Risky business in Georgia's wild birds: contact rates between wild birds and backyard chickens is influenced by supplemental feed.

Backyard chickens are increasingly popular, and their husbandry varies widely. How backyard chickens are housed may influence the accessibility of chicken feed and water to wild birds, and thus, the contact rates between both groups. Increased contacts have implications for pathogen transmission; for instance, Newcastle disease virus or avian influenza virus may be transmitted to and from backyard chickens from contaminated water or feed. Given this potentially increased pathogen risk to wild birds and backyard chickens, we examined which wild bird species are likely to encounter backyard chickens and their resources. We performed a supplemental feeding experiment followed by observations at three sites associated with backyard chickens in North Georgia, USA. At each site, we identified the species of wild birds that: (a) shared habitat with the chickens, (b) had a higher frequency of detection relative to other species and (c) encountered the coops. We identified 14 wild bird species that entered the coops to consume supplemental feed and were considered high-risk for pathogen transmission. Our results provide evidence that contact between wild birds and backyard chickens is frequent and more common than previously believed, which has crucial epidemiological implications for wildlife managers and backyard chicken owners.

Post COVID-19 Pandemic Increased Detection of Mycoplasma Pneumoniae in Adults Admitted to the Intensive Care.

Background: Mycoplasma pneumoniae (M. pneumoniae) infections can progress to severe respiratory complications, necessitating intensive care treatment. Recent post COVID-19 pandemic surges underscore the need for timely diagnosis, given potential diagnostic method limitations. Methods: A retrospective case series analysis was conducted on M. pneumonia PCR-positive patients admitted to two Dutch secondary hospitals' ICUs between January 2023 and February 2024. Clinical presentations, treatments, outcomes, and mechanical ventilation data were assessed. Results: Seventeen ICU-admitted patients were identified, with a median age of 44 years, primarily due to hypoxia. Non-invasive ventilation was effective for most, while five required invasive mechanical ventilation. None of the patients required extracorporeal membrane oxygenation. No fatalities occurred. Post-PCR, treatment was adjusted to doxycycline or azithromycin; seven received steroid treatment. Discussion: Increased ICU admissions for M. pneumoniae infection were observed. Diverse clinical and radiological findings emphasize heightened clinical awareness. Early molecular diagnostics and tailored antibiotic regimens are crucial since beta-lactam antibiotics are ineffective. Conclusion: This study highlights the escalating challenge of severe M. pneumoniae infections in ICUs, necessitating a multifaceted approach involving accurate diagnostics, vigilant monitoring, and adaptable treatment strategies for optimal patient outcomes.

Prospective assessment of survival, morbidity, and cost associated with lymphadenectomy in low-risk endometrial cancer.

OBJECTIVE: Since 1999, patients with low risk endometrial cancer (EC) as defined by the Mayo criteria have preferably not undergone lymphadenectomy (LND) at our institution. Here we prospectively assess survival, sites of recurrence, morbidity, and cost in this low risk cohort. METHODS: Cause-specific survival (CSS) was estimated using the Kaplan-Meier method and compared using the log-rank test. Complications were graded per the Accordion Classification. Thirty-day cost analyses were expressed in 2010 Medicare dollars. RESULTS: Among 1393 consecutive surgically managed cases, 385 (27.6%) met inclusion criteria, accounting for 34.1% of type I EC. There were 80 LND and 305 non-LND cases. Complications in the first 30 days were significantly more common in the LND cohort (37.5% vs. 19.3%; P<0.001). The prevalence of lymph node metastasis was 0.3% (1/385). Over a median follow-up of 5.4 years only 5 of 31 deaths were due to disease. The 5-year CSS in LND and non-LND cases was 97.3% and 99.0%, respectively (P=0.32). None of the 11 total recurrences occurred in the pelvic or para-aortic nodal areas. Median 30-day cost of care was $15,678 for LND cases compared to $11,028 for non-LND cases (P<0.001). The estimated cost per up-staged low-risk case was $327,866 to $439,990, adding an additional $1,418,189 if all 305 non-LND cases had undergone LND. CONCLUSION: Lymphadenectomy dramatically increases morbidity and cost of care without discernible benefits in low-risk EC as defined by the Mayo criteria. In these low-risk patients, hysterectomy with salpingo-oophorectomy alone is appropriate surgical management and should be standard of care.

[Measurement of patient preferences in ambulatory health-care centres (MVZ)--a comparison of quality of treatment between MVZ and family general practitioners]. / Präferenzmessung von Patienten in medizinischen Versorgungszentren (MVZ) - eine Gegenüberstellung der Behandlungsqualität von MVZ und niedergelassenen Haus- und Fachärzten.

OBJECTIVE: The measurement of patient preferences on the basis of perceived quality of care in a comparison of two ambulatory health-care centres (medizinisches Versorgungszentrum, MVZ) with traditional ambulatory care consisting of single ambulatory practices was undertaken. The influence of the patients' perceived quality of care on patients' preference for an MVZ or traditional ambulatory care setting was analysed. Determinants of the patients' preference were identified. METHODS: 310 questionnaires were distributed to patients in 2 MVZ. The preference measurement is derived from a comparison of 17 quality items in MVZ and traditional ambulatory care settings. Quality items were derived from the literature. The developed research instrument consists of 17 items on a 7-point Likert scale (1=much better to 7=much worse). T-Tests were used to test if the quality of care in MVZ was rated significantly differently in comparison to traditional ambulatory care. The determinants of the patients' preference were identified using a stepwise multiple regression analysis. RESULTS: 310 questionnaires were handed out and the response rate was 92.3% (n=286). 15 out of 17 quality items were rated in favour of the MVZ. Determinants of the patients' preference were the following (n=286, corrected R (2)=0.29): (1) time doctors take for the patient's treatment, (2) medical competence of doctors, (3) counselling regarding preventive examinations (p<0.01). CONCLUSIONS: The judgment in favour of the ambulatory health-care centres (MVZ) could be explained by organisational structures typical of these centres, e. g., the increased information sharing and cooperation amongst doctors. The identified determinants of the patients' "preference" indicate a practical approach for attaining a preference position in the health market, both for medical care centres as well as for single medical practices.

Burn scar contracture release surgery effectively improves functional range of motion, disability and quality of life: A pre/post cohort study with long-term follow-up in a Low- and Middle-Income Country.

OBJECTIVE: Burn scar contractures limit range of motion (ROM) of joints and have substantial impact on disability and the quality of life (QoL) of patients, particularly in a Low- and Middle-Income Country (LMIC) setting. Studies on the long-term outcome are lacking globally; this study describes the long-term impact of contracture release surgery performed in an LMIC. METHODS: This is a pre-post cohort study, conducted in a referral hospital in Tanzania. Patients who underwent burn scar contracture release surgery in 2017-2018 were eligible. ROM (goniometry), disability (WHODAS 2.0) and QoL (EQ-5D) were assessed. The ROM data were compared to the ROM that is required to perform activities of daily living without compensation, i.e. functional ROM. Assessments were performed preoperatively and at 1, 3, 6 and 12 months postoperatively. RESULTS: In total, 44 patients underwent surgery on 115 affected joints. At 12 months, the follow-up rate was 86%. The mean preoperative ROM was 37.3% of functional ROM (SD 31.2). This improved up to 108.7% at 12 months postoperatively (SD 42.0, p < 0.001). Disability-free survival improved from 55% preoperatively to 97% at 12 months (p < 0.001) postoperatively. QoL improved from 0.69 preoperatively, to 0.93 (max 1.0) at 12 months postoperatively (p < 0.001). Patients who regained functional ROM in all affected joints reported significantly less disability (p < 0.001) and higher QoL (p < 0.001) compared to patients without functional ROM. CONCLUSIONS: Contracture release surgery performed in an LMIC significantly improved functional ROM, disability and QoL. Results showed that regaining a functional joint is associated with less disability and higher QoL.

Viral infectivity and intracellular distribution of matrix (M) protein of canine distemper virus are affected by actin filaments.

To investigate the role of cytoskeletal components in canine distemper virus (CDV) replication, various agents were used that interfere with turnover of actin filaments and microtubules. Only inhibition of actin filaments significantly reduced viral infectivity. Analysis of the intracellular localization of the viral matrix (M) protein revealed that it aligned along actin filaments. Treatment with actin filament-disrupting drugs led to a marked intracellular redistribution of M protein during infection as well as transfection. In contrast, the localization of the CDV fusion (F) protein was not significantly changed during transfection. Thus, a M protein-actin filament interaction appears to be important for generation of infectious CDV.

York river destratification: an estuary-subestuary interaction.

Destratification in the York River during high spring tides is the result of the interruption of normal two-layer estuarine flow by the advection of relatively fresh water into the river mouth from the Chesapeake Bay. This advection is due to the presence of a longitudinal salinity gradient in the bay and a difference in the tidal current phase between the river and the bay. Similar behavior is seen in other subestuaries of the Chesapeake Bay and may be common in subestuary-estuary interactions.

Pleural Enterococcus faecalis empyema: an unusual case.

A 63-year-old female patient was admitted to the department of neurology following an acute ischemic infarction of the right medial cerebral artery. She developed fever, respiratory failure, and hypotension and had to be transferred to the intensive care unit (ICU) for intubation and mechanical ventilation. Chest X-ray showed increased density of the complete right hemi-thorax, indicative of massive pleural effusion. Chest tube drainage produced 1.5 l of pus in 1 h. Cultures revealed growth of Enterococcus faecalis. The patient was treated with amoxicillin and clavulanic acid with good clinical response. Enterococci very rarely cause spontaneous pleural empyema. The natural resistance of enterococci to several types of antibiotics can lead to selection of enterococci as seen in other clinical studies and may lead to this unusual clinical consequence.

Border disease virus (BDV) infections of small ruminants in Turkey: a new BDV subgroup?

Blood samples from sheep and/or goats from eight small ruminant flocks in the Turkish provinces of Aydin and Burdur were tested for the presence of Pestiviruses using an antigen-capture ELISA. From clinically affected animals, pathological and immunohistochemical findings were recorded. Post mortem examination of a virus-positive lamb showing abnormal fleece and paralysis of the hind legs revealed nonsuppurative meningoencephalomyelitis with hypomyelinogenesis. By immunohistochemistry Pestivirus antigen was detected in all parts of the brain including cerebellum, cerebral hemispheres and midbrain. Two Pestivirus isolates from a sheep and a goat kid, respectively, were isolated from samples that were positive in the antigen-capture ELISA. Genetic typing using the 5'-NTR (288bp) and N(pro) (738bp) showed that both were Border disease virus (BDV) isolates. By phylogenetic analysis, they formed a cluster clearly separated from the known clusters BDV-1 to BDV-6 and might therefore represent a new subgroup (BDV-7?). This is the first report confirming the occurrence and partial characterisation of BDV infection in small ruminants in Turkey.

Clinical validation of the non-invasive cardiac output monitor USCOM-1A in critically ill patients.

BACKGROUND AND OBJECTIVE: Cardiac output is frequently monitored to maintain and improve cardiac function with the primary goal of adequate tissue perfusion. The pulmonary artery catheter is considered to be the gold standard although several non-invasive devices are being introduced and gaining attention. To evaluate the accuracy of the ultrasonic cardiac output monitor (USCOM)-1A (Pty Ltd, Coffs Harbour, NSW, Australia), a non-invasive cardiac output device including its capability to differentiate between different shock states in haemodynamically unstable ICU patients was used in this single-centre, prospective, observational study. METHODS: Cardiac output was measured with a pulmonary artery catheter and transcutaneously via a suprasternal approach with the USCOM-1A by continuous-wave Doppler ultrasound in 25 adult patients in a mixed medical and surgical ICU in a major teaching hospital in the Netherlands. RESULTS: A total of 1315 USCOM-1A cardiac output measurements were performed. In order to reduce time-variability, the mean of five consecutive USCOM-1A measurements was calculated. Total 263 values were compared with 263 thermodilution cardiac output measurements performed with a pulmonary artery catheter. Data were analysed for systematic error, precision and correlation. Systematic and random errors were found. On average USCOM-1A values were 12% lower than thermodilution measurements (systematic error), while the random error was 17% (coefficient of variation). The error comprised an inter-operator variability of 3%, an inter-patient variability of 11% and residual variability of 15%. The correlation coefficient of the calculated cardiac index with the USCOM-1A and the pulmonary artery catheter was r = 0.8024 and 0.6438, respectively. Temperature and gender did not influence correlations. The learning curve for USCOM-1A skill acquisition was steep. CONCLUSIONS: The correlation between the two techniques was acceptable, although relevant systematic and variable errors were detected. USCOM-1A provided adequate data to distinguish non-invasively different shock types in ICU patients.

Healthcare-related costs in very elderly intensive care patients.

INTRODUCTION: The long-term outcome of "very old intensive care unit patients" (VOPs; ≥ 80 years) is often disappointing. Little is known about the healthcare costs of these VOPs in comparison to younger ICU patients and the very elderly in the general population not admitted to the ICU. METHODS: Data from a national health insurance claims database and a national quality registry for ICUs were combined. Costs of VOPs admitted to the ICU in 2013 were compared with costs of younger ICU patients (two groups, respectively 18-65 and 65-80 years old) and a matched control group of very elderly subjects who were not admitted to the ICU. We compared median costs and median costs per day alive in the year before ICU admission (2012), the year of ICU admission (2013) and the year after ICU admission (2014). RESULTS: A total of 9272 VOPs were included and compared to three equally sized study groups. Median costs for VOPs in 2012, 2013 and 2014 (€5944, €35,653 and €12,565) are higher compared to the ICU 18-65 population (€3022, €30,223 and €5052, all p < 0.001) and the very elderly control population (€3590, €4238 and €4723, all p < 0.001). Compared to the ICU 65-80 population, costs of VOPs are higher in the year before and after ICU admission (€4323 and €6750, both p < 0.001), but not in the year of ICU admission (€34,448, p = 0.950). The median healthcare costs per day alive in the year before, the year of and the year after ICU admission are all higher for VOPs than for the other groups (p < 0.001). CONCLUSIONS: VOPs required more healthcare resources in the year before, the year of and the year after ICU admission compared to younger ICU patients and the very elderly control population, except compared to the ICU 65-80 population in the year of ICU admission. Healthcare costs per day alive, however, are substantially higher for VOPs than for all other study groups in all three studied years.

Correlation between urine ketones (acetoacetate) and capillary blood ketones (3-beta-hydroxybutyrate) in hyperglycaemic patients.

AIMS: To facilitate the transition from urine ketones (acetoacetate) to capillary blood ketones (3-beta-hydroxybutyrate), we studied the correlation between these two tests. METHODS: Retrospective study of all patients with blood glucose greater than or equal to 2.5 g/l on arrival in the Emergency Department. We studied the correlation between urine ketones (Clinitek 50, Bayer) and capillary blood ketones (Optium, Abbott). We then compared the relative risks (RR) of ketoacidosis and hospitalization associated with each of these tests. RESULTS: In 33 months, 529 adult patients with both urine and blood testing for ketones were enrolled (ketoacidosis 8%, admission rate 49%). Urine ketones scored as +, ++ and +++ corresponded to median capillary blood ketone levels of 0.5 mmol/l (IQR: 0.1-0.9), 0.7 mmol/l (IQR: 0.2-1.8) and 3 mmol/l (IQR: 1.4-5.2), respectively. RRs of ketoacidosis or hospitalization associated with blood ketones greater than or equal to 3 mmol/l were higher than those associated with +++ urine ketones: 74 (95% confidence interval [CI]: 48-88) and 2.9 (95% CI: 2.5-3) versus 31 (95% CI: 18-45) and 2 (95% CI: 1.7-2.1), respectively. CONCLUSIONS: In hyperglycaemic patients in the Emergency Department, a good correlation was observed between urine ketones and capillary blood ketones for low values, but a poor correlation was observed for high values. Either test can therefore be used to exclude ketosis, but the capillary blood ketones test is more accurate to confirm ketoacidosis.

Borreliosis: a rare and alternative diagnosis in travellers' febrile illness.

We report a case of borreliosis mimicking uncomplicated malaria in a patient returning from Mali. Identification of spirochetes through examination of a thick blood smear completed by an acridine-orange quantitative buffy coat allowed the diagnosis of borreliosis. All symptoms rapidly resolved following tetracycline therapy. Epidemiological and clinical features of borreliosis, diagnostic tools and management are discussed.

[Familial occurrence of a congenital defect of the keratinisation of the skin in German Angus calves]. / Familiäres Auftreten einer angeborenen Verhornungsstörung der Haut bei zwei Kälbern der Rasse Deutsche Angus.

Congenital dysfunction of the keratinisation of the epithelium was diagnosed in two female German Angus calves born on the same farm. The relationship coefficient between the two affected Angus calves was 34.38%. The clinical findings were similar to ichthyosis congenita as the alterations of the skin were present at birth and the levels of zinc in the blood were not decreased. However, parakeratosis could not be completely excluded as skin alterations were partly parakeratotic. On account of the close relationship between the two affected calves a genetic cause is likely for the present cases.

Severe neurological symptoms following synthetic cannabinoid intoxication.

Synthetic cannabinoids are becoming increasingly popular as substances of abuse. However, in the Netherlands synthetic cannabinoid intoxications are rare. We report a 16-year-old male who became deeply comatose and was admitted to the intensive care unit for invasive mechanical ventilation after a buse of aninitially unknown drug. Routine toxicology screening with an immunoassay only detected tetrahydrocannabinol, but additional tests with liquid chromatography mass spectrometry revealed synthetic cannabinoid use. This case underlines the challenging diagnosis of synthetic cannabinoid intoxications and the severe complications they can produce.

'Nutrothorax' due to misplacement of a nasogastric feeding tube.

we report a serious complication of blind nasogastric feeding tube insertion in a 65-year-old female patient, which was overlooked and caused severe respiratory failure.
