The effect of a digital intervention on symptoms of depression in pregnant women exposed to Intimate partner violence in Denmark and Spain (STOP study).

INTRODUCTION AND OBJECTIVE: Intimate Partner Violence (IPV) during pregnancy is a significant public health concern associated with adverse maternal and fetal health outcomes, including increased risk of depression. This study aimed to assess the effectiveness of a digital empowerment-based intervention in reducing symptoms of depression among IPV-exposed pregnant women. STUDY DESIGN: This intervention study was nested within a cohort study conducted in Denmark and Spain. Pregnant women attending antenatal care were digital screened for IPV using the Abuse Assessment Screen (AAS) and the Women's Abuse Screening Tool (WAST). Those screening positive were offered a digital intervention comprising 3-6 video consultations with trained IPV counsellors and access to a safety planning app. Changes in depression scores from baseline to follow-up were evaluated using mixed model regression. RESULTS: From February 2021-October 2022, 1,545 pregnant women (9.6 %) screened positive for IPV within our population (8.5 % in Denmark and 17.0 % in Spain) with 485 (31.4 %) meeting the criteria for the intervention. Of those eligible, 104 (21.4 %) accepted the intervention, and 55 completed it (13.1 %). Post-intervention, a significant reduction in Edinburgh Postnatal Depression Scale (EPDS) was found, with a mean difference of -3.9 (95 % CI: -5.3; -2.4), compared to the average pre-intervention score of 11.3. Stratifying the analyses across sociodemographic variables did not alter the overall result, indicating a reduction in EPDS scores irrespective of setting or sociodemographic factors. Notably, the intervention was most effective for women initially presenting with EPDS scores above the depression cut-off. CONCLUSION: The findings suggest that a brief digital intervention is associated with a reduction in depression symptoms among pregnant women exposed to IPV, particularly among those with high depressive scores. This highlights the potential of digital interventions in delivering counseling and shows efficacy when administered by both midwives and psychologists in diverse settings. However, the absence of a control group underscores the need for caution in interpreting the results.

Neonatal phototherapy and risk of epilepsy-A Danish population based study.

To evaluate the risk of epilepsy in children who received neonatal phototherapy. A cohort of live singletons born at a Danish hospital (2002-2016) with a gestational age ≥ 35 weeks. We used Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of epilepsy in children treated with neonatal phototherapy compared to children not treated with neonatal phototherapy in the general population, and in a subpopulation of children who had serum bilirubin measurement. Adjusted HRs (aHR) were computed using multivariable and propensity score matching models to take maternal and neonatal factors into consideration. Children were followed from day 29 after birth to diagnosis of epilepsy, death, emigration, or December 31, 2016. Among 65,365 children, 958 (1.5%) received neonatal phototherapy. Seven children (incidence rates (IRs): 10.8 /10,000 person-years) who received neonatal phototherapy and 354 children (IR: 7.7) who did not receive neonatal phototherapy were diagnosed with epilepsy. Neonatal phototherapy was not associated with an increased risk of epilepsy using the multivariable (aHR 0.95, 95% CI: 0.43-2.09) and propensity score matched (aHR 0.94, 95% CI: 0.39-2.28) models. In the subpopulation of 9,378 children with bilirubin measurement, 928 (9.9%) received neonatal phototherapy. In the analysis of the subpopulation in which bilirubin level and age at the time of bilirubin measurement were further taking into consideration, neonatal phototherapy was not associated with an increased risk of epilepsy using the multivariable (aHR 1.26, 95% CI: 0.54-2.97) and propensity score matched (aHR 1.24, 95% CI: 0.47-3.25) models,Conclusions: Neonatal phototherapy was not associated with an increased risk of epilepsy after taking maternal and neonatal factors into consideration. What is known: • A few studies have suggested that neonatal phototherapy for hyperbilirubinemia may increase the risk of childhood epilepsy. • Whether the observed associations contribute to hyperbilirubinemia, phototherapy, or underlying factors requires further investigation. What is new: • This study revealed no increased risk of epilepsy in children treated with neonatal phototherapy compared to children not treated with phototherapy after taking maternal and neonatal factors into consideration. • After further taking bilirubin level and age at the time of bilirubin measurement into consideration, neonatal phototherapy was not associated with an increased risk of epilepsy.

Existential communication in maternity care - Mixed method evaluation of a postgraduate short course.

OBJECTIVE: The birth of a child is a significant life event, possibly accompanied by thoughts and feelings of existential turmoil, which some parents need to share. Maternity care professionals may be unprepared for this, as very few educational initiatives exist with a focus on existential communication. We evaluated the curriculum and delivery of a course in existential communication for midwives. The evaluation was based on participants' experiences of self-reported self-efficacy and self-reflection before and after participation. METHODS: A parallel mixed methods design with pre- and post-course questionnaires and field observations. Quantitative data were evaluated using Mann-Whitney analyses, and open-ended questions and field observations were thematised for further analysis. RESULTS: Seventy-three maternity care professionals participated in the course. Of these, 69 (95%) completed a pre-course questionnaire, and 71 (97%) a post-course questionnaire. The quantitative data found a significant difference in various participant measures such as increase in self-efficacy in existential communication and understanding of existential communication. Qualitative data from the questionnaires and field observations led to six different themes including topics such as the need for reflection with peers and the presence of existential within maternity care. CONCLUSIONS: The course evaluation suggested an increase in participants' awareness of existential aspects of maternity care and improved self-reflection and existential awareness.

Effect of superheated steam treatment on enzyme inactivation, morphostructural, physicochemical and digestion properties of sand rice (Agriophyllum squarrosum) flour.

The lipase (LA) and peroxidase (POD) activities, as well as morphological structure, physicochemical and digestion properties of sand rice flour (SRF) treated with superheated steam (SS), were investigated. SS treatment at 165 °C completely deactivated LA and resulted in a 98% deactivation of POD activities in SRF. This treatment also intensified gelatinization, induced noticeable color alterations, and decreased pasting viscosities. Furthermore, there was a moderate reduction in crystal structure, lamellar structure, and short-range ordered structure, with a pronounced reduction at temperatures exceeding 170 °C. These alterations significantly impacted SRF digestibility, leading to increased levels of rapidly digestible starch (RDS) and resistant starch (RS), with the highest RS content achieved at 165 °C. The effectiveness of SS treatment depends on temperature, with 165 °C being able to stabilize SRF with moderate changes in color and structure. These findings will provide a scientific foundation for SS applicated in SRF stabilization and modification.

Effect of endogenous protein and lipid removal on the physicochemical and digestion properties of sand rice (Agriophyllum squarrosum) flour.

The study investigated the effect of removing protein and/or lipid on the physicochemical characteristics and digestibility of sand rice flour (SRF). Morphological images showed that protein removal had a greater impact on exposing starch granules, while lipids acted as an adhesive. The treatment altered starch content in SRF samples, leading to increased starch crystallinity, denser semi-crystalline region, lower onset gelatinization temperature (To), higher peak viscosity and gelatinization enthalpy (ΔH), where Protein removal showed a more pronounced effect on altering physicochemical properties compared to lipid removal. The research revealed a positive correlation between rapidly digestible starch (RDS), maximum degree of starch hydrolysis (C∞), digestion rate constant (k) values and 1047/1022 cm-1 ratio, showing a strong connection between short-range structure and starch digestibility. The presence of endogenous proteins and lipids in SRF hinder digestion by restricting starch swelling and gelatinization, and physically obstructing enzyme-starch interaction. Lipids had a greater impact on starch digestibility than proteins, possibly due to their higher efficacy in reducing digestibility, higher lipid content with greater potential to form starch-lipid complexes. This study provides valuable insights into the interaction between starch and proteins/lipids in the sand rice seed matrix, enhancing its applicability in functional and nutritional food products.

Parity, mode of birth, and long-term gynecological health: A follow-up study of parous and nonparous women in the Australian Longitudinal Study on Women's Health cohort.

BACKGROUND: Although gynecological health issues are common and cause considerable distress, little is known about their causes. We examined how birth history is associated with urinary incontinence (UI), severe period pain, heavy periods, and endometriosis. METHODS: We studied 7700 women in the Australian Longitudinal Study on Women's Health with an average follow-up of 10.9 years after their last birth. Surveys every third year provided information about birth history and gynecological health. Logistic regression was used to estimate how parity, mode of birth, and vaginal tears were associated with gynecological health issues. Presented results are adjusted odds ratios (OR) with 95% confidence intervals. RESULTS: UI was reported by 16%, heavy periods by 31%, severe period pain by 28%, and endometriosis by 4%. Compared with women with two children, nonparous women had less UI (OR 0.35 [0.26-0.47]) but tended to have more endometriosis (OR 1.70 [0.97-2.96]). Also, women with only one child had less UI (OR 0.77 [0.61-0.98]), but more severe period pain (OR 1.24 [1.01-1.51]). Women with 4+ children had more heavy periods (OR 1.42 [1.07-1.88]). Compared with women with vaginal birth(s) only, women with only cesarean sections or vaginal birth after cesarean section had less UI (ORs 0.44 [0.34-0.58] and 0.55 [0.40-0.76]), but more endometriosis (ORs 1.91 [1.16-3.16] and 2.31 [1.25-4.28]) and heavy periods (ORs 1.21 [1.00-1.46] and 1.35 [1.06-1.72]). Vaginal tear(s) did not increase UI after accounting for parity and birth mode. CONCLUSION: While women with vaginal childbirth(s) reported more urinary incontinence, they had less menstrual complaints and endometriosis.

Adherence to support pessary in the treatment of pelvic organ prolapse: a retrospective study conducted among 1,371 women.

INTRODUCTION AND HYPOTHESIS: The objective was to investigate the adherence to pessary treatment in women with pelvic organ prolapse (POP) who were found eligible for this treatment by the urogynecologist, at the first visit at the Department of Gynecology and Obstetrics, Odense University Hospital. METHODS: Data were extracted from the women's medical records. Frequency tabulations were performed to describe the women's reasons for pessary discontinuation by age group. Binominal logistic regression analysis was conducted to investigate how women's age, POP characteristics, urogynecological history, and their pessary experience and management were associated with continued pessary use. RESULTS: This study included 1,371 women treated with support pessary. Of these, 850 women continued pessary treatment and 521 women underwent surgical treatment. A history of hysterectomy (OR: 0.68, 95% CI: 0.51-0.90, p = 0.008), urinary incontinence (OR: 0.71, 95% CI: 0.56-0.89, p = 0.003), and previous pessary use (OR: 0.75, 95% CI: 0.56-0.99, p = 0.047) were significant factors associated with discontinuation. Further, women aged 81-99 years were significantly more likely to continue pessary treatment (OR: 1.77, 95% CI: 1.15-2.74, p = 0.009). "POP surgery," "prolapse stage," and "prolapse predominant compartment" were not associated with discontinuation. Approximately 38% of women aged 26-54 years discontinued owing to personal preference. CONCLUSIONS: Hysterectomy, incontinence, and previous pessary use are significant predictors of pessary discontinuation. Increasing age is significantly associated with pessary continuation.

Fractures in Childhood and Young Adulthood According to Maternal Smoking in Late Pregnancy. A Danish Cohort Study.

BACKGROUND: Fractures account for the most frequent cause of hospitalization during childhood and numbers have increased over time. Of all fractures in childhood and young adulthood, 66% are recurrent fractures, suggesting that some people are predestined for fractures. The aim of this study was to investigate the association between maternal smoking during late pregnancy and the risk of fractures in the children. METHODS: The study included 11,082 mothers and their children from the cohort "Healthy Habits for Two" born between 1984 and 1987. Information about maternal smoking during pregnancy came from questionnaires filled out in pregnancy, while information about fractures was derived from the Danish National Patient Registry. Over a follow-up of 24 years (1994-2018), Cox regression with multiple failures was used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) for fractures in childhood and young adulthood according to maternal smoking in late pregnancy. Information about body mass index (BMI) and smoking status in young adulthood was included as time variant covariates. RESULTS: During an age span of 8-32 years, 6,420 fractures were observed. Of the mothers, 39.1% smoked during late pregnancy. Compared to children of mothers who did not smoke, children of mothers who smoked 1-9 cigarettes per day and 10+ cigarettes per day had an increased risk of fractures (HR 1.14 [CI: 1.06; 1.21] and HR 1.14 [CI: 1.07; 1.22], respectively). After adjusting for BMI and smoking status in young adulthood, the findings were slightly strengthened, showing an increased risk of fractures of 23 and 25% in children of mothers smoking 1-9 cigarettes per day and 10+ cigarettes per day, respectively. CONCLUSION: Maternal smoking during late pregnancy was associated with a higher risk of fractures in the child. This result indicates that exposure to cigarette smoke in utero may play a role in lifelong bone health.

Patient-initiated follow-up in women with early-stage endometrial cancer: A long-term follow-up of the OPAL trial.

OBJECTIVE: A long-term follow-up of the OPAL trial to compare the effect of patient-initiated (PIFU) versus hospital-based (HBFU) follow-up on fear of cancer recurrence (FCR), quality of life (QoL) and healthcare use after 34 months of follow-up. DESIGN: Pragmatic, multicentre randomised trial. SETTING: Four Danish departments of gynaecology between May 2013 and May 2016. POPULATION: 212 women diagnosed with stage I low-intermediate risk endometrial carcinoma. METHODS: The control group attended HBFU with regular outpatient visits (i.e., 8) for 3 years after primary treatment. The intervention group underwent PIFU with no prescheduled visits but with instructions about alarm symptoms and options of self-referral. MAIN OUTCOME MEASURES: The endpoints were FCR as measured by the Fear of Cancer Recurrence Inventory (FCRI) and QoL as measured by the European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire C-30 (EORTC QLQ C-30), and healthcare use as measured by questionnaires and chart reviews after 34 months of follow-up. RESULTS: FCR decreased from baseline to 34 months in both groups and no difference was found between allocations (difference -6.31 [95% confidence interval -14.24 to 1.63]). QoL remained stable with no difference in any domains between the two arms at 34 months using a linear mixed model analysis. The use of healthcare was significantly lower in the PIFU group (P < 0.01). CONCLUSION: Patient-initiated follow-up is a valid alternative to hospital-based follow-up for people who have been treated for endometrial cancer and have low risk of recurrence.

Effect of rice protein on the gelatinization and retrogradation properties of rice starch.

In this study, rice starch (RS) was mixed with varying amounts of rice protein (RP; 0 % to 16 %) to explore the effects of protein on the gelatinization and retrogradation of starch during storage. The increased RP addition decreased the viscosity and gelatinization enthalpy of the mixtures but caused an upward trend in the gelatinization temperature, indicating that protein hampers the process of starch gelatinization. Furthermore, RP addition reduced gel hardness, decreased retrogradation enthalpy and crystallization rate constant, but increased Avrami exponent upon RS retrogradation. RP addition also facilitated the mobility of water molecules, weakened the conversion from bound water to free water in the gels, and moderately increased the uniformity and thickness of gel shape. In summary, RP had a dose-dependent effect on the gelatinization and retrogradation behavior of RS, although the anti-retrogradation concentration effect strongly weakened at protein levels exceeding 12 %. It is noteworthy, that excessive RP addition resulted in disulfide bond formation, which increased gel strength and network structure but reduced the ability of RP to facilitate water molecule mobility and restrict water migration, ultimately reducing its anti-retrogradation capability. This phenomenon can be partially attributed to spontaneous protein-protein interaction caused by excessive protein addition, replacing the starch-protein interaction.

Occlusive wound closure prevents prolonged wound discharge-A randomised controlled trial in patients undergoing tumour resection and endoprosthetic reconstruction of the proximal femur because of metastatic bone disease.

Prolonged wound discharge is a common postoperative complication of orthopaedic procedures and a risk factor for implant-related infection. Occlusive wound closure methods have previously been suggested to reduce or even prevent this complication. We performed a randomised controlled trial on 70 patients who underwent surgical treatment for metastatic bone disease involving the proximal femur at our centre between January 2017 and August 2018. At conclusion of the tumour resection and endoprosthetic reconstruction procedure, patients were randomised to either occlusive wound closure (n = 35), using the Dermabond Prineo-22 skin closure system, or routine wound closure with conventional skin staples (n = 35). Skin closure with occlusive wound closure resulted in a lesser degree (P < .0001) and shorter duration of postoperative wound discharge (HR 2.89 [95% CI 1.6-5.05], P < .0018). Compared with staples, surgical wounds were already dry after a mean of 3.5 days [95% CI 3.2-3.9] versus 6.1 days [95% CI 4.8-7.3] (P < .0001). Prolonged wound discharge for 7 days or more was observed in 23% of patients (n = 8) in the Staples-group but was entirely absent in the occlusive wound closure group (P < .003). This study provides strong evidence that occlusive wound closure reduces frequency, degree, and duration of wound discharge in a patient population at particularly high risk for this complication.

Neonatal Phototherapy and Clinical Characteristics: The Danish National Patient Registry 2000-2016.

Purpose: Phototherapy is the standard treatment for neonatal hyperbilirubinemia. It is important to collect data on phototherapy to support research related to the efficacy and safety of phototherapy. We explored the registration of phototherapy in the Danish National Patient Registry (DNPR) and the clinical characteristics of neonates treated with phototherapy. Methods: We identified children born alive in Denmark from 1 January 2000 through 30 November 2016 from the DNPR (N=1,044,502). We calculated the proportion of children registered that received phototherapy during the neonatal period and examined temporal trends, both nationwide and at the level of individual hospitals. In a sub-cohort of children born at Aarhus University Hospital (AUH) in 2002-2016 (N=71,781), we analyzed the proportions of children registered that received phototherapy, according to sex, gestational age, birth weight, and neonatal characteristics, like Apgar score, birth asphyxia, and infections. Results: We identified 11,295 (1.1%) registered that received phototherapy. The proportions of children registered that received phototherapy differed among hospitals (range: 0 to 4.1%). Nationwide registration was low during the study period, but it increased to 1.8% in 2016. For the AUH sub-cohort the proportion of children registered with phototherapy averaged 4.4% (N=3182, range:3.9-5.1%). The proportion of children registered with phototherapy was inversely correlated with gestational age and birth weight, and positively correlated with neonatal characteristics, including low Apgar score, birth asphyxia, and infections. Conclusion: Phototherapy was under-reported in the DNPR and the proportions of children registered that received phototherapy differed among hospitals. The non-compulsory policy for reporting treatment and care in hospitals to the DNPR might explain the variation. The most consistent reporting was observed among children born in an university hospital, where 4.4% of children registered that received phototherapy, and phototherapy was inversely associated with gestational age, birth weight, and positively associated with clinical characteristics like birth asphyxia, and infections.

Dietary exposure to acrylamide of university students in Ningxia of Northwest China and the effect on their neurobehavioral performance and oxidative stress in serum.

This study aims to investigate dietary exposure to acrylamide (AA) and also make an assessment of its effect on the neurobehavioral performance and oxidative stress in the serum of university students in Ningxia. The place primarily consists of arid, dry desert, and wheat-based foods are the staple food there. A total of 803 university students in Ningxia participated in this cross-sectional study. Diet intake of AA was estimated with FFQ. The AA risk was calculated as margin of exposure (MOE) values. NCTB questionnaires were used to assess neurobehavioral performance. The serum oxidative stress levels of the university students were measured as GSH, MDA, and SOD. The mean for AA exposure of university students was 0.515 µg kg-1 bw day-1. The highest contributor was traditional Chinese grain products, representing 34.71% of the total daily AA intake. Followed were deep-fried potato products, traditional Western grain products, soft drinks, and nuts, which accounted for 23.87%, 16.59%, 11.15%, and 11%, respectively. The median AA exposure were 480 (BMDL10 = 0.18 mg kg-1 bw day-1) and 827 (BMDL10 = 0.31 mg kg-1 bw day-1), respectively. The results indicated that diet AA may have an effect on the emotional status and neurobehavior among this population. We observed no significant differences in oxidative stress under the three levels of AA exposure (p > .05). It suggests a health concern for university students in Northwest China that should get society's attention.

Parental information about the option to apply for pregnancy termination after the detection of a congenital abnormality and factors influencing parental decision-making: a cohort study.

BACKGROUND: The detection of an abnormality during prenatal screening implies that the parents are informed about possible treatment and management of the pregnancy, birth, and postnatal course. This information should enable the parents to make decisions regarding the pregnancy, especially in cases where termination of pregnancy may be an option. The objectives of this study were to investigate how often doctors informed parents about pregnancy termination when the fetus had an anomaly and which demographic factors were related to parental decision-making. METHODS: This was a retrospective cohort study with prospectively collected data of fetuses diagnosed with an abnormality during prenatal screening between 2014 and 2016 in Denmark. We categorized the abnormalities into five long-term prognosis groups and analyzed their association with the doctor provided information about termination. We tested the association between demographic variables and parental decisions using univariate and multivariate statistical analyses. RESULTS: Three hundred and twenty fetuses were diagnosed with an abnormality. In 67% of these cases, the parents were informed about termination. All parents whose fetus had a lethal prognosis were informed about termination. By comparison, the parents of 98% of fetuses with genetic disorders, 96% of fetuses with poor prognosis, 69% of fetuses with uncertain prognosis, and 12% of fetuses with good prognosis were informed about termination. Of these parents, 92% chose to terminate. A lethal long-term prognosis was the only factor related to parental decision to terminate a pregnancy. CONCLUSIONS: Doctors mainly informed parents about the option of pregnancy termination for conditions with a poor or lethal long-term prognosis or for genetic disorders. Only conditions with a lethal prognosis were significantly related to the parental decision to terminate the pregnancy.

Parity and mode of birth and their relationships with quality of life: A longitudinal study.

OBJECTIVE: To examine how (a) parity and (b) mode of birth were associated with later Quality of Life (QOL) in young adult women, with a mean follow-up of 11.0 years. DESIGN: Prospective cohort study. SETTING: Australia. R SAMPLE: A total of 7770 women participating in the 1973-1978 cohort of the Longitudinal Study of Women's Health. METHODS: Linear regression models were used to estimate (1) prospective associations between parity and mode of birth with eight subscale and two summary scores of the SF36, assessed after a mean follow-up of 11 years., and (2) differences between SF36 scores at follow up for women in different parity and mode of birth categories. MAIN OUTCOME MEASURE: Quality of Life as measured by the SF36. RESULTS: Women experiencing no births (parity 0) and one birth (parity 1) had lower scores on all the physical health measures, and on some mental health measures, than women who had 2 births (parity 2) (all p<0.05). CONCLUSIONS: Parity and mode of birth may have long-term implications for women's physical and mental health. Both childless and women with only one child had poorer physical and mental health than their peers with two children. Women with only caesarean section(s) also had poorer health than women who had vaginal birth/s.

Landscaping the evidence of intimate partner violence and postpartum depression: a systematic review.

OBJECTIVE: To assess the evidence of the association between exposure to intimate partner violence (IPV) and postpartum depression. IPV during pregnancy can have immediate and long-term physical and mental health consequences for the family. Therefore, it has been hypothesised that IPV may affect the risk of developing postpartum depression. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, Embase, Global Health Library, Scopus and Google scholar were searched for published studies without restrictions on language, time or study design (up to May 2020). Studies were included if they assessed postpartum depression using the Edinburg Postnatal Depression Scale (cut-off≥10), among women who had been exposed to IPV (emotional, physical and/or sexual abuse). The quality of studies was judged according to the Newcastle-Ottawa scale. RESULTS: A total of 33 studies were included in the review (participants n=131 131). The majority of studies found an association between exposure to IPV and the development of signs of postpartum depression. Overall, studies measured both exposure and outcome in various ways and controlled for a vast number of different confounders. Thirty percent of the studies were set in low-income and lower-middle-income countries while the rest were set in upper-middle-income and high-income countries and the association did not differ across settings. Among the studies reporting adjusted OR (aOR) (n=26), the significant aOR ranged between 1.18 and 6.87 (95% CI 1.12 to 11.78). The majority of the studies were judged as 'good quality' (n=20/33). CONCLUSION: We found evidence of an association between exposure to IPV and the development of signs of postpartum depression. Meta-analysis or individual patient data meta-analysis is required to quantify the magnitude of the association between IPV and postpartum depression. PROSPERO REGISTRATION NUMBER: CRD42020209435.

Importance of Reporting Complete Procedures of Identifying Patients from the Danish National Patient Registry: The Case of Neonatal Jaundice and Epilepsy.

Objective: The Danish National Patient Registry (DNPR) is a valuable resource for medical and epidemiological Research. However, not all research articles fully described procedures they used to identify events. In this study, we compared two approaches in identifying persons with a disease diagnosis using neonatal jaundice and epilepsy as examples. Methods: A cohort of singletons born alive between the 1st January 1997 and the 30th November 2016 in Denmark was used for this purpose. Diagnostic information for a hospital contact in the registry included a primary diagnosis, secondary diagnoses, referral diagnoses, and additional information to a diagnosis (associated diagnoses), if any. Approach 1 identified patients of interest by considering all diagnostic information with exclusion of referral diagnoses only. Approach 2 identified patients of interest by additionally excluding diagnoses from a hospital contact that were coded with Z00 - Z99 of ICD-10 (for health service on examination and reproduction, etc.) as the main reason of the hospital contact. We presented the proportion of people with a diagnosis of neonatal jaundice and epilepsy by the two approaches and explored the potential explanations for the difference. Results: For the example of neonatal jaundice, the study population included N=1,186,683 persons. The proportion of children with a diagnosis of neonatal jaundice was 5.5% (n=66,736) by approach 1 and 3.9% (n=45,928) by approach 2. For the example of epilepsy, the study population included N=1,183,273 persons. The proportion of children with a diagnosis of epilepsy were 1.2% (n=14,604) by approach 1 and 0.9% (n=10,441) by approach 2. Discussion: This study demonstrated that the two approaches identified different proportion of persons with a diagnosis of neonatal jaundice and epilepsy. We advocated researchers report complete procedures of identifying patients for making research findings reproducible and comparable.

How do reproductive history and anthropometry in midlife relate to later risk of pelvic organ prolapse? A prospective cohort study.

INTRODUCTION AND HYPOTHESIS: The objective was to examine the association between reproductive and anthropometric factors and later risk of pelvic organ prolapse (POP). METHODS: We carried out a prospective cohort study including 11,114 female nurses > 44 years from the Danish Nurse Cohort. In 1993, the study population was recruited through the Danish Nurse Organization and self-reported data on age, height, weight, age at menarche, age at first birth and number of childbirths were obtained. POP diagnosis was obtained from the National Patient Registry. Risk of POP was estimated using COX regression and presented as hazard ratios (HR) with 95% confidence intervals (CI). RESULTS: Overall, 10% of the women received a diagnosis of POP within a median follow-up of 22 years. A 4% increase in risk of POP was seen for each increasing BMI (kg/m2) unit at baseline. Compared to women of normal weight, higher risks of POP were seen in overweight (HR 1.18: 1.02-1.36) and obese women (HR 1.33: 1.02-1.74), while underweight had a lower risk (HR 0.51: 0.27-0.95). Compared to women with one childbirth, women with no childbirths had a reduced risk of 57% while increased risks of 46%, 78% and 137% were observed in women with two, three and four childbirths. Women with menarche before the age of 12 tended to have a higher risk of POP as did women who were 30-33 years at their first childbirth. CONCLUSIONS: POP is a common health problem in women, and BMI and number of childbirths are strong predictors.

The temperature induced disruption process of amylopectin under ultrasonic treatments.

In this study, amylopectin was ultrasonicated at different temperatures to explore its disruption process. Results showed a significant decrease in amylopectin Mw after ultrasonic treatments and a retarded effect was detected with the increase of temperatures. The amylopectin disruption process fitted to the second order kinetic model (1/Mwt - 1/Mw0 = kt) and its disruption rate coefficient decreased from 2.203 × 10-8 to 0.986 × 10-8 mol/g min as the temperatures increased from 20 to 80 °C. This was ascribed to the higher vapour pressure and the lower viscosity of the solution at higher temperatures. Ultrasound induced break points preferentially occurred to B3 chains of amylopectin at higher temperatures which contributed to an increase of A chains, which because that amylopectin would be more extended at higher temperatures. The activation energy of amylopectin disruption was negative (-11.6 KJ/mol), which indicated that its scission process by ultrasound was essentially a mechanical action.

Effect of heat-moisture treatment on the structural and physicochemical characteristics of sand rice (Agriophyllum squarrosum) starch.

A small granule starch from sand rice (Agriophyllum squarrosum) was subjected to heat-moisture treatment (HMT) at different moisture contents (MCs,15%-30%). With MC≤20%, a higher MC resulted in increases in the starch orders (i.e., short-range and crystalline structure) with unchanged granule morphology. Nonetheless, a further elevated MC (>20%) gradually destroyed the granule morphology and starch orders. Also, HMT gradually vanished the lamellar structure as MC increased during HMT. These structural evolutions in HMT-modified starch resulted in greater thermal stability, higher pasting temperature, lower pasting viscosity and weakened digestibility. Particularly, HMT applied directly in sand rice starch at 20% MC obtained the highest amount of SDS and RS (23.6%), which was 2.2-fold higher than that of native starch. Therefore, the small granule sand rice starch can be modulated by HMT through controlled MC to expand their application range in food production.
