Public and Research Interest in Telemedicine From 2017 to 2022: Infodemiology Study of Google Trends Data and Bibliometric Analysis of Scientific Literature.

BACKGROUND: Telemedicine offers a multitude of potential advantages, such as enhanced health care accessibility, cost reduction, and improved patient outcomes. The significance of telemedicine has been underscored by the COVID-19 pandemic, as it plays a crucial role in maintaining uninterrupted care while minimizing the risk of viral exposure. However, the adoption and implementation of telemedicine have been relatively sluggish in certain areas. Assessing the level of interest in telemedicine can provide valuable insights into areas that require enhancement. OBJECTIVE: The aim of this study is to provide a comprehensive analysis of the level of public and research interest in telemedicine from 2017 to 2022 and also consider any potential impact of the COVID-19 pandemic. METHODS: Google Trends data were retrieved using the search topics "telemedicine" or "e-health" to assess public interest, geographic distribution, and trends through a joinpoint regression analysis. Bibliographic data from Scopus were used to chart publications referencing the terms "telemedicine" or "eHealth" (in the title, abstract, and keywords) in terms of scientific production, key countries, and prominent keywords, as well as collaboration and co-occurrence networks. RESULTS: Worldwide, telemedicine generated higher mean public interest (relative search volume=26.3%) compared to eHealth (relative search volume=17.6%). Interest in telemedicine remained stable until January 2020, experienced a sudden surge (monthly percent change=95.7%) peaking in April 2020, followed by a decline (monthly percent change=-22.7%) until August 2020, and then returned to stability. A similar trend was noted in the public interest regarding eHealth. Chile, Australia, Canada, and the United States had the greatest public interest in telemedicine. In these countries, moderate to strong correlations were evident between Google Trends and COVID-19 data (ie, new cases, new deaths, and hospitalized patients). Examining 19,539 original medical articles in the Scopus database unveiled a substantial rise in telemedicine-related publications, showing a total increase of 201.5% from 2017 to 2022 and an average annual growth rate of 24.7%. The most significant surge occurred between 2019 and 2020. Notably, the majority of the publications originated from a single country, with 20.8% involving international coauthorships. As the most productive country, the United States led a cluster that included Canada and Australia as well. European, Asian, and Latin American countries made up the remaining 3 clusters. The co-occurrence network categorized prevalent keywords into 2 clusters, the first cluster primarily focused on applying eHealth, mobile health (mHealth), or digital health to noncommunicable or chronic diseases; the second cluster was centered around the application of telemedicine and telehealth within the context of the COVID-19 pandemic. CONCLUSIONS: Our analysis of search and bibliographic data over time and across regions allows us to gauge the interest in this topic, offer evidence regarding potential applications, and pinpoint areas for additional research and awareness-raising initiatives.

Blood-Transfusion Risk Factors after Intramedullary Nailing for Extracapsular Femoral Neck Fracture in Elderly Patients.

BACKGROUND: Extracapsular femoral neck fractures (eFNF) are the third most common type of fracture in traumatology. Intramedullary nailing (IMN) is one of the most frequently used ortho-pedic treatments for eFNF. Blood loss is one of the main complications of this treatment. This study aimed to identify and evaluate the perioperative risk factors that lead to blood transfusion in frail patients with eFNF who undergo IMN. METHODS: From July 2020 to December 2020, 170 eFNF-affected patients who were treated with IMN were enrolled and divided into two groups according to blood transfusion: NBT (71 patients who did not need a blood transfusion), and BT (72 patients who needed blood transfusion). Gender, age, BMI, pre-operative hemoglobin levels, in-ternational normalized ratio (INR) level, number of blood units transfused, length of hospital stay, surgery duration, type of anesthesia, pre-operative ASA score, Charlson Comorbidity Index, and mortality rate were assessed. RESULTS: Cohorts differed only for pre-operatively Hb and surgery time (p < 0.05). CONCLUSION: Patients who have a lower preoperative Hb level and longer surgery time have a high blood-transfusion risk and should be closely followed peri-operatively.

Comparison of Quantitative Real-Time PCR and Digital PCR to Detect the Polyomavirus in Merkel Cell Carcinoma.

Merkel cell polyomavirus (MCPyV) prevalence in Merkel cell carcinoma (MCC) cases is controversial. The detection and quantification of MCPyV DNA is mainly performed by PCR techniques using formalin-fixed, paraffin-embedded (FFPE) tissues. The aim of this study is to compare the performance of two different molecular techniques, specifically the quantitative Real-Time PCR (qPCR) and digital PCR (dPCR). Samples from 31 cases of MCC excisional surgical biopsies were analyzed. DNA extraction and purification from clinical samples were performed using the QIAcube Qiagen automated nucleic acid extractor. After the extraction, MCPyV was detected by qPCR and dPCR using specially designed primers and probes. Of the 31 MCC samples under study, the MCPyV genome was detected in 11 samples (35%) by qPCR compared with 20 samples (65%) detected by dPCR. Notably, 65% of primary tumors were positive for MCPyV (15/23). The viral genome was detected in 75% of tumors located at UV-exposed sites (6/8), 55% of tumors at partially UV-protected sites (5/9), and 67% of tumors at UV-protected sites (4/6). Our results showed a better sensitivity of dPCR in detecting the MCPyV genome in MCC samples compared with traditional qPCR techniques.

Comparison of RIPASA and ALVARADO scores for risk assessment of acute appendicitis: A systematic review and meta-analysis.

BACKGROUND: In the last decades, several clinical scores have been developed and currently used to improve the diagnosis and risk management of patients with suspected acute appendicitis (AA). However, some of them exhibited different values of sensitivity and specificity. We conducted a systematic review and metanalysis of epidemiological studies, which compared RIPASA and Alvarado scores for the diagnosis of AA. METHODS: This systematic review was conducted using PubMed and Web of Science databases. Selected studies had to compare RIPASA and Alvarado scores on patients with suspected AA and reported diagnostic parameters. Summary estimates of sensitivity and specificity were calculated by the Hierarchical Summary Receiver Operating Curve (HSROC) using STATA 17 (STATA Corp, College Station, TX) and MetaDiSc (version 1.4) software. RESULTS: We included a total of 33 articles, reporting data from 35 studies. For the Alvarado score, the Hierarchical Summary Receiver Operating Curve (HSROC) model produced a summary sensitivity of 0.72 (95%CI = 0.66-0.77), and a summary specificity of 0.77 (95%CI = 0.70-0.82). For the RIPASA score, the HSROC model produced a summary sensitivity of 0.95 (95%CI = 0.92-0.97), and a summary specificity of 0.71 (95%CI = 0.60-0.80). CONCLUSION: RIPASA score has higher sensitivity, but low specificity compared to Alvarado score. Since these scoring systems showed different sensitivity and specificity parameters, it is still necessary to develop novel scores for the risk assessment of patients with suspected AA.

Left Paraduodenal Hernia in a Young Patient with Recurrent Abdominal Pain: A Case Report and Short Literature Review.

BACKGROUND Internal hernias are a rare cause of small bowel obstruction in patients, which usually have a long history of mild abdominal symptoms, sometimes leading to emergency surgery due to acute abdominal pain. Occasionally, it takes a long time to make the correct diagnosis because of symptoms vagueness and transience of typical imaging findings; at times, a definitive diagnosis is possible only through surgery, especially in cases of acute presentations in a low-resource setting where high-performance diagnostic equipment may be unavailable. CASE REPORT We report the case of a young male patient with a long history of mild abdominal symptoms and some episodes of acute abdominal pain. Following one of these episodes, several diagnostic examinations were performed and he was diagnosed with left paraduodenal hernia after typical signs were found on imaging exams, both CT and MRI; the patient underwent laparotomy with reduction of intestinal loops in the peritoneal cavity and suturing of the sac and was eventually discharged with no further symptoms whatsoever. CONCLUSIONS Among internal hernias, left paraduodenal hernias account for the major part and are characterized by the protrusion of bowel loops through the fossa of Landzert; herniated loops produce a sac-like appearance (typical imaging sign on both CT and MRI) and may cause partial displacement of other organs and blood vessels. Internal hernias should always be considered as a rare differential diagnosis in the workup of a patient with abdominal pain or intestinal obstruction: knowledge of both typical imaging features and specific surgical techniques are mandatory so that these patients may be properly cared for.

Subtotal cholecystectomy for Mirizzi syndrome: Should we ever remove the stone? A case report.

INTRODUCTION AND IMPORTANCE: Mirizzi Syndrome is a rare complication of cholelithiasis.In this case report the Authors present an original surgical approach for the treatment of complicated gallbladders, based on open subtotal cholecystectomy, leaving in situ the stone. This is the first case showing safety and reliability of the present strategy at a four-year follow-up. CASE PRESENTATION: A 68-year-old patient came to our emergency room with abdominal pain, leukocytosis and fever. At surgical exploration he presented a sclerotic retraction of the gallbladder together with an intrahepatic abscess, that forced us first to perform an open subtotal cholecystectomy, resecting the gallbladder cranially and leaving in situ the stone. CLINICAL DISCUSSION: The post-operative course was uneventful. The four-year clinical, US and CT scan follow-up was negative and the patient referred a normal quality of life. The present strategy could be considered an intraoperative rescue option in such a complex operative scenario in which is impossible to safely remove the stone. CONCLUSION: This case report demonstrates how in selected cases, when absolutely necessary and unavoidable without high risks, the stone can be left in situ as an eventual stone resection would be extremely risky.

How COVID-19 Has Influenced Public Interest in Antimicrobials, Antimicrobial Resistance and Related Preventive Measures: A Google Trends Analysis of Italian Data.

Google Trends analytics is an innovative way to evaluate public interest in antimicrobial resistance (AMR) and related preventive measures. In the present study, we analyzed Google Trends data in Italy, from 2016 to 2021. A joinpoint analysis was performed to assess whether and how annual campaigns and the COVID-19 pandemic affected public interest in antimicrobials, AMR, hand hygiene, and the use of disinfectant. For the terms "antimicrobials" and "antimicrobial resistance", no joinpoints were detected around the time of the World Antimicrobial Awareness Week. Similarly, the COVID-19 pandemic seems to have had no effect on public interest in this term. For the term "handwashing", no joinpoints were detected around World Hand Hygiene Day or Global Handwashing Day. However, three joinpoints were detected around the peak of interest observed in March 2020, after the beginning of the COVID-19 pandemic. Comparable results were obtained for the term "disinfectant". These findings show that the influence of annual campaigns on public interest in AMR and preventive measures was modest and not long-term. The COVID-19 pandemic, meanwhile, had no effect on AMR but raised awareness on preventive measures. However, this was a temporary rather than long-term outcome. Thus, different policies, strategies, and measures should be designed to advocate prevention of AMR in the COVID-19 era.

Preoperative Risk Factors for Conversion from Laparoscopic to Open Cholecystectomy: A Systematic Review and Meta-Analysis.

Laparoscopic cholecystectomy is a standard treatment for patients with gallstones in the gallbladder. However, multiple risk factors affect the probability of conversion from laparoscopic cholecystectomy to open surgery. A greater understanding of the preoperative factors related to conversion is crucial to improve patient safety. In the present systematic review, we summarized the current knowledge about the main factors associated with conversion. Next, we carried out several meta-analyses to evaluate the impact of independent clinical risk factors on conversion rate. Male gender (OR = 1.907; 95%CI = 1.254−2.901), age > 60 years (OR = 4.324; 95%CI = 3.396−5.506), acute cholecystitis (OR = 5.475; 95%CI = 2.959−10.130), diabetes (OR = 2.576; 95%CI = 1.687−3.934), hypertension (OR = 1.931; 95%CI = 1.018−3.662), heart diseases (OR = 2.947; 95%CI = 1.047−8.296), obesity (OR = 2.228; 95%CI = 1.162−4.271), and previous upper abdominal surgery (OR = 3.301; 95%CI = 1.965−5.543) increased the probability of conversion. Our analysis of clinical factors suggested the presence of different preoperative conditions, which are non-modifiable but could be useful for planning the surgical scenario and improving the post-operatory phase.

Nodular Sclerosing Mesenteritis: An Occasional Finding Mimicking a Spindle Cell Tumor.

BACKGROUND The term "sclerosing mesenteritis" includes a spectrum of rare idiopathic diseases involving the small and/or large bowel. It appears as a diffuse, localized, or multinodular thickening of the mesentery, with a variable degree of chronic non-specific inflammation, fat necrosis, and fibrosis. CASE REPORT Here, we report a case of 83-year-old woman with symptoms of intestinal occlusion, vomiting, and abdominal pain. Radiographic examinations showed air fluid levels in right and left quadrants and in the mesogastric site, while computed tomography (CT) documented a strangulated inguinal hernia with ileal obstruction. Based on clinical examination and radiologic findings, the patient underwent surgery for inguinal hernia reduction. The examination of viscera revealed 2 tracts of ileum with ischemic signs and covered by fibrin; thus, the 2 intestinal loops were resected. Histological examination revealed chronic non-specific inflammation of the whole intestinal wall, including the subserosa in the resected tract of proximal ileum, while the distal ileal loop (not herniated tract) showed a subserosal fibrous nodule of 2 cm in greatest diameter, composed of a proliferation of spindle cells haphazardly arranged in a collagenized stroma. The diagnosis of sclerosing mesenteritis was rendered. CONCLUSIONS The present case shows the possibility of an incidental diagnosis during another intervention such as hernia surgery. Pathologists should be aware of this disease to avoid confusion with aggressive tumors such as intra-abdominal desmoid-type fibromatosis and gastrointestinal stromal tumor.

Superior mesenteric artery syndrome (Wilkie Syndrome) with unusual clinical onset: Description of a rare case.

Wilkie's Syndrome is a very rare disease caused by reduction of aorto-mesenteric space with consequent duodenum compression. It can combine with left renal vein stenosis which, when symptomatic, is known as "Nutcracker Syndrome". We describe a clinical onset case with epigastric pain without vomiting in a normal weight patient. 28-year-old woman who came to our observation for intense epigastric pain after a weight loss of 14 kg in 4 months. Multidetector Computed Tomography and Ultrasound revealed gastric and duodenal overdistension with hydro-air levels, severe duodenum stenosis, and left renal vein compression. Wilkie's Syndrome is common in anorexic individuals suffering from recurrent postprandial vomiting, onset with severe epigastric pain, without vomiting, is quite unusual. High-calorie diet must be first therapeutic approach, in case of failure treatment of first choice should be endovascular stenting and, only in selected cases, surgical treatment should be used because it is very invasive and burdened with numerous complications. Failure to diagnose this disease can expose patients to serious health risks.

Comparison of aspiration with sclerotherapy and laparoscopic deroofing for the treatment of symptomatic simple renal cysts: a systematic review and meta-analysis.

There are currently several strategies for the treatment of symptomatic simple renal cysts, such as aspiration with sclerosants and laparoscopic deroofing. However, no clear indication exists for choosing between them. Here, we carried out a systematic review and a meta-analysis of studies, which compared symptomatic and radiological success between aspiration with sclerotherapy and laparoscopic deroofing. Results were reported as relative risk (RR) and 95% confidence interval (95% CI) using laparoscopic deroofing as control group. The symptomatic and radiological successes were evaluated by 6 and 3 studies, respectively. Notably, aspiration with sclerotherapy was associated with higher risk of failure than laparoscopic deroofing (RR = 2.82; 95% CI = 1.84-4.31 for symptomatic failure; RR = 8.31; 95% CI = 4.22-16.38 for radiological failure). On the other hand, however, aspiration with sclerotherapy was associated with less frequent complications, shorter treatment duration and post-treatment hospital stay, and lower costs. Thus, our work underlines benefits and drawbacks of each intervention, raising the need for further studies to design guidelines for the management of simple renal cysts.

Open mini-incision vs laparoscopic appendectomy A retrospective single Centre study.

INTRODUCTION: Laparoscopy appendectomy (LA) is the most widely used method for the treatment of acute appendicitis (AA). The interest has shifted towards the mini-incision open method (MOA). MATERIALS AND METHODS: A retrospective study was conducted considering all patients who underwent surgery due to suspected appendicitis from December 2014 to January 2019. The final analysis included 234 patients. The following data were collected: patient age, sex, surgery duration, hospitalization time, wound infections, and mortality. RESULTS: The average time of surgery was 69.89 minutes in the LA group and 62.17 minutes in the MOA group, while the average time of postoperative hospitalization was respectively 5.579 days and 5.143 days. Wound infections occurred in 2 patients in the LA group and in 3 patients in the MOA group. CONCLUSION: Laparoscopic appendectomy has a similar operating time, hospitalization time and wound infections as Mini-incision open appendectomy. Therefore,both techniques are to be considered valid. KEY WORDS: Appendicitis, Laparoscopic appendectomy, Appendectomy, Instrumentation, Open approach.

Applying a hierarchical clustering on principal components approach to identify different patterns of the SARS-CoV-2 epidemic across Italian regions.

Italy has experienced the epidemic of Severe Acute Respiratory Syndrome Coronavirus 2, which spread at different times and with different intensities throughout its territory. We aimed to identify clusters with similar epidemic patterns across Italian regions. To do that, we defined a set of regional indicators reflecting different domains and employed a hierarchical clustering on principal component approach to obtain an optimal cluster solution. As of 24 April 2020, Lombardy was the worst hit Italian region and entirely separated from all the others. Sensitivity analysis-by excluding data from Lombardy-partitioned the remaining regions into four clusters. Although cluster 1 (i.e. Veneto) and 2 (i.e. Piedmont and Emilia-Romagna) included the most hit regions beyond Lombardy, this partition reflected differences in the efficacy of restrictions and testing strategies. Cluster 3 was heterogeneous and comprised regions where the epidemic started later and/or where it spread with the lowest intensity. Regions within cluster 4 were those where the epidemic started slightly after Veneto, Emilia-Romagna and Piedmont, favoring timely adoption of control measures. Our findings provide policymakers with a snapshot of the epidemic in Italy, which might help guiding the adoption of countermeasures in accordance with the situation at regional level.

Epigenetic Aging and Colorectal Cancer: State of the Art and Perspectives for Future Research.

Although translational research has identified a large number of potential biomarkers involved in colorectal cancer (CRC) carcinogenesis, a better understanding of the molecular pathways associated with biological aging in colorectal cells and tissues is needed. Here, we aim to summarize the state of the art about the role of age acceleration, defined as the difference between epigenetic age and chronological age, in the development and progression of CRC. Some studies have shown that accelerated biological aging is positively associated with the risk of cancer and death in general. In line with these findings, other studies have shown how the assessment of epigenetic age in people at risk for CRC could be helpful for monitoring the molecular response to preventive interventions. Moreover, it would be interesting to investigate whether aberrant epigenetic aging could help identify CRC patients with a high risk of recurrence and a worst prognosis, as well as those who respond poorly to treatment. Yet, the application of this novel concept is still in its infancy, and further research should be encouraged in anticipation of future applications in clinical practice.

Clinical pictures mimicking acute hernia complications: are we really daring to violate a traditional abdominal wall surgery dogma?

BACKGROUND: Acute abdominal wall hernia complications usually require a prompt surgical treatment. The aim of this case series is to report our experience with some unusual cases of apparent acute and subacute hernia complications not requiring surgical treatment, changing the classical paradigm of immediate surgical approach into a "wait and see" situation. CASE PRESENTATION: We shortly report here four cases of abdominal wall hernia complications in which surgical treatment could have been unsafe for the patients considering their clinical condition. Two cases were fistulated and two were apparently strangulated. After clinical evaluation and CT-scan, we opted for a conservative treatment weighting the risk-benefit balance in order to give the best quality of life to the patient. CONCLUSIONS: In selected cases and under well-defined situations, an accurate evaluation should convince every surgeon to opt for a conservative approach refraining from a promptly operative treatment of the patient. This may be particularly relevant among very old or high-risk patients affected by long-standing abdominal wall hernias.

Adherence to the Mediterranean diet partially mediates socioeconomic differences in leukocyte LINE-1 methylation: evidence from a cross-sectional study in Italian women.

Although previous research demonstrated that socioeconomic status (SES) might affect DNA methylation, social inequalities alone do not completely explain this relationship. We conducted a cross-sectional study on 349 women (Catania, Italy) to investigate whether behaviors might mediate the association between SES and long interspersed nuclear elements (LINE-1) methylation, a surrogate marker of global DNA methylation. Educational level, used as an indicator of SES, and data on behaviors (i.e. diet, smoking habits, physical activity, and weight status) were collected using structured questionnaires. Adherence to Mediterranean diet (MD) was assessed by the Mediterranean Diet Score (MDS). Leukocyte LINE-1 methylation was assessed by pyrosequencing. Mediation analysis was conducted using the procedure described by Preacher and Hayes. Women with high educational level exhibited higher MDS (ß = 0.669; 95%CI 0.173-1.165; p < 0.01) and LINE-1 methylation level (ß = 0.033; 95%CI 0.022-0.043; p < 0.001) than their less educated counterpart. In line with this, mediation analysis demonstrated a significant indirect effect of high educational level on LINE-1 methylation through the adherence to MD (ß = 0.003; 95%CI 0.001-0.006). Specifically, the mediator could account for 9.5% of the total effect. To our knowledge, this is the first study demonstrating the mediating effect of diet in the relationship between SES and DNA methylation. Although these findings should be confirmed by prospective research, they add value to the promotion of healthy dietary habits in social disadvantaged people.

Hemorrhagic shock from post-traumatic rupture of microcystic splenic lymphangioma: A case report and review of the literature.

INTRODUCTION: Lymphangioma is an abnormal proliferation of lymphatic vessels. Isolated splenic lymphangioma (SL) is rare; in the last 30 years only 22 cases were reported in the literature. Diagnosis is difficult by the absence of typical symptoms and signs. SL is often asymptomatic and occasionally detected through radiological exams or, after the onset of a life-threatening complication, at surgery or pathological examination. Surgery represents the treatment of choice. PRESENTATION OF CASE: A 22-year-old Caucasian male was admitted to the Emergency Department after a car accident, complaining of sudden onset, severe, left upper quadrant abdominal pain. Abdominal examination revealed mild abdominal distention and a severe abdominal pain on superficial and deep palpation of left upper abdominal quadrant with obvious muscle guarding and rebound tenderness. Abdominal computed tomography scan showed splenic rupture with hemoperitoneum. Laboratory tests reported severe anemia. The patient received blood transfusions and was taken emergently to the operating room for exploratory laparotomy, evacuation of hemoperitoneum and splenectomy. The postoperative course was uneventful, the patient was discharged on the 7th post-operative day. Diagnosis of microcystic SL was made at pathological examination. DISCUSSION: Post-traumatic splenic rupture may be favored by the presence of a unknown and asymptomatic isolated SL. Although different types of treatment of SL are reported in the literature, splenectomy represents the treatment of choice to avoid complications. CONCLUSION: Isolated SL is difficult to diagnose and suspect because of lack of pathognomonic symptoms and specific diagnostic signs. It can be diagnosed after the onset of a life-threatening complication. Splenectomy is the preferable definitive treatment.

The "Obiettivo Antibiotico" Campaign on Prudent Use of Antibiotics in Sicily, Italy: The Pilot Phase.

The issue of antimicrobial resistance (AMR) is a focus of the World Health Organization, which proposes educational interventions targeting the public and healthcare professionals. Here, we present the first attempt at a regionwide multicomponent campaign in Sicily (Italy), called "Obiettivo Antibiotico", which aims to raise the awareness of prudent use of antibiotics in the public and in healthcare professionals. The campaign was designed by an interdisciplinary academic team, and an interactive website was populated with different materials, including key messages, letters, slogans, posters, factsheets, leaflets, and videos. The campaign was launched in November 2018 and, as of 21 December 2018, the website had a total of 1159 unique visitors, of which 190 became champions by pledging to take simple actions to support the fight against AMR. Data from social media showed that the audience was between 18 and 54 years of age, with a high proportion of female participants (64%). Interestingly, the LinkedIn page received more than 1200 followers, and Facebook 685 followers. The number of actions taken (pledges) by the audience was 458, evenly divided between experts (53%) and the general public (47%). Additional efforts are needed to reach more people, thus future efforts should focus on further promotion within the Sicilian region to sustain the engagement with the campaign.

The Effects of Diet and Dietary Interventions on the Quality of Life among Breast Cancer Survivors: A Cross-Sectional Analysis and a Systematic Review of Experimental Studies.

There is an ongoing need for solid evidence about the effects of healthy behaviors, and particularly diet, on the quality of life (QoL) among breast cancer survivors. We first conducted a cross-sectional study on 68 Italian stage I-III breast cancer survivors, to investigate the association of adherence to the Mediterranean diet (MD), physical activity and weight status with QoL. Adherence to MD and physical activity was assessed using structured questionnaires. QoL was assessed using the European Organization for the Research and Treatment of Cancer Quality-of-Life tools. We showed that low consumption of red meat and carbonated beverages, daily consumption of wine and high consumption of dishes seasoned with sofrito had beneficial effects on several QoL subscales. By contrast, using olive oil as the main culinary fat, low consumption of commercial sweets and high consumption of nuts were associated with negative effects. Overall, these findings resulted in a null effect of adherence to MD on QoL. Furthermore, we observed better QoL sub-scores among women who performed moderate physical activity (i.e., diarrhea) and those who were underweight/normal weight (i.e., physical functioning and dyspnea) if compared with their counterparts (p-values ≤ 0.003 after correction for multiple comparison). Next, we performed a systematic review of nine experimental studies to summarize whether dietary interventions might improve QoL among breast cancer patients. All the studies demonstrated significant improvements in overall QoL and/or its subscales after the interventions. However, differences in study design, interventions and tools used for QoL assessment did not allow us to provide an overall estimate. Moreover, only a single-arm trial evaluated the effect of an exclusive dietary-based intervention, while others combined dietary recommendations with physical activity and weight loss programs. For these reasons, our study encourages more efforts to improve the robustness of current evidence, through more homogenous tools, larger population-based studies and further randomized controlled trials.
