

Main surgical approaches to the hip have been modified during last decades, in an effort to reduce invasiveness of the surgical procedure and allow a faster rehabilitation. Direct anterior approach is the only approach, which does not require muscle detachment, thus theoretically leading to reduced post-operative pain and allows earlier recovery. The aim of this study was to report a comparison between patients operated with direct anterior approach and postero-lateral approach in terms of immediate post-operative and in-hospital records. Pain, operative time, intra- and post-operative complications, blood loss, hospitalization, motor component of the Functional Independence Measure (M-FIM), timed up and go (TUG) test were measured between the two groups and compared. Direct anterior approach showed better results in M-FIM, TUG, hospitalization and blood loss, without any significant difference for intra- and post-operative complications between the 2 groups. This study shows that early post-operative recovery is influenced by the chosen approach. Direct anterior approach showed better outcomes when compared to postero-lateral approach, limited to hospitalization, blood loss, and functional scores. Further comparisons are needed to evaluate direct anterior approach to maintain advantages over postero-lateral approach on longer follow-up period.

Prevalence of BRCA1 and BRCA2 mutations in unselected breast cancer patients from Peru.

The prevalence of BRCA1 and BRCA2 mutations among breast cancer patients in Peru has not yet been explored. We enrolled 266 women with breast cancer from a National cancer hospital in Lima, Peru, unselected for age or family history. DNA was screened with a panel of 114 recurrent Hispanic BRCA mutations (HISPANEL). Among the 266 cases, 13 deleterious mutations were identified (11 in BRCA1 and 2 in BRCA2), representing 5% of the total. The average age of breast cancer in the mutation-positive cases was 44 years. BRCA1 185delAG represented 7 of 11 mutations in BRCA1. Other mutations detected in BRCA1 included: two 2080delA, one 943ins10, and one 3878delTA. The BRCA2 3036del4 mutation was seen in two patients. Given the relatively low cost of the HISPANEL test, one should consider offering this test to all Peruvian women with breast or ovarian cancer.

Platelet lysate for the treatment of osteoarthritis: a systematic review of preclinical and clinical studies.

Intra-articular injection-based therapy is often used aside conservative treatment and lifestyle modifications to manage knee osteoarthritis (KO) patients. Conventional injections contain steroids and hyaluronic acid, while more recently multipotential adult stem cell, platelet-rich plasma (PRP), and platelet lysate (PL) injections have been used to promote cartilage regeneration or repair. The aim of the current study is to analyse current evidence on PL injections for the treatment of KO and to determine if these are effective and how these perform compared to other injection regimens. The databases of Scopus, Embase, PubMed, Web of Science, and Cochrane Library were searched on 30 June 2023. Risk of bias was assessed using the SYRCLE tool for animal studies and Cochrane RoB 2 as well as ROBINS-I tool for human studies. Studies were included if these were in English, any year, and regarded animals with osteoarthritis (OA) or human adult patients with OA. In vitro trials and non-adult human studies were excluded. Results on OA symptom stage and severity, and pain were recorded. The research retrieved three human studies (n = 48, n = 25, n = 58) and four animal studies: one rabbit, two studies, and one rat study. PL was found to decrease KO symptoms at follow-up ≤ 1 year with respect to baseline levels and when compared to hyaluronic acid or platelet-rich plasma. Symptoms returned 6 months-1 year after the final administration, with studies showing peak efficacy at approximately 6 months. Animal studies showed clinical improvements, reduction of lameness, and partial effect on the cartilage regeneration of the seven studies, two had a high risk of bias, four were associated to some concerns, and one had low risk. A major source of bias in these studies was the use of questionnaires and scoring that could be subject to interpretation. Overall, PL was well-tolerated and showed efficacy comparable to PRP; when pain control was assessed, it showed similar efficacy compared to hyaluronic acid. These findings may support its use in clinical trials to confirm these initial findings; future research should also focus on the comparison with other non-surgical treatments, on a more detail of the potential regenerative properties, and to optimise the treatment schedule.

[Correlation between demyelinating lesions and executive function decline in a sample of Mexican patients with multiple sclerosis]. / Correlación entre las lesiones desmielinizantes y el deterioro de las funciones ejecutivas en una muestra de pacientes Mexicanos con esclerosis múltiple.

BACKGROUND: Multiple Sclerosis (MS) is characterised by several neurological symptoms including cognitive impairment, which has recently been the subject of considerable study. At present, evidence pointing to a correlation between lesion characteristics and specific cognitive impairment is not conclusive. OBJECTIVE: To investigate the presence of a correlation between the characteristics of demyelinating lesions and performance of basic executive functions in a sample of MS patients. PATIENTS AND METHODS: We included 21 adult patients with scores of 0 to 5 on the Kurtzke scale and no exacerbations of the disease in at least 3 months prior to the evaluation date. They completed the Stroop test and the Wisconsin Card Sorting Test (WCST). The location of the lesions was determined using magnetic resonance imaging (MRI) performed by a blinded expert in neuroimaging. RESULTS: Demyelinating lesions were more frequently located in the frontal and occipital lobes. The Stroop test showed that as cognitive demand increased on each of the sections in the test, reaction time and number of errors increased. On the WCST, 33.33% of patients registered as having moderate cognitive impairment. No correlation could be found between demyelinating lesion characteristics (location, size, and number) and patients' scores on the tests. CONCLUSION: Explanations of the causes of cognitive impairment in MS should examine a variety of biological, psychological, and social factors instead of focusing solely on demyelinating lesions.

[Cerebellar infarction: prognosis and complications of vascular territories]. / Infarto cerebeloso: pronóstico y complicaciones de sus territorios vasculares.

INTRODUCTION: Cerebellar infarction (CI) is uncommon, but may result in severe complications. The aim of our study was to determine the characteristics of patients with CI, as well as their outcomes as regards the territories affected. PATIENTS AND METHODS: Data were collected from 124 patients admitted to our department during a five-year period, with a radiological diagnosis of CI, and with or without involvement of other brain territories. RESULTS: The mean age in our series was 65.2 years, with most being male (68.5%). The posterior inferior cerebellar artery (PICA) was the most commonly affected territory at 49.2%, followed by superior cerebellar artery (SCA) at 17.7%, and anterior inferior cerebellar artery (AICA) at 10.5%. There was simultaneous supratentorial involvement in 13.7%, and two or three cerebellar arteries involved in 8.9%. The main aetiology in PICA was atherothrombosis (P=.02). On the other hand, cardio-embolism was the main origin in cases with more than one affected territory (P=.04). No particular aetiology could be found in SCA and AICA. There was haemorrhagic transformation in 29 patients (23.4%), particularly in the PICA and when other territories were involved. There was hydrocephalus in 15 patients (12.1%, 12 of them PICA; P=.02) in 2.9 ± 1.5 days from stroke onset. At discharge, the degree of disability was worse if more than one arterial territory was involved (Rankin ≥ 3, 64% versus 31-36%; P=.05). Four (3.2%) patients died. CONCLUSIONS: CI is very heterogeneous. Nevertheless, it is noteworthy that PICA infarction is the most frequent type and its aetiology is usually atherothrombotic. Moreover, it is the territory most frequently associated with severe complications, which take place during the first week of the stroke.

[Benefit of therapeutic drug monitoring of immunosuppressants and immunomodulators in the management of autoimmune diseases]. / Intérêt des dosages pharmacologiques d'immunosuppresseurs et immunomodulateurs dans la prise en charge des maladies autoimmunes.

The pharmacokinetics of drugs, such as immunosuppressants, justify the need of measuring their blood concentrations in order to adjust their dosage. Therapeutic Drug Monitoring (TDM) of ciclosporin, tacrolimus and mycophenolate mofetil has shown its benefit particularly in the management of renal transplantees, in order to prevent graft rejection. When prescribed in autoimmune diseases, their pharmacokinetic variability and the variability of clinical response would justify TDM in practice. TDM may be useful in systemic lupus, for hydroxychloroquine, in order to monitor patient compliance. Despite insufficient data in the literature, for mycophenolate mofetil, TDM would permit to maintain clinical remission in adults and children with lupus nephritis, as well as in mucosal pemphigoid and idiopathic nephrotic syndrome in children. Studies are still necessary to validate the thresholds and TDM conditions. For azathioprine, TPMT phenotyping is recommended before prescription. For methotrexate, tacrolimus and ciclosporin, data are still sparse on the benefit of TDM, although it may improve tolerance to tacrolimus in lupus. Finally, for infliximab, in case of loss of response in maintenance, TDM may be proposed in parallel with detection of anti-drug antibodies.

High-dimensional profiling reveals Tc17 cell enrichment in active Crohn's disease and identifies a potentially targetable signature.

The immune-pathology in Crohn's disease is linked to dysregulated CD4+ T cell responses biased towards pathogenic TH17 cells. However, the role of CD8+ T cells able to produce IL-17 (Tc17 cells) remains unclear. Here we characterize the peripheral blood and intestinal tissue of Crohn's disease patients (n = 61) with flow and mass cytometry and reveal a strong increase of Tc17 cells in active disease, mainly due to induction of conventional T cells. Mass cytometry shows that Tc17 cells express a distinct immune signature (CD6high, CD39, CD69, PD-1, CD27low) which was validated in an independent patient cohort. This signature stratifies patients into groups with distinct flare-free survival associated with differential CD6 expression. Targeting of CD6 in vitro reduces IL-17, IFN-γ and TNF production. These results identify a distinct Tc17 cell population in Crohn's disease with proinflammatory features linked to disease activity. The Tc17 signature informs clinical outcomes and may guide personalized treatment decisions.

Measurement and control of plasma oscillations in femtosecond filaments.

The short-lived longitudinal plasma oscillations generated during filamentation in argon and nitrogen gas are measured with a specially designed current monitor. The magnitude and initial direction of the corresponding currents depend sensitively on laser polarization and nature of the gas. The results are interpreted as resulting from the competition between two forces acting on free electrons born during the filamentation process: the Lorentz laser force and a Coulomb wake force resulting from a lateral expansion of the plasma.

Nutritional status in a multicenter study among institutionalized patients in Spain.

INTRODUCTION: The aim of our study was to investigate and evaluate, in a multicenter study, the prevalence of malnutrition as well as the relationship between different anthropometric and biochemical markers with Mininutritional assessment (MNA) scores. SUBJECTS AND METHODS: A representative sample of the institutionalized Spanish population aged 65 and older (stricly speaking, born in 1942 or earlier), is covered in this cross-sectional survey. Anthropometric variables, MNA test and biochemical evaluation were performed by Geriatrics Units specialists. RESULTS: The percentage of patients classified as well nourished (27.8%) was larger in the 85-94 (39.4%) range than in the 65-74 (26.2%), 75-84 (24%) and > 95 (14.8%) age ranges. A population of 254 patients (49.6%) were at risk of undernutrition, a number which was larger in 75-84 (52%), 65-74 (53.8%) and > 95 (53.7%) than in the 85-94 (44.1%) ones. On the other hand, undernourishment (22.5%) was larger in those of 95 and older (31.5%) than in 85-94 (16.5%), 75-84 (24%) and 65-74 (20%) patients. According to our investigation females are worse nourished (Odd's Ratio 0.51 CI 95%: 0.33-0.79) and, consequently, more undernourished (Odd's Ratio 2.36 CI 95%: 1.48-3.74) than males. No significant differences in the "at risk of undernutrition category" (Odd's Ratio 0.76 CI 95%: 0.52-1.10) were observed but, in transferrin, iron, haemoglobin and total cholesterol, statistical differences among MNA classification were detected. MNA scores were correlated with iron, total cholesterol, albumin, transferrin, age and haemoglobin. CONCLUSION: In this multicenter study, institutionalized patients have a high prevalence of undernutrition or are at-risk, as well as females are more undernourished than males.

Acute symptomatic seizures and epilepsy after mechanical thrombectomy. A prospective long-term follow-up study.

INTRODUCTION: New treatments for acute ischaemic stroke, such as mechanical thrombectomy, can achieve reperfusion of large ischaemic tissue. Some studies have suggested that reperfusion therapies can increase the risk of suffering acute symptomatic seizure (ASS) and poststroke epilepsy (PSE). The aim of the study was to determine the incidence of ASS and PSE in patients undergoing thrombectomy, and related factors. PATIENTS AND METHODS: This was a retrospective single-centre study including patients with ischaemic stroke and NIHSS> 8 treated with thrombectomy with a follow-up ≥5 years. We evaluated several epidemiological, radiological, clinical and electroencephalographic variables. RESULTS: Of the 344 included patients, 21 (6.1%) presented ASS, 53 (15.40%) died in the acute phase, and 13 (4.46%) died during the first year. The degree of reperfusion (p 0.029), advanced age (p 0.035), and haemorrhagic transformation (p 0.038) increased the risk of suffering ASS, with degree of reperfusion being an independent factor, OR 2.02 (1.21-4.64). The incidence of PSE was 4.12% in the first year, 3.72% in the second, and 1.61% in the fifth. The accumulated incidence at 5 years was 8.93%. Related risk factor for suffering PSE was ASS (p < 0.001), yielding an OR value of 2.00 (1.28-3.145). CONCLUSIONS: Thrombectomy doesn´t increase the risk of ASS. A higher percentage of reperfusion, advanced age, and haemorrhagic transformation are associated with an increased risk of ASS. ASS is a risk factor for suffering PSE. In terms of mortality, having suffered ASS and/or PSE does not increase acute or long-term mortality.

Gastro-Laryngeal Tube for endoscopic retrograde cholangiopancreatography: a preliminary report.

The Gastro-Laryngeal Tube is a modification of the Laryngeal Tube that provides a dedicated channel for the insertion of a gastroscope. In this study of 30 patients undergoing general anaesthesia for endoscopic retrograde cholangiopancreatography, we evaluated both the effectiveness of airway management with a Gastro Laryngeal Tube and the feasibility of performing it using the endoscopic channel. The Gastro Laryngeal Tube was inserted successfully in all patients, in 27 patients at the first attempt. The mean (SD) time to achieve an effective airway was 26 (6) s. Mean (SD) inspiratory and expiratory tidal volumes were 336 (57) ml and 312 (72) ml, respectively, and oropharyngeal leak pressure was 33.7 (2) cmH(2)O. These data suggest that the Gastro Laryngeal Tube is an effective and secure device for airway management and for use during performance of endoscopic retrograde cholangiopancreatography.

Glycaemic control with liraglutide: the phase 3 trial programme.

AIMS: To review the efficacy and safety of liraglutide from the phase 3 trials, focusing primarily on glycaemic control. KEY FINDINGS: Liraglutide was shown to reduce glycated haemoglobin (HbA(1c) ) levels by up to 1.5% from baseline, significantly more than the comparators sitagliptin (-0.9%), glimepiride (-0.5%), rosiglitazone (-0.4%), insulin glargine (-1.1%) and exenatide (-0.8%). Both fasting plasma glucose (FPG) and postprandial plasma glucose (PPG) levels were shown to be significantly reduced from baseline [up to -2.4 mmol/l (-43.2 mg/dl) and -2.7 mmol/l (-48.6 mg/dl) for FPG and PPG in the liraglutide 1.8 mg group, respectively]. Changes in HbA(1c) , FPG and PPG levels were sustained for the duration of the studies (up to 52 weeks). The glycaemic control offered by liraglutide was not associated with an increased rate of minor hypoglycaemic events compared with comparator treatments, with rates significantly lower than those of glimepiride and exenatide. Major hypoglycaemic events were rare and only occurred in combination with a sulfonylurea. Nausea was the most frequent adverse event, but subsided within the first few weeks. CONCLUSIONS: Liraglutide has been shown to offer effective glycaemic control for patients with type 2 diabetes and is appropriate for use across the conventional continuum of care. Despite the sustained reductions in HbA(1c) , FPG and PPG levels achieved with liraglutide, rates of minor hypoglycaemia were generally low, although the risk increased when combined with a sulfonylurea. Liraglutide is therefore a promising new option for the treatment of type 2 diabetes.

Coulomb logarithm accuracy in a Yukawa potential.

We present a complete theory of the scattering of a particle in a Yukawa potential when the screening length is much larger than the classical impact parameter for 90^{∘} deflection and than the de Broglie length. The classical limit, the quantum limit, and the intermediate case are investigated, enabling an accurate determination of the argument of the Coulomb logarithm in the general case. The connection with previously published results is made.

Effectiveness of different supralottic airways during resuscitation manoeuvres. A systematic review. / Efectividad de la ventilación de los diversos dispositivos extraglóticos durante las maniobras de reanimación. Revisión sistemática.

INTRODUCTION: Supraglottic airways, which are easily inserted and minimize interruptions in cardiopulmonary resuscitation manoeuvres, are now widely used in pre- and in-hospital emergencies. However, most studies in these devices do not specify whether they ensure good ventilation during CPR. This systematic review aims to determine whether there is evidence that supraglotic airways enable effective ventilation during resuscitation. METHODS: The MEDLINE and COCHRANE databases were searched for studies published in English up to 30 November 2018. Eligible studies were all those that objectively evaluated tidal volume during resuscitation maneuvers in patients over 18 years of age using various supraglottic airways. RESULTS: A total of 3734 articles were identified, of which 252 were duplicates. Only 1 objectively evaluated ventilation during resuscitation maneuvers and presented data relevant to this review. The study included 470 patients, 51 of which underwent spirometry. Only 4.48% of patients survived to hospital discharge; however, the correlation with ventilation effectiveness was not assessed. CONCLUSION: There is no scientific evidence that supraglottic airways provide effective ventilation during resuscitation maneuvers. Evaluation by spirometry, chest impedance and ultrasound may help to determine the ventilatory efficacy of supraglottic airways during CPR, and clarify whether this factor contributes to the difficulties experienced in reversing cardiorespiratory arrest.

Spironolactone in Dermatology: Uses in Acne, Hidradenitis Suppurativa, Female Pattern Baldness, and Hirsutism. / Uso de la espironolactona en dermatología: acné, hidradenitis supurativa, alopecia femenina e hirsutismo.

Spironolactone is an economical potassium-sparing diuretic with an anti-androgenic effect and a good safety profile. Our experience suggests that this diuretic is underexploited in dermatology even though there is evidence supporting its use in several skin conditions. When prescribed for acne in female patients (level 1-2 evidence; strength of recommendation, B), for example, it can reduce the need for antibiotics and possibly isotretinoin. Other diseases in which spironolactone is potentially useful are hidradenitis suppurativa and female androgenetic alopecia. We discuss the indications for spironolactone, dosing in dermatology, precautions to consider, and adverse effects. We also review new evidence that stresses the safety of long-term therapy and supports the use of this drug without the need for complementary testing in young women. We think that spironolactone merits a place among the medications commonly used in routine clinical practice.

Juvenile Xanthogranuloma: An Entity With a Wide Clinical Spectrum. / Xantogranuloma juvenil: una entidad con amplio espectro clínico.

Juvenile xanthogranulomas (JXGs) are rare, benign lesions that belong to the large group of non-Langerhans cell histiocytoses. JXG presents with 1 or more erythematous or yellowish nodules that are usually located on the head or neck. Most JXG lesions are congenital or appear during the first year of life. Extracutaneous involvement is rare, but the literature traditionally suggests investigating the possibility of ocular compromise. JXG is mainly a clinical diagnosis, but a skin biopsy may sometimes be needed for confirmation. JXGs on the skin are self-limiting and usually do not require treatment. This review describes the clinical and therapeutic aspects of JXG, emphasizing available evidence and the diagnosis of extracutaneous involvement.
