Clinical effectiveness of a new oral curcumin formulation in acute non-infectious uveitic macular edema: a 12-month observational study.

OBJECTIVE: Oral supplementation with curcumin demonstrated a beneficial effect on some ocular diseases, including uveitis and macular edema. This study aimed to evaluate the effectiveness and safety of a curcumin formulation with the hydrophilic carrier (CHC; Diabec®, Alfa Intes, Italy) as an adjuvant to standard steroid treatment in adults suffering from acute non-infectious uveitic macular edema (NIUME). PATIENTS AND METHODS: This was a monocenter prospective observational study carried out between January 2019 and May 2020 on consecutive patients with a new diagnosis of NIUME. Patients were treated with standard therapy or with a CHC add-on to standard treatment. The observation period for each patient was 12 months. The Best Corrected Visual Acuity (BCVA) and the Central Macular Thickness (CMT) were the primary outcomes; Foveal Avascular Zone (FAZ) and intraocular pressure (IOP) were also assessed, along with safety data. RESULTS: A total of 43 eyes of 26 patients were analyzed. CHC-treated eyes showed an improvement in mean BCVA from baseline (0.34 logMar) to T6 (0.20 logMar) and T12 (0.19 logMar; p≤0.05 and p≤0.01, respectively); CMT decreased from a mean of 320 µm (T0) to 278 µm (T6; p≤0.05) and 272 µm (T12; p≤0.01). A significant improvement of mean BCVA in the CHC group at T6 and T12 was reported compared to the control group (p≤0.01). FAZ and IOP showed no statistically significant variations in both groups. No adverse events were recorded. CONCLUSIONS: CHC as an adjuvant treatment improved the anatomical and functional outcomes, without significant side effects in eyes affected by the recent onset of NIUME, compared to the sole standard therapy.

An updated Italian normative dataset for the Stroop color word test (SCWT).

The Stroop color and word test (SCWT) is widely used to evaluate attention, information processing speed, selective attention, and cognitive flexibility. Normative values for the Italian population are available only for selected age groups, or for the short version of the test. The aim of this study was to provide updated normal values for the full version, balancing groups across gender, age decades, and education. Two kinds of indexes were derived from the performance of 192 normal subjects, divided by decade (from 20 to 90) and level of education (4 levels: 3-5; 6-8; 9-13; >13 years). They were (i) the correct answers achieved for each table in the first 30 s (word items, WI; color items, CI; color word items, CWI) and (ii) the total time required for reading the three tables (word time, WT; color time, CT; color word time, CWT). For each index, the regression model was evaluated using age, education, and gender as independent variables. The normative data were then computed following the equivalent scores method. In the regression model, age and education significantly influenced the performance in each of the 6 indexes, whereas gender had no significant effect. This study confirms the effect of age and education on the main indexes of the Stroop test and provides updated normative data for an Italian healthy population, well balanced across age, education, and gender. It will be useful to Italian researchers studying attentional functions in health and disease.

A normative study of the Italian printed word version of the free and cued selective reminding test.

According to the new research criteria for the diagnosis of Alzheimer's disease, episodic memory impairment, not significantly improved by cueing, is the core neuropsychological marker, even at a pre-dementia stage. The FCSRT assesses verbal learning and memory using semantic cues and is widely used in Europe. Standardization values for the Italian population are available for the colored picture version, but not for the 16-item printed word version. In this study, we present age- and education-adjusted normative data for FCSRT-16 obtained using linear regression techniques and generalized linear model, and critical values for classifying sub-test performance into equivalent scores. Six scores were derived from the performance of 194 normal subjects (MMSE score, range 27-30, mean 29.5 ± 0.5) divided per decade (from 20 to 90), per gender and per level of education (4 levels: 3-5, 6-8, 9-13, >13 years): immediate free recall (IFR), immediate total recall (ITR), recognition phase (RP), delayed free recall (DFR), delayed total recall (DTR), Index of Sensitivity of Cueing (ISC), number of intrusions. This study confirms the effect of age and education, but not of gender on immediate and delayed free and cued recall. The Italian version of the FCSRT-16 can be useful for both clinical and research purposes.

Disodium clodronate in the treatment of pain due to bone metastases.

Disodium clodronate (dichloromethylene bisphosphonate) a drug belonging to the class of bisphosphonates, inhibits osteoclastic bone resorption and therefore it may be used in the palliative treatment of patients affected by osteolytic bone metastases. The authors have evaluated the activity and tolerability of disodium clodronate in providing pain relief and improving the quality of life in patients with bone metastases, who were not improved by radiotherapy or chemotherapy. Out of 37 patients, 32 could be evaluated for pain relief. Of these, 62.5% had their pains improved by disodium clodronate administration without regard to the type of ongoing analgesic therapy, which had no implications on the outcome of the treatment.

[Proteolytic occurrences in the metabolism of cartilage and their modification by antirheumatics]. / Proteolytische Abläufe im Knorpelstoffwechsel und ihre Beeinflussung durch Antirheumatika.

Rheumatic diseases are characterized by the progressive loss of articular cartilage. According to a well established hypothesis proteolytic enzymes take part in these events. The initial attack in an normal cartilage can be exerted by proteoglycanases originating from either chondrocytes or cells from outside the cartilage like neutrophilic granulocytes or macrophages. In rheumatoid arthritis these latter cells are found in immediate vicinity to cartilage and it is assumed that they release their enzymes directly into the cartilage. Lysosomal elastase from neutrophilic granulocytes is a key enzyme made responsible for the degradation of cartilage, since it is able to soften up this tissue and thereby to deprive it of its normal mechanical properties. Therefore the pharmacological inactivation of elastase bears a therapeutic potential for rheumatic joint disease. The ultimate value of enzyme inhibitory antirheumatic drugs needs, however, further investigation since also enzyme independent variables play an important role in maintaining normal function of cartilage.
