Published: January 2021

Background Intralesional immunotherapy using different types of antigens is considered an effective and safe treatment option for different types of warts. However, there are few studies that illustrate the use of these antigens in the treatment of periungual warts as a distinct type of warts. Objective To evaluate the efficacy and safety of three antigens: measles, mumps, rubella (MMR) vaccine, Candida antigen, and purified protein derivative (PPD) in the treatment of periungual warts. Methods The study included 150 patients who were randomly assigned to 3 groups with 50 patients in each. Each agent was injected intralesionally at a dose of 0.1 mL into the largest wart at 2-week intervals until complete clearance or for a maximum of 5 sessions. Results Complete clearance of warts was observed in 70%, 80%, and 74% in PPD, Candida antigen, and MMR vaccine groups, respectively. There was no statistically significant difference regarding the therapeutic response between the 3 studied groups. Adverse effects were transient and insignificant in the 3 groups. No recurrence of the lesions was reported in any of the studied groups. Conclusions Intralesional antigen immunotherapy seems to be an effective therapeutic option for the treatment of periungual warts.

Background: The Oxford Big Data Institute, multiple sclerosis (MS) physicians and Novartis aim to address unresolved questions in MS with a novel comprehensive clinical trial data set. Objective: The objective of this study is to describe the Novartis–Oxford MS (NO.MS) data set and to explore the relationships between age, disease activity and disease worsening across MS phenotypes. Methods: We report key characteristics of NO.MS. We modelled MS lesion formation, relapse frequency, brain volume change and disability worsening cross-sectionally, as a function of patients’ baseline age, using phase III study data (≈8000 patients). Results: NO.MS contains data of ≈35,000 patients (>200,000 brain images from ≈10,000 patients), with >10 years follow-up. (1) Focal disease activity is highest in paediatric patients and decreases with age, (2) brain volume loss is similar across age and phenotypes and (3) the youngest patients have the lowest likelihood (<25%) of disability worsening over 2 years while risk is higher (25%–75%) in older, disabled or progressive MS patients. Young patients benefit most from treatment. Conclusion: NO.MS will illuminate questions related to MS characterisation, progression and prognosis. Age modulates relapse frequency and, thus, the phenotypic presentation of MS. Disease worsening across all phenotypes is mediated by age and appears to some extent be independent from new focal inflammatory activity.

Background: Long noncoding RNAs have been demonstrated to play important roles in different kinds of human malignancy. The purpose of this study was to evaluate the diagnostic and prognostic value of long intergenic non-protein coding RNA 1232 (LINC01232) in patients with pancreatic adenocarcinoma (PAAD) and further explore the clinical significance of the potential miRNAs that might be sponged by LINC01232. Methods: The potential target miRNAs that might be sponged by LINC01232 were analyzed using bioinformatics analysis. The Real-Time quantitative PCR was adopted to measure the relative expression of LINC01232 and target miRNAs in PAAD serum and tissue samples. The diagnostic and prognostic value of LINC01232 was evaluated using the receiver operating characteristic analysis and Kaplan-Meier survival analysis, respectively. Results: LINC01232 expression was upregulated in PAAD serum and tissues and associated with patients’ TNM stage. Serum LINC01232 expression had diagnostic value, and the high levels of LINC01232 could predict unfavorable prognosis in PAAD patients. miR-204-5p, miR-370-5p and miR-654-3p were proposed as 3 targets of LINC01232 in PAAD, and their decreased expression levels in PAAD patients showed certain clinical significance in diagnosis and prognosis. Conclusion: The data of this study revealed that LINC01232 expression is upregulated in PAAD serum and tissue samples with considerable diagnostic and prognostic significance. In addition, miR-204-5p, miR-370-5p and miR-654-3p may be sponged by LINC01232 in PAAD, which also show potencies in PAAD diagnosis and prognosis.

Published: January 2021

Background The efficacy and safety of direct oral anticoagulants (DOACs) in patients with peripheral arterial disease are not completely understood. Therefore, we conducted a meta-analysis to explore the effects of DOACs in this population. Methods We systematically searched the PubMed, Cochrane Library, and Web of Science till April 2020 for relevant randomized controlled trials and observational studies, with no linguistic restrictions. The efficacy outcomes were cardiovascular death, stroke, myocardial infraction, major adverse cardiovascular events (MACE), acute limb ischemia, amputation, and target lesion revascularization. The safety outcome was major bleeding events. Random effects risk ratios with 95% confidence intervals were calculated. Results A total four randomized controlled trials were included in this meta-analysis. Among peripheral arterial disease patients, DOACs did not reduce the risk of cardiovascular death (RR = 1.02 95%CI 0.75–1.37, P = 0.92), stroke (RR = 0.73 95%CI 0.46–1.14, P = 0.16), myocardial infraction (RR = 0.85 95%CI 0.70–1.03, P = 0.10), MACE (RR = 0.73 95%CI 0.46–1.14, P = 0.16), or amputation (RR = 0.73 95%CI 0.46–1.14, P = 0.16) compared with control. However, DOACs were associated with reduction in acute limb ischemia (RR = 0.67 95%CI 0.55–0.80, P < 0.01) and target lesion revascularization (RR = 0.89 95%CI 0.81–0.99, P = 0.02) at the expense of major bleeding events (RR = 1.43 95%CI 1.16–1.77, P < 0.01) compared with control. Conclusions Based on current evidence, no significant difference in cardiovascular death, stroke, myocardial infraction, MACE, and amputation was found when DOACs were compared to antiplatelet monotherapy. The benefits of preventing target lesion revascularization and acute limb ischemia were balanced by amplified risk of major bleeding. Larger randomized controlled trials are needed to figure out the uncertainty around efficacy and safety of medications for peripheral arterial disease.
Food autonomy: decolonial perspectives for Indigenous health and buen vivir
Authors: Calderón Farfán Juan Camilo , Dussán Chaux Juan David , Arias Torres Dolly 
Published: January 2021

Introduction: Indigenous peoples’ food systems have weakened as a result of pressures exerted by agro-commercial policies and chains, which has led to the dependency and deterioration of their ways of life. It is in this context that the construction of perspectives on food autonomy positions itself as a potential and strategic field of social decolonial mobilization for indigenous peoples’ health and buen vivir. Objective: The aim of this study was to analyze the meanings of food autonomy from the perspectives of a Nasa Indigenous community in Colombia. Method: This was a qualitative study, involving 38 Indigenous people belonging to the Nasa Huila Indigenous community, aged between 18 and 73, with different occupations. The information was obtained by means of discussion groups and processed through content analysis. The project had the consent and ethical endorsement of the indigenous community. Results: According to the study group, food autonomy is related to the Nasa identity, today weakened by territorial conditions, proximity to non-indigenous populations and the external influence of institutional food programs. Food autonomy develops by means of practices aimed at the production, distribution, preparation and consumption of healthy, chemical-free, homegrown food products from the family level, for self-consumption and in resistance to dependence on external commercial chains. Conclusion: Food autonomy positions itself as a community and political strategy that integrates the strengthening of family gardens, the adaptation of a food program menu, education and governance towards the development of autonomous processes from a decolonial perspective, for the promotion of health and buen vivir.
Development of alternating, ipsilateral Horner syndrome and Pourfour du Petit syndrome associated with oesophagostomy tube placement in a cat
Authors: Lee Liu Yi , Horikawa Taemi 
Published: January 2021

Case summary A 12-year-old spayed female domestic shorthair cat was presented to a referral hospital for chronic intermittent hyporexia and weight loss. An abdominal ultrasound was performed, which revealed a mid-jejunal mass and mesenteric lymphadenomegaly. Surgical resection and placement of an oesophagostomy tube (O-tube) was performed. Upon recovery the cat exhibited signs of Horner syndrome, which resolved over the span of 2 weeks. Subsequently, the cat developed signs of unilateral Pourfour du Petit syndrome in the left eye at day 20 and unilateral Horner syndrome at day 25 ipsilateral to the O-tube insertion site. The O-tube was removed 32 days postoperatively, and Horner syndrome resolved 24 h later. Follow-up examination 15 months later did not show any recurrence of ocular signs. Relevance and novel information To our knowledge, this represents the first report of alternating ipsilateral Horner and Pourfour du Petit syndrome in a single patient that underwent placement of an O-tube. Neurological complications after O-tube placement are uncommon, with only a single previously published report of a cat developing Horner syndrome after O-tube placement. Veterinarians should consider potential ocular and neurological complications after O-tube placement and monitor for such signs postoperatively.

Background Iodine deficiency is a major public health concern throughout the world. Goiter is the most visible sign of iodine deficiency. In Ethiopia, a study finding regarding the prevalence of goiter among school-age children is inconsistent and highly variable. Objectives To estimate the pooled prevalence of goiter among school-age children in Ethiopia. Methods Three international databases (MEDLINE/Pub-Med, Google Scholar and Science Direct) were systematically searched. Besides, the reference sections of identified articles were searched to increase the chance of detecting missed articles in gray literature. STATA Version 14 statistical software was used to conduct a meta-analysis. The pooled prevalence with a 95% confidence interval was displayed using the forest plot. A random-effect meta-analysis model was used to compute the pooled prevalence, and The Cochrane Q test statistics and I2 test were used to assess the heterogeneity of the studies. Results A total of 14 studies fulfilled the inclusion criteria and included in this systematic review and Meta-analysis, with a total sample size of 26,282. The finding of this systematic review revealed that the pooled prevalence of goiter among school-age children was 42.9% (95% CI: 38.8–46.9). The highest prevalence of goiter (46.7%) was observed in Oromia region and the lowest (26.3%) was observed in Benishangul-Gumuz region. Conclusions This review finding revealed that more than two in five of the school children in Ethiopia suffer from iodine deficiency disorder as manifested by the goiter rate.

Study Design: A retrospective observational study. Objective: To clarify the association of the paraspinal muscle area and composition with clinical features in patients with cervical ossification of the posterior longitudinal ligament (OPLL). Methods: Consecutive patients with cervical OPLL who underwent cervical magnetic resonance imaging (MRI) before surgery were reviewed. The cross-sectional area (CSA) and fatty infiltration ratio (FI%) of deep posterior cervical paraspinal muscles (multifidus [MF] and semispinalis cervicis [SCer]) were examined. We assessed the association of paraspinal muscle measurements with the clinical characteristics and clinical outcomes, such as Neck Disability Index (NDI) score. Moreover, we divided the patients into 2 groups according to the extent of the ossified lesion (segmental and localized [OPLL-SL] and continuous and mixed [OPLL-CM] groups) and compared these variables between the 2 groups. Results: 49 patients with cervical OPLL were enrolled in this study. The FI% of the paraspinal muscles was significantly associated with the number of vertebrae ( ρ = 0.283, p = 0.049) or maximum occupancy ratio of OPLL ( ρ = 0.397, p = 0.005). The comparative study results indicated that the NDI score was significantly worse (OPLL-SL, 22.9 ± 13.7 vs. OPLL-CM, 34.4 ± 13.7) and FI% of SCer higher (OPLL-SL, 9.1 ± 1.7% vs. OPLL-CM, 11.1 ± 3.7%) in the OPLL-CM group than those in the OPLL-SL group. Conclusions: Our results suggest that OPLL severity may be associated with fatty infiltration of deep posterior cervical paraspinal muscles, which could affect neck disability in patients with cervical OPLL.

Published: January 2021

Study Design: Prospective non-randomized single-center cohort study. Objectives: To analyze the quality of postoperative magnetic resonance imaging of 2 structurally different cervical disc arthroplasty devices at the index and adjacent levels. Methods: A non-randomized, comparative, prospective, single-center study included 40 patients (23 men and 17 women) aged 32 (26-40) years. Two study groups were utilized: in the first (n = 20), a titanium prosthesis was used; in the second (n = 20), a cobalt-chromium implant was used. Evaluation of MRI studies before and after surgery was performed using sagittal and axial T2 weighted images by 2 specialists who were blinded to the prosthesis that was used. To determine the quality of an MRI image, the classification of Jarvik 2000, the radiological and orthopedic scales for assessing artifacts were used. Results: There was good-to-excellent inter-observer agreement for all of the MR parameters used for the titanium and satisfactory-to-good for the cobalt chromium group. The analysis of the quality of postoperative imaging using the Jarvik 2000 scale showed a statistically significant deterioration in MR images in the cobalt chromium group ( P < 0.001), compared to the titanium ( P = 0.091). Following a single-level total arthroplasty, the titanium group had better MRI images according to radiological and orthopedic scales ( P < 0.001). Conclusion: Titanium cervical disc arthroplasty devices result in superior postoperative MR imaging, as compared to cobalt chromium prostheses, as the latter significantly reduces image quality due to the pronounced ferromagnetic effect.

Background: Lateral patellar dislocation can become a recurrent problem after the first episode. Identifying those patients who are at increased risk of redislocation is important for the treatment decision-making process. Purpose: To identify clinical and radiologic risk factors for recurrence of patellar dislocation after a first episode. Study Design: Case-control study; Level of evidence, 3. Methods: The study included patients with lateral patellar dislocation and a 1-year minimum follow-up who were seen between 2011 and 2018. Patients aged 10 to 65 years were included. Patient characteristics, physical examination (patellar apprehension, J sign), and radiographs were reviewed. The Caton-Deschamps and Insall-Salvati ratios were used to evaluate patella alta. High-grade trochlear dysplasia was defined as Dejour types B, C, and D. Results: A total of 130 patients (139 knees) with primary lateral patellar dislocation were included. Recurrent dislocation was seen in 83 knees (59.71%). Stepwise logistic regression analysis demonstrated that Caton-Deschamps ratio ≥1.15 (OR, 2.39; 95% CI, 1.09-5.22; P = .029), age <21 years (OR, 2.53; 95% CI, 1.11-5.77; P = .027), and high-grade trochlear dysplasia (OR, 4.17; 95% CI, 1.90-9.17; P < .001) were significantly associated with patellar redislocation. Based on the presence of these factors, the probability of dislocation after a first lateral patellar dislocation was 31.2% with no factors present, 36.6% with any 1 factor present, 71.7% with any 2 factors present, and 86.2% if all 3 conditions were present. Conclusion: The results of this study indicated that patella alta, high-grade trochlear dysplasia, and age <21 years were independent risk factors for patellar redislocation after a first episode, with an additive effect when they were present together. This may help to guide the type of treatment for these patients.

AbstractDue to the low prevalence of afibrinogenemia, epidemiologic data on afibrinogenemia are limited, and no data are available on health-related quality of life (HRQoL). We conducted a cross-sectional international study to characterize the clinical features, the fibrinogen supplementation modalities, and their impact on HRQoL in patients with afibrinogenemia. A total of 204 patients (119 adults and 85 children) from 25 countries were included. The bleeding phenotype was severe: 68 (33.3%) patients having at least one bleed per month and 48 (23%) a history of cerebral bleeding. About 35% (n = 72) of patients were treated with fibrinogen concentrates or cryoprecipitates as prophylaxis, 18.1% (n = 37) received ≥1 injection per week, and 16.6% (n = 34) were on home treatment. A thrombotic event was reported in venous and/or arterial territories by 37 (18.1%) patients. Thrombosis occurred even in young patients, and recurrence was frequent (7.4%). The total HRQoL was lower in children than in adults. Discomfort linked to treatment and limitations to sports and leisure were the main concerns. Women and children were particularly affected in family relationships. In multivariate analyses, younger age, residence in Asia or Africa, and a previous thrombotic event were statistically correlated with a worse HRQoL. In summary, our study underlines the severe bleeding and thrombotic phenotype and their impact on HRQoL in afibrinogenemia. The optimal strategy for fibrinogen supplementation needs to be determined. This trial was registered at www.clinicaltrials.gov as #NCT03484065.

Published: January 2021

BackgroundInvasive mechanical ventilation of hypoxaemic coronavirus disease 2019 (COVID-19) patients is associated with mortality rates of >50%. We evaluated clinical outcome data of two hospitals that agreed on a predefined protocol for restrictive use of invasive ventilation where the decision to intubate was based on the clinical presentation and oxygen content rather than on the degree of hypoxaemia.MethodData analysis was carried out of patients with positive PCR-testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), typical history, and symptoms and pulmonary infiltrates who exhibited oxygen saturation values of <93%.ResultsWe identified 78 patients who met the inclusion criteria. The oxygen saturation nadir was 84.4±6.5% for the whole group. 53 patients (68%) received nasal oxygen (group 1), 17 patients (22%) were treated with nasal high-flow continuous positive airway pressure (CPAP), noninvasive ventilation or a combination thereof (group 2), and eight patients (10%) were intubated (group 3). The Horovitz index was 216±8 for group 1, 157±13 for group 2 and 106±15 for group 3. Oxygen content was 14.5±2.5, 13.4±1.9 and 11.6±2.6 mL O2·dL−1for the three respective groups. Overall mortality was 7.7%; the mortality of intubated patients was 50%. Overall, 93% of patients could be discharged on room air.ConclusionPermissive hypoxaemia where decisions for the level of respiratory therapy were based on the clinical presentation and oxygen content resulted in low intubation rates, low overall mortality and a low number of patients who require oxygen after discharge.
