RESUMEN

Postpartum depression (PPD) symptoms can negatively influence mother-infant interactions. Video-Feedback Interaction Guidance for Improving Interactions Between Depressed Mothers and their Infants (VID-KIDS) is a parenting intervention that allows mothers experiencing PPD symptoms to observe and improve their interactions with their infants. VID-KIDS has also positively influenced infants' stress (cortisol) patterns. There is limited research on maternal perspectives of interventions like VID-KIDS. In this hermeneutic study, four mothers were interviewed to increase understanding of the VID-KIDS experience. Key findings included: 1) VID-KIDS provided an opportunity for mothers with PPD symptoms to positively transform their identity; 2) VID-KIDS provided a chance to witness the mother-infant relationship forming and improve maternal mental health t, and; 3) VID-KIDS provided a space for mothers to dialogue about their experience with PPD symptoms authentically. VID-KIDS promoted healing from PPD as mothers experienced a transformation in how they perceived themselves and their relationships with their infants.

RESUMEN

A 20-month-old female spayed Staffordshire Terrier (22.3 kg) presented to the Orthopedic Surgery Service at North Carolina State University Veterinary Teaching Hospital for evaluation of a 6-week history of toe-touching to nonweight-bearing lameness in the right hind limb. Radiographs of the right stifle revealed a multiloculated lytic lesion of the distal femur, with a large open lytic zone centrally, numerous osseous septations peripherally, and focal areas of cortical thinning and loss. An aspirate of the right distal femoral lesion yielded mildly cloudy serosanguineous fluid. Cytologic examination of the fluid revealed a pleomorphic population of discrete cells that exhibited marked anisocytosis and anisokaryosis and a variable nuclear-to-cytoplasmic (N:C) ratio, which were interpreted as probable neoplastic cells, with few macrophages, and evidence of hemorrhage. Given the clinical signs of pain, lesion size, and concern for malignant neoplasia, amputation of the right hind limb was performed. Histologically, the lesion had undulating walls 1-3 mm thick with a continuous outer layer of dense fibrous tissue and an inner layer composed of reactive cancellous bone with no cortical compacta remaining. Remnants of thin fibrous or fibro-osseous septa projected from the bony wall into the cyst lumen. The final histologic diagnosis was a benign multiloculated solitary (unicameral) bone cyst of the distal right femur. Based on the histopathologic findings, it was speculated that the cells identified on cytology were a mixture of developing osteoclasts, osteoblasts, endothelial, and stromal cells. This is the first report describing the cytologic examination of a solitary bone cyst in veterinary medicine.

RESUMEN

Brain development involves extensive migration of neurons. Microtubules (MTs) are key cellular effectors of neuronal displacement that are assembled from α/ß-tubulin heterodimers. Mutation of the α-tubulin isotype TUBA1A is associated with cortical malformations in humans. In this study, we provide detailed in vivo and in vitro analyses of Tuba1a mutants. In mice carrying a Tuba1a missense mutation (S140G), neurons accumulate, and glial cells are dispersed along the rostral migratory stream in postnatal and adult brains. Live imaging of Tuba1a-mutant neurons revealed slowed migration and increased neuronal branching, which correlated with directionality alterations and perturbed nucleus-centrosome (N-C) coupling. Tuba1a mutation led to increased straightness of newly polymerized MTs, and structural modeling data suggest a conformational change in the α/ß-tubulin heterodimer. We show that Tuba8, another α-tubulin isotype previously associated with cortical malformations, has altered function compared with Tuba1a. Our work shows that Tuba1a plays an essential, noncompensated role in neuronal saltatory migration in vivo and highlights the importance of MT flexibility in N-C coupling and neuronal-branching regulation during neuronal migration.

RESUMEN

An adult nematode was grossly identified in the meninges of a Malayan sambar (Rusa unicolor equina), with numerous microfilariae associated with encephalitis and vasculitis on histopathology. The nematode was confirmed to be Elaeophora schneideri by sequencing a portion of the 18S rRNA gene. Our report highlights the potential for aberrant migration of E. schneideri in exotic deer species and the use of advanced testing to specifically identify this metazoan parasite, avoiding misidentification of Parelaphostrongylus tenuis.

RESUMEN

African swine fever is a haemorrhagic disease in pig production that can have disastrous financial consequences for farming. No vaccines are currently available and animal slaughtering or area zoning to restrict risk-related movements are the only effective measures to prevent the spread of the disease. Ornithodoros soft ticks are known to transmit the African swine fever virus (ASFV) to pigs in farms, following the natural epidemiologic cycle of the virus. Tick saliva has been shown to modulate the host physiological and immunological responses during feeding on skin, thus affecting viral infection. To better understand the interaction between soft tick, ASFV and pig at the bite location and the possible influence of tick saliva on pig infection by ASFV, salivary gland extract (SGE) of Ornithodoros porcinus, co-inoculated or not with ASFV, was used for intradermal auricular inoculation. Our results showed that, after the virus triggered the disease, pigs inoculated with virus and SGE presented greater hyperthermia than pigs inoculated with virus alone. The density of Langerhans cells was modulated at the tick bite or inoculation site, either through recruitment by ASFV or inhibition by SGE. Additionally, SGE and virus induced macrophage recruitment each. This effect was enhanced when they were co-inoculated. Finally, the co-inoculation of SGE and virus delayed the early local spread of virus to the first lymph node on the inoculation side. This study has shown that the effect of SGE was powerful enough to be quantified in pig both on the systemic and local immune response. We believe this model should be developed with infected tick and could improve knowledge of both tick vector competence and tick saliva immunomodulation.

RESUMEN

This article investigates how a one-to-one support process based on the use of a whole dairy farm simulation tool helps both farmers to reflect on their production strategies and researchers to better understand the farmers' contexts of action and decision. The support process consists of a minimum of four discussion sessions with the farmer: designing the Initial Scenario and formulating a diagnosis, building and simulating the Project Scenario corresponding to the objective targeted by the farmer, building and comparing alternative scenarios proposed both by the farmer and the researcher, and evaluating the process with the farmer. The approach was tested with six smallholder farmers in Brazil. It is illustrated with the example of one farmer who aimed to develop his milk production by more than doubling his herd size on the same cultivated area. Two other examples illustrate the diversity of issues addressed with this approach. The first estimates the sensitivity of economic results to price variations of milk and concentrates. The second compares two scenarios in terms of forage supply autonomy. The discussion assesses the outcomes of the approach for farmers in terms of response to their specific issues and of knowledge acquired. The research outputs are discussed in terms of the value and limits of using simulation tools within both participatory action research and advisory processes.

RESUMEN

In most insects, the endosymbiont Wolbachia induces cytoplasmic incompatibility (CI), an embryonic mortality observed when infected males mate either with uninfected females or with females infected by an incompatible Wolbachia strain. Although the molecular mechanism of CI remains elusive, it is classically viewed as a modification-rescue model, in which a Wolbachia mod function disables the reproductive success of the sperm of infected males, unless eggs are infected and express a compatible resc function. The extent to which the modification-rescue model can predict highly complex CI pattern remains a challenging issue. Here, we show the rapid evolution of the mod-resc system in the Culex pipiens mosquito. We have surveyed four incompatible laboratory isofemale lines over 50 generations and observed in two of them that CI has evolved from complete to partial incompatibility (i.e. the production of a mixture of compatible and incompatible clutches). Emergence of the new CI types depends only on Wolbachia determinants and can be simply explained by the gain of new resc functions. Evolution of CI types in Cx. pipiens thus appears as a gradual process, in which one or several resc functions can coexist in the same individual host in addition to the ones involved in the self-compatibility. Our data identified CI as a very dynamic process. We suggest that ancestral and mutant Wolbachia expressing distinct resc functions can co-infect individual hosts, opening the possibility for the mod functions to evolve subsequently. This gives a first clue towards the understanding of how Wolbachia reached highly complex CI pattern in host populations.

RESUMEN

OBJECTIVE: We examined the impact of an aspart insulin protocol for treatment of hyperglycemia in the emergency department (ED) coupled with rapid initiation of a detemir-aspart insulin protocol for patients admitted to the hospital. RESEARCH DESIGN AND METHODS: ED patients with type 2 diabetes mellitus and a blood glucose (BG) ≥ 200 mg/dL were randomized to intervention (INT) or usual care (UC). INT patients (n = 87) received aspart every 2 hours when BG > 200 mg/dL, and if admitted, began daily detemir in the ED. UC patients (n = 89) were treated per hospital physicians. RESULTS: The initial ED BG was 304 ± 76 mg/dL. The final ED BG differed: 217 ± 71 mg/dL for INT patients versus 257 ± 89 mg/dL for UC patients (P < .01). No INT patients and 3 UC patients had a BG < 50 mg/dL (P = .5). ED length of stay (LOS) was similar: 5.4 ± 1.8 hours for INT patients versus 4.9 ± 1.9 hours for UC patients (P = .06). Sixty-nine percent from each group were admitted. Admission BG was 184 ± 74 mg/dL for INT patients versus 224 ± 93 mg/dL for UC patients (P < .01). Patient-day weighted mean glucose was 163 ± 39 mg/dL for INT patients versus 202 ± 39 mg/dL for UC patients (P < .01). One INT patient and 6 UC patients had a BG < 50 mg/dL (P = .11). Hospital LOS was similar: 2.7 ± 2.0 versus 3.1 ± 1.9 days, respectively (P = .58). CONCLUSIONS: An aspart insulin protocol safely lowers BG levels in the ED without prolonging LOS. During hospitalization, a detemir-aspart protocol achieves significantly better glycemic control compared with guideline-driven use of NPH-aspart or glargine/detemir-aspart (usual care) without increasing hypoglycemia. Standardization of insulin protocols in the ED and hospital settings leads to improvement in overall glycemic control with greater safety and efficacy than usual care.

RESUMEN

This study examined posttraumatic growth (PTG) in Non-Hispanic White (NHW; n = 132) and Hispanic (HISP; n = 51) women who had been diagnosed with cervical cancer. Participants completed measures of PTG, spirituality, optimism, stage of cancer, and demographics variables. The results showed that women with cervical cancer reported PTG but at lower levels than in studies of women with breast cancer. Greater spirituality and more advanced cancer stage predicted more PTG, but optimism did not predict PTG. HISP women reported higher levels of PTG than NHW women, and greater spirituality in the HISP women partially accounted for the difference.

RESUMEN

OBJECTIVE: The aim of this study was to identify individual differences associated with the willingness to use complementary and alternative medicine (CAM). DESIGN: A questionnaire was administered and the relationship between individual differences and the willingness to use CAM was examined using correlation and multiple regression analyses. PARTICIPANTS: The sample consisted of 276 undergraduate students (64% female) of diverse ethnicity (43% white, 33% Hispanic, 8% Native American, 16% other) and a wide range of incomes. MEASURES: The willingness to use 16 types of CAM was assessed for six categories: whole medical systems, mind-body medicine, biologically based practices, manipulative and body-based practices, energy medicine, and spiritually based practices. The individual differences assessed included age, gender, income, ethnicity, the Big Five personality characteristics, optimism, spirituality, religiosity, and three aspects of emotional intelligence: mood attention, mood clarity, and mood repair. RESULTS: The individual differences accounted for approximately one fifth of the variance in overall willingness to use CAM. Openness to experience, spirituality, and mood attention were the strongest predictors of overall willingness to use CAM and were related to the willingness to use most of the individual types of CAM. Older age or female gender was related to greater willingness to use most of the mind-body medicines. Hispanic ethnicity was related to greater willingness to use curanderismo, and Native American ethnicity was related to greater willingness to use Native American medicine and a spiritual/faith healer.

RESUMEN

BACKGROUND: While resilience has been defined as resistance to illness, adaptation, and thriving, the ability to bounce back or recover from stress is closest to its original meaning. Previous resilience measures assess resources that may promote resilience rather than recovery, resistance, adaptation, or thriving. PURPOSE: To test a new brief resilience scale. METHOD: The brief resilience scale (BRS) was created to assess the ability to bounce back or recover from stress. Its psychometric characteristics were examined in four samples, including two student samples and samples with cardiac and chronic pain patients. RESULTS: The BRS was reliable and measured as a unitary construct. It was predictably related to personal characteristics, social relations, coping, and health in all samples. It was negatively related to anxiety, depression, negative affect, and physical symptoms when other resilience measures and optimism, social support, and Type D personality (high negative affect and high social inhibition) were controlled. There were large differences in BRS scores between cardiac patients with and without Type D and women with and without fibromyalgia. CONCLUSION: The BRS is a reliable means of assessing resilience as the ability to bounce back or recover from stress and may provide unique and important information about people coping with health-related stressors.

RESUMEN

OBJECTIVES: The objective of this pilot study was to compare the effects of two mind-body interventions: mindfulness-based stress reduction (MBSR) and cognitive-behavioral stress reduction (CBSR). SUBJECTS: Fifty (50) subjects were recruited from the community and took part in MBSR (n = 36) and CBSR (n = 14) courses. Participants self-selected into MBSR or CBSR courses taught at different times. There were no initial differences between the MBSR and CBSR subjects on demographics, including age, gender, education, and income. INTERVENTION: MBSR was an 8-week course using meditation, gentle yoga, and body scanning exercises to increase mindfulness. CBSR was an 8-week course using cognitive and behavioral techniques to change thinking and reduce distress. DESIGN: Perceived stress, depression, psychological well-being, neuroticism, binge eating, energy, pain, and mindfulness were assessed before and after each course. Pre-post scores for each intervention were compared by using paired t tests. Pre-post scores across interventions were compared by using a general linear model with repeated measures. SETTINGS/LOCATIONS: Weekly meetings for both courses were held in a large room on a university medical center campus. RESULTS: MBSR subjects improved on all eight outcomes, with all of the differences being significant. CBSR subjects improved on six of eight outcomes, with significant improvements on well-being, perceived stress, and depression. Multivariate analyses showed that the MBSR subjects had better outcomes across all variables, when compared with the CBSR subjects. Univariate analyses showed that MBSR subjects had better outcomes with regard to mindfulness, energy, pain, and a trend for binge eating. CONCLUSIONS: While MBSR and CBSR may both be effective in reducing perceived stress and depression, MBSR may be more effective in increasing mindfulness and energy and reducing pain. Future studies should continue to examine the differential effects of cognitive behavioral and mindfulness-based interventions and attempt to explain the reasons for the differences.
