A classical analog of the quantum Zeeman effect.

We extend a recent classical mechanical analog of Bohr's atom consisting of a scalar field coupled to a massive point-like particle [P. Jamet and A. Drezet, "A mechanical analog of Bohr's atom based on de Broglie's double-solution approach," Chaos 31, 103120 (2021)] by adding and studying the contribution of a uniform weak magnetic field on their dynamics.

Primary Gastrointestinal Follicular Lymphomas: A Prospective Study of 31 Patients with Long-term Follow-up Registered in the French Gastrointestinal Lymphoma Study Group (GELD) of the French Federation of Digestive Oncology (FFCD).

Background/aims: Primary gastrointestinal follicular lymphomas (PGFL) are very rare. Our aim was to analyze the clinical features, management, and long-term outcomes in a prospective series of patients diagnosed with PGFL.

Methods: All adult patients with PGFL, consecutively enrolled into the multicenter French study between 1990 and 2017, were evaluated and followed up prospectively after undergoing a complete work-up.

Mechanical analog of quantum bradyons and tachyons.

We present a mechanical analog of a quantum wave-particle duality: a vibrating string threaded through a freely moving bead or "masslet." For small string amplitudes, the particle movement is governed by a set of nonlinear dynamical equations that couple the wave field to the masslet dynamics. Under specific conditions, the particle achieves a regime of transparency in which the field and the particle's dynamics appear decoupled.

Comparison of the removal of uraemic toxins with medium cut-off and high-flux dialysers: a randomized clinical trial.

Background: Accumulation of middle-weight uraemic toxins in haemodialysis (HD) patients results in increased morbidity and mortality. Whether medium cut-off HD (MCO-HD) improves removal of middle-weight uraemic toxins remains to be demonstrated.

Methods: This cross-over prospective study included 40 patients randomly assigned to receive either 3 months of MCO-HD followed by 3 months of high-flux HD (HF-HD), or vice versa.

Gastric MALT lymphoma in a population-based study in France: clinical features, treatments and survival.

Background: Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is a rare disease, and most available data on gastric MALT lymphoma (GML) come from clinical studies of selected patients treated in centres of excellence.

Aims: To analyse the clinical features, management and survival of GML patients in a population-based study in France METHODS: All new cases of GML diagnosed between 2002 and 2010 in 11 French areas covered by cancer registries were included. Pathology reports were verified and, if necessary, reviewed by an expert pathologist.

Large amplitude motion within acetylene-rare gas complexes hosted in helium droplets.

Near-infrared spectroscopy of the C2H2-Ar, Kr complexes was performed in the spectral region overlapping the ν3/ν2 + ν4 + ν5 Fermi-type resonance of C2H2. The experiment was conducted along the HElium NanoDroplet Isolation (HENDI) technique in order to study the coupling dynamics between a floppy molecular system (C2H2-Ar and C2H2-Kr) and a mesoscopic quantum liquid (the droplet). Calculations were performed using a spectral element based close-coupling program and state-of-the-art 2-dimensional potential energy surfaces to determine the bound states of the C2H2-Ar and C2H2-Kr complexes and simulate the observed spectra.

Primary intestinal B-cell lymphoma: a prospective multicentre clinical study of 91 cases.

Background & Aims: Clinical presentation, diagnosis and prognosis of different primary intestinal lymphomas have not been well described and compared so far. Our aim was to prospectively analyse a series of consecutive patients presenting different types of B-cell primary intestinal lymphomas.

Methods: Adult patients with primary intestinal lymphoma, collected between 1991 and 2000 within the multicenter national study in France were evaluated and followed up prospectively.

[Use of indicators of fluid responsiveness in septic shock: a survey in public emergency departments].

Introduction: Fluid therapy is one of the major elements of severe sepsis and septic shock management. A systematic initial fluid bolus is recommended before evaluation of left ventricular filling pressure by the use of indicators of fluid responsiveness, preferentially dynamic ones. A massive fluid therapy could be damaging for the patient.

Delineation of the infrequent mosaicism of KRAS mutational status in metastatic colorectal adenocarcinomas.

This study addresses the extent of the heterogeneity of KRAS status, present in a minority of metastatic colorectal carcinomas (mCRCs), on the basis of a thorough analysis of surgical resection specimens. Eighteen patients with mCRC were included. KRAS mutations (exon 2, codons 12 and 13) were determined using PCR and subsequent direct sequencing.

High relapse rate among lepromatous leprosy patients treated with rifampin plus ofloxacin daily for 4 weeks.

Fifty-one lepromatous leprosy patients, all of whom had relapsed after previous dapsone (DDS) monotherapy, were treated between 1990 and 1991 with 600 mg of rifampin (RMP) plus 400 mg of ofloxacin (OFLO) daily for 4 weeks, and the great majority of the patients were followed up at least once a year after completion of the treatment. After only 173 patient-years of follow-up, 5 relapses had been detected; the overall relapse rate was 10.0% (confidence limits, 1.

Effect of HIV infection on leprosy: a three-year survey in Bamako, Mali.

From February 1992 until June 1994, all patients with histologically proven leprosy examined at the Leprology Unit of the Institut Marchoux in Bamako, Mali, were screened for HIV serology. In total, 740 leprosy patients have been tested; 553 known, previously treated leprosy cases and 187 new cases, mainly self-reporting and referred cases. The global seroprevalence in the sample was 1.

Bactericidal activity of single dose of clarithromycin plus minocycline, with or without ofloxacin, against Mycobacterium leprae in patients.

Fifty patients with newly diagnosed lepromatous leprosy were allocated randomly to one of five groups and treated with either a month-long standard regimen of multidrug therapy (MDT) for multibacillary leprosy, a single dose of 600 mg of rifampin, a month-long regimen with the dapsone (DDS) and clofazimine (CLO) components of the standard MDT, or a single dose of 2,000 mg of clarithromycin (CLARI) plus 200 mg of minocycline (MINO), with or without the addition of 800 mg of ofloxacin (OFLO). At the end of 1 month, clinical improvement accompanied by significant decreases of morphological indexes in skin smears was observed in about half of the patients of each group. A significant bactericidal effect was demonstrated in the great majority of patients in all five groups by inoculating the footpads of mice with organisms recovered from biopsy samples obtained before and after treatment.

[Anatomopathologic study of five cases of leprosy in HIV seropositive patients].

In an effort to establish whether the human immunodeficiency virus (HIV) modifies the histological image of lepromatous skin lesion, a comparative study was conducted in 1994 at the Marchoux Institute in Bamako, Mali, on persons newly suffering from leprosy who had been tested seropositive and seronegative for the HIV virus. These new leprosy patients had never been treated and could be grouped as follows: 5 HIV-positive (1 TT, 1 BT, 1 BL, 2 LL) and 10 controls testing HIV-negative, selected according to the following criteria: each seropositive leprosy subject was matched with two seronegative controls having the same clinical features, same stage under the Ridley classification system, same age and sex. No discordance between the clinical classifications and the histological features in the subjects testing HIV-positive has been observed.

Relapse after long-term follow up of multibacillary patients treated by WHO multidrug regimen. Marchoux Chemotherapy Study Group.

Thirty-five multibacillary (MB) leprosy patients were treated with 2 years of multidrug therapy (MDT) and followed up regularly for relapse. Relapse was defined as: a) an increase of the bacterial index (BI) by 2+ over the previous value from any single site of old lesions and b) the occurrence of definite new skin lesion(s) which demonstrated a higher BI than any pre-existing lesion. After a mean duration of 72.

Relapses after a single dose of rifampin in skin-smear negative multibacillary patients after dapsone monotherapy.

Between 1982 and 1985, a single 1500 mg dose of rifampin (RMP) was given to 136 multibacillary leprosy patients who had become clinically inactive and skin-smear negative after various durations of dapsone monotherapy, and then antileprosy chemotherapy was totally stopped. By the end of June 1992, 15 relapses were detected among these patients. The overall relapse rate was 11%; the relapse rate per 100 patient-years was 2.

Powerful bactericidal activities of clarithromycin and minocycline against Mycobacterium leprae in lepromatous leprosy.

Thirty-six patients with newly diagnosed lepromatous leprosy were allocated randomly to three groups and treated for 56 days with minocycline (100 mg daily), clarithromycin (500 mg daily), or clarithromycin (500 mg) plus minocycline (100 mg daily). All groups had rapid and remarkable clinical improvement and significant decline of the bacterial and morphologic indices in skin smears during treatment. More than 99% and > 99.

Short-term trial of clofazimine in previously untreated lepromatous leprosy.

Forty-five previously untreated lepromatous leprosy patients were allocated randomly to three groups and treated, respectively, with Regimen A, standard dosage of clofazimine (CLO) in multidrug therapy (MDT) regimen; Regimen B, CLO 600 mg once every 4 weeks; and Regimen C, CLO 1200 mg once every 4 weeks. The duration of the trial was 24 weeks. By the end of the trial, although a few patients in each group did not improve at all clinically, the majority of patients showed clinical amelioration but the responses were slow.

Relapses in multibacillary leprosy patients after stopping treatment with rifampin-containing combined regimens. Marchoux Chemotherapy Study Group.

During the decade between the mid 1970s and the mid-1980s, 12 rifampin (RMP)-containing combined regimens were tested among lepromatous leprosy patients in the Institut Marchoux. The 384 patients who were seen at least once during the period beginning 12 months after completion of treatment were considered eligible for analysis of the relapse rate. By the end of May 1991, relapse, manifested by a significant increase of the bacterial index (BI) and the appearance of new lesions with a BI greater than that of preexisting lesions, had been observed in 68 (17.
