Poultry Preslaughter Operations in Hot Environments: The Present Knowledge and the Next Steps Forward.

Poultry production faces significant challenges, including high feed prices, diseases, and thermal stress, which impact broiler welfare and productivity. Despite advances in cooling technologies and ventilation, preslaughter operations still lead to considerable losses. This review highlights the need for the improved management of thermal environments and animal logistics. Preslaughter operations typically involve fasting broilers for 8-12 h to reduce gastrointestinal contents and contamination. Following fasting, broilers are caught, crated, and transported. Stress levels vary based on distance and conditions, with manual catching often causing stress and injuries. Catching should occur during cooler periods to minimise these issues, and transport conditions must be carefully managed. Lairage, the waiting period after transport, should be kept short (1-2 h) in climate-controlled environments to avoid stress and deterioration. Proper handling and efficient unloading are essential to prevent injuries and reduce economic losses. Stunning methods, such as electronarcosis and a controlled atmosphere, aim to minimise suffering before slaughter, though practices vary culturally and religiously. Logistics and real-time monitoring technology are crucial for enhancing animal welfare during transportation. Effective planning and the optimisation of transport processes is vital for reducing stress and losses, especially with regard to rising global temperatures and production demands.

Assessment of severity and avoidability of adverse drug reactions in neonates: a reproducibility study of the Hartwig tool and LAAT.

OBJECTIVE: Tools for classifying adverse drug reactions (ADRs) have not yet been validated in the context of the neonatal intensive care unit (NICU). The study aims to investigate the inter-rater reliability of the Hartwig tool and the Liverpool avoidability assessment tool (LAAT) in assessing the severity and avoidability of ADR cases in hospitalized neonates. METHODS: An observational and prospective study was conducted in the NICU of a maternity hospital in Natal, Brazil. The Hartwig tool and LAAT were employed to assess the severity and avoidability of ADRs, respectively. Three experienced clinical pharmacists independently assessed all ADR cases. Inter-rater reliability was measured using Cohen's kappa coefficient (k) with corresponding 95% confidence intervals (CI). RESULTS: Among 79 ADR cases, the mean gestational age was 29.7 ± 4.4 weeks, and the birth weight averaged 1446.0 ± 1179.3 g. The assessment of ADR severity using the Hartwig tool revealed a significant overall correlation (overall k = 0.573; 95% CI 0.395 to 0.753) with exact agreement (EA) and extreme disagreement (ED) rates between evaluators of 86.5% and 2.5%, respectively. However, no statistically significant correlation was observed for determining avoidability using the LAAT (overall k = 0.017; 95% CI - 0.048 to 0.082), with an EA rate of 83.6% and ED rate of 10.1%. CONCLUSION: The Hartwig tool demonstrates good reproducibility among different evaluators in determining the severity of ADRs, unlike the LAAT for assessing avoidability.

[Argentinean registry on the management of Helicobacter pylori infection: effectiveness and safety of first line treatment]. / Registro argentino para el manejo de la infección por Helicobacter pylori: efectividad y seguridad de los esquemas de primera línea de tratamiento.

INTRODUCTION: The optimal management of Helicobacter pylori (H pylori) infection remains unclear. Updated information concerning local data is needed to design the best strategy to treat H. pylori infection to reach high eradication rates. The Argentinean Registry (Hp-ArgReg) on H. pylori management was launched to monitor the eradication practices of gastroenterologists. The objective was to assess the effectiveness and safety of firstline H. pylori treatment in Argentina. MATERIALS AND METHODS: A multicenter prospective registry of the clinical practice of the Argentinean gastroenterologists concerning H. pylori infection (Hp-ArgReg) was developed. Variables included: patient demographic information, previous eradication attempts, prescribed treatment, adverse events, compliance and outcome. RESULTS: Overall, 800 patients were included and 727 patients received first-line empirical treatment. The most frequent treatment indications were dyspepsia (78%) and gastroduodenal ulcer (12%). Among first-line treatments, quadruple therapies (with or without bismuth) achieved eradication rates of 94.9%, while triple therapies achieved eradication rates of 78.9%. Quadruple therapies were significantly more effective than triple therapies (P < 0.01, OR 5, CI 2.95-8.6). Sequential therapy with zinc showed an effectiveness of 95.6%. Adverse events were reported in 29% of the cases (mainly mild) and tolerance was quite similar among therapies. CONCLUSION: in Argentina, Quadruple therapies with or without bismuth and sequential therapy with zinc showed an H. pylori eradication effectiveness of over 90% in real clinical practice. Local Registries for H pylori management could help to control the spread of antibiotic resistance.

Introducción: El óptimo manejo de la infección por Helicobacter pylori (H. pylori) es objeto de debate. Contar con datos locales ayudaría a lograr altas tasas de erradicación. El Registro Argentino H. pylori (RegArg-Hp) se estableció con el objetivo de monitorear el manejo local de la infección. El objetivo fue describir la efectividad y seguridad de las terapias empíricas de primera línea para la erradicación del H. pylori utilizadas en Argentina. Materiales y métodos: Registro prospectivo, multicéntrico, de la práctica clínica de los gastroenterólogos argentinos. Se incluyeron datos demográficos de pacientes con infección por H. pylori, intentos previos de erradicación, tratamiento indicado, eventos adversos, cumplimiento y erradicación. Resultados: De 800 pacientes incluidos, 727 recibieron un tratamiento empírico de primera línea. Las indicaciones de tratamiento más frecuentes fueron dispepsia (78%) y úlcera gastroduodenal (12%). Entre los tratamientos de primera línea, las terapias cuádruples (con o sin bismuto) lograron tasas de erradicación del 94.9% mientras las terapias triples tasas de erradicación del 78.9%. Las terapias cuádruples fueron significativamente más efectivas que las triples (P < 0.01, OR 5, IC 2.95-8.6). La terapia secuencial con zinc mostró una efectividad del 95.6%. Se reportaron eventos adversos en el 29% de los pacientes, generalmente leves y con una tolerancia similar entre las diferentes terapias. Conclusiones: En Argentina, las terapias cuádruples con o sin bismuto y la secuencial con zinc presentaron una efectividad de erradicación de H. pylori superior al 90%. La implementación de registros locales podría contribuir al control de la resistencia a los antibióticos.

Occupational accidents in mining workers: scoping review of studies published in the last 13 years.

OBJECTIVE: Mining activity represents one of the most hazardous occupations related to health, with 8% of fatal injuries concentrated in this sector worldwide. Thus, it is crucial to timely identify the factors involved in such injuries. We aimed to explore the sociodemographic and occupational/organisational factors associated with injuries, causative agents and subsequent disabilities and fatality of workers exposed to occupational injuries in the mining sector. DESIGN: A secondary scoping review was conducted following the Joanna Briggs Institute guidelines. DATA SOURCES: Scopus, Embase, Virtual Health Library, SciELO and PubMed databases were searched in February 2022 and updated in October 2023. The protocol was developed in April 2022. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included observational studies published within the last 13 years (2010-2022) which provided information on injuries of the mining workers and reported associated factors as well as health consequences. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers examined the eligibility criteria, screened and coded the extracted information using prevalidated data extraction tools, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Extension for Scoping Reviews reporting guidelines. RESULTS: A total of 123 studies were found, of which nine were selected for inclusion in this review. Participants were between 15 and 80 years old, and the rate of injuries ranged from 4.4% to 10.6% of reported cases. Among the total selected studies, mechanical agents were identified as the leading cause of injuries in six studies. The factors associated with injuries included age, gender (female) and biochemical characteristics. On the other hand, occupational and organisational factors encompassed work shift, outsourcing (contractors) and less than 2 years of experience in the sector. CONCLUSION: This review emphasises that both work-related and individual characteristics are significantly related factors of injuries. Moreover, commonly reported health consequences of injuries encompass mortality, average days lost and permanent, partial or total disability.

SalmoFree® Phage Additive Proves Its Safety for Laying Hens.

Background: The avian pathogen Salmonella Gallinarum causes avian typhosis in laying hens, leading to high mortality rates among adult birds, which poses a significant problem in the poultry industry. Various products, such as vaccines, antibiotics, probiotics, and disinfectants, are commonly used to prevent and control the disease on farms. An alternative to these products is the use of bacteriophages, which may effectively prevent the colonization of S. Gallinarum. Materials and Methods: This study evaluated the safety of SalmoFree®, a bacteriophage cocktail, administered to 276 laying hens from the first week of age until the 28th week. The hens were divided into two groups: a control group (138 birds) and a treatment group (138 birds). Over the 28-week period, eight doses of SalmoFree® (∼1010 UFP per bird) were administered via drinking water in a controlled environment. Results: The results indicate that the consumption of SalmoFree® has no adverse effects on bird health or zootechnical parameters. Additionally, there is a trend toward improving weight homogeneity (up to 19%), feed conversion (up to 68%), and egg weight (up to 2.7%). The detection of phages by PCR in cloacal swabs suggests that they persist in birds for 2 to 8 weeks post-ingestion. Furthermore, phages were detected in organs and eggshells, indicating that they provide protection beyond the gut. Conclusion: The study demonstrates that SalmoFree® is safe for use in laying hens and may offer additional benefits, such as improved zootechnical parameters and extended protection against S. Gallinarum through the persistence of bacteriophages in the birds.

Cross-cultural adaptation and validation of the Hospital Survey on Patient Safety questionnaire for a Chilean hospital.

BACKGROUND: Hospital Survey on Patient Safety version 2.0 (HSOSPS 2.0) from the Agency for Healthcare Research and Quality enables hospitals to gather the information needed to evaluate the patient safety culture within their institution. However, version 2.0 has not been widely implemented in Chile. This study aims to customize and validate the original HSOSPS 2.0 for a Chilean hospital. METHODS: Translation and cross-cultural adaptation, content validity through a group of experts, and a pilot test with cognitive pretest were applied to 259 participants from the nursing team in 11 hospital services to study construct validity and reliability. RESULTS: In the current study, a version of the questionnaire adapted to the Chilean cultural context showed excellent content validity with an index of 0.982 (S-CVI). After conducting exploratory factor analysis, a new model with 7 dimensions and 23 questions was proposed, down from the original 10 dimensions and 32 questions. This new model explains 71% of the variability. The model's goodness of fit indicators were CFI=0.995, TLI=0.994, and RMSEA=0.048. The results of McDonald's Omega showed high overall reliability with 0.9325. CONCLUSIONS: This study provides a validated measurement instrument that contributes to improving patient safety conditions at the level of the hospital nursing team in highly complex establishments in Chile. However, the dimensions, such as the number of items, were reduced This questionnaire can be used in future nursing research by expanding the sample among health professionals in Chile. RELEVANCE TO CLINICAL PRACTICE: Applying this version of the questionnaire will be highly beneficial for clinical administrators and nursing staff. It will improve their care practices and promote patient safety in public hospitals in Chile, as well as assist in enhancing nursing policies.

Do Temperature Abuses Along the Frozen Açaí Pulp Value Chain Increase Microbial Hazards?

Does temperature abuse during storage, distribution, marketing, and consumption of unpasteurized frozen açaí pulp increase microbial hazards? This study investigated the behavior of potentially pathogenic (Escherichia coli, Listeria monocytogenes and Salmonella spp.) and spoilage (mesophilic bacteria, yeasts and molds) microorganisms in two simulated thawing conditions: under refrigeration and at room temperature. The effect of repeated cold chain abuse was observed by thawing and refreezing (-20°C) açaí pulp four times over a period of 90 days. Freezing resulted in inhibition of all microorganisms except for mesophilic aerobic bacteria in one single sample. After thawing at 5°C, the kinetic parameters obtained by the Weibull model indicated that mesophilic aerobic bacteria, yeasts and molds and L. monocytogenes showed a longer inactivation time with δ values reaching 35, 126, and 46 days, respectively. The shortest inactivation time for a reduction of 4 log CFU.g-1 was for E. coli. The concentration of Salmonella spp. and L. monocytogenes in control samples was higher (p < 0.01) than in samples exposed to abusive conditions after 90 days of storage. The results indicate that the abusive thawing conditions studied do not increase the potential hazards of pathogens.

Reduction of catheter-associated bloodstream infections: Effectiveness of the continuous quality improvement method at a university hospital in Colombia / Reducción de las infecciones del torrente sanguíneo asociadas a catéter: efectividad del método de mejora continua de la calidad en un hospital universitario en Colombia

Abstract Introduction: Central Line-Associated Bloodstream Infections (CLABSI) are preventable and potential fatal events, frequent in critical patient care. By mid-2018 an increase was noted in the incidence rate of CLABSI at a high complexity institution in Colombia, demanding immediate interventions to lower those numbers. Objective: To assess the effectiveness of the continuous quality improvement methodology (CQI) to lower the incidence rate of CLABSI at a university hospital in Bogotá, Colombia. Methods: Longitudinal, prospective study implementing a multifaceted intervention in accordance with the CQI methodology. The project was developed at a high complexity university hospital in Bogotá, Colombia, between July 2018 and December 2019. A root cause analysis was consecutively conducted prioritizing contributing factors, gathering ideas for improvement, building a strategy and prioritizing the implementation plan. Results: The CQI methodology enabled the identification of areas susceptible of catheter insertion and management errors at the institution; additionally, it allowed for the prioritization of the areas requiring intervention through consecutive test cycles for improvement ideas. The reduction and sustainability of insertion-related CLABSI was accomplished three months after the start of the interventions, achieving a zero value. The implementation of improvement ideas aimed at reducing the events associated with catheter maintenance was also able to reduce the incidence to zero, until the end of the period of observation of the study. Conclusions: It is feasible to implement CQI in settings similar to the one herein described, in order to efficiently reduce CLABSIs.

Resumen Introducción: Las infecciones del torrente sanguíneo asociadas a catéter (ITS/AC) son eventos prevenibles y potencialmente fatales, comunes en el contexto del cuidado de pacientes críticos. A mediados de 2018 se presentó un incremento en la tasa de incidencia de ITS/AC en una institución colombiana de alta complejidad, obligando a realizar intervenciones inmediatas para lograr una reducción de estas cifras. Objetivo: Evaluar la efectividad del método de mejoramiento continuo de la calidad (MCC) para la reducción de la tasa de incidencia de ITS/AC en un hospital universitario en Bogotá, Colombia. Métodos: Estudio longitudinal, prospectivo, en el que se implementa una intervención multifacética siguiendo la metodología de MCC. El proyecto se desarrolló en un hospital universitario de alta de complejidad de Bogotá, Colombia, entre julio de 2018 y diciembre de 2019. Se realizaron consecutivamente un análisis de causa raíz, priorización de factores contribuyentes, recuperación de ideas de mejora, construcción de la estrategia y priorización del plan de implementación. Resultados: El método de MCC permitió la detección de zonas susceptibles de presentación de errores en la inserción de catéteres y su mantenimiento en la Institución, además permitió priorizar las áreas por intervenir mediante ciclos consecutivos de prueba para las ideas de mejora. Se logró la reducción y sostenibilidad de la ITS/AC asociada a inserción luego de tres meses de iniciar las intervenciones, logrando valores de cero. La implementación de ideas de mejora dirigidas a reducir los eventos relacionados con el mantenimiento de catéteres también logró reducirlos a cero hasta la terminación del periodo de observación de este estudio. Conclusiones: Es factible implementar MCC en contextos como el aquí presentado para reducir de manera eficiente las ITS/AC.

Incidencia de las enfermedades transmitidas por alimentos en Ecuador / Incidence of foodborne diseases in Ecuador

RESUMEN Con el objetivo de describir las tasas de incidencia por cada 100 000 habitantes de los casos de enfermedades transmitidas por alimentos (ETA) durante el periodo 2015-2020 en Ecuador se realizó un análisis secundario de los registros de vigilancia epidemiológica y de las proyecciones poblacionales del Instituto Nacional de Estadística y Censos. Se reportaron 113 695 casos con una incidencia superior a los 100 casos por cada 100 000 habitantes (2015-2019). En el 2020 los registros son considerablemente inferiores a los reportes de años anteriores. La mayoría de los casos se reportaron como «otras intoxicaciones alimentarias¼. Las tasas de incidencia de ETA más altas se observaron en la región amazónica. En general existe una marcada variabilidad anual en la incidencia de las ETA según las regiones geográficas del Ecuador. En conclusión, las ETA representan un problema de salud pública en el Ecuador. Se deben diseñar estrategias preventivas integrales con especial énfasis en la región amazónica.

ABSTRACT In order to describe the incidence rates per 100 000 population of foodborne disease (FBD) cases during the period 2015-2020 in Ecuador, we carried out a secondary analysis of epidemiological surveillance records and population projections from the National Institute of Statistics and Census. A total of 113,695 cases were reported with an incidence of more than 100 cases per 100 000 population (2015-2019). In 2020, the records are considerably lower than those reported in previous years. Most cases were reported as "other food poisoning". The highest incidence rates of FBD were found in the Amazon region. In general, there is a marked annual variability in the incidence of FBD according to the geographic regions of Ecuador. In conclusion, FBD represent a public health problem in Ecuador. Comprehensive preventive strategies should be designed with special emphasis on the Amazon region.

First-trimester medication abortion via telemedicine: A retrospective cohort study.

Background: Following the decriminalization of abortion in Colombia and amidst a global health crisis due to COVID-19, Profamilia implemented a telemedicine-assisted first-trimester Medication Abortion (MAB) program. This is an opportunity to reduce inequalities in access and to promote empowerment and sexual and reproductive rights. This study aims to describe socio-demographic and clinical characteristics of users and to assess its effectiveness and safety. Study design: A retrospective cohort study. Methods: The study analyzed data from users who received Profamilia's telemedicine abortion services between August 2021 and August 2022 (n = 3073). A descriptive analysis of their sociodemographic and clinical characteristics was performed, grouping, and comparing them according to follow-up status and abortion outcome. Effectiveness was assessed by the percentage of complete abortions without surgical intervention, and safety by the incidence of complications, potential adverse events, and potentially dangerous signs. Results: Most of the users were less than 8 weeks gestation at the start of treatment (88.3 %), from low socioeconomic strata (84.8 %), affiliated to the subsidized healthcare system (87.6 %), with educational levels up to secondary school (81.6 %), between 18 and 35 years (87.4 %), from urban areas (97.8 %) and singles (90,8 %). 94.9 % of users had a complete abortion using medication, and 0.3 % of cases reported complications. Conclusions: First-trimester MAB through telemedicine in the Latin American context is an effective and safe choice. Telehealth is an important strategy to expand access to safe abortion care, especially for those with limited financial means or educational backgrounds. Rural and marginalized populations need more attention to improve access.

Anise essential oil immobilized in chitosan microparticles: a novel bactericidal material for food protection.

Foodborne infections in humans are one of the major concerns of the food industries, especially for minimally processed foods (MPF). Thereby, the packaging industry applies free chlorine in the sanitization process, ensuring the elimination of any fecal coliforms or pathogenic microorganisms. However, free chlorine's propensity to react with organic matter, forming toxic compounds such as trihalomethanes and haloacetic acid. Therefore, the present work aimed to synthesize a novel organic biomaterial as an alternative to free chlorine. Chitosan microparticles were produced, with Pimpinella anisum (anise) essential oil immobilized in the biopolymer matrix (MPsQTO). The characterization of this biomaterial was done through GC-MS/MS, FT-IR, and SEM. Antimicrobial assays proved that the MPsQTO presented antibacterial activity for Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa, and Bacillus subtilis at 300 µL mL-1 of concentration. The fluorescence microscope also showed the MPsQTO targets the cytoplasmatic membrane, which is responsible for cell death in the first minutes of contact. Studies with the mutant B. subtilis (amy::pspac-ftsZ-gfpmut1) and the Saccharomyces cerevisiae D7 also proved that the biomaterial did not affect the genetic material and did not have any mutagenic/carcinogenic effect on the cells. The sanitization assays with pumpkin MPF proved that the MPsQTO is more effective than free chlorine, increasing the shelf-life of the MPF. Consequently, the novel biomaterial proposed in this work is a promising alternative to traditional chemical sanitizers.

Improvement of blood transfusion safety using the chemiluminescence technique for viral marker screening of blood donors in sub Saharan Africa.

INTRODUCTION: Sub-Saharan Africa struggles continuously with insufficient resources and inadequate infrastructure that hinder the establishment of a safer blood supply despite improvements in transfusion safety over recent decades. This study aimed to evaluate the impact of the chemiluminescence technique in combination with immunoenzymatic and immunochromatographic tests for viral marker screening of hepatitis B (HBV), hepatitis C (HCV) and human immunodeficiency virus (HIV) in donated blood in a country of sub-Saharan Africa. METHOD: This study was conducted in a population of 113,406 blood donors at the National Centre of Blood Transfusion in Senegal. The data were obtained from the 'INLOG' software and donor registers. Statistical analyses used Excel 2010 and Epi Info v6. Screening for HBsAg viral markers, anti-HCV Ab, HIV p24 Ag, anti-HIV1 and anti-HIV2 antibodies were first carried out using the chemiluminescence technique. Blood donations screened positive for HBV or HCV were retested in a second chemiluminescence equipment. HIV-positive donations and their controls were subjected to solid phase immunochromatographic and indirect enzyme immunoassay techniques. RESULTS: The prevalence among donors of HBV was 8.39 %, 0.56 % for HCV and 0.18 % for HIV. Of the donors tested positive for HIV in screenings and in doubled-controls, only 61.54 % were confirmed by the alternative tests; 34.02 % were negative and 4.44 % discordant between the three techniques. CONCLUSION: This study shows the importance of introducing the chemiluminescence technique in association with serological screening of transfusion-transmitted viruses to improve blood supply safety in low-income countries.

Thromboprophylaxis in lower limb amputation surgery.

Background: Lower limb amputation surgery is associated with a high risk of venous thromboembolism. There is evidence that pharmacological thromboprophylaxis is not widely prescribed to patients undergoing this type of procedure. Objectives: To investigate the profile of the thromboprophylaxis practices of angiologists and vascular surgeons in Brazil during the perioperative period of lower limb amputation surgery and conduct a descriptive analysis of the findings. Methods: This is a cross-sectional, descriptive study, with simple probabilistic sampling, carried out with angiologists and vascular surgeons working in Brazil. Data were collected through electronic questionnaires, from February to June 2023. Results: There were 237 respondents, 58.6% of whom conduct thrombotic risk stratification. Of these, 86.3% use the Caprini score. Only 27% of participants stratify patients' bleeding risk. Low molecular weight heparin is the medication of choice for 85.7% of study participants, 78.9% of whom use a dosage of 40 IU per day. Around 46.8% use direct oral anticoagulants in addition to low molecular weight heparin and rivaroxaban is the drug they most often prescribe (94.6%). A little more than half (51.15%) routinely recommend pharmacological thromboprophylaxis until hospital discharge. Conclusions: The study revealed the heterogeneous nature of conduct related to prescription of pharmacological thromboprophylaxis, highlighting the need for more studies to support prophylaxis decision-making in this patient population.

Analysis of the regulations concerning circular economy and its relationship to the reduction of food loss and waste on an international level: A review.

The term food loss and waste (FLW) refers to discarded food during the different stages of the food chain. Food loss occurs during the initial stages of the food chain, and food waste occurs during the final stages. The relation between FLW and circular economy (CE) is particularly important for countries which are beginning to implement actions or regulations on this topic. These proposals may have an impact in strategic sectors of their economy. The objective of this review document was to analyse the regulations of FLW and CE in some countries located throughout the European Union, Asia, Africa and Latin America. To fulfil this objective, FLW and CE regulations were identified and analysed in 12 countries located in the aforementioned regions. The analysis showed that France, Spain, Japan and Uruguay included objectives related to FLW in their CE legislations focusing on food waste reduction, whereas China, Chile, Argentina and Mexico did not include FLW in their CE legislations. African countries did not have CE legislations in place yet. France and Japan have had more success in the reduction of FLW. In conclusion, CE regulation should include FLW regulation to achieve more efficiency at reducing and reusing these residues.

Objective: The objective of this study was to assess the cleaning quality of aspirator instruments used in neurosurgical procedures. Methods: The experimental study was conducted at the materials and sterilization center, as well as the microbiology laboratory, of a philanthropic hospital in Brazil. A study protocol was implemented, which involved the analysis of 10 samples of Yasargil aspirators with varying dimensions. The samples were subjected to protein tests to detect the presence of organic matter and microbiological analysis. Descriptive statistics were used to analyze the data. Results: The results indicated that 40% of the instruments tested positive for protein after manual cleaning. Furthermore, after automated cleaning, samples showed an increased microbiological load, with Escherichia coli accounting for 20% and Klebsiella aerogenes for 10% of the identified microorganisms. Conclusion: This study provides evidence of failures in the cleaning process of healthcare products and highlights the presence of biofilm in the pipes, thereby compromising the drinking water quality standard.

Precise Needle and Cannula Placement in the Forehead During Aesthetic Procedures: Can Device and Angulation Influence Accuracy? A Fresh Frozen Specimen Study.

INTRODUCTION: Myomodulation is a technique aimed at enhancing the dynamics of muscle contraction and relaxation through methods like hyaluronic acid (HA) injection. Achieving optimal outcomes depends on the precise placement of the injected product within the targeted anatomical plane. This is particularly important in the forehead, an area with elevated vascular risk. The selected treatment techniques must ensure both efficacy and safety. This study aims to assess the anatomical precision of HA injections in the forehead using different techniques and devices. METHODS: Four fresh frozen specimens were injected with HA by five experienced board-certified plastic surgeons using three different techniques/devices: (1) a 50 mm, 22G microcannula; (2) a 13 mm, 27G needle with the bevel down at a 45-degree angle; and (3) the same needle positioned at a 90-degree angle. Ultrasound analysis was used to evaluate the precision of each approach. RESULTS: Both the cannula technique and the needle technique with the bevel down at a 45-degree angle consistently delivered the filler to the supraperiosteal layer in 100% of cases without spreading. However, the 90-degree needle technique, despite correct placement on the periosteum, resulted in filler dispersion across multiple layers. CONCLUSION: The accuracy of filler placement in the forehead is influenced by the choice of device and its angulation. It is recommended to use a cannula with the entry point at the frontalis crest or a needle angled at 45 degrees to the skin. The use of a needle at a 90-degree angle should be avoided to ensure precise placement and avoid filler migration.
