Antarctic Lichens under Long-Term Passive Warming: Species-Specific Photochemical Responses to Desiccation and Heat Shock Treatments.

Climate warming in the Antarctic tundra will affect locally dominant cryptogams. Being adapted to low temperatures and freezing, little is known about the response of the polar lichens' primary photochemistry to warming and desiccation. Since 2008, we have monitored the ecophysiological responses of lichens to the future warming scenario during a long-term warming experiment through open top chambers (OTCs) on Fildes Peninsula.

Peripheral adenopathies in children - an attempt of clinical morphological profile.

Aim: The authors have proposed to assess peripheral adenopathies in a series of hospitalized children in order to identify and define clinical and morphological profiles of different types of lymph node (LN) diseases.

Materials And Methods: The studied group consisted of 58 patients less than 18 years of age. The investigation algorithm included: gender, age, site, involvement, side, extension and histopathological (HP) type of LN lesions.

Inhibition of Primary Photosynthesis in Desiccating Antarctic Lichens Differing in Their Photobionts, Thallus Morphology, and Spectral Properties.

Five macrolichens of different thallus morphology from Antarctica (King George Island) were used for this ecophysiological study. The effect of thallus desiccation on primary photosynthetic processes was examined. We investigated the lichens' responses to the relative water content (RWC) in their thalli during the transition from a wet (RWC of 100%) to a dry state (RWC of 0%).

Characteristics of hypoparathyroidism in Colombia: data from a single center in the city of Medellín.

Objective: Hypoparathyroidism is a rare condition, whose most common etiology is complications of neck surgery. The aim of the study was to identify the clinical and biochemical profile of the patients with diagnosis of hypoparathyroidism, including the frequency of symptoms, clinical signs, long-term complications and disease control. Additionally, the study sought to know what the medication profile was, and the doses required by the patients.

Squamous esophageal carcinoma and mucinous adenocarcinoma of the colon - an unusual association.

The existence of a simultaneous cancer of the esophagus and colon is a rare situation that recognizes an increased incidence in recent years in the world, probably as a result of the improved measures of diagnosis and treatment, as well as the development of screening programs. The aim of this work is to present a case of synchronous esophageal squamous carcinoma with mucinous adenocarcinoma of the hepatic angle of the colon. The patient was hospitalized to our Surgical Clinic with the thoracic squamous esophageal carcinoma diagnosis.

Association between anthropometric indices and cardiometabolic risk factors in pre-school children.

Background: The world health organization (WHO) and the Identification and prevention of dietary- and lifestyle-induced health effects in children and infants- study (IDEFICS), released anthropometric reference values obtained from normal body weight children. This study examined the relationship between WHO [body mass index (BMI) and triceps- and subscapular-skinfolds], and IDEFICS (waist circumference, waist to height ratio and fat mass index) anthropometric indices with cardiometabolic risk factors in pre-school children ranging from normal body weight to obesity.

Methods: A cross-sectional study with 232 children (aged 4.

Neurocognitive subtypes of schizophrenia.

Objective: To empirically identify schizophrenia neurocognitive subtypes and establish their association with clinical characteristics.

Methods: Sustained attention, executive function, facial emotion recognition, verbal learning, and working memory tests were applied to 253 subjects with schizophrenia. We identified neurocognitive subtypes by a latent class analysis of the tests results.

Analysis of aortic size in subjects died due to cardiovascular and non-cardiovascular events: a necropsy study.

Aortic size is known to be a predictor for cardiovascular deaths. The purpose of this study was to investigate whether aortic diameters measured on tissue samples obtained during autopsy from subjects that died of cardiovascular disease were bigger when compared to those from subjects deceased from other cause than cardiovascular disease. The study included 91 deceased subjects (average age 56 ± 18.

Verbal working memory in individuals with schizophrenia and their first degree relatives: relationship with negative and disorganized symptoms.

Objective: To determine whether there are differences in verbal working memory amongst subjects with schizophrenia, their first degree relatives and controls, and to evaluate the influence of symptoms on these differences, as an initial step to assess whether this cognitive function is an endophenotype.

Methods: We examined 197 cases with schizophrenia, 197 first degree relatives and 200 controls through psychiatric interviews and the Letters and Numbers Sequencing test (LNS). Performance was compared among the three groups adjusting for age, sex and education level.

Risk score for pediatric intensive care unit admission in children undergoing hematopoietic stem cell transplantation and analysis of predictive factors for survival.

The authors retrospectively analyzed postransplantation events in 198 children who underwent hematopoietic stem cell transplantation (HSCT) between 1998 and 2002 to obtain a risk score for pediatric intensive care unit (PICU) admission and to ascertain variables predicting a poor outcome. Thirty-six patients (18%) were admitted to the PICU. Median age was 9 years (range 1-18).

Predicting factors for admission to an intensive care unit and clinical outcome in pediatric patients receiving hematopoietic stem cell transplantation.

Background And Objectives: In children, hematopoietic stem cell transplantation (HSCT) implies life-threatening complications and some patients need admission to a pediatric intensive care unit (PICU). Few studies have been reported analyzing this issue in a pediatric population and most focused on risk factors predicting survival following PICU admission.

Design And Methods: We examined data of 240 pediatric patients who received HSCT (100 allogeneic and 140 autologous) in order to ascertain the incidence of life-threatening complications requiring PICU admission, the contributing risk factors and the patients' long-term survival.
