[The Influence of Confinement Location on Maternal Psychological and Role Adaptation: A Six-Month Follow-Up Study].

BACKGROUND: Approximately 70% of postpartum women in Taiwan choose postpartum care institutions for their postpartum confinement. However, few studies have explored the follow-up relationship between confinement location and, respectively, maternal psychological and role adaptation. PURPOSE: To explore the differences in psychology and maternal role adaptation between postpartum women in two different confinement locations and to analyze the predictors of maternal confidence and maternal competence at six-months postpartum. METHODS: A comparative and follow-up research design was adopted. We recruited a convenience sample of two groups of women confined, respectively, at postpartum nursing centers and at home. One hundred fifty-seven mothers recruited after G-power estimation were enrolled as participants and completed demographic data and six scales at one-week, one-month, and six-months postpartum. The statistical analysis was performed mainly using generalized estimating equations. RESULTS: For all participants, maternal confidence was positively associated with time, being multipara, having religious beliefs, and having better mother-infant bonding (p < .05). In addition, being confined at home, being unemployed, having religious beliefs, perceiving lower levels of stress and depression, having better sleep quality, and having better mother-infant bonding were associated with higher maternal competence (p < .05). CONCLUSIONS / IMPLICATIONS FOR PRACTICE: Based on the findings of this study, postpartum nursing institutions should actively promote strategies to improve maternal competence to help mothers staying in postpartum nursing centers strike an optimal balance between recuperation and parenting preparation. Furthermore, obstetric health professionals should implement policies related to mother-infant bonding to increase maternal confidence and competence and, subsequently, facilitate maternal role adjustment.

Preliminary study of virtual touch tissue imaging quantification in diffuse testicular diseases of male infertility.

Objective To explore the preliminary application method and diagnostic value of virtual touch tissue imaging quantification (VTIQ) in diffuse testicular diseases of male infertility. A total of 70 male examiners in our hospital from June 2019 to March 2020 were selected as the research objects. According to whether the subjects are sick (testicular microlithiasis, varicocele), all subjects are divided into three groups: normal group, testicular microlithiasis group, and varicocele group. Whether there is a difference between the groups, and analyze whether there is a correlation between the index reflecting the quality of the semen and the testicular shear wave velocity. The measurement of different positions in the testis will affect the magnitude of the shear wave velocity (P < 0.05). The shear wave velocities of the testes of different diseases are obviously different from the normal side. At the same time, postural changes will have a certain impact on the shear wave velocities of both testes (all P < 0.05). There is a certain correlation between the testicular shear wave velocity and the conventional semen quality index (total sperm motility (P < 0.05)) of the subjects. Acoustic palpation tissue imaging quantitative technology can be applied to the diagnosis of male testes and testicular-related diseases (especially diffuse testicular diseases), and is more suitable for male infertility, which can provide clinical diagnosis and treatment options certain imaging basis.

Utilizing Odor-Adsorbed Filter Papers for Detection Canine Training and Off-Site Fire Ant Indications.

The red imported fire ant (RIFA, Solenopsis invicta) is an exotic aggressive pest that is notorious for its ability to seriously harm humans and animals, cause economic loss to agriculture, and damage ecosystems. This is the first study to validate the capability of filter paper adsorption as a feasible odor bearer of RIFAs and evaluate its use in detection dog training. Two live RIFA-experienced detection dogs achieved a mean 92% positive indication rate (PIR) on RIFA-scented papers with a relatively low false response rate (0.8%). The similar accuracies in recognizing live RIFAs (96%) and scented papers (92%) suggest that a filter paper is an effective odor reservoir. After training with live RIFA and scented filter papers, both RIFA-experienced and inexperienced detection dogs successfully indicated filter papers that were scented with at least 10 RIFAs for 4 h with a high PIR (>93%) and low false response rate (2%). Detection dogs correctly recognized the filter papers scented by 10 RIFAs for 24 h with a 97.6% PIR. Even for scented samples stored at -20 °C and 4 °C for 13 weeks, the positive indication rates (PIRs) were as high as 90%. These results suggest that filter paper is an effective RIFA odor bearer, and the scent can be maintained at least 13 weeks for dog identification. After RIFA-scented paper training, detection dogs showed high (>95%) PIRs for both RIFA-scented paper and live RIFAs and also successfully performed field studies. Using filter paper as a RIFA odor bearer is an effective and economical method for detection dog training and RIFA identification.

Fire ant-detecting canines: a complementary method in detecting red imported fire ants.

In this investigation, detection dogs are trained and used in identifying red imported fire ants, Solenopsis invicta Buren, and their nests. The methodology could assist in reducing the frequency and scope of chemical treatments for red imported fire ant management and thus reduce labor costs and chemical use as well as improve control and quarantine efficiency. Three dogs previously trained for customs quarantine were retrained to detect the scents of red imported fire ants. After passing tests involving different numbers of live red imported fire ants and three other ant species--Crematogaster rogenhoferi Mayr, Paratrechina longicornis Latreille, and Pheidole megacephala F.--placed in containers, ajoint field survey for red imported fire ant nests by detection dogs and bait traps was conducted to demonstrate their use as a supplement to conventional detection methods. The most significant findings in this report are (1) with 10 or more red imported fire ants in scent containers, the dogs had >98% chance in tracing the red imported fire ant. Upon the introduction of other ant species, the dogs still achieved on average, a 93% correct red imported fire ant indication rate. Moreover, the dogs demonstrated great competence in pinpointing emerging and smaller red imported fire ant nests in red imported fire ant-infested areas that had been previously confirmed by bait trap stations. (2) Along with the bait trap method, we also discovered that approximately 90% of red imported fire ants foraged within a distance of 14 m away from their nests. The results prove detection dogs to be most effective for red imported fire ant control in areas that have been previously treated with pesticides and therefore containing a low density of remaining red imported fire ant nests. Furthermore, as a complement to other red imported fire ant monitoring methods, this strategy will significantly increase the efficacy of red imported fire ant control in cases of individual mount treatment.
