Usefulness of intraoperative bile culture in patients with acute calculous cholecystitis with previous biliary events: does the postoperative management change?

Eur J Clin Microbiol Infect Dis. 2023 Nov 20. doi: 10.1007/s10096-023-04713-7. Online ahead of print.

ABSTRACT

PURPOSE: The aim of our study was to determine the usefulness of intraoperative gallbladder cultures in the postoperative course in surgically treated patients with acute calculous cholecystitis and previous biliary events (ACC-PBE).

METHODS: Retrospective unicenter study on surgically treated ACC-patients between January 2014 and December 2018. Clinical benefit was defined as a > 20% change in postoperative antibiotic treatment. Secondary endpoints: postoperative morbidity and length-of-stay (LOS) in ACC-PBE patients with positive intraoperative biliary culture (IBC). Statistical significance was defined as p < 0.05.

RESULTS: Out of the initial 711 patients, 203 met the study’s inclusion criteria, with 139 of them having IBC results (72 positive, 67 negative). Our analysis revealed no significant difference in the incidence of positive-IBC between patients with ACC-PBE. Among this group, only 6% changed postoperative antibiotic treatment based on IBC results. There were no statistically significant differences in postoperative complications (p: 0.21) or LOS (p: 0.23) in the ACC-PBE group. In multivariate analysis, age > 70 years old (p: 0.00; HR 3.1, 95% IC [1.6-6.4]), prior ERCP (p: 0.02; HR 5.9, 95% IC [1.25-27.5]) and prior antibiotic treatment (p: 0.01; HR 3.6, 95% IC [1.32-9.86]) were identified as independent factors that influenced PBC.

CONCLUSIONS: IBC in operated ACC-PBE do not alter postoperative management. While positive-IBC was associated with age, prior ERCP, and prior antibiotic treatment, these findings did not have a significant impact on postoperative morbidity or LOS.

The value of MRI in quantification of parametrial invasion and association with prognosis in locally advanced cervical cancer: the “PLACE” study

Eur Radiol. 2023 Nov 20. doi: 10.1007/s00330-023-10443-3. Online ahead of print.

ABSTRACT

OBJECTIVE: This retrospective observational study aims to evaluate the association between the extent of parametrial invasion (PMI) and disease-free survival (DFS) and cancer-specific survival (CSS) in patients with locally advanced cervical cancer (LACC).

MATERIALS AND METHODS: This study included patients with LACC showing parametrial invasion at Magnetic Resonance Imaging (MRI). They were treated with neoadjuvant chemo-radiotherapy (CT/RT) before undergoing radical hysterectomy. The staging MRIs were reviewed retrospectively. Measurements of maximum PMI (PMImax) and parametrial length were taken bilaterally. After that, PMIratio was calculated by dividing PMImax by parametrial length. Analysis was conducted on homogeneous subsets of patients, grouped based on their pathological lymph nodal evaluation (N- and N+). Correlations between PMImax and PMIratio with DFS and CSS were evaluated in both the N- and N+ groups, employing univariable Cox regression analysis.

RESULTS: Out of 221 patients, 126 (57%) had non-metastatic lymph nodes (N-), while 95 (43%) had metastatic lymph nodes (N+). The median observation period for all these patients was 73 months (95% confidence interval [CI]: 66-77). The 5-year DFS and CSS probability rates were 75% and 85.7%, respectively, for the N- group and 54.3% and 73.6%, respectively, for the N+ group. A higher PMImax (hazard ratio [HR] = 1.09) and PMIratio (HR = 1.04) correlated with worse overall survival in patients in the N- group (p = 0.025 and p = 0.042). These parameters did not show a significant statistical association in the N+ group.

CONCLUSIONS: The degree of PMI evaluated on MRI affects outcome in N- patients with LACC.

CLINICAL RELEVANCE STATEMENT: The degree of MRI parametrial invasion affects disease-free survival and cancer-specific survival in patients with the International Federation of Gynecology and Obstetrics (FIGO) stage IIB cervical cancer. This MRI finding can be easily incorporated into routine clinical practice.

KEY POINTS: • Visual assessment of parametrial invasion on MRI was not significantly associated with prognosis in locally advanced cervical cancer (LACC). • A greater degree of parametrial invasion is associated with poorer disease-free survival and cancer-specific survival in patients with LACC without metastatic lymph node involvement. • The degree of parametrial invasion at MRI has no correlation with prognosis in LACC with metastatic lymph nodes.

Head-to-head comparison of prostate-specific membrane antigen PET and multiparametric MRI in the diagnosis of pretreatment patients with prostate cancer: a meta-analysis

Eur Radiol. 2023 Nov 20. doi: 10.1007/s00330-023-10436-2. Online ahead of print.

ABSTRACT

OBJECTIVES: To compare prostate-specific membrane antigen (PSMA) PET with multiparametric MRI (mpMRI) in the diagnosis of pretreatment prostate cancer (PCa).

METHODS: Pubmed, Embase, Medline, Web of Science, and Cochrane Library were searched for eligible studies published before June 22, 2022. We assessed risk of bias and applicability by using QUADAS-2 tool. Data synthesis was performed with Stata 17.0 software, using the “midas” and “meqrlogit” packages.

RESULTS: We included 29 articles focusing on primary cancer detection, 18 articles about primary staging, and two articles containing them both. For PSMA PET versus mpMRI in primary PCa detection, sensitivities and specificities in the per-patient analysis were 0.90 and 0.84 (p<0.0001), and 0.66 and 0.60 (p <0.0001), and in the per-lesion analysis they were 0.79 and 0.78 (p <0.0001), and 0.84 and 0.82 (p <0.0001). For the per-patient analysis of PSMA PET versus mpMRI in primary staging, sensitivities and specificities in extracapsular extension detection were 0.59 and 0.66 (p =0.005), and 0.79 and 0.76 (p =0.0074), and in seminal vesicle infiltration (SVI) detection they were 0.51 and 0.60 (p =0.0008), and 0.93 and 0.96 (p =0.0092). For PSMA PET versus mpMRI in lymph node metastasis (LNM) detection, sensitivities and specificities in the per-patient analysis were 0.68 and 0.46 (p <0.0001), and 0.91 and 0.90 (p =0.81), and in the per-lesion analysis they were 0.67 and 0.36 (p <0.0001), and 0.99 and 0.99 (p =0.18).

CONCLUSION: PSMA PET has higher diagnostic value than mpMRI in the detection of primary PCa. Regarding the primary staging, mpMRI has potential advantages in SVI detection, while PSMA PET has relative advantages in LNM detection.

CLINICAL RELEVANCE STATEMENT: The integration of prostate-specific membrane antigen (PSMA) PET into the diagnostic pathway may be helpful for improving the accuracy of prostate cancer detection. However, further studies are needed to address the cost implications and evaluate its utility in specific patient populations or clinical scenarios. Moreover, we recommend the combination of PSMA PET and mpMRI for cancer staging.

KEY POINTS: • Prostate-specific membrane antigen PET has higher sensitivity and specificity for primary tumor detection in prostate cancer compared to multiparametric MRI. • Prostate-specific membrane antigen PET also has significantly better sensitivity and specificity for lymph node metastases of prostate cancer compared to multiparametric MRI. • Multiparametric MRI has better accuracy for extracapsular extension and seminal vesicle infiltration compared to ate-specific membrane antigen PET.

Characterization of the congenital diaphragmatic hernia model in C57BL/6J fetal mice: a step toward lineage tracing experiments

Pediatr Surg Int. 2023 Nov 20;39(1):296. doi: 10.1007/s00383-023-05583-y.

ABSTRACT

PURPOSE: Lineage tracing is key to study the fate of individual cells and their progeny especially in developmental biology. To conduct these studies, we aimed to establish a reproducible model of CDH in the most commonly used genetic background strain that is C57BL/6J mice.

METHODS: CDH was induced in C57BL/6J dams by maternal administration of nitrofen + bisdiamine at E8.5. Fetuses from olive oil-gavaged mothers served as controls. Lungs from CDH and control fetuses were compared for (1) growth via radial airspace count (RAC), mean linear intercept (MLI) and gene expression for Fgf10, Nrp1, and Ctnnb1; (2) maturation (Pdpn, Spc, Ager, Abca3, Eln, Acta2, Pdgfra) via gene and protein expression; (3) vascularization via gene and protein expression (CD31, Vegfa, Vegfr1/2, Epas1, Enos).

STATISTICS: unpaired t-test or Mann-Whitney test.

RESULTS: Nitrofen + bisdiamine administration resulted in 36% left-sided CDH (31% mortality). CDH fetuses had hypoplastic lungs and impaired growth (lower RAC, higher MLI, lower Fgf10, Nrp1, Ctnnb1), maturation (decreased Pdpn, Ager, Eln gene expression), and vascularization (decreased Cd31, Vegfr1/2; Epas1 and Enos). Lower protein expression was confirmed for PDPN, ELN and CD31.

CONCLUSION: Modeling CDH in C57BL/6J mouse fetuses is effective in reproducing the classical CDH hallmarks. This model will be critical for lineage tracing experiments.

Effectiveness of high-intensity laser therapy in the treatment of patients with frozen shoulder: a systematic review and meta-analysis

Lasers Med Sci. 2023 Nov 20;38(1):266. doi: 10.1007/s10103-023-03901-3.

ABSTRACT

The purpose of this study is to evaluate the effects of high-intensity laser therapy (HILT) in patients with frozen shoulder. PRISMA guidelines were adhered to, and a systematic search was conducted in the PubMed, Web of Science, Scopus, CINAHL, Science Direct, and PEDro databases (last update: September 4, 2023; search period: December 2022-September 2023). The inclusion criteria encompassed RCTs comparing HILT with other physical therapy interventions in frozen patients with frozen shoulders, with or without sham HILT, assessing pain intensity, shoulder ROM, and disability outcomes. The quality of the RCTs was assessed with the Cochrane Risk of Bias tool, and evidence was assessed using the GRADE approach. Five trials met the eligibility criteria and were included in the review and meta-analysis, which pooled results from the visual analog scale (VAS), goniometry, and the shoulder pain and disability index (SPADI). Mean differences (MDs) for pain intensity and disability show a pooled effect in favor of HILT both for VAS (MD = – 2.23 cm, 95% CI: – 3.25, – 1.22) and SPADI (MD = – 10.1% (95% CI = – 16.5, – 3.7), changes that are statistical (p < 0.01) and clinical. The MD for flexion (MD = 9.0°; 95% CI: – 2.36°, 20.3°; p = 0.12), abduction (MD = 3.4°; 95% CI: – 6.9°, 13.7°; p = 0.51), and external rotation (MD = – 0.95°; 95% CI: – 5.36°, 3.5°; p = 0.67) does not show statistical and clinical differences between groups after treatment. PI and disability changes were graded as important due to their clinical and statistical results. HILT into a physical therapy plan reduce pain and disability, but it does not outperform conventional physical therapy in improving shoulder ROM. It is suggested that future RCTs compare the effects of HILT and LLLT to assess their possible differences in their analgesic effects.

Impact of the COVID-19 Pandemic on Complex Aortic Aneurysm Surgery

J Endovasc Ther. 2023 Nov 19:15266028231210214. doi: 10.1177/15266028231210214. Online ahead of print.

ABSTRACT

INTRODUCTION: This study aimed to evaluate the impact of COVID on total case load and peri-operative outcomes in patients undergoing open surgical repair (OSR) and endovascular repair (ER) of complex aortic aneurysms (cAAs).

METHODS: A single-center retrospective analysis of prospective data of patients managed with elective cAA ER or OSR from January 2018 to December 2021 was conducted. A comparative analysis on the impact of the COVID-19 pandemic on the case volume and on the 30-day outcomes was assessed using time periods, before (2018-2019) and during the pandemic (2020-2021).

RESULTS: During the 4-year study period, 255 patients with cAA were managed with ER and 576 with OSR. The pandemic did not reduce the cAA ER volume (p=0.12), but a statistically significant reduction in OSR case load was recorded (p=0.04). Following OSR, hospital length of stay (11.1 vs 10.3 days), and early mortality (6.94% vs 4.63%), were similar before and during the pandemic. In the ER cohort, baseline characteristics, early mortality (3.6% vs 4.1%, p=0.976), and morbidity (10% vs 14%, p=0.44), were comparable during the 2 periods. For ER cases, the hospital and intensive care unit (ICU) stay both decreased significantly (8±8-6±7 days, p<0.001 and 2±4 vs 1±6 days p=0.01, respectively) during the pandemic.

CONCLUSION: Resource pressures drove modifications in clinical practice to reduce the length of hospitalization, without compromising the clinical outcomes, in patients undergoing ER of cAA. This modification was not effective in patients undergoing OSR that resulted in a significant decrease of this activity.

CLINICAL IMPACT: The pandemic did not reduce complex endovascular repair (ER) volume (p=0.12) while a significant reduction in open surgical repair (OSR) case load was recorded (p=0.04). For the endovascular cohort, early mortality (p=0.976) and morbidity (p=0.44) remained stable, while the hospital and intensive care unit (ICU) stay decreased (p<0.001 and p=0.01, respectively) during the pandemic.

An Experimental Test of the Effects of Public Mockery of a Social Media Health Campaign: Implications for Theory and Health Organizations’ Social Media Strategies

Health Commun. 2023 Nov 19:1-13. doi: 10.1080/10410236.2023.2282833. Online ahead of print.

ABSTRACT

This study explored how social media users’ mocking of a public health campaign can affect other users’ emotions, cognitions, and behavioral intentions. Inspired by public mocking of the CDC’s “Say No to Raw Dough” campaign aiming to prevent food poisoning caused by eating raw flour-based products, this experiment (N = 681) employed a 2 (Public responses to a PSA: Mocking or serious) x 3 (Organizational response to public responses: Self-mocking, serious, or none) + 1 (control condition) design. Statistical tests revealed that user-generated mocking can lower intentions to avoid the health risk by decreasing perceptions of injunctive norms (that is, seeing others mock a public health campaign resulted in weaker perceptions that others think you should avoid the risky behavior). Mockery of a public health campaign also engender anger at the CDC and at other users, with the target of the anger having differential effects on intentions to avoid eating raw dough. Implications for theory and the practice of social media-based health promotion are discussed.

Analysis of non-motor symptoms in amyotrophic lateral sclerosis

Amyotroph Lateral Scler Frontotemporal Degener. 2023 Nov 19:1-5. doi: 10.1080/21678421.2023.2280618. Online ahead of print.

ABSTRACT

OBJECTIVE: We investigated non-motor symptoms in ALS using sequential questionnaires; here we report the findings of the second questionnaire.

METHODS: A social media platform (Twitter, now known as X) was used to publicize the questionnaires. Data were downloaded from SurveyMonkey and analyzed by descriptive statistics, comparison of means, and regression models.

RESULTS: There were 182 people with ALS and 57 controls. The most important non-motor symptoms were cold limbs (60.4% cases, 14% controls, p = 9.67 x 10-10) and appetite loss (29.7% cases, 5.3% controls, p = 1.6 x 10-4). The weaker limb was most likely to feel cold (p = 9.67 x 10-10), and symptoms were more apparent in the evening and night. Appetite loss was reported as due to feeling full and the time taken to eat. People with ALS experienced medium-intensity pain, more usually shock-like pain than burning or cold-like pain, although the most prevalent type of pain was non-differentiated.

CONCLUSIONS: Non-motor symptoms are an important feature of ALS. Further investigation is needed to understand their physiological basis and whether they represent phenotypic differences useful for subtyping ALS.

The unfunded grant, now what? Advice, approach, and strategy

Surgery. 2023 Nov 17:S0039-6060(23)00745-6. doi: 10.1016/j.surg.2023.09.057. Online ahead of print.

ABSTRACT

BACKGROUND: Grant writing takes significant time and effort and often may be elusive, especially on a first attempt. After the rejection of a grant, many investigators face a dilemma regarding the best next steps. In this article, we discuss the options of revision versus resubmission and how to navigate these decisions.

METHODS: The literature was surveyed, including review articles, personal perspectives, and editorial pieces regarding the grant writing and funding processes. The National Institute of Health database was reviewed, and data were extrapolated from the past 10 years of funding percentages and rates of both R01 initial applications and resubmissions. Recommendations were then generated based on pertinent literature and experience from the authors.

RESULTS: The grant writing process involves many checkpoints between conception and funding. Only approximately 15% of R01 and R01-equivalent grants are accepted for funding on the initial submission. However, this statistic increases to >30% if the appropriate steps are taken to revise and resubmit the grant. These steps include consulting co-investigators, modifying hypotheses, drafting a succinct “Introduction” document, and many more. Knowing the options after the rejection of an original submission plays a huge role in the ultimate success of the grant.

CONCLUSION: Although receiving funding for an original grant can be difficult, with appropriate guidance, it may seem more feasible than initially expected. Adequately responding to the critiques of the grant and revising the grant appropriately can make or break the outcome of the grant.

Retrograde Intrarenal Surgery for Renal Stones: Is It a Safe and Effective Option in Preschool Children?

J Pediatr Surg. 2023 Oct 28:S0022-3468(23)00666-8. doi: 10.1016/j.jpedsurg.2023.10.056. Online ahead of print.

ABSTRACT

INTRODUCTION: Few studies in the literature describe the Retrograde Intra-Renal Surgery (RIRS) outcome in preschool children. We evaluated the feasibility, stone-free rate and complications of RIRS in preschool children at two European tertiary care centres of Pediatric Urology.

MATERIAL AND METHODS: The retrospective study includes all children undergone RIRS for stones <25 mm from 2017 to 2022. Patients were divided into Group 1 <5 years (G1) and Group 2 >5 years (G2). Semirigid ureterorenoscope 4.5-6.5 Ch and a 7.5 Fr flexible ureteroscope with a 9.5/11 Ch ureteral access sheath (UAS) were used. Stone-free rate (SFR) was evaluated at 3 months. Fischer/Chi-square test for qualitative data and Mann-Whitney for quantitative data were used for statistical analysis.

RESULTS: 63 patients underwent RIRS, 19 G1-patients, median age 3.55 ± 1.06 years (range 1.5-5 years), and 44 G2-patients, median age 11.25 ± 2.95 (range 6-17 years) (p < 0.00001). Intraoperative complications occurred in 1 case in G1(5%) and 3 in G2(7%) (p = 1): two minor ureteric injuries in G2 were treated by a prolonged JJ-stent. Postoperative fever was reported in 3 cases in G1 (16%) and 4 in G2(9%) (p = 0.42), while post-operative hematuria in 4 G1-patients (21%) and in 7 G2-patients (16%) (p = 0.72). SFR was 84.2% in G1 and 88.6% in G2. At an average follow-up of 15.05 ± 4.83 months in G1 and 19.95 ± 10.36 months in G2, reintervention for residual stones was necessary in 3 cases in G1(16%) and in 6 cases in G2(14%) (p = 1).

CONCLUSIONS: In a European country with low-volume pediatric stone centers, RIRS is a promising therapeutic option in young children as it offers acceptable stone-free rate and a low incidence of high-grade complications.
