“…It would be necessary to conduct studies focused exclusively on one group to clarify all the factors that can generate delusions of this type and others. However, when it comes to military and security forces personnel who, for various reasons, took amphetamines in the course of their professional duties, one can find information in scientific publications that may suggest predictors of delusions in this group [ 27 , 28 ]. However, this needs to be confirmed in research, which in this hermetically sealed group seems arduous.…”

Crystal methamphetamine, a potent psychostimulant, presents a complex clinical landscape. However, insights into the predisposing factors for suicidal tendencies among Iraqi users remain limited. Our study delves into these risks among 165 patients. Rigorous multivariable analysis was conducted, employing binary logistic regression, drawing from patients from Baghdad Medical City and Ibn-Rushd Teaching Hospital. Most participants were in their third decade (26.62 ± 0.53 years). Regarding suicidal ideation, our model demonstrated robust accuracy, supported by the Hosmer–Lemeshow goodness-of-fit test (NagelKerke’s R2 = 0.49, accuracy = 79.4%, p = 0.885). Notably, chronic methamphetamine use exceeding a year (OR = 6.15, p = 0.001), absence of psychological trauma (OR = 4.58, p = 0.006), and incidence of visual hallucinations (OR = 4.52, p = 0.001) rendered users more susceptible to suicidal ideation. Furthermore, our investigation unveiled risk factors tied to psychotic features and withdrawal manifestations. The study underscores pivotal predictors of suicidal ideation, warranting interdisciplinary vigilance from psychiatrists, clinical psychologists, and social workers. By monitoring at-risk individuals, progression toward the intricate spectrum of suicide can be potentially averted. These findings illuminate the urgency of tailored interventions for crystal methamphetamine users, contributing to enhanced holistic care.

“…Based on Kamienski report, [45] a molar ratio 1/0.5 (OH/n,s-Bu 2 Mg) was chosen to form the magnesium dialkoxide. 2,4-Dimethyl-3-pentanol was deprotonated with either n,s-Bu 2 Mg or Et 2 Mg and used as initiator for substituted epoxides, i.e., PO and BO, polymerization in the presence of triisobutylaluminum ( Table 1).…”

A family of extremely strong Brönsted bases called phosphazene superbases, [13] was also employed as effective organic catalysts or promoters for the polymerization of various types of monomers, including epoxides. [14][15][16][17][18][19][20][21][22] Due to their high basicity, non-nucleophilic nature, good solubility in a wide range of solvents, and easy handling, phosphazene bases can be readily used to turn protic moieties into nucleophilic initiating sites through deprotonation or activation of weak nucleophiles. Hydroxyl groups were the most commonly employed protic moieties due to their wide variety and high availability. Some recent reports have also demonstrated the deprotonation of other protic precursors, i.e., thiol, [23][24][25][26] amide, [27][28][29] and carboxylic acid [30] for effective polymerizations of cyclic monomers with mostly t-BuP 4 superbase. The obtention of hydroxy telechelic poly(propylene oxide) appears still limited by transfer to monomer reactions, giving chains initiated by an allyloxy group and limiting the molar masses. Their present high cost may also limit their use in industry.Besides, some studies have shown that a simple dibutylmagnesium (Bu 2 Mg) enables the synthesis of polyesters by ring-opening polymerization of lactides or lactones with residual transesterification side reactions. [31][32][33][34][35] Alcohols with different steric bulk and acidity, including iPrOH, PhCH 2 OH, Ph 2 CHOH, and Ph 3 COH, were employed with Bu 2 Mg to form magnesium alkoxides. The generated system was shown to improve the polymerizability of cyclic esters in dilute solutions by increasing the molar masses and narrowing the dispersity values where alcohols acts as control transfer agents. [36][37][38][39] We demonstrated in a previous work that propylene oxide can be polymerized with magnesium alkoxides (ROMgX) prepared from Grignard precursors in combination with triisobutylaluminum. [40] Starting from an alcohol, Grignard reagents were used as sustainable deprotonating agents for the generation of alkoxides of magnesium halide. The so-formed active species were able to initiate and poly merize propylene oxide in a controlled way. Competitive initiations were nevertheless observed. The main one was coming from the halide of the Grignard. The work presented in this article concerns a halide-free system based on dialkylmagnesium compounds used as deprotonating agents of protic
