Marine reserves constitute effective tools for preserving fish stocks and associated human benefits. However, not all reserves perform equally, and predicting the response of marine communities to management actions in the long run is challenging. Our decadal-scale survey of recreational fishing yields at France's 45-year old Cerbère-Banyuls marine reserve indicated significant protection benefits, with 40-50% higher fishing yields per unit effort in the partial-protection zone of the reserve (where fishing is permitted but at a lower level) than in surrounding non-reserve areas.

Aims/hypothesis: Diabetic foot osteomyelitis is a major risk factor for amputation. Medical treatment allows remission in 53-82% of cases. However, the optimal duration of antibiotic therapy remains controversial as a validated marker of osteomyelitis remission is lacking.

Fluorine-18-fluorodeoxyglucose (F-FDG) PET/computed tomography (CT) is now a standard of care in initial staging and treatment evaluation of lymphomas. It is also used in the interim evaluation in diffuse large B cell lymphoma and Hodgkin lymphoma. However, several pitfalls may occur during or after treatment, because of the nonspecificity of F-FDG for lymphoma disease and treatment as immunotherapy, thus possibly induces misinterpretation and wrong treatment decision.

Article Synopsis
  • This study evaluated glucose metabolism in multicystic and epithelioid peritoneal mesothelioma using F-FDG-PET/ceCT and investigated its prognostic significance.
  • Twenty-three patients, free from prior treatment, underwent imaging before surgery; results indicated notable differences in glucose uptake between the two types of mesothelioma.
  • Findings revealed that lower SUVmax values and other factors correlated with better progression-free survival in patients with epithelioid mesothelioma, while multicystic patients showed no recurrences.

Objective: The aim of this study was the assessment of semi-quantified salivary gland dynamic scintigraphy (SGdS) parameters independently and in an integrated way in order to predict primary Sjögren's syndrome (pSS).

Materials And Methods: Forty-six consecutive patients (41 females; age 61 ± 11 years) with sicca syndrome were studied by SGdS after injection of 200 MBq of pertechnetate. In sixteen patients, pSS was diagnosed, according to American-European Consensus Group criteria (AECGc).

Article Synopsis
  • FDG-PET/CT is crucial for staging and assessing treatment response in Hodgkin lymphoma, but it can have interpretation pitfalls that affect treatment decisions.
  • A case study discusses a 29-year-old woman with stage III bulky Hodgkin lymphoma who initially showed a complete metabolic response on PET/CT.
  • After further chemotherapy, symptoms emerged, leading to the discovery of cat-scratch disease instead of lymphoma recurrence, highlighting the need for careful evaluation of imaging results.

Marginal zone lymphoma (MZL) is usually considered not avid for FDG. We report a case of a 57-year-old man with an MZL suspected for transformation. FDG-PET/CT showed a diffuse atypical involvement of subcutaneous fat, without sign suggestive for a transformation.

Aim: To evaluate the diagnostic performance of fluorine-18-fluorodeoxyglucose PET/computed tomography (F-FDG-PET/CT) and MRI with diffusion-weighted images (DWI) in uterine sarcomas (US).

Patients And Methods: A systematic review was performed on Medline, ISI web of knowledge, and Scopus databases for studies reporting the diagnostic performance of F-FDG-PET/CT and DWI-MRI in US published up to 15 February 2016. Exclusion criteria were articles with fewer than five cases of US, without DWI-MRI, and previous series of patients from the same researcher team.

Cancer imaging on the peritoneum is quite difficult on PET/CT because of the particular anatomical features of this membrane. The abdominal cavity can be the seat of very different primary or secondary tumoral lesions, with heterogeneous aggressiveness and variable fluorine-18 fluorodeoxyglucose uptake and patterns. We aimed to depict a spectrum of appearances with abnormal fluorine-18 fluorodeoxyglucose uptakes localized on the peritoneum in frequent conditions such as peritoneal carcinomatosis and in rarer disease such as desmoplastic round cell tumor.

Purpose: Identifying patients at high risk of progression and early death among those with high-tumor-burden follicular lymphoma (FL) is unsatisfactory with current prognostic models. This study aimed to determine the prognostic impact of the total metabolic tumor volume (TMTV) measured at baseline with [F]fluorodeoxyglucose/positron emission tomography-computed tomography ([F]FDG/PET-CT) scans and its added value to these models.

Patients And Methods: A pooled analysis was performed by using patient data and centrally reviewed baseline PET-CT scans for 185 patients with FL who were receiving immunochemotherapy within three prospective trials.

Article Synopsis
  • Pseudomyxoma peritonei (PMP) is a rare cancer linked to appendiceal tumors, and this study aimed to assess the effectiveness of FDG-PET/ceCT scans in predicting patient outcomes, specifically progression-free survival (PFS).
  • The study included 56 patients who underwent surgery and chemotherapy for PMP, evaluating FDG-PET/ceCT scans and correlating results with clinical parameters like the Peritoneal Cancer Index (PCI) and Completeness of Cytoreduction Score (CCR).
  • Findings revealed that SUVmax (a PET scan measurement) was an independent predictor for PFS but did not show a significant connection to post-operative CCR or differences based on disease spread type. Further research

Article Synopsis
  • FDG PET/CT is now recognized as an effective tool for evaluating treatment responses in patients with non-Hodgkin lymphoma.
  • A case study describes a 62-year-old man with stage III diffuse large B-cell lymphoma who underwent FDG PET/CT scans.
  • The interim scan showed complete metabolic and morphological response in lymph nodes, but also detected abnormal uptake in the abdomen, leading to a biopsy that revealed diffuse fat necrosis rather than cancer.

Purpose: Sentinel lymph node biopsy is an essential staging tool in patients with clinically localized melanoma. The harvesting of a sentinel lymph node entails a sequence of procedures with participation of specialists in nuclear medicine, radiology, surgery and pathology. The aim of this document is to provide guidelines for nuclear medicine physicians performing lymphoscintigraphy for sentinel lymph node detection in patients with melanoma.

Article Synopsis
  • The study examined how consistently different doctors interpret [(18)F]choline PET/CT scans in patients with prostate cancer that recurred after treatment.
  • It involved 60 patients and compared the interpretations of four nuclear medicine physicians who used the same methods, without knowing the patients' clinical backgrounds, two months apart.
  • The results showed moderate to excellent consistency among observers for different areas assessed, with particularly high agreement for lymphatic assessments and good reproducibility for bone metastasis evaluations.

The present article describes two novel flexible plastic-based disposable bioreactors. The first one, the WU bioreactor, is based on the principle of a wave and undertow mechanism that provides agitation while offering convenient mixing and aeration to the plant cell culture contained within the bioreactor. The second one is a high aspect ratio bubble column bioreactor, where agitation and aeration are achieved through the intermittent generation of large diameter bubbles, "Taylor-like" or "slug bubbles" (SB bioreactor).
