Fractura craneal deprimida congénita ("fractura ping-pong") en neonatos como diagnóstico diferencial de maltrato físico / Congenital depressed skull fracture ("ping-pong" fracture) in newborn infants as a differential diagnosis of physical abuse

Las fracturas con hundimiento de cráneo sin una explicación clara sobre su origen orientan al traumatismo con un objeto romo y a la sospecha de maltrato infantil. En el caso de los bebés recién nacidos, su corta edad es un factor de vulnerabilidad y obliga a una exhaustiva evaluación. Ante la sospecha de maltrato infantil, resulta importante evaluar los diagnósticos diferenciales para realizar la intervención más adecuada posible. Es necesario evitar tanto intervenciones excesivas como omitir la intervención que sea necesaria. Las fracturas craneales deprimidas congénitas, descritas como "fracturas pingpong", son raras (0,3 a 2/10 000 partos). Pueden aparecer sin antecedentes traumáticos o en partos instrumentalizados. Se describe en este artículo el caso de un recién nacido con una fractura ping-pong como ejemplo de una fractura no intencional.

Depressed skull fractures without a clear explanation as to their origin point to trauma with a blunt object and suspected child abuse. In the case of newborn infants, their young age is a vulnerability factor and requires an exhaustive assessment. When child abuse is suspected, an assessment of the differential diagnoses is required to make the most appropriate intervention possible. Both an excessive intervention and an omission of a necessary intervention should be avoided. Congenital depressed skull fractures, described as "ping-pong fractures", are rare (0.3 to 2/10 000 births). They may appear without any trauma history or in instrumentalized childbirth. Here we describe the case of a newborn infant with a ping-pong fracture as an example of an accidental fracture.

The scores of VAS and ODI after operation were lower than those before operation (P<0.05), but there was no significant difference between the two groups (P<0.05).@*CONCLUSION@#Modified suspension reduction method combined with PVP surgery for osteoporotic thoracolumbar compression fractures has achieved good clinical results, which can effectively relieve lumbar back pain, restore vertebral height, correct kyphosis, improve lumbar function and patients' quality of life.

Distal tibiofibular syndesmosis fibular notch typing and its clinical significance based on CT / 解剖学报

Objective To investigate the morphological typing and clinical significance of the distal tibiofibular syndesmosis fibular notch based on CT images. Methods According to the inclusion and exclusion ceiteria‚ the imaging data of patients undergoing ankle joint CT examination were analyzed‚ and the inferior tibiofibular joint fibula notch was classified according to the morphological characteristics. The measurements included 8 distances. There were 123 males and 102 females‚ all of whom were Han nationality‚ aged 18-60 years old. Results Retrospectively analyzed the result of 225 patients from December 2013 to December 2022. The distal tibiofibular syndesmosis fibular notch was divided into four types according to morphological characteristics‚ C-shaped (50. 67%)‚ V-shaped (26. 67%)‚ flat-shaped (15. 11%) and L-shaped (7. 56%). The angle between the anterior and posterior facets of the flat shape (145. 56 ± 9. 25)° was the largest and the angle between the anterior and posterior facets of the L shape (125. 07 ± 13. 54)° was the smallest(P< 0. 05); the depth of the notch in the flat shape (3. 11 ± 0. 83) mm was the smallest and in the L shape (4. 47±1. 11) mm was the largest(P<0. 05);The posterior facet length (13. 06 ± 3. 56) mm and anterior tibiofibular gap (3. 83±1. 49) mm on left were larger than on the right side (P<0. 05); The posterior facet length (13. 36 ± 3. 46) mm‚ fibular notch depth (3. 93 ± 1. 10) mm and vertical distance of tibiofibular overlap (9. 10 ± 2. 55) mm larger in men than in women (P<0. 05). Conclusion In this study‚ the data related to the inferior tibiofibular syndesmosis notch were measured and divided into four types according to the shape. The flat inferior tibiofibular syndesmosis notch is more likely to have chronic ankle instability‚ and the fibula is more likely to move forward during anatomical reduction. The inferior tibiofibular syndesmosis of L-shaped and C-shaped notches is more prone to posterior displacement of fibula or poor rotation reduction during anatomical reduction.

Discussion on common problems after introducing "reduction factor" into different working hour systems in occupational exposure assessment in GBZ 2.1—2019 / 环境与职业医学

Occupational exposure limits for hazardous agents in the workplace—Part 1: Chemical hazardous agents (GBZ 2.1—2019) has been implemented since April 1, 2020. The document redefines the evaluation of occupational exposure by introducing a "reduction factor" to adjust the occupational exposure limits of chemical hazardous agents for long working hour systems to ensure a protection level reasonable for the workers and equivalent to conventional occupational exposure limits. This paper discussed common problems encountered in the context of using this adjustment strategy, such as the adjustment being unable to cover all working hours, and the adjustment of values of terms associated with occupational exposure limits. Corresponding solutions were proposed. Working cycle and average exposure time of each working cycle were introduced to evaluate the actual working hours of workers. Regarding involved terms, adjustments of their corresponding values were clarified according to their definitions and application scenarios. Examples were provided for occupational health service providers so that their occupational health practices could be carried out in a more scientific and reasonable manner.

The Electroacoustic Performance of Digital Noise Reduction Systems in Commercial Hearing Aids with Malay Speech-Plus-Noise Test Signals (Prestasi Elektroakustik Sistem Pengurangan Hingar Digital dalam Alat Bantu Pendengaran Komersial dengan Isyarat Ujian Pertuturan-Dalam-Bising Bahasa Melayu) / Jurnal Sains Kesihatan Malaysia

@#One of the most frequent complaints of individuals with hearing impairment is listening comfort in noisy environments. In order to improve listening comforts in background noise, digital noise reduction (DNR) systems are incorporated into hearing aids (HAs). Each hearing aid manufacturer has its proprietary algorithm for the DNR system. The amount of attenuation (dB) provided by the DNR system can be quantified using the hearing aid analyser. However, the standard test signals in the hearing aid analyser could not quantify the attenuation of DNR for speech mixed with noise signals. Therefore, this study aimed to (i) develop speech-plus-noise test signals that incorporate Malay sentences and (ii) quantify the efficacy of DNR systems in commercial hearing aids using the newly developed test signals. Six different brands of hearing aids with identical technology but from different manufacturers were subjected to electroacoustic testing utilising newly created Malay speech-in-noise test signals with and without DNR enabled. The total root-meansquare (RMS) gain reduction for each HA was calculated. The results show that the types of noise, the signal-to-noise ratio and the gender of the speaker have a significant effect (p<0.05) on the amount of gain reduction in the HA output as a result of the DNR system in each HA . In conclusion, the newly developed Malay speech-in-noise test signals can be used to verify the efficacy of DNR system in commercial hearing aids.

Comprehensive analysis of insulin products complex disulfide bonds structure by high resolution mass spectrum / 药学学报

The correct pairing of disulfide bonds maintains the correct folding mode and high-level structure formation of peptides and protein drugs, which is crucial for the quality control of products. In order to ensure that the disulfide bonds are correctly paired, disulfide bond analysis is an essential part of peptides and protein drug characterization. Mass spectrometry can be used to analyze disulfide bonds. However, insulin and its analogues have two pairs of disulfide bonds without restriction enzyme cutting site. Conventional collision-induced dissociation (CID) and high-energy induced cleavage (HCD) cannot accurately locate the complex disulfide bond. In our study, three methods were used to localize the complex disulfide, including enzyme digestion combined with key peptide fragment in source decay (ISD) fragmentation method, enzyme digestion combined with partial reduction alkylation method, intact protein source ISD and electron transfer dissociation (ETD) cleavage method, The applicability of insulin aspart, insulin lispro and insulin glargine were also investigated. This study provides a new way for the quality control of disulfide bonding mode of insulin and its analogues, and also provides a reference for the disulfide bond localization of peptides or proteins containing this complex disulfide bond.

Comparison of Sociodemographic and Radiographic Features in Distal Radio Fracture Treatment: Hand Surgeons versus Non-specialists / Comparação de características sociodemográficas e radiográficas no tratamento de fratura de rádio distal: Cirurgiões de mão versus não especialistas

Abstract Objective: This study evaluated sociodemographic and radiographic features of patients with distal radial fractures treated at a trauma hospital in southern Brazil, comparing those treated by hand surgery specialists (group 1) and non-specialists (group 2). Methods: This study consists of a retrospective cohort of 200 patients treated in 2020. After reviewing medical records and radiographs, the following parameters were analyzed: age, gender, trauma mechanism, laterality, associated comorbidities and fractures, fracture classification (AO), radial height, radial inclination, and volar inclination. Comparison of the two groups used the Student t-test, chi-square test, or Fisher exact test. Results: Most subjects were women (54%), sustained low-energy traumas (58%), and were left-handed (53%). Group 1 had a lower mean age (50.2 years); most of their subjects sustained high-energy trauma (54%) and had type C fractures (73%); type A fractures prevailed in group 2 (72%). Radiographs showed a significant difference regarding the mean radial inclination (21.5° in group 1 and 16.5° in group 2 [p < 0.001] in women, and 21.3° in group 1 and 17° in group 2 [p < 0.001] in men) and volar inclination (10.1° and 12.8° in groups 1 and 2, respectively [p < 0.001]). In addition, the absolute number of cases with reestablished anatomical parameters per the three evaluated variables was also significantly different; all parameters were better in group 1. Conclusion: Hand surgeons treated the most severe fractures and had the best radiographic outcomes.

O grupo 1 apresentou média de idade menor (50,2 anos), traumas de alta energia (54%), e fraturas tipo C (73%), enquanto no grupo 2 fraturas tipo A prevaleceram (72%). As radiografias apresentaram diferença significativa quanto à média de valores de inclinação radial (21,5° no grupo 1 e 16,5° no grupo 2 [p < 0,001] nas mulheres e, 21,3° no grupo 1 e 17° no grupo 2 [p < 0,001] nos homens) e inclinação volar (10,1° e 12,8° no grupo 1 e 2, respectivamente [p < 0,001]), bem como no número absoluto de casos que reestabeleceram os parâmetros anatômicos nas três variáveis avaliadas, sendo todos melhores no grupo 1. Conclusão: Os cirurgiões de mão trataram as fraturas mais graves e apresentaram os melhores resultados radiográficos.

Sofrimento psíquico, uso de drogas e trabalho / Psychic distress, drug use and work

Resumo Introdução: a política de atenção ao uso e abuso de álcool e outras drogas dos últimos anos demonstra suas limitações para responder às necessidades de atenção à saúde do(a) trabalhador(a) que usa essas substâncias para aliviar os efeitos adversos dos mecanismos hostis no contexto do trabalho. Objetivo: articular abordagens que reúnem um conjunto teórico-conceitual suficiente para abordar temas complexos e multicausais, como a relação entre o sofrimento psíquico e o trabalho, tendo como elemento principal o uso e abuso de álcool e outras drogas. Resultados: há evidências que apontam a relação entre mudanças no mercado de trabalho no contexto neoliberal, violência moral e ética no ambiente profissional e efeitos negativos sobre a saúde física-psíquica de trabalhadores. Evidenciou-se a necessidade de se romper com a lógica do funcionalismo subjetivista sobre o tema do uso e abuso de álcool e outras drogas relacionados ao trabalho. Conclusão: as estratégias políticas de atenção ao sofrimento psíquico decorrente do uso de álcool e outras drogas devem ir além das práticas focadas somente na abstinência e se basear na interface entre aportes teóricos integrativos, redução de danos e que considere a relação entre sofrimento e defesas dos sujeitos, o trabalho e o meio.

Abstract Introduction: policies aimed at use and abuse of alcohol and other drugs in recent years have shown their limitations in responding to the healthcare needs of workers who use and/or abuse alcohol and other drugs to alleviate the adverse effects from hostile work-related mechanisms. Objective: to articulate approaches that gather a theoretical-conceptual set that adequately addresses complex and multi-causal topics, such as the relation between psychological distress and work, with the use and abuse of alcohol and other drugs as their main element. Results: scientific evidence points out to the relation between neoliberal labor market changes, moral and ethical violence in the professional environment and negative effects on workers' physical and mental health. Studies argue about the need to break with the logic of subjectivist functionalism on the topic of work-related use and abuse of alcohol and other drugs. Conclusion: political strategies aimed at psychological suffering resulting from the use/abuse of alcohol and other drugs must go beyond practices solely focused on abstinence and include the interface between integrative theoretical contributions and harm reduction while considering the interaction between suffering and subjects' defenses, work and environment.

Effect of dental distance from implant and MAR algorithm on the detection of vertical root fracture in CBCT images

Three-dimensional cone-beam computed tomography (CBCT) has an important role in the detection of vertical root fractures (VRFs). The effect of artifact generation by high-density objects like dental implants on image quality was well documented. This study aimed to assess the effect of tooth-implant distance and the application of metal artifact reduction (MAR) algorithm on the detection of VRFs on CBCT scans. This study was conducted on 20 endodontically treated single-rooted teeth. VRFs were induced in 10 teeth, while the other 10 remained intact. The implant was inserted in the right second premolar socket area, and two teeth were inserted in right canine and right first premolar sockets area randomly and underwent CBCT with and without the application of MAR algorithm. SPSS 21 was used to analyze the results (alpha=0.05). According to the findings of this study, all four variables of sensitivity, specificity, accuracy, and positive predictive values in diagnosis were higher in cases without MAR software at both close(roots in first premolar sockets) and far distances (roots in canine sockets) from the implant. However, the highest rate of diagnosis accuracy of the first and second radiologists was in the far distance group from the implant without MAR, and the lowest rate of diagnosis accuracy in the first and second radiologists was in the close distance to the implant. Applying MAR algorithm had no positive effect on detection of VRFs on CBCT scans in both close and distant scenarios.

La tomografía computarizada de haz cónico tridimensional (CBCT) tiene un papel importante en la detección de fracturas radiculares verticales (VRF). El efecto de la generación de artefactos por objetos de alta densidad como los implantes dentales en la calidad de la imagen está bien documentado. Este estudio tuvo como objetivo evaluar el efecto de la distancia entre el diente y el implante y la aplicación del algoritmo de reducción de artefactos metálicos (MAR) en la detección de VRF en escaneos CBCT. Este estudio se realizó en 20 dientes uniradiculares tratados endodónticamente. Se indujeron VRF en 10 dientes, mientras que los otros 10 permanecieron intactos. El implante se insertó en el área del alveolo del segundo premolar derecho, y dos dientes se insertaron en el canino derecho y en el área del alvéolo del primer premolar derecho al azar y se sometieron a CBCT con y sin la aplicación del algoritmo MAR. Se utilizó SPSS 21 para analizar los resultados (alfa=0,05). De acuerdo con los hallazgos de este estudio, las cuatro variables de sensibilidad, especificidad, precisión y valores predictivos positivos en el diagnóstico fueron más altas en los casos sin el software MAR tanto en distancias cercanas (raíces en las cavidades de los primeros premolares) como lejanas (raíces en las cavidades de los caninos) del implante. Sin embargo, la tasa más alta de precisión diagnóstica del primer y segundo radiólogo fue en el grupo de mayor distancia al implante sin MAR, y la tasa más baja de precisión diagnóstica en el primer y segundo radiólogo fue en la distancia cercana al implante. La aplicación del algoritmo MAR no tuvo un efecto positivo en la detección de VRF en escaneos CBCT en escenarios cercanos y distantes.

Radial Nerve Supracondylar Block Versus Fracture Hematoma Block. Comparison of Their Efficacy in Cases of Fractures of the Distal Third of the Radius / Bloqueio supracondilar de nervo radial versus bloqueio de hematoma de fratura. Comparativo de sua eficácia em casos de fraturas do terço distal do rádio

Abstract Objective The present study compares the analgesic efficacy of two techniques to perform non-surgical reduction: fracture hematoma block and radial nerve supracondylar block. Methods Forty patients with fractures of the distal third of the radius, who required reduction, were selected in a quasi-randomized clinical trial to receive one of the anesthetic techniques. All patients signed the informed consent form, except for those who did not wish to participate in the study, had neurological injury, had contraindication to the procedure in the emergency room, or with contraindication to the use of lidocaine. To measure analgesia, the numerical pain rate scale was used at four different moments: preblock, postblock, during reduction, and after reduction; then three differences were calculated: the first between before and after blocking; the second between during reduction and after blockade; and the third between before blocking and after reduction. Results The fracture hematoma and supracondylar block groups showed the following mean values, respectively: 3.90 (1-10) and 3.50 (-6-10) in difference 1; 4.35 (-5-10) and 5.00 (-3-10) in difference 2; and 4.65 (1-10) and 3.80 (-3-10) in difference 3. Conclusion Both techniques proved to be efficient for analgesia, with mild superiority of hematoma block, but without statistical significance.

Resumo Objetivo O estudo compara a eficácia analgésica de duas técnicas para realizar redução incruenta: o bloqueio de hematoma da fratura e o bloqueio supracondilar de nervo radial. Métodos Quarenta pacientes com fraturas do terço distal do rádio, que necessitassem redução, foram selecionados em um ensaio clínico quasi-randomizado, para receber uma das técnicas anestésicas. Todos os pacientes assinaram o termo de consentimento ou assentimento, com exceção daqueles que não desejassem participar do estudo, tivessem lesão neurológica, com contraindicação ao procedimento na sala de emergências, ou com contraindicação ao uso da lidocaína. Para aferir a analgesia foi utilizada a escala numérica da dor em quatro momentos distintos: pré-bloqueio, pós-bloqueio, durante a redução e após a redução; em seguida, foram calculadas três diferenças: a primeira entre antes e após o bloqueio; a segunda entre durante a redução e após o bloqueio; e a terceira entre antes do bloqueio e após a redução. Resultados Os grupos do bloqueio de hematoma de fratura e bloqueio supracondilar apresentaram respectivamente os seguintes valores médios: 3.90 (1-10) e 3.50 (-6-10) na diferença 1; 4.35 (-5-10) e 5.00 (-3-10) na diferença 2; e 4.65 (1-10) e 3.80 (-3-10) na diferença 3. Conclusão As duas técnicas se provaram eficientes para analgesia, com discreta superioridade do bloqueio de hematoma, mas sem significância estatística.

A Study of the Medical Record Department’s Experience, Competence, and Application at a Tertiary Care Hospital

Introduction:The primary source of health information for a patient is medical record data. Thus, accurate, complete, and properly recorded patient data are important to provide the best treatment. The workload of the hospital may be reduced and operate more effectively in the hospital if staff members have the necessary knowledge, awareness, and desired clinical abilities, together with an understanding of medical records. Materials and Methods: From January 1 to December 31, 2017, the study was carried out at Tertiary Care Hospital Medical Record Department (MRD). The staff was evaluated for their competency and skill gaps using questionnaires. The complete use of the medical records was then evaluated per quarter for a year. Results: The staff showed adequate understanding of the various questions about medical records. Over the year, there was the highest utilization of files from the MRD, with medicine and obstetrics and gynecology in broad specialties and the department of cardiology with nephrology having the highest utilization in superspecialties. Conclusion: The job environment was pleasant for the staff, and the questionnaire revealed adequate knowledge. Increased satisfaction among MRD staff members, as well as among doctors, nurses, paramedics, and patients, may be related to the utilization being greater in MRD that has been scientifically designed, well‑planned, and appropriately structured, with the best physical amenities

A series of fetal reductions and their outcomes at a tertiary care center in North Karnataka: Fetal reduction series: A boon?

Fetal reduction is a novel method that aims to reduce a higher-order gestation to lower-order pregnancy to reduce both maternal and perinatal adverse outcomes. One of the methods of fetal reduction is by intracardiac injection of KCl under ultrasound guidance. Here, we present a case series ofeight women who had undergone fetal reduction. All of them were trichorionic triamniotic triplets at the time of reduction. In seven women, the reduction was done to twin gestation, whereas one reduction was to singleton pregnancy. Out of eight cases, only one carried to full term and underwent vaginal delivery. One case was lost to follow-up and 2 women underwent expulsion. A total of nine live births were reported with 8 babies going to the neonatal intensive care unit for low birth weight and preterm care. Fetal reduction is an important method that needs to be widely practiced and reported to improve maternal and perinatal outcomes in multifetal gestation.

Materiales y métodos: Investigación cualitativa con diseño fenomenológico que contó con la participación de 10 personas en situación de calle que visitaban diferentes centros de atención en reducción de daños en tres provincias de Costa Rica durante los años de 2019 y 2020. Resultados: La efectivación del derecho a la salud y el reconocimiento de la ciudadanía y la humanidad de las personas en situación de calle consumidoras de sustancias, estuvieron siempre presentes en las experiencias vividas dentro de las instituciones de Reducción de Daños. Además, se explicitó que, los ejes de derechos humanos, cuidados centrados en la persona y el reconocimiento del fenómeno de las drogas como una dimensión perteneciente al ámbito de la Salud Pública fueron puntos neurálgicos "del ser" dentro de la Reducción de Daños en Costa Rica. Conclusión: Una de las mayores contribuciones de este estudio fue la comprensión del progreso de la Reducción de Daños en un no-lugar como la calle. La comprensión fenomenológica social nos mostró también que el sentido de "ser y estar" en el mundo no es algo pasible de ser determinado por estructuras primitivas y punitivas. Por lo tanto, cualquier tentativa de cuidado a la salud que deslegitime al ser humano en cualquier momento o (no) lugar estará destinada al fracaso.

Abstract: Objective: To understand the experiences of Harm Reduction among the voices of homeless people and drug users in Costa Rica. Materials and Methods: A qualitative research with a phenomenological approach that worked with 10 homeless people in Costa Rica during 2019-2020. Results: The materialization of the right to health and the recognition of the citizenship/humanism of homeless people-drug user were always present in the lived experiences of the participants. In addition, it was explicit that the axes of Humanism, Person-centered Care and the recognition of the Drug Phenomenon as a dimension belonging to the field of Public Health were neuralgic points of being within the Harm Reduction in Costa Rica. Conclusion: One of the major contributions of this study was the understanding of the progress of Harm Reduction in a non-place like the street. The social phenomenological understanding also showed us that the sense of "being" in the world is not something that can be determined by primitive and punitive structures. Therefore, any health care attempt that delegitimizes the human being at any time or (no) place will be doomed to failure.

The effect of early radiofrequency turbinate reduction, intranasal steroid, and antihistamine H-1 on persistent allergic rhinitis: a randomized clinical trial

Abstract Objective: We aimed to evaluate the effect of radiofrequency turbinate reduction as an initial treatment on clinical improvement, inflammatory mediators, and remodeling process. Methods: Between July 2018- February 2020, 32 patients with moderate-severe persistent AR were randomly divided into 2 groups. Intervention group received radiofrequency turbinate reduction followed by intranasal steroid and Antihistamine H-1 (AH-1), control group received intranasal steroid and AH-1. Both groups were evaluated for clinical improvement (using visual analogue scale based on total nasal symptoms score, peak nasal inspiratory flow, and turbinate size using imageJ) after 4 and 8 weeks of treatment. Inflammatory mediators (ELISA from nasal secretions was performed to measure ECP, IL-5, and HSP-70) and remodeling markers (nasal biopsy followed by immunohistochemistry examination was performed to evaluate MMP-9, TIMP-1, and PAI-1) were evaluated in week 4. Results: Three patients dropped out of the study, resulting in 16 patients in intervention group and 13 patients in control group. At week 4, clinical response improved significantly in the intervention group compared to control group (Chi-Square test, p<0.05). Compared to control, intervention group experienced a reduction of IL-5 and no significant change in ECP level (Mann Whitney test, p>0.05). Reduction in the ratio of MMP-9/TIMP-1 were significantly higher in intervention group (unpaired t-test, p< 0,05). Meanwhile, increase in HSP-70 in the intervention group was slightly lower than in control group, but the difference with control group was not significant (Mann Whitney test, p>0.05). Conclusion: Early radiofrequency turbinate reduction followed by pharmacotherapy given to persistent moderate-severe AR patients give more improvement only in early clinical symptoms and reduce MMP-9/TIMP-1 ratio, thus it might be suggested as one of the adjuvant therapies for the management of moderate-severe persistent AR. However, further investigation with a larger sample size and longer follow-up period is needed. Level of evidence: 1B.

Effect of combination treatment of protocatechuic acid with 5-fluorouracil and oxaliplatin on colon cancer Caco-2 cell line

Among the most common antitumor drugs used in the treatment of colon cancer are 5-fluorouracil and oxaliplatin (5-FU and OXA). However, both these drugs have many side effects, and hence there is a need for new treatment\approach to reduce the side effects aas well as drug concentration. In this context, here, we investigated the effect of addition of protocatechuic acid (PCA) onto either monotherapies or combination therapies of 5-FU and OXA on the human colon cancer (Caco-2) cell line. In addition, we did evaluate the synergistic effect of PCA with 5-FU and OXA. Further, we determined the suppressive effects of different doses of PCA alone or in combination with 5-FU/OXA on cell proliferation after 24 and 48 hours. We identified a suppressive effect of PCA on cell viability at 48 h starting from the dose of 50 µM Matrix metalloproteinase-2 (MMP-2) and MMP-9 gene expression levels and apoptotic effects showed significant increases and decreases depending on the dose and time applied in the experimental groups. The highest synergistic activity was seen at 2:1 concentration of 5-FU+ PCA. Our findings indicate the presence of the cytotoxic and apoptotic effects of PCA in Caco-2 cells at 48 h, increasing with a dose- and time-dependent manner.

Consultório de Rua: cuidado no território na interface entre HIV/Aids, drogas e Redução de Danos / 'Street Outreach Teams': care in the territory at the interface between HIV/AIDS, drugs and Harm Reduction

RESUMO Este artigo teve como objetivo apresentar a experiência da implementação dos Consultórios de Rua na cidade do Recife-PE como estratégia de prevenção ao HIV/Aids e Redução de Danos (RD) decorrentes do uso de álcool, crack e outras drogas. Ainda que o resgate da história desse processo apresente tensões, impermanências e alternâncias nos modelos de cuidado implementados pela gestão municipal, sua análise aponta a importância de reafirmar, no contexto atual, a proposição de práticas e experiências nesse campo, ancoradas na RD e na defesa da cidadania e dos direitos humanos. Observa-se que os Consultórios de Rua contribuem para fortalecer a prática de RD no Sistema Único de Saúde (SUS) como estratégia de saúde pública, assim como reduzem as vulnerabilidades às Infecções Sexualmente Transmissíveis (IST) e Aids associadas ao uso de álcool, crack e outras drogas. A experiência do CR ampliou a promoção à linha de cuidado para pessoas que usam álcool, crack, e outras drogas, reduzindo também as vulnerabilidades das IST/Aids associadas a esse consumo. No entanto, vê-se que é preciso investir e manter processos formativos que sejam permanentes, além de estudos e pesquisas epidemiológicas que demonstrem os resultados alcançados nos diferentes contextos.

ABSTRACT This article aims to present the experience of implementing 'Street Outreach Teams' in the city of Recife-PE as a strategy for HIV/AIDS prevention and Harm Reduction (HR) associated with the use of alcohol, crack, and other drugs. Although the review of the history of this process reveals tensions, volatility, and alternations in the care models implemented by the city management, the analysis points out the importance of reaffirming, in the current context, the practices and experiences in that field, anchored in HR and in the defense of civil and human rights. Street outreach teams have been found to help strengthen the practice of HR in the Unified Health System, as a public health strategy to reduce vulnerabilities to Sexually Transmitted Infections (STI) and AIDS associated with the use of alcohol, crack, and other drugs. The experience has expanded the promotion of the line of care for people who use alcohol, crack, and other drugs and reduced the vulnerabilities of STI/AIDS associated with such use. However, it seems that it is necessary to invest and maintain permanent training processes, in addition to epidemiological studies and research demonstrating the results achieved in different contexts.
