Leprosy Skin Lesion Detection: An AI Approach Using Few Shot Learning in a Small Clinical Dataset

This is an exploratory research study to check if artificial intelligence (AI) based image marker tool can aid leprosy screening to detect leprosy cases early in field situation and reduce the financial and personnel burden. We aimed to collect clinical leprosy skin lesion images and develop an AI model to identify and differentiate them. A total of 368 clinically diagnosed leprosy and 28 non-leprosy skin lesions were collected by an expert leprologist from 151 eligible patients using a multimodal imaging protocol. A Siamese-based Few Shot Learning (FSL) model was trained as it is a meta learning approach on an extremely small data set with fewer disease classes (disease conditions as categories). The number of class labels were increased by fine-grained grouping of skin lesions based on skin morphology (Nine leprosy subgroups) and further divided into train-set and test-set. An AI model was successfully developed, and the results indicated an accuracy of 91.25% and 73.12% on train-set and test-set for two-way one-shot task, respectively. The best sensitivity-specificity for the test-set were 72.39%-73.66% (two-way one-shot task). This early research data indicates that the development of AI based leprosy screening application is feasible using the skin lesion image as marker. The FSL method was successfully used in this training the small data set. However, this is a small sample size study, and more leprosy cases need to be enrolled along with an equal number of non- leprosy cases while improving model architecture to reduce overfit or bias problem. Moreover, as of now this tool cannot be used for neural leprosy (having no skin lesion) as well as lepromatous leprosy having diffuse infiltration. This tool will need further development and validation on pictures taken by different categories of common health care workers using available mobile phones.

OBJECTIVE@#To conduct anatomical study on the iliac crest chimeric tissue flap and summarize its effectiveness of clinical application in repairing limb wounds.@*METHODS@#Latex perfusion and anatomical study were performed on 6 fresh adult cadaver specimens with 12 sides, to observe the initial location, distribution, quantity, and direction of the common circumflexa iliac artery, the deep circumflexa iliac artery, and the superficial circumflexa iliac artery, and to measure their initial external diameter. Between December 2020 and September 2022, the iliac crest chimeric tissue flap repair was performed on 5 patients with soft tissue of limbs and bone defects. There were 3 males and 2 females, with an average age of 46 years (range, 23-60 years). Among them, there were 3 cases of radii and skin soft tissue defects and 2 cases of tibia and skin soft tissue defects. The length of bone defects was 4-8 cm and the area of skin soft tissue defects ranged from 9 cm×5 cm to 15 cm×6 cm. The length of the iliac flap was 4-8 cm and the area of skin flap ranged from 12.0 cm×5.5 cm to 16.0 cm×8.0 cm. The donor sites were directly sutured.@*RESULTS@#Anatomical studies showed that there were 10 common circumflex iliac arteries in 5 specimens, which originated from the lateral or posterolateral side of the transition between the external iliac artery and the femoral artery, with a length of 1.2-1.6 cm and an initial external diameter of 0.8-1.4 mm. In 1 specimen without common circumflexa iliac artery, the superficial and deep circumflex iliac arteries originated from the external iliac artery and the femoral artery, respectively, while the rest originated from the common circumflex iliac artery. The length of superficial circumflex iliac artery was 4.6-6.7 cm, and the initial external diameter was 0.4-0.8 mm. There were 3-6 perforator vessels along the way. The length of deep circumflex iliac artery was 7.8-9.2 cm, and the initial external diameter was 0.5-0.7 mm. There were 3-5 muscular branches, 4-6 periosteal branches, and 2-3 musculocutaneous branches along the way. Based on the anatomical observation results, all iliac crest chimeric tissue flaps were successfully resected and survived after operation. The wounds at recipient and donor sites healed by first intention. All patients were followed up 8-24 months, with an average of 12 months. The tissue flap has good appearance and soft texture. X-ray film reexamination showed that all the osteotomy healed, and no obvious bone resorption was observed during follow-up.@*CONCLUSION@#The common circumflex iliac artery, deep circumflex iliac artery, and superficial circumflex iliac artery were anatomically constant, and it was safe and reliable to use iliac crest chimeric tissue flap in repairing the soft tissue and bone defects of limbs.

Applied anatomy of recurrent branch of median nerve and microsurgical treatment of its compression syndrome / 中华显微外科杂志

Objective:To observe the anatomy of the recurrent branch of median nerve, summarize the injury mechanism of the recurrent branch of median nerve, and explore the surgical method and clinical effect of the compression.Methods:From February 2018 to October 2021, 12 fresh hand specimens were used in Department of Hand Surgery in the Second Hospital of Tangshan, including 6 male specimens, 3 left and 3 right hands, and 6 female specimens, 3 left and 3 right hands. Anatomy of the recurrent branch of median nerve and observation of its location, measurement of the length of each muscle branch innervating thenar muscle and the easy-to-jam position of the recurrent branch of median nerve in the course of running. The measurement results uses nonparametric test of statistical analysis by side and gender. P<0.05 was considered statistically significant. From January 2020 to January 2022, 21 patients with entrapment of the recurrent median nerve of wrist were treated, 14 males and 7 females. The age ranged from 31 to 65 years old, with an average of 46.2 years old. All patients developed thenar muscular atrophy. Before operation, the recurrent branch of median nerve was marked into the muscle point, and the thenar projection on palm surface was pressed, which caused fatigue and soreness. Electromyography examination: the motor latency of median nerve endings was more than 4.5 ms, and both fibrillation potential and positive potential appeared. The motor conduction velocity of all patients was less than 30 m/s, and the motor nerve amplitude was less than 10 mV. Surgical exploration of the recurrent branch of median nerve revealed that the trunk of the recurrent branch of median nerve made the tendon arch thickened at the starting point of the superficial head of flexor pollicis brevis, and there was compression between the deep layer of the palmar aponeurosis and the thenar musculocutaneous membrane, which was completely released during the operation to relieve the compression factor. All 21 patients had followed-up in outpatient. Results:Distance from the origin of the recurrent branch of median nerve to the distal edge of transverse carpal ligament. The distance from the origin of the recurrent branch of median nerve to the distal edge of transverse carpal ligament were (0.30, 0.31, 0.32) cm and (0.31, 0.32, 0.32) cm in male left and right groups, respectively, with no statistical significance ( Z=-0.943, P=0.346); The female left and right groups were (0.28, 0.28, 0.28) cm and (0.29, 0.30, 0.30) cm, respectively, and the difference was statistically significant ( Z=-2.121, P=0.034). The length and transverse diameter of the trunk of the recurrent branch of the median nerve, the length of the superficial head branch of flexor pollicis brevis and the length of the palmar muscle branch of the thumb had no significant difference between the left and right sides of males and females( P > 0.05). The length of abductor pollicis brevis muscle branch: the male left and right groups were (1.45, 1.27, 1.31) cm and (1.54, 1.38, 1.47) cm, respectively, and there was no statistical difference ( Z=-1.528, P = 0.127); The female left and right groups were (1.21, 1.18, 1.15) cm and (1.25, 1.24, 1.25) cm respectively, and the difference was statistically significant ( Z=-1.993, P=0.046). All the 21 patients were entered in follow-up for 9-24 (average 15) months. After operation, the wounds of all patients healed in the first stage, the soreness at thenar disappeared, and the thenar muscle was full in appearance. In 21 patients, the thumb abduction function returned to normal, the thumb to palm opposition returned to normal in 19 cases, and was slightly limited in 2 cases. After operation, thenar muscle strength recovered to grade 5 in 19 cases and grade 4 in 2 cases. At the last follow-up, electromyography showed that the motor latency of median nerve endings was less than 4.5 ms, and the motor conduction velocity was greater than 40 m/s; Motor nerve amplitudes were all greater than 10 mV. According to the functional evaluation standard of carpal tunnel syndrome recommended by Gu Yudong, 19 cases were excellent, 2 cases were good, and the excellent and good rate was 100%. Conclusion:The length of each nerve branch of the recurrent median nerve innervates thenar muscle is different, and there are many factors that cause the recurrent median nerve to get stuck. It is of high clinical value to master the anatomical structure of the recurrent median nerve and the mechanism of the entrapment, and to completely loosen vulnerable parts by surgery.

Objective:To investigate the anatomy of rectus femoris muscle flap and the anterolateral thigh muscle flap and their clinical application in reconstruction of large soft tissue defects after the removal of oral malignant tumour.Methods:From December 2006 to June 2009, 8 specimens of Chinese adult cadavers fixed in 10% formaldehyde were dissected to perform anatomy of anterolateral thigh region at the School of Basic Medical Sciences, Kunming Medical University. Anatomical images were analysed using Image-Pro Plus 6.0. Then, a retrospective study was performed on 19 patients who had postoperative defects after oral malignant tumour surgery and the defects were reconstructed with the rectus femoris muscle flap and the anterolateral thigh muscle flap from March 2020 to July 2022 at the Department of Oral and Maxillofacial Surgery, Affiliated Stomatology Hospital, Kunming Medical University. The postoperative defects of the 19 patients ranged from 3.0 cm×6.0 cm to 5.0 cm×10.0 cm. Ten rectus femoris muscle flaps, 8 anterolateral thigh muscle flaps and 1 combined rectus femoris muscle flap and anterolateral thigh muscle flap were used. The muscular flaps sized from 4.0 cm × 8.0 cm to 6.0 cm × 11.0 cm. Regular postoperative outpatient follow-ups were conducted.Results:The lengths of vessels of the harvested rectus femoris muscle flap and anterolateral thigh muscle flap were 63.4 mm± 12.9 mm and 112.5 mm± 19.6 mm, respectively. The starting outer diameters of the lateral circumflex thigh artery, the oblique branch of the lateral circumflex thigh artery and the descending branch of the lateral circumflex thigh artery were 2.92 mm±0.72 mm, 1.88 mm±0.23 mm and 2.29 mm±0.43 mm, respectively. Postoperative follow-up lasted for 7 to 32 months, with 17.5 months in average. Seventeen flaps were completely survived and the rectus femoris muscle flap was completely mucosalised 5 weeks after surgery. However, 2 rectus femoris muscle flaps had necrosis of which one was changed to a tongue flap reconstruction and the other encountered flap necrosis during postoperative radiotherapy and healed after debridement and dressing changes. There was no postoperative complication in the donor sites. Other than the 2 patients, all other 17 patients had satisfactory clinical outcomes.Conclusion:Both of the starting outer diameters and length of vessels of the femoris muscle flap and the anterolateral thigh muscle flap meet the requirements for reconstruction of maxillofacial defects, and both muscular flaps are simple to prepare, in good reconstructive results with few complication, as well as an excellent outcome. They are feasible approaches for reconstruction of large soft tissue defects left after the removal of an oral malignant tumour.

Observation and clinical significance of skin in the first web space / 中华显微外科杂志

Objective:To scientifically measure and morphologically evaluate the anatomical shape of the skin in the first web space based on cadavers, and to guide the design of flap in this area.Methods:Sixteen human cadavers fixed with 10% formaldehyde without injury or deformity on the hand were selected in the Department of Hand Surgery, the Third Hospital of Suqian. According to the characteristics of the first web area, marker points were selected for measurement and morphological observation. Morphological characteristics of the first web with thumb radial abduction(r) or palmar abduction(p) were measured and compared. The t-test was used for statistical analysis. P<0.05 was considered statistically significant. According to the results of measurement, standardised shapes and parameters of the skin were obtained for flap repair of defect of the first web. Results:When the thumb was in palmar abduction, the maximum distance [a(p)] of the first web of female(F) and male(M) was 5.78/8.42 cm(F/M), and the skin [S(p)] was 17.09/23.63 cm 2(F/M), both were significantly greater than the distance [a(r)] at 4.86/6.28 cm and the area of skin area [S(r)] at 14.39/20.15 cm 2 when thumb was in the radial abduction position( P<0.05). There was no significant difference in the length of [b(r)] and [b(p)] alone the long axis of flap between palmar and radial abductions(7.54/9.38 cm and 7.34/9.74 cm, respectively) of the thumb( P>0.05). It was found that the area of first web was not shaped as a symmetrical spindle, but an irregular quadrilateral inclined to the index finger. Conclusion:Design and measurement of a flap for the first web space should take the maximum palmar abduction of a thumb as a reference. The asymmetric quadrilateral flap design is more in line with the anatomical and characteristics in the region.

Anatomy of the perforator propeller flap of superior lateral genicular artery and its clinical application in repair of soft tissue defect of anterolateral knee / 中华显微外科杂志

Objective:To study the anatomy of the perforator propeller flap of superior lateral genicular artery, and to explore a surgical method and clinical application in repair of the soft tissue defect of anterolateral knee with the flap.Methods:From September 2019 to September 2021, 8 knees of 4 chilled fresh specimen of adults were studied. The perforators of the superior lateral genicular artery were observed. The length, outer diameter of the perforators, and the locations of the skin perforation were recorded. The superior lateral genicular artery perforator propeller flaps were then applied clinically to 5 patients(3 males and 2 females) with soft tissue defects of anterolateral knee. Two of the patients had combined ligament injury and(or) bone joint exposure. The age of patients ranged from 25 to 48 years old, at 33.4 years old in average. The sizes of soft tissue defects ranged from 4.0 cm×4.0 cm to 8.0 cm×5.0 cm. The sizes of perforator propeller flaps of superior lateral genicular artery were 10.0 cm×5.0 cm to 13.0 cm×6.0 cm. The superior perforating vessels of the superior lateral genicular artery were found and marked at the points of skin perforation. Preoperative contrast-enhanced ultrasound were performed to confirm the dominant perforating vessels and had the skin perforating points marked. Intraoperative CDU were further performed to confirm the points of dominant perforating vessels. Perforator propeller flaps were designed depending on the size of the anterolateral soft tissue defect, and flaps were prepared and transferred to the defect sites. Postoperative follow-ups were conducted at outpatient clinic. The survival of the flap and knee function were observed according to the Bai-ly knee scoring.Results:The anatomy showed that an average pedicle length of the superior lateral genicular artery perforator was(8.2±0.9) cm, with an average starting outer diameter at(1.1±0.2) mm. All 5 flaps survived during the follow-up that lasted for 10 to 24 months, with an average of 15.3 months. All flaps healed in 2 weeks after surgery without complications such as soft tissue infection, bone and joint infection were observed. At the last follow-up, no obvious bloated appearance of the flaps were observed. The colour and elasticity of the flaps were similar to the surrounding skin. The knee function was assessed: 4 patients were in excellent and 1 in good. The range of knee flexion and extension was from 100° to 150°. The patients were satisfied with the appearance and function of the knees.Conclusion:The size of the perforator of superior lateral genicular artery and the pedicle length are ideal. The propeller flap can be used to repair the soft tissue defect around the anterolateral knee, with satisfactory functional recovery of a knee. It is a good method to repair the soft tissue defect around anterolateral knee.

3D printed guide plate assisted and C-arm X-ray fluoroscopic positioning for femoral tunnel reconstruction of medial patellofemoral ligament in treating recurrent patellofemoral dislocation: a comparison of efficacies / 中华创伤杂志

Objective:To compare the efficacies of 3D printed guide plate assisted positioning and C-arm X-ray machine fluoroscopic positioning for femoral tunnel reconstruction of medial patellofemoral ligament in treating recurrent patellofemoral dislocation.Methods:A retrospective cohort study was performed on the clinical data of 60 patients with recurrent patellar dislocation admitted to the First Affiliated Hospital of Kunming Medical University from January 2018 to December 2022. The patients included 29 males and 31 females, with age range of 14-40 years [(28.6±7.6)years]. The 3D printed guide plate was used to locate the femoral tunnel in 30 patients for medial patellofemoral ligament reconstruction (3D guide group), and C-arm X-ray machine was used for another 30 patients (conventional group). (1) CT data of the knee joint were collected before surgery and at 7 days after surgery. Mimics 19.0 software was introduced to measure the distance between the center of femoral tunnel and Sch?ttle point after surgery. (2) Knee Lysholm score and Kujala score were used to evaluate the knee function before and at 3, 6, 9 and 12 months after surgery. (3) At the same time points, Opti-Knee TM 3D knee kinematics analysis system was used to collect the forward and backward displacement, up and down displacement, internal and external displacement, internal and external flipping angle, internal and external rotation angle, and flexion and extension angle of the affected knee joint. The range of each freedom degree was calculated and 6 freedom degree items of 30 healthy people were subjected to knee kinematics analysis. Results:All patients were followed up for 12-15 months [(12.3±0.7)months]. (1) The distance between the center of femoral tunnel and Sch?ttle point in the 3D guide group was (5.5±2.3)mm, smaller than that in the conventional group [(7.6±2.5)mm] ( P<0.01). (2) The Lysholm score and Kujala score of the 3D guide group and conventional gruop gradually increased after surgery (all P<0.01). There were no significant differences in the Lysholm score or Kujala score between the 3D guide group and conventional gruop before surgery and at 12 months after surgery (all P>0.05). At 3, 6 and 9 months after surgery, the Lysholm score of the 3D guide group [(70.4±4.5)points, (86.4±3.1)points, (91.2±3.2)points] and Kujala score [(74.2±5.3)points, (80.9±3.5)points, (85.2±3.2)points] were higher than those of the conventional group [Lysholm score: (67.3±5.2)points, (81.8±2.5)points, (86.2±1.9)points; Kujala score: (69.8±5.2)points, (77.6±2.1)points, (82.7±2.6)points] ( P<0.05 or 0.01). (3) Before surgery, the forward and backward displacement in the 3D guide group and conventional group [(0.6±0.1)cm, (0.6±0.2)cm], up and down displacement [(0.5±0.1)cm, (0.6±0.0)cm], internal and external displacement [(0.7±0.1)cm, (0.6±0.2)cm], and flexion and extension angle [(50.6±10.3)°, (51.6±8.5)°] were less than those in the healthy controls [(1.6±0.3)cm, (1.7±0.5)cm, (1.0±0.4)cm, (63.2±5.1)°] (all P<0.05), while the internal and external flipping angle [(17.5±4.0)°, (17.1±3.8)°] and internal and external rotation angle [(17.9±1.9)°, (17.5±1.5)°] were greater than those in the healthy controls [(11.8±3.6)°, (15.8±4.9)°] (all P<0.05). At other time points, the results of front and back displacement, up and down displacement, internal and external displacement, internal and external rotation angle in the 3D guide group and conventional group were not significantly different compared with the healthy controls (all P>0.05). The flexion and extension angle in the 3D guide group and conventional gruop were smaller than those in the healthy controls at 3 months after surgery (all P<0.05). At 6 and 9 months after surgery, the flexion and extension angle in the conventional group [(55.0±3.7)°, (57.7±4.8)°] were smaller than those in the healthy controls [(63.2±5.1)°, (63.2±5.1)°] (all P<0.05), but no significant difference was found between the 3D guide group [(61.0±4.8)°, (61.8±4.9)°] and the healthy controls (all P>0.05). The flexion and extension angle in the 3D guide group and conventional gruop was similar with that in the healthy controls at 12 months after surgery (all P>0.05). Conclusions:Compared with the C-arm X-ray machine, the 3D printed guide plate assisted positioning of femoral tunnel is more simple and accurate for the medial patellofemoral ligament reconstruction in treating recurrent patellofemoral dislocation, together with better early knee function recovery, better satisfaction of the patients, and better and faster restoration of the flexion and extension angle of knee joint kinematic function.

Effect of applied muscle tension on improving vasovagal reactions among blood donors: a meta-analysis / 中国输血杂志

【Objective】 To systematically evaluate the effect of applied muscle tension (AMT) exercises on reducing vasovagal reactions(VVRs) among blood donors by meta-analysis. 【Methods】 Nine related databases including MEDLINE, Web of Science and CINAHL were searched using "applied muscle tension" and "vasovagal reactions" as keywords to collect clinical studies on the effects of AMT exercise on VVRs during blood donation. Two researchers independently screened, evaluated the quality and extracted data from the retrieved literature according to the inclusion and exclusion criteria. RevMan 5.4 was used to conduct meta-analysis on the extracted data. 【Results】 A total of 7 articles were finally included, 5 in English and 2 in Chinese, covering 6 808 blood donors. The experimental group performed AMT during blood donation, while the control group did not. Compared with the control group, the difference in reducing the incidence of VVRs [ RR = 0.60, 95%CI (0.42, 0.87), P<0.01] was statistically significant in the AMT group. 【Conclusion】 AMT can effectively reduce the incidence of VVRs during blood donation. However, due to the limitation in the included studies, high-quality studies with perspectiveness, multicenter, large-sample size are further needed for validation in the future.

Efeito de um pacote de ensino sobre o desempenho de cuidadoras no treino de ocupações para crianças com TEA / Effect of a teaching package on the performance of caregivers in occupation training for children with ASD

Resumo Introdução As limitações funcionais observadas na pessoa com Transtorno do Espectro Autista (TEA) podem impedir a participação independente em ambientes comunitários. A aprendizagem de atividades cotidianas pode aumentar a participação inclusiva e a qualidade de vida dessas pessoas. Estratégias de ensino via profissional estão descritas na literatura, enquanto o ensino via cuidador para essas habilidades precisa ser explorado e torna-se essencial ao se considerar que o aumento de crianças com TEA não é acompanhado pelo aumento proporcional de profissionais qualificados, além de que os pais lidam diretamente com ensino dessas atividades. Objetivo Elaborar e avaliar a aplicação de um pacote de treinamento para cuidadores de crianças com TEA, para o ensino de preparo de sanduíche e escovação de dentes. Método Participaram quatro cuidadoras. O pacote de ensino incluiu Videomodelação Instrucional, Automonitoramento, Feedback Atrasado e imediato. Adotou-se o critério de precisão de desempenho igual ou superior a 90% por duas sessões consecutivas. Resultados Todas as cuidadoras apresentaram aumento na precisão de desempenho após exposição aos componentes do pacote de treinamento. Uma cuidadora atingiu critério de precisão passando por apenas um componente ou pela combinação deles. Três cuidadoras precisaram passar necessariamente pela combinação dos componentes e pelas fases de feedback para atingir o critério. Conclusão Corroborando outros estudos, não houve diferença significativa nos desempenhos das cuidadoras quando se comparou os componentes. Assim como estudos anteriores, demonstra-se que as fases de feedback desempenharam um papel importante para o alcance do critério. Atesta-se que o pacote de treinamento foi satisfatório no ensino das cuidadoras.

Abstract Introduction The functional limitations observed in people with Autistic Spectrum Disorder (ASD) may prevent independent participation in community settings. Learning everyday activities can increase the inclusive participation and quality of life of these people. Teaching strategies via professionals are described in the literature, while teaching via caregivers for these skills needs to be explored and becomes essential when considering that the increase in children with ASD is not accompanied by a proportional increase in qualified professionals, in addition to the fact that the parents deal directly with teaching these activities. Objective To elaborate and evaluate the application of a training package for caregivers of children with ASD, for teaching sandwich preparation and toothbrushing. Method Four caregivers participated. The teaching package included Instructional Video Modeling, Self-Monitoring, Delayed and Immediate Feedback. A performance accuracy criterion equal to or greater than 90% was adopted for two consecutive sessions. Results All caregivers showed an increase in performance accuracy after exposure to the training package components. One caregiver reached the accuracy criterion by going through just one component or a combination of them. Three caregivers necessarily needed to go through the combination of components and the feedback phases to reach the criterion. Conclusion Corroborating other studies, there was no significant difference in the performance of caregivers when comparing the components. As with previous studies, it is shown that the feedback phases played an important role in achieving the criterion. It is attested that the training package was satisfactory in teaching the caregivers.

Estas invenciones pueden ser evaluadas, estimuladas, guiadas o refutadas por profesionales de la salud.

Abstract Objective To describe the technological inventions developed by family caregivers from the perspective of home care professionals, discussing them in the light of the care needs at home. Method qualitative, multicenter research, supported by the theoretical model of the Basic Human Needs of Wanda Horta. The data were obtained from interviews with 52 professionals from Home Care teams in four municipalities of Minas Gerais, which were submitted to Content Analysis. Results were identified 27 inventions created by caregivers with materials/resources existing at home. Most of the inventions were motivated by the psychobiological needs of movement, positioning, protection and comfort, feeding, physiological eliminations, hygiene and drug therapy. Other inventions were motivated by psychosocial and psychospiritual needs to improve communication between caregiver and family member, provide leisure, distraction, and spiritual comfort. Conclusions/Implications for practice the processes of invention of caregivers show reflective awareness by articulating, unsystematically and intuitively, existing resources and objects at home, generating strategies or products similar to existing technologies. These inventions can be evaluated, stimulated, guided or refuted by health professionals involved in home care on a daily basis.

Is a diet of Planococcus citri nymphs and adults suitable for Chrysoperla externa for use in biological control?

ABSTRACT Several studies have shown that the survival and reproduction of lacewings varies depending on the type of prey they consumed, especially during the first instar. In this study, we evaluated the effect of a diet consisting of Ephestia kuehniella (EK) and/or Planococcus-citri (PC) eggs offered to first instar Chrysoperla externa on subsequent development and survival. Larvae supplied only with P. citri (PC) nymphs had extended immature development, low survival, adults with lower weight and longevity, low fecundity and egg viability, and lower net reproduction rate (R0). Larvae submitted to the treatment EK+PC responded positively to the diet, showing results similar to those obtained in the control-EK treatment. Therefore, this mealybug supports suitable development and reproduction of C. externa when it is provided to second instar larvae after they fed on E. kuehniella eggs as first instars. As far as we know, this is the first report that demonstrates the effect of natural prey and alternatives on different larval stages of lacewings. This information is valuable in developing protocols for use of C. externaas a pest control agent.

Territorio y minera: la necesidad de precisar un enfoque para su abordaje

Las actividades sobre el planeta cambian y también la forma de observarlas, pero frente a la cantidad de situaciones que se circunscriben alrededor de las actividades extractivas, es conveniente, para todas las partes implicadas, buscar una mayor precisión en el enfoque sobre estos asuntos complejos; por eso, el objetivo de este escrito es aportar ideas, para ajustar el enfoque territorial de la actividad minera, con miras al desarrollo sostenible. Para ello, se utilizó una metodología aplicada a un caso real en Colombia, que permite expresar un enfoque combinado, en el cual, el espacio responde al dónde; la actividad minera representa el qué; la gradualidad del tiempo define el cuándo y, el desarrollo sostenible, proyectado en conjunto con los actores, define el para qué. Se logró una ubicación y, a la vez, representación multiescalar, a través de una región de influencia minera. Para mostrar interrelaciones, se realizó una caracterización minera sobre esos cuatro aspectos esenciales: lugar, actividad, tiempo y objetivo. También, se definió una trayectoria multitemporal para la gradualidad de las acciones en el tiempo y, desde la perspectiva comunitaria, se llevó a cabo la integración de propuestas organizadas en cuatro conjuntos. Se concluye que, para una minería más justa y mejor, nos conviene ampliar el radio de observación, considerar el pasado, presente y futuro y mirar desde la óptica de otros. Esto significa, cambiar las perspectivas, trazar nuevos horizontes e integrar acciones hacia objetivos comunes, que minimicen conflictos y potencien oportunidades más equitativas en las relaciones socioambientales.

Activities on our planet change, as does the way of observing them. But in the face of the number of situations that are circumscribed around extractive activities, it is convenient for all parties involved, to seek greater precision in the approach to these complex issues; therefore, that is why the purpose of this text is to provide ideas, so as to adjust the territorial approach of the mining activity, leading to sustainable development. To do this a methodology was applied to a real case in Colombia, where space pertains to the location; mining activity represents the purpose; the gradual progression of time defines when, and sustainable development projects are the goal. A multi-location and representation were achieved, a mining characterization on four essential aspects to show interrelatios, as well as a multi-temporal trajectory for the gradual progression of actions over time, and, from the community perspective, the integration of proposals in four sets. It is concluded that, for fairer and better mining, it is convenient for us to expand the radius of observation, to consider the past, present and future, adopts others viewpoints. This means changing perspectives, drawing new horizons and integrating actions towards common objectives that minimize conflicts and enhance more equitable opportunities in socio-environmental relations.

Simulación y optimización de sistemas de vacunación con capacidad finita / Simulation and optimization of systems vaccination with finite capacity

Resumen Objetivo: Caracterizar y optimizar el flujo de pacientes dentro de un centro de vacunación, para los casos donde debe tomarse en cuenta que existe una capacidad finita en las colas frente a las estaciones. Materiales y Métodos: Se asume que los sistemas de vacunación se comportan como una red cerrada de colas con capacidad finita; para caracterizar el flujo de pacientes, se aplica simulación y un diseño experimental Box-Bhenken, donde las variables son las capacidades en las colas (buffer); posteriormente se obtienen los metamodelos del tiempo de ciclo y del número de pacientes vacunados, finalmente se calcula la asignación óptima de los lugares en las colas aplicando programación matemática. Resultados: Las colas de llenado de formatos, entrega de información y vacunación son las de mayor efecto sobre el tiempo de estadía; las colas de vacunación y el Triage son las de mayor efecto sobre la cantidad de pacientes vacunados.Si se maximiza la salida de pacientes, la mayor cantidad de lugares deben asignarse a la estación de vacunación y el resto de los espacios se distribuyen en las demás estaciones; por otra parte, si se minimiza el tiempo de estadía, entonces la mayor parte de los lugares se asignan a la estación Triage y a continuación a la estación de Vacunación, el resto de los espacios se asignarán dependiendo de la capacidad total del sistema. Conclusiones: Los responsables de administrar esta clase de sistemas deben definir el criterio bajo el cual deben cuantificar el desempeño del sistema de vacunación y a partir de este, gestionar y controlar el proceso. Cuando la demanda supera las expectativas y no es viable incrementar la capacidad, entonces la alternativa es optimizar el flujo controlando la cantidad de personas dentro del sistema.

Abstract Objective: Characterize and optimize the flow of patients within a vaccination center, for cases where it must be consider that there is a finite capacity in the queues in front of the stations. Materials and Methods: Vaccination systems are assumed to behave as a closed queue network with finite capacity; To characterize the flow of patients, simulation and a Box-Bhenken experimental design are applied, where the variables are the capacities in the queues (buffer); Subsequently, the metamodels of the cycle time and the number of vaccinated patients are obtained. Finally, the optimal allocation of places in the queues is calculated by applying mathematical programming. Results: The queues for filling out forms, delivery of information and vaccination are the ones with the greatest effect on the length of stay; the vaccination and triage queues have the greatest effect on the number of vaccinated patients. If the output of patients is maximized, the greatest number of places should be assigned to the vaccination station and the rest of the spaces are distributed in the other stations; On the other hand, if the length of stay is minimized, then most of the places are assigned to the Triage station and then to the Vaccination station, the rest of the spaces will be assigned depending on the total capacity of the system. Conclusions: Those responsible for managing this class of systems must define the criteria under which they must quantify the performance of the vaccination system and, based on this, manage and control the process. When demand exceeds expectations and increasing capacity is not feasible, then the alternative is to optimize flow by controlling the number of people within the system.

Capacitação de cuidadores de crianças com autismo em intervenção via SUS / FORMACIÓN DE CUIDADORES DE NIÑOS CON AUTISMO EN INTERVENCIÓN VÍA SUS / TRAINING OF CAREGIVERS OF AUTISTIC CHILDREN IN INTERVENTION VIA SUS

Autism spectrum disorders are characterized by neurodevelopmental alterations with onset of symptoms in childhood. The literature has indicated that the models of intensive behavioral intervention can produce significant improvements in several areas of the development of people with this diagnosis. The offer of this type of therapy in Brazil is still scarce, especially in institutions financed by the Unified Health System. However, the training of caregivers has been pointed out as an alternative to promote access to this type of therapy to more autistic people. The aim of this study was to analyze the effects of caregiver training on the development of autistic children treated at an institution financed by the Unified Health System. Participants were assessed before and after the intervention, using an instrument that measured the children's development. The results indicated improvement in the development of six children out of a group of 17.

Os transtornos do espectro do autismo constituem-se por alterações do neurodesenvolvimento com início dos sintomas na infância. A literatura tem indicado que os modelos de intervenção comportamental in-tensiva podem produzir melhoras significativas em várias áreas do desenvolvimento de pessoas com esse diagnóstico. A oferta desse tipo de terapia no Brasil ainda é escassa, especialmente em instituições finan-ciadas pelo Sistema Único de Saúde. Contudo, a capacitação de cuidadores tem sido apontada como uma alternativa para promover o acesso a esse tipo de terapia a mais pessoas com autismo. O objetivo deste estudo foi analisar os efeitos da capacitação de cuidadores no desenvolvimento de crianças com autismo atendidas em uma instituição financiada pelo Sistema Único de Saúde. Os participantes foram avaliados antes e após a intervenção, por meio de instrumento que mediu o desenvolvimento das crianças. Os resul-tados indicaram melhora no desenvolvimento de seis crianças de um grupo de 17.

Contingency Analysis of Ethics Training in Psychology Programs in Colombia / Análisis contingencial de la formación ética en programas de psicología en Colombia / Análise de contingência da formação ética em programas de psicologia na Colômbia

Introduction. The topic of ethics training in psychology has been constant in Colombia, especially since the Colombian Association of Psychology Faculties was created. However, reports of deficiencies in ethics training and research reviews, centered on identifying the ethical knowledge of students and professional actions in psychology, justify more complex studies. In this framework, relationships between contextual factors, which are necessary to understand the dynamics of psychological education, and factors related to ethically practicing the profession, must be included in the analysis. The objective of the study was, therefore, to demonstrate interdependent relations between the different actors that participate in ethics training, the interlocking of individual reinforcement contingencies and cultural consequences through a contingency analysis of psychology program curricula in Colombia. Methodology. A qualitative documentary análisis study with the methodology proposed by Todorov in terms of contingency analyses. Results. Interlocking practices were demonstrated in terms of metacontingencies in educational institutions, more focused on professional development than on ethics training. On an inter-institutional level, practices do not demonstrate a metacontingency in the strict sense, which was analyzed in light of the university autonomy and academic freedom policy. Malpractice can be considered a macrocontingency from the point of view of normalizing practices without an ethical reflection. Discussion. Psychological education is understood as a cultural practice that depends on relatively effectively interlocking contingencies, which prepares professionals who can adjust to the needs of society. This posture is coherent with the authors' proposals. Conclusions. It is necessary to effectively integrate training in disciplinary skills with ethics, in order to attain a cultural practice in the terms of the analyzed metacontingency.

Introducción. El tema de la formación ética en psicología ha sido una constante en Colombia, especialmente desde la constitución de la Asociación Colombiana de Facultades de Psicología. Sin embargo, los reportes de deficiencias en la formación ética y la revisión de investigaciones, centradas en identificar el conocimiento ético de los estudiantes y el actuar profesional en psicología, justifican un estudio más complejo. En este marco, las relaciones entre los factores contextuales, que son necesarios para comprender las dinámicas en la formación psicológica, y los factores relacionados con el ejercicio ético de la profesión deben incluirse en el análisis. El objetivo del estudio fue, entonces, evidenciar, a través de un análisis contingencial de los planes de estudio de los programas de psicología en Colombia, las relaciones de interdependencia entre los diferentes actores que intervienen en la formación ética, el entrelazamiento de las contingencias de refuerzo individual y las consecuencias culturales. Metodología. Estudio cualitativo de análisis documental con la metodología propuesta por Todorov en cuanto al análisis contingencial. Resultados. Se muestran prácticas entrelazadas en términos de metacontingencias en las instituciones formativas, más enfocadas al desarrollo profesional que a la formación ética. A nivel interinstitucional, las prácticas no evidencian una metacontingencia en sentido estricto, lo cual se analiza a la luz de la política de autonomía universitaria y de libertad de cátedra. La mala praxis puede considerarse como una macrocontingencia, desde el punto de vista de la normalización de prácticas sin una reflexión ética. Discusión. La formación en psicología se comprende como una práctica cultural, en función de contingencias entrelazadas de forma relativamente efectiva, que forma profesionales que se ajustan a las necesidades de la sociedad, postura que es coherente con lo propuesto por otros autores. Conclusiones. Es necesaria una integración efectiva del entrenamiento en competencias disciplinares con el de competencias éticas, con el fin de lograr una práctica cultural en los términos metacontingenciales analizados.

Introdução. A questão da formação ética em psicologia tem sido uma constante na Colômbia, especialmente desde a constituição da Associação Colombiana de Faculdades de Psicologia. No entanto, os relatos de deficiências na formação ética e a revisão de pesquisas, voltadas para identificar o conhecimento ético dos alunos e o comportamento profissional em psicologia, justificam um estudo mais complexo. Nesse quadro, as relações entre os fatores contextuais, necessários para compreender a dinâmica da formação psicológica, e os fatores relacionados ao exercício ético da profissão devem ser incluídos na análise. O objetivo do estudo foi, portanto, mostrar, através de uma análise contingencial dos planos de estudo dos programas de psicologia na Colômbia, as relações de interdependência entre os diferentes atores envolvidos na formação ética, o entrelaçamento das contingências de reforço individual e consequências culturais. Metodologia. Estudo qualitativo de análise documental com a metodologia proposta por Todorov em termos de análise de contingência. Resultados. Práticas entrelaçadas se mostram em termos de meta-contingências nas instituições formadoras, mais voltadas para o desenvolvimento profissional do que para a formação ética. No plano interinstitucional, as práticas não apresentam uma meta-contingência em sentido estrito, o que é analisado à luz da política de autonomia universitária e liberdade acadêmica. A práxis errada pode ser considerada uma macro-contingência, do ponto de vista da normalização de práticas sem reflexão ética. Discussão. A formação em psicologia é entendida como uma prática cultural, baseada em contingencias relativamente efetivamente entrelaçadas, que forma profissionais que se ajustam às necessidades da sociedade, posição condizente com a proposta por outros autores. Conclusões. É necessária uma integração efetiva da formação em competências disciplinares com a de competências éticas, a fim de alcançar uma prática cultural nos termos meta-contingenciais analisados.
