OBJECTIVE: To determine the incidence of perioperative delirium (POD) at the Hospital nacioanl Arzobispo Loayza, from October to December 2021.   METHODS: Qualitative and prospective observational study, carried out in a population of 910 patients, in which the AMT Test Confusion Assessment Method (CAM) and the Pfeiffer questionnaire (Short Portable Mental Status Questionnaire, SPMSQ) were applied. We used Chi2 to demonstrate the existence of association and Cramer's V and Phi tests to quantify the intensity of said relationship if it existed.   RESULTS: Of the total of patients (910), 18.46% presented perioperative delirium. Sex and religion do not influence this. Age does influence the presentation of POD since 50% (145) of the patients 61 years of age or older presented it, unlike those between 36 -60 years of age only 5.31% and those of 18 - 35 only 0.88% presented POD. According to the level of education: 100% with no education, 73.1% with primary education, 18.5% with secondary education  and 5.8% with higher education, presented DPO. According to the anesthetic technique, POD was found in 28.9% (60) of the spinal type with sedation, 22.4% (11) of the epidural type with sedation, 16.7% (83) of the General TIVA TCI type, 12.9% (4) of the Block type with sedation, 9.5% (10) of the General balanced type; for the types of general anesthesia manual TIVA, General Multimodal and Spinal anesthesia without sedation there were no cases of POD. According to the operative time: 100% (9) of the patients with more than 6 hours of operative time, 27.1% (38) of the patients who have 3 to 6 hours of operative time and 16.5% (121) of the patients who have 1 to 3 hours of operative time presented cases of POD.   According to hospitalization time prior to surgery: 48% (36) of patients with hospitalization time of 16 to 30 days, 20.5% (26) of patients with hospitalization time of 8 to 15 days and 16% (97) of the patients with hospitalization time of 3 to 7 days presented POD. According to the presence of comorbidities: 51.6% (16) with AHT and RD, 41.7% (30) with Diabetes and 40.8% (20) with AHT and DM2 present POD.     According to the presence of dementia: 100% (6) of the patients with a history of dementia and 17.9% (162) of the patients with no history of dementia presented POD. According to psychiatric history, 68.4% (13) of those who did have a history of psychiatric disorder and 17.4% (155) of those who did not have a history of psychiatric disorder presented POD. According to history of psychiatric treatment: 100% (6) of those who do have a history of treatment and 17.9% (162) of those who do not have a history of psychiatric treatment presented POD. According to the pre-surgical and post-surgical PFEIFFER questionnaire: 100% of those with mild, moderate or severe cognitive impairment according to the PFEIFFER PRE QX questionnaire presented POD. According to diagnosis of pre-surgical and post-surgical delirium: 100% presented POD.   CONCLUSIONS: There is no association between sex and religion and the presentation of POD. If there is an association between age, educational level, type of anesthesia, operative time, hospitalization time prior to surgery, comorbidities, history of dementia, history of psychiatric disorder, history of psychiatric treatment, pre-, post-surgical Pfeiffer questionnaire, pre-surgical delirium and post-surgical delirium and the presentation of POD,

Introduction: The COVID-19 pandemic has a great impact on children's health. This study describes the characteristics of hospitalized children at the San Borja National Children's Health Institute in Perú. Methods: This was a retrospective study of patients with a confirmed diagnosis of COVID-19 from March to July 2020. Demographic, clinical, laboratory, radiological, and treatment information were collected. Data analysis included descriptive statistics and bivariate analysis to determine differences between patients in general wards and the intensive care unit (ICU).   Results: We included 91 patients, 33 being females (36.3%). The most affected age group was children > 2 years of age (63 cases) with a median age of 6 years (IQR 3-10), and 61.5% were from Lima. The previous contact was determined in 30.8% of cases. A positive SARS CoV-2 PCR result was obtained in 50.6%. The presence of comorbidity was 53.8%. The most frequent symptoms were: fever (39.6%), general malaise (23.1%), cough (19.8%), and respiratory distress (14.3%). The presence of multisystem inflammatory syndrome in children (MIS-C) was confirmed in 6 patients. Antibiotics were administered in 76.9%. The most frequent radiological pattern was bilateral interstitial infiltrates (57.7%). Mortality was higher in patients in the ICU than in the hospitalization ward (27.3% vs. 4.3%, respectively; p = 0.020)   Conclusions: COVID-19 in children presents mild and moderate clinical manifestations. The presence of comorbidity is an important factor for hospitalization, and mortality is high upon admission to critical care units.

Objective: To develop a systematic review and meta-analysis to determine the association between hypertriglyceridemic waist (CHTG) and arterial hypertension (HBP) in adults. Materials: The present study is a systematic review (SR) with meta-analysis of analytical cross-sectional observational studies. Search strategies will be used in different databases, which will be Pubmed, SCOPUS, Web of Science, Embase. The qualitative analysis was presented in a table with the characteristics of each study. For quantitative analysis, random-effects meta-analysis was performed due to the heterogeneity of the studies. These variables were compared using Odds Ratios (OR) as a measure of association with their corresponding 95% confidence interval. Results: Five studies were included for statistical analysis. Overall, a statistically significant association was found between both variables (OR: 1.36; 95% CI 1.07 to 1.71). In turn, there was a high heterogeneity (I squared 92%). Conclusions: This SR found that CHTG is associated with the presence of hypertension. However, given the few studies found, it is recommended to carry out more primary studies with a prospective design before carrying out a next SR on the subject, and with standardized cut-off points to make a more homogeneous comparability.

Introduction: Maytenus macrocarpa (MM) "Chuchuhuasi" is a native plant from the Amazon region of South America, widely used in traditional medicine due its anti-inflammatory, analgesic and anti-tumor properties. However, its effects on reproductive physiology and male fertility have not been elucidated. Methods: Preclinical experimental study of cases and controls.  Male mice with eight weeks from birth were administered orally for 70 days (two spermatogenic cycles) an aqueous extract MM: GC (n = 8) 0 mg / kg body weight (bw) control group and treated group GT (n = 8) 1000 mg / kg bw. Later the animals were euthanized, the reproductive organs were weighted, also motility and sperm count were recorded. During the days 60 or 65 of treatment, males were mated and pregnant females were sacrificed in the fourth day of pregnancy for evaluating development, quality and degree of blastulation. Results: The weights of reproductive organs did not differ significantly between the two groups (p> 0.05). However, progressive motility (32.81 vs. 15.27 ± 4.17% ± 2.08%) and sperm count (7.75 ± 0.34 x 106 / ml vs. 2.56 ± 0.42 x 106 / ml) decreased significantly between GC and GT, respectively. 87.5% (7/8) of the pregnant mice produced 15 litters (GC) and only 50% (4/8) of the pregnant GT yields 4 litters. However, no significant differences were found in the percentage of blastocyst stage embryos, good quality embryos, or embryos with greater than 50% the size of the embryo between the two groups (p> 0.05) blastoceles. Conclusion: the aqueous extract of Maytenus macrocarpa (1000 mg/kl) could have possesses anti-reproductive action in male mice.

Objective: To identify the factors associated with the interference of gynecological cancer screening in women aged 25-69 years, according to the Demographic and Family Health Survey (ENDES) for the years 2019 and 2020. Materials and methods:  Quantitative, observational, analytical cross- sectional study. It was a secondary database analysis obtained by ENDE for the years 2019 and 2020. Generalized linear Poisson family crude and adjusted models were used to estimate the association. The measure of association. The measure of association used was the adjusted prevalence ratio (Rpa) with 95% confidence interval (95% CI). Results: We worked with a total of 18,113 women aged 25-69 who were interviewed at the ENDES 2019-2020. In the descriptive analysis, it is observed that 19.3% did not take a PAP smear (PAP) and 53.6% did not perform “screening for breast cancer”. Women with a primary education level have 19% and 58% more opportunities to present interference for taking PAP and screening for breast cancer respectively (RPa: 1,19, 95% CI 1.08-1,31 and RPa:1.58, 95% CI 1:51 – 1:64). Living in the jungle increases 56%and 20%more chance of presenting interference for taking PAP and screening for breast cancer respectively (RPa: 1.46, 95% CI 1.42-1.71 and RPa: 1.20, 95% CI: 1.15- 1.25). The level of knowledge increases the interference for taking PAP and screening for breast cancer by 43% and 3% respectively (RPa: 1.43, 95% CI: 1.34- 1.54 and RPa: 1.03, 95% CI:1.00 -1.06) Conclusions: Sociodemographic, sociocultural and economic factors have a marked influence on the performance of gynecological cancers such as cervical cancer and breast cancer, so it is necessary to implement strategies to promote the prevention of these pathologies.

A 46-year-old man with long-standing, poorly controlled diabetes is hospitalized for right knee monoarthritis after trauma. His clinical evaluation found joint deformity, synovitis in the right knee and absence of multiple toes due to a history of amputation. With the radiological evaluation that showed bone destruction and the synovial fluid analysis that ruled out infectious causes and microcrystal arthritis, the diagnosis of Charcot neuroarthropathy of the knee was made. Conservative management was indicated with the use of a felt insole for unloading and the use of a walker, the case being followed up to define behavior according to evolution. Despite being rare, it is important to consider Charcot neuroarthropathy in all diabetic patients with monoarthritis of the knee, in order to make an early diagnosis and avoid important complications and sequelae, always ruling out infectious causes and arthritis due to microcrystals.

Facelift, currently, is one of the most demanded aesthetic procedures and considered as the Ultimate Facial Rejuvenation Surgery. The purpose of this present technique is to offer an alternative surgical procedure of reduced scars, limited to the peri-auricular area, easily reproducible, without the need of extended incisions far beyond the retro-auricular sulcus neither the need of flaps for the temporal region. Our technique is based on a block reposition of the pre auricular area, cervical flaps movilization and rotation of a retro auricular flap, avoiding flaps and incisions in the temporal and occipital region; therefore, minimizing visible scars (occipital pre-pilose scar), wide-tissue undermining, and in addition reducing the risk of damaging nerve structures with less recovery time for our patients, achieving natural and long lasting results.

Heart disease is the cause of sudden death in more than 80% of cases. Ischemic heart disease is the cause for 90% of all sudden cardiac deaths, while in the remaining 10% of cases, heart diseases have a hereditary origin and comprise a wide spectrum of disorders that include cardiomyopathies and channelopathies. The aim of this review is to highlight the importance of genetic counseling for patients with hereditary cardiovascular disease and its evaluation by a multidisciplinary team.

Intoxications in the pediatric population account for a significant portion of the causes of care in emergency services, but they are also fatal in many cases in our country.   Exposure to a toxic or poison and its adverse effects can become medical emergencies of great magnitude, which is why many authors consider them "multiple traumas of chemical origin."   This is why the management of an intoxicated pediatric patient has a unique approach due to the diagnostic challenge that it represents. Timely and systematized care of a pediatric patient in the context of poisoning can represent the success of timely care, correct assessment, and an adequate care process. The objective of this work is to present a general approach for the intoxicated pediatric patient regarding the initial management, the approach, and the clinical data that can guide us in the emergency department when faced with an intoxicated pediatric patient.
