Abstract
Obesity is a global health problem. Its worldwide prevalence has tripled between 1975 and 2016, reaching a prevalence in Chile of 34.4%, according to the National Health Survey 2016-2017. If this condition corresponds to a risk factor or primary disease is a widely discussed issue. It is recognized as a disease by the American Medical Association and World Health Organization, based on its metabolic and hormonal features, such as dysregulation of appetite, abnormal energy balance and endocrine dysfunction, among others. Its main environmental risk factors are the consumption of ultra-processed foods and sedentariness. Preventive measures at the population level are fundamental, emphasizing promotion and prevention using a transdisciplinary approach. The individual approach in the management of obesity should improve the quality of life, avoid early mortality, reduce cardiovascular risk, and reduce the progression to type 2 diabetes and incidence of cancer. Thus, an adequate management and control of obesity would have a great impact in our society.

Abstract
Background The frequency of intra-amniotic infection/inflammation (IAI/I) in patients with midtrimester cervical insufficiency is up to 50%. Our purpose was to determine the perinatal outcomes of cervical cerclage in patients with acute cervical insufficiency with bulging membranes, and to compare the admission-to-delivery interval and pregnancy outcomes according to the results of amniotic fluid (AF) analysis and cerclage placement. Methods This was a retrospective cohort study including singleton pregnancies with cervical insufficiency between 15 and 26.9 weeks in two tertiary health centers. IAI/I was defined when at least one of the following criteria was present in AF: (a) a white blood cell (WBC) count >50 cells/mm3; (b) glucose concentration <14 mg/dL; and/or (c) a Gram stain positive for bacteria. Three different groups were compared: (1) absence of IAI/I with placement of a cerclage; (2) amniocentesis not performed with placement of a cerclage; and (3) IAI/I with or without a cerclage. Results Seventy patients underwent an amniocentesis to rule out IAI/I. The prevalence of IAI/I was 19%. Forty-seven patients underwent a cerclage. Patients with a cerclage had a longer median admission-to-delivery interval (33 vs. 2 days; P < 0.001) and delivered at a higher median gestational age (27.4 vs. 22.6 weeks; P = 0.001) than those without a cerclage. The neonatal survival rate in the cerclage group was 62% vs. 23% in those without a cerclage (P = 0.01). Patients without IAI/I who underwent a cerclage had a longer median admission-to-delivery interval (43 vs. 1 day; P < 0.001), delivered at a higher median gestational age (28 vs. 22.1 weeks; P = 0.001) and had a higher neonatal survival rate (67% vs. 8%; P < 0.001) than those with IAI/I. Conclusion The pregnancy outcomes of patients with midtrimester cervical insufficiency and bulging membranes are poor as they have a high prevalence of IAI/I. Therefore, a pre-operative amniocentesis is key to identify the best candidates for the subsequent placement of a cerclage.

Abstract
Trophoblast cells are often compared to highly invasive carcinoma cells due to their capacity to proliferate in hypoxic conditions and to exhibit analogous vascular, proliferative, migratory, and invasive capacities. Thus, genes that are important for tumorigenesis, such as forkhead box M1 ( FOXM1) may also be involved in processes of trophoblast invasion. Indeed, we found Foxm1 protein and messenger RNA (mRNA) levels decreased as gestational age increased in rat's placentae. Accordingly, when mimicking early placental events in vitro, protein and mRNA expression of FOXM1 increased from 21% to 8% O2, reaching its highest expression at 3% oxygen tension, which reflects early implantation environment, and dropping to very low levels at 1% O2. Remarkably, FOXM1 silencing in JEG-3 cells was able to significantly decrease migration by 27.9%, in comparison with those cells transfected with control siRNA. Moreover, angiogenesis was compromised when conditioned media (CM) from FOXM1-siRNA -JEG-3 (3% O2) was added to human umbilical vein endothelial cells (HUVEC) cells; however, when CM of JEG-3 cells overexpressing FOXM1 at 1% O2 was added, the ability of HUVEC to form tubule networks was restored. Additionally, quantitative real-time polymerase chain reaction (PCR) assays of FOXM1 knockdown and overexpression experiments in JEG-3 cells revealed that the depletion of FOXM1 at 3% O2 and overexpression of FOXM1 at 1% O2 led to downregulation and upregulation of vascular endothelial growth factor transcriptional (VEGF) levels, respectively. Conversely, we also observed deregulation of FOXM1 in placentae derived from pregnancies complicated by preeclampsia (PE). Therefore, we demonstrate that FOXM1 may be a new regulatory protein of early placentation processes and that under chronic hypoxic conditions (1% O2) and in patients with severe PE, its levels decrease.

Abstract
BACKGROUND Gonyautoxin are phycotoxins, whose molecular mechanism of action is a reversible block of the voltage-gated sodium channels at axonal level, impeding nerve impulse propagation. OBJECTIVE To evaluate clinical efficacy of gonyautoxin in the treatment of patients with chronic tensional-type headache. METHODS Open trial from September 2004 to 2005 in Hospital Clínico Universidad de Chile. Twenty-seven patients with chronic tension-type headache were locally infiltrated with gonyautoxins (50 micrograms) in ten sites considered as pain trigger points in a fixed infiltration protocol. In each site, a volume of 200 microlitres was injected. EMG recording was performed before and immediately after infiltrations. Main outcome measures are where a significantly drop-off in acute headache pain score occurs and number of days without headache pain. RESULTS No side effects were detected in the follow-up period. From base line of 2 weeks, 19 patients of 27 (70%) are the successfully responders to the treatment. They showed the remarkable immediate effect after infiltration demonstrated by trapezium EMG recording. Patients reported a fall in pain score 5 minutes post-injection from 5.0 +/- 2.8 to 1.6 +/- 1.6 (mean +/- SD). The responder showed an average of 8.1 +/- 9.9 weeks of headache pain-free, all of them without a second infiltration or use of any additional analgesic medication. DISCUSSION The therapeutic properties of gonyautoxin local infiltration in chronic tension-type headache patients are shown to be safe and effective. This report describes a new therapy for chronic tension-type headache involving local infiltrations of gonyautoxins. The immediate headache pain relief effect shown only minutes after toxin infiltrations were the most remarkable feature of this protocol. This is the first gonyautoxins testing report in the treatment of chronic tension-type headache.

Abstract
BACKGROUND Hispanics have a greater incidence of stroke and prevalence of intracranial atherosclerosis than whites. AIM To study the prevalence of extracranial atherosclerosis among patients admitted to a hospital with an ischemic stroke. MATERIAL AND METHODS A prospective study in stroke patients admitted to a Neurology ward in a University Hospital. All were subjected to a CT scan, carotid duplex-Doppler ultrasonographic examination with Doppler measurement of blood flow velocity, permeability and plaques. Cardiac emboli were searched with transthoracic and transesophageal echocardiography. RESULTS One hundred ten patients (39 women), aged 67.5 +/- 11.4 years old were studied. Stroke was atherothrombotic in 46 (41.8%), embolic in 30 (27.3%), lacunar in 27 (24.6%) and of other type in 7 (6.4%). Ninety two patients (84.4%) had high blood pressure, 38% had high cholesterol levels, 35% had a cardiac disease and 26% were smokers. Thirty five subjects (31.8%) had a normal carotid ultrasonography, 46 (41.8%) had mural plaques, 16 (14.5%) had multiple plaques without occlusion, 13 (11.8%) had a partial occlusion and 7 (6.4%) had a total occlusion. Logistic regression analysis disclosed no significant relationship between stroke types and carotid atherosclerosis. Age was the only significant predictor for carotid atherosclerosis. CONCLUSIONS The prevalence of severe carotid atherosclerosis in this group of stroke patients was less than expected.

Abstract
BACKGROUND This study was undertaken to analyze the local control rates and survival of patients undergoing endoscopic laser surgery for squamous cell carcinoma of the larynx as a salvage procedure for recurrent tumors after radiotherapy. METHODS Twenty-four patients underwent endoscopic laser surgery for radiation failure at our hospital from 1988 to 1995. All patients were men, between 45 and 88 years old. The localization of the recurrence was in the supraglottis in 3 cases and in the glottis in 21 cases. The postirradiation recurrences were staged rT1 in 18 patients and rT2 in 6 patients. RESULTS Local recurrence after laser surgery developed in six patients (25%) who had a total laryngectomy. Voice preservation was thus achieved in 75% of patients. No patient died because of the laryngeal cancer, and the observed 5-year survival rate was 76%. CONCLUSIONS These results indicate that in selected cases, endoscopic laser surgery may be used successfully for treating radiation failure of early laryngeal carcinomas.

Abstract
Hyperhomocysteinemia is an important cardiovascular risk factor. Serum homocysteine levels are specially dependent on folate nutritional status. In addition, the oxidative modification of low-density lipoproteins (LDLs) in the endothelial microenvironment is a damaging factor that can be modified with fat-soluble antioxidant vitamins. The present study was done to assess the effect of a supplementation of folic acid and antioxidant vitamins on homocysteine levels and in vitro LDL oxidation in patients with coronary artery disease. Twenty-three patients with angiographically proven coronary artery disease were given supplements for 15 d consisting of one capsule twice a day of a multivitamin preparation containing 0.65 mg folic acid, 150 mg alpha-tocopherol, 150 mg ascorbic acid, 12.5 mg beta-carotene, and 0.4 microgram vitamin B12. Serum lipids, vitamin and homocysteine levels, and in vitro LDL oxidation were measured before and after the supplementation period. During the supplementation period, serum folate levels increased from 5.0 +/- 1.5 to 10.8 +/- 3.8 ng/mL (P < 0.001), vitamin B12 increased from 317.4 +/- 130.4 to 334.5 +/- 123.8 pg/mL (P < 0.05), and alpha-tocopherol increased from 8.2 +/- 5.1 to 13.7 +/- 7.9 mg/L (P < 0.001). Serum homocysteine levels decreased from 8.7 +/- 4.3 to 6.3 +/- 2.2 mumol/L (P < 0.001). In vitro LDL oxidation decreased from 2.6 +/- 1.1 to 1.6 +/- 1.1 nmol malondialdehyde/mg protein (P < 0.001). In comparing patients with healthy controls, basal levels of folate were lower in the patients, whereas vitamin B12, alpha-tocopherol, and homocysteine levels were similar. No changes in serum lipid levels or body weight were observed. In conclusion, a short-term supplementation with folic acid and antioxidant vitamins can reduce serum homocysteine levels and in vitro LDL oxidation in patients with coronary artery disease.

Abstract
UNLABELLED We studied 67 patients with bladder cancer in stage T1, with terminated BCG treatment and in pursuit. No stage Ta neither carcinoma in situ was included. The protocol was: beginning of treatment upon retiring vesical catheter, instilation of 1 mg of liofilized BCG vaccine (16 x 10(6) bacilles) in 40-50 ml of intravesical saline solution. A weekly instilation during the first month. An instilation each 15 days during the second and third month and one monthly until complete 12 months of treatment. Also was carried out an study of T lymphocites and cytokines. RESULTS The average followup of the 67 patients treated was 51.3 months. 17 patients relapses (25.4%). A 33% were grade 3 and 27% grade 2. Like complications there was a case of inguinal TBC adenititis, 2 TBC prostatitis, 2 TBC cistitis and 5 cases of slight disuric syndrome. The study of subpopulations of lymphocites in peripheral blood demonstrated a significant increase of CD3 and CD4/CD8 ratio. The interleukin 2 measurement in serum also increased significantly after the BCG instilations. CONCLUSIONS Our protocol gets similar results to the higher doses, but with minimal complications diminishing the relapses of the tumors in stage T1. A monthly maintenance dose would help to maintain immunity.

Abstract
We assessed the effect of zinc supplementation on growth velocity in 79 children and adolescents (48 males, 38 females) with idiopathic short stature. Their height-for-age was < 5th percentile (NCHS standards) and their weight-for-age was normal. Patients were assigned randomly to a supplemented group (S) to receive Zn 10 mg/day or to a placebo (P) group, according to gender and age, and were followed-up for 12 months using a double-blind design. Weight, height, armspan, length of lower segment and plasma and hair concentrations of Zn were measured at 0, 3, 6 and 12 months. On admission and at 6 months, energy, protein, dietary fiber and zinc intakes were similar for groups S and P; mean zinc intake was < 6.5 mg/day. No differences were found in plasma zinc, hair zinc, weight, armspan or lower segment increments. Pre-adolescent males in group S had a significantly greater increase in stature compared with group P (6.2 +/- 2.1 versus 4.5 +/- 1.2 cm/year p < 0.025); z score improved from -2.42 to -2.24 in group S and from -2.63 to -2.61 in group P. For adolescent males, the difference was also significant (8.3 +/- 1.5 versus 6.2 +/- 2.1 cm/year; p < 0.025). No differences were noted in females. In Chilean male schoolchildren and adolescents with idiopathic short stature, zinc supplementation increases growth velocity over a 12-month period.

Abstract
Levels of prostatic specific antigen may be modified with procedures over the prostatic gland. We measured this antigen in 36 hospitalized patients before and immediately after a digital rectal examination. Antigen levels were 8.3 +/- 21.3 ng/ml before and 13.8 +/- 27.5 ng/ml after the examination (NS). It is concluded that digital rectal examination did not modify antigen levels in our sample.

Abstract
We administered BCG at microdoses (1 mg) to 34 patients after surgical operation for bladder cancer, from 1981 to 1989. A 9% recurrency rate was observed during a 42 month follow up period. This is not significantly different from that observed with 120 mg doses, which are associated to known complications.
