Agricultural run-off in Australia's Mackay-Whitsunday region is a major source of nutrient and pesticide pollution to coastal and inshore ecosystems of the Great Barrier Reef. While the effects of run-off are well documented for the region's coral and seagrass habitats, the ecological impacts on estuaries, the direct recipients of run-off, are less known. This is particularly true for fish communities, which are shaped by the physico-chemical properties of coastal waterways that vary greatly in tropical regions...

BACKGROUND: The Near Visual Acuity Questionnaire Presbyopia (NAVQ-P) is a patient-reported outcome (PRO) measure that was developed in a phakic presbyopia population to assess near vision function impacts. The study refined and explored the psychometric properties and score interpretability of the NAVQ-P and additional PRO items assessing near vision correction independence (NVCI), near vision satisfaction (NVS), and near vision correction preference (NVCP). METHODS: This was a psychometric validation study conducted using PRO data collected as part of a Phase IIb clinical trial (CUN8R44 A2202) consisting of 235 randomized adults with presbyopia from the US, Japan, Australia, and Canada...

Ramalina farinacea is a widely distributed epiphytic lichen from the Macaronesian archipelagos to Mediterranean and Boreal Europe. Previous studies have indicated a specific association between R. farinacea and Trebouxia microalgae species. Here, we examined the symbiotic interactions in this lichen and its closest allies (the so-called " R. farinacea group") across ten biogeographic subregions, spanning diverse macroclimates, analyzing the climatic niche of the primary phycobionts, and discussing the specificity of these associations across the studied area...

Studies on the impact of the COVID-19 pandemic in sub-Saharan Africa have yielded varying results, although authors universally agree the real burden surpasses reported cases. The primary objective of this study was to determine SARS-CoV-2 seroprevalence among patients attending Monkole Hospital in Kinshasa (D.R. Congo). The secondary objective was to evaluate the analytic performance of two chemiluminescence platforms: Elecsys® (Roche) and VirClia® (Vircell) on dried blood spot samples (DBS). The study population (N = 373) was recruited in two stages: a mid-2021 blood donor cohort (15...

The plastic production that contributes to the global plastic reservoir presents a major challenge for society in managing plastic waste and mitigating the environmental damage of microplastic (MP) pollution. In the environment, the formation of biomolecular corona around MPs enhance the stability of MP suspensions, influencing the bioavailability and toxicity of MPs. Essential physical properties including MP stability, dispersibility, agglomeration, and dimensional size must be precisely defined and measured in complex media taking into account the formation of a protein corona...

BACKGROUND: Currently, a lively debate exists within the scientific community regarding the most suitable procedure for treating stages IIIB-IVB carcinoma of the ovary, fallopian tubes, and peritoneum. The options under most consideration are primary cytoreductive surgery or neoadjuvant chemotherapy followed by interval cytoreductive surgery. PRIMARY OBJECTIVE: To compare overall survival at 5 years in patients who underwent primary cytoreductive surgery versus neoadjuvant chemotherapy and interval cytoreductive surgery for stage IIIB-IVB ovarian cancer STUDY HYPOTHESIS: The treatment with primary cytoreductive surgery results in superior patient survival compared with neoadjuvant chemotherapy followed by interval cytoreductive surgery...

This review article delves into the historical journey of bowel surgery, its contemporary importance in cytoreductive procedures for gynecologic cancers, and the general principles of digestive surgery. From pioneering surgeons such as Lane, Broca, and Billroth to the introduction of mechanical staplers, this narrative unfolds the remarkable advances in the field...

Uterine carcinosarcoma is a rare high-grade endometrial cancer. Controversy has surrounded a number of aspects in the diagnosis and management of this unique clinicopathological entity, including the efficacy of adjuvant therapy, which has been questioned. An unusual surgico-pathological parameter with prognostic significance in a number of tumour sites is the lymph node ratio (LNR). The availability of data in this respect has been scarce in the literature. The primary aim of this collaborative study was to evaluate the prognostic value of LNR in patients with uterine carcinosarcoma...

OBJECTIVE: Between 20% and 30% of women who have undergone tubal ligation regret their decision. The alternative to regain fertility for these women is either in vitro fertilization or tubal re-anastomosis. This article presents a systematic review with meta-analysis to assess the current evidence on the efficacy of tubal recanalization surgery in patients who have previously undergone tubal ligation. STUDY DESIGN: The search was conducted in the World of Science (WOS) database, The Cochrane Library and ClinicalTrials...

Postpartum haemorrhage (PPH) is a significant cause of maternal mortality globally, necessitating prompt and efficient management. This review provides a comprehensive exploration of endovascular treatment dimensions for both primary and secondary PPH, with a focus on uterine atony, trauma, placenta accreta spectrum (PAS), and retained products of conception (RPOC). Primary PPH, occurring within 24 h, often results from uterine atony in 70% of causes, but also from trauma, or PAS. Uterine atony involves inadequate myometrial contraction, addressed through uterine massage, oxytocin, and, if needed, mechanical modalities like balloon tamponade...

The European Society of Gynaecological Oncology, the European Society for Medical Oncology (ESMO) and the European Society of Pathology held a consensus conference (CC) on ovarian cancer on 15-16 June 2022 in Valencia, Spain. The CC panel included 44 experts in the management of ovarian cancer and pathology, an ESMO scientific advisor and a methodologist. The aim was to discuss new or contentious topics and develop recommendations to improve and harmonise the management of patients with ovarian cancer. Eighteen questions were identified for discussion under four main topics: (i) pathology and molecular biology, (ii) early-stage disease and pelvic mass in pregnancy, (iii) advanced stage (including older/frail patients) and (iv) recurrent disease...

BACKGROUND: The Adolescents and Adults Living with Perinatal HIV (AALPHI) study is one of only three cohort studies worldwide evaluating the impact of HIV on young people living with perinatal HIV (PLHIV) relative to a comparable group of HIV negative young people in close relationship with an HIV positive individual, for example, their mother, sibling or partner. This project aimed to engage young people with the AALPHI study findings, help them take ownership, and decide how they would disseminate the key messages to both study participants and to the wider community...

BACKGROUND: Sparing the Great Saphenous Vein capital for possible arterial substitution and recurrence decrease may be an alternative to current ablation options for Varicose Veins treatment. Conservative surgery of varicose veins (CHIVA) was suggested in 1988 by Franceschi, by limited veins interruptions in strategic points. However, the method did not diffuse due to the need for high Duplex expertise to determine the procedure in every single patient. METHOD: Evaluation of the literature regarding saphenous sparing, with special reference to CHIVA...

The etiology of the venous insufficiency of the lower limbs is related to the increase of the district pressure. This occurs in case of pressure overload of the afferent compartment with a progressive increase of the gradient until the reversal of the flow direction. Varicose veins would be the effect and not the cause of the pressure overload which must always be researched in the efferent (draining) compartment. The gradient inversion in a compartment causes a reflux circuit (venous shunt) only if - in addition to the escape point - one re-entry point is also active, The closure of the escape point does not solve the etiological moment of the district pressure overload...
