A case report of adenomyosis-induced spontaneous rupture in an unscarred and unpregnant uterus.

Rationale: Spontaneous uterine rupture, although rare, is a life-threatening obstetric emergency with a high maternal and fetal mortality rate. It can occur without warning, leading to severe complications, including hemorrhage, shock, and fetal demise. The risk factors contributing to uterine rupture are diverse and include a history of uterine surgery (such as cesarean section), trauma to the uterus, abnormal uterine contractions during labor, and underlying conditions like adenomyosis.

NEONATAL RHABDOMYOLYSIS: A CASE REPORT AND REVIEW OF THE LITERATURE.

Rhabdomyolysis is a potentially life-threatening condition in pediatric patients, often triggered by various factors, such as infections, trauma, hereditary metabolic disorders, and certain medications. Elevated creatine kinase levels are commonly observed in newborns and are often attributed to factors such as hypoxia, labor dystocia, and birth trauma. However, rhabdomyolysis in this population is rare and typically associated with hereditary metabolic disorders, medications, or infections.

Clinical Utility of Bone Turnover Markers in Chronic Kidney Disease.

Chronic kidney disease (CKD) often leads to mineral and bone disorders (CKD-MBDs), which are nearly universal in patients undergoing dialysis. CKD-MBD includes abnormal calcium-phosphate metabolism, vascular and soft tissue calcification, and bone abnormalities (renal osteodystrophy [ROD]). Bone fragility in CKD occurs due to low bone mass and poor bone quality, and patients with CKD have higher fracture and mortality rates.

On causal inferences from retrospective and observational studies and their implications for neuraxial labor analgesia: the CHRISTMAS* study.

Background: Observational studies should not be used to infer causation as they are prone to confounding factors, selection bias, and reverse causality. Many observational studies of labor analgesia treated epidurals as an independent exposure and concluded that "epidurals" cause dystocia, despite multiple randomized controlled trials showing no effect. We highlight this problem using reductio ad absurdum.

Unplanned Cesarean for Abnormal or Indeterminate Fetal Heart Tracing Varies Significantly by Race and Ethnicity.

Introduction: The US maternity care system achieves worse outcomes for birthing people identifying as Black versus White. Assessment of fetal well-being in labor is an area of perinatal care subject to significant interobserver variability and therefore may be at particular risk of medical racism influencing care.

Methods: Statewide collaborative quality initiative data, focused on decreasing the nulliparous, term, singleton, vertex (NTSV) cesarean birth rate, were used to conduct a retrospective cohort study to assess differences in cesarean birth for nonreassuring fetal status between birthing people identifying as Black compared with White.

The effects of age and sex on reference intervals for cobalamin, homocysteine, and serum and urinary methylmalonic acid in healthy adult dogs.

Background: In dogs, data on reference intervals (RIs) for cobalamin, markers of metabolism (markersBmet), age and sex effects are limited.

Hypothesis/objectives: Establish RI for serum cobalamin, homocysteine, and methylmalonic acid (sMMA) concentrations, urinary methylmalonic acid-to-creatinine ratio (uMMA:crea), and determine effects of sex and age.

Methods: Prospective study using healthy dogs (1-10 years).

More than the passage of time: neonatal health and active labor duration, the mediating role of chorioamnionitis.

Background: Labor intervention is intended to prevent perinatal morbidity and mortality. Labor durations traditionally defined as 'dystocia' drive primary cesarean birth rates, yet there is mixed evidence about the association between labor duration and poor neonatal outcomes. Using latent class analysis to study unknown patterns of neonatal health can refine understanding of these relationships and effect of labor duration on newborn outcomes.

Sire mating advice framework for cattle to recommend which beef bull to mate to individual dairy females.

A decision support tool or system is a computerized information system used to support decision-making in a business; one central component to profitable dairy cattle production systems is the appropriate mating of bulls and females. While tools have been described to aid mating decisions between dairy bulls and dairy females, or between beef bulls and beef females, there is a void of such tools that recommend which beef bull to mate to individual dairy females. The objective of the present study was to develop and validate a framework, founded on linear programming, to aid herd-level mating decisions where the bull-female mating is tailored based on complementarity and compatibility of both mates; consideration in the process was given to the genetic merit of both mates for a series of traits as well as the life history of the female herself.

Maternal and neonatal outcomes after a more interventional versus a more expectant management of the second stage of labor: A retrospective multicenter study.

Background: The optimal duration of second stage of labor has been largely discussed in literature, but there are no uniformly accepted contemporary criteria for defining normal or abnormal length. Available evidence suggests that longer duration of second stage of labor is associated with a lower rate of spontaneous vaginal delivery and increased maternal morbidity. On the neonatal side, it seems that longer second stage doesn't affect new-born morbidity, in a context of very rare neonatal complications.

Synergistic Clinico-Radiological Assessment of Term Newborns Afflicted by Birth Asphyxia in a Tertiary Medical Center: A Prospective Observational Study.

Background and objectives Hypoxic-ischemic encephalopathy (HIE) remains a critical concern in newborns, with therapeutic hypothermia (TH) serving as a key treatment strategy. However, assessing long-term outcomes requires a comprehensive approach, as children may develop neuropsychological and learning challenges even in the absence of noticeable motor impairments. This study aims to explore the correlation between electroencephalography (EEG) and neuroimaging findings with the clinical severity of HIE.

Feline dystocia and kitten mortality up to 12 weeks in pedigree cats.

Objectives: The aim of the present study was to establish the incidence of dystocia in pedigree cat breeds and investigate mortality rates in kittens up to the age of 12 weeks.

Methods: A retrospective study was conducted that utilised convenience sampling. Registered cat breeders from 29 countries whose cats had given birth within a single year (2019) were asked to complete an online questionnaire.

Quantifying the impact of frequent diseases and syndromes on calf health using the opinions of producers and veterinarians: Towards dairy calf disability weights.

The first objective of this study was to quantify the impact and disability weight (DW) of frequent diseases or syndromes of pre-weaned dairy calves using the perceptions of producers and veterinarians. The second objective was to compare the opinions of producers and veterinarians regarding the impact and DW of dairy calves' frequent diseases and syndromes. A survey was conducted to obtain demographic information and opinions of 39 dairy producers and 52 veterinarians on the impact of frequent disease and syndromes on calf health.

Associations between serum indium levels and preserved ratio impaired spirometry among non-smoking industrial workers: A nationwide cross-sectional study in Taiwan.

Background: Indium, a rare heavy metal, extensively used in flat panel display manufacturing, poses potential respiratory health risks to workers. Preserved ratio impaired spirometry (PRISm), a term describing nonobstructive lung function abnormalities, is associated with adverse health outcomes. Despite known risks, the relationship between serum indium levels and PRISm remains underexplored.

Development of criteria to optimize manual smear review of automated complete blood counts using a machine learning model.

Objective: In this study, we aim to determine if machine learning can reduce manual smear review (MSR) rates while meeting or exceeding the performance of traditional MSR criteria.

Method: 9938 automated CBCs with paired MSRs were performed on samples from rhesus and cynomolgus macaques. The definition of a positive (abnormal) smear was determined.

Analysis of the outcomes and factors influencing vaginal trial labor in primiparas at term.

Purpose: To explore the outcomes and factors influencing vaginal trial labor in primiparas with term singleton fetuses.

Methods: A retrospective analysis of 9174 first-time mothers who opted for a vaginal trial of labor at Peking University First Hospital from October 2019 to September 2022 was performed. The primary outcomes included the outcome of the trial of labor and influencing factors.

Analysis of Risk Factors and Establishment of a Risk Prediction Model for Severe Postpartum Haemorrhage.

Severe postpartum haemorrhage (PPH) is a dangerous condition, characterized by rapid progression and poor prognosis. It remains the leading preventable cause of maternal death worldwide. This study aimed to investigate the risk factors for severe PPH and establish a prediction model to identify severe PPH early, allowing for early intervention reduce maternal death.
