Comparison of short-term visual acuity and visual disturbance phenomena and spectacle independence after implantation of three different intraocular lenses / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To compare the short-term postoperative visual acuity, visual disturbance phenomena, and spectacle independence rate in patients who underwent monocular implantation with trifocal, multifocal, or extended range of vision intraocular lens(IOL).METHODS: A retrospective analysis was conducted on 67 cataract patients(67 eyes)who underwent phacoemulsification cataract extraction combined with IOL implantation from March 2019 to December 2022. A total of 35 cases(35 eyes)received Symfony extended range of vision IOL implantation, 21 cases(21 eyes)received AcrySof IQ ReSTOR +3D multifocal IOL, and 11 cases(11 eyes)received AcrySof IQ PanOptix trifocal IOL. The preoperative uncorrected distance visual acuity(UDVA), uncorrected intermediate visual acuity(UIVA), and uncorrected near visual acuity(UNVA)and 3 mo postoperatively were documented. Moreover, defocus curves, visual disturbance phenomena, and spectacle independence rates were recorded at 3 mo postoperatively.RESULTS: At 3 mo postoperatively, no statistically significant differences were observed in UDVA among the three groups(P>0.05). A comparison of UIVA showed superior results in the Symfony and PanOptix groups compared to the ReSTOR group(all P<0.01). The UNVA of both the ReSTOR and PanOptix groups outperformed the Symfony group(all P<0.01). The defocus curves indicated that in the intermediate vision range(-1.00 to -1.50 D), the Symfony group exhibited better performance than the ReSTOR group(P<0.05); while in the near vision range(-2.50 to -3.50 D), the ReSTOR group was superior to the Symfony group(P<0.05). The PanOptix group demonstrated superior visual acuity in the near vision range(-2.00 to -3.50 D)compared to the Symfony group(P<0.05)and was also superior in the intermediate vision range(-1.00 to -2.00 D)compared to the ReSTOR group(P<0.05). No significant differences were observed in the incidence of glare or halo and binocular interference phenomena among the three groups(P>0.05). The PanOptix and ReSTOR groups exhibited a higher spectacle independence rate compared to the Symfony group(P<0.0167).CONCLUSION: Compared to Symfony extended range of vision IOL and ReSTOR multifocal IOL, PanOptix trifocal IOL offers a balanced approach to distance, intermediate, and near visual acuity, without a high incidence of glare and halo, and with a higher spectacle independence rate. Caution is still advised when considering monocular implantation with presbyopia-correcting IOLs.

Diversidad y estructura del bosque de niebla en la Sierra Madre de Chiapas, México

Introducción: Los bosques de niebla se caracterizan por su distribución insular en sistemas montañosos tropicales. Florísticamente son complejos y heterogéneos, y con vacíos de información que afectan la comprensión de cómo varía su diversidad y estructura. Objetivo: Analizar los patrones de diversidad, estructura y composición del bosque de niebla en México. Métodos: Contamos y medimos plantas leñosas en 40 parcelas de 0.1 ha de cinco sitios en aproximadamente 200 km a lo largo de la Sierra Madre de Chiapas, México (1 700 - 2 100 m.s.n.m.). Usamos tres métodos estadísticos: análisis de varianza (diversidad verdadera y estructura entre sitios), regresión simple y métodos multivariados (clima y elevación). Resultados: Registramos 4 021 individuos (220 especies, 60 familias). En la diversidad verdadera, solo encontramos diferencias en riqueza de especies, con un ligero incremento hacia la parte central del área. La diversidad fue constante para especies comunes y dominantes. No encontramos diferencias en la densidad de árboles o área basal entre los sitios. Sin embargo, hubo menor densidad y mayor área basal a mayores elevaciones. La diversidad beta y la diferenciación en la composición florística es alta e importante entre las parcelas de un mismo sitio y se incrementa con la distancia entre los sitios. Conclusiones: La diversidad beta y la diferenciación florística contribuyen significativamente en la variación del bosque de niebla. Las variables climáticas y la altitud tienen efectos distintos sobre la diversidad y estructura.

Introduction: Cloud forests are noted for their narrow distribution in tropical mountain systems. Floristically, they are complex and heterogeneous, with gaps in information that hinder the understanding of how their diversity and structure vary. Objective: To analyze patterns of diversity, structure, and composition of the cloud forest in Mexico. Methods: We counted and measured woody plants in forty 0.1 ha plots from five sites in approximately 200 km along the Sierra Madre of Chiapas, Mexico (1 700 - 2 100 m.a.s.l.). We used three statistical methods: analysis of variance (diversity true and structure among sites), simple regression and multivariate statistics (climate and elevation). Results: We recorded 4 021 individuals (220 species, 60 families). In true diversity, we only found differences for species richness, with a slight increase toward the central part of the area. Diversity was constant for common and dominant species. We found no differences in tree density or basal area between sites. However, there was less density and more basal area at higher elevations. Beta diversity and differentiation in floristic composition are high and important between plots of the same site, and they increase with distance between sites. Conclusions: Beta diversity and floristic differentiation significantly contribute to variation in the cloud forest. Climatic variables and altitude have different effects on diversity and structure.

Avifauna en fragmentos de Bosque Mesófilo de Montaña y vegetación secundaria en el municipio de Huatusco, Veracruz / Birds in patches of cloud forest and secondary forest in the municipality of Huatusco, Veracruz

RESUMEN El Bosque Mesófilo de Montaña (BMM) del centro de Veracruz, México, representa un paisaje alterado por actividades antrópicas, por lo que es necesario evaluar el potencial evolutivo y adaptativo de las aves refugiadas en el sitio, las cuales se enfrentan a un paisaje con un gradiente heterogéneo. El objetivo de este estudio fue determinar la diversidad de aves en fragmentos de BMM y vegetación secundaria (VS), en el predio Finca La Pastoría, Huatusco, Veracruz, así como, asociar su presencia y/o alimentación a cada hábitat evaluado. Se identificaron las especies y número de individuos en 14 sitios de observación de aves, con el método de muestreo basado en conteo por puntos con radio fijo de 30 m. Se registraron 100 especies pertenecientes a 33 familias y 15 órdenes. En el BMM se identificaron 916 individuos, correspondientes a 89 especies, y en VS 331 individuos de 54 especies, encontrando diferencias significativas de diversidad de aves entre coberturas de muestreo. Destacan los registros de Dendrortyx barbatus, Leptotila verreauxi y Vireo griseus, por ser endémicas. La primera está clasificada en peligro de extinción, mientras que la segunda se encuentra sujeta a protección especial y la tercera amenazada. También se registraron Pionus senilis, especie amenazada; Falco peregrinus, Micrastur semitorquatus, Passerina ciris, Psarocolius montezuma, Myadestes occidentalis y Amazona albifrons, sujetas a protección especial. Este estudio brinda información sobre cómo la avifauna hace uso diferencial de dos coberturas de vegetación, la cual puede servir para generar estrategias sustentables para el manejo y conservación del bosque.

ABSTRACT The Cloud Forest (CF) in central Veracruz, Mexico, represents a landscape that has been altered by anthropic activities. Therefore, it is necessary to evaluate the evolutionary and adaptive potential of the birds sheltered in the site, which face a landscape with a heterogeneous gradient. The objective of the study was to describe the diversity of birds in fragments of CF and secondary vegetation (VS), in the property "Finca La Pastoría", Huatusco, Veracruz. The species and number of individuals in 14 bird watching sites were identified, with the sampling method based on counting points with a fixed radius of 30 m. 100 species from 33 families and 15 orders were recorded. In the CF, 916 individuals were identified, corresponding to 89 species, and in VS 331 individuals of 54 species, finding significant differences in bird diversity between sampling coverages. The records of Dendrortyx barbatus, Leptotila verreauxi and Vireo griseus stand out for being endemic and classified as endangered and threatened, respectively. Furthermore, Pionus senilis, a threatened species, as well as Falco peregrinus, Micrastur semitorquatus, Passerina ciris, Psarocolius montezuma, Myadestes occidentalis and Amazona albifrons, subject to special protection, were also recorded. This study provides information on how the birds make differential use of two vegetation covers, which can be used to generate sustainable strategies for forest management and conservation.

Clinical and metabolic characteristics of males with early-onset androgenetic alopecia

Background: Men with early-onset androgenetic alopecia (AGA) often have an abnormal hormonal milieu. Objective: To ascertain the clinico-phenotypic characteristics and the prevalence of hormonal and metabolic changes in men with early-onset AGA. Methods: Consecutive male patients less than 30 years of age with a Norwood-Hamilton grade ?3 AGA were recruited in this comparative cross-sectional study. After endocrine evaluation they were classified into two groups, that is, Group A consisting of subjects with an altered hormonal profile and Group B with normal hormonal profiles. The groups were assessed for differences in disease phenotype and severity (Norwood-Hamilton grade), insulin resistance and parameters of metabolic syndrome (ATP III guidelines). Results: Altered hormonal profiles were seen in 34 of the 100 subjects with AGA, while insulin resistance and metabolic syndrome were noted in 44 and 26 respectively. Altered hormonal profiles were significantly associated with insulin resistance and severe alopecia (grade 4 and above Hamilton-Norwood Scale). Insulin resistant Group A patients had a significantly higher prevalence of severe alopecia (>grade 4) (P = 0.0036). The prevalence of metabolic syndrome was similar in both groups. Limitation: The cross sectional study design was a drawback of this study. Further, a control arm without AGA was not included and the sample size of 100 was selected arbitrarily. Conclusion: An altered hormonal profile and insulin resistance was noted in a third of the males with early-onset AGA. Subjects with altered hormonal profiles had a higher prevalence of insulin resistance and were likely to have severe grades of AGA

Creencias Irracionales y Sintomatología Depresiva en Estudiantes Universitarios de Psicología en Honduras

El objetivo de este estudio fue determinar la relación entre creencias irracionales y sintomatología depresiva en estudiantes universitarios de Psicología en Honduras. Se utilizó un enfoque cuantitativo, un alcance descriptivo-correlacional y un diseño no experimental transversal correlacional. La muestra fue de 257 estudiantes universitarios de Psicología de dos universidades hondureñas. Para la recolección de datos se aplicó el Test de Creencias Irracionales y el Inventario de Depresión de Beck-II. Las principales creencias irracionales manifiestas por los estudiantes son culpabilización, altas autoexpectativas, influencia del pasado y evitación de problemas, y alrededor de un tercio sufre sintomatología depresiva de moderada a severa. Los estudiantes varones, menores de 31 años, pertenecientes a una universidad privada y que se encuentran solteros son los que tienen más altas creencias irracionales y mayores niveles de depresión, pero solo hay diferencia estadísticamente significativa entre el grupo etario y la sintomatología depresiva. Además, existe relación significativa entre creencias irracionales y cuatro de sus dimensiones (necesidad de aprobación, altas autoexpectativas, culpabilización e influencia del pasado) con sintomatología depresiva. Es urgente que las autoridades universitarias elaboren programas y servicios institucionales que prevengan y promuevan la salud mental, para disminuir los procesos mentales patológicos que pueden desencadenar problemas como el suicidio.

The objective of this study was to determine the relationship between irrational beliefs and depressive symptoms in university students of Psychology in Honduras. A quantitative approach, a descriptive-correlational scope and a non-experimental correlational cross-sectional design was used. The sample was 257 university students of Psychology from two Honduran universities. For the collection of data, the Irrational Beliefs Test and the Beck-II Depression Inventory were applied. The main irrational beliefs manifested by the students are guilt, high self-expectations, influence of the past and avoidance of problems, and about a third of the students suffer from moderate to severe depressive symptoms. Male students, under 31 years, attending a private university and who are single are those who have the highest irrational beliefs and higher levels of depression, but there is only a statistically significant difference between the age group and depressive symptomatology. In addition, there is a statistically significant relationship between irrational beliefs and four of its dimensions (need for approval, high self-expectations, guilt and influence of the past) with depressive symptoms. It is urgent that university authorities develop programs and institutional services that prevent and promote mental health, to reduce pathological mental processes that can trigger problems such as suicide.

Sleep disturbance and association with social behavior in preschool children with autism spectrum disorder / 中国康复理论与实践

ObjectiveTo explore sleep disturbance in preschool children with autism spectrum disorder (ASD) and analyze the relationship between sleep disturbance and social behavior. MethodsFrom December, 2020 to December, 2022, 221 preschool children with ASD from Beijing Bo'ai Hospital and other two institutes, and 246 healthy preschool children socially recruited were investigated with Children's Sleep Habits Questionnaire (CSHQ). A total of 47 ASD children and 47 healthy children were selected from them to wear a sleep monitoring watch for seven days, while the ASD children were evaluated with Gesell Development Diagnosis Scale (GDDS), Psychoeducational Profile-Third Edition (PEP-3), Autism Diagnostic Observation Schedule-2 (ADOS), Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS) and Social Responsiveness Scale (SRS). ResultsAll the factor-scores were more in the ASD children than in the healthy children (t > 2.491, P < 0.05), except that of daytime sleepiness. The prevalence of sleep disturbance (CSHQ ≥ 41) was 89.6% in ASD children, which was more than that of the healthy children (76.8%) (χ2 = 13.360, P < 0.001). The sleep problems in ASD children included bedtime resistance, sleep anxiety, sleep duration, sleep onset delay, parasomnias and sleep disordered breathing. ASD children were shorter in total bedtime, shorter in total sleep time, longer in sleep latency, longer in awake time and lower in sleep efficiency (|t| > 2.001, P < 0.05), compared with those of healthy children. For ASD children, the total bedtime negatively correlated with GDDS-language, PEP-3-expressive language, PEP-3-communication and PEP-3-maladaptive behaviors (r < -0.300, P < 0.05); the sleep efficiency negatively correlated with total score of CARS (r = -0.365, P < 0.05); sleep latency correlated with GDDS-social, PEP-3-cognitive, PEP-3-expressive language, PEP-3-receptive language, PEP-3-visual-motor imitation, PEP-3-characteristic verbal behaviors, PEP-3-communication, original score of ADOS, ADOS-social affect, and total score of CARS (|r| > 2.90, P < 0.05); and total awake time positively correlated with total score of CARS (r = 0.406, P < 0.05). ConclusionSleep disturbance is prevalent and various in preschool ASD children, and influence their social behaviors.

Thought of Treatment of Orifices Based on Correspondence Between Drugs and Symptoms in Chinese Herbal Classics in Past Dynasties / 中国实验方剂学杂志

ObjectiveTo discuss the thought of treatment of orifices in the Chinese herbal classics in the past dynasties based on the correspondence between drugs and symptoms to guide the clinical treatment based on syndrome differentiation. MethodAll the literature data of Chinese herbal classics were retrieved from the database of the Chinese Medical Dictionary， involving 76 works of Chinese herbal classics and covering representative works from the Han dynasty to the Ming and Qing dynasties. The information on Chines herbal drugs for the treatment of orifices was collected and sorted out. According to Chinese Materia Medica （11th Edition） and Pharmacopoeia of the People's Republic of China （2020 Edition）， the nature， flavor， and meridian tropism of the selected Chinese herbal drugs were statistically analyzed. The pathogenesis elements in the treatment of orifices were classified and counted， and the contents of syndrome differentiation and treatment in various Chinese herbal classics were extracted. ResultIn 76 Chinese herbal classics in the past dynasties， 93 Chinese herbal drugs for the treatment of orifices were selected. The nature of drugs was mainly warm， followed by cold and mild. The flavor was mainly pungent， followed by bitter and sweet. In terms of meridian tropism， drugs mainly acted on the lung meridian， followed by stomach， heart， liver， spleen， and kidney meridians. The pathogenesis elements of orifices could be divided into six categories， i.e.， wind invasion， turbid obstruction and Qi stagnation， water and dampness stagnation， blood stasis and collaterals blockage， heat and toxin damage， deficiency of vital Qi and cold coagulation. ConclusionOrifices are mainly treated with drugs effective in dispelling wind and pathogenic factors， resolving turbidity and removing stagnation， inducing diuresis and eliminating dampness， promoting blood circulation and dredging collaterals， clearing heat and purging fire， tonifying deficiency and dispelling cold， which are used in combination. Eliminating pathogenic factors and dredging， tonifying deficiency and purging excess are the main characteristics of treatment of orifices based on syndrome differentiation， which is in line with the physiological dysfunction state of orifices in losing the function， evil Qi blockage and healthy Qi deficiency.

Analysis of clinical characteristics of 294 acute poisoning patients with gastric lavage / 中华急诊医学杂志

Objective:To describe the current situation of gastric lavage operation and put forward measures for improvement by analyzing the clinical characteristics of 294 patients with gastric lavage in Poisoning Treatment Center of The First Affiliated Hospital of Nanjing Medical University.Methods:The clinical data of 294 patients with acute poisoning and gastric lavage from 2019 to 2021 were collected and analyzed retrospectively, and the related parameters (poison type, gastric lavage volume, poisoning to gastric lavage time, etc.) of each year were compared.Results:A total of 653 poisoning patients underwent gastric lavage from 2019 to 2021, with an average age of (44.2 ±20.1) years, and 134 (45.6%) were male. The main causes of gastric lavage were pesticide poisoning (52.72%) and drug poisoning (42.86%). The volume of gastric lavage was less than 10 L for 43.8% of patients and 10-20 L for 32.7% of patients. Patients with gastric lavage within 60 min after ingestion of poison accounted for 45.3%, followed by 25.8% within 61-120 min. The in-hospital mortality rate was 17.7%. The common complications of gastric lavage were: the incidence of gastrointestinal bleeding (55/121, 45.5%), the incidence of aspiration pneumonia (54/140, 38.6%), and the incidences of electrolyte disorder (21% of low potassium, 29% low calcium, and 10.0% low sodium). Compared with the groups in different years, the proportion of gastric lavage in poisoning was 58.85% vs. 46.60% vs. 32.41%, which decreased year by year, with statistical difference ( P <0.05). And there was no difference in the period from ingestion to gastric lavage and gastric lavage fluid volume. There was an increasing trend in poison types between diquat and other insecticides, but there was no statistical difference. Conclusions:From 2019 to 2021, the most common causes of acute gastric lavage were pesticide poisoning and drug poisoning, and the proportion of diquat and other pesticides showed an overall upward trend. A majority of the patients (71.1%) had gastric lavage within 2 h, and 76.5% of the patients had less than 20 L gastric lavage fluid. In the future, we will further control the amount of gastric lavage fluid and pay attention to the gastric lavage operation of new insecticide poisoning.

Study on the relationship between body image disturbance and depression and anxiety symptoms in pregnant women： a scoping review / 四川精神卫生

BackgroundPsychological problems such as depression and anxiety are common in pregnant women， and many studies have found that body image disturbance is closely related to depression and anxiety symptoms. Still， there is large variability in previous findings. ObjectiveTo review the researches on the relation of body image disturbance to depression and anxiety in pregnant women， and to provide a reference for interventions targeting maternal body image disturbance and depression and anxiety symptoms. MethodsOn January 10， 2023， well qualified literature focusing on the relationship between body image disturbance and depression and anxiety symptoms in pregnant women were searched in PubMed， Embase， CINAHL， Web of Science， China National Knowledge Infrastructure （CNKI）， VIP databases， Wanfang Data Database and China Biology Medicine disc （CBMdisc） from inception to January 1， 2023. The research content， factors influencing body image disturbance and relevant findings were extracted and summarized for analysis. ResultsA total of 14 articles were included in this review. The body image disturbance in pregnant women was manifested predominantly by an excessive concern about body weight and shape， and was affected by demographic characteristics， sociocultural factors， obstetric factors and other factors. Furthermore， body image disturbance significantly predicted the occurrence of depression， and proved a close relationship with anxiety symptoms. ConclusionBody image disturbance seriously affects the physical functioning and psychological status of pregnant women and may further exacerbate the symptoms of depression and anxiety.

Por trás da leptina: uma revisão de literatura / Behind the leptin: a literature review / Detrás de leptin: una revisión de la literatura

A obesidade é uma doença crônica, multifatorial, que afeta todas as idades e classes sociais. Esta comorbidade tem avançado em decorrência de diversos fatores e sua prevalência está ancorada em diferentes dimensões como as biológicas, sociais, históricas, comportamentais, saúde pública e política. O presente estudo tem como objetivo caracterizar o gene da leptina, seu produto e de seus receptores, assim como os mecanismos que corroboram com o desenvolvimento da obesidade e seu envolvimento com distúrbios alimentares. A leptina é uma proteína secretada principalmente nos adipócitos, ela reduz o apetite por meio da inibição da formação de neuropeptídeos relacionados ao apetite, como o neuropeptídeo Y e eleva a expressão de neuropeptídeos anorexígenos, como o hormônio liberador de corticotropina, por isso que os altos níveis de leptina reduzem a ingestão alimentar, em contraste com os níveis baixos que induzem hiperfagia. Como a leptina realiza o controle da saciedade e regulação do gasto energético, o indivíduo com disfunção neste gene não desenvolve essa função corretamente. Isso se deve aos SNPs, que de acordo com estudos aumentam a susceptibilidade à obesidade. Além do mais, a leptina pode estar envolvida com processo patológico de alguns distúrbios alimentares, predispondo o paciente às condições como anorexia nervosa e bulimia.

Obesity is a chronic, multifactorial disease that affects all ages and social classes. This comorbidity has advanced as a result of several factors and its prevalence is anchored in different dimensions such as biological, social, historical, behavioral, public health and political. The present study aims to characterize the leptin gene, its product and its receptors, as well as the mechanisms that corroborate the development of obesity and its involvement with eating disorders. Leptin is a protein secreted mainly in adipocytes, it reduces appetite by inhibiting the formation of appetite-related neuropeptides such as neuropeptide Y and elevates the expression of anorexic neuropeptides such as corticotropin-releasing hormone, so high levels of leptin reduce dietary intake, in contrast to low levels that induce hyperphagia. As leptin performs satiety control and regulation of energy expenditure, the individual with dysfunction in this gene does not develop this function properly. This is due to SNPs, which according to studies increase susceptibility to obesity. Furthermore, leptin may be involved with the pathological process of some eating disorders, predisposing the patient to conditions such as anorexia nervosa and bulimia.

La obesidad es una enfermedad crónica multifactorial que afecta a todas las edades y clases sociales. Esta comorbilidad ha avanzado como resultado de diversos factores y su prevalencia está anclada en diferentes dimensiones, como la biológica, la social, la histórica, la conductual, la salud pública y la política. El objetivo de este estudio es caracterizar el gen de la leptina, su producto y sus receptores, así como los mecanismos que corroboran el desarrollo de la obesidad y su participación en los trastornos alimentarios. La leptina es una proteína secretada principalmente en los adipocitos, reduce el apetito inhibiendo la formación de neuropéptidos relacionados con el apetito, como el neuropéptido Y y eleva la expresión de neuropéptidos anorexógenos, como la hormona que libera la corticotropina, razón por la cual los altos niveles de leptina reducen la ingesta dietética, en contraste con los bajos niveles inducir hiperagia. Como la leptina lleva a cabo el control de la saciedad y la regulación del gasto energético, el individuo con disfunción en este gen no desarrolla esta función correctamente. Esto se debe a los SNP, que según los estudios aumentan la susceptibilidad a la obesidad. Además, la leptina puede estar implicada en el proceso patológico de algunos trastornos alimentarios, predisponiéndose al paciente a condiciones tales como anorexia nerviosa y bulimia.

Prevalence of sleep disturbance in patients with ankylosing spondylitis: a systematic review and meta-analysis

Abstract Background Ankylosing Spondylitis (AS) patients face several challenges due to the nature of the disease and its physical and psychological complications. Sleep disorders are among the most important concerns. Sleep disorders can aggravate the signs and symptoms of the disease and ultimately reduce the quality of patients' lives. This study uses a systematic review and meta-analysis to pool the reported prevalence of sleep disorders among AS patients. Methods To find related studies, the WoS, PubMed, ScienceDirect, Scopus, Embase, and Google Scholar databases were systematically searched without a lower time limit. Heterogeneity among the identified studies was checked using the I2 index, and the Begg and Mazumdar correlation test examined the existence of published bias. Comprehensive Meta-Analysis (v.2) software was adopted to analyze the data. Results In the review of 18 studies with a sample size of 5,840, the overall pooled prevalence of sleep disorders among AS patients based on the random effects method was found to be 53% (95% CI: 44.9-61). The highest and lowest prevalence was in Egypt at 90% and Australia at 19.2%, respectively. Our meta-regression results show that with the increase in 'sample size' and 'year of publication', the overall prevalence of sleep disorders in patients with AS decreases (p < 0.05). Conclusion The results of the present study indicate a high and significant prevalence of sleep disorders among AS patients. Thus, health policymakers and healthcare providers must focus on timely diagnosis and effective educational and therapeutic interventions for the prevention and proper treatment of sleep disorders in this population of patients.

Resilience among pediatric healthcare workers during the COVID-19 pandemic in a tertiary hospital

OBJECTIVES@#Healthcare workers are at the center of the pandemic, dealing with cases while being at risk of acquiring the infection themselves, causing work-related stress. Despite this, they continue reporting for duty. This paper aims to determine the factors that affect resilience of pediatric healthcare-workers in close contact with patients suspected with COVID infection and its association to sleeping disturbance during the first two years of COVID – 19 pandemic in a tertiary hospital in the Philippines.@*METHODOLOGY@#This is a cross-sectional study. Healthcare-workers who render bedside patient care for those suspected or with COVID-19 infection, not diagnosed with any mental health illness, and fit the inclusion criteria were chosen through purposive sampling and asked to answer questionnaires with demographic survey, BRS and PSQI tool.@*RESULTS@#Among 89 participants, females were predominant (60.67% ). Majority were in the 30- 39 age group (44.94%) and are nurses (40.45%) or doctors (39.33%) who were single (76.40%). Many have normal resilience as measured from their BRS scores with an average PSQI per category equal to or exceeded 5.00. The correlation coefficient was at -0.338 (p-value 0.001) between the BRS and PSQI scores, indicating that a significant negative correlation exists between the two scores.@*CONCLUSION@#Normal resilience was reported in the majority of the healthcare workers. All study participants had poor sleep quality as determined in the overall average PSQI score. A negative correlation between resilience and sleep quality was observed, denoting that poor sleep quality can be associated with lower resilience, and vice versa. However, temporality cannot be assumed with this study.

Refractory hypokalemia: a case report

Hypokalemia is a common electrolyte disturbance in hospitalized patients, which prompts appropriate identification of hypokalemia symptoms and signs. As many as 20% of hospitalized patients are found to have hypokalemia. Many hypokalemia patients could also have systemic disease.A 55-year-old woman was presented with weakness, nausea, and vomiting for 2 days before admission. Vomit consisted of water; there was no bloodin the vomit. Defecation was normal; consistency and odor of feces were normal. Patient had diabetes and was already on insulin regiment. Insulin was discontinued during hospitalization since blood sugar was close to lower limit. Electrocardiography (ECG)was within normal limit.Symptoms and signs of hypokalemia may not be readily apparent, as seen in this case. Treatment of hypokalemia should intend not to only replenish potassium, but also to identify underlying cause. Causes include gastrointestinal losses, intracellular shift, renal potassium losses, and inadequate intake.

Incidence of inferior alveolar nerve sensory deficit and intra-operative nerve encounters after advancement of retrognathic mandible – A cross-sectional survey study

Aims and Objectives: The aim of the current cross?sectional study was to conduct a survey among the oral and maxillofacial surgeons of South India regarding their experiences of incidence of inferior alveolar nerve (IAN) neurosensory deficit after bilateral sagittal split osteotomy (BSSO) for correction of mandibular retrognathism and to assess the intra?operative nerve encounters and its effect on the inferior alveolar neurosensory deficit (NSD), 6 months post?operatively. Materials and Methods: A self?administered questionnaire (SAQ) was prepared using Google Forms (Google Inc.) and sent to the prospective participants through various social media outlets such as Facebook, WhatsApp groups etc., of the maxillofacial surgery specialty for a period of 3 months. SAQ from surgeons with more than 5 years of experience in orthognathic surgery were included. Results: The incidence of NSD post?BSSO advancement surgery from 859 cases after 6 months was 15.1% (130). After splitting the mandible, the IAN was seen in the proximal fragment in 472 sites and needed dissection. The nerve was transected and neurorrhaphy was carried out in 26 sites. A Chi?square test was used to analyse the qualitative variables. The IAN was not visible post?osteotomy in 140 sites and in the distal fragment in 1080 sites. These groups had decreased incidence of NSD. The NSD was significantly higher in cases where the nerve was transected and sutured, P value <0.001 as compared with the other nerve status, followed by the nerve in the proximal fragment needing dissection. Conclusion: The IAN status intra?operatively can be assumed to have a significant role in persisting NSD

Brugada syndrome unmasked by fever and paradoxical lower degree of dromotropic disturbance in the right ventricular outflow tract

Brugada syndrome (BrS) is an inherited clinical-electrocardiographic arrhythmic entity with an autosomal dominant genetic pattern of inheritance or de novo variant. The syndrome has low worldwide prevalence, but is endemic in Southeast Asian countries (Thailand, Philippines and Japan). The BrS is a subtle structural heart disease (SHD), and the diagnosis is only possible when the so-called type 1 Brugada ECG pattern is spontaneously present or induced for example with fever. Repolarization-depolarization disturbances in BrS patients can be caused by genetic mutations, abnormal neural crest cell migration, low expression of connexin-43 gap junction protein, or connexome disturbances. A recent autopsy study revealed increase in biventricular collagen with myocardial fibrosis when compared with control subjects although the main affected cardiac territory is the right ventricular outflow tract (RVOT). In this location, there is abnormally low expression of significant connexin-43 gap junction responsible for the electro-vectorcardiographic manifestations of terminal QRS conduction delay in the right standard precordial leads (V1-V2), high right precordial leads (V1H-V2H), as well as in the unipolar aVR lead ("the forgotten lead"). Based on their location, these leads reflect the electrical activity of the RVOT.

A síndrome de Brugada (SBr) é uma entidade arrítmica clínico-eletrocardiográfica hereditária com padrão genético autossômico dominante de herança ou variante de novo. A síndrome tem baixa prevalência mundial, porém sendo endêmica no Sudeste Asiático (Tailândia, Filipinas e Japão). A SBr é uma doença cardíaca minimamente estrutural, sendo o diagnóstico só possível na presença do chamado padrão ECG de Brugada tipo 1 espontâneo ou induzido, por exemplo, a febre. Os distúrbios de repolarização-despolarização em pacientes com SBr podem ser causados por mutações genéticas responsáveis pela migração anormal de células da crista neural, baixa expressão "gap junctions" conexina-43 ou distúrbios do conexoma. Um estudo recente de autópsia revelou aumento do colágeno biventricular com fibrose miocárdica quando comparado aos controles, embora o principal território cardíaco afetado seja a via de saída do ventrículo direito (VSVD). Nessa área, há menor expressão da conexina-43, o que se traduz no ECG-VCG por atraso final de condução do QRS nas derivações precordiais direitas (V1-V2), precordiais direitas altas (V1H-V2H), bem como na derivação unipolar aVR ("a derivação esquecida"). Com base em sua localização, esses eletrodos refletem a atividade elétrica da VSVD

McKittrick-Wheelock syndrome secondary to rectal adenocarcinoma

Introduction: McKittrick-Wheelock syndrome is a rare condition that arises from a hypersecretory state secondary to large colorectal tumors, mainly villous adenomas, leading to an electrolytic disorder associated with chronic diarrhea that usually persists for years. It is a relatively unknown disease that can lead to severe complications such as acute kidney injury, severe hyponatremia, and hypokalemia. In fact, it causes death in most untreated cases. Surgical removal of the tumor is the most successful treatment, and symptoms tend to disappear after proper management. Case Report: A 62-year-old man with a 2-year history of mucoid diarrhea preceded by abdominal pain presented with acute kidney injury, hyponatremia, and hypokalemia. A digital rectal examination and sigmoidoscopy were performed, and revealed a large laterally-spreading tumor in the rectum. Further investigation showed a rectal tubulovillous adenoma with secondary McKittrick-Wheelock syndrome. An anterior resection of the rectum with a colonic J-pouch and a diverting ileostomy were performed, and the patient improved with the resolution of the renal failure and electrolyte disturbances. The histopathological analysis revealed an invasive rectal adenocarcinoma. Discussion: McKittrick-Wheelock syndrome is a condition with a low incidence that needs early intervention and proper diagnosis. It is of extreme importance that this disease is included in the differential diagnoses for chronic diarrhea associated with an electrolytic disorder. (AU)

Depresión, desregulación emocional y estrategias de afrontamiento en adolescentes con conductas de autolesión / Depression, emotional dysregulation and coping strategies in adolescents with self-injurious behaviors

Resumen En México, el estudio de la autolesión cuenta con pocas investigaciones, y menos si se trata de estudios que conformen posibles modelos explicativos. Teniendo esto en cuenta, en el presente trabajo se planteó como objetivo conocer la relación de la autolesión con la depresión, la desregulación emocional y los estilos de afrontamiento, con el fin de generar un modelo explicativo de la problemática. El estudio se realizó a partir de un diseño cuantitativo, transversal y con alcance explicativo, y se contó con una muestra de 5835 adolescentes (M edad = 11-15 años) inscritos en 62 secundarias públicas del estado de Sonora. Se realizaron regresiones logísticas para el análisis de los datos, y como resultado se encontró que, para los estudiantes con autolesión severa (3.54 %), el modelo explica el 61 % de la varianza en los datos (R1 de Nagelkerke = .61) y clasifica correctamente al 84.1 % de los participantes; mientras que, en la autolesión leve (5.29 %), el modelo explica el 72 % de la varianza en los datos (R2 de Nagelkerke = .72) y clasifica correctamente al 88.2 % de los estudiantes. Asimismo, las dimensiones de depresión mostraron el mayor nivel explicativo (cognitiva-afectiva, somática) y correlaciones positivas con la desregulación emocional y el estilo de afrontamiento de evitación, así como correlaciones negativas con el estilo de afrontamiento de aproximación. Al final se discute respecto a la importancia de las variables independientes para futuras investigaciones, y sobre los resultados anómalos y otros datos de interés.

Abstract In Mexico, there is little research on the study of self-injury and even less on possible explanatory models. With this in mind, this study aimed to determine the relationship between self-injury and depression, emotional dysregulation, and coping styles, to generate an explanatory model of the problem. The study was carried out using a quantitative, cross-sectional, explanatory scope, design and a sample of 5835 adolescents (Mage = 11-15 years) enrolled in 62 public high schools in the state of Sonora. Logistic regressions were performed for data analysis, and as a result it was found that, for students with severe self-injury (3.54 %), the model explains 61 % of the variance in the data (Nagelkerke's R2 = .61) and correctly classifies 84.1 % of the participants; whereas, in mild self-injury (5.29 %), the model explains 72 % of the variance in the data (Nagelkerke's R2 = .72) and correctly classifies 88.2 % of the students. Likewise, the depression dimensions showed the highest explanatory level (cognitive-affective, somatic) and positive correlations with emotional dysregulation and avoidance coping style, as well as negative correlations with approach coping style. At the end, the importance of the independent variables for future research is discussed, as well as anomalous results and other data of interest.

Obesity effects on sleep quality with anthropometric and metabolic changes

SUMMARY OBJECTIVE: Obesity is one of the etiological factors of sleep disorders (e.g., obstructive sleep apnea and restless leg syndrome). The aim of this study was to determine the effect of obesity on sleep quality by using the Pittsburgh Quality İndex and Berlin Question are and evaluate the association of sleep with anthropometric and metabolic parameters. METHODS: A total of 76 patients (41 females and 35 males) between the ages of 18 and 70 years with a body mass index >30 kg/m2 were included in this study. Homeostatic model assessment-insulin resistance, hemoglobin A1c, alanine aminotransferase, aspartate transaminase, total cholesterol, low-density lipoprotein, triglyceride, high-density lipoprotein, and thyroid-stimulating hormone levels were analyzed. Sleep quality was evaluated with the Pittsburgh Sleep Quality Index, Berlin Questionnaire, and the Restless Leg Syndrome Questionnaire. RESULTS: A significant correlation was observed between Pittsburgh sleep quality index and body mass index, neck circumference, body fat index, muscle mass, hip and waist circumference, hemoglobin A1c, and homeostatic model assessment-insulin resistance (ps<0.005). The Pittsburgh sleep quality index median (2.5-97.5 percentile) value was 8 (2-18.6) in the patient group and 3.5 (0.1-7.9) in the control group (p<0.0001). Body mass index was found to be the predictor on Pittsburgh sleep quality index (R2=0.162, F=3.726, analysis of variance p=0.008). Notably, 88% (67) and 95% (57) of the poor sleepers were found to be at high risk for obstructive sleep apnea according to Berlin Questionnaire and Pittsburgh Sleep Quality Index, respectively. Also, the frequency of restless leg syndrome was 45% in obese individuals. CONCLUSIONS: We observed a significant correlation between Pittsburgh sleep quality index and the anthropometric and metabolic parameters. Also, the frequency of obstructive sleep apnea and restless leg syndrome was 88% and 45%, respectively, in obese individuals.

Diversidad de escarabajos coprófagos (Coleoptera: Scarabaeidae) en tres zonas urbanizadas del Caribe colombiano / Diversity of dung beetles (Coleoptera: Scarabaeidae) in three urban areas from Colombian Caribbean

Resumen En el presente trabajo se estudia la diversidad de escarabajos coprófagos en tres zonas urbanizadas del departamento de Sucre, Colombia, cada una con características ecológicas distintas. Los individuos fueron capturados con trampas de caída cebadas. Se analizaron el esfuerzo de muestreo, las curvas de rango-abundancia y los índices de diversidad alfa y beta. Se capturaron 710 individuos, agrupados en nueve géneros y 13 especies. El análisis de completitud arrojó valores por encima del 97%. El ensamble más diverso en cualquiera de los tres órdenes de "q" se encontró en la zona que alberga edificaciones, jardines y un parche de bosque de vegetación secundaria, seguido por una zona de pastizales, con pocas edificaciones; el ensamble de menor diversidad correspondió a la zona rodeada de edificaciones y con escasa cobertura vegetal. El índice de Sorensen-Dice arrojó una similitud total entre las tres zonas del 38%. Las curvas de rango-abundancia mostraron mayor equidad de especies en la zona más diversa. Los resultados indicaron que la composición del ensamble de escarabajos depende de las condiciones ambientales y el grado de urbanización. Así mismo, se evidenció que algunas especies pueden tener alta adaptabilidad y que algunas de ellas corren el riesgo potencial de presentar eventos de extinción local.

Abstract In this paper, diversity and composition of dung beetles assemblage was study in three urbanized areas with different ecological characteristics from Sucre department , Colombia. Individuals were captured with baited pitfall traps. Sampling effort, range-abundance curves, alpha and beta diversity indices were estimated and compared among the sites. Seven hundred ten individuals grouped into nine genera and 13 species were recorded. The completeness analysis yielded values above 97%. The most diverse assemblage in any of the three orders of "q" was found in the site with a mixture of buildings, gardens, and a patch of secondary vegetation forest, followed by the site with few facilities and open green spaces, and the least diverse site corresponded to the area surrounded by buildings with little vegetation cover. Sorensen-Dice index similarity among the three sites was 38%. The range-abundance curves showed higher species equitability in the most diverse site. The results show that the beetle assemblage composition depends on environmental conditions and the degree of urbanization. It was also evident that some species have high adaptability to urban spaces and others are potentially at risk of local extinction events.

Body image flexibility: measurement, correlated factors and intervention / 中华行为医学与脑科学杂志

Body image flexibility (BIF) is the specific type of psychological flexibility in the research field of body image, which reflects the ability to experience negative body image and related events in an open and acceptive way, and take actions consistent with one's values. Body image is actually not stable. If negative body image could not be adjusted effectively in time, it would develop into body image disturbance (BID), which is one of the core symptoms and psychopathological mechanisms of eating disorder (ED) and body dysmorphic disorder (BDD). BIF is one of the important factors in this development path, gaining more and more attention as a protective factor for body image. So far, most studies focus on eating disorder patients and related sub-clinical populations. Body image-acceptance and action questionnaire is the most widely used measurement. BIF is related to some sample characteristics, such as gender, age and body size.Cultural context also has an impact on it.Positive and negative body image and eating disorder pathological characteristics are also strongly associated with BIF. As to the intervention, the application of mindfulness, acceptance and compassion in treatment may improve BIF. Future studies need to improve the research methods and designs, and pay attention to other samples. More specific interventions need to be developed, of which the therapeutic mechanisms also need to be explored.
