Negative pressure wound therapy (NPWT) is a very effective method in the treatment of dehiscent, infected, and non-healing wounds. Difficult wound healing occurs especially in late pregnancy due to the rapid enlargement of the uterus and the constantly increasing tension of the entire abdominal wall. In cases of dehiscence of the surgical wound during pregnancy, proper subsequent treatment is needed, where it is necessary to consider the safety of the mother as well as the fetus.

Background: Studies indicate that physical appearance changes affect a significant proportion of breast cancer survivors, often leading to post-surgical distress. Both reconstructive surgery and medical tattoos are associated with patient-reported satisfaction, yet further research is necessary to understand their combined impact on aesthetic outcomes from the patient perspective. This study examined how breast cancer survivors evaluated the cosmetic and decision satisfaction of other patients who made various cosmetic intervention choices post-mastectomy.

Objective: Prior research has indicated that outcome expectancies, sensitivity to punishment, and sensitivity to reward may predict harmful health behaviors concurrently, including disordered eating. Loss-of-control eating (LOCE), feeling unable to resist eating or stop once one has started, is associated with expectancies that eating alleviates negative affect (NA reduction expectancies) and expectancies that eating is rewarding (reward expectancies).

Method: A survey battery was administered examining LOCE pathology, sensitivity to punishment, sensitivity to reward, and eating expectancies to a sample of 1660 adults in the United States ( = 39.

Affect regulation models posit that aversive affective states drive binge-eating behavior, which then regulates negative emotions. However, recent findings among individuals with binge-eating disorder (BED) suggest that food-related anticipatory processes may precede and potentially explain the negative affect thought to drive binge eating. Specifically, studies using ecological momentary assessment (EMA) demonstrate that the negative affective state of "Guilt" (from the Positive and Negative Affect Schedule) most strongly predicts later binge eating in the natural environment, and it has been hypothesized that planning a binge or feeling that a binge-eating episode is inventible may account for the increases in Guilt observed prior to binge episodes.

Alcohol consumption and related problems are common among college students. Prior research links behavioral economic (BE) constructs of alcohol demand and relative reinforcement (RR), and alcohol expectancies, with alcohol consumption/problems. However, research has yet to examine the associations between BE, expectancy theory, and alcohol use outcomes.

Purpose: A review of the literature revealed a high incidence of body-image distress among breast cancer survivors who had surgery. This cross-sectional study examined the relationship between medical tattooing as a complementary cosmetic intervention and body-image distress and mental health outcomes among breast cancer survivors following surgery.

Methods: We examined 330 post-surgical breast cancer survivors collected through a nationwide online survey in the U.

Article Synopsis
  • * This study examines a specific intervention based on Deviance Regulation Theory (DRT), which utilizes targeted messaging to encourage responsible drinking, and its impact on emotional health among 147 participants from a Southeastern university.
  • * Results indicate that both positive and negative messaging from the intervention led to reductions in depressive and anxiety symptoms, while the control group showed no improvement, suggesting that the DRT intervention may positively influence mental health alongside promoting responsible drinking.

College students continue to report problematic alcohol use. To mitigate adverse outcomes, recent studies have employed harm reduction strategies known as Protective Behavioral Strategies (PBS). Deviance Regulation Theory (DRT), an impression management intervention, has been used to promote the use of PBS.

Objectives: Hispanic/Latinx drinkers have been found to experience more adverse alcohol-related consequences than any other racial/ethnic group. Due to this, researchers have looked at the connection between drinking and cultural factors, alongside discrimination, to further analyze what sociocultural factors lead to negative outcomes when drinking.

Design: Researchers used a sample of Hispanic/Latinx young adult drinkers (= 710) with an average age of 22.

Article Synopsis
  • The study focused on protective behavioral strategies (PBS) for alcohol use and tested a two-factor model against the traditionally used three-factor model from the PBSS-20 among nearly 4,900 drinkers.
  • Both models showed similar effectiveness, but the two-factor model was simpler and provided more straightforward measurement of PBS.
  • The research found that the two-factor model had negative relationships with alcohol consumption and problems, suggesting a clearer framework for understanding how PBS impact alcohol-related outcomes.

Undifferentiated carcinoma with osteoclast-like giant cells (UCOGC) of the pancreas is a rare malignancy regarded as a subvariant of pancreatic ductal carcinoma (PDAC) characterized by variable prognosis. UCOGC shows a strikingly similar spectrum of oncogenic DNA mutations to PDAC. In the current work, we analyzed the landscape of somatic mutations in a set of 13 UCOGC cases via next-generation sequencing (NGS).

  • * The Sexual and Negative Dating Inventory (SANDI) measures protective strategies in dating and sexual contexts, showing promise in reducing ASEs among college students, particularly in a sample of 313 SGM individuals.
  • * Although SANDI did not predict a history of sexual violence, it was associated with lower sexual risk and reduced regretted sex over time, emphasizing the need for protective behaviors tailored to diverse gender and sexual identities.

Sewage and water networks are crucial infrastructures of modern urban society. The uninterrupted functionality of these networks is paramount, necessitating regular maintenance and rehabilitation. In densely populated urban areas, trenchless methods, particularly those employing cured-in-place pipe technology, have emerged as the most cost-efficient approach for network rehabilitation.

Article Synopsis
  • Altered reward processing is linked to binge-eating disorder (BED), but the specific neurocognitive processes involved are not well understood.
  • In a study of 40 individuals with BED and 40 matched controls, EEG data showed that those with BED exhibited heightened brain activity for both anticipatory (CNV) and outcome-related (RewP) responses to food and money rewards.
  • Within the BED group, more frequent binge eating correlated with stronger anticipatory responses but weaker outcome responses to food, suggesting that while "wanting" food rewards is amplified in BED, the "liking" aspect may be diminished as disorder severity increases.

Objective: The goal of the current study was to better understand affect-drinking relations among those diagnosed with an alcohol use disorder (AUD), as recent meta-analytic work suggests that daily negative affect may not universally predict subsequent alcohol consumption in those nondependent on alcohol. Specifically, we investigated the between- and within-person effects of positive and negative affects on drinking.

Method: Participants (n = 92) who met AUD diagnostic criteria completed a 90-day daily assessment of drinking behavior and positive and negative affects.

When primary space radiation particles enter into the atmosphere of the Earth, they generate showers of secondary radiation. The intensity of secondary radiation reaches its maximum, called the Regener-Pfotzer maximum; its exact position depends on the geomagnetic effective vertical cut-off rigidity, the phase of the solar cycle and also on the type of detected particles. In this paper, several balloon flight experiments are described focusing on the study of the latitudinal effect on the position of the Regener-Pfotzer maximum.

Degeneration of midbrain dopaminergic (DA) neurons alters the connectivity and functionality of the basal ganglia-thalamocortical circuits in Parkinson's disease (PD). Particularly, the aberrant outputs of the primary motor cortex (M1) contribute to parkinsonian motor deficits. However, cortical adaptations at cellular and synaptic levels in parkinsonism remain poorly understood.
