The aims of this study were to document the presence and prevalence of feline lipiduria and renal lipid deposition on CT, and to search for associations between the presence of lipiduria and sex, urinary tract abnormalities and urolithiasis.

The CT examinations of 252 cats were reviewed for the presence of an antigravitational hypodense bubble in the urinary bladder with density values between -180 Hounsfield units (HU) and -20 HU. To identify associations between lipiduria and sex, urinary tract abnormalities and urolithiasis, Fisher’s exact test was used. Renal cortical density measurement was performed in all cats. The Mann-Whitney test was performed to compare renal cortical density between lipiduric and unaffected cats.

A total of 27 domestic cats (10.7%) had CT evidence of lipiduria. Lipiduric cats had a significantly lower renal cortical density than unaffected cats (

<0.01). Male neutered cats had a significantly higher frequency of lipiduria and lower renal cortical density compared with female neutered cats (

<0.01). There was no significant difference between the groups regarding renal, ureteral or urethral abnormalities.

Lipiduria is a common physiological phenomenon in cats that can be detected on routine CT examinations. Decreased renal cortical density is associated with lipiduria. This may aid in the diagnosis of feline lipiduria and help to differentiate its presence from other pathological depositions and excretions.

This study investigated the relationship between adult-initiated family violence (i.e., child exposure to intimate partner violence [CEIPV] and child abuse) and adolescent-to-parent violence (APV), with a particular focus on the moderating effect of peer attachment on this relationship. A sample of 709 adolescents from the Children and Adolescent Survey (a subset of the 2010 Nationwide Survey of Domestic Violence in South Korea) was used. The survey included measures of child abuse, CEIPV, APV, peer attachment, and demographic characteristics. Multiple regression analysis was conducted to examine the association between two types of adults-initiated family violence and APV. The interaction terms of peer attachment were included in the regression analysis to test its moderating effect. The results indicate that child abuse victimization is significantly associated with APV, but peer attachment significantly buffers the negative effect of child abuse on APV. CEIPV was not significantly associated with APV. The findings of the current study highlight the importance of breaking cycles of violence and improving children’s relationships with their peers in preventing parent violence. Counselors and social workers should explore APV perpetrators’ child abuse history when conducting interventions. School counseling programs can help reduce adolescents’ violent behaviors towards their parents by promoting positive peer relationships and peer bonding.Objective To evaluate rates of postoperative infection in patients with acute purulent appendicitis or gangrenous perforated appendicitis after laparoscopic appendectomy (LA). Methods In this retrospective cohort study the medical records of patients who had undergone LA for acute appendicitis at Yijishan Hospital of Wannan Medical College between January 2015 and December 2019 were reviewed. The patients were divided into 2 groups based on the sequential order in which peritoneal irrigation, suction, and extraction of appendix had been performed. In Group 1 peritoneal irrigation and suction had been performed before extraction of the appendix, and in Group 2 they had been performed after extraction of the appendix. Demographic details, surgery duration, time to first flatus, length of hospital stay, total hospitalization expenses, and postoperative complications were analyzed. Results The final study sample included 571 patients, 116 (20.3%) in Group 1 and 455 (79.7%) in Group 2. There were no significant differences in demographic characteristics, preoperative white blood cell counts, surgery durations, lengths of hospital stay, or total hospitalization expenses between the 2 groups (P > .05). Time to first flatus was significantly shorter in Group 1 (2.1 ± 0.5 days) than in Group 2 (2.3 ± 0.6) (P = .016), and the incidence of surgical wound infection was lower in Group 1 (6.9%) than in Group 2 (14.1%) (P = .038). There were no significant differences in the rates of intra-abdominal abscess, small bowel obstruction, or readmission within 30 days between the 2 groups (P > .05). Conclusion Patients with acute purulent appendicitis or gangrenous perforated appendicitis are at high risk of surgical wound infection. Peritoneal irrigation and suction before appendix extraction may reduce the incidence of postoperative wound infection.A new nitrous oxide (N2O)-reducing bacterium was isolated from a consortium that was enriched using advanced wastewater treatment sludge as an inoculum and N2O as the sole nitrogen source. The isolated facultative anaerobe was identified as Azospira sp. Piperlongumine datasheet HJ23. Azospira sp. HJ23 exhibited optimum N2O-reducing activity with a C/N ratio of 62 at pH 6 in the temperature range of 37 °C to 40 °C. The optimum carbon source for N2O reduction was a mixture of glucose and acetate. The maximum rate of N2O reduction by Azospira sp. HJ23 was 4.8 mmol·g-dry cell-1·h-1, and its N2O-reducing activity was higher than other known N2O reducers. Azospira sp. HJ23 possessed several functional genes for denitrification. These included narG (NO3- reductase), nirK (NO2- reductase), norB (NO reductase), and nosZ (N2O reductase) genes. These results suggest that Azospira sp. HJ23 can be applied in the denitrification process to minimalize N2O emission.
