Identifying effluents from a food processing industry

The agri-food industry in Morocco generates significant volumes of liquid waste, contributing to environmental challenges that directly impact public health. To address this issue, it is crucial to characterize this wastewater comprehensively, enabling the development of suitable treatment strategies to alleviate pollution and potentially facilitate recycling. This study focuses on the identification of effluents from an olive and caper preservation industry, employing physicochemical and bacteriological analyses on raw, decanted, and filtered effluent samples. The findings reveal that the effluent from the olive and caper preservation industry is characterized by high acidity and an exceptionally elevated mineral load. Notably, the application of decantation and filtration methods demonstrates a limited influence, primarily affecting the reduction of suspended solids. Understanding these physicochemical and bacteriological characteristics is pivotal for devising targeted treatment protocols, ensuring effective pollution reduction, and exploring avenues for potential recycling of this agri-food industry wastewater. This research serves as a foundation for informed decision-making in the development of sustainable and efficient wastewater management practices, balancing environmental preservation with industrial needs

What effects does an organic amendment to olive waste have on the soil and crop yield?

Intensive agriculture or phenomena such as pollution, compaction, and/or erosion lead to a decrease in the amounts of organic matter of soils; thus, causing a decrease in their fertility. The use of an organic amendment in agriculture could combat soil degradation. In this sense, two organic amendments with olives waste (OW) and olive mill wastewater (OMW) have been manufactured.  The objective of this work is to examine the capacity of these amendments to improve soil quality in comparison with manure (M). Three types of soil were tested: the first has been amended for two years with a compost of similar composition (S1), the second not amended (S2), and the third corresponds to an agricultural soil that is amended with chemical fertilizer (S3). All the trials were carried out on two vegetable gardens: potato and radish. The ANOVA shows that the amendment effect was highly significant on all the physicochemical parameters studied except humidity. In conclusion, this product could be an alternative to chemical fertilizers and considered as a perennial solution adapted to the context of sustainable development to the recovery of olive waste

Agronomic valorization of the composts with olive waste

In the Mediterranean countries, olive waste, a co-product of the olive oil trituration process, presents a serious environmental problem because of their polyphenol charge, given the quantities rejected each year. In previous works, this waste has been co-composted with other substrates and has been transformed into non-phytotoxic substances in conformity with the French standard NFU44-051 due to their composition in nutritional elements like soluble sugars, proteins and mineral elements. This study examines the efficacy of these substances on radish and potato crops. To do this, seeds were sown on the plot. For each crop, 4 plots were planned: land amended with manure (M), NPK fertilizer (F), the vegetable water substance (VW) and the olive-pomace substance (OP) in addition to the vegetable water. The first three substances served as controls. A statistical study of correlation between the latter and those that characterize the soil after amendment was carried out.  The obtained results showed that there are two strong correlations between pH, organic matter, dry matter and soil moisture amended by the OW compost and, on the one hand, the morphological growth parameters of the two crops and, on the other hand, the parameters of their production

Current Opinion and Practice on Peritoneal Carcinomatosis Management: The North African Perspective.

The status of peritoneal surface malignancy (PSM) management in North Africa is undetermined. The aim of this study was to assess and compare current practice and knowledge regarding PSM and examine satisfaction with available treatment options and need for alternative therapies in North Africa. This is a qualitative study involving specialists participating in PSM management in North Africa. The survey analyzed demographic characteristics and current knowledge and opinions regarding PSM management in different institutions. We also looked at goals and priorities, satisfaction with treatment modalities and heated intraperitoneal chemotherapy (HIPEC) usefulness according to specialty, country, years of experience, and activity sector. One-hundred and three participants responded to the survey (response rate of 57%), including oncologists and surgeons. 59.2% of respondents had more than 10 years experience and 45.6% treated 20-50 PSM cases annually. Participants satisfaction with PSM treatment modalities was mild for gastric cancer (3/10 [IQR 2-3]) and moderate for colorectal (5/10 [IQR 3-5]), ovarian (5/10 [IQR 3-5]), and pseudomyxoma peritonei (5/10 [IQR 3-5]) type of malignancies. Good quality of life and symptom relief were rated as main priorities for treatment and the need for new treatment modalities was rated 9/10 [IQR 8-9]. The perceived usefulness of systemic chemotherapy in first intention was described as high by 42.7 and 39.8% of respondents for PSM of colorectal and gastric origins, while HIPEC was described as highly useful for ovarian (49.5%) and PMP (73.8) malignancies. The management of PSM in the North African region has distinct differences in knowledge, treatments availability and priorities. Disparities are also noted according to specialty, country, years of expertise, and activity sector. The creation of referral structures and PSM networks could be a step forward to standardized PSM management in the region

PLACE DE LA CHIRURGIE DANS LA PRISE EN CHARGE DE LA MALADIE DE CROHN ANO-PERINEALE

Introduction: The attack ano-perinéale during the disease of Crohn is relatively frequent, with difficult treatment. Materials and methods: A retrospective study, spread out over six years, 12 patient collages in the service of visceral and proctologic surgery II of the military hospital of instruction Mohamed V of Rabat, were taken charges some for localizations anoperinéales of  Crohn’s disease  . Results: Ano-perinéale was noted has 38 years an average age, dominated especially by the dents in 83% of the cases. The diagnosis was evoked in front of the presence of the épithélio-giganto-cellular granulome among all patients, and retained on the whole of the arguments clinical, endoscopic, histological and evolutionary. The surgical treatment was a fistulectomy or a fistulotomy associated with drainage in 10 cases and a double fissurectomy with anoplastie at two others. The average retreat was of 19.42mois. The cicatrization was considered to be good in 3 cases, slow in 3cas, an anal stenos moderate in a case and a relapse of fistula in a case. On the functional level, one noted a hypotonic in 5cas and an anal incontinence at a case. Discussion: The anoperinéal lesions of Crohn’s disease are frequent, often awkward, chronic, repeating, extensive, complex and of difficult treatment. The treatment of these lesions remains still discussed, partly because of the difficulties of evaluation related to their diversity and their complexity. Currently the contribution of the modern medical treatment made it possible to avoid any surgical aggression which is likely to involve or to worsen disorders of the continence except required. Conclusion: The medical treatment must be always prescribed in first intention. As for the surgical treatment, it should be considered only in the event of no active Crohn’s disease.Introduction : L’atteinte ano-perinéale au cours de la maladie de Crohn est relativement fréquente et de traitement difficile. Nous rapportons une étude rétrospective dont le but est de discuter la prise en charge thérapeutique medico-chirurgicale de ces lésions. Matériels et méthodes : Une étude rétrospective, entre le premier Janvier 2000 et le 31 Décembre 2005 avec un recul de 19 mois, faite d’une série de12 patients opérés pour maladie de Crohn ano-perinéale au sein de service de chirurgie viscérale et proctologique II de l’hôpital militaire d’instruction Mohamed V, Résultats : La maladie de Crohn ano-perinéale a été notée à un âge moyen de 38 ans avec une prédominance masculine, dominé surtout par les fistules dans 83% des cas. Le diagnostic a été évoqué en postopératoire, devant la présence du granulome épithélio-giganto-cellulaire chez tous les malades, et retenu, après un bilan complémentaire réalisé à distance, sur l’ensemble des arguments cliniques, endoscopiques, histologiques et évolutifs. Un bilan de la maladie crohnienne a été réalisés, les LAP, en rapport avec la maladie de Crohn, étaient isolées chez  8 patients et associée à des lésions intestinales méconnues chez 4 patients. Le traitement chirurgical a été une fistulectomie ou une fistulotomie associée à un drainage en séton(10cas) et une double fissurectomie avec anoplastie (2cas). Le recul moyen était de 19 mois. La cicatrisation a été jugée bonne dans 3 cas, lente dans 3cas, une sténose anale modérée a été notée dans un cas et une récidive de fistule dans un cas. Sur le plan fonctionnel, on a noté une hypotonie sphinctérienne dans 5cas et une incontinence anale chez un cas. Discussion : Les lésions anoperinéales de la maladie de Crohn sont fréquentes, souvent gênantes, chroniques, récidivantes, extensives, complexes et de traitement difficile. Le traitement de ces lésions reste encore controversé, en partie du fait des difficultés d’évaluation liées à leur diversité et à leur complexité. Actuellement l’apport du traitement médical moderne permet d’éviter toute agression chirurgicale qui risque d’entraîner ou d’aggraver des troubles de la continence sphinctérienne sauf nécessité. Conclusion : Le traitement médical doit être toujours prescrit en première intention. Quant au traitement chirurgical, il ne doit être envisagé qu’en cas l’absence de maladie de Crohn active

L’évolution fatale d’une thrombose de la veine porte

La thrombose du système portal est rare et ses étiologies sont multiples. Nous rapportons le cas d’un jeune patient de 26 ans, sans antécédents pathologiques particuliers admis pour douleurs abdominales diffuses d’installation brutale. Le diagnostic de la thrombose porte a été établi par le scanner abdominal sans mise en évidence d’un foyer infectieux intra-abdominal. Le bilan biologique a mis en évidence une hyperleucocytose mais la procalcitonine était négative. Le traitement anticoagulant a été démarré le jour de l’admission et le patient est décédé le jour même.  

Treatment adherence and BMI reduction are key predictors of HbA1c one year after diagnosis of childhood Type 2 Diabetes in UK

Background/Objective: Type 2 Diabetes (T2DM) is increasing in childhood especially among females and South-Asians. Our objective was to report outcomes from a national cohort of children and adolescents with T2DM 1 year following diagnosis. Methods: Clinician reported, 1-year follow-up of a cohort of children (<17 years) diagnosed with T2DM reported through the British Paediatric Surveillance Unit (BPSU) (April 2015-April 2016). Results: One hundred (94%) of 106 baseline cases were available for review. Of these, five were lost to follow up and one had a revised diagnosis. Mean age at follow up was 15.3 years. Median BMI standard deviation scores (SDS) was 2.81 with a decrease of 0.13 SDS over a year. HbA1c <48 mmol/mol (UK target) was achieved in 38.8%. logHbA1c was predicted by clinician reported compliance and attendance concerns (β = 0.12, P = <0.0001) and change in body mass index (BMI) SDS at 1-year (β = 0.13, P=0.007). In over 50%, clinicians reported issues with compliance and attendance. Mean clinic attendance was 75%. Metformin was the most frequently used treatment at baseline (77%) and follow-up (87%). Microalbuminuria prevalence at 1-year was 16.4% compared to 4.2% at baseline and was associated with a higher HbA1c compared to those without microalbuminuria (60 vs 49 mmol/mol, P = 0.03). Conclusions: Adherence to treatment and a reduction in BMI appear key to better outcomes a year after T2DM diagnosis. Retention and clinic attendance are concerning. The prevalence of microalbuminuria has increased 4-fold in the year following diagnosis and was associated with higher HbA1c

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Global economic burden of unmet surgical need for appendicitis

Background: There is a substantial gap in provision of adequate surgical care in many low-and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods: Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results: Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US $92 492 million using approach 1 and$73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was $95 004 million using approach 1 and$75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion: For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p&lt;0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p&lt;0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised
