Preeclampsia is a complication of pregnancy characterized by inadequate placentation,resultant ischemia and failure of several maternal organs. Preeclampsia is one of the mostserious conditions in pregnancy and a leading cause of maternal and perinatal morbidity andmortality. Various risk factors and some protective factors have been reported associated topreeclampsia. Finally, women who develop preeclampsia during pregnancy are at higher riskof future diabetes mellitus, hypertension and cardiovascular complications. In this article anupdate on the epidemiology of preeclampsia is presented.Keywords: Preeclampsia, prevalence, risk factors, protective factors, complications, maternalmortality, perinatal mortality.

Purpose – This paper aims to examine the short-term effect of the Arizona Immigration Law of 2010 (SB1070) on the noncitizen Hispanic state population. Design/methodology/approach – To get a consistent estimate of this effect a synthetic control method has been used to calculate a suitable counterfactual. Findings – Results indicate that this bill produced a statistically significant short-term reduction in the proportion of noncitizen Hispanics in Arizona between 10 and 15 per cent. However the evidence suggests that this effect vanishes after a few months. Originality/value – These findings are consistent with previous evidence of the high mobility of the undocumented population in the US and contribute to the understanding of the effects of federal and statelevel immigration legislation.

Background: Physiological changes during pregnancy are often accompanied by reduced sleep quality, sleep disruptions, and insomnia. Studies conducted among men and non-pregnant women have documented psychiatric disorders as common comorbidities of insomnia and other sleep disorders. However, no previous study has examined the association between stress-related sleep disturbances and psychiatric disorders among pregnant women. Methods: This cross-sectional study included a total of 2051 pregnant women in Peru. The Spanish-language version of the Ford Insomnia Response to Stress Test (FIRST-S) was used to assess sleep disruptions due to stressful situations. Symptoms of antepartum depression, generalized anxiety disorder, and posttraumatic stress disorder (PTSD) were examined using the Patient Health Questionnaire-9, Generalized Anxiety Disorder Scale-7 and PTSD Checklist – Civilian Vers...

Objectives To examine the associations of Intimate partner violence (IPV) with stress-related sleep disturbance (measured using the Ford Insomnia Response to Stress Test [FIRST]) and poor sleep quality (measured using the Pittsburgh Sleep Quality Index [PSQI]) during early pregnancy. Methods This cross-sectional study included 634 pregnant Peruvian women. In-person interviews were conducted in early pregnancy to collect information regarding IPV history, and sleep traits. Adjusted odds ratios (aOR) and 95% confidence intervals (95%CIs) were calculated using logistic regression procedures. Results Lifetime IPV was associated with a 1.54-fold increased odds of stress-related sleep disturbance (95% CI: 1.08–2.17) and a 1.93-fold increased odds of poor sleep quality (95% CI: 1.33–2.81). Compared with women experiencing no IPV during lifetime, the aOR (95% CI) for stress-related sleep dis...

Background Preterm birth is a leading cause of perinatal morbidity and mortality worldwide, resulting in a pressing need to identify risk factors leading to effective interventions. Limited evidence suggests potential relationships between maternal sleep or vital exhaustion and preterm birth, yet the literature is generally inconclusive. Methods We examined the relationship between maternal sleep duration and vital exhaustion in the first six months of pregnancy and spontaneous (non-medically indicated) preterm birth among 479 Peruvian women who delivered a preterm singleton infant (<37 weeks gestation) and 480 term controls who delivered a singleton infant at term (≥37 weeks gestation). Maternal nightly sleep and reports of vital exhaustion were ascertained through in-person interviews. Spontaneous preterm birth cases were further categorized as those following either spontaneous pret...

Background Migraine, a common chronic-intermittent disorder of idiopathic origin characterized by severe debilitating headaches and autonomic nervous system dysfunction, and placental abruption, the premature separation of the placenta, share many common pathophysiological characteristics. Moreover, endothelial dysfunction, platelet activation, hypercoagulation, and inflammation are common to both disorders. We assessed risk of placental abruption in relation to maternal history of migraine before and during pregnancy in Peruvian women. Methods Cases were 375 women with pregnancies complicated by placental abruption, and controls were 368 women without an abruption. During in-person interviews conducted following delivery, women were asked if they had physician-diagnosed migraine, and they were asked questions that allowed headaches and migraine to be classified according to criteria est...

Intimate partner violence (IPV) is increasingly recognized as an important cause of maternal and perinatal morbidity. We assessed the relation between IPV and risk of spontaneous preterm birth (PTB) among Peruvian women. The study was conducted among 479 pregnant women who delivered a preterm singleton infant (<37 weeks gestation) and 480 controls (≥37 weeks gestation). Participants’ exposure to physical and emotional violence during pregnancy was collected during in-person interviews conducted after delivery and while patients were in hospital. Odds ratios (aOR) and 95 % confidence intervals (CI) were estimated from logistic regression models. The prevalence of any IPV during pregnancy was 52.2 % among cases and 34.6 % among controls. Compared with those reporting no exposure to IPV during pregnancy, women reporting any exposure had a 2.1-fold increased risk of PTB (95 % CI 1.59–2...

Recent excavations at Huaca Naranjal have registered the recurrence of large pottery sherd contexts, which have been recognized as a waste of pottery production. The analysis of the contexts indicates that the ceramics produced is part of restricted types of Ychsma style result of a pattern of specialize production, that enables the discussion of the socio-economic organization of the population. The recognition of an Ychsma style production pottery center in the lower valley of Chillon poses the problem on its political identification, considering its proximity to the ethnohistoric defined Colli.

The objective of this research is to demonstrate that the heuristic method increases the level of learning of a group of students from I.E.3003-R´ımac in the competences of the area of mathematics. In its implementation, teachers play the role of mediator and strategist following the didactic processes: understanding of the problem, design and execution of the strategy, reflection, formalization of the concepts and transfer. The proper application of the heuristic method promotes the development of intuitive, logical, critical and creative thinking in students. The applied methodology consisted of working with two groups: 6th B students, who were called the experimental group and the heuristic method was applied, and 6th A students, called the control group (x), with whom the traditional method. The procedure consisted of administering an entry test to both groups before the interventi...

Snakebite envenoming is a global neglected disease with an incidence of up to 2.7 million new cases every year. Although antivenoms are so-far the most effective treatment to reverse the acute systemic effects induced by snakebite envenoming, they have a limited therapeutic potential, being unable to completely neutralize the local venom effects. Local damage, such as dermonecrosis and myonecrosis, can lead to permanent sequelae with physical, social, and psychological implications. The strong inflammatory process induced by snake venoms is associated with poor tissue regeneration, in particular the lack of or reduced skeletal muscle regeneration. Mesenchymal stromal cells (MSCs)-based therapies have shown both anti-inflammatory and pro-regenerative properties. We postulate that using allogeneic MSCs or their cell-free products can induce skeletal muscle regeneration in snakebite victims...

Primary aldosteronism is the most common form of secondary hypertension and is present in 5-24% of patients with hypertension and is associated with a significant increase in cardiovascular, cerebrovascular and renal morbidity compared to primary hypertension. Diagnosis depends on the demonstration of an increase in the autonomous secretion of aldosterone in the presence of high salt intake and non-responsive to the renin-angiotensin system. The most common forms of primary aldosterone are an aldosterone-producing adenoma and bilateral idiopathic aldosteronism and less common are unilateral hyperplasia and aldosterone-producing carcinoma. The differential diagnosis is done using a CTscan and especially adrenal vein sampling. The treatment for an aldosterone-producing adenoma is laparoscopic surgery and medical treatment in bilateral aldosteronism with mineralocorticoid receptor antagonis...

The study aimed to analyze the worldviews of three cultures from Abya Yala: the Aymara, Mapuche, and Mayan. These worldviews have survived to the present day and demonstrate alternative ways of relating to nature, which constitute a logic distinct from mercantilist and anthropocentric visions. It also seeks to review the logic behind modernity and contrast it with the worldviews of nature of the three cultures mentioned. The methodology employed is a qualitative, documentary approach. According to the dynamics of progress and development inherent to capitalism, nature has been conceived as a source of resources whose exploitation is justified by economic growth. In this context, human beings appear as superior entities alienated from the natural world. This is different from the perspectives present in the knowledge of some indigenous peoples. The findings revealed that the documented cu...
