Labor Stress and Nursing Support: How do They Relate?

Selected aspects of the phenomenon of labor stress including the relationship between labor stress and nursing support were explored using a correlational design with 85 postpartum women who delivered vaginally and were recruited from a Midwestern general hospital in the United States. The Wijma Delivery Expectancy/Experience Questionnaire measured labor stress while the Bryanton Adaptation of the Nursing Support in Labor Questionnaire measured nursing support during labor. Significant positive correlations were found between number of labor hours and labor stress (r = .25, p = .020) and number of labor hours and number of labor procedures (r = .23, p = .031). A significant negative correlation (r = - .36, p \u3c .01) between labor stress and nursing support was found. Data from this study confirmed previous findings regarding nursing support and emphasized the important role that nursing support plays in alleviating labor stress

An exploratory study of dog park visits as a risk factor for exposure to drug-resistant extra-intestinal pathogenic E. coli (ExPEC).

Background Extraintestinal pathogenic E. coli (ExPEC) are common causative agents of urinary tract infections in humans. Dogs have been found to harbor ExPEC. This study tested stool samples from dogs (n = 16), the shoes of dog park visitors (n = 16) and the shoes of controls (n = 16) for ExPEC. Phenotypic resistance of isolates was characterized. Findings ExPEC were present in one-third of the dog stool samples, 9% of the samples from the shoes of dog park visitors and 6% of control samples. Half of the ExPEC isolates were multi-drug resistant. Discussion The findings suggest that dogs may be an important source of antibiotic resistant ExPEC

Psychology students’ perception of and engagement with feedback as a function of year of study

Undergraduate students’ perception of feedback and level of engagement with the feedback they receive have gained increasing attention in the educational literature recently to identify areas which require educators’ attention. However, research in this area has generally been based on limited self-selecting samples, and has not considered how students’ relationship with feedback may alter depending on their year of study. To address this, a survey measuring students’ views and practices regarding feedback was completed at a higher education institution by 447 first-, second- and third-year psychology students, representing 77% of the cohort. Findings revealed that third years responded more negatively in both areas than their first- and second-year counterparts, whose ratings on these aspects themselves were far from optimal. These findings highlight the need for early interventions to improve students’ perception of and engagement with feedback in the earlier years, and to prevent the recorded deterioration later on in the degree course

Chronic nonpuerperal uterine inversion and necrosis: a case report

<p>Abstract</p> <p><b>Introduction</b></p> <p>Inversion of the non-pregnant uterus is rare.</p> <p><b>Case presentation</b></p> <p>A 56-year-old African American woman presented to our emergency center with complaints of a mass protruding from her vagina. She subsequently underwent vaginal myomectomy, abdominal hysterectomy and bilateral salpingo-oophorectomy. Pathologic examination revealed a necrotic fibroid and endometrium. At the time of laparotomy an inverted uterus was diagnosed when a 3 cm dimple containing bilateral round ligaments, infundibulopelvic ligaments and bladder was observed.</p> <p>Conclusion</p> <p>Chronic nonpuerperal inversion of the uterus is rare. Infection should be suspected and appropriate broad spectrum antibiotics begun while planning surgery. An attempt at vaginal restoration and removal is difficult. Abdominal hysterectomy may be necessary taking care to locate the distal urinary collecting system.</p

Cross-shell excitations in Si 31

The Si31 nucleus was produced through the O18(O18, αn) fusion-evaporation reaction at Elab=24MeV. Evaporated α particles from the reaction were detected and identified in the Microball detector array for channel selection. Multiple γ-ray coincidence events were detected in Gammasphere. The energy and angle information for the α particles was used to determine the Si31 recoil kinematics on an event-by-event basis for a more accurate Doppler correction. A total of 22 new states and 52 new γ transitions were observed, including 14 from states above the neutron separation energy. The positive-parity states predicted by the shell-model calculations in the sd model space agree well with experiment. The negative-parity states were compared with shell-model calculations in the psdpf model space with some variations in the N=20 shell gap. The best agreement was found with a shell gap intermediate between that originally used for A≈20 nuclei and that previously adapted for P32,34. This variation suggests the need for a more universal cross-shell interaction

Measurement report : Atmospheric new particle formation in a coastal agricultural site explained with binPMF analysis of nitrate CI-APi-TOF spectra

The occurrence of new particle formation (NPF) events detected in a coastal agricultural site, at Qvidja, in Southwestern Finland, was investigated using the data measured with a nitrate ion-based chemicalionization atmospheric-pressure-interface time-of-flight (CI-APi-TOF) mass spectrometer. The binned positive matrix factorization method (binPMF) was applied to the measured spectra. It resulted in eight factors describing the time series of ambient gas and cluster composition at Qvidja during spring 2019. The most interesting factors related to the observed NPF events were the two factors with the highest mass-to-charge ratios, numbered 7 and 8, both having profiles with patterns of highly oxygenated organic molecules with one nitrogen atom. It was observed that factor 7 had elevated intensities during the NPF events. A variable with an even better connection to the observed NPF events is f(F7), which denotes the fraction of the total spectra within the studied mass-to-charge ratio range between 169 and 450Th being in a form of factor 7. Values of f(F7) higher than 0.50 +/- 0.05 were observed during the NPF events, of which durations also correlated with the duration of f(F7) exceeding this critical value. It was also observed that factor 8 acts like a precursor for factor 7 with solar radiation and that the formation of factor 8 is associated with ozone levels.Peer reviewe

Outcomes in culture positive and culture negative ascitic fluid infection in patients with viral cirrhosis: cohort study

<p>Abstract</p> <p>Background</p> <p>Ascitic fluid infection (AFI) in cirrhotic patients has a high morbidity and mortality. It has two variants namely, spontaneous bacterial peritonitis (SBP) and culture negative neutrocytic ascites (CNNA). The aim of this study was to determine the outcome in cirrhotic patients with culture positive (SBP) and culture negative neutrocytic ascites.</p> <p>Methods</p> <p>We analyzed 675 consecutive hepatitis B and/or C related cirrhosis patients with ascites admitted in our hospital from November 2005 to December 2007. Of these, 187 patients had AFI; clinical and laboratory parameters of these patients including causes of cirrhosis, Child Turcotte Pugh (CTP) score were recorded.</p> <p>Results</p> <p>Out of 187 patients with AFI, 44 (23.5%) had SBP while 143 (76.4%) had CNNA. Hepatitis C virus (HCV) infection was the most common cause of cirrhosis in 139 (74.3%) patients. Patients with SBP had high CTP score as compared to CNNA (12.52 ± 1.45 vs. 11.44 ± 1.66); p < 0.001. Platelets count was low in patients with SBP (101 ± 53 × 10⁹/L) as compared to CNNA (132 ± 91 × 10⁹/L), p = 0.005. We found a high creatinine (mg/dl) (1.95 ± 1.0 vs. 1.44 ± 0.85), (p = 0.003) and high prothrombin time (PT) in seconds (24.8 ± 6.6 vs. 22.4 ± 7.2) (p = 0.04) in SBP as compared to CNNA. More patients with SBP (14/44; 31.8%) had blood culture positivity as compare to CNNA (14/143; 9.8%), p = 0.002. Escherichia. Coli was the commonest organism in blood culture in 15/28 (53.5%) patients. SBP group had a higher mortality (11/44; 25%) as compared to CNNA (12/143; 8.4%), p = 0.003. On multiple logistic regression analysis, creatinine >1.1 mg/dl and positive blood culture were the independent predictors of mortality in patients with SBP.</p> <p>Conclusion</p> <p>Patients with SBP have a higher mortality than CNNA. Independent predictors of mortality in SBP are raised serum creatinine and a positive blood culture.</p
