Medidas de bioseguridad contra la COVID-19 durante la atención odontológica, en una región del Perú

Introducción: La atención odontológica, por su propia naturaleza, implica un mayor riesgo de trasmisión del SARS-CoV-2. Por tanto, es esencial que el personal del centro odontológico extreme las medidas de bioseguridad durante y después de la crisis sanitaria. Objetivo: evaluar el cumplimiento de las medidas de bioseguridad contra la COVID-19 durante la atención odontológica, en una región del Perú. Materiales y métodos: Estudio transversal realizado en la región de Ica, en Perú. Participaron 304 odontólogos de la práctica pública y privada. Se recogieron características sociolaborales y de salud. El cumplimiento de medidas de bioseguridad fue evaluado con la Escala de Bioseguridad para COVID-19, diseñada y validada por los investigadores. Se realizó un análisis descriptivo y se evaluaron diferencias con la prueba chi-cuadrado. Resultados: El 72,7 % de los participantes incumplen las medidas de bioseguridad. Se observaron mayores proporciones de incumplimiento entre los odontólogos de 41 a 50 años de edad (76 %), sin segunda especialidad (76,4 %), y en quienes recibieron la primera (100 %) y la segunda dosis (90,4 %) de la vacuna contra la COVID-19. Asimismo, entre los odontólogos que laboran en el sector privado que no tienen segunda especialidad (75,3 %); entre los que recibieron la primera dosis de la vacuna contra la COVID-19 (100 %) y la segunda dosis (92,2 %) respectivamente; en quienes tuvieron dos veces (100 %) y más de dos veces (100 %) COVID-19, y en aquellos que no tuvieron familiar fallecido por el coronavirus. Todas estas diferencias alcanzaron significancia estadística (p < 0,05). Conclusión: Durante la atención odontológica se incumplen las medidas de bioseguridad. Existen ciertos factores como la edad entre 41 y 50 años, no tener segunda especialidad, entre otros, que podrían incrementar la probabilidad de incumplir estas medidas.

Introduction: Dental care, by its proper nature, implies a higher risk of SARS-CoV-2 transmission. It is therefore essential that the dental center staff carry to extremes biosecurity measures during and after the health crisis. Objective: To evaluate compliance with biosecurity measures against COVID-19 during dental care in a region of Peru. Materials and methods: Cross-sectional study carried out in the region of Ica, in Peru. 304 dentists from public and private practice participated. Socio-occupational and health characteristics were collected. Compliance with biosecurity measures was evaluated with the Biosecurity Scale for COVID-19, designed and validated by the researchers. A descriptive analysis was performed and differences were evaluated with the chi-square test. Results: 72.7% of the participants fail to comply with the biosecurity measures. Higher proportions of non-compliance were found among the dentists from 41 to 50 years old (76%), without a second specialization (76.4%), and in those who received the first (100%) and the second (90.4%) doses of the vaccine against COVID-19. Likewise, among dentists who work in the private sector and do not have second specialty (75.3%); among those who received the first dose (100%) and the second dose (92.2%) of the vaccine against COVID-19 respectively; in those who had COVID-19 twice (100%) and more than twice (100%), and in those dentist who did not have relatives deceased by coronavirus. All these differences reached statistical significance (p < 0, 05). Conclusions: Biosafety measures are breached during dental care. There are several factors like age between 41 and 50 years, not having a second specialty among others that could increase the probability of failing to comply with these measures.

General anesthesia versus conscious sedation during endovascular treatment in posterior circulation large vessel occlusion: A systematic review and meta-analysis.

Purpose: The optimal anesthetic approach in the endovascular treatment (EVT) of patients with posterior circulation large vessel occlusion (PC-LVO) strokes is not clear. Little data has been published and no randomized clinical trials have been conducted so far. We aimed to perform an updated meta-analysis to compare clinical and procedural outcomes between conscious sedation (CS) and general anesthesia (GA). Methods: We reviewed the literature of the studies reporting CS and GA in patients with endovascularly-treated PC-LVO. The primary outcome was the functional outcome at 3 months measured using the modified Rankin Scale (mRS). A good functional outcome was defined as having a mRS 0-2. Secondary outcomes were mortality at 3 months, final successful recanalization (modified Thrombolysis in Cerebral Infarction (mTICI) scale from 2b to 3) and complete recanalization (mTICI of 3) and times from stroke onset to EVT completion. Random-effects models were completed to pool the outcomes and the I 2 value was calculated to assess heterogeneity. Findings: Eight studies with a total of 1351 patients were included. The pooled results reveal that CS use was associated with higher rates of good outcome (OR 2.41, 95% CI 1.58-3.64, I 2 = 49.67%) and with lower mortality at 3 months (OR 0.48, 95% CI 0.28-0.82, I 2 =57.11%). No significant differences were observed in the final reperfusion rates, procedural duration, and time from stroke onset to EVT completion. Conclusion: In this meta-analysis, GA was associated with significantly lower rates of functional independence at 3 months in patients with PC-LVO strokes.

[Characteristics of Helicobacter pylori infection in a private hospital in Lima, 2019 experience and literature review]. / Características de la infección de Helicobacter pylori en un hospital privado de Lima, experiencia del 2019 y revisión de la literatura.

Digestive diseases are the fourth leading cause of outpatient care in Peruvian healthcare centers, with gastritis and peptic ulcers being the most common. This is a retrospective, cross-sectional, descriptive study of secondary analysis of medical record data to evaluate the prevalence of Helicobacter pylori in patients undergoing upper digestive endoscopy during 2019 at Clinica Delgado, Lima, Peru. An association between males (PRa 1.27, 95% CI 1.10-1.48, p<0.001), age categories and upper digestive endoscopy (PRa 2.53, 95% CI 2.16-2.97, p<0.001) was reported. Based on these findings, it is recommended that other causes of gastritis be identified, especially in young women with deep chronic gastritis. Furthermore, we present a review of the scientific literature of Peru on factors associated with the positivity of Helicobacter pylori in the results of superior digestive endoscopy.

Progressive Lacunar Strokes: A Predictive Score.

BACKGROUND AND PURPOSE: Progressive lacunar syndromes (PLS) occur in up to 20-30% of patients with lacunar strokes, increasing the risk of long term dependency. Our aim is to develop a predictive score to identify patients at high risk of presenting PLS. METHODS: We derived a risk score for PLS in a cohort of consecutive patients (n=187) presenting with one of the five classic lacunar syndromes (LS) and absence of vascular occlusion, perfusion deficit or symptomatic stenosis. A risk score was developed using the coefficients from the logistic regression model, and receiver operating characteristic (ROC) analysis was conducted to assess the prognostic value of the risk score. Sensitivity, specificity and accuracy were estimated for each total point score. RESULTS: Out of 187 patients included in our sample, 52 (27.8%) presented PLS. Previous history of diabetes mellitus (1 point), diastolic blood pressure at admission (2 points), clinical deficits consistent with a pure motor syndrome (1 point) and asymptomatic intracranial atheromatosis or stenosis in non-symptomatic territory (1 point) were independent predictors for PLS. The estimated area under the ROC curve for this model was 0.77 (95% CI,0.68 - 0.84). CONCLUSION: This score could be a useful tool in routine clinical practice to predict the occurrence of PLS, allowing the identification of those patients with LS who are at high risk of long term dependency due to early neurological worsening, and who would benefit the most from an intensive treatment.

¿Movimientos involuntarios asociado a corrección por déficit de vitamina B12?: A propósito de un caso / Involuntary movements associated with correction of vitamin B12 deficiency?: A case repor

Antecedentes: La deficiencia de vitamina B12 es un problema nutricional que puede cursar con manifestaciones neurológicas y hematológicas. Existen limitados reportes sobre la aparición de movimientos involuntarios al iniciar tratamiento con cianocobalamina. Descripción del caso: Lactante de 5 meses presentó vómitos, palidez y dificultad para sostener la cabeza. Dentro de los exámenes se encontró pancitopenia y déficit de vitamina B12 en el paciente y la madre. Se administró tratamiento con ácido fólico y cianocobalamina; sin embargo, al cuarto día de tratamiento presentó movimientos coreiformes por lo que se administró clonazepam. La tomografía y el electroencefalograma fueron normales. Al seguimiento el recuento de plaquetas y leucocitos mejoraron y los movimientos remitieron gradualmente. Conclusiones: La aparición de movimientos involuntarios cuando se realiza la corrección por déficit de vitamina B12 es poco reportado. La evaluación al seguimiento es importante para evitar la sobremedicación innecesaria.

Background:Vitamin B12 deficiency is a nutritional problem that can present with neurological and hematological manifestations. There are limited reports on the appearance of involuntary movements when initiating cyanocobalamin treatment. A 5-month-old infant presented vomiting, paleness, Case report:and difficulty holding his head. Among the examinations, pancytopenia and vitamin B12 deficiency were found in the patient and the mother. Treatment with folic acid and cyanocobalamin was administered; However, on the fourth day of treatment, she presented choreiform movements for which clonazepam wasadministered.Thetomographyandtheelectroencephalogramwere normal. At follow-up, the platelet and leukocyte count improved and the movements gradually remitted. Little is reported about the Conclusion:occurrence of involuntary movements when vitamin B12 deficiency is corrected. Follow-up evaluation is important to avoid unnecessary overmedication.

Effect of combined acetylsalicylic acid and statins treatment on intracranial aneurysm rupture.

BACKGROUND: Acetylsalicylic acid (ASA) and statins have been identified as potentially reducing the risk of intracranial aneurysms (IA) rupture. We aim to determine the effect of this drugs on the risk of rupture of IA. PATIENTS AND METHODS: We performed a retrospective cohort study from a prospective database of patients with IA treated in our institution between January 2013 and December 2018. Demographics, previous oral treatments, presence of multiple aneurysms, size of aneurysm, lobulation, location and morphology of the aneurysms were recorded. Patients were dichotomized as ruptured and unruptured IA. RESULTS: A total of 408 IA were treated, of which 283 (68.6%) were in women. The median age was 53, 194 (47.5%) were ruptured IA. 38 patients (9.3%) were receiving ASA and 84 (20.6%) were receiving statins at the moment of the IA diagnosis. In the multivariable regression analysis, ASA plus statin use and multiple aneurysms were independently associated with unruptured IA (OR 5.01, 95% CI, 1.37-18.33, P = 0.015 and OR 2.72, 95% CI 1.68-4.27, P<0.001, respectively). Whereas, lobulated wall aneurysm and PComA/AComA location were inversely and independently associated with unruptured IA condition (OR 0.34, 95% CI 0.21-0.55, P<0.001 and OR 0.37, 95% CI 0.23-0.60, P<0.001, respectively). However, ASA and statins in monotherapy were not independently associated with unruptured IA condition. CONCLUSIONS: In our study population ASA plus statins treatment is independently associated with unruptured IA. Larger and prospective studies are required to explore this potential protective effect against IA rupture.

Impact of general anesthesia on posterior circulation large vessel occlusions after endovascular thrombectomy.

BACKGROUND: The impact of general anesthesia on functional outcome in patients with large vessel occlusion remains unclear. Most studies have focused on anterior circulation large vessel occlusion; however, little is known about the effect of general anesthesia in patients with posterior circulation-large vessel occlusion. METHODS: We performed a retrospective analysis from the prospective CICAT registry. All patients with posterior circulation-large vessel occlusion-and undergoing endovascular therapy between January 2016 and January 2020 were included. Demographics, baseline characteristics, procedural data, and anesthesia modality (general anesthesia or conscious sedation) were evaluated. The primary outcome was the proportion of patients with good clinical outcome (modified Rankin Scale score of 0-2) at three months. RESULTS: 298 patients underwent endovascular treatment with posterior circulation-large vessel occlusion-were included. Age, diabetes mellitus, renal insufficiency, baseline National Institutes of Health Stroke Scale score, puncture to recanalization length, ≥3 device passes, absent of successful recanalization (defined as treatment in cerebral ischemia of 3), and general anesthesia were statistically associated with poor outcome (mRS: 3-6). In the multivariable regression, general anesthesia and ≥3 device passes were independently associated with poor outcome (aOR: 3.11, (95% CI: 1.34-7.2); P = 0.01 and 3.77, (95% CI: 1.29-11.01); P = 0.02, respectively). Patients treated with general anesthesia were less likely to have a good outcome at three months compared to conscious sedation (19.7% vs. 45.1%, P < 0.001). CONCLUSIONS: In our study population, general anesthesia use is associated with poor clinical outcome in patients with posterior circulation-large vessel occlusion-treated endovascularly.

Troponin T Predicts Cardioembolic Aetiology and Clinical Outcome in Undetermined Ischaemic Stroke in Hyperacute Phase.

BACKGROUND: Elevated high-sensitivity cardiac troponin T (hs-cTnT) levels have been related to clinical outcome in stroke patients. However, the role of hs-cTnT and its potential as a biomarker in ischaemic stroke (IS) has not been well established. This study aims to determine whether basal hs-cTnT determination in the hyperacute phase of undetermined IS and transient ischaemic attack (TIA) can predict the cardioembolic aetiology and clinical outcome. METHODS: We prospectively studied 110 consecutive patients with undetermined acute IS and TIA. hs-cTnT levels were determined at hospital arrival. Large vessel stenosis/occlusion and previously known aetiologies at admission were exclusion criteria for this study. All patients were subjected to a complete aetiological evaluation. A 12-month follow-up was performed in all patients. The subtype of IS was evaluated following the SSS-TOAST criteria. We established two groups at admission: cardioembolic aetiology (group A) and noncardioembolic aetiologies (group B). RESULTS: The number of patients in each group was similar (group A: 52, 47.27%; group B, 58, 52.73%). Patients in group A had elevated hs-cTnT more frequently (61.54% versus 17.24%; P < .001). Group A patients had significantly higher mortality at 3 months (14.29% versus 1.82%, P = .025). In the multivariate analysis, elevated hs-cTnT was the only independent predictor of cardioembolic aetiology (odds ratio: 14.821; 95% confidence interval: 3.717-59.102, P < .001). CONCLUSION: Baseline hs-cTnT assessment in undetermined strokes and TIA during the hyperacute phase is independently associated with cardioembolic aetiology.

Serotonin Reuptake Inhibitor Drugs Are Associated with Contrast Extravasation and Clinical Outcome in Patients with Intracerebral Haemorrhage.

BACKGROUND: Antidepressants that inhibit the reuptake of serotonin (SRIs) have been related to the appearance of intracerebral haemorrhage (ICH). Some studies have described bigger haematoma volumes in these patients. So far, no studies have demonstrated an association between SRIs and contrast extravasation (CE). We propose to investigate the relationship of SRIs with CE and clinical outcome. PATIENTS AND METHODS: We aimed a prospective registry of 294 patients with ICH. All previous treatments were registered, including SRIs intake. The presence of CE and the number of spot sign in CT angiography were collected. Early neurological deterioration (END) and late neurological deterioration (LND) were registered. Follow-up was completed at day 90. RESULTS: Two hundred and ninety-four patients were included, mean age 66.5 years, 27.6% female. A total of 28 (9.5%) were taking SRIs at the time of the ICH. This group of patients presented statistically significantly more CE (46.4 vs. 19.9%, p = 0.012), ≥2 spot sign (25 vs. 6.8%, p = 0.017), END (46.4 vs. 25.2%, p = 0.018) and LND (14.3 vs. 4.9%, p = 0.032). In addition, this group of patients showed a tendency to have higher mortality (32.1 vs. 22.2%, p = 0.553) and a lower functional independence (modified Rankin Scale 0-2) at day 90 (25 vs. 36.5%, p = 0.230). In the multivariate analysis, SRIs intake was identified as an independent predictor of CE (adjusted OR 3.37; 95% CI 1.033-10.989; p = 0.044) together with hematoma volume at baseline and alcohol use. CONCLUSIONS: In our studied population, previous SRIs intake in patients with ICH was independently associated to CE. Further studies are needed to confirm this association.

A Bibliometric Analysis of the Latin American Research on Stroke 2003-2017.

BACKGROUND: Stroke is a leading cause of mortality and disability worldwide. Research activity in Latin American countries might be the key to solving, or at least improving, the understanding of stroke-related issues in the region. Our aim was to describe and analyze the research output on stroke in Latin America. METHODS: We performed a bibliometric analysis of studies on stroke in Latin America reported from 2003 to 2017 in Scopus-indexed journals. We extracted the annual research, countries, journals, authors, institutions, citation frequency, and journal metrics. The data were quantitatively analyzed. Publication activity was adjusted to the countries by population size. Also, the results from an author and country co-occurrence analysis are presented as network visualization maps using VOSviewer. RESULTS: A total of 2298 Latin American stroke-related reports were identified, most were original research reports (72%). The number of reported studies had increased from 2003 to 2017 (P < 0.001). Brazil was the country with the greatest production with 1273 reports (55.4%), followed by Argentina and Mexico. No association was found between stroke prevalence and mortality and the scientific production of the country. Six universities and three hospitals were the most prolific institutions. A collaborative relationship was found between the United States and Brazil, Argentina, and Mexico. The intraregional collaboration of research on stroke was low among Latin American countries. CONCLUSIONS: Despite the continuous increase in research output from Latin American countries, more effort is needed to strengthen the research capacity by developing networks and collaborative research projects, ideally among the Latin American countries themselves.
