Correlates of online health information-seeking behaviors in a low-income Hispanic community.

OBJECTIVE: The purpose of this study was to explore the correlates of online health information-seeking behaviors among Hispanic residents of a low-income urban neighborhood. METHODS: Data were collected with a community survey from 1045 unique participants at ambulatory care clinics in a largely Hispanic immigrant community in northern Manhattan, New York. A descriptive correlational analysis was conducted using logistic regression. RESULTS: A majority of the participants were born outside the United States (85.7%), and half (50.3%) had completed high school. A logistic regression revealed that five independent variables were significantly correlated with online health information-seeking behaviors: age, education, marital status, primary language, and health literacy. Age and Spanish as preferred language were negatively associated with online health information-seeking (OR = 0.93 and 0.50), whereas education and health literacy were positively associated with online health information-seeking (OR = 4.28 and 1.28). CONCLUSIONS: The findings have implications for designing online health information resources and interventions appropriate for the populations they are likely to reach. Furthermore, the findings highlight the need for special efforts to ensure access to reliable health information for immigrant populations and those with low health literacy.

Abnormally invasive placenta-prevalence, risk factors and antenatal suspicion: results from a large population-based pregnancy cohort study in the Nordic countries.

OBJECTIVE: The objective was to investigate prevalence, estimate risk factors, and antenatal suspicion of abnormally invasive placenta (AIP) associated with laparotomy in women in the Nordic countries. DESIGN: Population-based cohort study. SETTING AND POPULATION: A 3-year Nordic collaboration among obstetricians to identify and report on uterine rupture, peripartum hysterectomy, excessive blood loss, and AIP from 2009 to 2012 The Nordic Obstetric Surveillance Study (NOSS). METHODS: In the NOSS study, clinicians reported AIP cases from maternity wards and the data were validated against National health registries. MAIN OUTCOME MEASURES: Prevalence, risk factors, antenatal suspicion, birth complications, and risk estimations using aggregated national data. RESULTS: A total of 205 cases of AIP in association with laparotomy were identified, representing 3.4 per 10 000 deliveries. The single most important risk factor, which was reported in 49% of all cases of AIP, was placenta praevia. The risk of AIP increased seven-fold after one prior caesarean section (CS) to 56-fold after three or more CS. Prior postpartum haemorrhage was associated with six-fold increased risk of AIP (95% confidence interval 3.7-10.9). Approximately 70% of all cases were not diagnosed antepartum. Of these, 39% had prior CS and 33% had placenta praevia. CONCLUSION: Our findings indicate that a lower CS rate in the population may be the most effective way to lower the incidence of AIP. Focused ultrasound assessment of women at high risk will likely strengthen antenatal suspicion. Prior PPH is a novel risk factor associated with an increased prevalence of AIP. TWEETABLE ABSTRACT: An ultrasound assessment in women with placenta praevia or prior CS may double the awareness for AIP.

Evaluating iodine deficiency in pregnant women and young infants-complex physiology with a risk of misinterpretation.

OBJECTIVE: To review methods for evaluating iodine deficiency in pregnant women and young infants and to discuss factors to be considered in the interpretation of their results. DESIGN: Review of the literature regarding the various methods available for assessing iodine status. SETTING: Population surveys and research studies. SUBJECTS: Pregnant women and young infants. RESULTS: Several factors to consider when assessing iodine status in pregnant women and young infants include: 1) the urinary iodine (UI) concentration (microg l-1) is not interchangeable with 24 h UI excretion (microg per 24 h); 2) the concentration of iodine in a spot or casual urine sample cannot be used to diagnose iodine deficiency in an individual; 3) a moderate fall in the concentration of serum free T4 during pregnancy is not a sign of maternal iodine deficiency; 4) an increase in the concentration of serum thyroglobulin (Tg) during pregnancy is not a sign of maternal iodine deficiency; 5) a higher concentration of TSH and Tg in cord blood than in maternal blood is not a sign of iodine deficiency in the mother or neonate; and 6) thyroid function in a full-term foetus, a neonate or a small child is not more sensitive to a mild iodine deficiency than in the mother. CONCLUSIONS: If the iodine status of pregnant women and small children is not to be misjudged, the above six factors need to be taken into account.

The contraceptive vaginal ring (NuvaRing) and hemostasis: a comparative study.

This open-label, nonrandomized study compared changes in hemostatic variables during NuvaRing and oral levonorgestrel 150 microg/ethinylestradiol 30 microg (LNG/EE) use for six cycles. Eighty-seven women started the study, 44 with NuvaRing and 43 with the LNG/EE oral contraceptive. For most procoagulation variables, there was no difference between NuvaRing and oral LNG/EE; only Factor VII levels increased in the NuvaRing group and decreased in the LNG/EE group. The majority of assessed variables show that anticoagulation and fibrinolytic activity was comparable between the NuvaRing and oral LNG/EE groups. Antithrombin activity and protein C activity both tended to be higher with NuvaRing. Levels of tissue plasminogen activator decreased in both groups but the reduction was smaller with NuvaRing. There were no significant differences in fibrin turnover between the treatment groups. The data show that both NuvaRing and oral LNG/EE are associated with a minimal effect on hemostatic variables.

Comparative study of the effects of a progestogen-only pill containing desogestrel and an intrauterine contraceptive device in lactating women.

OBJECTIVE: To evaluate the effects of desogestrel 75 microg/day, as a progestogen-only pill compared with a copper-bearing intrauterine contraceptive device (IUCD) on lactation and to study the safety of both treatments in mothers and children. Transfer of etonogestrel to breast milk was studied in a subgroup of desogestrel users. The children were to be followed up until 2.5 years of age. DESIGN: An open, non-randomised, group-comparative study in lactating women. SETTING: University Hospital, Reykjavik, Iceland. PARTICIPANTS: A total of 83 lactating women; 42 received desogestrel and 41 had an IUCD inserted for seven consecutive treatment cycles of 28 days. METHODS: Evaluation visits were planned at baseline and at the end of treatment cycles 1, 4 and 7. The amount of breast milk was determined by weighing the infants before and after feeding, at baseline and after treatment cycles I and 4. Milk samples were obtained at the same time for constituent measurements. Safety was studied by structured medical examinations and by recording adverse experiences in mothers and children. RESULTS: There were no significant differences between the desogestrel and IUCD groups in composition and quantity of breast milk nor in growth and development of the children followed up to the age of 2.5 years. In the desogestrel group a slightly higher incidence of mild adverse experiences of a hormonal nature was reported among both mothers and infants. Of the children 82% were followed until 1.5 years of age and 50% until 2.5 years. CONCLUSION: The use of desogestrel 75 microg/day did not change the amount and composition of breast milk nor did it affect growth and development of the breastfed children. It appears to be a safe and effective contraceptive method for lactating women

A genome-wide scan reveals a maternal susceptibility locus for pre-eclampsia on chromosome 2p13.

Pre-eclampsia is a common and serious disease and a major cause of maternal and infant mortality. Antenatal care systems world-wide screen for signs of the disease such as hypertension and proteinuria. Unlike most other human disorders it impacts two individuals, the mother and the child, both of whom can be severely affected. The pathophysiology of the disorder is incompletely understood, but familial clustering of the disease is apparent. Here we report the results of a genome-wide screen of Icelandic families representing 343 affected women. Including those patients with non-proteinuric pre-eclampsia (gestational hypertension), proteinuric pre-eclampsia and eclampsia, we detected a significant locus on 2p13 with a lod score of 4.70 (single point P < 3.49 x 10(-6)). This is the first reported locus for pre-eclampsia meeting the criteria for genome-wide significance.

[Perinatal death classification in Iceland 1994-1998.].

OBJECTIVE: To analyse perinatal deaths in Iceland (>22 weeks or 500 g) over a five year period by a new Nordic classification. MATERIAL AND METHODS: Medical records for all cases of perinatal death in Iceland from 1994-1998 were analysed. A classification focussing on potential avoidability from a health service perspective was used to identify major groups and areas for improvement. The classification is based on the following variables: time of death in relation to admission and delivery, fetal malformation, gestational age, growth-retardation and Apgar score at five minutes. RESULTS: One hundred and fifty-eight perinatal deaths occurrecl. Of these 103 (65%) were stillborn babies and 55 were early neonatal deaths. The cumulative perinatal mortality rate (PNMR) was 7.3/1000 births for the period and all perinatal deaths, but using a cut-off point >28 weeks or 1000 g this was lower, 5.1/1000. Potentially avoidable groups accounted for 12% of the perinatal deaths, i.e. growthretarded singletons after >28 weeks and intrapartum deaths after >28 weeks. Almost half of the perinatal deaths (41.1%) could probably not be prevented with present methods in perinatal care. These included intrauterine deaths of non-growth retarded singletons after 28 weeks (27.8%) and intrauterine deaths be-fore 28 weeks, still considered miscarriages in some countries (13.3%). Two-thirds of the early neonatal. CONCLUSIONS: The Nordic classification used gave a good picture of the causes of avoidable and unavoidable perinatal deaths and may facilitate comparison between populations and periods.

Evidence for a familial pregnancy-induced hypertension locus in the eNOS-gene region.

Pregnancy-induced hypertension may be regarded as a manifestation of endothelial-cell dysfunction. The role of the eNOS gene in the development of a familial pregnancy-induced hypertension was evaluated by analysis of linkage among affected sisters and in multiplex families (n = 50). Markers from a 4-cM region encoding the eNOS gene showed distortion from the expected allele sharing among affected sisters (P = .001-.05), and the statistic obtained from the multilocus application of the affected-pedigree-member method also showed distortion (T[f(P)=sqrt(P)] = 3.53; P < .001). A LOD score of 3.36 was obtained for D7S505 when a best-fitting model derived from genetic epidemiological data was used, and LOD scores of 2.54-4.03 were obtained when various other genetic models were used. Estimates of recombination rate, rather than maximum LOD-score values, were affected by changes in the genetic parameters. The transmission-disequilibrium test, a model-free estimate of linkage, showed strongest association and linkage with a microsatellite within intron 13 of the eNOS gene (P = .005). These results support the localization of a familial pregnancy-induced hypertension-susceptibility locus in the region of chromosome 7q36 encoding the eNOS gene.

[Laparoscopic cholecystectomies. First 100 attempted cases at Reykjavik City Hospital].

An account is given of the first 100 attempted laparoscopic cholecystectomies at Borgarspitalinn, Reykjavik City Hospital. The mean age of the patients was 48.7 years with a range of 17-86 years. Seventy seven of the patients were women and 23 men. Ten patients (10%) had acute cholecystitis but others had uncomplicated cholelithiasis. In 10 patients the operation was converted to conventional open cholecystectomy, in most cases because of acute inflammation or adhesions from previous surgery but in one case because of haemorrhage. Five patients had complications, all of which can be considered minor. There was no common bile duct injury and no mortality. No patient required reoperation. The mean operative time for the laparoscopic cholecystectomies was 102 minutes (range 50-222 minutes) and 75% of the operations were completed within two hours. The mean operative time for the first 30 laparoscopic cholecystectomies was 109.7 minutes and dropped to 94.3 minutes for the last 30. The operative time has continued to decrease with further experience. Fifty four percent of the patients who underwent laparoscopic cholecystectomies were discharged from hospital on the first postoperative day and a further 32% on the 2nd day after surgery. The hospital stay was on average four days shorter than after the conventional open cholecystectomies performed in the last months prior to commencing laparoscopic surgery. Eighty three percent of the patients were back to work or previous activity within two weeks of surgery compared to only 11.4% of patients who had undergone open cholecystectomies. Laparoscopic cholecystectomy is felt to be a safe procedure and highly cost-effective.
