A study of low-speed streaks (LSSs) embedded in the near-wall region of a turbulent boundary layer is performed using selective visualization and analysis of time-resolved tomographic particle image velocimetry (tomo-PIV). First, a three-dimensional velocity field database is acquired using time-resolved tomo-PIV for an early turbulent boundary layer. Second, detailed time-line flow patterns are obtained from the low-order reconstructed database using ‘tomographic visualizations’ by Lagrangian tracking. These time-line patterns compare remarkably well with previously observed patterns using hydrogen bubble flow visualization, and allow local identification of LSSs within the database. Third, the flow behaviour in proximity to selected LSSs is examined at varying wall distances (
$10 < y^+ < 100$
) and assessed using time-line and material surface evolution, to reveal the flow structure and evolution of a streak, and the flow structure evolving from streak development. It is observed that three-dimensional wave behaviour of the detected LSSs appears to develop into associated near-wall vortex flow structures, in a process somewhat similar to transitional boundary layer behaviour. Fourth, the presence of Lagrangian coherent structures is assessed in proximity to the LSSs using a Lagrangian-averaged vorticity deviation process. It is observed that quasi-streamwise vortices, adjacent to the sides of the streak-associated three-dimensional wave, precipitate an interaction with the streak. Finally, a hypothesis based on the behaviour of soliton-like coherent structures is made which explains the process of LSS formation, bursting behaviour and the generation of hairpin vortices. Comparison with other models is also discussed.
Patulous Eustachian tube appears to be caused by a concave defect in the anterolateral wall of the tubal valve of the Eustachian tube. This study aimed to compare the clinical features of patulous Eustachian tube patients with or without a defect in the anterolateral wall of the tubal valve.
Sixty-six patients with a patulous Eustachian tube completed a questionnaire, which was evaluated alongside endoscopic findings of the tympanic membrane, nasal cavity and Eustachian tube orifice.
Females were more frequently diagnosed with a patulous Eustachian tube, but the valve defect was more common in males (p = 0.007). The ratio of patulous Eustachian tube patients with or without defects in the anterolateral wall of the tubal valve was 1.6:1. Weight loss in the previous six months and being refractory to conservative management were significantly associated with the defect (p = 0.035 and 0.037, respectively). Symptom severity was significantly higher in patients with the defect.
Patulous Eustachian tube patients without a defect in the anterolateral wall of the tubal valve can be non-surgically treated more often than those with the defect. Identification of the defect could assist in making treatment decisions for patulous Eustachian tube patients.
To inform the efficient allocation of testing resources, we evaluated the characteristics of those tested for COVID-19 to determine predictors of a positive test. Recent travel and exposure to a confirmed case were both highly predictive of positive testing. Symptom-based screening strategies alone may be inadequate to control the ongoing pandemic.
Introduction: Assessment of point-of-care ultrasound (POCUS) competency has been reliant on practical, visual and written examinations performed 1-on-1 with an examiner. These tools attempt to assess competency through subjective ratings, checklists and multiple-choice questions that are labour intensive using surrogate measures. Eye-tracking has been used on a limited basis in various fields of medicine for training and assessment. This technology explores visual processing and holds great promise as a tool to monitor training progress towards the development of expertise. We hypothesize that eye-tracking may differentiate novices and experts as they progress to become competent in interpretation of POCUS images and provide an objective measure in assessment of competency. Methods: Medical students, residents and attending physicians working in an academic emergency department were recruited. Participants viewed a series of 16 ultrasound video clips in a POCUS protocol for Focused Assessment using Sonography in Trauma (FAST). The gaze pattern of the participants was recorded using a commercially available eye-tracking device. The primary outcome was the gaze parameters including total gaze time in the area of interest (AOI), average time to fixation on the AOI, number of fixations in the AOI and average duration of first fixation on the AOI. Secondary outcome was the accuracy on the interpretation of the FAST scan. Results: Four novices and eight experts completed this study. The total gaze time in the AOI (mean +/- SD) was 76.72 +/- 18.84s among experts vs 53.64 +/- 10.33s among novices (p = 0.048), average time to fixation on the AOI was 0.561 +/- 0.319s vs 1.048 +/- 0.280s (p = 0.027), number of fixations in the AOI was 158.9 +/- 29.0 vs 121.8 +/- 17.5 (p = 0.042) and average duration of first fixation was 0.444 +/- 0.119s vs 0.390 +/- 0.024s (p = 0.402). The accuracy of the answers was 79.7 +/- 14.1% vs 45.3 +/- 21.9% (p = 0.007). Conclusion: In this pilot study, eye tracking shows potential to differentiate between POCUS experts and novices by their gaze patterns. Gaze patterns captured by eye tracking may not necessarily translate to cognitive processing. However, it allows educators to visualise the thought processes of the learner by their gaze patterns and provide insight on how to guide them towards competency. Future studies are needed to further validate the metrics for competency in POCUS applications.
Bupropion is a catecholamine reuptake inhibitor and also a potent noncompetitive ion channel site antagonist at the nicotinic acetylcholine receptor. Bupropion is indicated for use in combination with behavioral modification programs for smoking cessation. There have been a few studies about the effect of bupropion on smoking cessation in schizophrenia. Therefore, we aimed investigated the change of the symptomatology after smoking cessation with bupropion in the patients with schizophrenia.
There were fifty-six patients with smoking in the psychiatric ward of Hapcheon Korea Hospital. among them, thirty-nine inpatients meeting the DSM-IV criteria for schizophrenia were recruited. for 4 weeks, treatment team persuaded the patients to enter the program of smoking cessation. with the exception, if the patients did not agree the program, the patients were able to be transferred to another ward that smoking was permitted. All patients agreed to the program. Postive and Negative Symptom Scale (PANSS), Temperament and Character Inventory(TCI), State-Trait Anxiety Inventory(STAI), Fagerstrom Test for Nicotine Dependence(FTND) were evaluated at the beginning of the study and 12 weeks of Bupropion treatment.
At 12 weeks after successful smoking cessation with bupropion, FTND scores were significantly decreased after smoking cessation. the scores of STAI and PANSS were not significantly changed. the subcale of TCI, Novelty Seeking showed decreasing tendency after smoking cessation, although there was no statistical significance(p=0.054).
These results suggest that bupropion is an effective antidepressant on smoking cessation and does not aggravate the psychotic symptoms in schizophrenia. Further investigation with larger number of subjects is needed.
Adherence problems are an inherent issue with any bio-psycho-social-spiritual prescription for any disease or behvaioural entity. It is all the more important in a patient with severe mental illness like Schizophrenia with limited insight. In several countries various interventions have been studied to address adherence problems in psychosis. Such as compliance therapy, family and psycho educational interventions, telephonic prompting and also legislative measures like Community Treatment Orders (CTO) have to date shown inconsistent and only modest benefits. Incentives based interventions have been tested for both preventive measures and also for adherence problems in chronic diseases. The Institute of Mental Health, Singapore has implemented a Pilot Supervision Programme (PSP) that incentivise patient engagement through quarterly vouchers as well as minimising barriers to accessing service by waiving off certain treatment fees whilst also offering them intensive intervention for one year. Our Pilot Programme, that focused on high risk patients with diagnosis of severe mental illness needing involuntary admission with history of either prolonged or repeated admissions, has begun recruiting patients since October 2012. The comparison was done between pre and post intervention phase. Total of 58 patients (95% suffering from schizophrenia or schizoaffective disorder) accepted into the treatment programme and of that nearly half of them have completed 6 months interventions. The results are promising with more than 50% improvemnt in length of stay, number of admissions and psychiatric emergency room visits, making significant impact on our high risk patients with severe mental illness.
There have been many changes in the treatment of bipolar disorder.
It is necessary to develop guidelines that can more aptly respond to cultural issues and specifics in different countries.
The Korean Medication Algorithm for Bipolar Disorder (KMAP-BP) was firstly published in 2002, with updates in 2006 and 2010. This third update reviewed the experts' consensus of opinion on the pharmacological treatments of bipolar disorder.
The newly revised questionnaire composed of 55 key questions about clinical situations including 223 sub-items was sent to the experts.
Combination of mood stabilizer (MS) and atypical antipsychotic (AAP) was the first-line treatment option in acute mania. For the management of severe psychotic bipolar depression, combination of MS and AAP, combination of AAP and LTG, combination of MS, AAP and AD or LTG, combination of AAP and AD, and combination of AAP, AD and LTG was the first-line treatments. Combination of MS and AAP was the treatment of choice for management of mixed features. Combination of MS and AAP, MS or AAP monotherapy was the first-line options for management of maintenance phase after manic episode. For maintenance treatment after bipolar I depression, combination of MS and AAP, combination of MS and LTG, combination of AAP and LTG, MS or LTG monotherapy, and combination of MS, AAP and LTG were the first-line options.
Despite the limitations of expert consensus guideline, KMAP-BP 2014 may reflect the current patterns of clinical practice and recent researches.
The prevalence of internet game use among children and adolescents has been increased in the recent years.
Internet addiction has been found to cause various psychiatric symptoms and psychological problems. Internet addiction has been found to cause various psychiatric symptoms and psychological problems.
The aim of this study was to examine the association between problematic internet game use and psychiatric symptoms in a sample of the Child and Adolescent Psychiatric Clinic, Ulsan University Hospital.
We analyzed data from 447 subjects who first visit the Child and Adolescent Psychiatric Clinic of the Ulsan University Hospital. The level of Internet addiction was categorized as either high-risk (≥108; group 3), potential risk (95 to 107; group 2), or no risk (≤94, group 1) based on the total score. Data were analyzed using SPSS version 17.0 and one-way ANOVA and multiple logistic regression method were used.
Thirteen adolescents met the criteria for high risk group of internet game addiction. in the high risk group, 10 were male and 3 were female adolescents. There was an mean difference among group 3 (high risk)< 1 (no risk),2 (potential risk) in AHI ; whereas group 3 (high risk)>1 (no risk), 2 (potential risk) in BDI, BAI, inattention, hyperactivity/impulsivity and K-ARS score. with multiple logistic regression analysis, K-scale was significantly related with male sex, BDI, ARShyperactivity/ impulsivity score.
We conclude that having male sex, happiness and depressive symptoms is associated with the risk of developing internet use disorders.
The aim of this study was to monitor changes of prescription trends for bipolar disorder in inpatient settings in one university hospital.
A retrospective chart review was performed and data of 188 cases (2009–2012) and 118 cases (1998–2001) with a diagnosis of bipolar disorder were collected. Data on demographic variables, duration of hospitalization, kinds of psychotropic medications and the patterns of prescription over each four-year period were analyzed.
The proportion of patients with manic episode was decreased, whereas those of mixed and depressive episodes were increased. The use of lithium was decreased with the increased use of valproate. Increased use of lamotrigine in depressive episode was prominent. The use of combination treatment with mood stabilizers and antipsychotics was almost same level in both periods. The use of typical antipsychotics was significantly decreased and that of atypical antipsychotics was increased. Especially, the use of quetiapine showed great increase. In bipolar depression, the use of antidepressant was increased.
Data showed that quetiapine monotherapy had favorable effect on acute manic symptoms and well tolerated. Also this result suggests that quetiapine monotherapy may improve the self-perceived quality of sleep without any daytime impairment following sleep in acute manic patients.
Life events and accompanying psychological and behavioral reactions frequently have an impact upon people's daily lives and are believed to predispose them to disease. Psychological stressors impact many physiological and pathological disease outcomes, including mental illness. Positive social interactions have in turn been shown to exert powerful beneficial effects on health outcomes and longevity.
The Objective of this study was to analyze the relationships of Psychological Distress, Social Support, and Mental Fitness among patients of mental health services.
This article aims to discuss the evidence supporting the mediating effect of social support between psychological stress and mental health.
This study was performed on patients who visited the mental health services in Daejeon from October to December 2011. In total, 395 patients were evaluated with Mental Fitness Scale, Kessler Psychological Distress Scale(KPDS), and Multidimensional Scale of Perceived Social Support(MSPSS).
Correlations among variables of psychological distress and social support on subordinate variable of mental fitness of patients were significant. The result of the regression analysis, psychological distress and social support have a positively significant influence on mental fitness of patients. social support showed mediating effects between psychological distress and mental fitness.
These results suggest that health care providers ought to seek social support for patients, in order to provide positive mental fitness of patients.
Impairments of attention and memory are evident in early psychosis, and often lead to severe, longstanding functional disability. Effective non-pharmacological interventions are needed due to the unsuccessful results of pharmacological interventions.
To determine whether yoga is effective for cognitive impairments, and the neural mechanism underlying these effects.
It was a randomized controlled study of 12-week of yoga and aerobic exercise (walking and cycling) intervention vs wait-list control for female early psychotic patients. Memory was measured with Hong Kong List Learning Test and Digit Span test, and attention was measured with Letter Cancellation test. Cognitive data analysis was based on the Intention-to-Treat method using a mixed-model analysis. Seed based functional connectivity was applied using posterior cingulate cortex (PCC) as seed with AFNI. Cortical thickness analyses were performed using FreeSurfer. Results from yoga and control groups were presented.
A total of 140 women were recruited and randomized into three groups. 95 completed the study, and 115 were included for cognitive data analysis. For imaging data, 42 participants were used for cortical thickness analyses; and 60 were included for neural connectivity analyses. Yoga group demonstrated significant improvements in working memory, verbal acquisition and attention (P=.01). Cortical thickness increased in the postcentral gyrus (P<.01); connectivity between PCC and bilateral inferior parietal gyrus increased after yoga intervention (P<.005).
Yoga has been found to be effective for memory and attention in early psychotic patients. The increases of thickness and neural connectivity indicate the possible neural mechanisms underlying the improvements of cognition.
Despite the advance in pharmacotherapy for posttraumatic stress disorder (PTSD), poor treatment adherence to pharmacotherapy for PTSD is a critical issue.
We intended to evaluate the predictors of premature discontinuation of psychiatric outpatient treatment after discharge for noncombat-related PTSD.
This study aimed to examine the sociodemographic and disease-related variables associated with the premature discontinuation of psychiatric outpatient treatment after discharge among patients with non-combat-related posttraumatic stress disorder.
We retrospectively reviewed the medical records of patients who were discharged with a diagnosis of posttraumatic stress disorder.
Fifty-five percent of subjects prematurely discontinued outpatient treatment within 6 months of discharge. Comparing sociodemographic variables between the 6-month non-follow-up group and 6-month follow-up group, there were no variables that differed between the two groups. However, comparing disease-related variables, the 6-month follow-up group showed a longer hospitalization duration and higher Global Assessment of Function score at discharge. The logistic regression analysis showed that a shorter duration of hospitalization predicted premature discontinuation of outpatient treatment within 6 months of discharge.
The duration of psychiatric hospitalization for posttraumatic stress disorder appeared to influence the premature discontinuation of outpatient treatment after discharge.
This study examined the prescribing patterns for medications to treat bipolar disorder in outpatient-based psychiatric practice focusing on atypical antipsychotics.
Retrospective chart review of patients admitted to a university hospital with a primary diagnosis of bipolar disorder in a period from January 2008 to December 2012 was conducted. We reviewed Diagnostic and Statistical Manual of Mental Disorders, fourth edition diagnosis and detailed clinical information at index episode. Psychotropic medications were grouped into six categories; atypical antipsychotics, typical antipsychotics, lithium, anticonvulsants, antidepressants, and minor tranquilizers. Severity, rapid cycling type, psychiatric comorbidity and disease duration were computed focusing on atypical antipsychotics.
In 344 patients who were prescribed major psychotropic medications, atypical antipsychotics were prescribed in 70.9% of subjects, anticonvulsants in 73.3%, lithium in 36.9%, antidepressants in 41.9%, and typical antipsychotics in 0.9% of subjects. About 12.5% of subjects were treated with the monotherapy. Atypical antipsychotics prescription was favored in subjects with manic and mixed episodes or severe episode. Prescribing trend is independent of rapid cycling type. Prescription of antidepressants were more frequent in subjects who were recently diagnosed as bipolar disorder or prescribed new medications or existed psychiatric comorbidity.
The development of bipolar disorder's psychopharmacology has been reflected in the prescription pattern of psychotropic medications in Korea. This study suggests that atypical antipsychotics have played major role in treatment of bipolar disorder.
We evaluated the difference in sleep skills between patients with and without need of hypnotics after sleep CBT.
Total 131 insomnia patients' sleep disturbances were assessed by visual analogue scales. Patients received 9 sessions of sleep CBT and were prescribed hypnotics for prn during 3 months. Sleep CBT was focused on the sleep hygiene and sleep stimulus-control guidelines. Sleep hygiene guidelines were Limit the time spent in bed (SH1), Get regular exercise (SH2), Avoid light at night (SH3), Avoid heavy meals or drinking (SH4), Quiet, dark, and comfortable bedroom (SH5), Avoid caffeine, alcohol, and nicotine (SH6), Relaxing bedtime routine (SH7),Llight bedtime snack (SH8), Remove the bedroom clock (SH9). Sleep stimulus-control guidelines were Go to bed only when sleepy (SSC1), Use the bed for sleeping or sex (SSC2), Get out of bed when unable to sleep (SSC3), Get up at the same time (SSC4), Avoid napping (SSC5). Each sleep skill state was evaluated by Likert scale, and they were compared between before and after CBT. Patients were divided into two groups: still need of hypnotics and no need of hypnotics after 3 months.
Forty-six (35.1%) patients replied they needed not hypnotics any more, but 85 (64.9%) patients replied they still needed hypnotics after CBT. Sleep VAS (25.26±8.52 vs. 32.64±8.95, p<0.001), SH2 (3.67±0.92 vs. 2.76±1.06, p=0.030), SH7 (4.08±0.55 vs. 2.76±0.76, p<0.001) were different in two groups.
Among several CBT skills, regular moderate exercise in daytime and a relaxing bedtime routine seem to be key components.
Patients with distributive shock who are unresponsive to traditional vasopressors are commonly considered to have severe distributive shock and are at high mortality risk. Here, we assess the cost-effectiveness of adding angiotensin II to the standard of care (SOC) for severe distributive shock in the US critical care setting from a US payer perspective.
Short-term mortality outcomes were based on 28-day survival rates from the ATHOS-3 study. Long-term outcomes were extrapolated to lifetime survival using individually estimated life expectancies for survivors. Resource use and adverse event costs were drawn from the published literature. Health outcomes evaluated were lives saved, life-years gained, and quality-adjusted life-years (QALYs) gained using utility estimates for the US adult population weighted for sepsis mortality. Deterministic and probabilistic sensitivity analyses assessed uncertainty around results. We analyzed patients with severe distributive shock from the ATHOS-3 clinical trial.
The addition of angiotensin II to the SOC saved .08 lives at Day 28 compared to SOC alone. The cost per life saved was estimated to be $108,884. The addition of angiotensin II to the SOC was projected to result in a gain of .96 life-years and .66 QALYs. This resulted in an incremental cost-effectiveness ratio of $12,843 per QALY. The probability of angiotensin II being cost-effective at a threshold of $50,000 per QALY was 86 percent.
For treatment of severe distributive shock, angiotensin II is cost-effective at acceptable thresholds.
Heat shock proteins (HSPs) consist of highly preserved stress proteins that are expressed in response to stress. Two studies were carried out to investigate whether HSP genes in hair follicles from beef calves can be suggested as indicators of heat stress (HS). In study 1, hair follicles were harvested from three male Hanwoo calves (aged 172.2 ± 7.20 days) on six dates over the period of 10 April to 9 August 2017. These days provided varying temperature–humidity indices (THIs). In study 2, 16 Hanwoo male calves (aged 169.6 ± 4.60 days, with a BW of 136.9 ± 6.23 kg) were maintained (4 calves per experiment) in environmentally controlled chambers. A completely randomized design with a 2 × 4 factorial arrangement involving two periods (thermoneutral: TN; HS) and four THI treatment groups (threshold: THI = 68 to 70; mild: THI = 74 to 76; moderate THI = 81 to 83; severe: THI = 88 to 90). The calves in the different group were subjected to ambient temperature (22°C) for 7 days (TN) and subsequently to the temperature and humidity corresponding to the target THI level for 21 days (HS). Every three days (at 1400 h) during both the TN and HS periods, the heart rate (HR) and rectal temperature (RT) of each individual were measured, and hair follicles were subsequently collected from the tails of each individual. In study 1, the high variation (P < 0.0001) in THI indicated that the external environment influenced the HS to different extents. The expression levels of the HSP70 and HSP90 genes at the high-THI level were higher (P = 0.0120, P = 0.0002) than those at the low-THI level. In study 2, no differences in the THI (P = 0.2638), HR (P = 0.2181) or RT (P = 0.3846) were found among the groups during the TN period, whereas differences in these indices (P < 0.0001, P < 0.0001 and P < 0.0001, respectively) were observed during the HS period. The expression levels of the HSP70 (P = 0.0010, moderate; P = 0.0065, severe) and HSP90 (P = 0.0040, severe) genes were increased after rapid exposure to heat-stress conditions (moderate and severe levels). We conclude that HSP gene expression in hair follicles provides precise and accurate data for evaluating HS and can be considered a novel indicator of HS in Hanwoo calves maintained in both external and climatic chambers.
The practice of foodborne illness outbreak investigations has evolved, shifting away from large-scale community case-control studies towards more focused case exposure assessments and sub-cluster investigations to identify contaminated food sources. Criteria to include or exclude cases are established to increase the efficiency of epidemiological analyses and traceback activities, but these criteria can also affect the investigator's ability to implicate a suspected food vehicle. A 2010 outbreak of Salmonella ser. Hvittingfoss infections associated with a chain of quick-service restaurants (Chain A) provided a useful case study on the impact of exclusion criteria on the ability to identify a food vehicle. In the original investigation, a case-control study of restaurant-associated cases and well meal companions was conducted at the ingredient level to identify a suspected food vehicle; however, 21% of cases and 22% of well meal companions were excluded for eating at Chain A restaurants more than once during the outbreak. The objective of this study was to explore how this decision affected the results of the outbreak investigation.
Epidemiological studies indicate that individuals with one type of mental disorder have an increased risk of subsequently developing other types of mental disorders. This study aimed to undertake a comprehensive analysis of pair-wise lifetime comorbidity across a range of common mental disorders based on a diverse range of population-based surveys.
The WHO World Mental Health (WMH) surveys assessed 145 990 adult respondents from 27 countries. Based on retrospectively-reported age-of-onset for 24 DSM-IV mental disorders, associations were examined between all 548 logically possible temporally-ordered disorder pairs. Overall and time-dependent hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards models. Absolute risks were estimated using the product-limit method. Estimates were generated separately for men and women.
Each prior lifetime mental disorder was associated with an increased risk of subsequent first onset of each other disorder. The median HR was 12.1 (mean = 14.4; range 5.2–110.8, interquartile range = 6.0–19.4). The HRs were most prominent between closely-related mental disorder types and in the first 1–2 years after the onset of the prior disorder. Although HRs declined with time since prior disorder, significantly elevated risk of subsequent comorbidity persisted for at least 15 years. Appreciable absolute risks of secondary disorders were found over time for many pairs.
Survey data from a range of sites confirms that comorbidity between mental disorders is common. Understanding the risks of temporally secondary disorders may help design practical programs for primary prevention of secondary disorders.
Post-traumatic stress disorder (PTSD) is a serious mental disorder that develops in some individuals following exposure to severe psychological stressors. In this chapter, we provide an overview of the conceptual issues, specific methods, and practical considerations in evidence-based assessment of PTSD. First, we outline the conceptual issues and practical components of a comprehensive assessment of PTSD. Second, we provide an overview of the most widely used self-rated and clinician-rated measures of trauma exposure and PTSD, comorbid disorders, and response bias. Third, we discuss cultural considerations in assessing PTSD. Fourth, we offer practical guidelines for conducting a clinically sensitive assessment of PTSD, highlighting some of the unique considerations in engaging trauma survivors in the assessment process and optimizing the information obtained. Last, we briefly summarize conceptual considerations and specific measures for other trauma- and stressor-related disorders.
Maternal systemic inflammation during pregnancy may restrict embryo−fetal growth, but the extent of this effect remains poorly established in undernourished populations. In a cohort of 653 maternal−newborn dyads participating in a multi-armed, micronutrient supplementation trial in southern Nepal, we investigated associations between maternal inflammation, assessed by serum α1-acid glycoprotein and C-reactive protein, in the first and third trimesters of pregnancy, and newborn weight, length and head and chest circumferences. Median (IQR) maternal concentrations in α1-acid glycoprotein and C-reactive protein in the first and third trimesters were 0.65 (0.53–0.76) and 0.40 (0.33–0.50) g/l, and 0.56 (0.25–1.54) and 1.07 (0.43–2.32) mg/l, respectively. α1-acid glycoprotein was inversely associated with birth size: weight, length, head circumference and chest circumference were lower by 116 g (P = 2.3 × 10−6), and 0.45 (P = 3.1 × 10−5), 0.18 (P = 0.0191) and 0.48 (P = 1.7 × 10−7) cm, respectively, per 50% increase in α1-acid glycoprotein averaged across both trimesters. Adjustment for maternal age, parity, gestational age, nutritional and socio-economic status and daily micronutrient supplementation failed to alter any association. Serum C-reactive protein concentration was largely unassociated with newborn size. In rural Nepal, birth size was inversely associated with low-grade, chronic inflammation during pregnancy as indicated by serum α1-acid glycoprotein.
