Removal of dietary proteins and oils on salmon performance
Atlantic salmon post-smolts of an average of 940g were fed six diets including two marine-based commercial diets one with partial inclusion of vegetable proteins (VPs) and oils (VOs) (2011/12 EU standards) (MB) and a second with partial inclusion of VPs, land animal-by-product (ABP) proteins and VOs (non-EU standards) (MBABP), a fully vegetable protein (VP) diet; a fully algal and VOs (VO) diet; a fishery-free vegetable-based (VP/VO) diet; and a fishery-free diet with a mix of VPs and ABP proteins and a mix of algal and vegetable oils (MFABP). Growth was assessed at Days 104 and 175, whereas fillet proximate composition, haematology and innate immune responses were assessed upon termination. Overall, MB salmon was the best performing group for the full period in terms of feed intake and overall weight gain. MB and VP salmon exhibited the highest FCRs compared to the other groups, while VP salmon exhibited the highest condition factor (K) and VO salmon the lowestKcompared to the other groups. Fillet proximate composition did not present differences among the six groups. MB salmon demonstrated the highest plasma lysozyme activity compared to the other groups while MFABP, VP and VP/VO salmon demonstrated higher plasma anti-protease activity in contrast to MB salmon. The dietary groups did not present differences in plasma protein, total IgM or natural haemolytic activity while unaltered head kidney macrophage respiratory burst activity was also observed. Overall, diets free from marine proteins or oils and/or both were satisfactorily utilized by salmon without compromising their immune capacity, although longer adaptation periods are required
Comparison of minimally invasive surgical approaches for hysterectomy at a community hospital: robotic-assisted laparoscopic hysterectomy, laparoscopic-assisted vaginal hysterectomy and laparoscopic supracervical hysterectomy
The study reported here compares outcomes of three approaches to minimally invasive hysterectomy for benign indications, namely, robotic-assisted laparoscopic (RALH), laparoscopic-assisted vaginal (LAVH) and laparoscopic supracervical (LSH) hysterectomy. The total patient cohort comprised the first 237 patients undergoing robotic surgeries at our hospital between August 2007 and June 2009; the last 100 patients undergoing LAVH by the same surgeons between July 2006 and February 2008 and 165 patients undergoing LAVHs performed by nine surgeons between January 2008 and June 2009; 87 patients undergoing LSH by the same nine surgeons between January 2008 and June 2009. Among the RALH patients were cases of greater complexity: (1) higher prevalence of prior abdominopelvic surgery than that found among LAVH patients; (2) an increased number of procedures for endometriosis and pelvic reconstruction. Uterine weights also were greater in RALH patients [207.4 vs. 149.6 (LAVH; P < 0.001) and 141.1 g (LSH; P = 0.005)]. Despite case complexity, operative time was significantly lower in RALH than in LAVH (89.9 vs. 124.8 min, P < 0.001) and similar to that in LSH (89.6 min). Estimated blood loss was greater in LAVH (167.9 ml) than in RALH (59.0 ml, P < 0.001) or LSH (65.7 ml, P < 0.001). Length of hospital stay was shorter for RALH than for LAVH or LSH. Conversion and complication rates were low and similar across procedures. Multivariable regression indicated that LAVH, obesity, uterine weight â„250 g and older age predicted significantly longer operative time. The learning curve for RALH demonstrated improved operative time over the case series. Our findings show the benefits of RALH over LAVH. Outcomes in RALH can be as good as or better than those in LSH, suggesting the latter should be the choice primarily for women desiring cervix-sparing surgery
The Influence of Aetiology of Hip Instability on the Results of Pelvic Support Osteotomy
Repercussions of overturning Roe v. Wade for women across systems and beyond borders
June 24th, 2022, a day that will be etched in today and future generationsâ textbooks as a historic day, the United States of America revoked the constitutional right to seek safe abortion care. Overturning Roe v Wade allowed the divided individual states to independently decide the legal parameters regarding abortion care. A decision that disproportionately effects the reproductive lives of women residing on the land of America. Given the systemic impacts of racism, neoliberalism and white supremacy, it is the Black, racialized and poor women who suffer terrible repercussions. In this commentary the authors begin by discussing the historical biopolitical perspective, colonial systems and longstanding impacts on racialized womenâs bodies in America. The discussion transitions to the implications of geopolitics at play nationally and cascading impacts globally, focusing on humanitarian and emergency settings. Using a medical humanities perspective, authors highlight the collision between politics and reproductive health policy and its implications on social determinants of health, such as womenâs education, employment, housing, racial and gender equity and wellbeing. Long standing advocates, community leaders and healers, leading scientists, birth attendants, doctors, nurses, allied health professionals/providers and humanitarian workers â and many others - are reminded and live the weight of the continuous battle of population control, stemming from the oppressive history of control and exploitation
Distraction osteogenesis in management of composite bone and soft tissue defects
A soft tissue defect is one of the most difficult problems that may accompany bone defects. Plastic surgery is often required. During distraction osteogenesis, not only the bone but also the soft tissues are lengthened, which may help in spontaneous closure of the soft tissue defects. This study examines 11 cases of composite bone and soft tissue defects which were managed by distraction osteogenesis. After debridement of the necrotic tissues, the soft tissue defects ranged from three by four centimetres to five byâ14Â centimetres and the bone defects ranged from four to 12Â centimetres. All the soft tissue defects healed during the process of bone transport without the need for plastic surgery, except in one case. The complications were successfully managed during the course of treatment. Distraction osteogenesis is a good method for simultaneous treatment of composite bone and soft tissue defects
