Short- and long-term prognostic factors associated with functional recovery in elderly patients with hip fracture: A systematic review.

This systematic review aimed to identify short- and long-term associated factors to functional recovery of elderly hip fracture patients after discharge. We identified 43 studies reporting 74 associated factors to functional recovery; most of them were biological, sociodemographic, or inherent factors to patients' baseline characteristics, including their pre-facture functional capacity. PURPOSE: This systematic review aimed to identify short- and long-term associated factors to functional recovery of elderly hip fracture patients after hospital discharge. We assessed the use of the hip fracture core-set and key-performance indicators for secondary fracture reduction. METHODS: A search was performed in seven electronic databases. Observational studies reporting predictors after usual care of elderly patients with hip fracture diagnoses receiving surgical or conservative treatment were included. Primary outcomes considered were part of the domains corresponding to functional capacity. RESULTS: Of 3873 references identified, and after the screening and selection process, 43 studies were included. Sixty-one functional measures were identified for ten functional outcomes, including BADLs, IADLs, ambulation, and mobility. Biological characteristics such as age, sex, comorbidities, cognitive status, nutritional state, and biochemical parameters are significantly associated. Determinants such as contact and size of social network and those related to institutional care quality are relevant for functional recovery at six and 12 months. Age, pre-fracture function, cognitive status, and complications continue to be associated five years after discharge. We found 74 associated factors to functional recovery of elderly hip fracture patients. Ten of the studies reported rehabilitation programs as suggested in KPI 9; none used the complete hip fracture core-set. CONCLUSION: Most of the associated factors for functional recovery of elderly hip fracture were biological, sociodemographic, or inherent factors to patients' baseline characteristics, including their pre-facture functional capacity. For the core-set and KPI's, we found an insufficient use and report. This study reports 61 different instruments to measure functional capacity. REGISTRATION NUMBER: PROSPERO (CRD42020149563).

Development and Validation of a New Scoring Tool to Evaluate the Clinical Evolution of Adult Patients with Nonsegmental Vitiligo.

BACKGROUND: Vitiligo has an unpredictable course and a variable response to treatment. Furthermore, the improvement of some vitiligo lesions cannot be considered a guarantee of a similar response to the other lesions. Instruments for patient-reported outcome measures (PROM) can be an alternative to measure complex constructions such as clinical evolution. OBJECTIVE: The aim of this study was to validate a PROM that allows to measure the clinical evolution of patients with nonsegmental vitiligo in a simple but standardized way that serves to gather information for a better understanding of the disease. METHODS: The instrument was created through expert consensus and patient participation. For the validation study, a prospective cohort design was performed. The body surface area affected was measured with the Vitiligo Extension Score (VES), the extension, the stage, and the spread by the evaluation of the Vitiligo European Task Force assessment (VETFa). Reliability was determined with test-retest, construct validity through hypothesis testing, discriminative capacity with extreme groups, and response capacity by comparing initial and final measurements. RESULTS: Eighteen semi-structured interviews and 7 cognitive interviews were conducted, and 4 dermatologists were consulted. The instrument Clinical Evolution-Vitiligo (CV-6) was answered by 119 patients with a minimum of primary schooling. A wide range was observed in the affected body surface; incident and prevalent cases were included. The average time to answer the CV-6 was 3.08 ± 0.58 min. In the test-retest (n = 53), an intraclass correlation coefficient was obtained: 0.896 (95% CI 0.82-0.94; p < 0.001). In extreme groups, the mean score was 2 (2-3) and 5 (4-6); p < 0.001. The initial CV-6 score was different from the final one and the change was verified with VES and VETFa (p < 0.05, n = 92). CONCLUSIONS: The CV-6 instrument allows patient collaboration, it is simple and brief, and it makes it easier for the doctor to focus attention on injuries that present changes at the time of medical consultation.

Systematic Review of Clinimetric Instruments to determine the severity of Non-segmental Vitiligo.

This systematic review of measurement instruments for vitiligo outcomes included validation articles published from 2011 to May 2018. According to the PRISMA statement, the search was carried out in EMBASE (via OvidSP); MEDLINE (via OvidSP and PubMed). The COSMIN taxonomy will be used to define the measurement properties. Inclusion criteria were original studies reporting measuring properties. Exclusion criteria were clinical trials using scales whose measurement properties were not assessed, studies of cross-cultural adaptation, scales focused on other aspects of the disease such as quality of life, satisfaction, disease's burden. Fourteen studies were identified, which described 15 instruments to measure vitiligo outcomes. Nine of them, measured properties related to the severity of the disease: Vitiligo extent score (VES), Self-Assessment Vitiligo Extent Score (SA-VES), Self-Assessed Vitiligo Area Scoring Index (SAVASI), Vitiligo Area Scoring Index (VASI), Vitiligo European Task Force assessment (VETFa), Vitíligo Noticeability Scale (VNS), Koebner's phenomenon in vitiligo score (K-VSCOR), Vitiligo Extent Tensity Index (VETI), Potential Repigmentation Index (PRI). The most effective tool to asses affected Body Surface Area (BSA) is VES. The VASI is useful to stratify by severity. There is not enough evidence to recommend the use of SAVASI. The VETFa does not offer any difference to calculate the affected BSA compared with the rule of 9's. The VNS and K-VSCOR lack of reliability evidence.

[Diagnóstico tardío de psoriasis: motivos y consecuencias]. / Late diagnosis of psoriasis: Reasons and consequences.

BACKGROUND: Psoriasis is an autoimmune skin disease that may be associated with articular manifestations, and the most common clinical presentation is the variety "in plaques". In Mexico, in the Centro Dermatológico Pascua, it is the eighth leading cause of consultation. The aim of this study was to determine the diagnostic process of patients in a reference center for diseases of the skin. METHODS: Performing an analytical cross-sectional study that included 100 patients where the diagnostic process was questioned, clinimetric scales were applied and evaluated anthropometric. RESULTS: It was found that 70% of patients had taken over a month to get medical care (median: 3 months; IQR: 11 months), having consulted in 61% to a general physician as a doctor of first contact and 89% being diagnosed by a dermatologist. Eighty-eight percent of the patients were overweight or obese. We found as a factor of delay, a partnership with the variable of having an Institutional Medical Service (p = 0.019; U = 695.5). CONCLUSION: it is necessary to design a system to shorten the diagnostic process, not only in psoriasis, in addition to emphasizing dermatological education.

[Insulin levels in teenagers with comedonal acne]. / Niveles de insulina en adolescentes con acné comedónico.

INTRODUCTION: Acne is considered a multifactorial skin disease secondary to an obstructive process of pilosebaceous units. Some studies suggest a relationship between insulin levels and the presence of acne, but this has not yet been demonstrated. OBJECTIVE: To compare the levels of insulin in patients with and without comedonal acne. MATERIAL AND METHODS: From January to July 2012, we conducted a cross-sectional study in the Dr. Ladislao de la Pascua Dermatologic Center in Mexico city. We recruited men and women from 14 to 25 years old with and without comedonal acne. We measured the insulin levels in all patients with DXI 800 Beckman Coulter equipment in a blood sample. RESULTS: Twenty patients with acne and 20 patients without acne were studied, with an average age of 17 (±3) and 19 (±4) years, respectively. Both groups were different in terms of gender. Body mass index was similar in both groups. We did not find a difference in insulin levels between groups (p=0.818). The average level of insulin was 7.15±4.7 uU/ml for the acne group and 7.85±3.3 uU/mL for the control group. CONCLUSION: Insulin levels are similar in patients with and without comedonal acne. There is no direct relationship between hyperinsulinemia and acne.

[Validation of a questionnaire to quantify the risk for skin cancer]. / Validación de un cuestionario para cuantificar el riesgo de cáncer de piel.

INTRODUCTION: Currently, strategies are needed to identify the population at risk for skin cancer in order to implement prevention and for early diagnosis. There are no validated Spanish language instruments to measure skin cancer risk. OBJECTIVES: To design and validate a self-applied questionnaire to quantify the risk of melanoma and non-melanoma skin cancer in a Mexican population. METHODS: A self-applied questionnaire was designed to measure risk factors for skin cancer. Face and content validity was assessed by five experts in skin cancer. The value of each item was weighted according to the relative risk of the risk factors. The questionnaire was applied to extreme groups in order to measure the construct validity. Reliability was evaluated using test-retest method two weeks after the first application. RESULTS: The questionnaire was applied to patients with (n = 147) and without (n = 249) skin cancer from the Dermatologic Center "Dr. Ladislao de la Pascua". The total score of the questionnaire was different in both groups (U = 2,104.5, p = 0.0001) and ROC curve determined that five points or more equals high risk for skin cancer (area 0.964; 95% CI: 0.946-0.981; p = 0.0001). The reliability of the instrument was 0.971 (95% CI: 0.943-0.986; p = 0.0001). CONCLUSION: This is the first Spanish language questionnaire valid to measure risk of skin cancer, whose application at the population level would be useful to identify high-risk individuals who need preventative interventions.

Patient safety climate research in primary care dentistry: A systematic scoping review.

BACKGROUND: Patient safety climate constitutes an important element for quality improvement. Its current evidence base has been generated in hospital settings in developed countries. Studies in dentistry are limited. OBJECTIVE: To systematically explore the evidence regarding assessing patient safety climate in dentistry. METHODS: We developed a search strategy to explore MEDLINE, SCOPUS, and Web of Science databases from January 1st, 2002, to December 31st, 2022, to include observational studies on patient safety culture or patient safety climate assessment. Methodological features and item data concerning the dimensions employed for assessment were extracted and thematically analyzed. Reported scores were also collected. RESULTS: Nine articles out of 5584 were included in this study. Most studies were generated from high-income economies. Our analysis revealed methodological variations. Non-randomized samples were employed (ranging from 139 to 656 participants), and response rates varied from 28% to 93.7%. Three types of measurement instruments have been adapted to assess patient safety climate. These mainly consisted of replacing words or rewording sentences. Only one study employed an instrument previously validated through psychometric methods. In general, patient safety climate levels were either low or neutral. Only one study reported scores equal to or greater than 75. DISCUSSION: Despite diverse assessment tools, our two-decade analysis reveals a lag compared with medicine, resulting in methodological variations for assessing patient safety climate. Collaboration is vital to elevate standards, prioritize patient safety across oral healthcare services, and advocate for integrating safety climate into local and national quality and patient safety strategies.

Interventions for preventing keratinocytic cancer in patients with a history of a previous keratinocytic carcinoma: A systematic review.

Keratinocyte cancer (KC) is the most common cancer worldwide. It is important to analyze the actual interventions that are available for the prevention of patients with a previous history of a KC. We aim to review the existent literature to assess the efficacy and safety of interventions to prevent KC in patients with a history of previous KC. We searched clinical trials in which the main outcome was the prevention of KC in patients with a previous history of KC using the strategy published in the International Prospective Register of Systematic Reviews (PROSPERO registry), CRD42016045981. We analyzed 18 clinical trials from which eight reported a benefit with their respective intervention but had methodological flaws and a variable risk of bias. Two clinical trials (regarding celecoxib and oral supplementation with nicotinamide) seemed to have the most beneficial results reducing the incidence of KC in treated groups. However, all of the studies are highly heterogeneous, which does not allow a meta-analysis to be performed. New studies with greater epidemiological value should be conducted.

Low-dose oral isotretinoin in the treatment of recalcitrant facial flat warts: A clinical case and review of literature.

Background and Aims: The treatment of recalcitrant facial flat warts has always been challenging for dermatologists. The pain related to the application of the different treatments, side effects and costs are determining factors in the choice of therapy. To date, it is known that oral isotretinoin administered at a dose of 0.5 mg/kg/day is effective and safe; However, the different adverse effects reported have a dose-dependent behavior and they could limit their use. Our aim is to assess the effect of low-doses of oral isotretinoin to reducing side effects in the complete removal of recalcitrant facial flat warts and the current evidence in this regard. Methods: An extensive literature review was conducted to identify articles relating to low doses of oral isotretinoin for recalcitrant flat warts treatment, regardless of design up to May 2023. Results: The literature search yielded eight articles of 324 reviewed meeting criteria. Isotretinoin was administered in doses of 0.1-0.5 mg/kg/day. Complete elimination of the lesions occurred in 65.13% of the patients and a partial response in 19.26%. Four relapses were documented at the 4-month follow-up. The most frequent adverse effect was cheilitis. Conclusion: We might consider low doses of oral isotretinoin for the treatment of recalcitrant facial flat warts in which side effects need to be reduced. However, current published works have several limitations, including small sample sizes, lack of control group and follow-up periods. Larger, randomized, controlled studies are needed to verify the efficacy and safety of different doses of isotretinoin.

[Clinical guideline. Preeclampsia-eclampsia]. / Guía de práctica clínica. Preeclampsia-eclampsia.

Preeclampsia remains a major cause of worldwide pregnancy related maternal and neonatal mortality and morbidity, it accounts for more than 50,000 maternal deaths each year. The World Health Organization estimates that at least one woman dies every 7 minutes from a complication of preeclampsia. It is the main cause of maternal death in Mexico and Latin America. Standarized assessment and surveillance of women with preeclampsia is associated with reduced maternal risk. Standarized sequence was established to search for practice guidelines from the clinical questions raised on diagnosis and treatment of preeclampsia-eclampsia. The working group selected clinical practice guidelines found in the Cochrane Library, Medline and PubMed. The results were expressed as levels of evidences and grade of recommendation. Evidence suggests, that treatment of severe hypertension, seizures prophylaxis with magnesium sulfate, and management by experienced health-care professionals will improve maternal, fetal and neonatal outcomes. Treatment remains supportive with pregnancy termination being the only definitive cure.

[Clinical guide practice. Patent ductus arteriosus]. / Guía de práctica clínica. Persistencia del conducto arterioso.

Patent ductus arteriosus (PDA) is the most common congenital heart disease in Mexico. The clinical manifestations of the PCA are from asymptomatic patients to the presence of heart failure. Its management should be individualized based on clinical, hemodynamic data and presence of pulmonary hypertension. Our objective was to provide current medical recommendations based on the best, available scientific evidence for the diagnosis, study and therapeutic decisions of the PCA. Established a standardized sequence to search for Practice Guidelines, based on the clinical questions about PCA diagnosis and treatment. Most of the recommendations were taken from selected guidelines and supplemented with the remaining material. The information is expressed in levels of evidence (E) and grade of recommendation (R) according to the characteristics of the study design and type of publications. Currently produces large amounts of medical information in a relatively short period of time which is necessary to have evidence-based CPG to facilitate and standardize the diagnostic decision-treatment to provide better care for children and adults with PCA.

Keratosis Pilaris Treatment: Evidence from Intervention Studies.

Keratosis pilaris is a common dermatosis observed in daily dermatologic practice. The diagnosis is clinical and usually asymptomatic, although sometimes patients may complain of mild pruritus and its cosmetic appearance. Few reports exist about its treatment. There are clinical trials assessing topical treatments and laser surgery, but no systematic reviews on its management were found in literature. An online research was conducted to identify evidence-based recommendations. Lactic acid, salicylic acid, and the 1064-nm Nd:YAG laser seem to be the most effective and safe treatment options for keratosis pilaris among patients aged 12 years and older; however, high-quality randomized controlled trials with long-term outcomes are required. (SKINmed. 2022;20:258-271).

[Clinical guideline for detection and diagnosis of hypertensive pregnancy disease]. / Guía de práctica clínica. Enfermedades hipertensivas del embarazo.

Hypertensive disorders in pregnancy (HDP) are the main complication and cause of maternal and perinatal death. Pre-eclampsia represents a 34%, according to the Secretaría de Salud de México. To offer the family physicians tools for the opportune detection and diagnosis of HDP a clinical guideline was developmented. Clinical questions were formulated and structured. A standardized sequence to search for Practice Guidelines, based on the key words: hypertensive disorders in pregnancy, pre-eclampsia. Tripdatabase, MDConsult, National Guideline Clearinghouse, Scottish Intercollegiate Guidelines Network, National Institute for Health and Clinical Excellence were used. In addition, Cochrane Library Plus, Science Direct and OVID were used. Most of the recommendations were taken from guidelines selected and supplemented with the remaining material. The information is expressed in levels of evidence and grade of recommendation according to the characteristics of the study design and type of publications. To reduce morbidity and mortality from HDP health professionals should identify risk factors; conduct a close monitoring and early diagnosis. It is essential to provide information to the pregnant patient on alarm data and behavior to follow. This clinical practice guide offers current evidence for screening and diagnosis of HDP in primary care.

[Usefulness of a clinical questionnaire for screening osteopenia and osteoporosis in post-menopausal women]. / Utilidad de un cuestionario clínico en la detección de osteopenia y osteoporosis en la posmenopausia.

BACKGROUND: The prevalence of osteoporosis in post-menopausal women (PMW) is 30 %, and bone densitometry (BD) is the gold standard. This is not recommended as a screening test because of its cost. Instead, the SCORE index (Simple Calculated Osteoporosis Risk Estimation) is proposed. The objective is to determine the sensitivity and specificity of this test in the population and the optimization of BD. METHODS: The SCORE Index is a pre-screening questionnaire; it was used in PMW to compare with BD, registering the total score of the questionnaire, densitometry diagnosis, the fracture risk and the site of osteoporosis. The sensitivity and specificity of SCORE Index and chi(2) of Mantel-Hanszel were calculated. RESULTS: We studied 201 patients, mean age 55.70 years. Osteoporosis was recognized in 22.8 %, osteopenia in 68.3 % and 8.9 % was normal. The sensitivity of the SCORE index was 87 % (95 % CI = 77-97) and specificity was 34.6 % (95 % CI = 27-42) with p = 0.000. A positive probability quotient of 1.33 (95 % CI = 1.1-1.7). CONCLUSIONS: Osteoporosis is a frequent disease in PMW. It is mandatory to have cheap and easy-tools which can detect osteoporosis cases.

[The clinical guidelines of practice project at the Instituto Mexicano del Seguro Social]. / Proyecto para el desarrollo de guías de práctica clínica en el Instituto Mexicano del Seguro Social.

The advance in the knowledge and technology is growing quickly and greater quantity, so it is difficult for the health professional to access to whole information that is generated every day on diagnostic and therapeutic strategies more effective, so the clinic practice guidelines (CPG) is a resource to support the updating of the health professional and support them in making clinical decisions. The CPG is also a better support to the manager of health services in making decisions regarding the strategies that have performed for the patient and less risk to the individual and collective health. They also support the response capacity of the medical units and hospitals and guide the planning of services to the optimization of the resources. This paper summarizes the methodology of a national project for the development of GPC coordinated by the Mexican Social Security Institute with the collaboration of more than 1200 health professionals of the institution in a great effort institutional update and make information accessible to the entire health sector, which also defines the steps to upgrade and maintain the updating of knowledge and technology expressed in them.

[A clinical guideline for diagnosis and treating of diabetes during pregnancy]. / Guía de práctica clínica. Diagnóstico y tratamiento de la diabetes en el embarazo.

BACKGROUND: Metabolic disturbance commonly occurs during pregnancy and perinatal outcome harms, with increased maternal-fetal morbidity. The prevalence of diabetes during pregnancy in Mexico is 7%. OBJECTIVE: To develop a guideline available to the staff of the first, second and third level of care, that includes recommendations based on the best available evidence. METHODS: Clinical questions were formulated and structured. Standardized sequence was established to search for practice guidelines from the clinical questions raised on diagnosis and treatment of diabetes and pregnancy. The working group selected clinical practice guidelines. We found eleven guidelines which took many of the recommendations. For recommendations not included in the reference guides the search process was conducted in PubMed and Cochrane Library. The results were expressed as levels of evidence and grade of recommendation. CONCLUSIONS: Diabetes mellitus during pregnancy increases perinatal morbidity and mortality. The recommendations in this evidence-based guide will help to make diagnosis and treatment standardized to reduce the consequences of disease.

Quality of clinical trials for the prevention of keratinocyte cancer.

Keratinocyte cancer (KC) is the most common form of cancer in humans. To our knowledge, no previous publications assessing the methodological quality of clinical trials for the prevention of KC have been recently published. We aim to assess the methodological quality of clinical trials focused on the prevention of KC in high-risk groups not receiving immunosuppressive therapy (NRIT) and propose solutions to improve the design of future trials. We searched clinical trials in which the main outcome was the prevention of KC in high-risk NRIT groups using the strategy published in the International Prospective Register of Systematic Reviews (PROSPERO registry), CRD42016045981. Consolidated Standards of Reporting Trials (CONSORT) criteria and the Cochrane Collaboration risk of bias tool were used to assess methodological quality. We analyzed 23 clinical trials. We found a high risk of attrition and reporting bias in 86.9% and 60.9% of the trials, respectively. Regarding the CONSORT criteria, in at least 40% of the trials, the authors omitted the following information: a description of the trial design, the number of losses and exclusions after randomization, the results of subgroup and adjusted analysis, the estimated effect size and the precision of primary and secondary outcomes. Methodological quality was improved in the recently published clinical trials compared to those published before the CONSORT criteria development. All clinical trials should report in detail the information used to assess potential risks of bias.

Diagnostic Accuracy of Dermoscopy of Actinic Keratosis: A Systematic Review.

INTRODUCTION: Dermoscopy is a tool that aids clinicians in the diagnosis of actinic keratosis; however, few diagnostic accuracy studies have determined its sensitivity and specificity for this diagnosis. OBJECTIVE: Determine the diagnostic accuracy of dermoscopy on actinic keratosis. METHODS: A systematic review was conducted on EMBASE, PubMed, Scopus and the Cochrane Central Registry of Controlled Trials from inception to August 2019. RESULTS: We screened 485 titles and abstracts. Two studies comprising 219 actinic keratoses were eligible for qualitative analysis. The number and heterogeneity of included studies limited a quantitative analysis. CONCLUSIONS: Studies that focus specifically on the diagnostic accuracy of dermoscopy for actinic keratosis are lacking.

Prognostic Factors in Mexican Patients with Patchy and Other Types of Alopecia Areata.

INTRODUCTION: Some clinical features have been associated with the progression and remission of alopecia areata (AA). We aim to determine possible prognostic factors in Mexican patients with AA. METHODS: This prospective study of a 1-year follow-up included Mexican patients with a clinical diagnosis of AA. We evaluated disease activity with the SALT score at the first visit and 1-year follow-up; progression, no progression, and remission were defined according to score changes. We used multiple linear regression model to detect factors associated with progression and remission. RESULTS: One hundred and four patients concluded the study. Ninety-seven patients (93.3%) had patchy AA. Fifteen patients showed disease progression and 89 no progression, of which 35 patients had remission. Body hair involvement was related to disease progression and adherence to treatment with disease remission and progression. CONCLUSIONS: Body hair involvement is related to poor prognosis. Adherence to treatment is a modifiable prognostic factor associated with the course of AA in Mexican patients.

Spanish Version of the System Usability Scale for the Assessment of Electronic Tools: Development and Validation.

BACKGROUND: The System Usability Scale (SUS) is a common metric used to assess the usability of a system, and it was initially developed in English. The implementation of electronic systems for clinical counseling (eHealth and mobile health) is increasing worldwide. Therefore, tools are needed to evaluate these applications in the languages and regional contexts in which the electronic tools are developed. OBJECTIVE: This study aims to translate, culturally adapt, and validate the original English version of the SUS into a Spanish version. METHODS: The translation process included forward and backward translation. Forward translations were made by 2 native Spanish speakers who spoke English as their second language, and a backward translation was made by a native English speaker. The Spanish SUS questionnaire was validated by 10 experts in mobile app development. The face validity of the questionnaire was tested with 10 mobile phone users, and the reliability testing was conducted among 88 electronic application users. RESULTS: The content validity index of the new Spanish SUS was good, as indicated by a rating of 0.92 for the relevance of the items. The questionnaire was easy to understand, based on a face validity index of 0.94. The Cronbach α was .812 (95% CI 0.748-0.866; P<.001). CONCLUSIONS: The new Spanish SUS questionnaire is a valid and reliable tool to assess the usability of electronic tools among Spanish-speaking users.
