The epidemiology of Toxocara infection in rural Mexico is largely unknown. Therefore, we sought to determine the seroprevalence of Toxocara infection in rural people in a northern Mexican state. We performed a cross-sectional seroprevalence study of 641 people living in rural Durango State including 282 subjects of the general population, 214 subjects of Huichol ethnicity, and 145 subjects of Mennonite ethnicity. Sera of participants were analyzed for the presence of anti-Toxocara immunoglobulin G (IgG) antibodies using a commercially available enzyme immunoassay. Three (0.5%) of the 641 subjects tested were positive for anti-Toxocara IgG antibodies. Of the 3 Toxocara seropositive subjects, two were females, aged 19 and 39 years, and one was male, aged 59 years. They had contacted with dogs, cleaned cat excrement, consumed unwashed raw fruits, contacted soil, or lived in a house with soil floors. Seroprevalence of Toxocara infection was similar among the 3 groups of population studied: 0.4% for the general population, 0.9% for Huicholes, and 0.0% for Mennonites (P = 0.41). In conclusion, the Toxocara seroprevalence found in subjects in rural Durango is low as compared with those reported in people from rural areas in other countries.

The first example of an alkyl–aryl Negishi coupling in a practical, sustainable, and high-yielding process using a silica-supported catalyst in flow is described. Excellent conversions and good functional group compatibility were obtained under very mild conditions. Functionalized alkyl groups were also introduced to provide access to synthetically useful molecules and to demonstrate the versatility of the method. The scalability was assessed, and a throughput of 7.5 mmol/h of processed substrate was achieved. All crude products were free from phosphine derivatives and ready for use in subsequent reaction steps.

Purpose: This study aimed to determine the seroprevalence and correlates of Leptospira IgG antibodies in backyard pigs in the northern Mexican state of Durango. We performed a cross-sectional study of 305 backyard pigs. Anti-Leptospira IgG antibodies were detected using microscopic agglutination assay (MAT) with a panel of 12 Leptospira antigens.

Results: Overall, antibodies against Leptospira (any of the 12 Leptospira serovars examined) were found in 186 (61.0%) of the 305 pigs studied. Seropositive pigs were found on 80 (70.2%) of the 114 properties surveyed. The predominant serovar was Leptospira interrogans Pomona (n = 55); followed by Leptospira noguchii Lousiana and Leptospira santarosai Tarassovi (n = 53 each); L. interrogans Bataviae (n = 47); Leptospira biflexa Semaranga and L. interrogans Hebdomadis (n = 36 each); L. interrogans Pyrogenes (n = 30); L. interrogans Djasiman (n = 20); Leptospira borgpetersenii Ballum (n = 11); L. noguchii Panama and L. interrogans Canicola (n = 5 each); and L. borgpetersenii Mini (n = 2). Logistic regression showed that seropositivity was associated with low (<1000 m above sea level) altitude (odds ratio [OR] = 3.24; 95% confidence interval [CI]: 2.01–5.20; P < 0.001).

Conclusions: This is the first report of Leptospira exposure in backyard pigs in Mexico and of an association between Leptospira exposure in pigs and altitude. Backyard pigs represent a high-risk group for Leptospira exposure.

Background and aims

Ibogaine is a natural alkaloid that has been used in the last decades as an adjuvant for the treatment of opiate withdrawal. Despite the beneficial results suggested by animal studies and case series, there is a lack of clinical trials to assess the safety and efficacy of ibogaine. Moreover, the majority of reports described cases of heroin-dependent individuals, with and without concomitant use of methadone, using high doses of ibogaine. Therefore, it is not clear if ibogaine at low doses could be used therapeutically in people on methadone maintenance treatments (MMT).


Case report of a female on MMT for 17 years who performed a self-treatment with several low and cumulative doses of ibogaine over a 6-week period.


The patient successfully eliminated her withdrawals from methadone with ibogaine. Each administration of ibogaine attenuated the withdrawal symptoms for several hours, and reduced the tolerance to methadone until all signs of withdrawal symptoms disappeared at the end of the treatment. No serious adverse effects were observed, and at no point did the QTc measures reach clinically significant scores. Twelve months after the treatment, she was no longer on MMT.


To our knowledge, this is the first case report describing an ibogaine treatment using low and cumulative doses in a person on MMT. Although preliminary, this case suggests that low and cumulative doses of ibogaine may reduce withdrawal symptoms in patients undergoing MMT.

The link between Toxoplasma gondii infection and multiple sclerosis remains controversial. In the present study, we aimed to determine the association between T. gondii seropositivity and multiple sclerosis. Using an age- and gender-matched case-control study, we studied 45 patients who had multiple sclerosis attended in two public hospitals and 225 control subjects without this disease and other neurological disorders in Durango City, Mexico. Serum samples of cases and controls were analyzed for detection of anti-Toxoplasma IgG using a commercially available enzyme-linked immunoassay. One (2.22%) of the 45 patients with multiple sclerosis, and 15 (6.67%) of the 225 control subjects without this disease were seropositive for anti-T. gondii IgG antibodies. No statistically significant difference (OR = 0.31; 95% CI: 0.04–2.47; P = 0.48) in seroprevalence of anti-T. gondii IgG antibodies between cases and controls was found. The frequency of T. gondii seropositivity did not vary among cases and controls about sex or age groups. Results of this study do not support an association between seropositivity to T. gondii and multiple sclerosis. However, additional research with larger sample sizes to confirm this lack of association should be conducted.

Munkánk célja a Guardien Angel (GA, azaz Őrangyal) pezsgőpor véralkoholszintet befolyásoló hatásának vizsgálata volt egészséges önkénteseken. Az összeállított protokoll szerint két méréssorozatot készítettünk, amelynek során (modellezve egy családi vagy társadalmi összejövetel étkezési, ivási szokásait) 70 g tiszta szesznek megfelelő alkoholmennyiséget kellett a vizsgált személyeknek elfogyasztani egy bőséges étkezéssel párosítva. A vizsgálatban részt vevők először nem kaptak GA pezsgőport az étel-ital mellé, míg a második sorozatban közvetlenül a vizsgálat megkezdése előtt és étkezés közben 1-1 tasak, vízben oldott granulátumot ittak meg. Az önkontrollos kísérleti körülmények között végzett vizsgálat során az önkéntesektől óránként, összesen ötször vettünk vért véralkohol-meghatározás céljából. A méréseket gőztérből vett mintavételezéssel, szilárd fázisú mikroextrakciós (SPME) módszerrel, GC-MS eljárással végeztük el. A sorozatmérések eredményei alapján megállapítható, hogy a véralkoholszint a két tasak granulátum elfogyasztása után jóval alacsonyabb volt a pezsgőpor nélküli alkoholfogyasztáshoz képest. A GA pezsgőpor hatására a vizsgálat második órájától kezdve mindenkinek jelentősen csökkent a véralkoholszintje. Ez az eredmény arra utal, hogy a GA pezsgőpor véralkoholszintet csökkentő képességét az egészséges személyek egyéni metabolizmusa csak kismértékben befolyásolta. Az eddigi eredményeink alapján érdemes további vizsgálatokat végezni annak eldöntésére, hogy a GA pezsgőpor hatásmechanizmusában az alkohol felszívódásának vagy/és az alkohol metabolizmusának befolyásolása játszik-e szerepet.
