How does environmental variation translate into biological processes?

2001

Birth and death rates, as so many other biological processes, are usually not linearly related to environmental variation. Common examples of non-linear response forms include unimodal ‘‘optimum-type’’ responses and various saturating responses. These responses filter the signal coming from the environment to a corresponding biological process. We explored how different types of environmental signal may be transformed to a biological process. We were interested in the effect of the filter on modulation of (1) the variance of the signal, on (2) the variance-covariance structure between the signal and the filtered signal, and on (3) the match between the power spectra of the signal and the fi…

Fizioloģisks svara zudums jaundzimušajiem Latvijā: ar to saistītie faktori un atbilstība standartiem

2017

Ievads: veseliem jaundzimušiem pirmajā dzīves nedēļā parasti novēro fizioloģisku svara zudumu (FSZ). Pastāv dažādi viedokļi par FSZ izvērtējumu un to izraisošajiem faktoriem, tādēļ iepriekšējos gados veikti vairāki pētījumi, kuru rezultātā izveidotas svara zuduma diagrammas, kas ataino normālas FSZ svārstības. Latvijā pētījums par FSZ īpatnībām starp Latvijas jaundzimušajiem līdz šim nav veikts. Mērķis: •analizēt FSZ un to ietekmējošus faktorus jaundzimušajiem Latvijā; •izvērtēt iespēju pielietot Amerikas Pediatru asociācijas (APA) FSZ līknes Latvijas jaundzimušajiem. Materiāli un metodes: retrospetīva pētījuma ietvaros tika analizēti dati (dzemdību veids, gestācijas vecums, dzimums, baroša…

MR IMAGING AND HORMONAL FINDINGS IN PATIENTS WITH IDIOPATHIC GROWTH HORMONU DEFICIENCY

1993

Until the introduction of MR imaging in neuroradiological diagnostic, diagnosis of the ecotopic posterior pituitary lobe, first described by the pathologist Priesel in 1920, was rare. Recently it has increasingly been diagnosed by MR in patients whose anamnesis showed birth trauma. We performed MR of the hypothalamic-pituitary region in 17 patients with idiopathic growth hormone deficiency. 8 patients had additional deficiencies of the anterior pituitary lobe whereas the function of the posterior lobe of the hypophysis was normal in all patients. Indications of birth trauma were present in only 2 patients. The cause of anterior lobe insufficiency was determined by MR in 8 patients with panh…

Strategic Actor-Hood and Internal Transformation

2014

In most European countries, the Nordic region included, higher education (HE) has undergone a profound transformation in the last couple of decades. This process is partly a result of substantial changes in society - such as declining birth rates, an ageing population and the rise of a global knowledge-based economy - in tandem with broad policy efforts aimed at modernising the public sector (Peters & Savoie, 1998) as a means of guaranteeing the future sustainability of the (Nordic) welfare state (Christiansen, Petersen, & Haave, 2005).

P72 Lived experiences of midwives and traditional birth attendants caring for pregnant teenagers and teenage mothers: a phenomenological study

2020

Background Teenage mothers are confronted with the double task of passing through the teenage phase and, at the same time, familiarizing themselves with the requirements of motherhood. The characteristics connected with the teenage stage mostly affect the capability of teenage mothers to adapt to the role of being a first-time mother. The essential role of midwives is to provide care for women during pregnancy and motherhood, through coaching, reassurance, supervision and social support. Traditional Birth Attendants (TBAs) are also valued as essential actors in maternal health, providing social support and other antenatal, intrapartum and postnatal care in developing countries. The study ai…

Predictive validity of the GOSLON Yardstick index in patients with unilateral cleft lip and palate: A systematic review

2017

Among the various indices developed for measuring the results of treatment in patients born with unilateral cleft lip and palate (UCLP), the GOSLON Yardstick index is the most widely used to assess the efficacy of treatment and treatment outcomes, which in UCLP cases are closely linked to jaw growth. The aim of this study was to conduct a systematic review to validate the predictability of growth using the GOSLON Yardstick in patients born with UCLP. A systematic literature review was conducted in four Internet databases: Medline, Cochrane Library, Scopus and Embase, complemented by a manual search and a further search in the databases of the leading journals that focus on this topic. An el…

Possible Role of the Posterior Compartment Peritonectomy, as a Part of the Complex Surgery, Regarding Recurrence Rate, Improvement of Symptoms and Fe…

2020

ABSTRACT Study Objective Beside the pain, there are 2 further problems in the management of endometriosis: the high recurrence rate (10% per year) and the high rate of impaired fertility. The objective of this study was to investigate the pathogenesis of these 2 factors. Design This is a retrospective cohort study, and the aim is to evaluate the complete excision of endometriotic lesions, including the posterior compartment of the peritoneum, with regard to postoperative outcome, focusing on relieving pain, increasing fertility rate, and decreasing recurrence rate. Setting Charite-University Clinic, Department of Gynaecology, Endometriosis research Centre. Patients Fifty-four patients were …

Aircraft noise and premature birth

1978

Abstract Certain physiological effects suggest that there may be a relationship between premature birth and noise exposure. Vasoconstriction in the peripheric blood vessel system is one effect. Others would be augmentation of the adrenocorticotrophic hormone and a higher vegetative excitability during pregnancy. Animal experiments have demonstrated negative effects but there is little literature available as yet on the specific relationship between exposure to aircraft noise and negative effects on pregnancies. A study of this relationship was undertaken in an area near the airport at Dusseldorf, Germany. While no significant negative effects could be demonstrated, a tendency toward an incr…

Ramadan During Pregnancy – Fasting, Nutrition, Sleep Patterns and Offspring Health at Birth: A Cross-Sectional Study

2020

Background: Intrauterine exposure to Ramadan is associated with adverse offspring health outcomes. Yet, the dynamics behind these associations remain largely unexplored. We investigate if maternal intermittent fasting or other lifestyle changes during Ramadan affect birth outcomes, and determine whether nutritional and sleep behavior during non-fasting hours influences the fasting-birth weight association. Methods: Linear regressions are estimated using OLS to identify the associations between fasting, sleep behavior, sweets consumption and birth weight, 5-minute APGAR score and gestational age. Interaction terms between fasting and other behaviors are included to explore the potential mode…
