Aesthetic Outcomes and Patient Satisfaction in Laparoscopic vs. Open Incisional Hernia Repair: Have We Asked the Patients?

Background: Incisional hernias are predominantly treated through open or laparoscopic surgery, with each method influencing recovery and patient-reported outcomes. This underscores the need for reliable assessment tools such as the EuraHS-QoL questionnaire to evaluate quality of life after surgery. Methods: This prospective single-center study was aimed at evaluating aestethic outcomes and patient satisfaction following laparoscopic versus open hernia repair. It involved 222 patients categorized by type of approach. The EuraHS-QoL questionnaire was used preoperatively and at 1- and 3-months post-surgery, with data analysis performed using Origin Pro 2018 and SPSS software version 28.0. Results: Among the participants, 152 were females and 70 males, with 78% undergoing open surgery and 22% laparoscopic. Findings revealed superior patient outcomes with laparoscopic repair in terms of pain management, daily activities, and aesthetic satisfaction. Patients reported significantly lower pain levels and fewer restrictions in daily activities post-laparoscopic surgery. While initial postoperative cosmetic results favored laparoscopic methods, the perceived differences in abdominal shape diminished over time. Conclusions: Laparoscopic repair significantly improves quality of life compared to open surgery, as shown by EuraHS-QoL scores. These results support the use of laparoscopic techniques in appropriate cases due to their benefits in pain reduction and faster functional recovery.

Emergency and Elective Colorectal Cancer-Relationship between Clinical Factors, Tumor Topography and Surgical Strategies: A Cohort Study.

Background and Objectives: The purpose of the study was to analyze the relationships among several clinical factors and also the tumor topography and surgical strategies used in patients with colorectal cancer. Materials and Methods: We designed an analytical, observational, retrospective study that included patients admitted to our emergency surgical department and diagnosed with colorectal cancer. The study group inclusion criteria were: patients admitted during 2020-2022; patients diagnosed with colorectal cancer (including the ileocecal valve); patients who benefited from a surgical procedure, either emergency or elective. Results: In our study group, consisting of 153 patients, we accounted for 56.9% male patients and 43.1% female patients. The most common clinical manifestations were pain (73.2% of the study group), followed by abdominal distension (69.3% of the study group) and absence of intestinal transit (38.6% of the study group). A total of 69 patients had emergency surgery (45.1%), while 84 patients (54.9%) benefited from elective surgery. The most frequent topography of the tumor was the sigmoid colon, with 19.60% of the patients, followed by the colorectal junction, with 15.68% of the patients, and superior rectum and inferior rectum, with 11.11% of the patients in each subcategory. The most frequent type of procedure was right hemicolectomy (21.6% of the study group), followed by rectosigmoid resection (20.9% of the study group). The surgical procedure was finished by performing an anastomosis in 49% of the patients, and an ostomy in 43.1% of the patients, while for 7.8% of the patients, a tumoral biopsy was performed. Conclusions: Colorectal cancer remains one of the most frequent cancers in the world, with a heavy burden that involves high mortality, alterations in the quality of life of patients and their families, and also the financial costs of the medical systems.

Molecular Deciphering of Colorectal Cancer: Exploring Molecular Classifications and Analyzing the Interplay among Molecular Biomarkers MMR/MSI, KRAS, NRAS, BRAF and CDX2 - A Comprehensive Literature Review.

Background: Colorectal cancer (CRC) exhibits molecular and morphological diversity, involving genetic, epigenetic alterations, and disruptions in signaling pathways. This necessitates a comprehensive review synthesizing recent advancements in molecular mechanisms, established biomarkers, as well as emerging ones like CDX2 for enhanced CRC assessment. Material and Methods: This review analyzes the last decade's literature and current guidelines to study CRC's molecular intricacies. It extends the analysis beyond traditional biomarkers to include emerging ones like CDX2, examining their interaction with carcinogenic mechanisms and molecular pathways, alongside reviewing current testing methodologies. Results: A multi-biomarker strategy, incorporating both traditional and emerging biomarkers like CDX2, is crucial for optimizing CRC management. This strategy elucidates the complex interaction between biomarkers and the tumor's molecular pathways, significantly influencing prognostic evaluations, therapeutic decision-making, and paving the way for personalized medicine in CRC. Conclusions: This review proposes CDX2 as an emerging prognostic biomarker and emphasizes the necessity of thorough molecular profiling for individualized treatment strategies. By enhancing CRC treatment approaches and prognostic evaluation, this effort marks a step forward in precision oncology, leveraging an enriched understanding of tumor behavior.

Large Symptomatic Inguinoscrotal Seroma Occurred Early after Laparoscopic Total Extraperitoneal Hernia Repair (TEP): a Case Report and Literature Review.

Inguinoscrotal hernia (ISH) is an entity for which treatment is under debate. Open surgery is the standard approach, but the laparoscopic technique has a great outcome when used by experienced surgeons. Seroma is one of the complications following laparoscopic hernia repair for these scrotal hernias, which is due to the large hernia sac, usually transected, leaving in place a remnant of the sac. Conservative measures can be applied for the treatment of seroma; however, in symptomatic cases, puncture and aspiration of fluid are recommended. Sometimes, these seromas can reach a large size and require surgery to remove the remnant sac. Herein, we report the case of a 49-year-old male with a large seroma that occurred four days after the laparoscopic approach - total extraperitoneal repair (TEP) for inguinoscrotal hernia. Conservative measures failed, and because the symptoms were not alleviated, reintervention was opted for. The distal sac was excised and the patient recovered uneventfully. The six-month follow-up did not show any recurrence of the hernia or seroma. We emphasize the importance of sac management in large ISH cases and discuss seromas after laparoscopic hernia repair in such instances.

Evaluation of the Immunohistochemical Scoring System of CDX2 Expression as a Prognostic Biomarker in Colon Cancer.

Encoded by the CDX2 homeobox gene, the CDX2 protein assumes the role of a pivotal transcription factor localized within the nucleus of intestinal epithelial cells, orchestrating the delicate equilibrium of intestinal physiology while intricately guiding the precise development and differentiation of epithelial tissue. Emerging research has unveiled that positive immunohistochemical expression of this protein shows that the CDX2 gene exerts a potent suppressive impact on tumor advancement in colorectal cancer, impeding the proliferation and distant dissemination of tumor cells, while the inhibition or suppression of CDX2 frequently correlates with aggressive behavior in colorectal cancer. In this study, we conducted an immunohistochemical assessment of CDX2 expression on a cohort of 43 intraoperatively obtained tumor specimens from patients diagnosed with colon cancer at Colțea Clinical Hospital in Bucharest, between April 2019 and December 2023. Additionally, we shed light on the morphological diversity within colon tumors, uncovering varying differentiation grades within the same tumor, reflecting the variations in CDX2 expression as well as the genetic complexity underlying these tumors. Based on the findings, we developed an innovative immunohistochemical scoring system that addresses the heterogeneous nature of colon tumors. Comprehensive statistical analysis of CDX2 immunohistochemical expression unveiled significant correlations with known histopathological parameters such as tumor differentiation grades (p-value = 0.011) and tumor budding score (p-value = 0.002), providing intriguing insights into the complex involvement of the CDX2 gene in orchestrating tumor progression through modulation of differentiation processes, and highlighting its role in metastatic predisposition. The compelling correlation identified between CDX2 expression and conventional histopathological parameters emphasizes the prognostic significance of the CDX2 biomarker in colon cancer. Moreover, our novel immunohistochemical scoring system reveals a distinct subset of colon tumors exhibiting reserved prognostic outcomes, distinguished by their "mosaic" CDX2 expression pattern.

Laparoscopic approach of inguinal hernia associated with adult cryptorchidism: case series and literature review.

Cryptorchidism is defined as the extra-scrotal position of the testes. It is a common disorder in male children, but rarely in adult patients. The association of cryptorchidism with hernia is a common finding in childhood, but is not frequent in adults or the elderly. Herein, we report a series of three cases (28-, 24-, and 34-year-old men) of adult inguinal hernia combined with cryptorchidism successfully managed by laparoscopic surgery under the same operative view. Laparoscopic transabdominal preperitoneal repair and orchiectomy were performed in all patients. No complications occurred in the postoperative period, and the patients were discharged on the first or second postoperative day. Pathological examination of the specimens revealed atrophic testes without malignancy. No hernia recurrence was observed during follow-up. The laparoscopic approach in the combined pathology of inguinal hernia and cryptorchidism is feasible in adult patients and has multiple advantages in terms of diagnosis and management.

Autoimmune encephalitis in a resource-limited public health setting: a case series analysis / Encefalite autoimune em um hospital universitário público: análise de uma série de casos

Abstract Background Autoimmune encephalitis (AE) consists of a group of acquired diseases that affect the central nervous system. A myriad of phenotypes may be present at the onset. Due to the heterogeneity of clinical presentations, it is difficult to achieve uniformity for the diagnostic and therapeutic processes and follow-up strategies. Objective To describe a series of patients diagnosed with AE in a resource-limited public hospital in southern Brazil and to analyze therapeutics and outcomes. Methods We retrospectively reviewed the electronic medical records of patients diagnosed with AE at the Hospital de Clínicas de Porto Alegre from 2014 to 2022. Data collected included clinical presentation, neuroimaging, cerebrospinal fluid testings, electroencephalogram, autoantibodies, treatments, outcomes, follow-up time, degree of neurological impairment, and mortality. Results Data from 17 patients were retrieved. Eleven cases were classified as definite AE and 6 as possible AE. Autoantibodies were identified in 9 patients. Timing for diagnosis was impacted by the high costs associated with autoantibody testing. Most patients became functionally dependent (82.4%) and most survivors remained with autoimmune-associated epilepsy (75%). Five patients died during hospitalization, and one after a 26-month of follow-up. Conclusion In this resource-limited hospital, patients with AE had a worse clinical outcome than that previously described in the literature. Development of epilepsy during follow-up and mortality were greater, whilst functional outcome was inferior. Autoantibody testing was initially denied in most patients, which impacted the definitive diagnosis and the use of second-line therapies.

Resumo Antecedentes A encefalite autoimune (EA) consiste em um grupo de doenças adquiridas que afetam o sistema nervoso central. Objetivo Descrever uma série de pacientes diagnosticados com EA em um contexto de atenção terciária à saúde com recursos limitados e analisar a terapêutica e os resultados. Métodos Revisamos retrospectivamente os prontuários eletrônicos de pacientes diagnosticados com EA no Hospital de Clínicas de Porto Alegre de 2014 a 2022. Os dados coletados incluíram apresentação clínica, neuroimagem, exames de líquido cefalorraquidiano, eletroencefalograma, autoanticorpos, tratamentos, resultados, tempo de acompanhamento, grau de comprometimento neurológico e mortalidade. Resultados Dados de 17 pacientes foram coletados. Onze casos foram classificados como EA definitivo e seis como EA possível. Autoanticorpos foram identificados em nove pacientes. O tempo para o diagnóstico foi afetado pelos altos custos associados ao teste de autoanticorpos. A maioria dos pacientes tornou-se funcionalmente dependente (82,4%), e a maioria dos sobreviventes permaneceu com epilepsia autoimune associada (75%). Cinco pacientes faleceram durante a internação, e um após 26 meses de seguimento. Conclusão No hospital em questão, os pacientes com EA tiveram um desfecho clínico pior do que o previamente descrito na literatura. O desenvolvimento de epilepsia durante o acompanhamento e a mortalidade foram maiores, enquanto o desfecho funcional foi inferior. Os testes de autoanticorpos foram inicialmente negados para a maioria dos pacientes, o que impactou o diagnóstico definitivo e o uso de terapias de segunda linha.

Validation of a New Prognostic Score in Patients with Ovarian Adenocarcinoma.

Background and Objectives: This study aimed to assess the impact of clinical prognostic factors and propose a prognostic score that aids the clinician's decision in estimating the risk for patients in clinical practice. Materials and Methods: The study included 195 patients diagnosed with ovarian adenocarcinoma. The therapeutic strategy involved multidisciplinary decisions: surgery followed by adjuvant chemotherapy (80%), neoadjuvant chemotherapy followed by surgery (16.4%), and only chemotherapy in selected cases (3.6%). Results: After a median follow-up of 68 months, in terms of progression-free survival (PFS) and overall survival (OS), Eastern Cooperative Oncology Group (ECOG) performance status of 1 and 2 vs. 0 (hazard ratio-HR = 2.71, 95% confidence interval-CI, 1.96-3.73, p < 0.001 for PFS and HR = 3.19, 95%CI, 2.20-4.64, p < 0.001 for OS), menopausal vs. premenopausal status (HR = 2.02, 95%CI, 1.35-3,0 p < 0.001 and HR = 2.25, 95%CI = 1.41-3.59, p < 0.001), ascites (HR = 1.95, 95%CI 1.35-2.80, p = 0.03, HR = 2.31, 95%CI = 1.52-3.5, p < 0.007), residual disease (HR = 5.12, 95%CI 3.43-7.65, p < 0.0001 and HR = 4.07, 95%CI = 2.59-6.39, p < 0.0001), and thrombocytosis (HR = 2.48 95%CI = 1.72-3.58, p < 0.0001, HR = 3.33, 95%CI = 2.16-5.13, p < 0.0001) were associated with a poor prognosis. An original prognostic score including these characteristics was validated using receiver operating characteristic (ROC) curves (area under the curve-AUC = 0.799 for PFS and AUC = 0.726 for OS, p < 0.001). The median PFS for patients with none, one, two, three, or four (or more) prognostic factors was not reached, 70, 36, 20, and 12 months, respectively. The corresponding median overall survival (OS) was not reached, 108, 77, 60, and 34 months, respectively. Conclusions: Several negative prognostic factors were identified: ECOG performance status ≥ 1, the presence of ascites and residual disease after surgery, thrombocytosis, and menopausal status. These led to the development of an original prognostic score that can be helpful in clinical practice.

Primary central nervous system lymphoma in a patient with multiple sclerosis using fingolimod.

Primary central nervous system lymphoma (PCNSL) is an uncommon lymphoproliferative disease associated with immunosuppression. Here, we report the case of a patient with multiple sclerosis, under treatment with fingolimod (FTY720, Gilenya) for 4 years, who developed this condition. Although the causal relationship cannot be established, there are cases in the literature that describe the appearance of lymphoma after the use of this medication. Considering the high mortality of PCNSL, epidemiological studies are necessary to establish a relationship between its arising and the use of immunosuppressants.

Appendiceal Endometriosis with Intestinal Metaplasia Mimicking Appendiceal Mucinous Neoplasm - A Case Report and a Concise Review for the Practicing Pathologist.

Appendiceal endometriosis is a rare entity and, when accompanied by intestinal metaplasia, represents a challenging differential diagnosis with low-grade appendiceal mucinous neoplasm (LAMN). We present the case of a 47 years-old woman, with multiple surgical interventions for endometriosis, with persistent symptoms despite chronic hormonal treatment, with imaging showing stage IV endometriosis. Hence, en bloc low rectum resection with total hysterectomy and bilateral adnexectomy was performed, followed by appendectomy. Unexpectedly, despite the gross normal macroscopic appearance of the appendix, microscopy showed multiple endometriosis foci, consisting of endometrial glands embedded in varying amounts of endometrial stroma. As some of these glands were bordered by mucinous-type epithelium containing intestinal cells, Goblet cells, Paneth cells in addition to the presence of mucus-filled microcysts, immunohistochemistry (IHC) was performed in order to differentiate between intestinal-metaplasia and LAMN. IHC showed positivity of the endometrial epithelium for KRT7, estrogen receptor (ER) and progesterone receptor (PR). Both the appendiceal mucosa and the intestinal-type metaplastic epithelium of the glandular structures were positive for KRT20. Additionally, the endometrial stroma enclosing endometrial glands, as well as the stroma surrounding mucinous-type metaplastic epithelium, were positive for CD10, ER and PR. This patient's case draws attention to the rare occurrence of appendiceal endometriosis and the uncommon intestinal metaplasia, which can easily mimic LAMN, emphasizing the paramount importance of the differential diagnosis with this type of neoplasia.

Solitary fibrous tumor developing in the right retroperitoneal space.

Solitary fibrous tumor (SFT) is a rare mesenchymal tumor that is quite aggressive and prone to recurrence and metastasis. Most SFTs are benign, but the identification of the histological features that define the dedifferentiation of SFTs can predict the aggressiveness of the tumor and the presence of a reserved prognosis. We present a rare case of conventional SFTs with features of malignancy and highlight the diagnostic and therapeutic difficulties related to this case. Computed tomography aspect suggested a possible gastrointestinal stromal tumor. Surgical intervention was performed through median laparotomy and a tumor of approximately 15∕12 cm was found, developed from the level of the right retroperitoneal space, and pushing anteriorly the ascending colon, cecum, and terminal ileum. The immunohistochemical aspect correlated with the histopathological one suggests a SFT most likely malignant. In conclusion, the early diagnosis of SFTs is essential in establishing an appropriate treatment. Immunohistochemistry is indispensable in establishing the diagnosis of SFTs.

Surgical Approach to Bilateral Inguinal Hernia. A Case-Control Study.

Introduction: Bilateral inguinal hernia can be safely repaired simultaneously, open or minimally invasive, in an elective sce-nario. The choice of surgical approach depends on the patient's status, hernia characteristics, surgeons and patient preferences. Whether age criteria should be considered when selecting between the two approaches is still a matter of debate. Considering that there is no consensus regarding the best repair in bilateral inguinal herniorrhaphy, the aim of the study is to perform an analysis regarding elective surgical approach of patients with bilateral inguinal hernias. Material and Methods: To study the relationship between exposure to an open versus laparoscopic approach in patients with bilateral inguinal hernia, we conducted a case-control study. In our retrospective analysis, cases (23 patients) were the open-approach hernia repair, and controls (82 patients) were laparoscopic hernia repair. We analyzed two sets of variables: first, related to patient characteristics (age 65 years, BMI 30 kg/m2, smoking habit, HTA status, COPD status, DM status, use of anticoagulants, presence of neoplastic status) and second, variables related to hernia features (inguinoscrotal hernia, recurrent hernia and complicated hernia). Results: The mean age for cases was 73.26 (Ã+-12.99) years and that of controls, was 56.48 (Ã+-15.15) years. Univariate analysis demonstrated four variables with statistical significance: age 65 years, inguinoscrotal hernia, neo-plastic status, and anticoagulant use. When introduced into the multivariate analysis, we noted that only two variables, age 65 years (OR=4.183, 95% CI [1.289, 13.572], p=0.017) and use of anticoagulants (OR=38.876, 95% CI [1.305, 1158.011], p=0.035) reached statistical significance. Conclusion: This study demonstrates that when we refer to bilateral inguinal hernia repair, patients aged 65 years are at risk of having an open procedure at least fourfold more than patients aged 65 years. In addition, the use of anticoagulants increases the risk of open hernia repair 38 times more than that of minimally invasive repair for the same age group. Interestingly, in our study, hernia characteristics were not found to be associated with open hernia repair and age 65 years. In our study we found that age 65 years is associated with electing open hernia repair over minimally invasive repair, which can be linked to age-related risk factors. Further re-search is needed to investigate the impact of age and age-related risk factors on surgical outcomes of bilateral inguinal hernia repair.

The Effect of Neoadjuvant Radiotherapy on the Pathological Response in Patients with Rectal Cancer.

OBJECTIVE: The aim of this retrospective study was to describe the long-term outcomes and the survival rate in patients who underwent neoadjuvant therapy for rectal cancer. This is a retrospective study undertaken in a surgery department of an oncological clinical hospital. The study evaluated the data of all patients treated for rectal cancer between January 2014 and December 2018. Results: Of 126 patients, thirteen patients with mean age of 58.3 years had a pathological complete response and were treated with neoadjuvant chemoradiotherapy. Ten patients (76.9%) underwent treatment with 45 Gy. One patient was treated with 51 Gy, one with 49.3 Gy, and 12 patients were treated daily with 1.8 Gy. One patient underwent a short course of 5 days with 5 Gy. Patients diagnosed and treated in 2016 had a survival rate of 54 to 57 months, in 2017 42 to 48 months and in 2018 29 to 34 months. For two patients with final pCR, the adjuvant treatment was given and the wait and watch policy was applied. Both patients were females, aged 51 and 66 years (mean age 58.5 years). CONCLUSION: The frequency of pCR was similar to that in other published studies. The survival rate in our cohort was high, death occurring in two cases, one being the oldest patient in the study. We concluded that the long-term oncological control is excellent in patients who receive neoadjuvant treatment leading to improved OS, improved quality of life, and decreasing the recurrence rates.

Findings suggestive of coronary microvascular dysfunction in cats with myocardial ischemia.

Background: Myocardial infarction (MI) is an important cause of death and disability among humans worldwide. Few studies have reported the occurrence of MI in small animals as well. Reports in human medicine indicate that up to 30% of patients with clinical signs compatible with myocardial ischemia suggestive of coronary disease exhibit normal epicardial arteries at angiography. These symptoms have been associated with a syndrome characterized by alterations in cardiac microvasculature, known as coronary microvascular dysfunction (CMD). Aim: This study aimed to describe the necropsy findings and clinical-pathological characterization (when available) of cats with histopathological findings suggesting CMD. Methods: Necropsy records of cats presenting histopathological diagnosis compatible with acute and/or chronic MI, with normal epicardial arteries and microvascular disorders were evaluated. Results: Twenty animals met the inclusion criteria. Eight cats (40%) exhibited findings compatible with mild hypertrophic cardiomyopathy (HCM) without left atrial enlargement, one (5%) presented restrictive cardiomyopathy, and another one (5%) had lesions consistent with histiocytoid cardiomyopathy. The remaining cats (50%) showed alterations compatible with severe HCM with left atrial enlargement. In all cases, epicardial arteries were normal (without obstruction). All the evaluated hearts exhibited myocardial multifocal fibrosis along with replacement of cardiomyocytes by adipose tissue and blood vessels with hyperplasia and hypertrophy of the muscular layer with protrusion of the nuclei of the endothelial cells. Conclusion: These findings suggest the presence of microvascular dysplasia of the coronary arteries. Further studies are necessary to confirm and clinically characterize these results.

Surgical Features after Neoadjuvant Treatment for Breast Cancer.

Introduction: Patients with breast cancer may receive neoadjuvant cancer treatment in order to benefit from radical surgery or to turn an indication for extensive surgery into a conservatory or oncoplastic operation. AIM: To establish the main implications of therapeutic management of the cases of breast cancer treated initially with chemotherapy followed by surgery. MATERIAL AND METHOD: 35 breast cancer patients operated in 2020 after NACT (neoadjuvant chemotherapy) in Surgery Clinic of Coltea Hospital are analyzed, and the response after treatment is pathologicaly evaluated using the Residual Cancer Burden method Results: The results of the analysis of the group of patients showed that most patients presented downstaging of the disease after neoadjuvant treatment with a proportion of 17,14% with complete pathologic response. DISCUSSIONS: We performed clinical and imagistic evaluation of patients before and after NACT and pathologic evaluation of the surgical specimen using residual tumor burden method, taking into account the age of the patients, clinical and pathological staging and the status of hormone receptors and Her 2. Conclusions: Neoadjuvant chemotherapy is currently part of the therapeutic arsenal of breast cancer being followed in most cases by downstaging of tumors and increasing the number of cases that can be operated. 17.1% of cases achieved pathologic complete response, 2 of them being Her 2 positive carcinomas. The use of conservative and oncoplastic surgical techniques is possible after downstaging tumors by NACT.

Recomendaciones de política pública como estrategia reflexiva en los estudios de políticas alimentarias y nutricionales en Colombia 2000-2015 / Public Policy Recommendations as a Reflexive Strategy in Studies of Food and Nutrition Policies in Colombia 2000-2015

Resumen Antecedentes: existe una deuda histórica con el análisis de las políticas públicas alimentarias y nutricionales que permita su reubicación en una nueva lógica que aporte a la consolidación de un sistema de garantía progresiva del derecho humano a la alimentación. Objetivo: abordar las recomendaciones de política pública de estudios de políticas alimentarias y nutricionales colombianas ubicadas en el periodo 2000-2015. Materiales y métodos: diseño metodológico de corte cualitativo basado en el análisis de 36 documentos que contienen aportes analíticos para la formulación, implementación y evaluación de políticas públicas del campo alimentario y nutricional. Resultados: se ubicaron tres tipos de recomendaciones técnicas: 1) las que proponen el abordaje e intervención de cuestiones estructurales que trascienden a los tomadores de decisiones y se relacionan con atributos macro de los problemas públicos; 2) las concentradas en la redefinición de los problemas públicos; y 3) las que enfatizan en la recomposición de procesos, instituciones y diseño de instrumentos de política pública. Conclusiones: abogar por los problemas públicos desde los determinantes sociales de la salud, alimentación y nutrición, y modificar el referencial de las políticas públicas al promover nuevas escuelas de pensamiento, académico, político y social; giros conceptuales y metodológicos que son necesarios para reubicar estas políticas públicas.

Abstract Background: There is a historical lack of analyses of dietary and nutritional public policies that now allows for a repositioning and new logic to contribute to the consolidation of a progressive system that guarantees the right to food. Objective: Address public policy recommendations in studies of Colombian food and nutrition policies during the years 2000-2015. Materials and Methods: Qualitative methodological design based on the analysis of 36 documents containing analytical contributions to the formulation, implementation, and evaluation of public policies in the food and nutrition field. Results: Three types of technical recommendations were discovered: 1) those that propose the approach and intervention of structural issues that transcend decision makers and are related to macro attributes of public problems; 2) those focused on the redefinition of public problems; and 3) those that emphasize the recomposition of institutional processes and the design of public policy instruments. Conclusions: Advocate for public problems from the purvue of social determinants of health, food, and nutrition, and modify public policies by promoting new schools of thought-academic, political and social. These conceptual and methodological paradigm shifts are necessary to reposition these public policies.
